[0037] After the present invention has the windproof function, it is necessary to carry out pollination in the windproof environment, and the key link in the pollination operation is the pollination step; Figure 5 , which is a schematic diagram of the installation structure of the pollen collecting mechanism. It can be seen from the figure that the pollen collecting mechanism is installed above the top cover 5. The pollen collecting mechanism is used to collect alfalfa pollen. The present invention further designs a pollen collecting mechanism, and the specific structure is as follows.

[0038] Specifically, by combining Figure 5-6 ,in, Figure 6The schematic diagram of the partial assembly structure of the powder collecting mechanism is shown. It can be seen from the above two figures that the powder collecting mechanism includes an annular belt conveyor 11 (for example, the model used can be JL-005, which will not be described here), and the annular belt conveyor 11 is fixedly connected to the top cover 5 by a hanger 12; a carrying plate 13 is fixedly connected to the conveyor belt of the annular belt conveyor 11, and an electric telescopic cylinder 14 is provided below the carrying plate 13 (the existing product can be directly used, which will not be described here); the output end of the electric telescopic cylinder 14 is connected to the carrying plate 13 by a The connection is fixed by welding, and the back of the electric telescopic cylinder 14 is fixedly connected with a powder bunker 15, one side of the powder bunker 15 is installed with an exhaust fan 16, the air outlet end of the exhaust fan 16 is fixedly connected to the powder bunker 15 and communicated with the inner cavity of the powder bunker 15, the exhaust nozzle of the exhaust fan 16 is used to face the pollen of alfalfa; the lower end of the powder bunker 15 is provided with a discharge port 17, the discharge port 17 is installed with a discharge unit, the discharge unit is used to control the discharge of pollen in the powder bunker 15, and the more specific structure of the discharge unit is as follows.

[0039] Further integration Figure 6-8 ,in, Figure 7 The diagram shows the exploded structure of the powder collecting mechanism. Figure 8The exploded structure schematic diagram of the discharge unit is shown. It can be seen from the above figure that the discharge unit includes an inner arc shell 18 and an outer arc shell 19. The top edge of the inner arc shell 18 is fixedly connected to the edge of the discharge port 17 of the powder bin 15. Six first discharge holes 20 are distributed at equal angles on the peripheral edge of the inner arc shell 18, and six second discharge holes 21 are also distributed at equal angles on the peripheral edge of the outer arc shell 19. The inner arc shell 18 is concentrically mounted in the outer arc shell 19, and the six first discharge holes 20 are connected to the six second discharge holes 21. The two discharge holes 21 can be formed in a one-to-one relationship, and at this time, the pollen passes through the first discharge hole 20 and the second discharge hole 21 in turn to be discharged from the powder bin 15 (completing the discharge of the pollen); and when the first discharge hole 20 is misaligned with the corresponding second discharge hole 21, the peripheral edge of the outer arc shell 19 can block the first discharge hole 20 of the inner arc shell 18 (completing the stopping of the pollen); a rotating column 22 is fixed at the center of the outer arc shell 19, and the rotating column 22 passes through the bottom center of the inner arc shell 18 and forms a rotational connection with the inner arc shell 18. The pollen collecting mechanism also includes a cleaning unit, which specifically includes six arc plates 23, which are arranged in a circular array and together form a petal-shaped brush, the central part of which is fixedly connected to the rotating column 22 in the inner arc shell 18, and the outer arc surface of the single arc plate 23 is provided with bristles 24, and the bristles 24 of the arc plate 23 are in contact and adapted with the surface of the inner arc shell 18; at the same time, it is defined that the single arc plate 23 can be opposite to the adjacent second discharge hole 21, and when the second discharge hole 21 and the first discharge hole 20 gradually approach and form a relative relationship, the corresponding arc plate 23 thereby sweeps the pollen to move toward the first discharge hole 20 until the pollen enters the first discharge hole 20 and the second discharge hole 21. By setting the cleaning unit, it can be ensured that the pollen remaining in the inner arc shell 18 can also be discharged smoothly, thereby improving the discharge efficiency of the pollen. The rotating column 22 at the bottom of the outer arc shell 19 is connected to the second drive unit in a transmission manner, and the more specific structure of the drive unit is as follows.

