Description

technical field [0001] The invention relates to the field of machinery, in particular to a control mechanism for a rocker arm of a multi-link shearer. Background technique [0002] The coal shearer is a large complex system integrating machinery, electricity and hydraulic pressure, and the working environment is harsh. If a failure occurs, the entire coal mining work will be interrupted, resulting in huge economic losses. 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. The main working part of the shearer is the drum. When mining coal in the coal mine, the shearer mainly relies on the drum to complete the coal mining work. Drum shearers are suitable for use under the conditions of small changes in coal seam thickness, no rock inclusions, simple geological structures, and easy roof ...
