Abstract

The invention relates to mining equipment, in particular to a tunneling mechanism for coal mine. The tunneling mechanism comprises a frame, a motor, a spiral digger, a bearing, sliding blocks, a fixing plate and a propulsion device, wherein the frame comprises a support and a front prop; digging pieces are arranged on the spiral digger, the spiral digger penetrates through a bearing inner ring and is mounted on a shaft of the motor, and the propulsion device is connected with the motor through the fixing plate; the sliding blocks are arranged on the two sides of the bearing, the motor and the fixing plate, are mounted on sliding grooves in the frame, and can do reciprocating motion relative to the frame. During in use, as the front prop can avoid swing of the digger in the digging process, the tunneling mechanism is safe and reliable, and manpower can be effectively reduced. As the bearing is sleeved with the spiral digger, the damage of the shaft of the motor is reduced, and the service life of the motor is prolonged.

Description

technical field [0001] The invention relates to mining equipment, in particular to a mining driving mechanism. Background technique [0002] At present, the mining excavation equipment mainly includes a motor and a saw blade. The saw blade is in the shape of an arc, with sawtooth on one end of the arc, and the other end is fixedly connected with the motor shaft. The excavating device with this structure is relatively heavy, easy to swing, low in excavating efficiency, and easy to damage the motor shaft. Contents of the invention [0003] In view of the above problems, the present invention provides a mining tunneling mechanism with high excavation efficiency, safety and reliability, and the specific technical scheme is as follows: [0004] The mining excavation mechanism includes a frame and a motor, and the frame includes a bracket, a front support and a chute; the bracket is installed on the outside of the frame for connecting the support frame; the front support is fix...
