Abstract

This invention relates to hydromechanization and is intended for underwater excavation. The goal is to increase the efficiency of the device by reducing the loss of soil. The device includes a tip 1 with suction nozzles 4, ground erosion nozzles (C) 8 communicated with the collector 5, and a ground distributor. The distributor is made in the form of a hollow triangular prism 6 with soil bearing C7. Ground conveyors C 7 are mounted on the side walls of the prism 6. A prism 6 is installed between the suction inlets 4 and is located apex in the direction of the bottom. The cavity of the prism 6 communicates with the collector 5. Ground erosion With 8 placed at the top of the prism 6. Water from With 8 destroys the soil. With a stream of water from C 7, the soil is forcibly adjusted to the suction ports of the nozzles 4, sucked and removed from the zone of the dredger. 2 Il.

The invention relates to hydrophilisation and is intended for the subsoil development.

The purpose of the invention is to improve the efficiency of the device for estimating the reduction of soil losses.

FIG. 1 shows a soil collecting device, top view; FIG. 2 — VID A in FIG. one.

The earthmoving device of the dredge contains a tip 1 with a screen 2, grounding nozzles 3 and suction nozzles kt as well as a collector 5 of hydraulic ripper and a ground distributor, made in the form of a hollow triangular prism 6 with the apex directed to the bottom side.

The prism 6 is installed in the center of the ek-2 between the suction inlets k. On the lateral surfaces of the prism 6, ground supply nozzles 7 are installed, directed to the suction ports of the C nozzles, and at the top of the prism 6, soil erosion nozzles 8 are mounted, directed along the axis of the intake device towards the bottom and communicated with the collector 5. Prism 6 is bare. with collector 5.

The device works as follows.

At the beginning of the work, the pump r on the rider is turned on and water is supplied through the collector 5 of the hydraulic ripper to the ground supply nozzles 3 located on the screen 2, as well as through the internal cavity of the prism 6 of the ground distributor to the ground supply nozzles 7 and the ground washing 8 nozzles. Then, the soil pickup is lowered to a predetermined development depth, the soil pump is turned on and the dredge is advanced. The soil collecting device comes into contact with the soil mass, by mechanical action of the screen 2, the soil is separated from the mass and, moving towards the soil collecting device, is affected both by the ground feeding nozzles 3 located on the screen 2 and the ground feeding nozzles 7 located on the lateral surfaces of the prism 6 of the soil distributor, the nozzles 3 and 7 force the soil to

5, the suction nozzles are sucked in and removed from the dredger zone. Water flowing out of the soil-emitting nozzles 8 provides loosening of the soil in the center of the soil collecting device and carrying out the flow of loosened soil reflected from the array in the direction of the suction ports of the pipes k.
