Claims

[Scope of utility model registration request]

In an explosive loading device, a loading tube is inserted into a blast hole drilled in a rock, and the explosive is loaded by air through the loading tube into the blast hole. An explosive guide hole extending axially within the device main body and leading to the loading tube in order to guide the explosive from the device main body to the loading tube; In the middle part of the hole, there is an explosive supply hole extending radially outward so as to open from the explosive guide hole to the outside of the machine, and is provided at the rear of the explosive guide hole in the device main body, so that the piston can be moved in the front and back direction. a cylinder for extruding explosives built into the cylinder; a spring that always biases the piston in the backward direction; A rod 1 that opens the explosive supply hole so that the explosive can be supplied and closes the explosive supply hole so that the supply cannot be performed when the piston moves forward; an air supply hole formed in the rod and communicating with an air source; an air injection path formed in the rod so as to communicate with the air supply hole and inject air from the tip of the rod only when the piston moves forward; An explosive loading device comprising a switching valve that can take a first position in which the working chamber at the rear of the piston is communicated with an air source and a second position in which it is opened to the atmosphere.
