Combined conveniently-detached tool for multi-jaw waste material breaker

Abstract

The invention discloses a combined conveniently-detached tool for a multi-jaw waste material breaker. The combined conveniently-detached tool for the multi-jaw waste material breaker comprises a rotary tool rest, cutters, bent cutters and colliding cutters; the rotary tool rest is formed by machining a tool rest and a spacer bush integrally; each bent cutter and the corresponding cutter are movably connected to form an assembly; the colliding cutter and the corresponding cutter are movably connected to form another assembly; and 2-4 cutter assemblies with the bent cutters and 2-4 cutter assemblies with the colliding cutters are respectively movably connected with the rotary tool rests through the cutters, and are uniformly distributed along the peripheral direction of the rotary tool rest. The tool provided by the invention is simple to mount and detach, convenient to replace, and short in maintenance time, and improves the using efficiency of a breaker; a tool with expressive price can be repaired and then is recycled, and the using cost is lowered; and the combined conveniently-detached tool can operate through the connection of a key slot in the rotary tool rest and a main shaft of the breaker by a flat key, a long hexagon or long spline shape which is required to be machined for the main shaft of the common breaker is avoided, and the manufacturing cost of the breaker is lowered.

Description

technical field [0001] The invention relates to a cutter used on a crusher, in particular to a combined detachable cutter for a multi-claw scrap crusher for crushing metal waste. Background technique [0002] The cutter used in the crusher for crushing metal waste is a kind of vulnerable part, which is damaged due to wear, chipping and impact, which is also a key factor affecting the use of the crusher. The cutter is generally made of alloy tool steel with special Manufactured by heat treatment process, the price is expensive, which also results in high manufacturing and use costs of the crusher. At present, the cutting tool of domestic and foreign waste crushers is to make the rotary knife seat into two separate components of the knife seat and the spacer sleeve, and then fix the cutting knife, hook knife and collision knife on the knife seat by welding. The tool with this structure has the following disadvantages: (1) The tool is fixed by welding, and the high temperature...

AI Technical Summary

Problems solved by technology

The tool with this structure has the following disadvantages: (1) The tool is fixed by welding, and the high temperature generated during welding will cause local tempering, reduce the surface hardness of the tool, and affect the use of the tool; (2) After the tool is damaged, it can only be cut by flame disassembled in a dismantled way, which not only damages the tool, but also damages the joint surface of the tool seat, resulting in long maintenance time and high maintenance costs; (3) The removed tool cannot be repaired and used because it has been damaged, wasting resources; it also increases cost

(4) To use this tool, the main shaft of the crusher must be processed into a long hexagonal or long spline shape, which has high processing costs, complicated manufacturing processes, and high requirements for materials.
