Problems solved by technology

[0002] At present, for the mining of coal mines, not only coal lumps will be mined, but also a lot of coal dust will inevitably appear during mining. At present, coal lumps and coal dust are generally transported to the conveying equipment for transportation. Sorting will be carried out in the subsequent use, which will not only affect the ex-factory price of coal and pulverized coal when conveying on the conveying equipment, but also cause environmental pollution, causing dust to fly and affecting the social environment

Abstract

The invention discloses a composite type efficient coal mining machine with a pre-screening function. Screening and separating of coal briquettes and pulverized coal can be realized while a coal layeris conveyed after being mined, so that follow-up pulverized coal and coal briquette transportation is guaranteed, and therefore, pulverized coal can be directly put in special conveying equipment, adverse effects generated on environment by the pulverized coal are reduced, and environment friendliness of coal mining is guaranteed. The composite type efficient coal mining machine is convenient forconveying the pulverized coal and the coal briquettes to a corresponding manufacturer after separating the pulverized coal from the coal briquettes, guarantees mining efficiency and conveying reliability of the mining machine, and improves screening ability.

Description

technical field [0001] The invention specifically relates to a compound high-efficiency coal mining machine with a pre-screening function, belonging to the technical field of coal mining equipment. Background technique [0002] At present, for the mining of coal mines, not only coal lumps will be mined, but also a lot of coal dust will inevitably appear during mining. At present, coal lumps and coal dust are generally transported to the conveying equipment for transportation. Sorting will be carried out in the subsequent use, which will not only affect the ex-factory price of coal lumps and pulverized coal when transported on the conveying equipment, but also cause environmental pollution, causing dust to fly and affecting the social environment. Contents of the invention [0003] The object of the present invention is to provide a compound high-efficiency coal mining machine with pre-screening function to solve the problems raised in the above-mentioned background technol...
