DESCRIPTION

(16) A preferred embodiment of the equipment (vehicle) comprises a fixed chassis (1) having traction wheels (2) and driven wheels (3) with respective mudguards (4 and 5), cabin (58) with rear-view mirrors (6) access doors to the interior (100) of the cabin (7), rear bumper (8), headlights (9), lower rear (10) and upper (11) traffic lights, battery (23), front windows (26) and rear windows (27), being equipped with a combustion or electric motor (12) associated with a hydraulic pump (13), having hydraulic motors (14) connected to the front traction wheels (2) and responsible for moving the vehicle and a hydraulic motor (28) for the exhaust fan (29), wherein the hydraulic fluid is stored in the reservoir (24) adjacent the rear bumper (8) and is cooled by the radiator (25).

(17) The vehicle has a fairing assembly (15) containing the access doors (16) to the mechanical assembly, a door (17) of the dirt chamber (18), provided with an inspection sight glass (19) for viewing the chamber, and the debris collection box (20) is arranged on this chamber (18).

(18) The vehicle is maneuvered by steering (21) which drives the hydraulic cylinder (22) arranged close to the axis of the rear wheel (3).

(19) On the front of the vehicle there are a pair of rotating brooms (30) which are integral with the hinged front chassis (31), provided with a protective fairing assembly (32), and such chassis (31) can be in the extended position (33) or the collected position (34) due to a piston (35) actuated from the cabin (58).

(20) Behind the hinged front chassis (31) there is a rod (36) which supports a hinged bar (37, 38 and 39) by means of pistons (40, 41 and 42), responsible for moving a second assembly of brooms (43), in which this assembly of broom (43) is driven by motors (59 and 60) and can move at a 180° angle in front of the front brooms (30).

(21) The front brooms pull downwardly and direct the debris into the pick-up (44), through the front opening (102), provided with a bristle edge forming a brush 45 with a front aperture, where this pick-up (44) has a hydraulic cylinder (46) to move it upwardly and downwardly so that the debris is sucked by means of piping (47), collide with a baffle (48) and are conveyed to the dirt chamber (18) to the debris collection box (20). The suctioning of the debris is achieved by means of the exhaust fan (29), wherein within the dirt chamber (18) there is a filtering system composed of a pre-filter (49) and a filter (50), equipped with cleaning filters (53) with cleaning tube (54), wherein the clean air passes into the clean suction chamber (51) and is demanded into the atmosphere by means of a clean air outlet duct (52).

(22) A manual suction pickup (55) is disposed on the side of the vehicle, having a driving hose (56) and a manual directional valve (57) to suck hard-to-reach debris and drive them into the dirt chamber (18).

(23) FIGS. 10 and 11 show, respectively, the airflow to the dirty chamber (18) and the clean air flow from the clean suction chamber (51) to the outlet (52).
