FIELD: hydromechanization facilities.
SUBSTANCE: invention can be used for dredging in water pools, production of nonmetalliferous construction materials such as sand, gravel. Proposed device contains slot-type with hydraulic ripper in which mount of intake has variable height decreasing from middle to edge according to following dependence: hm=hm.ocos arc tg br/l where hm is height of intake mouth at arbitrary distance from middle; hm.o is height of mouth in middle of intake; br is distance from arbitrary point of mouth to middle of intake; l is length of contraction part of intake.
EFFECT: improved suction of ground at edges of intake mouth owing to equalizing suction velocities over width of intake.
