AI Technical Summary

Technical Problem

When traditional lawnmowers clean up grass clippings, the clippings tend to accumulate on the surface of the grass, affecting the appearance of the grass and the health of the plants. Existing cleaning methods are inefficient and ineffective.

Method used

Design a roller brush mechanism with a bent cleaning brush on the roller. The included angle of the bent structure is opposite to the direction of the roller's rotation. When the cleaning brush rotates, it can effectively press down grass clippings and knock them into the grass, thus improving the cleaning effect.

Benefits of technology

Through the design of the roller brush mechanism, most of the grass clippings are effectively cleaned into the grass, reducing the residue of grass clippings on the grass surface and improving the cleaning efficiency and aesthetics of the grass.

Abstract

The present application relates to a kind of brush mechanism and mower for weeding equipment, in the process of mowing, part of grass clippings is left on the surface of grass clump after cutting grass by cutting part, for this, drive roller rotates around its own axis, so that the brush rotates with the roller, so that the brush sweeps away the grass clump.Because at least one bending structure is provided on the brush, and in at least one bending structure, the included angle formed by the connecting part and the brushing part at the bending is opposite to the rotation direction of the roller, therefore, when sweeping away the grass clump, the brush has a brushing part that bends and extends in the opposite direction of the rotation direction, which can press the grass clippings on the surface of the grass clump to reduce the lift generated by the brush when leaving the grass surface, so that most of the grass clippings are beaten into the grass clump, thereby effectively improving the cleaning effect of grass clippings.
