Crusher for cast iron wallboard

Abstract

The invention provides a crusher for cast iron wallboards, which is characterized in that: the wallboards are integral one-time casting forming boards, and the wallboards are divided into left and right wallboards, which are respectively connected to the upper hopper, the platform and the side boards. The left and right wallboards are respectively movably connected with stopper blocks, and the left and right wallboards have built-in crushing rollers, and crushing knives are equidistantly installed on the crushing rollers; the thickness of the stopper blocks is smaller than the distance between any two crushing knives; The built-in crushing rollers of the left and right wallboards are crushing roller A and crushing roller B. The crushing rollers A and B are arranged in parallel, and the crushing knives on the crushing rollers are respectively embedded in each other. Respectively set on the crushing roller A and the crushing roller B in the rectangular space area where the crushing knives are embedded in each other; the wallboard surface is evenly provided with multiple rows of square frame reinforcement ribs to improve the bearing strength of the wallboard to the crusher, and the wallboard is The bolt holes connected with the material retaining block, upper hopper, platform and side plate are directly casted for easy connection and replacement.

Description

technical field [0001] The invention relates to the field of crushing machinery, in particular to a crusher for cast iron wallboards. Background technique [0002] The function of the crusher composed of single-shaft crushing roller or multi-shaft crushing roller is mainly used for crushing materials, and crushing materials into different sizes according to different requirements. [0003] At present, the crusher is mainly composed of crushing rollers, wall panels, side panels, upper hoppers, lower hoppers, platforms and power systems. The wall panels, side panels, hoppers, and platforms are connected by bolts, and the crushing roller is an assembly part in which the crushing knives are connected to the shaft and the distance between them is fixed by a spacer. [0004] The multi-axis crushing rollers are misplaced to achieve the effect of shearing and crushing. The shearing area is limited to the embedded segment between the crushing knives, and the distance between the non...

Problems solved by technology

[0006] The problem to be solved by the present invention is the complicated welding of the wallboard of the existing crusher and the difficulty in installing and replacing the retaining block. It provides a crusher for the cast iron wallboard, which adopts the integral one-time casting process of the wallboard and is equipped with unique reinforcing ribs. And directly cast the bolt holes connected with the material block, upper hopper, platform and side plate to connect the bolts of the material block with corresponding threaded holes, and at the same time improve the load-bearing strength of the wall plate to the crusher
