Abstract

The invention discloses a crushing loading roadway repairing machine for a coal mine. A body part comprises a workbench, a drive device, a walking device and an oil tank; an execution mechanism mainly comprises an excavation arm and an operation head; a revolving device is arranged between the excavation arm and the workbench; the excavation arm comprises a big arm, a small arm and a movable arm; a breaking hammer is mounted in the small arm, and a movable arm oil cylinder is arranged above the small arm; the movable arm oil cylinder is communicated with an oil way control valve of the execution mechanism through a central joint and an oil pipe; a big arm oil cylinder I and a big arm oil cylinder II are communicated with an oil way control valve of a control device through the central joint and the oil pipe; the drive device is a hydraulic drive device; the hydraulic drive device comprises an explosion-proof motor and an oil pump; an output end of the explosion-proof motor is in transmission connection with an output shaft of the oil pump through a coupling; an output port of the oil pump is communicated with an input port of a control valve through an oil way; the oil way control valve is a pilot multi-way valve; the pilot multi-way valve is arranged on a bracket of the workbench; and an operation handle of the pilot multi-way valve is arranged above the bracket.

Description

technical field [0001] The invention relates to a crushing and loading roadway maintenance machine for coal mines. Background technique [0002] The current vertical and horizontal rotation of the current crushing and loading roadway maintenance machine for coal mines uses a torque transmission box. The rack and gear in the transmission box are driven by a hydraulic source and an oil cylinder to achieve rotation. During rotation, there is a gap between the gear and the rack. , a deflection phenomenon occurs during rotation. When replacing the breaking hammer, because the breaking hammer is relatively heavy, it will bring great inconvenience to the construction personnel when replacing it. The oil pipes supplied by the multi-way valve to the bucket, breaking hammer, large and small arms, and the rotary transmission box are hung on both sides and are easily damaged. Contents of the invention [0003] The invention relates to a crushing and loading roadway repairing machine...
