Technical Field

The invention relates to the technical field of agricultural coulters, in particular to an anti-blocking agricultural coulter during cutting.

Background

The disc plough is mounted on the tractor and is powered by the tractor, and the plough blade rotates during operation to plough soil, so that the disc plough is particularly suitable for the ploughing operation of complex farmlands with weeds clustered, upright stems, large specific soil resistance, broken bricks and stones in the soil and the like. The traditional disc plough only has one group of coulters, the disc plough adopts unilateral transmission, the transmission resistance of a transmission shaft is large, all the coulters turn soil in one direction, thus a tractor is greatly stressed by force in one direction, and the service life of a transmission device of the tractor and the service life of the whole tractor are greatly influenced.

The searched Chinese patent number is CN201510650965.X discloses a coulter assembly for a disc plough for ploughing soil. The coulter assembly for the disc plough has small transmission resistance and enables a tractor to be stressed evenly in the plowing process. The coulter assembly for the disc plough comprises two disc coulter shaft assemblies and a middle coulter, wherein the two disc coulter shaft assemblies are respectively arranged on two sides of a riding frame of the disc plough, but the coulter assembly is particularly labored when meeting a section with serious disc root dislocation in the ground during ploughing, and even causes a roller winding phenomenon.
