Detailed Description

The technical solutions in the implementation manner of the present application will be clearly and completely described below with reference to the drawings in the implementation manner of the present application, and it is obvious that the described implementation manner is only a part of the implementation manner of the present application, not all the implementation manners.

Referring to fig. 1, fig. 1 is a schematic diagram of an agricultural machine 100 according to an embodiment of the present application. It is understood that the agricultural machine 100 is used to perform crop planting or harvesting operations. For example, the agricultural machine 100 may be a grain combine (Combine Harvester), which is a harvesting machine that can perform harvesting, threshing, unloading, etc. of cereal crops at a time, thereby directly harvesting grains from the field.

In this embodiment, the agricultural machine 100 may include a main body 10, a work mechanism 20, a driving mechanism 30, and a clutch device 200. The body 10 is movable under electric drive. The operating mechanism 20, the driving mechanism 30 and the clutch device 200 are mounted on the machine body 10, and the operating mechanism 20 is used for harvesting, threshing, unloading grains and the like of crops. The drive mechanism 30 is configured to generate power for driving the work mechanism 20 to operate under electric drive. The clutch device 200 is detachably connected to the working mechanism 20 and the driving mechanism 30, i.e., the working mechanism 20 and the driving mechanism 30 are detachably connected by the clutch device 200. The clutch device 200 is used to transmit power generated by the driving mechanism 30 to the working mechanism 20 to drive the working mechanism 20 to operate. The clutch apparatus 200 is also used to stop the power transmission of the driving mechanism 30 to the working mechanism 20 to stop the operation of the working mechanism 20.

It is understood that agricultural machine 100 may include a plurality of work mechanisms 20 and a plurality of drive mechanisms 30. The plurality of operating mechanisms 20 can implement different operating functions for crops, such as a harvesting function, a threshing function, a grain unloading function, etc., and the plurality of driving mechanisms 30 are respectively used for driving the corresponding operating mechanisms 20 to operate.

Referring to fig. 2 and 3 together, in the present embodiment, the clutch apparatus 200 may include a clutch mechanism 40 and a clutch control device 300. The clutch mechanism 40 is used to connect the drive mechanism 30 and the working mechanism 20 to transmit power generated by the drive mechanism 30 to the working mechanism 20.

The clutch control device 300 is connected to the clutch mechanism 40, and the clutch control device 300 is used for controlling the clutch mechanism 40 to be in an engaged state or a disengaged state. When the clutch mechanism 40 is in the combined state, the power generated by the operation of the driving mechanism 30 can be transmitted to the operation mechanism 20, and the operation mechanism 20 can harvest, threshing or unloading crops. When the clutch mechanism 40 is in the disengaged state, the power generated by the operation of the drive mechanism 30 cannot be transmitted to the working mechanism 20, and the working mechanism 20 stops operating. That is, the clutch control device 300 can control the operation and stop of the working mechanism 20 by controlling the clutch mechanism 40 to switch between the engaged state and the disengaged state.

In this embodiment, the clutch mechanism 40 may include a tensioner assembly 41 and a belt 42. The drive mechanism 30 may include a drive wheel 31. Work mechanism 20 may include a driven wheel 21. The driving belt 42 is wound around the driving pulley 31 and the driven pulley 21. The tensioning assembly 41 may include a connection 412 and a tensioning wheel 411. The connector 412 may be rotatably coupled to the body 10. The tensioning wheel 411 can be rotatably connected to a connection piece 412. The circle center of the rotation of the tensioning wheel 411 and the circle center of the rotation of the connecting piece 412 are arranged at intervals, and the rotation of the connecting piece 412 can drive the tensioning wheel 411 to rotate along the same circumferential direction, so that the distance between the tensioning wheel 411 and the driving belt 42 is changed, namely, the tensioning wheel 411 synchronously rotates along with the connecting piece 412 to press or loosen the driving belt 42.

It will be appreciated that when the clutch mechanism 40 is in an engaged state, such as the tensioner 411 is pressing against the belt 42 to tension the belt 42, the belt 42 is in close contact with the drive pulley 31, the driven pulley 21, as shown in fig. 3. At this time, the rotation of the driving wheel 31 may drive the driven wheel 21 to rotate, and further transmit the power of the driving mechanism 30 to the working mechanism 20, so that the working mechanism 20 works.

