ROAD SWEEPING MACHINE WITH SEVERAL SWEEPING MODES Russian patent published in 2020 - IPC E01H1/02 E01H1/04 E01H1/05 E01H1/08 

FIELD: machine building.

SUBSTANCE: group of inventions relates to versions of a sweeping machine for movement in the direction of movement to remove garbage from the swept surface of the roadway. Sweeping machine comprises at least first and second side brushes mounted on the machine. Each side brush is movable between retracted position and extended position and has motor for rotation of its corresponding side brush in direction of rotation for sweeping at least part of garbage on swept surface into area between first and second side brushes. Machine also comprises the first suction hole on the first side of the machine or next to it and the second suction hole on the second side of the machine or next to it. Each suction hole is connected through a corresponding valve for air flow with bin for garbage. Each airflow valve operates between a substantially open position and a substantially closed position. Machine comprises fan to create air flow passing through bin and at least one of suction holes when valve connected with at least one suction hole is in its essentially open position. Machine is equipped with the main brush for transfer of material having the appropriate engine for rotation. Machine may also comprise first auxiliary brush for material transfer, having corresponding engine for rotation of first auxiliary brush for material movement around axis of rotation in first direction of rotation to move at least a portion of garbage in the gripping direction by the first suction port when the sweeping machine moves in the direction of travel. Machine can also be equipped with second auxiliary brush for movement of material, having corresponding engine for rotation of second auxiliary brush to move material around axis of rotation in second direction of rotation to move at least part of garbage in direction of grip by second suction hole, when sweeping machine moves in direction of movement. At that, main brush for material movement is rotated in selected one of first direction of rotation to move at least part of garbage to first auxiliary brush for material movement and second direction of rotation to move at least part of garbage to second auxiliary brush for material movement.

EFFECT: technical result consists in improvement of efficiency of road surface sweeping.
