Description

Technical Field

[0001] The utility model relates to the technical field of pollination for corn breeding, and more specifically, to a pollination device for corn breeding. Background Art

[0002] In the current corn breeding technology, the pollination device plays a vital role. Existing pollination devices usually use a storage shell to store pollen, and spray the pollen through compressed air to complete the pollination process. However, this device has certain limitations during use. First, after the pollen is placed in the storage shell, the pollination device sprays out a part of the pollen through compressed air. The key to this step is the adjustment of the air flow rate, because it directly affects the pollen injection speed and the uniformity of pollination. Unfortunately, the existing equipment is not convenient in adjusting the air flow rate, which leads to unstable pollination effect.

[0003] Since the air flow rate cannot be easily adjusted, the pollination device may spray pollen too quickly or too slowly during the pollination process. This uncontrollability not only affects the uniformity of pollination, but also may lead to pollen waste, thereby reducing pollination efficiency. In addition, inappropriate air flow rate may damage the quality of pollen, further affecting the quality and yield of seeds. Utility Model Content

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a pollination device for corn breeding, which has the following beneficial effects:

[0017] 1. The setting of the adjustment mechanism, especially the design of the push plate and the button, enables the operator to conveniently adjust the air flow rate according to the pollination needs. By pressing the push plate, the push spring is compressed, thereby unlocking the seal between the one-way disk and the receiving ring, allowing a larger flow of compressed air to pass through and achieve rapid pollination. On the contrary, by pressing the button, the spring is compressed, unlocking the seal between the bottom block and the bottom groove under the action of the rod, and adjusting to a small flow to supplement pollen. This design improves the flexibility and accuracy of pollination and ensures efficient operation under different pollination needs.

[0018] 2. The sealing mechanism effectively realizes the sealing function of the nozzle through the cooperation of the sealing ring and the threaded section, as well as the design of the friction groove and the fitting ring. When not in use, the sealing ring slides to the appropriate position through the rotation of the rotating disk, and the friction groove and the fitting ring fit tightly, thereby avoiding misoperation and waste of pollen. This sealing design not only ensures the safety and stability of the equipment, but also helps to extend the service life of the equipment and reduce maintenance costs.

[0030] In this embodiment, when pollinating corn, first, the pollen is loaded into the storage shell 20, and then the nozzle 1 is aimed at the corresponding position of the corn.
