Mobile crushing and multi-screening equipment based on coal mining

Abstract

The invention provides movable crushing and multi-screening equipment based on coal mining, and relates to the technical field of coal mining equipment, the movable crushing and multi-screening equipment comprises a main body, wheels are mounted at the bottom of the main body, and a feeding mechanism is mounted at the top of the main body; a feeding opening in the feeding mechanism is formed in the top of the charging barrel, the bottom of the outer side of the feeding opening is connected with the side face of the top of the main body through a supporting rod, and a baffle in the feeding mechanism is installed on the inner side of the feeding opening through a rotating shaft; the screening part is installed in the charging barrel, and a flow guide plate in the screening part is installed on the side face of the charging barrel. The cover plate and the baffle are used for blocking coal splashing in the crushing process, the coal is prevented from splashing to other places, safety is improved especially when workers stay around, and the problem that when existing crushing multiple-screening equipment is used, the coal is crushed, and the working efficiency is high is solved. And the problem that the crushed coal is easy to splash to other places due to large crushing force is solved.

Description

technical field [0001] The invention relates to the technical field of coal mining equipment, in particular to a mobile crushing and multiple screening equipment based on coal mining. Background technique [0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. In the process of mining, coal mines use mobile crushing and multiple-screening equipment to crush large pieces of coal, and classify them according to the size of the coal, which is convenient for coal to be applied to. different usage occasions. [0003] However, when the existing crushing and screening equipment is used, the coal is crushed, and the crushing force is large, and the crushed coal is likely to splash to other places, and when the crushed coal is screened, the sieve holes The size of the coal is relatively fixed, so that the classification of coal screening is relatively single, and the applicability to the coal size required by different occasions is poor. SUMMARY O...
