[0035] Specifically, the lifting frame 1 can be installed on the external vehicle body, and the lifting frame 1 is lifted to an appropriate height by the external general control device, so that it is sleeved at the parent corn ear, and then the bottom plate 6 is driven to move oppositely by controlling the electric push rod 7 to realize the closure of the bottom of the sleeve 2, further open the motor 10 and the air extractor 3, and automatically collect the parent corn pollen. The bottom plate 6 moves oppositely for a period of time, and then the air guide assembly one 8 extrudes the air bag one 83, further transports the gas generated by the extruded air bag one 83 to the expansion block 9 through the external air guide pipe, and then realizes flexible clamping of different root corn stalks, and also realizes efficient sealing of the sleeve 2, avoids the parent corn pollen from spilling into the air, and affects the health of the operator.

[0037] Specifically, the bottom plate 6 moves oppositely for a period of time and contacts the sliding rod one 82, further driving the sliding rod one 82 to slide in the fixed column one 81, and further compressing the air bag one 83.

[0038] Please refer to the accompanying drawings Figure 5 and the accompanying drawings Figure 6 , the inside of the sleeve 2 is fixedly provided with the motor 10, the driving end of the motor 10 is connected with the umbrella wheel one 11, the tooth end of the umbrella wheel one 11 is meshingly connected with the umbrella wheel two 12, the inside of the umbrella wheel two 12 is fixedly connected with the rotating column one 13, the end of the rotating column one 13 away from the umbrella wheel two 12 is fixedly connected with the cloth strip 15, and the tooth end of the umbrella wheel one 11 is meshingly connected with the umbrella wheel three 14; the outer wall of the umbrella wheel two 12 is rotatably connected in the inside of the sleeve 2, the outer wall of the rotating column one 13 is rotatably connected in the inside of the sleeve 2, the outer wall of the umbrella wheel three 14 is rotatably connected in the inside of the sleeve 2, the end of the umbrella wheel three 14 away from the umbrella wheel one 11 is fixedly connected to the outer wall of the cloth strip 15, and the outer wall of the rotating column one 13 is rotatably connected in the inside of the umbrella wheel three 14.

[0039] Specifically, when the motor 10 is running, the driving end of the motor 10 and the umbrella wheel one 11 are fixed, which drives the umbrella wheel one 11 to rotate, further drives the umbrella wheel two 12 and the umbrella wheel three 14 connected by the tooth end to rotate in the forward and reverse directions. When the umbrella wheel two 12 rotates, the umbrella wheel two 12 and the rotating column one 13 are fixed, which drives the rotating column one 13 and the umbrella wheel two 12 to rotate in the same direction, further drives the cloth strip 15 fixed on the outer wall of the rotating column one 13 to rotate. When the umbrella wheel three 14 rotates, it drives the cloth strip 15 fixed on the outer wall of the umbrella wheel three 14 to rotate in the same direction. Through the reverse rotation of the cloth strip 15, the parent corn tassel is flexibly beaten in the forward and reverse directions during the collection of the parent corn pollen, so that the parent corn pollen can be efficiently and completely shed, and the collection efficiency of the parent corn pollen is improved.

[0040] Please refer to the accompanying drawings Figure 6 and the accompanying drawings Figure 7 , the inside of the sleeve 2 is fixedly provided with a filter plate 16, the top end of the umbrella wheel two 12 is provided with a vibration assembly 17, the vibration assembly 17 comprises a hammer 175, the outer wall of the hammer 175 is attached with a fixed frame one 176, the outer wall of the fixed frame one 176 is fixedly connected to the inner wall of the sleeve 2; the vibration assembly 17 further comprises a rotating block one 171, the inside of the rotating block one 171 is fixedly provided at the top end of the umbrella wheel two 12, the outer wall of the rotating block one 171 is attached with a transmission block 172, the inside of the transmission block 172 is slidably connected with a fixed rod 173, one end of the fixed rod 173 away from the rotating block one 171 is fixedly provided in the inside of the sleeve 2, one end of the transmission block 172 away from the rotating block one 171 is fixedly provided with an elastic member one 174, one end of the elastic member one 174 away from the rotating block one 171 is fixedly provided on the inner wall of the sleeve 2, the outer wall of the hammer 175 is fixedly connected to the inside of the transmission block 172.

