The invention relates to the mechanization of land reclamation works, in particular for cleaning from sediments of channels of small width, their beds, under bridges and in other hard-to-reach places, where this kind of work is currently performed manually by riverbed mounts.

The purpose of the invention is to enhance functionality and increase productivity.

FIG. 1 shows a device for cleaning channels; in fig. 2 - the same, general scheme, side view.

The device for cleaning canals in hard-to-reach places consists of arms 1 and 2 fixed on solovki 3 and 4, feeding 5 and feeding 6 pipelines. Inside the arms 1 and 2, levers 7 and 8 are mounted, connected to valves 9 and 10 for controlling the water supply. The heads 3 and 4 of the supply 5 and supply 6 pipelines are interconnected by a pipeline 11, to which the supply 12 is adjusted.

The pipelines 5 and 6 are mounted on the base 13 of the upper cone 14 so that the supply pipe 5 supplies water to the reservoir A formed by the base 13 and the side surfaces of the upper cone 14, and the supply pipe 6 feeds the water to the reservoir B formed. mi of the upper 14 and lower 15 cones connected by a cylindrical shell 16.

Hydraulic rippers 17 are installed on the side surface of the lower cone 15 with scour nozzles 18. On the base 13 of the upper cone 14 a pulp outlet 19 is installed, on the lower end of which a diffuser 20 is mounted, forming a hydraulic outlet with a constricting nozzle 21 under pressure scouring the pumps in the channel, and forms a pulp, which enters the pulp discharge 22. 1 s, n, f-ly, 2 sludge.

The air gap C for entering water from reservoir A to pulp outlet 22 creates a vacuum in pulp outlet 22, by means of which pulp is lifted out of the channels. To regulate the size of the gap, the pulpo is made movable in the direction of the vertical axis by means of, for example, a threaded joint.

A flexible hose 23 is connected to the upper pulp outlet 22 for pulp removal from the channels.

The supply 12 is connected by a flexible hose 24 to the hydraulic circuit 25. Thus, I supply pipe 5, reservoir A, pulp drain 19 with diffuser 20 and pulp discharge 22 form a hydraulic elevator

The device for cleaning the channels works as follows.

The device is lowered, for example, into the channel under the bridge and installed vertically. They turn on the hydraulic unit 25 and the water through the flexible hose 24, the inlet 12 and the pipeline 11 enters the heads 3 and 4. When you press the handles. The 1 and 2 levers 7 and 8 lift the valves 9 and 10 and the water through the pipes 5 and 6 is supplied to the tanks A and 5, filling them. .

. Then, water from reservoir A under pressure through the gap C is fed into diffuser 20, creates discharge and pulp from the channel through the pulp outlet 22 nctCTyneT into the pulp outlet 19 and further along the flexible hose 23 is carried to the berm of the channel.

At the same time, water flows through the supply line 6 to the & and through hydrofetters 17 with eroding nozzles 18, it expires under pressure, clearing the sediment in the channel and enriching the water in the channel with pulp that enters the pulp outlet 22.

If necessary, the hydraulic elevator and hydraulic rippers can work separately, for example, in the case when the deposits in the channel are loose. When pressing the handle 1, water enters the reservoir. A and A through the gap C enters the diffuser 20, creates a discharge in it, by means of which loose sediments are sucked together with the water in the channel, enters the pulp outlets 22 and 19, then through the flexible hose 23 - beyond the channel. Depending on the physical and mechanical properties of the sediment, the clearance C can be increased or decreased, thus changing the pumping capacity of the pulp. To do this, turning the pulp outlet 22 in the threaded connection, achieve the required performance.

For example, the channel passes in peats. In this case, the channels of the channel are silted up with particles of peat buza, the mass of which is 1.3-1.7 t / m

To clean this kind of channel, it is necessary to reduce the gap. With the pulp outlet 22 turned clockwise. The outflowing water through the gap from tank A must be mixed in a ratio of 1: 3 with the suction pulp. The ratio of the flow rate of water from a hydraulic tank 25 is checked.

When cleaning the channels passing in mineral soils, the beds are silted with heavy particles.

sand or clay. In this case, the slurry should be less consistency. Therefore, clearance C is increased to allow a large amount of water to pass from reservoir A.

Typically, the gap is increased to mix the incoming pulp from the channel in a 1: 2 ratio. The method of regulation is similar to that described.
