Here, taking the second power output element 232 as an example of an air cylinder, the second power output element 232 drives the air cylinder to rotate through force transmission, and the air cylinder drives the second output shaft 233 to rotate during rotation, so as to realize the effect that the second sandwich plate 234 drives the sample tank 4 to rotate.
In another embodiment, the rotating assembly includes a third power output member 236, a driving wheel 237 and a driven wheel 235, the driving wheel 237 is mounted at an output shaft end of the third power output member 236, the third power output member 236 may employ a motor in practice but is not limited thereto, the driven wheel 235 is mounted on a second power output member 236 (generally, a cylinder surface of an air cylinder), the driven wheel 235 is coaxially arranged with the second output shaft 233 of the second power output member 236, the driving wheel 237 is in transmission connection with the driven wheel 235 (a belt or a chain may be employed, but not limited thereto), and the third power output member 232 drives the driving wheel 237 to rotate and drive the sample tanks 4 to synchronously rotate along with the second clamping plate 234.
In the above embodiment, the principle in the transmission process is the same, that is, the sample tank 4 is clamped and positioned by synchronously clamping the first clamping plate 224 and the second clamping plate 234, and the sample tank 4 is driven to rotate by the rotating assembly, and the driving mode of the rotating assembly is to drive the second power output part 232 so as to indirectly drive the second clamping plate 234 to rotate, and in the rotation process, the first clamping plate 224 follows the sample tank 4 to rotate passively.
The design of the limiting assembly is as follows:
in order to ensure that the sample tank 4 can reach a preset rotation angle and stop in the rotation process, the rotary material pouring device 2 further comprises a limiting component, wherein the limiting component is mounted on the housing 21 and used for limiting the rotating component to drive the sample tank 4 to rotate to the preset angle in the accommodating cavity 24.
In another embodiment, the limiting component includes a limiter 26 and a rotator 27, the limiter 26 is fixedly connected to the housing 21, the rotator 27 is rotatably connected to the housing 21, the rotator 27 synchronously rotates with the sample tank 4, and the limiter 26 limits the rotation angle of the rotator 27. Here, as will be understood by those skilled in the art, the rotator 27 is rotated synchronously with the sample tank 4 to realize real-time feedback of the rotation angle information of the sample tank 4. Specifically, one end of the rotator 27 extends to the inside of the housing 21, the other end of the rotator 27 is located outside the housing 21, the rotator located inside the housing 21 is limited on the sleeve 25, in practice, the limitation can be implemented by using a key-groove connection manner, the embodiment does not limit the specific limitation manner, and the rotator 27 can rotate along with the sleeve 25, that is, the rotator 27 indirectly rotates along with the sample tank 4. It should be noted that the rotator 27 is externally fixed to the first pto member 222, and the first pto member 222 is also rotatable along the axial direction of the first output shaft 223, so that the first pto member 222 and the rotator 27 rotate synchronously during the rotation of the sleeve 25 and the sample tank 4.
In another embodiment, the stopper 26 has two first limiting surfaces 261 and two second limiting surfaces 262, the rotator 27 has a limiting portion 271, the limiting portion 271 rotates coaxially with the first clamping plate 224, the first limiting surface 261 and the second limiting surface 262 are both formed on the rotation path of the limiting portion 271, the first limiting surface 261 collides with the limiting portion 271 to form a first rotation position of the sample tank 4, and the second limiting surface 262 collides with the limiting portion 271 to form a second rotation position of the sample tank 4. Here, it can be understood by those skilled in the art that, in practice, the stopper 26 is configured as an approximately semicircular ring structure having an opening on one side, the opening size of the approximately semicircular ring structure determines the maximum rotation angle of the rotator 27, the inner side of the stopper 26 is an annular arc surface, the rotator 27 is configured as a circular ring structure and is fixedly connected to the outer edge of the protective shell 221, the outer circumferential radius of the rotator 27 is slightly smaller than the inner circumferential radius of the stopper 26, and the outer circumferential surface of the rotator 27 is provided with a stopper 271, since the rotator 27 can rotate around the axis of the stopper 26 and limit the rotation path to the position of the opening of the stopper 26, that is, when the rotator 27 touches the first stopper surface 261 and the second stopper surface 262 of the stopper 26, the rotator 27 stops. In connection with the rotation position of the sample tank 4, it is understood that when the sample tank 4 is in an unpoured state (i.e. just enters the rotary material pouring device 2 and is limited), the first abutting surface 2711 on one side of the limiting part 271 contacts the first limiting surface 261 and makes the rotation position of the sample tank 4 in a first rotation position (the first rotation position is the initial positioning position of the sample tank 4); accordingly, in the process of implementing the pouring rotation of the sample tank 4, when the second abutting surface 2712 on the other side of the limiting part 271 contacts the second limiting surface 262, the rotating position of the sample tank 4 is in the second rotating position (the second rotating position is the final pouring position of the sample tank 4). It should be emphasized that, in the rotation process of the rotation body 27, the limit portion 271 may respectively collide with the first limit surface 261 and the second limit surface 262, and the rotation body 27 may transmit the impact force to the sample tank 4 through the force transmission of the plurality of components, so that the sample tank 4 may vibrate no matter when the limit portion 271 collides with the first limit surface 261 or the second limit surface 262, and the vibration may vibrate the material located on the inner wall of the material accommodating chamber 411 to fall off, and when the vibration is applied to dumping the material, the vibration may effectively dump the material in the material accommodating chamber 411, thereby effectively reducing the material residual amount in the material accommodating chamber 411.
