AGGREGATE FOR CLEANING WATERS FROM BOTTOM SEDIMENTS AND EXTRACTION OF MINERALS FROM WATER Russian patent published in 2018 - IPC E02F5/28 E02F3/06 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of hydromechanical cleaning of reservoirs from bottom sediments, and also for the extraction of minerals from under water (bottom ooze, placer gold) and the extraction of bulk materials (sand, gravel). Unit contains a device for transporting bottom sediments anchored on a floating device, consisting of a cylinder connected to the column, to which a filter is attached, which excludes the ingress of large stones into the device, a V-shaped knife fixed to the cylinder from the side opposite to the direction of movement of the unit, and a screw. In this case, the screw is installed in the cylinder and connected to the rod string. Screw is given a rotational motion. And the device for transportation of bottom sediments is fixed on the boat through the mechanism of setting the depth of penetration into the ground, made in the form of a pair of screw-nut. Screw is connected to the drive, which ensures its rotational motion. Filter is made in form of a frame crate.

EFFECT: technical effect: an increase in the flowability of cobble minerals, sufficient for their steady (uniform) lifting by a screw, and punching wet ground all along the route, as well as increase in unit productivity and reduction in energy costs.
