[0002] With the development of economy, the production and circulation of seeds are increasing. Seed sorting is an important link to ensure the quality of seeds and promote the process of seed industrialization.

[0051] See also Figure 1 , Figure 1The cross-sectional view of a seed arrangement device of an embodiment of the present application is provided in the embodiment of the present application. The embodiment of the present application proposes a seed arrangement device, which includes a seed delivery mechanism 2 and a seed discharging mechanism 3. The seed delivery mechanism 2 includes a seed delivery wheel 21 and a first driving member 22. The circumferential surface of the seed delivery wheel 21 is provided with a plurality of seed delivery grooves 211. The first driving member 22 drives the seed delivery wheel 21 to rotate to drive the seed delivery grooves 211 to move. The seed discharging mechanism 3 includes a seed discharging wheel 31 and a second driving member 32. The seed discharging wheel 31 is arranged below the seed delivery wheel 21. The circumferential surface of the seed discharging wheel 31 is provided with a plurality of seed discharging sockets 311. The second driving member 32 drives the seed discharging wheel 31 to rotate to drive the seed discharging sockets 311 to move. Among them, the seed delivery wheel 21 delivers incoming seeds to the seed discharging sockets 311 through the seed delivery grooves 211, and the seed discharging wheel 31 arranges the seeds through the seed discharging sockets 311 and then outputs them.

[0052] According to the seed arrangement device of the embodiment of the present application, the first driving member 22 drives the seed delivery wheel 21 to rotate, and the seed delivery slot 211 receives the incoming seeds. As the seed delivery wheel 21 rotates, the seed delivery slot 211 transfers the received seeds to the seeding mechanism 3. The second driving member 32 drives the seeding wheel 31 to rotate, and the seeds transferred to the seeding mechanism 3 through the seed delivery slot 211 arrive at the seeding wheel 31 and enter the seeding socket 311. As the seeding wheel 31 rotates, the seeding socket 311 transports the seeds accommodated in the socket to the conveying mechanism 1. Through the continuous operation of the seed delivery mechanism 2 and the seeding mechanism 3, the incoming seeds are continuously and orderly arranged on the conveying mechanism 1. Through the cooperation of the seed delivery mechanism 2 and the seeding mechanism 3, the seed delivery mechanism 2 can feed the seeds to the seeding mechanism 3 in an orderly manner, and it is not easy to be suspended, stuck or unable to fall. The seeding effect is stable and the filling efficiency is improved.

[0053] See also Figure 1 In some embodiments, the seed arrangement device also includes a queuing box 4, a seed disturbance plate 5 and a seed brush 6. The seed wheel 31 is rotatably connected to the queuing box 4. The top end of the seed disturbance plate 5 is connected to the inner wall of the queuing box 4 and is located downstream of the seed delivery channel 41. The bottom end of the seed disturbance plate 5 is inclined toward the center of the queuing box 4 and abuts against the circumferential outer wall of the seed wheel 31.

[0054] In some embodiments, the seed delivery wheel 21 and the seed discharge wheel 31 are both rotatably connected to the queuing box 4 , and a seed delivery channel 41 is provided between the seed delivery wheel 21 and the queuing box 4 .

[0055] See also Figure 1 and Figure 2 , Figure 3 as well as Figure 4Specifically, a connection portion 51 is provided at one end of the seed disturbing plate 5, and a protrusion 52 corresponding to the seeding socket 311 is provided at the other end. The connection portion 51 of the seed disturbing plate 5 is connected to the seeding box, and the protrusion 52 of the seed disturbing plate 5 abuts against the seeding wheel 31. As the seeding wheel 31 rotates, the circumferential outer wall of the seeding wheel 31 and the seeding socket 311 successively generate an action force with the protrusion 52 of the seed disturbing plate 5. Under the combined action of the action force and the gravity of the seed disturbing plate 5, the seed disturbing plate 5 is driven to swing back and forth with the connection portion 51 as the center. In the process of the reciprocating swing of the seed disturbing plate 5, the seed disturbing plate 5 produces a disturbing effect on the seeds in the seed filling space 42.

[0056] It can be understood that in some embodiments, the connection portion 51 of the seed disturbing plate 5 is bent, and the angle between the connection portion 51 and the body of the seed disturbing plate 5 is ninety degrees. The side wall of the queuing box 4 is provided with a connecting groove 412, and the connection portion 51 of the seed disturbing plate 5 passes through the connecting groove 412 and overlaps in the connecting groove 412. In other embodiments, the connection portion 51 of the seed disturbing plate 5 is not limited to the above structure, and it can be movably connected with the queuing box 4, so that the seed disturbing plate 5 can swing back and forth under the action of external force.

