Description

Technical Field

[0001] This utility model relates to the field of maize breeding technology, and in particular to a pollinator for maize breeding. Background Technology

[0002] Corn is an important food crop belonging to the Poaceae family. It is one of the most widely cultivated crops in the world. It is not only one of the main sources of human food, but also an important source of livestock feed, industrial raw materials, and bioenergy. Compared with traditional food crops such as rice and wheat, corn has strong drought resistance, cold resistance, tolerance to poor soil, and excellent environmental adaptability.

[0003] With the development of production, corn has become increasingly important as a feed crop in my country. In the process of hybridization and breeding, artificial pollination is required. In order to improve the pollination rate, the corn tassels are usually moved manually to make the pollen fall onto the female ears to complete the pollination, or pollinators are used for pollination.

[0004] Existing pollinators for corn breeding involve manually pushing the pollinator through the field, using an air pump to extract pollen from the feed hopper, and then spraying the pollen out through a nozzle for pollination. During use, the pollen tends to accumulate and clump in the feed hopper, affecting the spraying of pollen and reducing pollination efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problem that pollen tends to accumulate and clump in the feed box during use, which affects pollen spraying and reduces pollination efficiency. Therefore, this invention proposes a pollinator for corn breeding.

A second bevel gear is fixedly connected to both the drive shaft and the lead screw. The two second bevel gears are meshed together, and a belt is connected between the drive shaft and the rotating shaft.
