Abstract

The invention discloses a tool group of a tillage machine. The tool group comprises a rack tool shaft, tool bases, left curved blades and right curved blades, wherein the tool bases are fixedly connected with the tool shaft; the left curved blades and the right curved blades are fixedly connected in the tool bases; the tool bases for fixing the left curved blades and the tool bases for fixing the right curved blades are respectively distributed along spiral lines with the same spiral direction of outer walls of the tool shaft; the improvements are as follows: the two spiral lines for distributing the tool bases for fixing the left curved blades and the tool bases for fixing the right curved blades are the same in helical pitch, and the helix angles are 5-15 degrees; the tool bases for fixing the left curved blades and the tool bases for fixing the right curved blades are respectively arranged at equal intervals along the spiral lines; the left curved blades and the right curved blades are sequentially arranged in a staggered manner. The tool group has the advantages that the use effect of the tool group of the tillage machine is greatly improved, the tillage flatness degree is good, the working stability is enhanced, and loads of the tool shaft are uniform.

Description

technical field [0001] The invention relates to a tiller cutter set. Background technique [0002] With the development of agriculture, cultivators are widely used in agricultural production. The knife seats of the existing cultivator cutter sets are all welded on the cutter shaft in a linear manner. The intermittent impact force of this tiller cutter set is very large during operation, resulting in increased vibration of the unit and incomplete stubble removal. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention proposes a cultivator cutter set capable of improving working stability and ensuring uniform load on the cutter shaft. [0004] The present invention achieves technical goals through the following technical solutions. [0005] Tillage machine tool set, including frame cutter shaft, knife seat, left curved blade, right curved blade; the knife seat is fixedly connected to the knife shaft, and the left curved blade and righ...
