Problems solved by technology

Although the tunneling technology has greatly improved the tunneling speed of the working face, a large amount of coal dust will be generated at the head-on position during the process of tunneling the coal seam by the roadheader, which seriously threatens the personal safety of underground workers in the coal mine and affects the safe production of the mine. , is not conducive to the steady development of mining enterprises, so it is necessary to design a coal mining face excavation crushed coal conveying equipment to improve the above problems

Abstract

The invention relates to the technical field of coal mine equipment, in particular to coal mine working face tunneling crushed coal conveying equipment which comprises a machine body, a left-right extending lifting cavity with a rightward opening is formed in the machine body, a feeding cavity with a leftward opening is formed in the lifting cavity in a leftward communicating mode, and a shovelingplate is arranged on the left end wall of the machine body in a vertical sliding mode. Lifting air cylinders are fixedly arranged at the left end of the machine body in a front-back symmetry mode, and the lower ends of the lifting air cylinders are fixedly connected with the shovel connecting plate. The tunneling drill bit rotates at a high speed to excavate coal from the working face, the coal is collected by the star plate and then lifted to the conveying belt, and the coal can finally reach the belt conveyor after passing through the reversed loader for auxiliary transportation and is conveyed into the coal bunker by the belt conveyor. Workers do not need to enter a working face for operation, and potential safety hazards of the workers are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of coal mine equipment, in particular to a coal mine working face excavation crushed coal conveying equipment. Background technique [0002] Petroleum, coal, and natural gas are the three main energy sources in modern society. Among them, the existence of coal plays a vital role in promoting the development of industry and provides abundant energy for social survival. The tunneling operation of fully mechanized excavation working face is a crucial step in mining coal, and the selection of various equipment in the working face is also the key to mine safety production. [0003] At present, roadheaders have been widely used in coal mines in my country. Although the tunneling technology has greatly improved the tunneling speed of the working face, a large amount of coal dust will be generated at the head-on position during the process of tunneling the coal seam by the roadheader, which seriously threatens the ...