As shown in fig. 2, when the clutch mechanism 40 is in a disengaged state, for example, the tension pulley 411 releases the belt 42 to loosen the belt 42, the static friction force between the belt 42 and the driving pulley 31, the driven pulley 21 is reduced. At this time, the rotation of the driving wheel 31 cannot drive the driven wheel 21 to rotate synchronously, and the working mechanism 20 stops working.

In this embodiment, the clutch control device 300 may include a connection rope 50, a driving assembly 60 and a processor 70, where the connection rope 50 may be a hard rope body deformed under the action of an external force, one end of the connection rope 50 is connected to the connecting piece 412, and the other end is connected to the driving assembly 60. The processor 70 is communicatively connected to the driving assembly 60, and the processor 70 is configured to control the driving assembly 60 to drive the connecting rope 50 to move, so as to drive the connecting piece 412 to rotate synchronously. In this way, synchronous rotation of the connection 412 will control the tensioning wheel 411 to press or release the belt 42.

It will be appreciated that the communication connection may be a wired communication connection implemented by wires or a wireless communication connection implemented by communication means, which is not limited in the embodiments of the present application.

It is understood that the connecting cord 50 may be a metal cable with deformation capability and the material may be, but is not limited to, iron alloy, copper alloy, etc.

It should be understood that the positional relationship among the connecting cord 50, the driving component 60 and the tensioning component 41 is not limited in the embodiments of the present application, and it is only necessary to ensure that when the driving component 60 drives the connecting cord 50 to move, the connecting cord 50 may be elastically deformed according to the positional relationship among the connecting cord 50, the driving component 60 and the tensioning component 41, for example, when the driving component 60 drives the connecting cord 50 to move, since the driving component 60 and the tensioning component 41 are located on different planes, or since other components in the body 10 are blocked between the driving component 60 and the tensioning component 41, part of the connecting cord 50 may be bent.

It will be appreciated that when a plurality of work mechanisms 20, a plurality of drive mechanisms 30, and a plurality of clutch mechanisms 40 are provided on the agricultural machine 100, a plurality of clutch control devices 300 may be provided on the agricultural machine 100. Each clutch control device 300 is used for controlling the corresponding clutch mechanism 40 to switch between the disengaged state and the engaged state.

It will be appreciated that in other embodiments, when multiple work mechanisms 20 and multiple drive mechanisms 30 are provided on an agricultural machine, only one clutch control device 300 may be provided on the agricultural machine 100. The clutch control device 300 may include a plurality of connection ropes 50 and a plurality of driving assemblies 60. Each connecting cord 50 corresponds to one clutch mechanism 40. Each driving assembly 60 is configured to drive the corresponding connecting rope 50 to move, so as to control the corresponding clutch mechanism 40 to switch between the disengaged state and the engaged state through the corresponding connecting rope 50.

It will be appreciated that in embodiments of the present application, the connection relationship between the connecting cord 50 and the connector 412 is not limited. For example, one end of the connecting cord 50 is hinged to the connecting member 412 by a rotational connecting work piece. The rotationally coupled workpieces may be, but are not limited to, hinges, pins, and the like.

For another example, as shown in fig. 2, a buffer member 51 is connected between the connecting rope 50 and the connecting member 412, and both ends of the buffer member 51 are rotatably connected to the connecting rope 50 and the connecting member 412, respectively.

It will be appreciated that when the tensioning wheel 411 presses against the belt 42, the belt 42 is elastically deformed and generates an elastic force, resulting in a reaction force against the tensioning wheel 411. When agricultural machinery 100 performs agricultural production, vibration generated when operation mechanism 20 and driving mechanism 30 work due to shaking generated during running of machine body 10, and/or elastic force generated by elastic deformation of driving belt 42, tensioning driving belt 42 tends to push tensioning wheel 411 to move. By providing the buffer 51 in this way, the elastic force of the belt 42 against the tension pulley 411 can be effectively buffered, and the possibility that the connecting rope 50 is pulled under the impact of the reaction force to loosen the tension pulley 411 from the belt 42 can be reduced.

