Abstract
The utility model relates to a dust collecting system structure of a road sweeper, which comprises an engine, a transmission belt, a fan, an airflow passage and an air suction opening which are sequentially connected. The air suction opening is also provided with a suction mouth traveling wheel and two brackets. The structure also comprises a working hydraulic pump for starting the engine, a manual multi-way valve for controlling inlet and outlet liquid of a hydraulic system, and a suction mouth elevation unit. The manual multi-way valve is arranged on an operating table of the sweeper. The working hydraulic pump is respectively connected with the manual multi-way valve and the engine. The suction mouth elevation unit is arranged between the fan and the air suction opening and below the two brackets. The dust collecting system structure has the advantages of adopting the working hydraulic pump to start the engine and utilizing the pressure generated by the hydraulic difference to elevate the air suction mouth so that the damage of the air suction opening due to the contact with a projection object on the ground can be avoided. The whole structure takes the hydraulic system as the power source, thus lowering noise and being environment-friendly.

The utility model solves the problems of the technologies described above by the following technical programs: a kind of dust structure of road sweeper, comprise the motor, a driving-belt, a blower fan, a gas channel, the inlet scoop that connect in turn, place, this inlet scoop also is provided with a suction inlet travel wheel and two supports, it is characterized in that: comprise that also a working solution press pump and that is used for ato unit is used for the manual banked direction control valves of controlled hydraulic system turnover oil, described manual banked direction control valves is arranged on the operating desk of road-sweeper, and described working solution press pump is connected with manual banked direction control valves, motor respectively.
Also comprise a suction inlet lift unit, described suction inlet lift unit is arranged between blower fan and the inlet scoop, and is positioned at the below of two stands.
Described suction inlet lift unit comprise a suction inlet lifting appliance and about two suction inlets that are provided with promote branch, described suction inlet promotes branch and all is connected with the suction inlet lifting appliance, and described arbitrary suction inlet promotes branch and comprises lift cylinder, a pulley assembly, a chain that is used to load static pressure liquid, described lift cylinder is connected with the suction inlet lifting appliance by chain, and described chain all is around on the pulley assembly.
Described lift cylinder is equipped with a piston structure, and piston rod one end of described piston structure is connected with chain.
Be equipped with an oil-in and an oil-out on the described lift cylinder, described oil-in, oil-out are all corresponding with manual banked direction control valves to be connected.
Respectively be provided with a connecting piece about on the described suction inlet lifting appliance, described arbitrary chain is connected with the suction inlet lifting appliance by a described brace.
The end that described piston rod is connected with chain is " U " shape structure, and the openend of described " U " shape structure is connected with chain.
The beneficial effect of the dust structure of the utility model road sweeper is: adopt working hydraulic pressure pump startup motor, the boost in pressure inlet scoop that utilizes hydraulic pressure difference to produce, avoided the inlet scoop to run into the protrusion on ground and impaired, whole dust structure is power source with the hydraulic system, and not only noise is low but also environmental protection.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the schematic diagram of the dust structure of the utility model road sweeper.
Fig. 2 is the operating principle flow chart of the dust structure of the utility model road sweeper.
[specific embodiment]
See also Fig. 1 and Fig. 2, the dust structure of the utility model road sweeper, comprise a motor 1, one blower fan 2, one driving-belt 3, one gas channel 4, one suction inlet travels and takes turns 5, one inlet scoop 6, two supports 7, one suction inlet lift unit 8, the working solution press pump 9 of one ato unit, the manual banked direction control valves 10 of one controlled hydraulic system liquid in-out, described two supports 7 are fixed on the road-sweeper propons, the dust structure is fixedlyed connected with road-sweeper, described manual banked direction control valves 10 is arranged on the operating desk of road-sweeper, described working solution press pump 9 all with manual banked direction control valves 10, motor 1 connects, described suction inlet lift unit 8 is arranged between blower fan 2 and the inlet scoop 6, and be positioned at the below of two stands 7, described suction inlet lift unit 8 comprise a suction inlet lifting appliance 81 and about two suction inlets that are provided with promote branch 82, described suction inlet promotes branch 82 and all is connected with suction inlet lifting appliance 81, and described arbitrary suction inlet promotes branch 82 and comprises a lift cylinder 821 that is used to load static pressure liquid, one pulley assembly 822, one chain 823, described lift cylinder 821 is connected with suction inlet lifting appliance 81 by chain 823, described chain 823 all is around on the pulley assembly 822, piston rod 8,211 one ends of described lift cylinder 821 are connected with chain 823, and be equipped with an oil-in 8212 and an oil-out 8213 on the described lift cylinder 821, described oil-in 8212, oil-out 8213 all with manual 10 corresponding connections of banked direction control valves, described suction inlet lifting appliance about 81 respectively is provided with a connecting piece 811, described chain 823 is connected with suction inlet lifting appliance 81 by brace 811, the end that described piston rod 8211 is connected with chain 823 is " U " shape structure, and the openend of described " U " shape structure is connected with chain 823.