[0057] It is understandable that, in some embodiments, the raised portion 52 of the seed disturbing plate 5 is in the shape of a convex block, and may also be set to other shapes, as long as it is correspondingly arranged for the seeding holes 311 and can swing with the rotation of the seeding wheel 31.

[0058] As the seeding wheel 31 rotates, the seeding wheel 31 has a toggling effect on the seed disturbing plate 5, and the seed disturbing plate 5 swings as the seeding wheel 31 rotates, that is, the seed disturbing plate 5 can generate a passive swing as the seeding wheel 31 rotates. It can be understood that in some other embodiments, an independent driving unit can be configured for the seed disturbing plate 5 to drive the seed disturbing plate 5 to actively move, and the rotational movement of the seed disturbing plate 5 can be set to swing, or it can be set to a rotating circular motion like the seeding wheel 31, which can disturb the seeds in the seed filling space 42.

[0059] After the seeds fall from the seed delivery wheel 21 , they fall onto the seed disturbance plate 5 . The seed disturbance plate 5 is tilted to guide the seeds to be filled into the seed placement holes 311 on the seed placement wheel 31 , and can also disturb the seeds in the seed filling space 42 .

[0060] The seed brush 6 is fixedly arranged in the queuing box 4, and the seed brush 6 is kept in contact with the circumferential outer wall of the seed wheel 31, and is used to brush away the excess seeds protruding from the surface of the seed wheel 31 in the seeding socket 311. Among them, the queuing box 4, the seed delivery wheel 21, the seed disturbance plate 5, the seed wheel 31 and the seed brush 6 enclose and construct the seed filling space 42. Through the above arrangement, the seeds delivered by the seed delivery wheel 21 can have a buffer space, and can be better disturbed in the seed filling space 42, and can guide the seeds to enter the seeding socket 311 of the seed wheel 31 more quickly.

[0061] See also Figure 5 and Figure 6 , Figure 5 A cross-sectional view of a seed delivery box 23 in a seed arrangement device according to an embodiment of the present application is shown. Figure 6 The schematic diagram of the structure of the seed delivery box 23 in the seed arrangement device of one embodiment of the present application is shown. In some other embodiments, the seed arrangement device includes a feeding box 7 and a seed delivery box 23, and the feeding box 7 is provided with a feeding end 71. The seed delivery box 23 is arranged above the queuing box 4, and the seed delivery box 23 is provided with a material inlet 46 for the feeding end 71 to extend into, and the seed delivery wheel 21 is rotatably connected to the seed delivery box 23, and the feeding end 71 abuts against the circumferential outer wall of the seed delivery wheel 21; the seed delivery box is provided with a feeding port 232, and the incoming seeds enter the queuing box 4 through the feeding port 232.

[0062] Specifically, the seed delivery box 23 is independent of the queuing box 4 and is located above the queuing box 4. The seed delivery box 23 is provided with a feeding channel 231 for feeding the seed delivery wheel 21. The seed delivery wheel 21 is arranged at the tail end of the feeding channel 231. With the rotation of the seed delivery wheel 21, the seeds transmitted through the feeding channel 231 enter the seed delivery groove 211 of the seed delivery wheel 21. A feeding port 232 is provided at the bottom of the seed delivery box 23. The seeds rotate with the seed delivery groove 211 to a position close to the feeding port 232, and fall out of the seed delivery box 23 from the feeding port 232 under the action of centrifugal force and its own gravity. A discharge inlet 410 connected to the seed filling space 42 is provided at the top of the seed delivery box 4, and the seeds enter the seed filling space 42 through the discharge inlet 410.

[0063] Specifically, in some embodiments, a seed brush 6 is also fixedly arranged in the seed delivery box 23, and the seed brush 6 is kept in contact with the circumferential outer wall of the seed delivery wheel 21, and is used to brush away the excess seeds protruding from the surface of the seed delivery wheel 21 in the seed delivery groove 211. This improves the consistency of the seed delivery amount of each seed delivery groove 211 of the seed delivery wheel 21.

