Corrosion-resistant tree branch crushing cutter imitating the structure of beaver incisors

Abstract

The invention provides a beaver incisor structure-imitated anti-corrosion branch crushing tool. The anti-corrosion branch crushing tool consists of a bionic blade and positioning bolts, wherein the bionic blade consists of a bionic cutting edge and a tool holder; U-shaped positioning holes 5 are formed in the tool holder 4; each positioning bolt 2 is arranged in the corresponding U-shaped positioning hole 5 in manner of being perpendicular to the tool holder 4, thereby realizing fixed connection between the bionic blade 1 and a body of a crusher; the profile curve of the upper cutting surfaceof the bionic cutting edge 3 of the bionic blade 1 is a beaver incisor structure-imitated curve, and the curvilinear equation is as shown as follows: f(x)=a1x<2>+a0x; wherein the value range of a1 is-0.012 to -0.008, the value range of a0 is 0.55 to 0.70, and the value range of x is 0mm to 30mm; an MoS2 microballoon structure covers the upper surface of the bionic cutting edge; and nanopillars are distributed on the surface of the MoS2 in the radial direction. As a beaver incisor structure is imitated by the tool provided by the invention, during branch crushing, working resistance of the branch crushing tool is reduced, and crushing efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of bionic processing machinery, and in particular relates to a corrosion-resistant branch crushing cutter imitating the structure of beaver teeth. Background technique [0002] my country is rich in forest resources, and produces a large amount of forestry residues and garden wastes every year. At present, a variety of environmentally friendly and effective ways to deal with forest residues have been widely used, but the premise of processing forest residues is that the residues need to be crushed. The core component of the wood shredder is the crushing cutter, whose performance directly affects the working efficiency and crushing effect of the shredder. [0003] There are following defects in the existing wood chipper cutter: [0004] 1. During the process of crushing and cutting forest residues, the shredder cutter will produce forest wood pulp. After the blade contacts the pulp generated by the crushing...

AI Technical Summary

Problems solved by technology

[0004] 1. During the process of crushing and cutting forest residues, the shredder cutter will produce forest wood pulp. After the blade contacts the pulp generated by the crushing of forest trees, it is easily corroded, and the wear resistance and mechanical properties of the blade drop sharply, which leads to the work efficiency of the shredder. Low, requiring frequent replacement of crushing knives;

[0005] 2. The cutting resistance of the pulverizer tool is relatively large, which leads to problems such as high power consumption and low yield
