PERCUSSION MACHINE FOR DRILLING HOLES IN THE GROUND Russian patent published in 2022 - IPC E02F5/18 

FIELD: construction.

SUBSTANCE: invention relates to the technology of construction works, namely trenchless laying of underground utilities, and can be used to obtain wells in the soil of a rectilinear trajectory. Percussion machine for drilling wells in soil contains a body with a striker located in it with the possibility of reciprocating motion and an intermediate element installed in the front part of the body. A splitter is installed in the front part of the intermediate element, made in the form of a spring-loaded anvil with the possibility of limited axial movement. A leading tube with at least one hole is installed in the front part of the body. A cavity is formed between the inner surface of the advanced tube and the outer surface of the divider.

EFFECT: increased efficiency of the machine by reducing the probability of deviation of the machine from a rectilinear trajectory, reducing energy costs and increasing the rate of penetration of the well.
