Tracked walking self-rotating bidirectional drilling coal mining machine and application method thereof

Abstract

The invention discloses a tracked walking self-rotating bidirectional drilling coal mining machine and an application method thereof. The coal mining machine comprises an upper frame assembly and a base arranged under the upper frame assembly. A rotary supporting device is arranged under the base. A tracked walking mechanism is arranged under the rotary supporting device. A transmission device connected with the rotary supporting device is arranged on the tracked walking mechanism. The drilling coal mining machine arranged in a roadway exploits one side of a thin seam, rotates by 360 degrees through controlling the rotary supporting device after the exploiting of the thin seam on the side, and exploits the other side after the rotary supporting device rotates to the other side of the thin seam, thereby allowing a screw drilling machine to bidirectionally mine coal at the same site without large moving equipment and greatly improving exploiting efficiency. In addition, when meeting a crossing on the way from a main roadway to a work face roadway, a screw bit can self-rotate, thus easily passing through the roadway crossing to reach a work face and saving 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...
