HORIZONTAL DRILLING MACHINE Russian patent published in 2019 - IPC E02F5/18 E21B21/00 

FIELD: technological processes.

SUBSTANCE: invention relates to the technology of horizontal drilling with flushing for trenchless pipe laying in cramped conditions under roads and other engineering structures. Horizontal drilling rig includes a guide device, an axial feed device, a drill connected to a guide rod. Guide tube is made with stops. Drill is made with a central through hole. Axial feeder is made in the form of axial guides mounted on the swivel. Swivel is made with a hole on the side for supplying washing fluid from a pump into it, through which water is supplied with a pressure to the drill through tubular drill rods. Installation contains a collection for receiving drilling fines and a reservoir for flushing fluid, made in the form of a single container with a dividing partition with a grid for the separation of fines and dirty water. At the same time, a single container has a bottom opening for cleaning from trifles after drilling and an opening for draining dirty water, a guide device made in the form of removable tubular guides, on which the electric drill with a reducer and a reverse for ensuring rotational movement of the drill rod and the drill, the removable platform executed in the form of a corrugated sheet is fixed.

EFFECT: reduced installation dimensions, simplified design and increased reliability.
