Abstract

The invention discloses a coal cutter rocker arm. The rocker arm at least comprises: a cutting biaxial assembly, a cutting triaxial assembly, a first dual gear and a second dual gear, wherein the first dual gear is connected with the cutting biaxial assembly, and the second dual gear is connected with the cutting triaxial assembly; and a speed regulation mechanism, wherein the speed regulation mechanism at least comprises a slip gear, a pull bar, a handle and a stopping device, the slip gear is connected with the pull bar and can slip on the cutting biaxial assembly, the pull bar is connected with the handle, and the handle is fixed at different positions of the stopping device through stretching. The coal cutter rocker arm can realize the transformation of the rotating speed of a rocker arm roller through the operation of the speed regulation mechanism, and has a convenient and fast operation and a strong practicality.

Description

technical field [0001] The invention relates to a rocker arm of a coal shearer, in particular to a rocker arm of a coal shearer capable of rapidly changing the rotational speed of a drum. Background technique [0002] At present, in order to adapt to the different conditions of the coal seam, it is necessary to change the diameter of the drum of the shearer during the coal mining process. Correspondingly, in order to achieve the best force and use effect of the drum after the diameter change, the speed of the drum also needs to be changed. The rocker arm of the shearer commonly used in the prior art usually has only one drum speed. In order to achieve the purpose of changing the drum speed, it is necessary to disassemble the transmission part of the rocker arm and replace the transmission gear. The above operation process is complicated and it is difficult to ensure the installation accuracy. , and it is easy to contaminate the lubricating part of the rocker arm. Contents ...
