Coal mining machine difficult to lock

Abstract

The invention discloses a coal mining machine difficult to lock, which comprises a body, wherein the front of the body is fixedly connected with an engine; the output end of the engine is sleeved with a rotating plate; one side, far away from the output end of the engine, of the rotating plate is movably connected with a push plate; one side, far away from the rotating plate, of the push plate is movably connected with the middle part of the front of a slide plate; the back of the slide plate is fixedly connected with the front of a slide block through a connecting rod; the slide block is in slide connection in a slide rail arranged on a fixing plate; and the back of the fixing plate is fixedly connected with the front of the body. According to the coal mining machine difficult to lock, by arranging the slide plate, the effect of pushing the slide block to slide in the slide rail is achieved; by arranging the slide plate, two bent plates can move up and down and expand outwards, and under the matching of a spring, pull teeth and push teeth at the tops of the two bent plates can be meshed with cutting teeth all the time; and when the bent plates drive the pull teeth and push teeth to move up and down or left and right, the cutting teeth are driven to rotate.

Description

Technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a coal shearer that is not easy to jam. Background technique [0002] The shearer is one of the important equipment to realize the mechanization and modernization of coal mine production. Mechanized coal mining can reduce physical labor, improve safety, and achieve the goals of high output, high efficiency, and low consumption. However, the shearer is a large and complex system that integrates mechanical, electrical and hydraulic pressures. The working environment is harsh. When you touch a strong stone or other strong object during operation, it will cause the phenomenon of machine jam, which will lead to the interruption of the entire coal mining work and cause huge economic losses. For this reason, we have introduced a machine that is not easy to jam Shearer. Summary of the invention [0003] The object of the present invention is to provide a coal shearer that is not...
