Multifunctional rotary cultivator cutter shaft assembly

Abstract

The invention relates to a multifunctional rotary cultivator cutter shaft assembly, and belongs to the technical field of agriculture rotary cultivator fittings. The multifunctional rotary cultivator cutter shaft assembly comprises a cutter shaft tube, plough cutter bases and rotary cutters; a plurality of support rings are mounted at intervals on the cutter shaft tube; the plurality of plough cutter bases are uniformly distributed at intervals on the circumference surface of the cutter shaft tube and between the support rings; the rotary cutters are movably mounted inside the plough cutter bases; a plurality depth limiting rods are uniformly distributed on the circumferences of the support rings; protection covers are respectively arranged on the cutter shaft tube at two end tips of each depth limiting rod. The rotary cutters of the cutter shaft assembly are mounted in a spiral manner, the blade penetration resistance is small, and ploughed soil is not hardened. Due to adoption of the protection covers, an assembling bearing can be effectively prevented from being wound by weeds, and thus the rotary plough effect can be greatly improved. The multifunctional rotary cultivator cutter shaft assembly is applicable to rotary plough operation of dry farmlands and rotary plough operation of paddy fields, and thus the investment cost of agriculture machines can be lowered.

Description

technical field [0001] The invention relates to a multifunctional rotary tiller cutter shaft assembly, which belongs to the technical field of agricultural rotary tiller accessories. Background technique [0002] The rotary tiller is a kind of tillage machine developed recently in our country, and the cutter shaft assembly of the rotary tiller 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 ca...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a simple structure and good practicability, which can effectively solve the problem that the existing rotary tiller is installed symmetrically in a cross shape, the resistance of the blade to the soil is large, the depth of the rotary tillage is different, and the weeds are easily entangled to the rotary tiller during work. On the tiller, it not only affects the effect and quality of rotary tillage, but also is easy to cause damage to the machine. The multifunctional rotary tiller shaft assembly
