  A mode for carrying out the present invention will be described.

  The agricultural machine of the present invention is an agricultural machine that is attached to a tractor and performs agricultural work. And it has the determination system which detects more accurately whether the agricultural machine is working. A basic configuration of this determination system is shown in FIG. This determination system includes movement detection means 1, work posture detection means 2, turning detection means 3, determination means 4, calculation means 5, and display unit 6. Note that turning detection means 3 Is configured as needed. The determination means 4 and the calculation means 5 can acquire information from the movement detection means 1 and the work posture detection means 2 and, if necessary, from the turning detection means 3. The results of the determination unit 4 and the calculation unit 5 are displayed on the display unit 6 and reflected in the control of the control unit 7 as necessary.

  The movement detection means 1 detects whether or not the farm work machine is moving. Usually, in a farm working machine that is attached to a tractor and performs farm work, the farm work machine moves while moving. Therefore, information relating to the movement of the agricultural machine can be detected by the movement detection means 1 and transmitted to the determination means 4.

  The work posture detection means 2 detects whether or not the agricultural machine is in a work posture. Usually, in a farm machine that is attached to a tractor and performs farm work, the attitude of the farm machine can be changed by raising and lowering the farm machine with a hydraulic device or the like equipped on the tractor. When the agricultural machine works, it works according to the working posture. For this reason, information regarding whether or not the agricultural machine is in a work posture can be detected by the work posture detection means 2 and transmitted to the determination means 4.

  The turning detection means 3 detects whether or not the tractor equipped with the farm work machine is turning. Usually, when the tractor is swung largely, it is a case where the direction is changed, and in this case, there is often no work by the agricultural machine. Therefore, information regarding whether or not the tractor equipped with the agricultural machine is turning can be detected by the turning detection means 3 and transmitted to the determination means 4.

  The determination means 4 determines whether or not the agricultural machine is working. The determination by the determination unit determines whether the agricultural machine is moving based on the information from the movement detection unit 1. Based on the information from the work posture detection means 2, it is determined whether or not the agricultural machine is in a work posture. When it is determined that the agricultural machine is moving and the agricultural machine is in a working posture, it is determined that the agricultural machine is in operation.

  Further, in the case of obtaining information on whether or not the tractor is turning from the turning detection means 3, if it is determined that the tractor is turning based on the information from the turning detection means 3, the farm work machine is moving. Even if it is determined that the agricultural machine is in a working posture, it is determined that the agricultural machine is not working. This is because, as described above, when the tractor is largely turned, there are many cases where the work by the agricultural machine is not performed.

  The calculation means 5 is a means for performing a necessary calculation based on the determination information as to whether or not the agricultural machine of the determination means 4 is working. Specific examples will be described later. It is assumed that the calculation unit 5 can acquire necessary information from other than the movement detection unit 1 and the work posture detection unit 2 as necessary. The determination means 4 and the calculation means 5 are comprised with the electronic device etc. for fulfill | performing said function, and may be comprised in the same location, or may be comprised separately.

  The display unit 6 is a means for displaying the determination result by the determination means 4 and the calculation result by the calculation means 5. For example, if these results are displayed on the screen installed near the driver's seat of the tractor or the screen of the operation box BOX of the work machine, it is possible to provide the worker with easy-to-understand information on the work of the farm work machine.

  The control unit 7 performs control related to the work of the farm working machine based on the determination result by the determination unit 4 and the calculation result by the calculation unit 5. Thereby, the determination result by the determination means 4 and the calculation result by the calculation means 5 can be reflected in the work of the agricultural machine.

  Specific examples of the movement detection means 1 and the work posture detection means 2 will be described.

  First, the movement detection unit 1 is a unit based on vehicle speed information acquired from a tractor. Depending on the tractor, information on the vehicle speed of the tractor may be acquired as an external output from the tractor side. In this case, the movement detection unit 1 acquires the information and transmits information based on the information to the determination unit 4. The determination means 4 determines whether or not the tractor is moving based on this information. When the judging means 4 judges that the vehicle is moving, it is not only when the vehicle speed of the tractor is simply coming out, but also when the vehicle speed is within the speed range suitable for the work of the agricultural machine. You may judge.

