Description

Auxiliary manufacturing device for blasthole stuffing Technical Field The utility model relates to the technical field of mechanical equipment, in particular to an auxiliary manufacturing device for a blast hole filler. Background In the field of hard rock engineering excavation, a drilling and blasting method is a traditional and widely applied construction method. The core aim is to crush rock efficiently and accurately so as to promote engineering progress and ensure construction quality. However, the effective utilization of the explosive energy is always a key factor limiting the construction effect and cost of the drilling and blasting method. Numerous studies have shown that blasthole packing is critical to improving explosive energy utilization. The blast hole filling can effectively increase the propagation energy of stress waves, and promote the inside of the rock to generate more and longer radial cracks, thereby obviously improving the blasting effect. In contrast, if the blast hole is not plugged, explosive gas can quickly escape through the hole opening, about 50% of explosive energy is taken away, energy waste is caused, meanwhile, the rock breaking degree and the blasting quality are influenced, and engineering cost and time cost are increased. In the manufacturing process of the blast hole stuffing, a sucker is selected to adsorb the sealing plug, and then the sealing plug is moved and plugged into the PVC pipe, so that the PVC pipe is sealed. When the sucker is separated from the sealing plug, water in the underwater environment can obstruct gas circulation, the vacuum cavity formed after pressing cannot suck air, and the external water pressure continuously enhances the adsorption force, so that the sealing plug is locked on the sucker, and the sealing plug is damaged or deformed by external force, thereby damaging the sealing integrity of the PVC pipe. Disclosure of utility model Aiming at the defects in the prior art, the utility model provides an auxiliary manufacturing device for a blast hole filler, which is used for solving the problems that when a sucker and a sealing plug in the prior art are separated, water in an underwater environment can obstruct gas circulation, a vacuum cavity formed after pressing cannot suck air, the external water pressure continuously enhances the adsorption force, so that the sealing plug is locked on the sucker, and the sealing plug is damaged or deformed by external force, so that the sealing integrity of a PVC pipe is damaged. In order to achieve the aim, the auxiliary manufacturing device for the stemming comprises a power source, a connecting rod, a mounting cylinder and a sucker, wherein the moving end of the power source is connected with the connecting rod, one end of the connecting rod is slidably connected in the mounting cylinder, the tail end of the mounting cylinder is fixedly connected with the sucker, and the sucker is used for adsorbing a sealing plug; The connecting end of the sucker and the mounting cylinder is provided with vent holes, the tail end of the connecting rod is fixedly connected with a sealing pad used for sealing the vent holes, the inner wall of the mounting cylinder is provided with a sliding groove, the connecting rod is fixedly connected with a sliding block matched with the sliding groove, the sliding block is slidably connected in the sliding groove, a first spring is arranged between the sliding groove and the sliding block, one end of the first spring is fixedly connected with the inner wall of one end of the sliding groove away from the sucker, and the other end of the first spring is fixedly connected with the sliding block. The device is arranged in such a way, water enters the sucker along the vent hole through the relative sliding between the connecting rod and the mounting cylinder, so that the purpose of separating the sucker from the sealing plug is achieved easily and quickly, and the elastic deformation of the first spring is utilized to reset the connecting rod and the mounting cylinder so as to be used next time. Further, the device also comprises a water injection tank and a positioning channel, wherein the positioning channel is fixedly arranged on one side of the water injection tank, the movable end of the power source penetrates through one side of the water injection tank and is positioned in the positioning channel, and the movable end of the power source is fixedly connected with one end, away from the mounting cylinder, of the connecting rod.
