Discharge tips 14 , 15 with nozzles 54 are placed in the upper part of the containers 3 and 4 and allow the estimates to be evenly distributed in the tanks of the hopper.

In addition, labyrinth seals 56 are provided at the junction points i of the discharge tips 14, 15 with the pipelines 52, 53. Articulated to the picker casing 1 and the backshell casing 57 of the picker 17 levers 58 and hydraulic cylinders 59. For dumping the unloading of the hopper 2 on the base chassis 1, a lifting mechanism is installed to tilt the bunker, which is designed as hydraulic cylinders pivotally mounted on the base chassis 1 and sliders that interact with the guides mounted on the water tank 28, and for opening and closing the tailgate 17, hydraulic cylinders 60 with hydraulic locks (not shown) are used. The control of all units and mechanisms of the floor-cleaning machine is carried out from the control unit located in the driver's cabin.

Sweeping machine works as follows.

When the machine is moving along the route to the area to be cleaned from the estimate (garbage), the fans 6, 7 and the autonomous engine 36 are turned off, the valves 16 for air passage are open, the tray brushes 10, the pick-up 11 of the estimates are in the transport position.

For cleaning the cost estimates from the surfaces, for example, the carriageway, start the autonomous engine 36 and, through the hydraulic equipment of the machine, turn on hydraulic cylinders 44, 59 of the tray brushes 10 and pick-up 11 estimates for lowering them to the floor, simultaneously include hydraulic motors 45, 48 of the tray brushes and cylindrical brush 47 hydraulic motors1 38, 39 veins

Thil Tori 6 and 7, while the gate valve 9 is installed in the rearmost position, opening fully bore section of the cone-shaped receivers 51 estimates. At the same time, but include a pump for injecting water from the water tank 28 to the nozzles of the Tray brushes Yu and the discharge tips 1, 15 to dedust the air under the machine and in the container 3, the hopper 2. When the blade rotates, the fans 6 and 7 initially create a vacuum In the suction inlets 22, 23 of the fans, and when opening the IM check valves 31, a vacuum occurs in the vacuum chamber 19. Due to the occurrence of vacuum in the chamber 19 of the vacuum in the pneumatic system of the machine, air flows are directed from the pick-up 11 to the estimate through the tanks 3 and 4 filters 8 and 9, the vacuum chamber 19 to the fans 6 and 7, the purified air is released into the atmosphere through additional filters 42 .

Rotating trough brushes 10 form a shaft of the estimate. which due to the movement of the machine enters the pickup 11 estimates. The rotating cylindrical brush 7 throws the estimates into the estimate receiver 51, which is picked up by air - /, by air flows and transported simultaneously in the tank 3 and the hopper 2, where it settles on the bottom 27. In the initial loading period of the hopper 2, the nozzle 5A is in the extreme the rear position, and as the estimate is received and the mass of the mass increases, the nozzles 5 are advanced axially to evenly distribute the estimates in the tanks of the hopper 2.

After cleaning a portion of the carriageway, the car is transferred to a part of the sub-strip lane, for example, s with a high degree of contamination, where similar tricks are used to clean the sub-strip strip of the road. After filling the containers 3 and k of the hopper 2, the machine’s direction of movement is reversed by approximately 60-70% and the tray band is cleaned, the hydraulic motor 39 of the fan 7 is turned off, the valve 16 is closed to allow air to pass through, placed on the right side the hopper 2, by means of the hydraulic cylinder 33, is shut down described
