Description

Technical Field

[0001] This invention relates to the field of alfalfa auxiliary pollination equipment technology, specifically a high-efficiency alfalfa pollinator. Background Technology

[0002] Alfalfa is a high-quality protein feed with wide adaptability, high yield, good quality, and soil improvement properties. It has good economic and ecological benefits and plays an important role in the strategic adjustment of agricultural industrial structure and ecological environment construction. It has been cultivated in my country for more than 2,000 years and is distributed in Northwest, North, and Northeast China. It is also the forage grass with the largest cultivation area in my country. As of the end of 2021, the Ministry of Agriculture and Rural Affairs had approved 239 new leguminous forage grass varieties, involving 69 species. Among them, the genus alfalfa has the most varieties, including 7 species and 114 varieties. Alfalfa is a cross-pollinated plant with self-sterile or very low self-compatibility. Due to its unique flower structure and pollination requirements, pollination has always been one of the important factors restricting its seed yield in my country.

[0003] Artificial pollination refers to the technique of transferring plant pollen to the stigma using artificial methods to improve seed yield or to directionally alter the plant species. Artificial pollination is of great help to scientific research and agricultural planting. The tools commonly used for artificial pollination are small brushes. The pollinator picks up the pollen and then touches the brush head to the stamen, gently smearing it to achieve the pollination effect. However, the pollination method of picking up the pollen with a brush and then smearing it can easily lead to uneven pollination of the stamen, or the brush may irritate the stamen if the smearing force is not controlled precisely, thus affecting the pollination effect and resulting in less than ideal pollination results. Therefore, we propose a high-efficiency alfalfa pollinator. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention by adopting the above technical solution are as follows:

[0016] 1. The present invention, through the setting of the irregularly shaped block, enables the motor to provide power to drive the irregularly shaped block to rotate during pollination, which squeezes the upper connecting plate and the lower connecting block, causing the connecting plate and the connecting block to move in opposite directions. At this time, the spring is in a stretched state. When the irregularly shaped block rotates 180°, the squeezing of the connecting plate and the connecting block is released, and the spring returns to its original position. During the return process, the vibration of the spring causes the filter screen connected to the connecting block to vibrate, thereby shaking off the pollen on the filter screen and performing the pollination operation evenly.

[0017] 2. In this invention, the second motor drives the telescopic rod and the cross to rotate, causing multiple fixed frames on the cross to move accordingly. Multiple sliding blocks on the rear side of the fixed frames further reinforce the connection between the fixed frames and the sleeve. Because the fixed frames are equipped with multiple soft brushes, the soft brushes move synchronously as the fixed frames move, applying physical external force to the alfalfa to open it and facilitate pollen collection.

[0018] 3. The present invention, through the setting of the sleeve, can directly cover the entire inflorescence when collecting pollen from alfalfa, and collect or pollinate the flowers on the entire inflorescence at the same time. It can prevent pollen from being ejected during pollen collection, which is highly efficient. In addition, in combination with multiple suction ports and spray nozzles, the pollen residue in the soft brush and sleeve is reduced.

[0019] Other advantages, objectives and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be learned from the practice of the invention.

[0028] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0029] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Please see the appendix Figure 1 -Appendix Figure 7 The present invention discloses a high-efficiency alfalfa pollinator, comprising a handle tube 1, a protective cover 2 fixedly connected to the bottom left side of the handle tube 1, a sleeve 3 fixedly connected to the bottom side of the protective cover 2, a powder spraying mechanism provided on the top side of the sleeve 3, a powder collection mechanism provided on the inner side of the sleeve 3, a mounting base 29 fixedly connected to the middle side of the outer wall of the handle tube 1, a storage box 30 fixedly connected to the right end of the handle tube 1, two shoulder straps 33 provided on the left side of the storage box 30, a handle 31 fixedly connected to the middle of the top side of the storage box 30, and a box plug 32 provided at the rear end of the top side of the storage box 30.

[0031] The powder spraying mechanism includes a filter screen 4, which is located on the top side inside the sleeve 3. Connecting blocks 5 are fixedly connected to both the left and right sides of the filter screen 4. A fixed column 6 is slidably connected to the middle side inside the connecting block 5. A nut 7 is threadedly connected to the top of the fixed column 6. A connecting plate 8 is slidably connected to the top outer wall of the fixed column 6. The nut 7 is located above the connecting plate 8. One end of a telescopic column 9 is fixedly connected to the front and rear sides of the two connecting plates 8. The other end of the telescopic column 9 is fixedly connected to the top side of the connecting block 5. A spring 10 is provided on the outside of the telescopic column 9. The two ends of the spring 10 are fixedly connected to the adjacent surfaces of the connecting block 5 and the connecting plate 8, respectively. A motor 11 is fixedly connected to the left side of the top side of the sleeve 3. A shaped block 12 is fixedly connected to the drive end of the motor 11. The shaped block 12 is located between the left connecting block 5 and the connecting plate 8.

[0032] In embodiment one, the powder collection mechanism includes a second motor 14. The top side of the second motor 14 is fixedly connected to the bottom left side of the holding tube 1. The drive end of the second motor 14 is fixedly connected to the top end of the telescopic rod 13. The bottom end of the telescopic rod 13 passes through the center of the filter screen 4. The bottom end of the telescopic rod 13 is fixedly connected to a cross 15. The bottom sides of the multiple outer ends of the cross 15 are all fixedly connected to a fixing frame 16. The side of the fixing frame 16 away from the sleeve 3 is fixedly connected to a multiple soft brush 18. The side of the fixing frame 16 close to the sleeve 3 is fixedly connected to a multiple sliding block 17. The inner wall of the sleeve 3 is provided with a multiple sliding groove. The multiple sliding blocks 17 and the multiple sliding grooves are arranged in a one-to-one correspondence.

