Description

one

This invention relates to reclamation machines designated for cleaning drainage pipes and other tubular communications from silting products.

It is known ycTpoficTBO for the washing of water with drainage pipes, which includes a base tube, on which there is a working head with an outlet for water and an invisible back 1.

A well-known thromschanpic working body of a drainage cleaning machine, including a water-supply hose, napl anle uni sae, wash, go; way; t to the market and gnrodpntatel, with an integral shaft | 2.

The lack of a working oprarfa is a great deal of coolness on the ripper.

11, ate) isobrechioi - non-whitish - IxlieKTH; by increasing the amount of K) of the southerner and the ripper without increasing water consumption.

This is achieved by the fact that the impeller head with a ripper is rigidly fixed by an axle to the hydraulic motor shaft, which is made in the form of a cylinder divided into two chambers by a rotary valve with a spool, the central cavity of which is connected with a water supply hose and the cavities adjacent to it serve for alternately connecting The atmosphere and the corresponding cameras pilgsdra.

Cha FIG. 1 schematic shows hydromechanical working body of the cleaning machine, a hydrodynamic section; Ia fng. 2 is a section A-L in FIG. one.

The hydraulic mechanic work unit of the preparatory tank consists of a water supplying sleeve 1, a guide sled 2, a hydraulic motor 3 and a flushing head with a ripper 4. The hydraulic motor includes a housing 5, an ileal shaft 6, a rotary blade 7 and a zooptic 8, forming a central shaft in the housing 9, adjacent to Pei polopi 10 and 1, and terminal poloetn 12 and 13. In the housing 3, holes 14-17 are made, connected to u. 1, not cavities 10-13 with the atmosphere. In the housing, one can also drop 8, connecting n, 01 to the trap cavity 9: the internal cavity of the engine, holes 19 and 20, connecting the left and right chambers 2 and 22 of the hydraulic motor with cavity 10 and the spool, and channels 23 and 24, connecting 12 and 13 e holes 25 and 26, made in the hollow shaft of the hydraulic actuator.

The washing head is fixed on the hollow shaft and provided with holes 27-29 and cutters 30.

Hydromechanical working body works as follows.

The water from the pump from the sump washing pump 1 to the water supplying sleeve 1 simultaneously enters the hollow shaft 6 and the channel 18 into the central cavity 9. Most of the water that has flowed out from the openings 27-29 of the flushing head, erodes the soil deposits inside the pipes being cleaned and informs the working member t gu.

Remaining part of the water at the extreme right position of the spool 8 (see Fig.) Through the opening 20 enters the right-hand engine chamber 22 of the hydraulic motor and rotates the rotary lion to the left together with the hollow shaft 6. At this moment the left-hand camera 21 through the hole 19, the adjacent cavity 10 and hole 15 is connected to the atmosphere. The left rotation of the hollow shaft continues until the hole 26 of the hollow shaft coincides with channel 24. At the moment of coincidence of the hole and channel, the pressurized water enters the right graft cavity 13 and moves the spool 8 to the leftmost position, since the left end cavity 12 at this time, it is disconnected from the panpurous flow of water previously entering the pei through the opening 25 and the channel 23, and connected by the opening 14 to the atmosphere.

Moving to the extreme left position, the spool 8 disconnects the opening 20 with the channel 18 and connects it through the opening 19 to the atmosphere. At the same time, through the opening 19, the left chamber 21 of the hydraulic actuator is connected to the pressure head of the water, resulting in a rotary blade 7 together with the hollow shaft 6, it pivots to the right, since the hydraulic engine chamber 22 is right through the opening 20, the adjacent cavity 11 and the opening 16 is connected to the atmosphere.

The right rotation of the zero shaft continues until the hole 25 coincides with the channel 23. At this moment the water enters the left end layer 12 under pressure and moves the spool 8 to the edge of the right position, the cycle of operation of the hydraulic igniter is repeated.

With the right-hand left rotation of the hollow shaft, the sediments are loosened by the cutters 30. Before cleaning the drill, before turning on the pump, flush the head and place it in any extreme position in which the end cavities of the end cavities are connected to the hole of the hollow shaft.

Formula and 3 about b and e and

The hydromechanical working body of the drainage cleaning machine, which includes a water-supply sleeve, guide rails, a wash head with a ripper and a hydraulic motor with a hollow shaft, characterized in that, in order to increase efficiency by

increasing the torque without increasing the water flow; flushing the head with the ripper is rigidly fixed on the hollow shaft of the hydraulic motor, which is made in the form of a cylinder divided into two chambers with a rotary blade with a spool, the central cavity of which is combined with a water supply and go to a sleeve, and for poocher; and a single compound with the atmosphere and the corresponding chambers of the cilidra.