[0064] See also Figure 1 and Figure 2In some embodiments, the first driving member 22 drives the seed delivery wheel 21 to rotate in a first direction. The second driving member 32 drives the seed delivery wheel 31 to rotate in a second direction, and the first direction is opposite to the second direction. Specifically, the first driving member 22 includes a first motor, the output shaft of the first motor is fixedly connected to the seed delivery wheel 21, and the first motor is started to drive the seed delivery wheel 21 to rotate. By controlling the rotation speed of the first motor, the feeding speed of the seed delivery wheel 21 can be controlled, that is, the speed at which the seed delivery wheel 21 delivers seeds to the seed filling space 42. The second driving member 32 includes a second motor, the output shaft of the second motor is fixedly connected to the seed delivery wheel 31, and the second motor is started to drive the seed delivery wheel 31 to rotate. By controlling the rotation speed of the second motor, the discharging speed of the seed delivery wheel 31 can be controlled, that is, the speed at which the seed delivery wheel 31 delivers seeds to the conveying mechanism 1. Under the cooperation of the first driving member 22 and the second driving member 32, the seed delivery wheel 21 and the seed discharging wheel 31 rotate in opposite directions, so that the seeds can be better disturbed by the interaction between their own gravity and the seed disturbing plate 5, and can more easily enter the seed discharging socket 311, thereby avoiding a large amount of accumulation in the seed filling space 42. In some embodiments, the feeding wheel rotates clockwise and the seed discharging wheel 31 rotates counterclockwise.

[0065] See also Figure 7 , Figure 7 Schematic diagram of the structure of the disturbance protrusion 314 in the seed arrangement device of one embodiment of the present application. In some embodiments, the circumferential surface of the seeding wheel 31 is provided with a plurality of disturbance protrusions 314, and one or both sides of the disturbance protrusion 314 extend toward the seeding socket 311, so as to guide the seeds on the circumferential surface of the seeding wheel 31 to the seeding socket 311.

[0066] Specifically, in some embodiments, the disturbance protrusion 314 is V-shaped, and the sharp end of the disturbance protrusion 314 faces the rotation direction of the seed wheel 31. The disturbance protrusion 314 is fixedly arranged between adjacent seeding holes 311, so that the circumferential outer wall of the seeding wheel 31 is uneven. During the rotation of the seeding wheel 31, the seeds on the surface of the seeding wheel 31 are disturbed, and the seeds between the two seeding holes 311 can be guided into the seeding holes 311 on both sides, so as to enhance the disturbance effect of the seeds in the seed filling space 42, thereby increasing the seed filling efficiency of the seeds in the seeding holes 311.

[0067] Specifically, in some embodiments, a rounded structure is provided at the edge of the seeding socket 311 so that the edge of the seeding socket 311 transitions smoothly with the outer wall of the seeding wheel 31 , further improving the seed filling efficiency of the seeding socket 311 .

[0068] It is understandable that the disturbance protrusion 314 can also be set to other features. As long as the circumferential surface of the seed wheel 31 can be made uneven, it can effectively disturb the seeds during the rotation of the seed wheel 31, increase the seed filling efficiency, and at the same time ensure that no seeds will remain in the seed filling area.

[0069] See also Figure 8 , Figure 8 The structure diagram of the partition plate 317 in the seed arrangement device of one embodiment of the present application is shown. In some embodiments, in order to improve the seed filling efficiency of the seeding socket 311, a plurality of partition plates 317 may be provided, and the partition plates 317 are fixedly provided above the seeding wheel 31, and the outer wall of the partition plates 317 is inclined to guide the seeds into the seeding socket 311, which can also improve the seed filling efficiency of the seeding socket 311.

[0070] See also Figure 1 In some embodiments, a pile detection component 43 is provided in the seed filling space 42, and the pile detection component 43 is provided in the seed filling space 42 for detecting the seed accumulation height in the seed filling space 42; the pile detection component 43 is communicated with the first driving member 22, and when the pile detection component 43 detects that the seed accumulation in the seed filling space 42 reaches a preset height, the first driving member 22 suspends operation.

[0071] Specifically, in some embodiments, the pile detection component 43 includes a photoelectric detector, which is arranged near the middle of the seed filling space 42. The photoelectric detector detects the seed accumulation height in the seed filling space 42. When the seed accumulation height reaches a preset height, the first driving member 22 is driven to suspend operation, so that the seed delivery wheel 21 stops rotating, that is, the seed delivery mechanism 2 stops the seed delivery work. Through the real-time detection of the seed accumulation height in the seed filling space 42 by the pile detection component 43, the seeds in the seed filling space 42 can be controlled to be kept below a certain preset height, so as to avoid a large amount of seeds from accumulating in the seed filling space 42, affecting the seeding work of the seeding mechanism 3, and ensuring the normal seeding work and seeding efficiency of the seeding equipment.

