Description

one

The invention relates to the hydromechanization of earthworks and is intended for the development of soils in underwater fences.

A primer-collecting device in the dredger is known, which includes a suction pipe, a suction tip and a hydraulic vibrating baking powder, enclosing the suction tip 1,

The drawbacks of such a device are the inefficient use of vibration and pressure jets, and the need to supply pressure water to the nozzles from the water pump from the dredger deck.

A primer-collecting device of the dredge is known, including a suction pipe, a suction tip, and an annular vibration screen with teeth 12.

However, this soil-collecting device has little effectiveness in the development of soil due to only the vibration effect on the soil that is not washed out by the erosion flow.

The purpose of the invention is to increase the efficiency of soil development.

This goal is achieved by the fact that the dredger of the dredger is equipped with a casing connected to the disintegrant, while the enclosure and the disintegrant are attached to the suction tip by means of a ball and are rotatable relative to the suction tip.

The vibrator is made in the form of a ground pump.

20, a casing 7 connected to the plate 3 by a connection 8. The plate 3 and the casing 7 are suspended from the suction tip 2 at the hinge nodes U. The cavity between the plate 3 and the casing 7 is equipped with a suction pump 10 with an electric motor 11, suction 12 and pressure 13 branch pipes. The suction foot of cuttings 12 is located above the window 4. The discharge nozzle 13 is equipped with a nozzle 14 with a mouth facing the ground 15. The nozzles 14 are located above the window 5. The device also contains a cable 16, a lifting cable 17, an electric cable 18 and a zone 19 scouring and weighing the soil. The suction pipe 1 is adopted in the form of a flexible hose to damp the oscillations in the event that they are transferred by a hydrovibration baking powder to the suction tip. The device works as follows. The ground conveyor is fed to the ground. The suction tip 2 with its mouth touches the ground 15. By the flow of water, flowing to the tip 2, the soil is eroded and sucked into the tip. However, the intensity of soil excavation by erosion is not great; The ground pump 10 is put into operation, which is above the ground surface 15 Water from the surrounding water area through the window 4 enters the suction nozzle 12 of the ground pump 10 and is discharged under pressure from the nozzle 14. The water from the nozzle 14 is washed down by the soil 15 and weighed. An erosion and weighing area is formed. From the soil-grinding and weighing zone 19, the slurry is sucked into the suction tip 2, and from the tip enters the suction pipe 1. As the size of the zone 19 increases, the suction tip 2 is sunk into it until the teeth 6 of the plate 3 sink into the soil 15. When The operation of the ground pump 10 causes the pump to vibrate, which is transmitted to the slab 3 with the teeth 6. The teeth 6 produce the vibratory loosening of the soil 15. The particles of the broken soil are carried away by the flow of water through the window 4 to the ground pump 10 and through nozzles 14 are thrown out n aporn jet slurry. A slurry jet having a higher density than a water jet produces an effective erosion and weighing of soil in zone 19. The 4 slurry from zone 19 is ready to be sucked in by a tip 2. A switching device with a connecting cable 16 is switched on. The device moves to the left (see drawing), loosened the ground by vibration, erosion of the concentrated pressure jet of the slurry. Ready slurry from suction and suction zone 19 is sucked by the tip 2. All this leads to an increase in the efficiency of excavation. The cable can be papillonated in any direction using the cable 16. The screen with the plate 3 and the casing 7 is rotated in the hinge assemblies 9 so that the screen is always in front of the suction nozzle. If it is necessary to move the device in the face, it is lifted with the help of a lifting cable 17. The electric motor 11 is powered by an electric cable 13. The introduction of this soil collecting device makes it possible to increase the efficiency of the development of the soil. The disintegrant is always on the side of the forehead, i.e. loosens the soil from the papilioning side, thus achieving the full efficiency of vibrational and hydraulic soil loosening. As a unit for receiving pressurized water, a ground pump was taken down to the bottom of the bottom, so that it was not necessary to supply pressurized water from the dredger deck. This saves energy on education and supply of pressure water to the nozzle. The negative effect of the ground pump operation — the inevitably arising and concomitant vibration during its operation — gets a positive use for loosening the soil. Erosion and soil extraction in the bottomhole is carried out with a ny jet of slurry, which has a greater energy reserve than the water jet, which leads to an increase in the intensity of the erosion and weighing of the soil. The rotation of the baking powder provides high mobility gruzitozabornogo device. Claim 1. Intake device of a dredger, including a pipe with
