Fig.13 As shown, the second sleeve 310 is fitted with the third stop block 420, and the guide channel 421 is smoothly connected with the air supply channel, so that the air blowing assembly 600 is connected with the air blowing channel 342. At the same time, the guide tube 361 is also aligned with the pollen nozzle 700, so that the powder outlet 360 is in a communication relationship with the pollen nozzle 700, and the push plate 260 also moves smoothly to the side of the push arm 640 away from the third stop block 420.

[0090] The control shaft 200 continues to rotate, the second sleeve 310 and the third stop block 420 remain in contact, the first sleeve 240 moves along the first guide rod 300 toward the first stop block 320, and the slider 241 moves along the axial slide groove 350 toward the powder rod 340. Before the slider 241 contacts the powder rod 340, the push plate 260 pushes the push arm 640, so that the push block 630 squeezes the airbag 620 to blow air. Fig.14 As shown, the blown gas passes through the guide channel 421 and the air delivery channel (third axial cavity 380) in sequence and enters the blowing channel 342. The airflow entering the blowing channel 342 pushes the control block 346 to extend into the receiving groove 341 until the air guide hole 347 is connected to the receiving groove 341. At this time, the control block 346 can not only help to break up the pollen in the receiving groove 341, but also use the air guide hole 347 to introduce the airflow into the receiving groove 341, so that the pollen is ejected from the pollen outlet 360, the conduit 361 and the pollen nozzle 700 in sequence to complete the pollination operation of the green pepper flower.

[0091] The control shaft 200 continues to rotate, and the first sliding sleeve 240 continues to move along the first guide rod 300 toward the first stop block 320. When the slider 241 contacts the powder rod 340, the slider 241 can push the powder rod 340 out of the first axial cavity 330. At the same time, the airbag 620 is also completely squeezed and compressed. In the process of the slider 241 pushing the powder rod 340 out, the airbag 620 will no longer be compressed, and the fourth elastic member 252 is stretched to provide a buffer space for the push plate 260. At this time, the powder rod 340 extends into the side of the pollen box 500 away from the second stop block 410 to take the powder, as shown in FIG. Fig.15 Until the first sliding sleeve 240 is in contact with the first stop block 320 .

[0092] The control shaft 200 continues to rotate, the first sleeve 240 remains in contact with the first stop block 320, and the second sleeve 310 moves along the second guide rod 400 toward the second stop block 410. In this state, the powder rod 340 moves along the axial direction of the second guide rod 400 from one side of the pollen box 500 to the other side. In this embodiment, the opening direction of the receiving groove 341 is the same as "the direction in which the third stop block 420 points to the second stop block 410". In this way, it is convenient to fill the receiving groove 341 with pollen and compact the pollen.

[0093] In this embodiment, the diameter of the powder rod 340 is smaller than the inner diameter of the pollen box 500 in the axial direction of the control shaft 200. When the second sleeve 310 moves to fit with the second stop block 410, the powder rod 340 fits with the side wall of the pollen box 500 close to the second stop block 410.

[0094] The control shaft 200 continues to rotate, and the pollination rod 340 can be retracted into the first guide rod 300 to perform the next pollination operation.

[0095] That is to say, the control shaft 200 can complete a pollination operation by rotating one circle in one direction, which is simple and efficient, and the pollen rod 340 can accurately collect pollen in the pollen box 500 to ensure the uniformity of pollen amount in each pollination operation.

[0096] In summary, the pollination device for green pepper breeding provided by the embodiment of the present invention can more accurately control the amount of pollen used in a single pollination, is simpler to operate, and is more efficient in pollination. Pollination operations can be performed continuously, which effectively improves the pollen utilization rate and optimizes the pollination effect.

[0097] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
