The specific embodiment

The structure of small-sized pure sweeping road sweeper such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6.Axle at two pairs of wheels 30,31 is put on the shelf and is being adorned chassis 5, driver's cabin 1, motor 2 and rubbish storage bin 3 that manipulation device is arranged in being installed with on the chassis, motor 2 is connected with wheel by Hydraulic Power Transmission System, the front end on chassis 5 is equipped with the front side sweeps system 4, the middle position of bottom, chassis is being adorned central rolling and brushing system 6, the floor 8 of inclination is equipped with in rubbish storage bin 3 bottoms, and the back basifacial of rubbish storage bin has garbage emission door 9.

Rolling and brushing system of central authorities structure as shown in Figure 3, Figure 4, the front end of the housing 21 of lower openings is connected the bottom, chassis by hinge 23, the rear end of housing is connected with chassis 5 with hinge 20 by lifting hydraulic cylinder 7.The hydraulic motor 10 that links to each other with hydraulic control system is packed on the housing 21, the axle of hydraulic motor 10 is with affixed by an end of the roller brush shaft 11 of bearings in housing 21, the other end of roller brush shaft 11 is installing minor sprocket 13, adorning cylinder rolling and brushing brush 12 on the roller brush shaft 11, minor sprocket 13 is connected with hinge wheel 15 by chain 14, hinge wheel 15 is installed in an end of driving shaft 16 by spline, the driving shaft two ends are installed in a side by bearing to be had on the helical conveyor tube 18 of opening, helical conveyor tube 18 is packed on the housing 21, helical conveyor 17 is installed on the driving shaft 16, the other end of helical conveyor 17 links to each other with carrier pipe 19, the other end of carrier pipe 19 feeds in the rubbish storage bin 3, and deflector 22 and baffle plate 24 are packed in respectively between housing 21 and the helical conveyor tube 18.

Structure such as Fig. 5, shown in Figure 6 of system swept in the front side, the hinged side scanning arm 25 that is installed with of 5 left and right sides front end on the chassis, side scanning arm 25 front ends are installed with side and sweep hydraulic motor 28, side is swept hydraulic motor 28 and is linked to each other with hydraulic control system, the axle that side is swept hydraulic motor 28 is connected with side brush 26, and support cylinder 29 1 ends and the chassis 5 of side scanning arm 25 lower ends are hinged, the other end and side scanning arm 25 lower hinge, connection oil cylinder 27 1 ends and the chassis 5 of side scanning arm 25 inboards are hinged, the other end and side scanning arm 25 hinged inside.

Operating principle is under the operation of the manipulation device of road sweeper in driver's cabin 2, by Hydraulic Power Transmission System road-sweeper is travelled.The front side is swept when side in the system is swept hydraulic motor 28 and rotated under the operation of hydraulic control system and is driven side brush 26 rotation to the inside, and side brush 26 is swept rubbish to road-sweeper central authorities, so that the cleaning of central rolling and brushing system.Hydraulic control system operation support cylinder 29 can make side scanning arm 25 drive side brush 26 liftings, puts down during cleaning, and platform rises during transportation, and hydraulic control system is operatively connected oil cylinder 27 can make side scanning arm 25 drive side brushes 26 swing, so that clean different places.

Hydraulic motor 10 in the rolling and brushing system of central authorities drives roller brush shaft 11 and rotates when rotating under the operation of hydraulic control system, roller brush shaft 11 drives cylinder rolling and brushing brush 12 and rotates by direction as shown, when cylinder rolling and brushing brush 12 rotates rubbish thrown along deflector and baffle plate from the opening part of helical conveyor tube into the helical conveyor tube 18, meanwhile driving minor sprocket 13 rotates, minor sprocket 13 drives hinge wheel 15 by chain 14 and rotates, the helical conveyor 17 that hinge wheel 15 drives on the driving shaft 16 rotates, and the helical conveyor 17 of rotation promotes rubbish and enters rubbish storage bin 3 by carrier pipe 19.The floor 8 of inclination is equipped with in rubbish storage bin 3 bottoms, and there is a garbage emission door 9 at rubbish storage bin 3 rear portions, when rubbish storage bin rubbish 3 is filled, opens garbage emission door 9, and discharge by discharging door 9 on the floor 8 that rubbish tilts in its action of gravity lower edge.Hydraulic control system operation hoist cylinder 7 makes 4 liftings of central rolling and brushing system, puts down during cleaning, mentions during transportation.

Helical conveyor 17 is brushed 12 shared power source hydraulic motors 10 by chain drive and cylinder rolling and brushing, and power is provided convenience, and is simple and compact for structure, and helical conveyor 17 rotating speeds are low, and consumed power is little.Rolling and brushing system of central authorities is the power that utilizes hydraulic motor 10 to rotate, driving cylinder rolling and brushing brush 12 rotates, when cylinder rolling and brushing brush 12 rotates rubbish thrown in the helical conveyor tube 18, helical conveyor 17 promotes rubbish when rotating and enters in the rubbish storage bin 3 by carrier pipe 19.The cleaning of rubbish is to carry out in the housing of a sealing, and the conveying of rubbish is to carry at the carrier pipe 19 of sealing.Therefore, refuse sweeping and course of conveying can not cause the secondary pollution of rubbish.
