Embodiment Construction

[0015] figure 1 The spiral cutter combination of the neutral spiral trencher is mainly composed of a main shaft, a helical blade, a helical soil cutting blade, a baffle plate, an end surface cutting blade, a drill tip, etc.; The blade drives the helical blade to carry out soil milling movement. The main shaft is designed as a hollow shaft, and the seamless steel pipe is used to reduce the weight of the tool. The most important part of the tool structure, its structural performance directly affects the power consumption of cutting soil and the performance of soil lifting and throwing. The helical blades are actually two variable pitch helical surfaces, which are composed of variable pitch The spiral blade is welded on the outer edge of the spiral blade, which reduces the wear of the spiral blade; the end face soil cutting blade is fixed on the knife seat welded to the end of the spiral blade through bolt connection , the thickness of both the blade and the tool seat is 3mm, an...

Abstract

A vertical helix ditching machine spiral cutter combination which is mainly composed of a main shaft, a spiral blade, a spiral soil cutting blade, a baffle, a transverse plane soil cutting blade and adrill tip; the main shaft is responsible for transmitting power output by a reduction box to the spiral blade and the main shaft is designed into a hollow shaft; the spiral blade is the most important part of the helical cutter structure and is composed of countless tangents of variable pitch spirals; the spiral cutting blade is welded on the outer edge of the spiral blade to reduce the wear of the spiral blade; the transverse plane cutting blade is fixed on the blade holder welded to the end of the spiral blade by bolting; the arc baffle is installed at a rear of the spiral cutter; the drilltip is installed at an end of the main shaft through welding; small taper screwed type drill tip is used. The invention has the advantages of simple structure, high working efficiency, low cost and convenient installation, and satisfies the requirements for the trenching of the vertical spiral trencher, and has important significance for improving the level of agricultural mechanization in China.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a helical cutter combination for a vertical helical ditching machine. Background technique [0002] The spiral cutter combination is the working part of the vertical spiral trencher. Its structural characteristics are related to the energy consumption of soil cutting. According to the shape of the groove section, there are two common types of spiral cutters: conical spiral cutter and cylindrical Spiral cutter. However, the existing opener cutter not only has low working efficiency, but also is easy to wear, which affects the ditching effect and easily damages the ditcher. Therefore, after continuous optimization, a new type of spiral cutter combination was designed to ensure the balance and stability of the machine. The device has a simple structure, high work efficiency, low cost, and easy installation, which meets the ditching requirements of the vertical spiral...