  A case where the work posture detection means 2 is an inclination sensor will be described. The inclination sensor is attached to the agricultural machine and transmits information based on the inclination sensor to the determination means 4. Agricultural machines often have a different working angle and a non-working angle lifted from the working posture. If the angle in this case is measured by an inclination sensor and determined by the determination means 4 based on this, is the working posture? It can be determined whether or not. In other words, when the angle detected by the tilt sensor is within the range of the angle suitable for the working posture of the agricultural machine, the determination unit 4 determines that the agricultural machine is in the working posture. Since the tilt sensor is lightweight, there is little increase in the weight of the agricultural machine and the impact on the matching balance with the tractor is minimal.

  2-4 is a figure which shows the example of the ground ring apparatus 10 which served as the movement detection means 1 and the work attitude | position detection means 2. FIG. 2 is a side view, and FIG. 3 is a front view. FIG. 4 is a diagram when the limit switch 17 is turned on. The ground ring device 10 can be retrofitted to a farm machine, and this system can be constructed without being affected by the type or presence of vehicle speed information of the tractor.

  In the grounding wheel device 10, a grounding wheel 11 having an anti-slip member 11 a around it is rotatably attached to a mounting arm 12 via a shaft member 16. The slip prevention member 11a is attached with a member for accurately rotating when the grounding wheel 11 touches the ground and the farm work machine moves as necessary. A rotation sensor 15 that detects the rotation of the ground ring 11 is attached to the side surface of the mounting arm 12. The upper part of the attachment arm 12 is joined to the lower part of the rod-like member 13, and the rod-like member 13 is attached to the upper part of the rod-like member 13 so as to protrude from the side so that the stopper member 14 becomes a projection. On the other hand, a base member 18 is provided below the stopper member 14 so as to penetrate the rod-like member 13 and be slidable. A spring 22 is attached between the mounting arm 12 and the base member 18 so as to enclose the rod-shaped member 13 on the outer peripheral portion of the rod-shaped member 13. The limit switch 17 is installed on the base member 18, and a switch bar 17 a included in the limit switch 17 is disposed so as to cross the upper side of the stopper member 14. The base member 18 is joined to the attachment member 19, and the attachment member 19 is configured to be attached to the frame pipe 30 included in the agricultural machine together with the nut 21 and the like together with the fixing member 20.

  Here, the means by detecting the rotation of the grounding wheel 11 by the rotation sensor 15 becomes the movement detecting means 1 for detecting whether or not the farming machine is moving, and the means by the limit switch 17 of the grounding wheel device 10 is operated by the farming machine. The work posture detection means 2 detects whether or not the posture. These pieces of information can be transmitted to the determination means 4.

  When the agricultural machine is in a non-working posture (the state shown in FIGS. 2 and 3), the grounding wheel 11 is lowered downward by its own weight and the biasing force of the spring 22. At this time, since the switch bar 17a of the limit switch 17 is not in contact with the stopper member 14, the limit switch 17 is in an OFF state, and the determination unit 4 determines that the farming machine is not in a working posture, and determines that it is not working. .

  On the other hand, when the agricultural machine is in the working posture (FIG. 4), the position of the frame pipe 30 is lowered and the position of the base member 18 is also lowered by lowering the agricultural machine to the ground 23 side. At this time, since the ground ring 11 contacts the ground 23, the distance between the base member 18 and the ground ring 11 approaches, and the spring 22 contracts. Therefore, the stopper member 14 pushes up the switch bar 17a of the mitt switch 17, and the limit switch 17 is in the ON state, and the determination unit 4 determines that the farm work machine is in the working posture. In this state, when the agricultural machine starts to move, the grounding wheel 11 rotates and the rotation sensor 15 detects this rotation. At this time, the determination means 4 determines that the agricultural machine is moving. Based on these two conditions, the determination unit 4 determines that the agricultural machine is working. In addition, when determining with the determination means 4 being moving, not only when rotation of the rotation sensor 15 has just come out, but the range of rotation is within the range of the rotation by the moving speed suitable for the operation | work of an agricultural machine. It may be determined that the user is moving.

  A specific example of the turning detection means 3 will be described. As the turning detection means 3, means using a gyro sensor or an acceleration sensor are applied, and these measure the acceleration and angular velocity when the tractor turns. The installation is arranged where the tractor can measure the acceleration and angular velocity when turning. Specifically, it may be on the tractor side, but it is more preferable on the work machine side because it can greatly measure acceleration and angular velocity because it greatly touches when turning.

  Next, an example in which the determination system is applied to a specific agricultural machine is shown in the following examples.

