Abstract

The invention relates to an internal reaming type anti-drag coulter of a rotary cultivator. The internal reaming type anti-drag coulter comprises a coulter shaft and a coulter blade on the coulter shaft, wherein the coulter blade comprises positive coulter blades and negative coulter blades, and the positive coulter blades and the negative coulter blades are symmetrically mounted on the coulter shaft; positive bent parts and negative bent parts are respectively arranged at the outer ends of the positive coulter blades and the outer ends of the negative coulter blades and bent towards the outer end of the coulter shaft; an internal reamer, which is of a disk-shaped structure, is mounted on the coulter shaft between the positive coulter blades and the negative coulter blades; the internal reamer is provided with cutting teeth which are symmetrically distributed around the center of the internal reamer and are alternately arranged; first anti-drag holes are formed in the positive coulter blades; first cutting teeth are formed in the concave surface sides of the positive bent parts of the positive coulter blades; second anti-drag holes are formed in the negative coulter blades; second cutting teeth are formed in the concave surface sides of the negative bent parts of the negative coulter blades; third anti-drag holes are formed in the cutting teeth. The internal reaming type anti-drag coulter has the characteristics of being high in rotary cultivation efficiency and good in effect.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a walk-behind rotary tiller. Background technique [0002] A rotary tiller is a tillage machine that is matched with a tractor to complete plowing and harrowing operations. It has been widely used because of its strong ability to crush soil and flat surface after plowing. [0003] The internal hinged drag-reducing coulter of the rotary tiller in the prior art has an unreasonable structural design of the coulter, and the rotary tillage efficiency is not high and the effect is not good. Contents of the invention [0004] Aiming at the above-mentioned disadvantages of the existing production technology, the applicant provides an internally hinged drag-reducing coulter of a rotary tiller with reasonable structure and high working efficiency. [0005] The technical scheme adopted in the present invention is as follows: [0006] An internally hinged drag-reducing co...