[0041] Specifically, when the parachute wheel 12 rotates, the fixing action of the parachute wheel 12 and the rotating block 171 causes the rotating block 171 to rotate. After rotating for a period of time, the protrusion of the rotating block 171 will contact the transmission block 172, further causing the transmission block 172 to slide on the outer wall of the fixed rod 173. At the same time as sliding, it cooperates with the sleeve 2 to compress the elastic element 174. When the transmission block 172 slides, the fixing action of the transmission block 172 and the hammer 175 causes the hammer 175 to move so that it is in contact with the fixed rod 173. When the fixed frame 176 disengages, the rotating block 171 continues to rotate. When the rotating block 171 disengages from the transmission block 172, the elastic element 174 releases its own elastic force to reset the transmission block 172 and the hammer 175, further causing the hammer 175 to collide with the fixed frame 176. This results in a slight vibration of the entire device when collecting pollen from the male parent corn, preventing the pollen from adhering to the inner wall of the device and causing incomplete collection, which would further affect the normal operation of subsequent corn seed production.

[0042] Please see the appendix Figure 7 -Appendix Figure 9 An air guide assembly 18 is mounted on the upper surface of the transmission block 172. The air guide assembly 18 includes an airbag 183. The airbag 183 is fixedly connected to a piston tube 19 through an external air guide pipe. The outer wall of the piston tube 19 is fixedly disposed inside the sleeve 2. A drive assembly 20 is installed inside the piston tube 19. The drive assembly 20 includes a fixing frame 203. Multiple cleaning plates 21 are fixedly connected to the outer wall of the fixing frame 203. In the initial state, the distance between the cleaning plates 21 and the filter plate 16 increases sequentially. The cleaning plates 21 are slidably connected inside the sleeve 2. The lower surface of the cleaning plates 21 is attached to the upper surface of the filter plate 16. An elastic element 22 is fixedly disposed on the side of the cleaning plate 21 away from the piston tube 19. The end of the elastic element 22 away from the cleaning plate 21 is fixedly disposed on the sleeve. The inner wall of sleeve 2; the air guiding assembly 218 also includes a fixing post 2181, the outer wall of the fixing post 2181 is fixedly disposed inside the sleeve 2, the inner wall of the fixing post 2181 is slidably connected to a sliding block 182, the lower surface of the sliding block 182 is fixedly connected to the upper surface of the transmission block 172, the outer wall of the sliding block 182 is attached to the outer wall of the airbag 2183, and the airbag 2183 is installed inside the fixing post 2181; the drive assembly 20 also includes a piston rod 201, the outer wall of the piston rod 201 is slidably connected to the inside of the piston tube 19, one end of the piston rod 201 is fixedly connected to the inside of the fixing bracket 203, and the other end of the piston rod 201 is fixedly disposed with an elastic element 202, the end of the elastic element 202 away from the piston rod 201 is fixedly disposed inside the piston tube 19.

[0043] Specifically, when the transmission block 172 moves, the fixed action of the transmission block 172 and the sliding block 182 causes the sliding block 182 to slide inside the fixed post 181. Simultaneously, the sliding block 182, in conjunction with the fixed post 181, compresses the airbag 183. The gas generated by compressing the airbag 183 is then transported to the piston tube 19 through an external air pipe, thereby pushing the internal piston rod 201 to slide. Simultaneously, the piston rod 201, in conjunction with the piston tube 19, stretches the elastic element 202. As the piston rod 201 slides, it... The fixing effect of the fixing frame 203 will cause the fixing frame 203 to slide inside the sleeve 2, which will further drive the cleaning plate 21 to slide on the upper surface of the filter plate 16. This will achieve the effect of automatically cleaning the filter holes of the filter plate 16 while collecting and filtering the male corn pollen, thus avoiding the filter holes of the filter plate 16 from becoming clogged and preventing the male corn pollen from being extracted normally. At the same time, the distance between each cleaning plate 21 and the filter hole in the filter plate 16 will increase sequentially, thus avoiding the cleaning plate 21 cleaning the filter holes in the filter plate 16 at the same time, which would prevent the extraction of male corn pollen from being obstructed.

