[0002] Blasting engineering refers to the process of excavating rocks and mineral deposits, demolishing buildings and other related operations with the help of explosives. Before blasting, it is necessary to use a drilling device to dig holes in the rock or mineral deposit. The operator places explosives in the holes to achieve the purpose of crushing. At the same time, drilling can more effectively transmit the energy generated by the explosion to the rock or mineral deposit, increasing the effective range and strength of the blasting.

[0031] The operator moves the bracket 1 to the designated drilling position of the mine where blasting is required through the brake universal wheel 103, then aligns the drill bit 205 with the drilling point, and then nails the fixing nail 104 into the ground to fix the bracket 1 to prevent the bracket 1 from shaking during drilling and affecting the drilling effect, and then starts the motor 203 to drive the mounting sleeve 204 and the drill bit 205 to rotate, and starts the second electric push rod 201 to drive the movable plate 202 to move downward. When the movable plate 202 moves downward, it drives the high-speed rotating drill bit 205 to move downward to drill holes in the mine to complete the blasthole operation, which is convenient for the operator to place explosives in the blasthole to achieve the purpose of crushing. Since the drill bit 205 is a high-wear tool and needs to be replaced regularly, the operator can remove the drill bit 205 from the mounting sleeve 204 for replacement by rotating and removing the fixing bolts 206 and nuts 207.
