Abstract

The invention relates to the technical field of coal ploughs for exploiting low coal seams in underground coal mines, and particularly relates to a rotary tool apron structure capable of being quickly disassembled and assembled of a coal plough. A plough cutter seat in the prior art is in penetrating connection with a plough body through a long pin, and when the plough cutter seat needs to be replaced, time and labor are wasted during the operation, and the exploiting efficiency of the coal plough is seriously influenced. The rotary tool apron structure consists of a rotary tool apron, a plough body, a long ring, a bolt and a nut, wherein the rotary tool apron is rotated by taking a bearing pin installed on the plough body as a rotating center; when a semicircular hook of the rotary tool apron and a boss extending out of the plough body are arranged in parallel, the long ring is installed and is fixed through the bolt and the nut; and when the bearing pin on the rotary tool apron is rotated in a corresponding position of a guide groove of the plough body, the rotary tool apron can be disassembled along with the guide groove. The rotary tool apron structure is simple and convenient to operate, low in labor intensity and quick in operating speed, and is suitable for underground coal ploughs.

Description

Technical field: [0001] The invention relates to the technical field of coal plows used for mining thin coal seams in underground coal mines, in particular to a quick disassembly and assembly rotary knife seat structure for coal plows. Background technique: [0002] The planer seat is the carrier on which the planer is installed. With the increase of coal plowing, the planer seat is easy to be worn and damaged. For the normal operation of production work, it is necessary to overhaul the planer holder and replace the damaged planer holder in time to avoid delaying coal mining. The planer seat of the existing downhole coal plow is connected with the planer body from top to bottom by a long pin. If the planer seat is damaged and needs to be replaced, considering the narrow working space of the coal plow, the long pin cannot be pulled out, so it is necessary to lift the plow head of the coal plow as a whole for operation. If the height of the coal seam changes, it is required ...