  The agricultural machine shown in Example 1 is a spreader that performs fertilization and sowing. FIG. 5 is a side view of the agricultural working machine according to the first embodiment when in a working posture. FIG. 6 is a side view of the agricultural machine according to the first embodiment when not in a working posture.

  The spreader of Example 1 is attached to the rear part of the tractor 41, and performs fertilization and sowing while plowing with the plowing part. Fertilizer is stored in the fertilizer container 45, and the fertilizer in the container is discharged from the fertilizer outlet 43 through a hose by rotating the fertilizer motor 44 installed at the lower part of the fertilizer container 45. Yes. The seed container 48 stores seeds, and the seed motor 47 installed at the lower part of the seed container 48 is rotated so that the seeds in the container are discharged from the seed outlet 46 via the hose. It has become.

  Here, the spreader of the first embodiment is provided with an inclination sensor 50 so that the difference in angle between the working posture and the non-working posture can be detected as shown in FIGS. The inclination sensor 50 serves as the work posture detection means 2. On the other hand, as the movement detection means 1, means based on vehicle speed information acquired from the tractor (for example, means for obtaining the vehicle speed detected by the tractor side sensor S1 by the tractor signal acquisition means S2) is applied. The determination result by the determination means 4 can be displayed on the display unit 6 provided in the vicinity of the driver's seat of the mounted tractor, so that the farm worker can be notified whether the farm work machine is working.

  Further, when the control of the control unit 7 is controlled by the fertilizer motor 44 and the seed motor 47, the farm working machine is working by the determination of the determination means 4 by the movement detection means 1 and the work posture detection means 2. Only in the case of determination, the fertilizer motor 44 and the seed motor 47 may be rotated to perform fertilization and sowing. Thereby, when the work machine is stopped or raised, fertilizer and seeds are not discharged, and wasteful fertilization and sowing can be prevented.

  In addition, the calculation means 5 can calculate the application amount and the remaining amount. This can be done by setting the amount of application per unit time by rotating the fertilizer motor 44 and seed motor 47, or by obtaining the number of rotations of those motors and calculating the amount of application per unit time. In addition, the amount of application can be calculated by multiplying the time determined by the determination means 4 as being working. Further, the remaining amount can be calculated by subtracting the calculated application amount from a predetermined initial amount. These results can be displayed on the display unit 6 provided near the driver's seat of the tractor 41 to inform the farmer.

  In the first embodiment, the movement detection unit 1 is a unit based on vehicle speed information acquired from a tractor, and the work posture detection unit 2 is a tilt sensor 50. In addition to this, the movement detection unit 1 has been described with reference to FIGS.

Further, the turning detection means 3 (gyro sensor (acceleration sensor) 60) can be installed as necessary.

  FIG. 7 is a side view of the agricultural machine according to the second embodiment, and FIG. 8 is a front view of the agricultural machine according to the second embodiment. The farm working machine shown in the second embodiment is a spreading machine that spreads contents such as fertilizer in the hopper 63.

  In the spreader of the second embodiment, the mounting portion 65 is mounted on the rear portion of the tractor, and the contents of lime and chemical fertilizer are stored in a stainless hopper 63. When the agitator 64 is rotated, the content outlet 66 The contents fall off and are spread on the field. Further, a slide plate 67 is formed at the content outlet 66, whereby the size of the content outlet 66 can be adjusted, and the amount of spraying per unit time can be adjusted. Furthermore, it has a motor 61 and a stopper 62 connected to the motor 61 via a link mechanism. By operating the motor 61, it is possible to operate whether the stopper 62 is also operated and the content outlet 66 is blocked. The contents outlet 66 can be opened and closed.

  Here, in the spreader according to the second embodiment, the inclination sensor 50 is installed at a place where the sensor appropriately operates, and the difference in angle between the working posture and the non-working posture can be detected. The inclination sensor 50 serves as the work posture detection means 2. On the other hand, as the movement detection means 1, means based on vehicle speed information acquired from the tractor (for example, means for obtaining the vehicle speed detected by the tractor side sensor S1 by the tractor signal acquisition means S2) is applied. Further, in the spreader according to the second embodiment, the turning detection means 3 (gyro sensor (acceleration sensor) 60) is installed at a place where the sensor appropriately operates, so that the turning of the tractor can be detected. . The determination result by the determination means 4 can be displayed on the display unit 6 provided in the vicinity of the driver's seat of the mounted tractor, so that the farm worker can be notified whether the farm work machine is working.

