Fig. 2 is the pilot valve hydraulic control mode of the present invention；
In figure：1st, hydraulic oil container, 2, duplex pump, 3, distributing valve, 4, swing arm cylinder, 5, tipping bucket cylinder, 6, clean motor, 7, electromagnetic switch Valve, 8, watering motor, 9, overflow valve, 10, oil return cleaner, 11, check valve.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in figure 1, a kind of hydraulic control watering purging system of the invention, including hydraulic oil container 1, duplex pump 2, distributing valve 3rd, swing arm cylinder 4, tipping bucket cylinder 5, clean motor 6, solenoid directional control valve 7, watering motor 8, overflow valve 9, oil return cleaner 10 and unidirectional Valve 11；The front pump oil-out of duplex pump 2 connects the oil inlet of distributing valve 3；Hydraulic fluid port and solenoid directional control valve 7 are pumped out after duplex pump 2 P mouths be connected, the overfall of duplex pump 2 takes back hydraulic oil container 1；Distributing valve 3 is three distributing valves, and the A1 mouths of distributing valve 3 are with turning over The rodless cavity of oil cylinder 5 that struggles against is connected, and the B1 mouths of distributing valve 3 are connected with the rod chamber of dump ram 5；The A2 mouths of distributing valve 3 and boom cylinder 4 Rodless cavity is connected, and the B2 mouths of distributing valve 3 are connected with the rod chamber of boom cylinder 4；A3, B3 mouth of distributing valve 3 are respectively with cleaning motor 6 Oil inlet, oil-out be connected；The T mouths of distributing valve 3 are connected with the oil return opening of hydraulic oil container 1；Watering motor 8 is reversing motor, The watering drain tap of motor 8 connects hydraulic oil container 1, and the oil inlet and outlet for motor 8 of sprinkling water is connected by check valve 11；Solenoid directional control valve 7 A, B mouthfuls are connected with watering motor 8, and the T mouths of solenoid directional control valve 7, which connect, returns hydraulic oil container 1 after overflow valve 9.Wherein, the control of distributing valve 3 Mode processed can be Mechanical course.Can also be as shown in Fig. 2 being integrated with pilot valve in distributing valve 3, the control mode of distributing valve 3 is Pilot valve hydraulic control.
On the basis of said structure, oil return cleaner 10 is connected between the T mouths and hydraulic oil container 1 of distributing valve 3 of the present invention, To filter the impurity in fluid, fluid cleaning is kept.In addition, pilot valve can be that is, first with integrated solenoid directional control valve operating function The integrated solenoid directional control valve control button of pilot valve, or not integrated magnet valves operating function, using mechanical control.
The present invention removes original scraper bowl on the basis of original loading machine, will clean equipment and is arranged on carrying for loading machine Rise with tipping bucket system, control cleans the lifting and upset of equipment, the valve of hydraulic system two is changed to three valves, and operator is driving Room operating control handle is sailed, the hydraulic energy that hydraulic pump is provided inputs casing both sides by three distributing valves 3 and oil line pipe Hydraulic motor makes its work, so as to be converted into mechanical energy, then sweeps roller rotation by driving-chain drive, sweeps roller and generation is contacted with ground Roll cast power, most material rubbish is swept in cleaning box body at last.The watering horse at car body rear is controlled by solenoid directional control valve 7 simultaneously Up to 8, sprinkler system is driven, ground is thoroughly cleaned.After casing is filled, operating personnel operation loader cab in lifting and Material rubbish is discharged to specified location by handle reverse.
The operation principle of hydraulic control of the present invention watering purging system is：Hydraulic pump is driven by engine, when starting Machine work is driven after the normal work of duplex pump 2, and pump pressure oil is introduced the P mouths of solenoid directional control valve 7 by pipeline after duplex pump 2.
If solenoid directional control valve 7 is failure to actuate（In middle position）：Duplex pump 2 rear pump pressure oil through the oil return box of overflow valve 9, simultaneously Other functions are supplied to use.If solenoid directional control valve 7 is acted：When solenoid directional control valve 7 is in left position, fluid enters watering motor 8, band Dynamic watering motor 8 rotates, and carries out watering operation, and the oil return of watering motor 8 returns to fuel tank, while supplying other by overflow valve 9 Function is used.When solenoid directional control valve 7 by left position switches to right position, watering motor 8 continues to rotate due to inertia, watering motor 8 Oil-out is connected by check valve 11 with the oil inlet for motor 8 of sprinkling water, and is given the watering repairing of motor 8, is prevented motor from damaging.
Certainly, above-described embodiment is only the preferred scheme of the present invention, is specifically not limited thereto, on this basis can basis It is actually needed and makes with targetedly adjusting, so as to obtain different embodiments.Because mode in the cards is more, this In just no longer illustrate one by one.
