Furthermore, the diameter of the pressure discharge opening is smaller than that of the inlet so as to be convenient for the proper retention of oxygen in the air tank,
during the use, bury jar body in the blast point, arrange the pressure port and expose, during the ignition, press the ignition button, produce the electric spark in the gas pitcher, by the combustion-supporting of high-purity oxygen in the gas pitcher, gas expansion forms the blasting, pollutes lowly, if the phenomenon of "dumb bullet" appears in addition, can close the valve, treats that the oxygen in the gas pitcher scatters and gets rid of when the purity reduces, safer.
If no water is accumulated in the pit, the tank body can be omitted.
First, after the tank body is buried in a drilled blast hole, it is sealed with yellow mud or cement, and only the inlet pipe and the discharge port are exposed.
Preferably, during air inlet, the power machine of the trolley is closed, the pressure increasing valve is operated by remote pneumatic operation to be opened, then the exhaust valve is opened to carry out automatic inflation, after inflation is carried out, the pressure increasing valve is closed, then the exhaust valve is closed, and then the inflation pipe is recovered by the pneumatic rotating disc. The static spark generated by the contact of a human body with the liquid oxygen bottle is completely avoided, and the automatic pressure discharge function (pressure discharge port) is added, so that the on-site unmanned operation is realized, and the purposes of safe construction, energy conservation and environmental protection are achieved.
Preferably, the invention can be used in a cement supporting beam and a column (pile), the gas tank is pre-embedded in the middle position before the cement beam is poured, an ignition wire and a connecting pipe are led out, and the gas is inflated and started when blasting is needed, and the gas tank can be manually drilled and inflated in a place without pre-embedding.
