specific Embodiment approach

[0025] In order to further illustrate the technical solutions of the present invention, in conjunction with the accompanying drawings, the specific embodiments of the present invention are as follows:

[0026] like figure 1 and image 3 As shown in the figure, the present invention provides a bionic branch smashing tool based on a beaver incisor structure. 3 and the shank 4 at the rear end of the integrated structure, the rear end of the shank 4 is symmetrically opened with two U-shaped positioning holes 5 with horizontal openings facing backward, and the positioning bolts 2 have two groups, which are respectively perpendicular to the The handle 4 is installed in the U-shaped positioning hole 5, so as to realize the fixed assembly connection between the bionic blade 1 and the body (not shown in the figure) of the shredder.

[0027] like figure 2 As shown, the contour curve CD of the upper cutting surface of the bionic cutting edge 3 of the bionic blade 1 is to imitate the ...

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 tool imitating a beaver tooth structure. Background technique [0002] my country is rich in forest resources and produces a large amount of forestry residues and garden waste every year. At present, a variety of environmentally friendly and effective ways to deal with forest tree residues have been widely used, but the premise of dealing with forest tree residues is that the residues need to be pulverized. The core component of the branch pulverizer is the pulverizing tool, and its performance directly affects the working efficiency and pulverizing effect of the pulverizer. [0003] The existing wood chipper cutters have the following defects: [0004] 1. During the process of smashing and cutting the residue of forest trees, the pulverizer tool will produce forest wood slurry. After the blade contacts with ...
