[0035] Please refer to figure 1 and figure 2 , this embodiment provides a bionic design method for the structure of the pulverizer hammer and the structure of the pulverizer hammer manufactured according to the method. The structure of the pulverizer hammer is similar to the structure of the beaver incisors, and the beaver incisors can be divided into upper left, lower left and upper right , the lower right four incisors, this implementation content takes the upper right incisor as an example to illustrate, the structure of the pulverizer hammer includes a main part and sawtooth structures 3 arranged on both sides of the main part, the main part is in the shape of a rectangular sheet, and the sawtooth is the basis In the hammer sawtooth structure 3 obtained by the bionic design method, a plurality of sawtooths are arranged at intervals and arranged in a row, and there is a row on both sides of the main body, and the main body is provided with two spaced first connection holes...

Abstract

The invention discloses a bionic design method for a hammer sheet structure of a crusher, which comprises the following steps: selecting a mature and complete beaver incisor as a bionic prototype, obtaining point cloud data of the beaver incisor through industrial CT (computed tomography), constructing a three-dimensional solid model of the beaver incisor by using reverse engineering software, analyzing the scanned beaver incisor structure, carrying out finite element simulation on the tooth cutting movement process through finite element software, determining functional features on the incisor, extracting incisor feature parameters, designing corresponding response surface test schemes, simulating and analyzing all the designed test schemes through a finite element method, and then designing the optimal bionic hammer, wherein according to the designed crusher hammer sheet structure, sawtooth structures which are arranged at intervals are arranged on the two sides of an original structure; According to the method, the material crushing efficiency of the hammer sheet can be improved, and the service cycle of the hammer sheet is prolonged.

Description

technical field [0001] The invention relates to the technical field of powder processing, in particular to a bionic design method for a pulverizer hammer blade structure. Background technique [0002] As a large agricultural country, my country produces a large amount of straw every year. According to the data from the Ministry of Agriculture and Rural Affairs, my country produces about 900 million tons of straw every year, but the comprehensive utilization rate of these straws is less than 40%. Straw treatment is an important topic at this stage. Feed and fertilizer are one of the important ways of straw treatment. Straw needs to be pulverized before it is used as feed and fertilizer. [0003] Straw shredder is an important tool for crushing straw, which can effectively process straw. Hammer is the core component of the straw grinder, and its crushing performance directly affects the product quality. Most of the existing hammers on the market are rectangular hammers, whic...
