Technical Field
[0001] This invention relates to the field of crop breeding technology, specifically to a pollinator for maize breeding. Background Technology
[0002] Corn is one of the most important food, feed, and industrial raw material crops, becoming the number one food crop in 2007. Hybrid corn varieties have extremely high social adoption rates, and corn seeds are the most commercialized food crop, with corn breeding also having the highest degree of commercialization. Currently, corn breeding still relies on manual pollination and pollination methods, thus requiring the use of pollinators and pollinators for corn pollination and breeding. Most pollen collectors and pollinators on the market currently require manual operation, which means that when conducting pollen collection and pollination in large cornfields, workers need to constantly turn around to collect and pollinate the corn. During pollen collection and pollination, only single-plant pollination can be carried out. In addition, the corn on the stalks grows at different heights, requiring the hand-held spray gun to be moved up and down to collect and pollinate the corn, which further increases the manual burden and wastes time. Furthermore, due to manual operation, pollen cannot be collected sufficiently, affecting the total amount of pollen collected. During pollination, the probability of successful corn pollination can also be affected by the negligence of the workers. Summary of the Invention

[0029] The workflow of this invention is as follows: When using the corn pollinator, first connect the power supply to the device to put it into operation. Then, push the device between the corn stalks. At this time, the controller 8 controls the operation of the electric push rod 207. When the drive end of the electric push rod 207 moves, it drives the left connecting slide plate 204 and the connecting slider 205 to move on the connecting slide rail 206. When the left connecting slide plate 204 moves, it drives the right connecting slide plate through the connecting rotating rod 201, the connecting rotating plate 202, and the connecting rotating plate 203. The plate 204 moves outward, thereby adjusting the distance between the rotating air pipe 314 and the pollination nozzle 420 and the corn stalk. At this time, the camera 5 is controlled by the controller 8. When the camera 5 detects the corn flower, it transmits the signal to the controller 8. Then, the controller 8 controls the electric telescopic rod 209 to move. When the electric telescopic rod 209 moves, it drives the moving connecting plate 210 and the stabilizing slide bar 211 to move. When the moving connecting plate 210 moves, it drives the rotating air pipe 314 and the pollination nozzle 420 to move to the corresponding positions.
[0030] Subsequently, the controller 8 controls the operation of the hair dryer 7 and the drive motor 304. When the drive end of the drive motor 304 rotates, it drives the rotating rod 305 to rotate. The rotating rod 305 drives the rotating gear 306 to rotate. When the rotating gear 306 rotates, it drives the moving rack 307 to move forward. When the moving rack 307 moves forward, it drives the telescopic connecting plate 309 and the rotating blower pipe 314 to move forward. During the movement of the telescopic connecting plate 309, it drives the scissor-type telescopic frame 311 to unfold. When the telescopic frame 311 is unfolded, it drives the connecting slider 310 to move downward on the telescopic connecting plate 309 and drives the moving slider 312 to move downward on the connecting plate 313. When the connecting slider 310 moves downward on the telescopic connecting plate 309, it drives the rotating air pipe 314 to rotate from top to bottom around the connecting shaft between the telescopic connecting plate 309 and the rotating air pipe 314 through the fixed connecting seat 316 and the connecting pull plate 315. During this process, the pollen on the corn flowers can be blown into the funnel 303 more fully.
[0031] While pollen is being collected, the controller 8 controls the operation of the blower 6 and the rotary motor 402. When the drive end of the rotary motor 402 rotates, it drives the rotating shaft 403 to rotate. The rotating shaft 403 drives the rotating connecting plate 404 to rotate. When the rotating connecting plate 404 rotates, it drives the connecting slide plate 407 to move on the side wall of the fixed slide rod 408 through the connecting push plate 405 and the connecting connecting seat 406. When the connecting slide plate 407 moves, it drives the connecting bracket 409 to move. The connecting bracket 409 drives the connecting rotating rod 410, the limiting slide plate 411, and the connecting gear 41. 3. Moving on the limiting frame 412, under the action of the fixed rack 414, the connecting gear 413 drives the connecting rod 410 to rotate, and the connecting rod 410 drives the rotating plate 415 to rotate. When the rotating plate 415 rotates, the connecting shaft 416, the connecting bracket 417, and the connecting block 418 drive the swinging rod 419 to swing. When the swinging rod 419 swings, it drives the pollination nozzle 420 to swing during the upward process, which allows the corn flowers to come into full contact with the pollen sprayed from the pollination nozzle 420, thereby increasing the probability of successful corn pollination.
