Crusher capable of conveniently adjusting crushing size

Abstract

The invention discloses a crusher capable of conveniently adjusting the crushing size. The crusher comprises a discharge pipe, a crushing cylinder, a crusher shell, fixed hammers, rotary hammers, a feed hopper, movable hammers and a movable block, wherein the crushing cylinder is arranged in the crusher shell, the multiple fixed hammers are welded to the inner wall of the crushing cylinder, the multiple rotary hammers are connected to the side wall of a crushing roller through pin shafts, the lower part of the outer side of the movable block is connected to a movable hinge base, the movable hinge base is fixed to the end part of a connecting rod, and the connecting rod penetrates through a through groove in a baffle plate and is connected to a telescopic rod of an electric cylinder througha connector. The crusher has the advantages that the rotary hammers and the fixed hammers are used for crushing stone which falls between the rotary hammers and the fixed hammers, the crushing effectis good, the movable block is driven to rotate inwards or outwards around a fixed hinging base through the telescopic rod of the electric cylinder, so that gaps between the movable hammers and the rotary hammers can be adjusted, the particle size of the crushed stone can be further adjusted, and the crusher is convenient and fast to use.

Description

technical field [0001] The present invention relates to the technical field of crushing mechanical equipment, more specifically, it relates to a crusher which is convenient for adjusting the crushing size. Background technique [0002] Crushing is a process in which an external force is applied to the crushed material to overcome the cohesive force between the molecules of the material and split the large material into several small pieces. Crushing operations are divided into mechanical energy crushing and non-mechanical energy crushing such as electrical energy and thermal energy according to the energy consumed. In industry, mechanical force is mainly used for crushing, and the methods are as follows: crushing, chopping, breaking, grinding, impact crushing, etc. Mechanical crushing is more suitable for the crushing of brittle and hard materials, and has been widely used in the material treatment process of the mining and metallurgical industry. [0003] At present, in t...

AI Technical Summary

Problems solved by technology

[0003] At present, in the production of products in many industries such as mining, building materials, chemical industry, metallurgy, etc., the crushing of materials is an indispensable process. When crushing, the materials crushed by existing crushers are different in size and hardness. If the particle size of the crushed material needs to be changed, the crushing roller needs to be replaced in order to adjust the distance between the rotary hammer and the fixed hammer. This operation The method is time-consuming and labor-intensive, and it is not convenient for crushing production operations
