AI Technical Summary

Technical Problem

There are large gaps between the crushing knives of the existing crushing device, which leads to poor rotary tillage effect, large resistance, weeds entangled in the knife barrel, and affects balance and work efficiency.

Method used

A crushing and anti-wrapping knife group is arranged between the crushing knife groups, including the first and second crushing mechanisms. The first crushing mechanism is bent to one side, and the second crushing mechanism is located on the outer folding surface. The crushing and anti-wrapping knife groups are staggered along the axial and radial directions of the knife barrel to increase the crushing area, improve the soil breaking and grass breaking efficiency, and avoid weed entanglement.

Benefits of technology

The gap between the crushing blades is shortened, the rotary tillage efficiency is improved, the resistance is reduced, the crawling ability of the crushing device is enhanced, the weed entanglement is avoided, and the rotary tillage effect and balance are improved.

Abstract

The utility model relates to an anti-winding crushing device which comprises a cutter cylinder, one end of the cutter cylinder is connected with a crushing cutter set I, the other end of the cutter cylinder is connected with a crushing cutter set II, a plurality of crushing anti-winding cutter sets are arranged between the crushing cutter set I and the crushing cutter set II, and the crushing anti-winding cutter sets are connected with the cutter cylinder; the crushing anti-winding cutter group comprises a plurality of crushing anti-winding cutters, each crushing anti-winding cutter comprises a first crushing mechanism and a second crushing mechanism, the first crushing mechanism is bent towards one side and comprises a first outer folding surface and a first inner folding surface, and the first outer folding surface and the first inner folding surface are oppositely arranged; the second crushing mechanism is located on the first outer folding face. Gaps between the crushing cutters can be shortened through the crushing anti-winding cutter set, the soil breaking efficiency, the grass crushing efficiency and the crawling capacity of the gaps can be improved, soil and weeds at the gaps can be crushed in time by arranging the second crushing mechanism on the outer folding face, and the weeds at the gaps are prevented from being wound on the cutter cylinder.