  Further, the control of the control unit 7 is controlled by the motor 61, and it is determined that the farm working machine is working by the determination of the movement detection unit 1, the work posture detection unit 2, and the determination unit 4 by the turning detection unit 3. Only in such a case, the stopper 62 is operated by the motor 61 to open the contents outlet 66 and perform spraying. Otherwise, it can be configured to be “closed” and not sprayed. As a result, when the agricultural machine is stopped or raised, the contents are not sprayed during turning, and wasteful spraying can be prevented.

  In addition, the calculation means 5 can calculate the application amount and the remaining amount. This is done by setting the spraying amount per unit time by adjusting the size of the content outlet 66 of the slide plate 67, or by calculating the spraying amount per unit time from the position of the slide plate 67. In addition, the amount of application can be calculated by multiplying the time determined by the determination means 4 as being working. Further, the remaining amount can be calculated by subtracting the calculated application amount from a predetermined initial amount. These results can be displayed on the display unit 6 provided in the vicinity of the driver's seat of the mounted tractor, and can be notified to the farm worker.

  In the second embodiment, the movement detection means 1 is a means based on the vehicle speed information acquired from the tractor, and the work posture detection means 2 is the inclination sensor 50. In addition, the movement detection means 1 has been described with reference to FIGS. The configuration of the movement detection means 1 and the work posture detection means 2 by the ground ring device 10 can also be applied.

  FIG. 9 is a plan view of the agricultural machine according to the third embodiment. The farm working machine of Example 3 is a paddy coater.

  The basket coater according to the third embodiment is mounted on the rear part of the tractor 71, scrapes old clay soil by the tilling unit 72, and shapes the scraped soil into a basket shape by the trimming unit 73. In addition, the above-described grounding ring device 10 is installed in the coater of the third embodiment. As a result, the movement detecting unit 1 and the work posture detecting unit 2 are configured, and the agricultural unit is operated by the determination unit 4. It is determined whether or not. The determination result by the determination means 4 can be displayed on the display unit 6 provided in the vicinity of the driver's seat of the mounted tractor, so that the farm worker can be notified whether the farm work machine is working.

  Further, the calculation means 5 can calculate the total work distance in which the ridges are formed. This is based on the information on the number of revolutions from the rotation sensor 15 of the grounding wheel device 10 and the data on the distance associated with the predetermined rotation, and the calculation means 5 calculates the sum of the distances when the judgment means 4 judges that the work is in progress. It is possible to calculate with. These results can be displayed on the display unit 6 provided in the vicinity of the driver's seat of the mounted tractor, and can be notified to the farm worker. Thereby, the working distance can be accurately grasped.

  Even if it is not the grounding wheel device 10, the inclination sensor 50 installed in the coater shown in the above embodiment is used as the work posture detection means 2, and means based on vehicle speed information acquired from the tractor (for example, tractor The movement detection means 1 may be a means for obtaining the vehicle speed detected by the side sensor S1 by means of the tractor signal acquisition means S2. In this case, the calculation of the working distance by the calculating means 5 is possible by using the vehicle speed information acquired from the tractor. Further, the turning detection means 3 (gyro sensor (acceleration sensor) 60) can be installed as necessary.

  On the other hand, FIG. 10 is a top view which shows an example at the time of attaching a watering apparatus to the agricultural machine of Example 3. FIG.

In this configuration, the feed nozzles 84 and 85 are discharged to the vicinity of the trimming unit 73. Thereby, when the disc-shaped trimming portion 73 rotates to shape the ridges, it is possible to prevent the soil from drying out and failing to accurately shape the ridges.

  At this time, discharge of water by the watering device is added to the above-described means based on the vehicle speed information acquired from the grounding wheel device 10 or the inclination sensor 50 and the tractor (turning detection means 3 (sensor 60) if necessary) ), It is possible to control the control unit 7 so that water is sprayed when the farming machine determines that the work is being performed by the determination unit 4 and is not sprayed when it is determined that the farm is not working. Examples of control include control that does not activate the motor for discharging when it is determined that the work is not being performed, and control that closes the discharge path such as the connection hose 82 and the nozzles 84 and 85 via some power mechanism. It is done. With these configurations, wasteful discharge of water in the tank 81 can be prevented.

  In each of the above-described embodiments, the work posture detection means 2 is a means for obtaining the position of raising and lowering the farm work machine by the tractor (for example, information on the position detected by the tractor side sensor S1) instead of the inclination sensor 50.
