Before the slide 241 contacts the powder rod 340, the push plate 260 pushes the push arm 640, so that the push block 630 presses the air bag 620 to blow air, and the blown air sequentially passes through the guide passage 421 and the air supply passage (the third axial cavity 380) to enter the air blowing passage 342 as shown in fig. 14. The air flow entering the air blowing passage 342 pushes the control block 346 to extend into the accommodating groove 341 until the air guide hole 347 communicates with the accommodating groove 341. At this time, the control block 346 can not only help to break up pollen in the accommodation groove 341, but also introduce air flow into the accommodation groove 341 by using the air guide hole 347 so that pollen is ejected from the pollen outlet 360, the guide duct 361 and the pollen nozzle 700 in order to complete pollination operation of the flowers of green pepper.

The control shaft 200 continues to rotate, the first sliding sleeve 240 continues to move along the first guide rod 300 toward the first stop block 320, and after the sliding block 241 contacts the powder rod 340, the sliding block 241 can push the powder rod 340 out of the first axial cavity 330, and at the same time, the air bag 620 is completely compressed. During the process of pushing the powder rod 340 by the slider 241 to extend, the air bag 620 is not compressed any more, and the fourth elastic member 252 is stretched, so as to provide a buffer space for the push plate 260. At this time, the powder rod 340 protrudes into a side of the pollen box 500 away from the second stopper 410 to take out the powder, as shown in fig. 15. Until the first sliding sleeve 240 engages the first stop 320.

The control shaft 200 continues to rotate, the first sliding sleeve 240 keeps being jointed with the first stop block 320, the second sliding sleeve 310 moves towards the second stop block 410 along the second guide rod 400, in this state, the powder rod 340 moves from one side to the other side of the pollen box 500 along the axial direction of the second guide rod 400, in this embodiment, the opening direction of the accommodating groove 341 is the same as the direction that the third stop block 420 points to the second stop block 410, so that the accommodating groove 341 is convenient to be filled with pollen and can compact the pollen.

In this embodiment, the diameter of the pollen rod 340 is smaller than the inner diameter of the pollen box 500 in the axial direction of the control shaft 200, and when the second sliding sleeve 310 moves to be engaged with the second stopper 410, the pollen rod 340 is engaged with a side wall of the pollen box 500 adjacent to the second stopper 410.

The control shaft 200 continues to rotate and the straw 340 may be retracted into the first guide 300 for the next pollination operation.

That is, the control shaft 200 can complete one pollination operation by rotating in one direction, so that the pollination operation is simple and efficient, and the pollen rod 340 can accurately take pollen in the pollen box 500, so that the uniformity of the pollen amount in each pollination operation is ensured.

In conclusion, the pollinating device for green pepper breeding provided by the embodiment of the invention can more accurately control the pollen consumption of single pollination, is simpler to operate and more efficient in pollination, can continuously carry out pollination operation, effectively improves the pollen utilization rate, and optimizes the pollination effect.

The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
