Description

The invention relates to the field of amelioration and can be used when flushing closed horizontal drainage.

A working tool for flushing drains is known, including a hose flushing mechanism and a flushing head made in the form of a Segner wheel and equipped with cutting elements | 1J

A disadvantage of this device is low. The efficiency of using the energy of the Veda when cutting roots in drains with simultaneous translational movement of the head.

Known working body for the flushing of drains, which is the case of a movable horizontal cylinder, on which are installed the expanding stops, the hollow rod, the hydrodistributing mezzanism, and the washing head Cz 1.

The disadvantage of this working body is low efficiency when cleaning drains containing plant roots.

The purpose of the invention is to improve its effectiveness. efficiency of the work & n head.

This goal is achieved by the fact that the working body is small. for draining drains fitted radially on

a hollow stem is placed between the washing head and the horizontal cylinder by spacer hydraulic cylinders, the working cavities of which are hydraulically connected to the idle cavity of the horizontal cylinder.

FIG. 1 shows a side view of the device, in partial section; FIG. 2 shows section A-A in FIG. one.

The working body of the drain cleaning machine consists of a body of a movable horizontal hydraulic cylinder 1, a hollow rod 2 with a piston 3, and a rotating wash head 4. Inside the hydraulic cylinder 1 there are two plates 5, rigidly connected to each other by means of rods 6, which are located in through holes 7 piston 3, the plates are spring-loaded relatively

20 of the hydraulic cylinder body with springs 8. The movable horizontal hydraulic cylinder has a cavity of working stroke 9 and an idling cavity 10. On the outer surface of the hydraulic cylinder case of the cylinder 1, there are expandable stops 11, made in the form of a spring-loaded hinged pargiplogram.

On the outer surface of the hollow shaft 3 rigidly and radially ustanavlvv.

30 are spacer hydraulic cylinders 12, consisting of a sleeve 13, a piston 14 with a rod and supporting elements, and springs 15.

In the body of the hollow rod, inlet holes 16, outlet channels 17 and channels 18 are connected, connecting the working cavities of the expansion cylinders 12 to the idling cavity 10 of the movable horizontal hydraulic cylinder.

The rotary washing head 4, provided with cutting elements 19, front openings 20 and driving nozzles 21, is mounted on the front end of the hollow stem 2, which is connected to the supply hose of the washer.

The proposed working body of the machine for cleaning drains works as follows.

Water under the pressure created by the injection pump of the draining machine is supplied to the internal cavity of the rod 2 through the water-supply hose, where the flow is separated. Most of the water enters the rotating washer head 4, from where it flows out of the front holes 20 and the drive nozzles 21 into the cavity with great energy. drainage. At the same time, water streams flowing out of the front holes erode soil sediments, and water streams flowing out of the drive nozzles 21 impart a careful movement to the head, as well as clean the walls of the drainage pipes from sediment residues not smeared by the front streams. The roots of plants encountered on the path of the working organ are cut off by cutting elements 19.

A smaller part of the water through the inlet holes 16 enters the cavity of the working stroke 9 and the cavity of idling 10 horizontal movable hydraulic cylinder 1.

at the moment of operation, when the piston 3 is in the extreme left position (as shown in the drawing), the left plate 5 is pressed by the force of the left spring 8 to the end surface, and the right is pressed out from the end surface by rods 6. Water entering the cavity of the working stroke 9 of the hydraulic cylinder, presses on the inner surfaces of the cylinder and the piston, but since the cylinder is held in place by the expanding stops 11, the piston 3 with the hollow rod 2 and the water supply sleeve receives forward movement.

Thus, the working stroke of the working body is carried out. During the working stroke, water enters through the inlet 16 into the idle cavity 10 of the movable horizontal hydraulic cylinder 1, through the through holes 7 of the piston 3 and through the vnj-vHjjia and canals 18 expire into the cavity

the drainage to be cleaned, and the right TG spring is compressed. At the same time, the pistons with the rods and supporting elements of the spacer cylinders 12 under the action of the springs 15 are in the lowest position and do not prevent the working member from moving forward. The stroke continues until the force of the right spring 8 exceeds the force from. water pressure in the working cavity

9 hydraulic cylinders 1. At this moment, the right plate 5 is pressed to the end surface of the piston 3 and the left plate is pressed from the piston by means of rods 6. At the same time, the water supplied under pressure through the inlet 16 to the idling cavity 10 of the hydraulic cylinder 1 is fed through channels 18 into the working spaces of the spacer cylinders 12, pressing the piston 14 with the rod and supporting elements against the walls of the pipes being cleaned, simultaneously compressing the spring 15, and also presses against the inner surfaces of the cylinder and the piston, but since the piston 3 and when the forces of friction against the support elements of the piston 14 of the spacer cylinders 12 are pressed against the walls of the pipes being cleaned, the horizontal cylinder 1 with the expanding stops 11 receives the forward movement. Thus (idle speed of the working gas is idle. coming through the hole 16 into the cavity of the working stroke 9 of the hydraulic cylinder 1, through the through holes 7 of the piston 3

and the exhaust channels 17 expire into the cavity of the drain to be cleaned, while the left spring B is compressed. The idling of the tool is continued until the compression force of the left spring 8 exceeds the force from the water pressure in the idling cavity.

10 hydraulic cylinders 1. At the same time, the left plate 5 is pressed against the end surface of the squeeze 3, and the right is pressed. This ends one cycle of operation and begins the next cycle of operation of the working body, analogously to the one described above, and so on.

To start the working body at the beginning of work or during the cleaning process, after the water supply is cut off, the hollow rod 2 with the piston 3 with the water supply sleeve is pulled back until the left spring 8 is compressed, after which the discharge valve and the washing machine are started as described above.

The working body of the drain cleaning machine will significantly reduce the cost of cleaning work on closed drainage systems.

plugged with soil deposits with vegetation roots.
