Rotary cultivator cutter shaft assembly

Abstract

The invention relates to a rotary tiller blade shaft assembly, and belongs to the technical field of agricultural machine components. The rotary tiller blade shaft assembly comprises a blade shaft, rotary blade bases, rotary blades and grass-preventing rings, wherein assembly discs are fixedly installed on the blade shaft at intervals, the rotary blade bases are welded between the circumferences of the assembly discs, rotary blades are welded to the rotary blade bases, and the grass-preventing rings are arranged at the two ends of the blade shaft respectively; corner blades and grass cutting blades are evenly distributed on the circumferences of the assembly discs close to the grass-preventing rings, the rotary blade bases of the rotary tiller blade shaft assembly are installed on the blade shaft in a staggered mode, and the rotary blades are oppositely installed on the adjacent rotary blade bases. Soil penetration resistance of the blades is small, soil does not harden after rotary tillage, and the rotary tillage effect is greatly improved. The rotary tiller blade shaft assembly is adaptable to rotary tillage operation on upland fields and paddy fields, and reduces cost of investment in agricultural machines by farmers. The rotary blades are pentagonal, abrasion can be effectively reduced, and the service life can be prolonged.

Description

technical field [0001] The invention relates to a cutter shaft assembly of a rotary tiller, which belongs to the technical field of agricultural machinery components. Background technique [0002] The rotary tiller is a kind of tillage machine developed in our country in recent years, and the rotary tiller shaft assembly is one of the most important parts of the rotary tiller. The knife shaft assembly of the rotary tiller is installed on the frame of the rotary tiller through the short shaft and the bearing seat, and the rotary tiller is installed on the knife shaft through the knife seat, and the knife seat is installed symmetrically in a cross shape on the knife shaft; it integrates Plowing and harrowing are integrated, and one rotary plowing operation on the farmland can achieve the working effect of plowing and harrowing several times with oxen. Due to the limitation of the structural form of the cutter shaft assembly, the current rotary tiller cannot be used in both dr...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a rotary tiller that is installed in a misplaced position on the knife shaft, and has a weed protection and grass pressing device; to solve the problem that the existing rotary tiller is installed in a cross-shaped symmetry, and the resistance of the blade to the soil is large Rotary tillage has different depths, and weeds are easy to wrap around the rotary tiller when working, which not only affects the effect and quality of rotary tillage, but also easily causes damage to the machine.
