Description
Technical field
The invention belongs to sweeping machine component technology field, be specifically related to a kind of electrodeless adjustment air pressure antiwear device of sweeping machine brush.
Background technology
Sweeping machine is by brush and earth surface and is rotated by motor driving brush, is rotated by brush by ground rubbish and is transplanted on suction nozzle front, is then inhaled by suction nozzle and picks up in refuse bin, reaches to clean the effect on road surface.But, if brush is pressed onto on ground by self gravitation, bigger frictional force can be produced, frictional force is crossed conference and is caused that quick-wearing is crossed in brush, it is therefore necessary to regulate brush ground pressure.Tradition sweeping machine is by spring tension or mechanical position limitation adjustment ground pressure, but this kind of method, ground pressure is difficult to regulate accurately, and with the abrasion of brush, it is necessary to regulate at any time, time-consuming.
Summary of the invention
For the drawbacks described above overcoming prior art to exist, it is an object of the invention to, a kind of electrodeless adjustment air pressure antiwear device of sweeping machine brush is provided, utilize step-less adjustment air pressure that brush is produced suitable lifting force, reducing the pressure of brush and ground generation thus reducing the frictional force that brush produces with ground, reducing the rate of wear of brush.
The electrodeless adjustment air pressure antiwear device of sweeping machine brush provided by the invention, including brush, air-path control system, brush supporting construction, connecting rod, described air-path control system includes cylinder, shuttle valve, lock valve, solenoid directional control valve, air relief valve, source of the gas, and described solenoid directional control valve includes two five electric change valves and 2/2-way solenoid directional control valve；Described source of the gas connects two-way pipeline and switches between two-way pipeline, and two five electric change valves of leading up to are sequentially connected with lock valve, shuttle valve, cylinder, and 2/2-way solenoid directional control valve of separately leading up to is sequentially connected with air relief valve, shuttle valve, cylinder；Described shuttle valve is or gate shuttle valve, and two air inlets connect lock valve and air relief valve respectively, and gas outlet connects cylinder；Described air-path control system is also associated with deafener.
The electrodeless adjustment air pressure antiwear device of sweeping machine brush provided by the invention, it has the beneficial effects that, by step-less adjustment air pressure, can accurately set the contact pressure of brush and ground, after contact pressure is adjusted, without carrying out manual adjustment further according to sweeping road wear extent, can also more effective control brush wear extent while convenient and practical.

Detailed description of the invention
With reference to the accompanying drawings, in conjunction with an embodiment, the electrodeless adjustment air pressure antiwear device of sweeping machine brush provided by the invention is described in detail.
Embodiment
With reference to Fig. 1-Fig. 3, the electrodeless adjustment air pressure antiwear device of sweeping machine brush of the present embodiment, including brush 4, air-path control system, brush supporting construction 2, connecting rod 3, described air-path control system includes cylinder 1, shuttle valve 11, lock valve 7, solenoid directional control valve, air relief valve 10, source of the gas 8, and described solenoid directional control valve includes two five electric change valves 6 and 2/2-way solenoid directional control valve 9；Described source of the gas 8 connects two-way pipeline and switches between two-way pipeline, two five electric change valves 6 of leading up to are sequentially connected with lock valve 7, shuttle valve 11, cylinder 1, and 2/2-way solenoid directional control valve 9 of separately leading up to is sequentially connected with air relief valve 10, shuttle valve 11, cylinder 1；Described shuttle valve 11 is or gate shuttle valve, and two air inlets connect lock valve 7 and air relief valve 10 respectively, and gas outlet connects cylinder 1；Described air-path control system is also associated with deafener 5.
With reference to Fig. 2-Fig. 3, source of the gas 8 continues to supply to whole system, source of the gas 8 by two five electric change valves 6, lock valve 7, shuttle valve 11 to cylinder 1 high pressure gas is provided time, cylinder 1 shrinks, brush 4 retracted state；As need brush 4 land work time, described two five electric change valves 6 are left on ventilation after receiving the signal of telecommunication, described lock valve 7 is opened, cylinder loculus is connected with air, brush 4 is stretched out brush 4 by deadweight band dynamic air cylinder 1 and is landed, described 2/2-way solenoid directional control valve 9 receives a signal of telecommunication automatically afterwards, valve block moves right and opens ventilation, high pressure gas becomes low pressure gas by described air relief valve 10, eventually passing described shuttle valve 11 by low pressure gas supply cylinder loculus, brush 4 is produced lifting force upwards by cylinder loculus.Air pressure is adjusted through described air relief valve 10, the lifting force that cylinder loculus produces is slightly lower than brush 4 and conducts oneself with dignity, therefore the N(normal pressure that ground is produced by brush 4 is substantially reduced), thus reducing brush 4 to produce F(frictional force with ground), level reduces greatly the rate of wear of brush 4.
