Of course, the above-mentioned embodiment is only a preferred embodiment of the present invention, and in specific applications, more variations may be provided, for example, a single-drive mode may be adopted for dumping the garbage can, and under the linkage control of the rolling brush and the fan, the fan may also rotate simultaneously when the rolling brush is opened in the default state, the opening and closing of the fan may be controlled by controlling the second M-type two-position four-way reversing valve, the rolling brush rotating hydraulic motor and the blade rotating hydraulic motor may also be connected in series, which may also realize linkage starting, and the garbage can may adopt an integral type garbage can besides a combination mode of the fixed body and the separation box body. And to connecting plate quantity arrangement, can allocate according to the actual product, in addition, adopt the centrifugal impeller mode to carry out the negative pressure suction to fan 33, can adopt axial compressor blade to carry out the negative pressure suction certainly, also can produce the negative pressure effect equally. In addition, the fan driving device 331, the lifting driving device 261 and the rolling brush rotating hydraulic motor 232 are all driven hydraulically, but in this embodiment, the driving devices may be driven electrically or pneumatically.

From top to bottom, connect between round brush box and frame through the connecting plate, utilize lift drive assembly drive round brush box lift removal to realize packing up and putting down of round brush subassembly, can rise when not needing the brush and accelerate the walking speed of street sweeper, then be less ground clearance between round brush box and the ground when putting down, the round brush rotates the rubbish or dust that cleans and can follow round brush export and rubbish entry and get into to the dustbin, thereby effectively improves clean effect. But through height adjustment's round brush, not only can act on the contact degree on ground to the regulation round brush, and can suitably descend the round brush height after the round brush wearing and tearing to improve the life of round brush. Utilize preceding baffle, left bounding wall, right bounding wall and back bounding wall to the surrounding of round brush entry, baffle and bounding wall can adopt softer material relatively in practical application, can effectively reduce ground clearance, when the negative pressure produces the device and produces the suction negative pressure to the round brush box, can improve the suction effect to the soft transmission of cooperation chain, when round brush box lift movement, do not influence the transmission structure of preceding baffle.

Moreover, separate into the rubbish entry through the baffle and go up entry and lower entry to and utilize the intercommunication of leak, and the cross section that the entry was gone up in the cooperation is less than the cross section of entry down, thereby the suction that lies in last entry is greater than the suction of entry down, and the round brush subassembly is when sweeping dust or rubbish simultaneously, heavier rubbish then gets into the lower entry that lies in the downside, and lighter dust then gets into last entry through great suction, thereby utilizes the shunting suction to improve clean efficiency. By arranging the funnel-shaped partition plate, the garbage in the garbage can is prevented from being sucked upwards. The front inclined plate separates the garbage inlet, and the arched leak is arranged behind the rear inclined plate, so that the air channel interference on the upper inlet and the lower inlet is reduced, and the suction efficiency is improved.

And, the free end through being located the guide strip that leans on the inner contacts with the first end of filter core earlier, and the free end of guide strip is located the position that leans on down and can catch first end better, and guide section guide along with the guide strip, thereby the support inner ring on the first end of filter core is installed locating ring platform department, the fixed of the second end of end cover to the filter core of deuterogamying, and the lid closes the installing port, guarantee the relative seal of suction box, moreover, stiff end through the guide strip is connected with the internal perisporium of locating ring platform, and the locating ring platform is located dodges the step, thereby avoid the first end of filter core and the axial terminal surface of locating ring platform to block, utilize smooth-going transition face to improve the installation smooth and easy degree.

In addition, because the street sweeper carries out the suction of dust and rubbish through the negative pressure produces the device, filter through the filter core after the suction, the air current after the filtration is discharged outwards from radial outlet, consequently with radial outlet towards the oil pump assembly, valve module and electrical component, thereby effectively carry out the heat dissipation of wind energy recycle and equipment, and, utilize the fan to be located the tip of horizontal direction, and the oil pump assembly, valve module and fan all are located the frame on one side based on the axis of width direction, thereby make full use of street sweeper's space, cockpit or other equipment that do not need the heat dissipation then can be arranged to the opposite side of axis, moreover, because the calorific capacity of valve module and oil pump assembly is great, consequently arrange valve module and oil pump assembly near the radial outlet of spiral case, thereby improve the radiating efficiency.

And, because dumping of dustbin subassembly, the lift of brush subassembly and rotatory cleaning all can not function simultaneously, consequently all set up the above-mentioned device in the middle of the A branch road of the steady voltage output of single-way stable flow divider, and arrange through the series connection of switching-over valve, the oil circuit structure has been simplified, optimize the circuit layout of street sweeper, and above-mentioned device does not need simultaneous working, consequently, do not influence the normal operating work of each device, and still with the round brush subassembly that can move simultaneously and negative pressure generating device setting in the B branch road of single-way stable flow divider, consequently, the influence on the rotational speed is the influence only to the influence of oil pressure change in the middle of the B branch road to round brush and fan, its influence is little, and can adopt the series connection of round brush and fan, open the negative pressure suction simultaneously at the start-up round brush, thereby realize high-efficient cleanness.
