The invention relates to the technical field of coal mining equipment and discloses a splitting machine for coal mining. The splitting machine comprises a hydraulic pump, wherein a rolling wheel is fixedly mounted at the bottom of the hydraulic pump; a handrail is fixedly mounted on one side of the upper surface of the hydraulic pump; a hydraulic valve I is fixedly mounted at the upper part of oneside of the hydraulic pump; an oil pressure pipe is fixedly mounted at one end of the hydraulic valve I in a sleeving manner; a gun body is fixedly mounted at one end of the oil pressure pipe in a sleeving manner; and left and right wedge blocks are mounted on two sides of the lower surface of the gun body in a sliding manner. According to the splitting machine for coal mining, an accumulating groove is integrally formed at the upper parts of the left and right wedge blocks, besides, the accumulating groove is set as a groove bending upwards, so that pulverized coal extruded and broken on thesurface of a coal mine is accumulated in the groove, the problem that a T-shaped sliding key is difficult to slide because crushed coal enters seams between the left and right wedge blocks and the T-shaped sliding key of the gun body along outer surfaces of the left and right wedge blocks is solved, and the displacement tearing effect of the left and right wedge blocks in a coal mine tearing workprocess by the equipment is guaranteed.
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....
