Cutter shaft assembly of paddy and upland dual-purpose rotary cultivator

Abstract

The invention relates to a cutter shaft assembly, particularly relates to a cutter shaft assembly of a paddy and upland dual-purpose rotary cultivator, and belongs to the technical field of componentsof agricultural machinery. The cutter shaft assembly comprises a cutter shaft, cultivation cutter heads, rotary cultivation cutters, a plurality of support discs and a grass pricking depth limit rod.A spline housing is arranged at an end of the cutter shaft, the support discs are welded on the cutter shaft at intervals and are positioned between the spline housing and a bearing block, the cultivation cutter heads are uniformly distributed on the circumference of the cutter shaft and are positioned between the support discs, and the rotary cultivation cutters are fixedly arranged on the cultivation cutter heads via bolts. The cutter shaft assembly of the rotary cultivator has the advantages that the cultivation cutter heads are mounted on the cutter shaft in a dislocation manner, the rotary cultivation cutters are oppositely mounted on the adjacent cultivation cutter heads, accordingly, blades are low in soil entering resistance, soil is free of hardening after rotary cultivation is carried out, and rotary cultivation effects can be greatly improved.

Description

technical field [0001] The invention relates to a cutter shaft assembly, in particular to a cutter shaft assembly for a dual-purpose rotary tiller for flood and drought, and 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. The rotary tiller is a driven soil tillage machine with a rotary knife shaft assembly for the purpose of rotary tillage. According to the configuration of the rotary blade shaft, it can be divided into two types: horizontal axis type and vertical axis type. According to the nature of the farmland, it can be divided into dry field rotary tiller, paddy field rotary tiller and compound rotary tiller for both paddy and dry fields. As one of the most important components of the rotary tiller, the rotary tiller shaft assembly is installed on the frame of the rotary tiller through the short shaft and the bearing seat, and the ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a method that can effectively increase the width of the tillering pair, the resistance of the rotary tiller to the soil is small, the depth of the rotary tillage is consistent, and the performance of stably breaking the soil and embedding grass is good during operation, so as to solve the problem that the existing rotary tiller adopts an array type. Difficulty entering the soil caused by the distribution, large transmission power consumption, stable soil breaking performance and grass burying performance during operation are affected by the cutter shaft assembly of the rotary tiller
