The anti-slip hydraulic system being suitable to paddy-field-working of the present invention, including oil-feed port, oil return opening, the first electromagnetic valve and the second electromagnetic valve, described oil-feed port communicates with the outlet line of hydraulic pump, and oil return opening communicates with the return line of hydraulic pump；Oil-feed port is through the first electromagnetic valve to the hydraulic motor fuel feeding of the near front wheel and off hind wheel, and oil-feed port is through the second electromagnetic valve to the hydraulic motor fuel feeding of off-front wheel and left rear wheel, and the oil-out of the hydraulic motor on four wheels communicates with oil return opening；It is particular in that: also including the first valve block and the second valve block, the first valve block and the second valve block and constitute by two choke valves, in same valve block, the oil-in of two choke valves all communicates with oil-feed port；When the first electromagnetic valve and the second electromagnetic valve are under the state turning off oil circuit, oil-feed port is hydraulic motor fuel feeding to the near front wheel and off hind wheel respectively by two choke valves in the first valve block, oil-feed port is hydraulic motor fuel feeding to off-front wheel and left rear wheel respectively by two choke valves in the second valve block, to realize the mean allocation of four hydraulic motor fuel deliveries, also can walk when skidding occurs in wheel。
The anti-slip hydraulic system being suitable to paddy-field-working of the present invention, including the 3rd valve block hydraulic oil in hydraulic system being carried out and heat。
The anti-slip hydraulic system being suitable to paddy-field-working of the present invention, the overfall that described oil-feed port carries out time too high protecting with hydraulic pressure communicates。
The invention has the beneficial effects as follows: the anti-slip hydraulic system being suitable to paddy-field-working of the present invention, under normal walking states, the hydraulic motor of four wheels is carried out fuel feeding by first, second electromagnetic valve by oil-feed port, to order about the walking of hydraulic machinery；When wheel-slip occurs, then first, second electromagnetic valve turns off, stop the fuel feeding to four hydraulic motors, but the hydraulic motor taken turns four by the choke valve in first, second valve block carries out fuel feeding, to realize the mean allocation of fuel feeding, avoid aggravation of skidding, to ensure the hydraulic machinery normal walking when wheel-slip。Having simple and reasonable for structure, beneficial effect is notable and is easy to application a little。
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the anti-slip hydraulic system being suitable to paddy-field-working of the present invention。
In figure: 1 oil-feed port, 2 first electromagnetic valves, 3 second electromagnetic valves, 4 first valve blocks, 5 second valve blocks, 6 oil return openings, 7 the 3rd valve blocks, 8 overfalls。
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described with embodiment。
As shown in Figure 1, give the schematic diagram of the anti-slip hydraulic system being suitable to paddy-field-working of the present invention, it is made up of oil-feed port the 1, first electromagnetic valve the 2, second electromagnetic valve the 3, first valve block the 4, second valve block 5, oil return opening 6, oil-feed port 1 communicates with the oil feed line of hydraulic pump, oil return opening 6 communicates with the return line of hydraulic pump, to realize fuel feeding and the oil return of the hydraulic motor of four wheels。Shown left front A, left front B are respectively used to fuel feeding and the oil return of hydraulic motor on hydraulic machinery the near front wheel, fuel feeding that behind the right side, behind A, the right side, B is respectively used on off hind wheel hydraulic motor and oil return；A before right, right before the B fuel feeding that is respectively used on off-front wheel hydraulic motor and oil return, fuel feeding that left back A, left back B are respectively used on left rear wheel hydraulic motor and oil return。
First shown electromagnetic valve the 2, second electromagnetic valve 3 all has two oil-ins and two oil-outs。Two oil-ins of the first electromagnetic valve 2 are communicated with oil-feed port 1 by a point, and two oil-outs realize respectively to the fuel feeding of hydraulic motor on hydraulic motor, off hind wheel on the near front wheel。Two oil-ins of the second electromagnetic valve 3 are communicated with oil-feed port 1 by a point, and two oil-outs realize respectively to the fuel feeding of hydraulic motor on hydraulic motor, left rear wheel on off-front wheel。The oil return of four upper hydraulic motors of wheel all communicates with oil return opening 6。
When not having wheel that skidding occurs, by first electromagnetic valve the 2, second electromagnetic valve 3, four hydraulic motor fuel feeding can be ensured the normal traveling of hydraulic machinery。But, in the process of paddy-field-working, the existence on the ground of and hollow relatively big due to resistance, when there is skidding in wheel, if or by the first electromagnetic valve 2 and the second electromagnetic valve 3, hydraulic motor is carried out fuel feeding, owing to occurring that the hydraulic motor resistance in slip wheel diminishes, all the other do not occur that the hydraulic oil in skidding oil circuit also can flow in this hydraulic motor, cause slip wheel faster rotational speed, the hydraulic motor not having skidding is short of power so that single-wheel is skidded and caused that this machinery can not be walked。
Therefore, causing the not walking problem of whole hydraulic machinery to solve wheel-slip, be additionally arranged the first valve block 4 and the second valve block 5, the first valve block 4 and the second valve block 5 are constituted by two choke valves。Two choke valves in first valve block 4 and the second valve block 5 are communicated with oil-feed port 1 by a' point, in first valve block 4, the hydraulic motor on the near front wheel, off hind wheel is carried out fuel feeding by the outlet of two choke valves respectively, and the hydraulic motor on off-front wheel, left rear wheel is carried out fuel feeding by the outlet of two choke valves in the second valve block 5 respectively。
In paddy field in the process of operation, when skidding occurs in certain wheel, close the oil feed line in the first electromagnetic valve 2 and the second electromagnetic valve 3, stop the fuel feeding of hydraulic motor on four wheels。Now, the hydraulic oil in oil-feed port 1 is entered by a' point in the choke valve in the first valve block 4 and the second valve block 5。Under the adjustment effect of choke valve, make the oil mass entering four hydraulic motors equal, do not have the conventional hydraulic oil overwhelming majority and enter the phenomenon in the hydraulic motor occurring skidding, ensure that the four of hydraulic machinery hydraulic motor is respectively provided with bigger power, make hydraulic machinery will not stop walking, avoiding hydraulic machinery and stop to walk the generation of phenomenon due to wheel-slip, beneficial effect is notable, is suitable to application。
In order to ensure the cleaning of hydraulic oil in pipeline and there is higher temperature, it is additionally provided with the 3rd valve block 7 with cleaning and heating function。Oil-feed port 1 is also communicated with overfall 8, when the hydraulic fluid pressure in the pipeline of oil-feed port 1 place is bigger, can pass through overfall 8 and overflow, to realize protective effect。
The anti-slip hydraulic system being suitable to paddy-field-working of the present invention, under normal walking states, the hydraulic motor of four wheels is carried out fuel feeding by first, second electromagnetic valve (2,3) by oil-feed port 1, to order about the walking of hydraulic machinery；When wheel-slip occurs, then first, second electromagnetic valve (2,3) turns off, stop the fuel feeding to four hydraulic motors, the hydraulic motor taken turns four by the choke valve in first, second valve block (4,5) carries out fuel feeding, to realize the mean allocation of fuel feeding, avoid aggravation of skidding, with ensure hydraulic machinery one or more take turns skidding time normal walking。
