One valve block and the second valve block, the first valve block and the second valve block are constituted by two choke valves, and in same valve block, two choke valves enters
Hydraulic fluid port is communicated with oil-feed port；In the state of the first magnetic valve and the second magnetic valve are in turning off oil circuit, oil-feed port passes through
The hydraulic motor fuel feeding respectively to the near front wheel and off hind wheel of two choke valves in first valve block, oil-feed port is by the second valve block
Two choke valves hydraulic motor fuel feeding respectively to off-front wheel and left rear wheel, to realize the average of four hydraulic motor fuel deliveries
Distribution, can also walk when skidding occurs in wheel.
The anti-slip hydraulic system for being suitable to paddy-field-working of the present invention, including cleaning to the hydraulic oil in hydraulic system
With the 3rd valve block of heating.
The anti-slip hydraulic system for being suitable to paddy-field-working of the present invention, the oil-feed port are protected when too high with hydraulic pressure
Overfall is communicated.
The invention has the beneficial effects as follows：The anti-slip hydraulic system for being suitable to paddy-field-working of the present invention, in normal walking shape
Under state, oil-feed port carries out fuel feeding to the hydraulic motor of four wheels by first, second magnetic valve, to order about the row of hydraulic machinery
Walk；In the case of there is wheel-slip, then first, second electromagnetism valve breakdown, stops the fuel feeding to four hydraulic motors, but
Fuel feeding is carried out to the hydraulic motor on four wheels by the choke valve in first, second valve block, to realize the mean allocation of fuel feeding,
Aggravation of skidding is avoided, to ensure normal walking of the hydraulic machinery in wheel-slip.With simple and reasonable for structure, beneficial effect
Significantly and it is easy to application a little.
Description of the drawings
Fig. 1 is the schematic diagram of the anti-slip hydraulic system for being suitable to paddy-field-working of the present invention.
In figure：1 oil-feed port, 2 first magnetic valves, 3 second magnetic valves, 4 first valve blocks, 5 second valve blocks, 6 oil return openings, 7
Three valve blocks, 8 overfalls.
Specific embodiment
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, giving the schematic diagram of the anti-slip hydraulic system for being suitable to paddy-field-working of the present invention, which is by fuel feeding
Mouthful the 1, first magnetic valve 2, the second magnetic valve 3, the first valve block 4, the second valve block 5, oil return opening 6 are constituted, oil-feed port 1 and hydraulic pump
Oil feed line is communicated, and oil return opening 6 is communicated with the return line of hydraulic pump, to realize the fuel feeding of the hydraulic motor of four wheels and return
Oil.Shown left front A, left front B is respectively used to the fuel feeding of hydraulic motor and oil return on hydraulic machinery the near front wheel, B after A behind the right side, the right side
It is respectively used to the fuel feeding of hydraulic motor and oil return on off hind wheel；Before right, A, right front B are respectively used to the confession of hydraulic motor on off-front wheel
Oil and oil return, left back A, left back B are respectively used to the fuel feeding of hydraulic motor and oil return on left rear wheel.
Shown the first magnetic valve 2, the second magnetic valve 3 have two oil-ins and two oil-outs.First magnetic valve 2
Two oil-ins are communicated with oil-feed port 1 by a points, and two oil-outs are realized respectively on hydraulic motor, off hind wheel on the near front wheel
The fuel feeding of hydraulic motor.Two oil-ins of the second magnetic valve 3 are communicated with oil-feed port 1 by a points, and two oil-outs are realized respectively
Fuel feeding to hydraulic motor on hydraulic motor, left rear wheel on off-front wheel.The oil return of the upper hydraulic motor of four wheels with 6 phase of oil return opening
It is logical.
When skidding occurs in no wheel, supplied by the first magnetic valve 2,3 pairs of four hydraulic motors of the second magnetic valve
Oil can ensure the normally travel of hydraulic machinery.However, during paddy-field-working, the ground of and hollow larger due to resistance
Exist, when skidding occurs in wheel, if or carried out to hydraulic motor by the first magnetic valve 2 and the second magnetic valve 3
Fuel feeding, as the hydraulic motor resistance occurred in slip wheel diminishes, there is not the hydraulic oil in skidding oil circuit in remaining
Also can flow in the hydraulic motor, cause slip wheel faster rotational speed, the hydraulic motor for not having skidding is short of power so that
Single-wheel is skidded and causes this machinery walk.
Therefore, the not walking problem of whole hydraulic machinery is caused to solve wheel-slip, is additionally arranged the first valve block 4
With the second valve block 5, the first valve block 4 and the second valve block 5 are constituted by two choke valves.In first valve block 4 and the second valve block 5 two
Individual choke valve is communicated with oil-feed port 1 by a' points, and in the first valve block 4, the outlet of two choke valves is respectively to the near front wheel, off hind wheel
On hydraulic motor carry out fuel feeding, the outlet of two choke valves in the second valve block 5 is respectively to the hydraulic pressure on off-front wheel, left rear wheel
Motor carries out fuel feeding.
In paddy field during operation, when skidding occurs in certain wheel, the first magnetic valve 2 and second is closed electric
Oil feed line in magnet valve 3, stops the fuel feeding to hydraulic motor on four wheels.Now, the hydraulic oil in oil-feed port 1 passes through a'
Point is in the choke valve in the first valve block 4 and the second valve block 5.Under the adjustment effect of choke valve so that into four hydraulic pressure
The oil mass of motor is equal, is not in the phenomenon that the conventional hydraulic oil overwhelming majority is entered in the hydraulic motor for occurring skidding, it is ensured that
Four hydraulic motors of hydraulic machinery are respectively provided with larger power so that hydraulic machinery will not stop walking, it is to avoid hydraulic pressure
Machinery stops to walk the generation of phenomenon due to wheel-slip, and beneficial effect significantly, is suitable to application.
In order to ensure in pipeline the cleaning of hydraulic oil and with higher temperature, be additionally provided with cleaning and heating function
The 3rd valve block 7.Oil-feed port 1 is also communicated with overfall 8, when the hydraulic fluid pressure in 1 place pipeline of oil-feed port is larger, can lead to
Cross overfall 8 to overflow, to realize protective effect.
The anti-slip hydraulic system for being suitable to paddy-field-working of the present invention, under normal walking states, oil-feed port 1 is by the
First, the second magnetic valve（2、3）Fuel feeding is carried out to the hydraulic motor of four wheels, to order about the walking of hydraulic machinery；When there is wheel
In the case of skidding, then first, second magnetic valve（2、3）Shut-off, stops fuel feeding to four hydraulic motors, by first, the
Two valve blocks（4、5）In choke valve to four wheel on hydraulic motor carry out fuel feeding, to realize the mean allocation of fuel feeding, it is to avoid beat
Sliding aggravation, to ensure normal walking of the hydraulic machinery when one or more wheels skid.
