Description

Technical Field

[0001] The utility model relates to the field of corn breeding, in particular to a portable pollinator for corn breeding. Background Art

[0002] Corn is an annual monoecious, cross-pollinated plant with tall plants and strong stems. It is an important food crop and feed crop, and also the crop with the highest total output in the world. The pollen of corn is on the top of the ear, and falls onto the corn ear after maturity, and is pollinated by corn silk. Artificial assisted pollination is the artificial collection of pollen for unpollinated filaments. It is a yield-increasing measure to increase the number of grains per ear. At this time, a pollinator will be used to assist corn breeding pollination.

[0003] In the utility model with Chinese patent authorization announcement number "CN214178494U", a portable pollinator for corn breeding is disclosed. The device facilitates the disassembly and assembly of the air guide hose and the rubber airbag through the threaded first conduit and the second joint. At the same time, the threaded second conduit and the first joint facilitate the disassembly and assembly of the conical pollen collecting cover, which is convenient for disassembly and assembly of the pollinator. By sleeve-fitting the conical pollen collecting cover with the corn cob setting, rotating the two rotating rods so that two magnetic arc-shaped sleeve blocks with opposite magnetic properties are sleeved with the corn cob stalk setting, the sprayed pollen is effectively concentrated to avoid the pollen from scattering, thereby ensuring the pollination effect.

[0004] However, during the implementation of the technical solution of the above patent, it is impossible to change the direction of the powder outlet while ensuring that the powder storage barrel is vertical. The angle of the powder outlet of the existing corn breeding pollinator relative to the powder storage barrel cannot be adjusted. When operating, the operator will change the angle of the handheld device to align the powder outlet with the corn silk. Since the pollen in the pollen storage barrel falls into the powder outlet pipe due to its own gravity, the powder storage barrel will also tilt accordingly when the powder outlet is tilted, or even fall over, resulting in less powder output or failure to output powder normally, thereby affecting the normal breeding of corn.

[0005] Therefore, it is necessary to provide a new portable corn breeding pollinator to solve the above-mentioned technical problems. Utility Model Content
