[0002] A coal mining machine is a key equipment used in underground coal mining. Its performance directly affects the production efficiency and safety of the coal mine. A coal mining machine encoder is a sensor used to measure and record information such as the position, speed, and direction of the coal mining machine during operation. It is usually installed on key components of the coal mining machine, such as drive wheels or crawlers, to ensure that the coal mining machine can operate accurately according to the predetermined path and speed.

[0003] The encoder is an important component of the coal mining machine, which is used to detect the operating status of the coal mining machine. However, the existing coal mining machine encoder installation structure often has the problem of inconvenient maintenance, which brings difficulties to the maintenance of the equipment. Therefore, we propose a coal mining machine encoder installation structure that is easy to maintain to solve the above problem. Utility Model Content