It is understood that in embodiments of the present application, cushioning member 51 may be, but is not limited to, a spring.

It is understood that the buffer member 51 may be coupled to the connecting rope 50, the connecting member 412 by a rotational coupling work piece, which may be, but is not limited to, a hinge, a pin, etc.

It is appreciated that, as shown in fig. 2, in an embodiment of the present application, the clutch control device 300 may further include a housing 80. The drive assembly 60 is housed in a case 80. The case 80 is provided with a through hole 81, the through hole 81 communicates the inside and the outside of the case 80, the connection rope 50 is inserted through the through hole 81, and the portion of the connection rope 50 connected with the driving assembly 60 enters the case 80 through the through hole 81.

It will be appreciated that the housing 80 serves to protect the drive assembly 60 while protecting the connection point 631 of the connecting cord 50 to the drive assembly 60.

Referring to fig. 4, in some embodiments, the driving assembly 60 may include a driving member 61 and a transmission assembly. One end of the connecting cord 50 is connected to the transmission assembly. The driver 61 is communicatively coupled to the processor 70. The driving member 61 is used for driving the transmission assembly to move under the control of the processor 70, so as to drive the connecting rope 50 to move synchronously.

In some embodiments, the drive assembly may include a first drive member 62 and a second drive member 63. The first transmission member 62 is connected to the second transmission member 63 in a relatively movable manner. The first transmission member 62 and the second transmission member 63 may be gears, the driving member 61 may be a gear motor, the first transmission member 62 and the second transmission member 63 are both rotatably connected to the inner wall of the box 80, and the driving member 61 is fixedly mounted on the inner wall of the box 80. The driving member 61 can drive the first driving member 62 to move under the control of the processor 70, and the first driving member 62 drives the second driving member 63 and the connecting rope 50 to synchronously move.

It is understood that relatively movable may include relatively movable (e.g., linear) and may include relatively rotatable, as embodiments of the present application are not limited in this regard.

In this embodiment, there is a space between the center of the first transmission member 62 and the center of the second transmission member 63. The first transmission member 62 is coaxially fixed at the output end of the driving member 61, the second transmission member 63 is meshed with the first transmission member 62, the connecting rope 50 is hinged on the second transmission member 63, and a connecting point 631 of the connecting rope 50 on the second transmission member 63 is arranged at intervals with the circle center of the second transmission member 63.

It will be appreciated that the linear distance between the other parts of the second transmission member 63, except the center of the circle, and the through hole 81 may be changed according to the rotation of the second transmission member 63. That is, when the second transmission member 63 rotates, the linear distance between the connection point 631 and the through hole 81, that is, the length of the connection cord 50 entering the case 80 can be changed. For example, when the second transmission member 63 rotates to increase the length of the connecting rope 50 entering the box 80, the length of the connecting rope 50 outside the box 80 is reduced, and the second transmission member 63 may pull the connecting rope 50 to move, thereby driving the connection member 412 to rotate, so that the tension wheel 411 compresses the driving belt 42, and the clutch mechanism 40 enters the engaged state. For another example, when the second transmission member 63 is rotated to decrease the length of the connection rope 50 entering the case 80, the length of the connection rope 50 outside the case 80 is increased, and the tension pulley 411 is pushed by the elastic force generated when the transmission belt 42 is tensioned, so that the tension pulley 411 releases the transmission belt 42 and the clutch mechanism 40 is brought into the disengaged state.

It will be appreciated that in the embodiments of the present application, the first transmission member 62 and the second transmission member 63 may be complete gears or incomplete gears, which are not limited in this embodiment of the present application.

