FIELD OF THE INVENTION The invention relates to agricultural and municipal engineering, in particular to urban sanitation machines.

The purpose of the invention is to increase labor productivity while reducing labor costs.

FIG. 1 shows a machine for cleaning drainage wells, a general view of FIG. 2 is a section A-A in FIG. 1 (filter); in fig. 3 shows a section BB in FIG. 1 (kinematic diagram of the operation of the air nozzle)} in FIG. 4 shows a kinematic diagram of the operation of pressure-injection pipelines.

The machine includes a trailed chassis 1 on a pneumatic passage, on which a tank 2 is installed, a filter 3 installed in the tank, a vacuum-pressure system 4, a well cover lid 5. The vacuum-injection system is equipped with a nozzle 6, and the pressure-discharge pipes 7 are built into the bottom of the tank. The machine is equipped with a suction sleeve 8. The nozzle 6 is placed in a drainage well 9. Capacity 10 is connected through a four-way valve 11 with containers 12 and 13. The well 9 is equipped with pipelines 14. The machine is equipped with pipes 15, 16 and 17 with valves 18. The nozzle 6 is vacuum The injection system is placed at 19. Filter 3 consists of a cylindrical body 20 with slit-like openings 21, support fittings 22 and 23, and a finely meshed grid 24.

The machine works in the following way.

The machine arrives at the reservoir with pure water, turns on the vacuum system to create a vacuum in the tank 2 and collect 0.4-0.5 m of clean water through the suction hose 8. Then the car drives up to the drainage well 9, the lifting mechanism 5 removes the cover of the well 9 and drains the previously collected clean water with one thing: temporarily switching the four-way valve 11 to the Discharge position. Close the valve 18 on the discharge pipe 15 and open it on the discharge pipe 17, which is connected by a rubber hose through the drum 19 with the nozzle 6. Then compressed air is fed into the nozzle 6, after which it is installed in the drainage well 9 under the water level and solid compacted particles in suspension. Then, the four-way valve 11 is switched to the Suction position and the prepared liquid mass is drawn into the tank 2. until the well 9 is completely cleaned. After the pulp intake is completed, the machine drives to the next well. In order to wet the solid particles of the soil with water, a tap 18 is opened,

associated with a filter 3 consisting of a cylindrical body 20 with slit-like openings 21, outside of which supporting fittings 22 and 23 are fixed along the length and perimeter,

a fine mesh 24, through which the pulp is cleaned for further work.

At full filling of the four-way tank 11 crane switch

again in the Injection position, they close the regulator on the pipelines 16 and 17 and open it on the pipeline 15, which is connected to the pressure-injection pipelines 7. With

compressed air, the settled particles are brought into suspension with simultaneous increase in pressure in the tank 2. Then the drain hole is opened and the pulp is released,

empty the carrying tank for the next cycle.

The machine allows to fully mechanize the cleaning of drainage wells, significantly increase labor productivity by 4-5 times and reduce the cost of work performed by 2-3 times.
