Abstract

The invention relates to equipment for dredging and m. Used for underwater mining of various categories. The goal is to increase the efficiency of the operation of the dredger through more complete soil extraction. The dredger includes a floating hull with a power plant and a submersible device. The following is made in the form of a scoop 8 mounted on the frame 7 of the underwater belt conveyor (T) 9, and a pressure T 10. The T 10 is made in the form of an endless belt with a mechanism for changing the distance between T 10 and T 9 and the drive 11. During operation The dredger is connected in series with the above-water T 4, underwater T 9 and pressure T 10. A distance approximately equal to the thickness of the soil layer to be cut is controlled between T 9 and T 10. Winches 3 moving dredger yes are included. With the help of the ram-lifting winch 6, the frame 7 is lowered until the scoop 8 reaches the desired depth. The soil selected in the well 5 is transported to the dump or to the barge by any known method. 2 Il. g

The invention relates to equipment for dredging and can be used for underwater mining of soils of various categories.

The purpose of the invention is a higher efficiency of the operation of the dredger and due to a more complete extraction of the ground level.

Female scoop the desired depth. Symmetrically located on the hull of the dredger and the frame is at the same time in a raised position (non-working position).

Upon reaching the end of the trench, these mechanisms are moved to the inoperative position: frame 7, using the frame in FIG. 1 shows a part of the replacement — the lifting winch 6 is raised, the length, longitudinal section; in fig. 2 dredger, top view

The dredger contains a floating hull 1, on; which installed power plant 2, winch 3, displacement., surface conveyor 4, soil well 5, frame-raising winch 6, frame 7, pivotally connected to a floating corulus, ground-intake device, filled with scoop 8 mounted on an underwater frame hsentochny conveyor 9 and clamping conveyor -10, made in the form of an endless belt with a mechanism for changing the distance M12ZH-to them and drive 11 o & For the purpose of eliminating idling on the floating body (Fig. 2), symmetrically surface conveyors, ram-lifting winches, frames with -surfaced and near conveyors and (mechanisms for changing the distance of their drives, and a soil sampling shovel

The operation of the dredger is carried out by the trench method. The dredger row is installed at the work site, the crust is brought in, then the surface conveyor 4 is driven sequentially from energy source 2. The underwater conveyor 9 of the pressure conveyor 10, the mechanism for changing the distance between the conveyors is adjusted between them, which is approximately equal to the thickness cut layer of soil. Then, in the winch of the winch, 3 moves the dredger. With the help of the frame-lifting winch 6 7 lowering up to 15

the water of the conveyors is turned off, and B1 is sequentially connected with mechanisms symmetrically arranged.

The soil selected in the well is transported to a dump or barge site by any known method.

The speeds of the upper branch of the underwater conveyor in the lower branch of the clamping conveyor are equal to the speed of movement of the dredger.