It will be appreciated that in the embodiments of the present application, the rotational connection of the first and second transmission members 62, 63, respectively, to the inner wall of the housing 80, and/or the articulation of the connecting cord 50 to the second transmission member 63, are defined in a reversed format. For example, the rotational connection of the first transmission member 62, the second transmission member 63 to the inner wall of the housing 80, and/or the articulation of the connecting cord 50 to the second transmission member 63 may be achieved by rotationally connecting the work pieces. The rotationally coupled workpieces may include, but are not limited to, pins, bearings, and the like. For another example, referring to fig. 4 and 5, in some embodiments, the second transmission member 63 may be rotatably connected to one end of the connecting rope 50 via the connecting shaft 52. Specifically, one end of the connecting rope 50 is fixedly connected with the connecting shaft 52, and the connecting shaft 52 is arranged through the second transmission member 63 and is rotatably connected with the second transmission member 63. A sliding groove 82 may be formed on the inner wall of the box 80, one end of the connecting shaft 52 is accommodated in the sliding groove 82, and the connecting shaft 52 is slidably connected with the sliding groove 82 along the rotation direction of the second transmission member 63.

It will be appreciated that the arrangement of the chute 82 effectively enhances the definition of the movement track of the connecting shaft 52 and further improves the stability of the movement of the connecting shaft 52.

It is understood that the connecting cord 50 may be wound around or threaded through the connecting shaft 52 to achieve a fixed connection of the connecting cord 50 to the connecting shaft 52.

It will be appreciated that referring again to fig. 4, in the embodiment of the present application, the clutch control device 300 further includes a contact switch 90. The contact switch 90 is mounted in the housing 80. The contact switch 90 may be an electronic switch triggered by interference, and may be, but is not limited to, a micro switch, a travel switch, etc.

It is understood that in the embodiment of the present application, the second transmission member 63 may include a main body 632 and a supporting portion 633. The main body 632 is integrally connected with the supporting portion 633, the main body 632 is rotatably connected with the inner wall of the box 80, and the supporting portion 633 can rotate to be supported by the contact switch 90 so as to trigger the contact switch 90. Specifically, the contact switch 90 may include a first switch 91 and a second switch 92. The first switch 91 and the second switch 92 may be fixedly mounted on the inner wall of the case 80. The first switch 91 and the second switch 92 are disposed at intervals in the circumferential direction. The driving member 61 may drive the second transmission member 63 to rotate, so that the abutting portion 633 rotates and abuts against the first switch 91 or the second switch 92 to trigger the first switch 91 or the second switch 92. Wherein, when the abutting part 633 moves along the direction of the second switch 92 towards the first switch 91 and abuts against the first switch 91, the clutch mechanism 40 is in a combined state; when the abutting portion 633 moves in the direction of the first switch 91 toward the second switch 92 and abuts against the second switch 92, the clutch mechanism 40 is in a disengaged state.

It can be appreciated that in the present embodiment, the main body 632 may be an incomplete gear, and the incomplete portion of the main body 632 extends along the diameter direction of the main body 632 to form the supporting portion 633.

It will be appreciated that embodiments of the present application do not limit the location of the connection point 631 on the second transmission member 63. For example, as shown in fig. 4, the connection point 631 may be located on the abutment 633.

In this embodiment, the first switch 91 and the second switch 92 may be disposed at intervals along a circumferential direction around the center of the main body 632.

In this embodiment, the chute 82 may be an arc chute with the center of the main body 632 as the center, and the opening length of the chute 82 may correspond to the angle formed by the connection line between the first switch 91 and the center of the main body 632 and the connection line between the second switch 92 and the center of the main body 632.

It will be appreciated that the first switch 91 and the second switch 92 disposed at intervals, and the chute 82 can limit the rotation stroke of the second transmission member 63, so as to avoid excessive pressing of the transmission belt 42 or insufficient tensioning of the transmission belt 42 caused by excessive or insufficient rotation angle of the second transmission member 63, and reduce damage to the transmission belt 42 or excessive power loss transmitted from the driving mechanism 30 to the working mechanism 20.

It is understood that in embodiments of the present application, the contact switch 90 is communicatively coupled to the processor 70. The processor 70 may determine whether the contact switch 90 is triggered and control the driving member 61 to stop operating when the contact switch 90 is triggered. For example, when it is determined that the first switch 91 or the second switch 92 is triggered, the processor 70 controls the driving member 61 to stop operating.

It will be appreciated that the connection point 631 forms a connection angle with the center of the body 632 and the center of the through hole 81 forms a connection angle with the center of the body 632. For example, the connection angle may be an angle α as shown in fig. 4. In this embodiment, the driving member 61 drives the supporting portion 633 to move along the direction of the second switch 92 toward the first switch 91, so as to adjust the connection angle to reach the preset angle.

