A coal shearer that is not easy to jam

Abstract

The invention discloses a coal shearer which is not easy to jam, which comprises a machine body, an engine is fixedly connected to the front of the machine body, a rotating plate is sleeved on the output end of the engine, and the rotating plate is away from the side of the output end of the engine A push plate is movably connected, the side of the push plate away from the rotating plate is movably connected with the middle part of the front of the slide plate, the back of the slide plate is fixedly connected with the front of the slider through a connecting rod, and the slider is slidably connected to the fixed plate In the set slide rail, the back side of the fixing plate is fixedly connected with the front side of the machine body. The coal shearer that is not easy to get stuck has achieved the effect of pushing the slider to slide in the slide rail by setting the slide plate. By setting the slide plate, the two curved plates can move up and down and expand outward, and the spring With the cooperation of the two curved plates, the pulling and pushing teeth on the top of the two curved plates can always mesh with the pick. When the curved plate drives the pulling and pushing teeth to move up and down or left, the pick is 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 easily stuck. Background technique [0002] 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 high output, high efficiency, and low consumption. However, a coal shearer is a large and complex system integrating machinery, electricity, and hydraulic pressure. When touching strong stones or other strong objects during operation, it will cause the jamming phenomenon, 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. Contents of the invention [0003] The purpose of the present invention is to provide a coal shearer that is not easy to get stuck, so as to solve the problems r...
