Abstract

The invention discloses a floor heave crushing machine in a coal mine tunnel and belongs to the technical field of floor heave crushing and cleaning in the coal mine tunnel. In order to solve the technical problems, a transport cart special for the coal mine tunnel and having a hydraulic crushing hammer which can rotate flexibly in multiple directions is provided. A large area of the floor heave can be crushed without enabling the whole rack to rotate, so that working safety is ensured and work efficiency is increased. The adopted technical scheme is that multiple groups of traveling mechanisms are arranged on the lower part of the rack, the back end of the hydraulic crushing device is fixedly arranged on the front part of the rack through a turntable, the back part of the rack is provided with an explosion-proof diesel engine and a hydraulic system both of which provides motive power, the rack is also provided with a console and a driver's seat. The hydraulic crushing device of the floor heave crushing machine is arranged on the front part of the rack through the turntable, a hydraulic motor controls a gear transmission device to realize rotation of the turntable, the direction of the hydraulic crushing device is adjustable, the whole rack is unnecessary to rotate, and the floor heave crushing machine is more flexible to use.

Description

technical field

[0001] The invention relates to a bottom drum crusher in a coal mine roadway, which belongs to the technical field of crushing and cleaning the bottom drum in a coal mine roadway. Background technique

[0002] When mining is not carried out after the tunneling of the coal mine roadway is completed, the bottom surface of the roadway is subjected to various stresses and often has severe bulges and deformations, that is, floor heaves. Common floor drums are about 1.5 meters high and 1.5 to 2 meters in diameter, which seriously affects the excavation work of the next working face. At present, the bottom drum is mainly crushed manually with the help of simple tools, and then the broken coal and rock are loaded on the belt conveyor for cleaning. Therefore, the cleaning speed of the bottom drum is slow with the current process, and the labor intensity of the workers is high, which consumes manpower.

[0003] Now large coal mining enterprises also have simple bottom...
