Description

Technical Field

[0001] The utility model relates to a seeder, in particular to an integrated brush and a seeding mechanism thereof. Background Art

[0002] The function of the seeding mechanism on the seeder is that when the seeding wheel rotates, the seeds are discharged from the gaps of the seeding wheel. In order to prevent the seeds from adhering to the gaps and returning to the entrance, a brush is often provided on the housing of the seeding mechanism to clean the seeds in the gaps, and the seeds fall to the outlet of the mechanism after contacting the brush.

[0003] When the existing brushes are installed on the seeding mechanism, multiple brushes are independently connected to the seeding mechanism. Over time, the relative rotation between the brushes and the seeding wheel will cause the brushes to wear and need to be replaced. When the brushes need to be replaced, the machine needs to be shut down and the shell needs to be disassembled and replaced, which is time-consuming and labor-intensive.

[0004] In summary, how to replace the brush on the seeding mechanism has become an urgent problem that researchers in this field need to solve. Utility Model Content
