Explosive charging device

Abstract

The invention discloses an explosive charging device. The explosive charging device comprises a hopper, a rotor, a bottom plate, a mounting plate and an air channel, wherein the hopper used for containing explosives is mounted at the upper end of the mounting plate; the bottom plate is arranged below the mounting plate; the rotor is mounted between the mounting plate and the bottom plate, a rotating shaft mounting cavity is formed in the middle of the rotor, and a rotating shaft is mounted in the rotating shaft mounting cavity; a driving assembly is in transmission connection to the rotating shaft; rotor material cavities are further formed in the rotor; an explosive outlet is formed in the bottom of the hopper, and a discharging opening is formed in one side of the bottom plate. The rotormaterial cavities can communicate with the explosive outlet and the discharging opening in the rotating state of the rotor, a rotational flow elbow is mounted at the bottom end of the discharging opening, a first air inlet is formed in the side wall of the rotational flow elbow, and the air channel communicates with the first air inlet through a pipeline. The rotor rotates to isolate the explosive outlet of the explosives from the discharging openingcommunicating with an air passage, so that high-pressure air is prevented from entering the hopper from a discharge channel, and continuous adding and charging of the explosives are realized.

Description

technical field [0001] The invention relates to the technical field of ore mining, in particular to an explosive charging device. Background technique [0002] With the impact of factors such as environmental protection and mineral rich deposits, mines are gradually developing underground, and the amount of explosives used for upward holes in the underground is increasing. The explosives for underground upward holes are now mostly charged by compressed air, that is, manually loaded by pneumatic chargeers. Explosives, the basic principle is a conical tank, the feeding port is sealed after adding the drug, the high-pressure air is introduced, the discharge port from the bottom is opened, and the explosives are transported to the blast hole through the feeding pipe to adhere to them. During the operation of the equipment , for intermittent feeding, the compressed air in the tank needs to be released each time the drug is charged, and then the drug is charged and pressurized, re...

[0002] With the impact of factors such as environmental protection and mineral rich deposits, mines are gradually developing underground, and the amount of explosives used for upward holes in the underground is increasing. The explosives for underground upward holes are now mostly charged by compressed air, that is, manually loaded by pneumatic chargeers. Explosives, the basic principle is a conical tank, the feeding port is sealed after adding the drug, the high-pressure air is introduced, the discharge port from the bottom is opened, and the explosives are transported to the blast hole through the feeding pipe to adhere to them. During the operation of the equipment , for intermittent feeding, the compressed air in the tank needs to be released each time the drug is charged, and then the drug is charged and pressurized, resulting in low charging efficiency. Noise pollution, gas release will blow up dust on site and cause dust pollution, which is not conducive to on-site operation, and can only be used for upward hole charging of viscous explosives