[0072] See also Fig. 9 , Fig. 9 A partial cross-sectional view of a seed arrangement device according to an embodiment of the present application. In some embodiments, a restraining spring sheet 44 is fixedly disposed in the queuing box 4, the restraining spring sheet 44 abuts against the circumferential outer wall of the seeding wheel 31, and the bottom end of the restraining spring sheet 44 extends downward, and is used to keep the seeds entering the seeding socket 311 in the seeding socket 311 before the seeding socket 311 reaches a preset position for releasing the seeds in the seeding socket 311.

[0073] Specifically, the restraining spring piece 44 includes a fixed section 441 and a restraining section 442 connected to the fixed section 441. The restraining section 442 is the bottom end of the restraining spring piece 44. The restraining section 442 is arc-shaped and fits tightly against the outer wall of the seeding wheel 31. The restraining spring piece 44 blocks the seeding socket 311 that has just been filled with seeds, preventing it from falling from the seeding socket 311 under the action of centrifugal force and gravity during the rotation of the seeding wheel 31, ensuring that the seeding wheel 31 can drive it to rotate to the lowest position and fall on the conveying mechanism 1 to finally form seeds on the conveying mechanism 1. The restraining spring piece 44 has a certain degree of flexibility, so that it can be applied to seeds of different sizes, and has a certain degree of versatility and inclusiveness.

[0074] See also Fig. 9 In some embodiments, the top of the constraint spring sheet 44 can be detachably fixedly connected to the side of the seed brush 6 away from the seed filling space 42. Specifically, a constraint mounting plate 4411 is provided at the fixed end of the constraint spring sheet 44, and the constraint mounting plate 4411 is fixed to the side of the seed brush 6 away from the seed filling space 42 by removing the bolt 4412.

[0075] See also Fig. 9 , Fig.10 and Fig.11 , Fig.10 A schematic diagram showing the structure of a cleaning plate 45 in a seed arrangement device according to an embodiment of the present application is shown. Fig.11 Another schematic diagram of the structure of the cleaning plate 45 in the seed arrangement device of one embodiment of the present application is shown. In some embodiments, the circumferential outer wall of the seeding wheel 31 is provided with a cleaning annular groove 318 passing through the seeding socket 311 along its circumference. A cleaning plate 45 is fixedly provided in the queuing box 4, and the cleaning plate 45 is provided with cleaning teeth 451 extending into the cleaning annular groove 318. The cleaning teeth 451 are used to make the seeds retained in the seeding socket 311 escape when the seeding socket 311 passes through.

[0076] Specifically, the restraining spring sheet 44 is arranged on one side of the seeding wheel 31, and the cleaning plate 45 is arranged on the other side opposite to the seeding wheel 31. One end of the cleaning plate 45 is fixed on the inner wall of the queuing box 4, and the other end is bent and provided with cleaning teeth 451 extending toward the cleaning annular groove 318. Since the cleaning annular groove 318 passes through the seeding socket 311, as the seeding wheel 31 rotates, the seeding socket 311 passes through the cleaning teeth 451 in sequence, and the cleaning teeth 451 can remove the seeds remaining in the seeding socket 311.

[0077] The seeding wheel 31 drives the seeding socket 311 to rotate, and the seeding socket 311 is filled with seeds in the seed filling space 42; as the seeding wheel 31 continues to rotate, after the seeding socket 311 leaves the seed filling space 42, the seeding socket 311 rotates to abut against the restraining spring piece 44, and the seeds are enclosed in the seeding socket 311; as the seeding wheel 31 continues to rotate, the seeding socket 311 carrying the seeds rotates to the lowest position and separates from the restraining spring piece 44, and the seeding socket 311 is closed. The seeds in the seeding socket 311 fall onto the conveying mechanism 1 below and are transported to the next station by the conveying mechanism 1; the seeding wheel 31 continues to rotate, and the seeding socket 311 rotates with the seeding wheel 31 to the side of the seeding wheel 31 where the cleaning plate 45 is set, and the cleaning plate 45 abuts against the cleaning ring groove 318. If there are still residual seeds in the seeding socket 311, the residual seeds can be swept away, and the seeds stuck in the seeding socket 311 that cannot fall can be cleared, so that the seeds fall onto the conveying mechanism 1. The seeding socket 311 that has been cleared by the cleaning plate 45 rotates to the seed filling space 42 above as the seeding wheel 31 continues to rotate, and is filled with seeds again. The seeding wheel 31 is formed to fill, constrain, discharge, clear and fill again, and so on.

