Self-moving feeding crusher

Abstract

The invention relates to a self-moving feeding crusher, which mainly comprises a frame, a material receiving mechanism, a coal cleaning mechanism, a crushing mechanism, a discharging mechanism, a walking mechanism, a cab, an electric control box, a hydraulic pump station, an oil tank, a crushing motor, a speed reducer, a torque limiting device and an illuminating lamp. Due to the adoption of a design for combining material receiving, crushing, conveying, discharging and walking, the entire crusher can be transported and assembled separately; the entire crusher has the advantages of advanced and reasonable design, compact structure, convenience for installing and using, safety, stability, reliability, good crushing effect and high efficiency; compared with the prior art, the crusher has the advantages that the efficiency can be increased by 90 percent; and the self-moving feeding crusher is very ideal.

Description

technical field [0001] The invention relates to a self-moving feeding crusher, which belongs to the technical field of supporting equipment in underground coal mines. Background technique [0002] In the mechanized operations of continuous coal mining in coal mines, many mechanized equipment are used, such as continuous coal mining machines, bolters, shuttle cars, and belt conveyors, to realize the mechanization of coal dropping, coal loading, support, crushing, and transportation During operation, there are many large lumps of coal in the mined coal. These large lumps of coal seriously hinder the transfer and transportation of coal. Therefore, the large lumps of coal must be mechanically crushed to meet the rapid transportation of belt conveyors. [0003] At present, the feeding crushers used all adopt the overall frame structure, and the frame and the traveling mechanism are connected by a single-turn hinge pin and a lifting cylinder. This structure prevents the material r...

Problems solved by technology

[0003] At present, the feeding crushers used all adopt the overall frame structure, and the frame and the traveling mechanism are connected by a single-turn hinge pin and a lifting cylinder. This structure prevents the material receiving and lifting from being realized at the same time. The material part is lowered, and when the discharge part is raised, the material receiving part is lowered, which is similar to the seesaw structure, so that the discharge height is severely limited, so when the discharge part is raised to match the height of the belt conveyor When working, it is often necessary to place sleepers under the crawler walking mechanism to raise the height of the whole machine, which seriously restricts the operational flexibility of the crusher.