An adjusting member 28 is mounted on the limiting portion 271, the adjusting member 28 has an end portion which impacts the first limiting surface 261 or/and the second limiting surface 262, and the adjusting member 28 drives the sample tank 4 to have a third rotation position or a third rotation position and a fourth rotation position through the position adjustment of the adjusting member 28 relative to the limiting portion 271. The following description is made with reference to specific examples:
in practice, the adjusting member 28 may be adjustably mounted on the limiting portion 271 by a screw, and the screw is perpendicular to the end surface of the limiting portion 271, so that the end of the screw may hit the first limiting surface or the second limiting surface.
The first embodiment is as follows: only adjustment of the initial positioning position of the sleeve 25 is carried out (i.e. the body of revolution 27 is set back to drive the inner sleeve 25 in the preset position);
in this test example, because in the long-term impact touch process, the initial positioning position of the sleeve 25 may deviate, that is, the position adjustment of the first abutting surface 2711 relative to the first limiting surface 261 is realized by rotating the screw, it should be noted that, because of the possibility of the deviation of the sleeve 25 to two opposite directions, when the real-time initial position correction is performed, and when the sleeve 25 is located at the preset position, the screw is installed at the end surface of the first abutting surface 2711 and extends out to the end surface of the first abutting surface 2711 by a certain length, so that the extension and retraction adjustment of the screw can be realized, that is, the two direction positions of the rotational displacement of the sleeve 25 can be adjusted, and the sample tank 4 can be driven to have the third rotational position after the adjustment.
Example two: only the positional adjustment of the pouring angle of the sample tank 4 is performed (i.e., the position of the sample tank 4 at the time of pouring is adjusted);
in this test example, the second abutting surface 2712 is adjusted relative to the second limiting surface 262 by rotating the screw, and similarly to the adjustment mode of the first test example, the screw is installed on the end surface of the second abutting surface 2712 and extends to a certain length of the end surface of the second abutting surface 2712, so that the screw can be adjusted in extension and contraction, and the position of the sample tank 4 during pouring can be adjusted. When the screw is extended, i.e. the abutment surface II 2712 is further away from the second limiting surface 262, the pouring angle of the sample tank 4 is reduced; when the screw is retracted, i.e. the abutment surface II 2712 is closer to the second stopper surface 262, the pouring angle of the sample tank 4 is increased, and the adjustment drives the sample tank 4 to have a third rotational position.
Example three: the adjustment of the initial positioning position of the sleeve 25 and the position adjustment of the pouring angle of the sample tank 4 are simultaneously carried out;
with reference to the first and second test examples, the first abutting surface 2711 and the second abutting surface 2712 of the limiting portion 271 are respectively provided with a screw in a staggered manner, so that the requirements for implementing the adjustment of the initial positioning position of the sleeve 25 and the position adjustment of the inclination angle of the sample tank 4 can be met, the first and second test examples are described separately, and are not described herein in detail, and the sample tank 4 can be driven to have a third rotation position and a fourth rotation position at the initial positioning position and the inclination position after adjustment.
Design of the sleeve 25:
the sleeve 25 is installed in the accommodating cavity 24, the sleeve 25 is provided with an accommodating through hole 251 for accommodating the sample tank 4, the sleeve 25 and the sample tank 4 are driven to rotate synchronously by a rotating component, and here, a person skilled in the art needs to understand that the sleeve 25 is arranged in the accommodating cavity 24 and is rotatably connected to the inside of the accommodating cavity 24 at the outer wall, and the rotation central axis of the sleeve 25 coincides with the axes of the first output shaft 223 and the second output shaft 233, so that the sleeve 25 and the sample tank 4 can synchronously rotate along with the first output shaft 223 and the second output shaft 233. In the implementation, the first clamping plate 224 and the second clamping plate 234 are symmetrically arranged and are adapted to the notch 412 of the sample tank 4 in a plate shape, the central portion of the sleeve 25 is formed with a receiving through hole 251, the two sides of the sleeve 25 are respectively formed with a first opening 252 and a second opening 253, and the first clamping plate 224 can freely shuttle over the first opening 252 and is limited on the notch 412, and the second clamping plate 234 can freely shuttle over the second opening 253 and is limited on the notch 412. The sample tank 4 has a material accommodating chamber 411, and the material accommodating chamber 411 has an outlet part, and the caliber of the outlet part is smaller than the caliber of the discharge hole 243 at the side close to the accommodating cavity 24, so that the material can be discharged completely through the discharge hole 243 in the material pouring process, and the material scattering in the accommodating cavity 24 is prevented.
Third, the butt joint device 3
The docking device 3 is provided with a conveying pipeline 33 and a sleeve 31 sleeved outside the conveying pipeline 33, the sleeve 31 is driven by a third transmission piece 32, after the sample tank 4 enters the sleeve 25 through the conveying pipeline 33, the sleeve 31 is driven by the third transmission piece 32 in a feeding way and abuts against the lower opening part of the sleeve 25; meanwhile, the sleeve 17 is driven by the transmission member one 15 to be fed in the same way and abuts against the upper opening part of the sleeve 25, so that the sleeve 25 can be further limited by the common limiting effect of the sleeve 31 and the sleeve 17, and meanwhile, when the joint is sealed by a rubber ring, the sleeve 17, the sleeve 25 and the sleeve 31 can form a relatively sealed internal pipeline system to facilitate the transmission of the sample tank 4 to the inside of the rotary pouring device 2 in a pneumatic transmission manner.