[0078] See also Figure 1 and Fig. 9 In some embodiments, the feeding end 71 and the inner wall of the queuing box 4 are enclosed to form the incoming material channel 47. Specifically, the seeds can be poured into the feeding box 7, and the seeds accumulated in the feeding channel can be taken by the seed feeding groove 211 as the seed feeding wheel 21 rotates. The first driving member 22 drives the seed feeding wheel 21 to rotate clockwise, driving the seed feeding groove 211 containing the seeds to rotate to the side close to the seed feeding channel 41, and then continues to rotate downward. The seeds in the seed feeding groove 211 enter the seed filling space 42 under the action of centrifugal force and its own gravity, and the seed filling space 42 plays a buffering role.

[0079] In some embodiments, the seed arrangement device further includes a conveying device, which includes a conveying belt 11, and the seeding wheel 31 arranges the seeds through the seeding holes 311 and outputs them to the conveying belt 11, so that the seeds are arranged in order on the conveying belt 11, and the conveying belt 11 conveys the orderly arranged seeds to the target position.

[0080] See also Figure 2In some embodiments, the conveying device includes a conveyor belt 11, and the conveyor belt 11 is provided with a plurality of rows of belt holes 111, and each row of belt holes 111 is opposite to the axial position of the seeding holes 311 of the seeding wheel 31. The distribution distance of the seeding holes 311 in the axial direction of the seeding wheel 31 matches the distribution distance of the belt holes 111 on the conveyor belt 11. By controlling the driving speed of the second driving member 32, the rotation speed of the seeding wheel 31 can be controlled to control the seeding speed of the seeding wheel 31. At the same time, the moving speed of the conveyor belt 11 is synchronously controlled, so that the seeding wheel 31 and the conveyor belt 11 are relatively stationary at the intersection, and the seeding holes 311 of the seeding wheel 31 correspond to the belt holes 111 on the conveyor belt 11 below each time the seeds are discharged. The seeds can be accurately, stably, orderly and regularly arranged in the belt holes 111 on the conveyor belt 11, which improves the seeding quality and is more convenient for the identification and sorting work of the next process. The whole process can be continuously operated uninterruptedly, and the efficiency is greatly improved. If there are multiple seeds in one seeding hole 311, the seeds will still be sent away by the conveyor belt 11 to avoid accumulation. It is understandable that the conveyor belt 11 may not be perforated, and the seeds can be arranged on the conveyor belt 11 only by the seeding holes 311 on the seeding wheel 31.

[0081] See also Figure 2 In some embodiments, the queuing box 4 is provided with a discharge chute 48, and the discharge chute 48 and the conveying mechanism 1 are enclosed to form a discharge channel.

[0082] See also Fig.10 and Fig.11 In some embodiments, a plurality of dividing channels 411 are further provided in the queuing box 4, one end of the dividing channel 411 is provided corresponding to the seeding socket 311, and the other end is connected to the discharge channel. Specifically, the dividing channel 411 includes two relatively arranged dividing plates 4111, and the end of the dividing plate 4111 close to the discharge channel is inclined inward, so that the end of the dividing channel 411 close to the discharge channel is retracted. The seeds that fall from the seeding socket 311 to the conveyor belt 11 enter the dividing channel 411 as the conveyor belt 11 moves, and under the guidance of the inclined dividing plate 4111, they approach the end of the dividing channel 411 close to the discharge channel, and are finally introduced into the discharge channel by the dividing channel 411, and then discharged from the discharge channel. After the division and guidance of the dividing channel 411, the position of the seeds with deviations in the queue can be adjusted, the neatness of the queue is improved, and the subsequent sorting work is convenient.

[0083] In some embodiments, the dividing plate 4111 is fixedly connected to the cleaning plate 45, and a blocking plate 4112 is further provided at the top of the end of the dividing channel 411 near the discharge channel. The top of the blocking plate 4112 is fixedly connected to the cleaning plate 45, and the bottom is at a certain distance from the surface of the conveyor belt 11. The blocking plate 4112 has a blocking effect in the vertical direction, which can further enhance the dividing channel 411's effect of dividing and guiding seeds.

