Abstract

The invention belongs to the technical field of coal cutters, and particularly relates to a mining coal cutter. The mining coal cutter comprises rotating wheels, wherein the rotating wheels are connected by rotating shafts; two supporting blocks are bilaterally symmetrically arranged on each rotating shaft; transverse plates are mounted on the supporting blocks; four air cylinders are arranged onthe transverse plates; fixing plates are mounted on piston rods of the air cylinders; mounting plates and vertical plates are sequentially arranged on the transverse plates from left to right; transmission gears are mounted at the upper ends of the mounting plates, and driven by a first motor at the rears of the mounting plates; transmission chains formed by articulation of a plurality of slidingblocks are arranged on the transverse plates; teeth are arranged at the upper ends of the sliding blocks; the teeth on the sliding blocks are engaged with the transmission gears; a second motor is arranged at the right ends of the fixing plates, and drives screw rods to rotate; sliding covers are slidingly mounted at the left ends of the fixing plates; a third motor is arranged at the right ends of the sliding covers, and drives hinge rods to rotate; grooves are formed at the right ends of the hinge rods; convex blocks corresponding to the grooves are arranged at the left ends of the hinge rods and an output shaft of the third motor; and U-shaped blocks supporting the hinge rods are arranged on the sliding covers.

Description

technical field [0001] The invention belongs to the technical field of coal mining machines, in particular to a mining coal mining machine. Background technique [0002] Shearer is a more effective coal mining equipment for mining coal seams. It can realize mechanized mining of working faces and reduce labor intensity of workers. It has been popularized and applied in the mining of medium-thick and thick coal seams in my country. When mining a coal seam, sometimes it is necessary to drill a horizontal mine hole on the coal seam, but the existing shearer usually cannot drill a deeper horizontal mine hole, which makes it difficult to carry out the coal mining work and makes the subsequent coal mining more efficient. Affected, how to effectively drill deeper mine holes, this problem needs us to solve. Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the present invention proposes a coal shearer for mining. The invention is mainly...
