JET SUCTION DRAG HEAD Russian patent published in 2008 - IPC E02F3/88 

FIELD: fixed constructions.

SUBSTANCE: drag head comprises a jet pump, force and suction lines, replaceable angle inserts, that allow changing the jet pump tilt angle and are disposed between said lines and jet pump, and quick-release flanged connections disposed between the jet pump and inserts. On the ends of the replaceable angle inserts there are brackets that are articulated to one another to ensure lifting the front end of the jet pump. The articulations are arranged coaxially and directly above the flanged connections.

EFFECT: increasing the jet pump performance in shallow depth earthwork operations; reducing the labour coefficient for its servicing.
