DRILLING AND BLASTING TUNNELING MACHINE Russian patent published in 2018 - IPC E21D9/10 

FIELD: machine building.

SUBSTANCE: invention relates to tunneling machines, in particular to a drilling and blasting tunneling machine. Drilling and blasting tunneling machine contains a drilling and blasting device, an angle adjustment device, a telescopic reciprocating machine and a cantilever type tunneling machine. Drilling and blasting device is mounted on a reciprocating component of a reciprocating telescopic device by means of an angle adjustment device. In this case, the reciprocating telescopic device is installed on a cantilever type tunneling machine. Drilling and blasting device contains a fastening support, as well as a drilling component and an explosive component rigidly mounted on the mounting support, respectively. Angle adjustment device comprises an installation base, an auxiliary rotary hydraulic motor, an adjusting hydraulic cylinder and a main rotary hydraulic motor. And when the reciprocating component of the reciprocating telescopic device is fully extended, the distance from the front end of the drilling and blasting device to the working plane is less than the distance from the front end of the cutting head of the cantilever type tunneling machine to the work plane.

EFFECT: technical result consists in increasing the efficiency of penetration, creating a compact machine design with the ability to perform fast drilling and blasting operations on a strong rock bed.
