Abstract

The invention discloses a shifting fork assembly for a coal mining machine. The shifting fork assembly comprises a rocker arm, a shifting fork shaft, a shaft seat, a shaft telescopic regulation connecting rod, a rocker arm fixed part and a wear-resistant antiskid rocker arm lantern ring, wherein the rocker arm is arranged on the shifting fork shaft through the wear-resistant antiskid rocker arm lantern ring and is fixed through the rocker arm fixed part, the shaft seat is arranged at an opening of one end of the shifting fork shaft, and the other end of the shifting fork shaft is connected with the shaft telescopic regulation connecting rod. Through the mode, the shifting fork assembly is firmly combined, and has small possibility of abrasion, the length of the shifting fork shaft is conveniently regulated, so that the use is very convenient.

Description

technical field [0001] The invention relates to the field of coal shearer accessories, in particular to a shift fork assembly for a coal shearer. Background technique [0002] The task of the shearer is to cut coal, salt mine, ore, other minerals and their gangue, and the shearer can cut in both directions. Depending on the diameter of the cutting drum and the installation height of the shearer, the shearer can be used to cut seams of different hardness. [0003] Shearer is the main production tool of coal mine mechanized mining. Its operation status and efficiency mark the level and capacity of coal mine production, and play an important role in coal mine production. During the use of the shearer, due to the production environment, physical wear, and use conditions, etc., the shearer must be inspected, maintained and repaired to meet the needs of coal mine production for the shearer. [0004] However, the combination of the current fork assembly used in the shearer is not...
