A crawler walking self-rotating two-way drilling coal mining machine and its use method

Abstract

Provided are a tracked walking, self-rotating bidirectional drilling coal mining machine and an application method thereof. The coal mining machine comprises a coal mining machine upper frame assembly (2) and a coal mining machine base (3) provided under the coal mining machine upper frame assembly (2). A rotary supporting device (4) is provided under the coal mining machine base. A tracked walking mechanism (6) is provided under the rotary supporting device (4). A transmission device (5) connected to the rotary supporting device (4) is provided on the tracked walking mechanism (6). The drilling coal mining machine disposed in a roadway firstly mines one side of a thin seam, rotates by 360° by controlling the rotary supporting device (4) after finishing mining the thin seam on the side, and mines the other side after the rotary supporting device (4) rotates to the other side of the thin seam, thereby allowing a screw drilling machine to bidirectionally mine coal at the same site without moving the equipment greatly, thus improving mining efficiency. In addition, when a crossing appears en route from a main roadway to a working face roadway, a screw bit can self-rotate, thus easily passing through the roadway crossing to reach a working face and saving on equipment moving time.

Description

technical field [0001] The invention relates to a two-way drilling coal shearer and a use method thereof, in particular to a crawler walking and self-rotating two-way drilling coal shearer suitable for the drilling coal shearer and a use method thereof. Background technique [0002] The auger coal mining method is a relatively mature coal mining method in unmanned coal mining face. Mining and recovery of various coal pillars. However, at present, due to the fact that the drill shearer only has the function of unidirectionally mining the coal seam during the thin coal seam mining process, the existing auger shearer cannot realize simultaneous mining when there are thin coal seams on both sides of the roadway. For mining, one side needs to be mined and then transferred to the other side for mining. The whole process results in low excavation efficiency, time-consuming and labor-intensive work, high labor intensity for workers, and increased coal mining time and equipment movi...