[0033] Specifically, motor 14 drives telescopic rod 13 and cross 15 to rotate, causing multiple fixing brackets 16 on cross 15 to move accordingly. Multiple sliding blocks 17 on the rear side of fixing bracket 16 further reinforce the connection with sleeve 3. Because multiple soft brushes 18 are provided on fixing bracket 16, the soft brushes 18 move synchronously while fixing bracket 16 moves, applying physical external force to alfalfa to open it.

[0034] In embodiment two, an annular tube 19 is provided on the inner middle side of the sleeve 3, and an annular tube 21 is provided on one side of the annular tube 19. The annular tube 21 and the annular tube 19 are arranged crosswise. Multiple nozzles 20 are fixedly connected to the side of the annular tube 19 near the center of the sleeve 3, and multiple suction ports 22 are fixedly connected to the side of the annular tube 21 near the center of the sleeve 3. One end of the powder suction tube 23 is fixedly connected to the outer wall of the annular tube 21, and the other end of the powder suction tube 23 passes through the two ends of the holding tube 1 and is fixedly connected to the drive end of the powder suction pump 24. The powder suction pump 24 is fixedly connected to the inner wall of the storage box 30. One end of the air blowing pipe 27 is fixedly connected to one side of the outer wall of the ring pipe 19. The other end of the air blowing pipe 27 passes through the left end of the holding pipe 1 and is fixedly connected to the drive end of the air blowing pump 28. The air blowing pump 28 is fixedly connected to the inner middle side of the mounting base 29. A pollination pipe 25 is provided in the inner middle side of the holding pipe 1. The left end of the pollination pipe 25 passes through the left side of the holding pipe 1 and is located above the filter screen 4. The right end of the pollination pipe 25 is fixedly connected to the drive end of the pneumatic powder spraying pump 26. The pneumatic powder spraying pump 26 is fixedly connected to the inner wall of the storage box 30. The pneumatic powder spraying pump 26 is located to the right of the powder suction pump 24.

[0035] Specifically, the airflow generated by the air pump 28 applies external force to the alfalfa, causing the alfalfa flowers to shake and open. After opening, the airflow causes the pollen to fly out into the sleeve 3. Then, the pollen is collected by the suction pump 24 through the suction pipe 23 and multiple suction ports 22, and enters the storage box 30. Since the soft brush 18 moves with the fixed frame 16, when the soft brush 18 passes the nozzle 20, the pollen on the surface of the soft brush 18 will be blown off, and when the soft brush 18 passes the suction port 22, the pollen on the surface of the soft brush 18 will be sucked away, thus avoiding the presence of residual pollen on the soft brush 18.

[0036] In embodiment three, multiple soft brushes 18, nozzles 20, and suction ports 22 are arranged longitudinally in an alternating pattern. The length of a single soft brush 18 is one-fifth of the diameter of the sleeve 3. Multiple buttons are provided on the top side of the mounting base 29, and these buttons correspond to the motor 11, the powder suction pump 24, the pneumatic powder spraying pump 26, and the air blowing pump 28, respectively.

[0037] Specifically, the mounting base 29 enables the motor 11, the powder suction pump 24, the pneumatic powder spraying pump 26, and the air blowing pump 28 to be controlled in a coordinated manner. The staggered longitudinal arrangement of multiple soft brushes 18, nozzles 20, and suction ports 22 prevents residual pollen from remaining in the soft brushes 18 and the sleeve 3.

[0038] Working principle:

[0039] Working principle: When collecting pollen, hold the handle tube 1 and place the sleeve 3 over the alfalfa flower. Then, activate the air pump 28, motor 14, and pollen pump 24 sequentially via the buttons on the mounting base 29. Motor 14 drives the telescopic rod 13 and cross 15 to rotate, causing multiple fixing brackets 16 on the cross 15 to move accordingly. Multiple sliding blocks 17 on the rear side of the fixing brackets 16 further reinforce the connection between them and the sleeve 3. Because the fixing brackets 16 are equipped with multiple soft brushes 18, the soft brushes 18 move synchronously as the fixing brackets 16 move, applying physical force to the alfalfa and causing it to be pollinated. During the opening process, the airflow generated by the air pump 28 simultaneously applies external force to the alfalfa, causing the alfalfa flowers to shake and open. After opening, the airflow causes the pollen to fly out into the sleeve 3. Then, the pollen is collected in the sleeve 3 by the suction pump 24 through the suction tube 23 and multiple suction ports 22. The pollen is then placed into the storage box 30. Since the soft brush 18 moves with the fixed frame 16, when the soft brush 18 passes the nozzle 20, the pollen on the surface of the soft brush 18 will be blown off. When the soft brush 18 passes the suction port 22, the pollen on the surface of the soft brush 18 will be sucked away, thus avoiding the presence of residual pollen on the soft brush 18.

[0040] During pollination, the pneumatic powder spraying pump 26 and motor 11 are activated sequentially via buttons on mounting base 29 to transport the pollen collected in storage box 30 into pollination tube 25, where it falls onto filter screen 4. At this time, motor 11 provides power to rotate the irregular block 12, which compresses the upper connecting plate 8 and the lower connecting block 5, causing them to move in opposite directions. Spring 10 is in a stretched state. After the irregular block 12 rotates 180°, the compression of connecting plate 8 and connecting block 5 is released, and spring 10 resets the filter screen 4 connected to connecting block 5 due to the vibration of spring 10. This causes the pollen on filter screen 4 to fall evenly onto the alfalfa flowers in sleeve 3 below, completing the pollination operation. The entire workflow ends here.
