[0045] A method for collecting pollen for corn breeding, the method comprising:

[0046] S1: First, the cornflowers are gathered by the gathering component, the handheld collection head 5 is lowered, the cornflowers are sent into the collection head 5, and the cornflower stalks can be clamped by the driving of the motor 2 26;

[0047] S2: After clamping, the cornflower is inside the collecting head 5, and the motor 13 is started to vibrate the vibration plate 8, so as to achieve reciprocating vibration of the cornflower stalks, thereby shaking the cornflower into the collecting head 5;

[0048] S3: After shaking off, the corn pollen is sucked into the collecting box 1 through the fan 28, and the pollen is filtered through the filter assembly, and finally the pollen falls into the collecting bucket 29, thereby completing the pollen collection work.

[0049] Working principle: when in use, first wear the collection box 1 on the back through the shoulder strap 32, hold the hand-held hollow tube 4, and when collecting, align the top of the popcorn with the folding component to wrap the popcorn. At this time, the threaded rod 27 can be driven to rotate through the control of the motor 26. The rotation of the threaded rod 27 can realize the reciprocating movement of the slider 2 19 on the inner wall of the slide groove 16, thereby driving the rotating seat 20 connected to the lower surface of the slider 2 19 to move synchronously, realizing the movement of the rotating seat 20, and realizing the rotation of the rotating rod 1 21 and the rotating rod 2 22 through the movement of the rotating seat 20, thereby driving the folding and expansion of the right-angle rod 23. The inclined arc plate 24 can wrap the popcorn in the expanded state. When the arc plate 24 is folded, the collecting head 5 is lowered, and the popcorn can be folded into the collecting head 5 through the through holes on the vibrating plate 8 and the fixing ring 7, and the corn stalks can be clamped.

[0050] After the cornflowers enter the collecting head 5, the two motors 13 drive the two eccentric wheels 15 to rotate. The two eccentric wheels 15 rotate to make the vibration plate 8 slide back and forth on the fixed rod 9. The vibration plate 8 vibrates back and forth in coordination with the two springs 10 and the two springs 2 11. The arc-shaped plates 24 clamp the cornstalks and drive them to vibrate synchronously. The pollen on the cornflowers can be shaken off into the collecting head 5, replacing the traditional method of beating to extract the pollen, which causes the cornstalks to break and increases the impurity content.

[0051] When the pollen is shaken off, the operation of the fan 28 can create a negative pressure environment inside the collection box 1. The pollen can be transported to the inside of the collection box 1 through the handheld hollow tube 4, the connecting hose 3 and the air inlet pipe 2. Under the action of the negative pressure, the roller 33 rotates, driving the installation cavity 34 and the cleaning block 36 to rotate synchronously. Under the action of the compression spring 35 arranged inside the installation cavity 34, the cleaning block 36 can always fit with the surface of the filter screen 30 to improve the cleaning effect and prevent the filter screen 30 from being blocked when filtering out pollen sacs and husks, thereby affecting the collection of pollen. The filtered pollen falls into the collection bucket 29, which is convenient for taking out for subsequent fertilization operations.

[0052] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
