The replacement device includes a slide plate, which is slidably connected to one side of the machine arm, and the soil-breaking barrel is rotatably connected to a clamping plate on the side close to the slide plate. The soil-breaking barrel is fixedly connected to a positioning spring on the side close to the clamping plate, and the positioning spring is fixedly connected to the clamping plate on the side away from the soil-breaking barrel. A groove is provided on one side of the slide plate. This utility model solves the problem that most of the existing coal mine machinery drums are usually welded and fixed. When the soil-breaking barrel is damaged, it cannot be disassembled in time for quick replacement, resulting in the coal mine machinery being unable to operate normally, affecting the subsequent steps, and causing economic losses to users.

[0004] However, although this disassembly and assembly device can conveniently disassemble and assemble the coal mine machinery drum, the adjustable spacing between the two sets of machine arms is not high, and the installation convenience of drums of different lengths is not high.
