Description

Flat-head soil loosening cutter

Technical Field

The utility model relates to a sword technical field that loosens the soil especially relates to a crew cut sword that loosens soil.

Background

A scarifier is a machine for raking hard soil, frozen soil, old road surfaces and even medium-hardness rocks by using a tooth-shaped scarifier in earthwork construction. According to the connection form of the scarifier and the tractor, the scarifier has two types of drag type and suspension type. The harrow teeth are cut into the soil by using the traction force provided by the tractor and the weight of the scarifier, the hard soil is turned, and a soil loosening zone is left after the machine passes through the scarifier. It is often used for pre-scarification operations before bulldozer or scraper operations. Most of the existing scarifiers drive the scarifier blades to rotate through a driving mechanism to loosen the soil, and the scarifier blades only play a role in loosening the soil when working and cannot cut off and eradicate weeds in the field.