It will be appreciated that the predetermined angle may correspond to the angle when the moment arm of the connection point 631 to the center of the body 632 is at or near a minimum. When the moment arm of the connection point 631 to the center of the main body 632 is minimized, the reaction force from the connection rope 50 borne by the output end of the driving element 61 is minimized or nearly minimized, so that the protection of the driving element 61 can be enhanced.

In one implementation, the included angle formed by the connection between the first switch 91 and the center of the second transmission member 63 and the connection between the second switch 92 and the center of the second transmission member 63 is a right angle. The chute 82 is a quarter circular arc slot centered with the center of the main body 632. One end of the chute 82 away from the second switch 92 is located on a straight line with the center of the main body 632 and the center of the through hole 81. When the abutting portion 633 rotates to move the connecting shaft 52 to an end of the chute 82 away from the second switch 92, the processor 70 controls the driving member 61 to stop working to stop the rotation of the abutting portion 633 when the abutting portion 633 abuts against the first switch 91. In this implementation, the maximum rotatable angle of the second transmission member 63 is 90 degrees, the preset angle may be 180 degrees, and the angle of the connection included angle may be adjusted from 90 degrees to 180 degrees.

It can be understood that, in the embodiment of the present application, the center of the second transmission member 63 is disposed corresponding to the through hole 81, and when the abutting portion 633 abuts against the first switch 91, that is, the connection angle reaches the preset angle, the connection line between the connection point 631 and the through hole 81 passes through the center of the second transmission member 63. Namely, the connecting line of the connecting point 631, the center of the second transmission member 63 and the three points of the through hole 81 is a straight line. At this time, the portion of the connection rope 50 located in the case 80 is tensioned and coincides with the connection point 631, the center of the second transmission member 63, and the connection line of the three points of the through hole 81, the linear distance between the connection point 631 and the through hole 81 is maximized, and the length of the connection rope 50 located in the case 80 is maximized. At this time, the position of the connection point 631 reaches the dead point position, and the reaction force received by the output end of the driving member 61 is minimized.

In another implementation, the included angle formed by the connection between the first switch 91 and the center of the second transmission member 63 and the connection between the second switch 92 and the center of the second transmission member 63 is an obtuse angle with an angle slightly greater than 90 degrees, for example, an angle of 95 degrees. The chute 82 is a circular arc slot centered with the center of the main body 632 and approximately one quarter of a circular arc slot. The connecting line between the end of the sliding groove 82 far away from the second switch 92 and the center of the through hole 81 is close to the center of the main body 632, and is positioned at one side of the center of the main body 632 far away from the second switch 92. In this implementation, the maximum rotatable angle of the second transmission member 63 is 95 degrees, the preset angle may be 185 degrees, and the angle of the connection included angle may be adjusted from 90 degrees to 185 degrees.

It can be understood that when the abutting portion 633 abuts against the first switch 91, i.e. the connection angle reaches the preset angle, the connection line between the connection point 631 and the through hole 81 approaches the center of the second transmission member 63, and is located at one side of the center of the second transmission member 63 away from the second switch 92. At this time, the position of the connection point 631 reaches a position close to the dead point, and the reaction force received by the output end of the driving member 61 is nearly minimized. At this time, the abutting portion 633 only tends to rotate in a direction away from the second switch 92 by the reaction force from the connection cord 50, and the end of the chute 82 away from the second switch 92 restricts the movement of the connection shaft 52 in a direction away from the second switch 92, that is, the rotation of the abutting portion 633 in a direction away from the second switch 92.

