Drilling and planing coal mining machine plow head

Abstract

The invention provides a drilling and plowing type coal winning machine plow head which comprises a coal plowing device; the coal plowing device is composed of a plane cutter, cutter seats, a planing body which has an asymmetric structure and a coal drilling device; the cutter seats on the left and right sides are arranged in a staggering manner; the coal drilling device is composed of four explosion-proof motors and four conical drills; the explosion-proof motors are arranged in the planing body; the output ends of the explosion-proof motors are directly connected with the conical drills respectively; and the conical drills are arranged on the left and right sides of the planing body in the staggering manner. The drilling and plowing type coal winning machine plow head can effectively lower the coal plowing difficulty, greatly improves the coal plowing efficiency, can effectively solve the problem of mining thin coal seams with large hardness and no joint development, greatly improves the mining efficiency of the thin coal seams and is wide in application range.

Description

technical field [0001] The invention relates to a thin coal seam drilling and planing type coal cutting method, in particular to a drilling and planing type coal shearer plowing head, which is especially suitable for rapid mining of thin coal seams underground in coal mines. Background technique [0002] my country's thin coal seam reserves are abundant and widely distributed. The thin coal seam reserves of national coal mines are more than 6 billion tons, but the output is only 10.4% of the total output. As time goes by, medium-thick and thick coal seam resources will gradually be exhausted, and thin coal seam mining will become an inevitable trend. [0003] At present, the more commonly used thin coal seam mining equipment in China mainly includes coal plows and drilling shearers. However, traditional coal plows and coal drills are mostly used for mining coal seams with low coal seam hardness and well-developed joints and fissures. For the mining of coal seams with high...