[0040] The first implementation mode of the second drive unit is as follows: the second drive unit includes a motor (an existing product can be used), the motor is fixedly connected to the outer surface of the powder bin 15 through reinforcing ribs, and the output shaft of the motor is concentrically fixedly connected to the rotating column 22; the second drive unit of this implementation mode is not shown in the figure.

[0041] The second embodiment of the second driving unit is as follows: Fig. 9, which shows a schematic structural diagram of a second embodiment of the second drive unit. It can be seen from the figure that the second drive unit includes an electric pollinator powder sprayer 25 (for example, a DIY product can be used, which will not be described here). An upper hopper plate 26 is connected to the powder storage bin of the existing electric pollinator powder sprayer 25, and the upper hopper plate 26 is used to form a relative position with the second discharge hole 21 on the outer arc shell 19. A suspension arm 27 is fixedly connected to the outer surface of the driving power supply of the existing electric pollinator powder sprayer 25, and the other end of the suspension arm 27 is slidably connected to the top slide 28 of the powder loading bin 15; a driving source is fixedly connected to the powder loading bin 15, and the output end of the driving source is connected to the suspension arm 2 7 is fixedly connected, and the driving source is used to drive the boom 27 to slide in the top slide 28, so as to indirectly place the upper hopper plate 26 below the outer arc shell 19 or away from the outer arc shell 19; the second driving unit also includes a toothed disc 29, the toothed disc 29 is concentrically fixedly connected to the rotating column 22, and a toothed plate 30 is provided on one side of the toothed disc 29, and the toothed plate 30 is fixedly connected to the edge of the upper hopper plate 26, and the toothed disc 29 and the toothed plate 30 are meshed and linked to form a linkage; at the same time, it is defined that: when the upper hopper plate 26 is gradually placed directly below the outer arc shell 19, the toothed plate 30 meshes with the linkage toothed disc 29 and the outer arc shell 19 to rotate until the first discharge hole 20 and the second discharge hole 21 are relative to each other.

[0042] Specifically, one embodiment of the driving source is to directly use the existing electric telescopic rod, which is fixedly connected to the powder bin 15, and the output shaft of the electric telescopic rod is fixedly connected to the boom 27. The electric telescopic rod is not shown in the figure; another embodiment of the driving source is: Fig.10, which shows a schematic diagram of the installation structure of another embodiment of the driving source. It can be seen from the figure that the driving source includes an electromagnet 31, which is fixedly connected to the top slide 28, and a magnetic block 32 is fixedly connected to the arm 27 placed in the top slide 28, and the electromagnet 31 and the magnetic block 32 are arranged opposite to each other; at the same time, it is defined that: when the energized electromagnet 31 and the magnetic block 32 are in contact with each other, the upper hopper plate 26 is placed directly below the outer arc shell 19; an electric switch 33 is also fixedly connected to the electromagnet 31, and the electric switch 33 is used to control the start and stop of the electric pollinator powder sprayer 25. When the electromagnet 31 and the magnetic block 32 are in contact with each other, the arm 27 squeezes the electric switch 33 and starts the electric pollinator powder sprayer 25; a spring component is connected between the arm 27 and the top slide 28, and when the electromagnet 31 and the magnetic block 32 are not adsorbed, the spring component pulls the arm 27 back to its original position. When in use, first, choose a suitable pollination time, move the pollen collecting mechanism to the designated pollen collecting point, and then energize the electromagnet 31 through the controller. The energized electromagnet 31 attracts the magnetic block 32 and the suspension arm 27 to approach, thereby indirectly making the upper hopper plate 26 approach directly below the outer arc shell 19; then, until the electromagnet 31 contacts the magnetic block 32, the upper hopper plate 26 moves to the bottom of the outer arc shell 19, at which time the pollen enters the electric pollinator powder sprayer 25 through the upper hopper plate 26; and at the same time, the suspension arm 27 squeezes the electric switch 33 and turns on the electric pollinator powder sprayer 25, and the electric pollinator powder sprayer 25 starts the pollination operation.