It can be understood that referring to fig. 3 and 4, when the clutch mechanism 40 is in the engaged state and the tensioning wheel 411 presses the driving belt 42, the connection point 631 is located at one side of the center of the second driving member 63 away from the through hole 81, and the connection line between the connection point 631, the center of the second driving member 63 and the center of the through hole 81 is a straight line or is close to a straight line. When the tension pulley 411 is pushed by the elastic force generated by the deformation of the belt 42 to move away from the belt 42, the link 412 tends to rotate and pull the link rope 50. At this time, since the connection line 50 is located in the box 80 and the connection line or the connection line of the connection point 631, the center of the second transmission member 63 and the center of the through hole 81 is approximately coincident, the direction of the traction force of the connection member 412 on the connection line 50 is the same or approximately the same as the length direction of the portion of the connection line 50 in the box 80, the direction of the connection point 631 towards the center of the second transmission member 63 is the same or approximately the same as the direction of the connection point 631 towards the center of the through hole 81, and at this time, the component force on the second transmission member 63 in the tangential direction of the arc of the second transmission member 63 can be 0 or approximately 0, thereby reducing the probability of the rotation of the second transmission member 63 under the pull of the connection line 50, and reducing the probability of the rotation of the tensioning wheel 411 and the connection member 412 under the elastic force of the transmission belt 42, so that the tensioning wheel 411 can continuously compress the transmission belt 42 to continuously maintain the engaged state of the clutch mechanism 40.

It will be appreciated that referring again to fig. 2 and 3, in some embodiments, the clutch control device 300 may further include an interaction component 110. The interaction component 110 is communicatively coupled to the processor 70. The interaction component 110 is configured to respond to an operator's operation and output a trigger instruction to the processor 70. The processor 70 may control the operation of the driver 61 in response to the trigger instruction.

It can be understood that the interaction component 110 may be an electronic device with a man-machine interaction function, and the operation of the interaction component 110 by an operator may be manually implemented on the interaction component 110, or may be implemented by the operator manually operating on other terminal devices, so that the other terminal devices send instructions to the interaction component 110.

In some embodiments, the interaction assembly 110 may include a remote operation member 111 and a physical operation member 112, the remote operation member 111 may be in wireless communication connection with the processor 70 through a communication device, and the physical operation member 112 may be fixedly mounted on the body 10 and in wired communication connection with the processor 70 through a data line. The operator may output a trigger instruction to the processor 70 by operating the physical operation member 112 when operating the body 10, or may output a trigger instruction to the processor 70 remotely by operating the remote operation member 111.

It will be appreciated that the physical operator 112 may be an operator panel on the fuselage 10; the remote operation member 111 may be an electronic device with a wireless communication function, including but not limited to a smart phone, a remote controller, a computer, etc.

Referring to fig. 2 and 3, in some embodiments, the clutch control device 300 may further include a memory 120. The memory 120 is used to store vehicle information of the agricultural machine 100, including rotational speed, vehicle speed, fault information, and the like. The processor 70 is communicatively coupled to the memory 120. When processor 70 receives the trigger instruction, processor 70 may retrieve the vehicle information from memory 120 and determine whether there is an anomaly in agricultural machine 100 based on the vehicle information. When processor 70 determines that there is an anomaly in agricultural machine 100, processor 70 does not respond to the trigger instruction. When processor 70 determines that there is no anomaly in agricultural machine 100, processor 70 may control operation of clutch mechanism 40 based on the trigger command. For example, processor 70 may read parameters such as rotational speed, vehicle speed, etc. in the vehicle information and determine whether the parameters are outside a preset threshold range, thereby determining whether agricultural machine 100 is abnormal. For another example, the processor 70 may read whether there is trouble information in the vehicle information, and further directly determine whether the agricultural machine 100 is abnormal.

In some embodiments, the vehicle information also includes a state of the clutch mechanism 40. In this manner, processor 70 may again determine whether the vehicle information meets the preset conditions upon determining that there is no anomaly in agricultural machine 100. When the vehicle information meets the preset condition, the processor 70 may control the driving member 61 to operate to drive the connection rope 50 to move; the processor 70 may not respond when the vehicle information does not meet the preset condition.

It will be appreciated that when the agricultural machine 100 has a plurality of work machines 20 and a plurality of clutch mechanisms 40, the trigger command may be for one work machine 20 of the plurality of work machines 20 and its corresponding clutch mechanism 40. The preset conditions can be multiple, and the multiple preset conditions are in one-to-one correspondence with the multiple different trigger instructions. The preset condition may be that one or more of the clutch mechanisms 40 is designated to be in an engaged state or a disengaged state among the plurality of clutch mechanisms 40.