[0084] See also Fig.12 , Fig.12 This is a schematic diagram of the structure of the queuing box 4 in the seed arrangement device of one embodiment of the present application. The queuing box 4 is elastically connected to the conveying mechanism 1, so that the queuing box 4 can move relative to the conveying mechanism 1 in response to external force. The discharge channel drives the queued seeds out of the queuing box 4 through the conveyor belt 11. The queuing box 4 is elastically connected to the conveying mechanism 1, so that the discharge channel is not locked, to prevent the seeding wheel 31 from being directly squeezed by the conveyor belt when there are multiple seeds in the seeding socket 311, the seeds are too large, or there are foreign objects, etc., to avoid crushing the seeds or damaging the seeding equipment.

[0085] Specifically, in some embodiments, a first compression spring 49, a second compression spring 491 and an equal height screw 492 are connected between the queuing box 4 and the frame 112 of the conveying mechanism 1. The first compression spring 49 is sleeved on the outside of the equal height screw 492, and the second compression spring 491 is connected between the frame 112 and the queuing box 4. A positioning pin 493 is fixedly arranged on the frame 112, the top of the positioning pin 493 is vertically upward and is provided with a sharp portion, and a positioning hole 494 for inserting the positioning pin 493 is provided at the bottom of the queuing box 4. The queuing box 4 is limited by the positioning pin 493 and the positioning hole 494, so that the queuing box 4 can only move slightly in the vertical direction. The second compression spring 491 mainly bears the weight of the queuing box 4 to prevent crushing of seeds or damage to the conveying mechanism 1. The first compression spring 49 ensures that the queuing box 4 can be quickly reset after being lifted up, so as to realize the adaptive floating of the queuing box 4 in the vertical direction of the conveying mechanism 1.

The second motor can be configured as a reduction stepping motor.

[0088] See also Fig.13 and Fig.14 , Fig.14 The cross-sectional view of the seeding wheel 31, the transmission shaft 312 and the quick release handle 313 in the seed arrangement device of one embodiment of the present application. The transmission shaft 312 is clamped with one end of the seeding wheel 31. Specifically, the end of the seeding wheel 31 is provided with a first clamping protrusion 315, and the end of the transmission shaft 312 is provided with a first clamping groove 3123. The first clamping protrusion 315 can be inserted into the first clamping groove 3123 along the axial direction of the seeding wheel 31 and clamped with the first clamping groove 3123. The other end of the transmission shaft 312 is clamped with the quick release handle 313. Specifically, the end of the transmission shaft 312 away from the first clamping protrusion 315 is provided with a second clamping groove 316, and the quick release handle 313 is provided with a second clamping protrusion 3131. The second clamping protrusion 3131 can be inserted into the second clamping groove 316 along the axial direction of the seeding wheel 31 and clamped with the second clamping groove 316. The quick-release handle 313 is rotatably connected to the queuing box 4. When the first motor is started, the transmission shaft 312 is driven to rotate through the coupling 3121, and the transmission shaft 312 drives the seeding wheel 31 to rotate. When the seeding wheel 31 needs to be removed from the seeding box, it is only necessary to first remove the quick-release handle 313 from the queuing box 4, and then move the seeding wheel 31 so that the first clamping protrusion 315 and the first clamping groove 3123 are separated from the casing, which is convenient for quick and convenient maintenance of the seeding wheel 31, and replacement of the seeding wheel 31 with different seeding socket 311 sizes to adapt to seeds of different shapes / sizes.

[0090] Specifically, in some embodiments, the jam detection assembly 33 includes a photoelectric sensor 331 and a grating disc ruler 332. The grating disc ruler 332 is fixedly mounted on the transmission shaft 312 and is coaxially arranged with the transmission shaft 312. The grating disc ruler 332 can rotate with the transmission shaft 312. The photoelectric sensor 331 is fixed in the queuing box 4 and can detect the grating disc ruler 332. The rotation speed signal of the seeding wheel 31 is determined by the rotation speed signal of the grating disc ruler 332.

[0091] In some embodiments, the rotation position signal of the seeding wheel 31 is determined by the rotation position signal of the grating disc ruler 332. If the transmission shaft 312 rotates normally, the grating disc ruler 332 can periodically trigger the photoelectric sensor 331. If the trigger signal is not received within the specified time, it is determined that the transmission shaft 312 is stuck, that is, the seeding wheel 31 is stuck. The rotation position detection of the seeding wheel 31 is by opening a plurality of grating grooves in the radial direction on the grating disc ruler 332, and the grating grooves correspond to the seeding holes 311 one by one, that is, each time a grating signal is detected, a row of seeds is arranged on the conveyor belt 11.