[0043] Before pollen is used to pollinate another alfalfa flower, an extender needs to be mixed in the pollen in advance; for this purpose, the present invention further optimizes the pollen collection mechanism, referring to Fig.11 , which shows a schematic diagram of the assembly structure of the optimized pollen collecting mechanism. The pollen collecting mechanism also includes an extender feeding unit. Another function of the pollen collecting mechanism is to mix the extender into the pollen.

[0044] Combination Figure 11-12 ,in Fig.12What is shown is a schematic diagram of the partial structure of the optimized powder collecting mechanism, in which the increment agent feeding unit is connected to the powder loading bin 15. Specifically, the increment agent feeding unit includes an increment agent tank body 34, which is fixedly connected to the powder loading bin 15, and the increment agent tank body 34 is connected to the powder loading bin 15; a connecting pipe 35 is suspended in the powder loading bin 15, one end of the connecting pipe 35 is connected to the increment agent tank body 34 and forms a rotation connection, and the other closed end of the connecting pipe 35 rotates through the rotating column 22 and is placed outside the rotating column 22; a pin shaft 36 is rotatably connected to the outer arc shell 19 on one side of the rotating column 22, and a first rotating wheel 37 and a second rotating wheel 38 are concentrically fixedly connected to the pin shaft 36 in sequence, the first rotating wheel 37 is connected to the rotating column 22 through a belt to form a transmission connection, and the second rotating wheel 38 is connected to the connecting pipe 35 through a belt to form a transmission connection; a plurality of electric nozzles 39 are formed on the wall of the connecting pipe 35 placed in the inner arc shell 18. During use, when the outer arc shell 19 rotates, the electric nozzle 39 is started accordingly, and the extender flowing down from the extender tank 34 and the connecting pipe 35 is sprayed out from the electric nozzle 39; at this time, due to the linkage effect of the rotating column 22, the first rotating wheel 37, the second rotating wheel 38 and the belt are sequentially linked to operate, so that the connecting pipe 35 rotates, so that the pollen sprayed from the electric nozzle 39 is evenly sprayed on the pollen, so that the pollen and the mixed agent are initially mixed; secondly, combined with the cleaning movement of the cleaning unit, the pollen and the mixed agent are further mixed.

[0045] After the pollen enters the powder loading bin 15, in order to prevent the pollen from being mixed with impurities such as flowers and leaves and affecting the pollen quality, the present invention further optimizes the bulking agent feeding unit, thereby increasing the impurity removal function; specifically, refer to Fig.13, which shows a schematic diagram of the installation structure of the optimized extender feeding unit. It can be seen from the figure that the extender feeding unit also includes a dust shield 40, which is in the shape of a quadrangular pyramid, and the tip of the dust shield 40 points to the inner arc shell 18; the edges of the dust shield 40 are fixedly connected to the inner wall of the powder bin 15, and the dust shield 40 is provided with a plurality of filter holes 41, and the aperture of the filter holes 41 allows pollen particles to pass through; the dust shield 40 can effectively filter out impurities in the pollen without affecting the falling of the pollen; the middle part of the dust shield 40 can be movably sleeved on the outer wall of the connecting pipe. On the other hand, in order to avoid clogging of the filter hole 41, a hammer handle 42 is fixedly connected to the connecting pipe, and the end of the hammer handle 42 is connected to a knocking hammer 44 through an elastic component 43 (such as a spring, etc.); at the same time, it is defined that when the elastic component 43 is in a natural state, the knocking hammer 44 contacts and fits with the smooth surface of the dust shield 40. When in use, the connecting pipe drives the knocking hammer 44 to rotate during the rotation process. Since the edges of the dust shield plate 40 are protruding, the knocking hammer 44 will correspondingly drive the elastic component 43 to deform when passing through the edges of the dust shield plate 40. After passing through the edges, the knocking hammer 44 will return to its original position due to the action of the elastic component 43, and then it will knock on the dust shield plate 40 to avoid pollen blockage in the filter hole 41. At the same time, the vibration effect generated by the knocking can also indirectly make the extender and pollen more fully mixed.
