The invention discloses a blasthole blockage dredging device, and belongs to the technical field of blasting. The blasthole blockage dredging device comprises a switch, a spring, a pressing rod, an elastic piece, a pushing rod and the like; the switch is located on a main rod body, the pressing rod is arranged below the switch and sleeved with the spring, the lower end of the pressing rod makes contact with the elastic piece, the elastic piece is fixed to the tail end of the pushing rod, the other end of the pushing rod makes contact with a protrusion on a bearing, the bearing is arranged on ashaft II in a sleeving manner, the shaft II is fixed to the main rod body, and a restraining mechanism is fixed to the bearing; an inward extending part is arranged at the tail end of the restrainingmechanism and used for clamping a lifting plate, the lifting plate is located on the main rod body, the lifting plate is connected with the main rod body through a shaft III, and the lifting plate rotates along the main rod body; and a rock breaking mechanism is arranged at the tail end of the main rod body, and the tail end of the rock breaking mechanism is of a needle-point-shaped structure. According to the blasthole blockage dredging device, material waste can be reduced, the labor cost is saved, the working efficiency is improved, and the blast hole state is not changed.
Description
technical field [0001] The invention relates to a device for dredging blast hole blockage, which belongs to the technical field of blasting. Background technique [0002] Blast hole filling is one of the important processes in blasting operations. The purpose of filling is to make good use of the energy of explosive explosion and improve the fragmentation effect of rock blasting. And in the mine blasting process, due to the negligence of the workers, the rock blocks around the blast hole often fall into the blast hole, thereby causing the blast hole to be blocked. If effective treatment is not carried out, it will be difficult to charge the blast hole. The traditional treatment method of mine construction personnel is to use gun sticks to press the rocks blocking the blast hole into the bottom of the hole. When the blockage is serious, this method has poor applicability and cannot achieve the expected effect. When there are many rocks pressed into the bottom of the hole , w...
