Crushing equipment for coal mining

Abstract

The invention relates to the technical field of mechanical equipment, in particular to crushing equipment for coal mining, which is capable of effectively improving the diversity of equipment functions by crushing coal, conveniently performing diversified crushing treatment on the coal, improving the crushing effect of the coal and conveniently enabling the shape of the coal to meet the specified requirement. Meanwhile, the coal is subjected to multi-section crushing treatment, the strength requirement of the coal on equipment can be effectively reduced, the equipment can be conveniently protected, the service life of the equipment is prolonged, and practicability and reliability are improved; the crushing device comprises a crushing barrel, four groups of supporting legs, a lining, an extrusion conical barrel, an extrusion disc and a circular fixed barrel, an opening of the crushing barrel faces upwards, the bottom of the crushing barrel is an inclined surface, the four groups of supporting legs are fixed at the bottom of the crushing barrel, the lining is mounted on the inner wall of the crushing barrel, the top of the lining is a funnel-shaped inclined surface, and the middle of the inner wall of the lining is a conical surface.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a crushing equipment for coal mining. Background technique [0002] As we all know, coal mining production is mainly to mine and process underground coal, so that it can meet the needs of people's normal production and life. After coal is mined, its shape is relatively large. Coal is crushed. When the existing crusher is in use, it mainly relies on the extruding plate in the vibration state to squeeze and crush the coal, so that the shape of the coal is reduced. However, when this equipment is used, the crushing method is relatively simple. There are large objects in the crushed coal, and the crushing effect is poor. At the same time, the extrusion plate in the equipment directly accumulates and crushes the coal, and the operation intensity of the equipment is relatively high, resulting in a low service life of the equipment.

When the existing crusher is in use, it mainly relies on the extruding plate in the vibration state to squeeze and crush the coal, so that the shape of the coal is reduced. However, when this equipment is used, the crushing method is relatively simple. There are large-shaped objects thrown in the crushed coal, and the crushing effect is poor. At the same time, the extrusion plate in the equipment directly accumulates and crushes the coal, and the operation intensity of the equipment is relatively high, resulting in a low service life of the equipment.