[0044] Please see the appendix Figure 10 A connecting block 24 is fixedly connected to the lower surface of the lifting frame 1. A rotating column 25 is rotatably connected inside the connecting block 24. A rotating block 26 is fixedly connected to the bottom end of the rotating column 25. A connecting block 23 is attached to the upper surface of the rotating block 26. The outer wall of the connecting block 23 is fixedly connected to the outer wall of the collecting cylinder 4. Multiple sliding rods 28 are slidably connected inside the connecting block 24. The bottom end of the sliding rod 28 is attached to the upper surface of the connecting block 23. An elastic element 4 27 is fixedly provided on the outer wall of the sliding rod 28. The end of the elastic element 4 27 away from the connecting block 23 is fixedly provided on the lower surface of the connecting block 24.

[0045] Specifically, the connecting block 23 has a hole inside, and the size of the hole is adapted to the rotating block 26. In the initial state, the rotating block 26 and the hole are misaligned and the sliding rod 28 is in contact with the connecting block 23. At this time, the elastic element 27 is in a compressed state. The elastic element 27 is used to enhance the stability of the fit between the connecting block 23 and the rotating block 26. The elastic element 174, elastic element 202, elastic element 32 and elastic element 27 can be steel leaf springs, coil springs, torsion bar springs, rubber springs, etc., preferably coil springs. When it is necessary to disassemble the collecting cylinder 4, the rotating block 26 is rotated to align with the hole in the connecting block 23, thereby removing the limitation on the connecting block 23 and further removing the limitation and fixation on the collecting cylinder 4, which facilitates the operator to quickly disassemble and assemble the collecting cylinder 4.

[0046] Work process: When the motor 10 is working, it drives the parasol wheel 11 to rotate, which in turn drives the parasol wheels 12 and 14 meshing with it to rotate in both directions. When the parasol wheel 12 rotates, it drives the rotating column 13 to rotate synchronously in the same direction, which in turn causes the cloth strip 15 on the outer wall of the rotating column 13 to rotate. The parasol wheel 14 drives the cloth strip 15 on its outer wall to rotate synchronously in the same direction. Through the reverse rotation of the cloth strip 15, the ear of flowers is gently patted in both directions when collecting pollen from the male parent corn, so that the pollen can be efficiently and completely removed, thus improving the pollen collection efficiency.

[0047] When the umbrella wheel 12 rotates, it drives the rotating block 171 to rotate synchronously. When the protrusion of the rotating block 171 contacts the transmission block 172, it pushes the transmission block 172 to slide along the outer wall of the fixed rod 173, further compressing the elastic element 174. At the same time, it drives the hammer 175 to move and separate from the fixed frame 176. When the rotating block 171 and the transmission block 172 are no longer in contact, the elastic element 174 releases its own elastic force to drive the transmission block 172 and the hammer 175 to reset. This further causes the hammer 175 to collide with the fixed frame 176 and generate vibration, thereby preventing pollen from adhering to the inner wall of the device, ensuring thorough pollen collection, and ensuring the normal operation of subsequent seed production.

[0048] When the transmission block 172 moves, it drives the sliding block 182 to slide within the fixed column 181, further compressing the airbag 183. The gas generated by the compressed airbag 183 is then transported to the piston tube 19 through the external air guide pipe, further pushing the piston rod 201 to slide and stretching the elastic element 202. When the piston rod 201 slides, it drives the fixed frame 203 to move synchronously, further driving the cleaning plate 21 to slide on the upper surface of the filter plate 16. This achieves automatic cleaning of the filter holes of the filter plate 16 during pollen collection and filtration, preventing the filter holes from becoming clogged. Furthermore, by increasing the distance between each cleaning plate 21 and the filter holes of the filter plate 16 sequentially, it avoids the effect of pollen extraction being obstructed when the cleaning plates 21 clean the filter holes simultaneously.

[0049] In the initial state, the rotating block 26 is misaligned with the hole, and the sliding rod 28 is in contact with the connecting block 23. At this time, the elastic element 27 is in a compressed state, which improves the stability of the fit between the connecting block 23 and the rotating block 26. When disassembling the collection cylinder 4, the rotating block 26 is rotated to align with the hole in the connecting block 23, which releases the limiting fixation on the connecting block 23 and the collection cylinder 4, thereby facilitating the operator to quickly disassemble and assemble the collection cylinder 4.
