DEVICE FOR GROUND WELLING Russian patent published in 2018 - IPC E02F5/18 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely to devices intended for trenchless laying of pipelines, and can find application for the device of the latent transitions at construction of pipelines, underground cable communication lines and electric transmission. Device comprises a screw conveyor that is pivotally connected without the possibility of mutual rotation with a tapered working tip, inside which a vibrator of circular oscillations is mounted. Vibrator of the circular oscillations is made in the form of an unbalance mounted on the rotation supports in the conical working tip and is connected to a motor by a flexible shaft which is mounted in an additional housing connected to the working tip by a flexible coupling. In the unbalance, a drive shaft is mounted on the rotation supports, which is connected to the unbalance by means of overrunning clutches, and in the forward part in the direction of penetration the part is connected to the conical working tip via an electromagnetic clutch and a reducer.

EFFECT: increase the effectiveness of the device in soils with heterogeneous physical and mechanical properties.
