Abstract
The utility model discloses a hydraulic oil tank for small engineering machinery. The hydraulic oil tank comprises an oil tank body (5), an oil return one-way valve (7), an oil return flange (6), an oil return filter (4), an oil suction flange (2), an oil suction filter (1), a main oil return hole (8), an oil leaking hole (3), a breather (9) and two baffles (10), wherein the two baffles are arranged in the oil tank body and form a closed cavity body together with the inner side of a top plate of the oil tank body and the inner side wall of the oil tank body; the oil return filter is fixed at the lower part of the cavity body and communicated with the cavity body, the main oil return hole and the oil return one-way valve are fixed on the outer side of the top plate of the oil tank body through the oil return flange and communicated with the cavity body, the oil suction filter is transversely arranged at the bottom of the oil tank body, and one end of the oil suction filter is connected with the oil suction flange; the oil leaking hole is formed in the outer side of the side wall of the oil tank body, and the breather is arranged on the top plate of the oil tank body. According to the hydraulic oil tank, the welding is simple, the mutual interference between the oil suction filter and the oil return filter is avoided, and the normal operation of a hydraulic system is guaranteed.
Description
Technical field
The utility model relates to a kind of hydraulic oil container, and specifically a kind of hydraulic oil container for small engineering machinery, belongs to hydraulic oil container technical field.
Background technique
At present, because the complete machine of small engineering machinery is arranged very compact, and hydraulic system has higher requirement for the volume of hydraulic oil container, so how to ensure the enough hydraulic oil containers of layout capacity in less space, become a difficult point of small engineering machinery design.
To there is the shortcoming of the following aspects as being used on small engineering machinery in hydraulic oil container of the prior art:
1. return check valve, in the side of oil box, has increased the boundary dimension of hydraulic oil container, will cause the interference with miscellaneous part.
2. the oil back chamber outside return filter occupies larger fuel tank space, causes the actual volume of hydraulic oil container to reduce, and is difficult to meet the requirement of the normal work of hydraulic system.
3. oil absorption filter, perpendicular to the assembling of fuel tank bottom surface, because the sectional area of hydraulic oil container is less, will cause oil absorption filter and return filter to be interfered.
4. in oil box, between return filter and oil absorption filter, have dividing plate, welding procedure complexity, is difficult to realize.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of hydraulic oil container for small engineering machinery, welds simply, avoids oil absorption filter and return filter to interfere mutually and interferes, and guarantee hydraulic system is normally worked.
To achieve these goals, the technical solution adopted in the utility model is: this is used for the hydraulic oil container of small engineering machinery, comprise oil box, return check valve, oil return flange, return filter, oil suction flange, oil absorption filter, main return opening, drain tap, resuscitation apparatus and two baffle plates, two baffle plates are arranged on oil box inside, and the top board inner side of two baffle plates and oil box and the madial wall of oil box form the cavity body of sealing; Return filter is fixed on cavity body bottom and connects and be connected with cavity body, main return opening is fixed on the top board outside of oil box and is connected and be connected with cavity body by oil return flange with return check valve, oil absorption filter is horizontally installed on oil box bottom, and its one end is connected with oil suction flange; Drain tap is located at the sidewall outside of oil box, and resuscitation apparatus is arranged on the top board of oil box.
Further, the longitudinal profile of described cavity body be shaped as rectangle.
Further, between the madial wall of the top board of two described baffle plates, oil box inner side and oil box, be welding.
Compared with prior art, the utility model adopts oil absorption filter and return filter to divide and is arranged, and return filter is connected with the cavity body of sealing, avoiding oil absorption filter and return filter to interfere mutually interferes, without carry out dividing plate welding between oil absorption filter and return filter, welding procedure is become simply, increase the actual volume of hydraulic oil container simultaneously, guarantee hydraulic system is normally worked.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1, oil absorption filter, 2, oil suction flange, 3, drain tap, 4, return filter, 5, oil box, 6, oil return flange, 7, return check valve, 8, main return opening, 9, resuscitation apparatus, 10, baffle plate.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises oil box 5, return check valve 7, oil return flange 6, return filter 4, oil suction flange 2, oil absorption filter 1, main return opening 8, drain tap 3, resuscitation apparatus 9 and two baffle plates 10, two baffle plates 10 are arranged on oil box 5 inside, and two baffle plates 10 form the cavity body of sealing with the top board inner side of oil box 5 and the madial wall of oil box 5; Return filter 4 is fixed on cavity body bottom and connects and be connected with cavity body, main return opening 8 is fixed on the top board outside of oil box 5 and is connected and be connected with cavity body by oil return flange 6 with return check valve 7, oil absorption filter 1 is horizontally installed on oil box 5 bottoms, and its one end is connected with oil suction flange 2; Drain tap 3 is located at the sidewall outside of oil box 5, and resuscitation apparatus 9 is arranged on the top board of oil box 5.
Preferably, the longitudinal profile of cavity body be shaped as rectangle, this shape is convenient to staff's welding, enhances productivity.
Further, between the madial wall of the top board of two described baffle plates 10, oil box 5 inner side and oil box 5, be welding; Compared with integrally casting, weld the staff's processing of being more convenient for.
When use, the utility model is placed on small engineering machinery, just can meets the demand of the normal work of hydraulic system.
