Manual blasting requires drilling the excavated rock, filling it with solid explosives and blasting, and then cleaning the slag before proceeding to the next round of construction. This method can only be manual excavation, and the blasting and drilling are separated. Filling with explosives, blasting is not used in conjunction with rock drilling equipment, the filling process is complicated, which affects the progress of excavation, and the construction efficiency needs to be improved
The automatic rotary drilling adopts chipping arch cutter, and performs physical cutting through the rotation of the blade. Although it is automatic, the effect of physical cutting cannot be compared with that of blasting

The invention provides a fast explosive drilling device which comprises a drill bit. The back end of the drill bit is connected to a flow guiding pipe body, an explosive injection hole is formed in the outer side wall of the back of the flow guiding pipe body in a rock drilling direction, an explosive injection channel is arranged in the flow guiding pipe body in a length direction, the explosiveinjection channel communicates to the explosive injection hole, a front sealing ring is arranged on the outer wall of the front part of the flow guiding pipe body in the rock drilling direction, a back sealing liquid ring is arranged on the outer wall of the back part of the flow guiding pipe body in the rock drilling direction, and the explosive injection hole is located in the front end of the back sealing liquid ring in the rock drilling direction. The fast explosive drilling device can be filled with a liquid explosive for explosion and is good in explosion effect. Explosion and rock drilling can be carried out simultaneously, and the explosive can be filled continuously without taking out a drill bit, so that the explosion efficiency is high.
Description
technical field [0001] The invention relates to a blasting drilling device, in particular to a rapid blasting drilling device. Background technique [0002] At present, in the construction of tunnels such as railways, highways, subways, and mountain drilling, two excavation methods, manual blasting excavation and automatic rotary knife cutting, are often used for construction. Manual blasting requires drilling the excavated rock, filling it with solid explosives and blasting, and then cleaning the slag before proceeding to the next round of construction. This method can only be manual excavation, and the blasting and drilling are separated. Filling with explosives, blasting is not used in conjunction with rock drilling equipment, the filling process is complicated, which affects the progress of excavation, and the construction efficiency needs to be improved. Automatic rotary drilling uses chipping arch cutters, which perform physical cutting through the rotation of the bla...
