The invention relates to the technical field of coal mining equipment, and discloses a coal mining splitting machine, which includes a hydraulic pump, the bottom of the hydraulic pump is fixedly equipped with rollers, and one side of the upper surface of the hydraulic pump is fixedly equipped with a handrail. The upper part of one side of the hydraulic pump is fixedly equipped with a hydraulic valve one, one end of the hydraulic valve one is fixedly fitted with an oil pressure pipe, one end of the oil pressure pipe is fixedly fitted with a gun body, and the two sides of the lower surface of the gun body The side slides are fitted with left and right wedges. The splitting machine for coal mining is integrally formed with a stacking groove on the upper part of the left and right wedges, and the stacking groove is set as an upwardly curved groove, so that the crushed coal powder crushed on the surface of the coal mine accumulates in the groove, preventing The crushed coal enters the gap between the left and right wedges and the T-shaped sliding key where the left and right wedges slide along the outer surface of the gun body, causing the problem that the T-shaped sliding key is difficult to slide, ensuring that the equipment is working when tearing the coal mine. Displacement tearing effect for wedges.
Description
technical field [0001] The invention relates to the technical field of coal mining, in particular to a splitting machine for coal mining. Background technique [0002] At present, the construction technology requirements for coal mining are becoming more and more stringent. Therefore, the non-explosive construction method has been widely promoted and applied in coal mining construction. It has the characteristics of safety, environmental protection, and noise reduction. Among them, the use of splitting wedges and The splitting pump expands and tears the coal mine to achieve the crushing of the coal mine, which makes it easier for workers to mine the coal mine. [0003] The existing coal mine splitting machine, in the process of use, first drills the coal mine that needs to be split, inserts the wedge at the lower part of the split gun into the inside of the drill hole, and uses the hydraulic pump to apply pressure to the coal mine through the high and low pressure oil pipes....
