Description

A kind of electric ground sweeper with independent rear wheel bearing arrangement

Technical field

This utility model is related to new forms of energy sanitation equipment field, more particularly to a kind of electricity with independent rear wheel bearing arrangement Dynamic floor sweeper.

Background technology

At present, common on the market vacuum draw type floor sweeper typically with for the wheel along ground run and At least one be used for clean ground pivotable drive cleaning brush and vacuum waste case.Can by means of this floor sweeper To clean ground, such as street, footpath or parking lot etc..At least one cleaning brush of floor sweeper acts on to be cleaned Ground on and cleaning material is directed to into component suction nozzle, cleaning material is sucked through connected pipeline fortune by component suction nozzle It is sent in vacuum waste case.For this purpose, vacuum waste case is loaded with negative pressure by pumping equipment, so as to constitute from component suction nozzle to vacuum Refuse bin and the aspiration flow from vacuum waste case to pumping equipment.Scavenging machine is configured to self-propelling, such as shape in vehicle Formula.

Wherein, as the scavenging machine of existing vehicle type typically adopts Integral frame structure, vacuum waste case arrange In the region at the rear portion of vehicle frame, and vehicle can have driver cabin in region above.By sweep device, suction nozzle group Part is arranged on before the travel direction of vehicle frame, therefore the vehicle frame that larger and bearing capacity must be adopted stronger, so just cause this Plant unitized frame to go out to turn now to inconvenience, walking cleaning is dumb, and unitized frame road pavement situation adaptibility to response is poor, cause to clean It is undesirable that performance is swept in the suction of machine.Overall bridge hangs simultaneously vehicle or the vehicle of independent crossbeam, as overall bridge hangs or independent Crossbeam can all occupy a large amount of locus, occupy the placement location of refuse collector so that refuse collector is had to Up move, also cause using inconvenience then.

The content of the invention

The purpose of this utility model is to provide a kind of electric ground sweeper with independent rear wheel bearing arrangement.

In order to realize the purpose of this utility model, this utility model provides a kind of electric ground sweeper, wherein, including front Vehicle frame, Rear frame, bearing arrangement and refuse collector, are provided with driving front-wheel, driver's cabin and sweep device, drive in front frame Sail room to be arranged on above driving front-wheel, sweep device is arranged on the front for driving front-wheel, and the both sides of Rear frame are provided with bracing frame With driven rear wheel component, a driven rear wheel component is arranged on a bracing frame, and driven rear wheel component includes tire, brake dress Put and rear-wheel bearing component, tire is connected with brake gear, and rear-wheel bearing component is connected between tire and Rear frame, front frame It is hinged by bearing arrangement with Rear frame, front frame and Rear frame can be rotated in horizontal plane independently of each other, refuse collector It is fixedly mounted between bracing frame.

Further scheme is that rear-wheel bearing component includes axle sleeve and axle, and axle sleeve is fixedly connected with bracing frame, axle with wheel Tire connects.

Further scheme is that steady rest is fixedly connected between bracing frame.

From such scheme, by independent rear wheel bearing, it is that refuse collector concedes a large amount of placement spaces, not only may be used To increase the folding and unfolding space of refuse collector, simultaneously because refuse collector can reduce whole machine closer to ground Center of gravity, operation stability are higher, it is possible to significantly facilitating user operation use.

Further scheme is that electric ground sweeper also includes transfer, and transfer includes setting up separately in bearing The hydraulically extensible bar of device both sides, hydraulically extensible bar are connected between front frame and Rear frame.

Therefore, adjusted by active of the transfer to front/rear frame position so that the operation of scavenging machine is turned to more For controllable.

Further scheme is that electric ground sweeper also includes attachment means, the first end and bearing of attachment means Device is hinged, and the second end and the front frame of attachment means are hinged, and attachment means and front frame can turn in horizontal plane around bearing arrangement Dynamic, front frame is rotated in vertical plane relative to attachment means.

Further scheme is that the second end of attachment means is provided with groove, and the connecting portion of front frame is arranged on groove It is interior, rolling bearing is provided with connecting portion, attachment means also include the fixing axle through groove and rolling bearing.

Further scheme is that attachment means also include reset assembly, and reset assembly includes being fixedly connected with front frame Fixture and the flexure strip through fixture, fixture through groove diapire, the two ends of flexure strip are connected to the bottom of groove Wall, the diapire of groove are located between flexure strip and front frame.

Therefore, arranged by the rotation of bearing arrangement and attachment means so that front/rear frame is in the different road conditions of reply When can absorb outside the impact of multi-angle, can also reduce operating noise, and the operation attitude that can reset in time is conducive to more entering One step improves the operation stability of scavenging machine.