It will be appreciated that when the agricultural machine 100 is operating, the plurality of operating mechanisms 20 on the agricultural machine 100 need to be started and operated sequentially according to a specified process, or when one or more of the operating mechanisms 20 are started and operated, some of the operating mechanisms 20 need to be kept in a closed state according to a specified operation requirement; since the power required for the operation of the work machine 20 is transmitted by the clutch mechanism 40, the processor 70 can determine whether or not the operation of the specified clutch mechanism 40 corresponding to the trigger command can be performed by determining the states of the plurality of clutch mechanisms 40 when the trigger command is received.

For example, referring to fig. 6, the plurality of working mechanisms 20 may include a threshing mechanism, a harvesting mechanism and a grain unloading mechanism, the corresponding plurality of clutch mechanisms 40 may include a threshing clutch, a harvesting clutch and a grain unloading clutch, and the plurality of preset conditions may include:

when the threshing clutch combination needs to be controlled, the harvesting clutch and the threshing clutch are required to be determined to be in a separation state;

when the threshing clutch needs to be controlled to be separated, the harvesting clutch needs to be determined to be in a separation state and the threshing clutch needs to be determined to be in a combination state;

when the harvesting clutch combination needs to be controlled, the threshing clutch needs to be determined to be in a combined state and the harvesting clutch needs to be in a separated state;

when the harvesting clutch needs to be controlled to be separated, the harvesting clutch needs to be determined to be in a combined state;

when the grain unloading clutch combination needs to be controlled, the grain unloading clutch needs to be determined to be in a separation state;

when the grain unloading clutch needs to be controlled to be separated, the grain unloading clutch needs to be determined to be in a combined state.

The working principle of the agricultural machine 100 provided in the embodiment of the present application is described below with reference to fig. 1 to 6:

after the operator outputs the trigger instruction to the processor 70 through the operation interaction component 110, the processor 70 receives the trigger instruction and acquires the vehicle information.

The processor 70 determines whether the agricultural machine 100 is abnormal according to the vehicle information, and determines whether the vehicle information meets a preset condition corresponding to the trigger instruction when the agricultural machine 100 is not abnormal. If the vehicle information meets the preset condition, the processor 70 controls the driving member 61 to operate.

As shown in fig. 3 and 4, the driving member 61 is operative to drive the first transmission member 62 to rotate, drive the second transmission member 63 to synchronously rotate, and drive the connecting rope 50 to move. When the clutch mechanism 40 is required to be switched from the disengaged state to the engaged state, the driving member 61 drives the abutting portion 633 to rotate from the second switch 92 to the first switch 91, so as to drive the connecting rope 50 to move synchronously. The connection rope 50 pulls the connection member 412 to rotate, so that the tension pulley 411 gradually presses the transmission belt 42. When the abutting portion 633 abuts against the first switch 91, the processor 70 determines that the first switch 91 triggers and controls the driving member 61 to stop working. At this time, the connecting rope 50 may coincide with the connecting point 631, the center of the second transmission member 63 and the connecting line where the through hole 81 is located, the tension pulley 411 compresses the transmission belt 42, and the power generated by the driving mechanism 30 is transmitted to the working mechanism 20, so that the working mechanism 20 works.

As shown in fig. 2, when the clutch mechanism 40 is required to be switched from the engaged state to the disengaged state, the driving member 61 drives the abutting portion 633 to rotate from the first switch 91 to the second switch 92, so as to drive the connection rope 50 to move synchronously. The tensioner 411 gradually loosens the belt 42. When the holding portion 633 is held against the second switch 92, the processor 70 determines that the second switch 92 triggers and controls the driving member 61 to stop working. At this time, the belt 42 is restored to be relaxed, and the power generated by the drive mechanism 30 cannot be transmitted to the working mechanism 20, so that the working mechanism 20 stops working.

In the embodiment of the application, through setting up drive assembly, can drive tensioning assembly 41 motion, and then replace the manual force application to the operation of tensioning assembly 41, reduced the manpower loss when operating clutch mechanism 40, improved the convenience of controlling clutch mechanism 40 simultaneously.

It will be evident to those skilled in the art that the present application is not limited to the details of the foregoing illustrative embodiments, and that the present application may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The above-described embodiments of the application are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
