Abstract
The utility model discloses an excavator hydraulic oil tank which comprises a tank body and an oil return cavity. The oil return cavity comprises an oil return upper cavity and a plurality of cylinder cavities, wherein the oil return upper cavity is a cavity which is formed by a first side plate, a partition plate, a second side plate, a supporting plate and a top plate in a welding mode, each cylinder cavity is composed of a cylinder and a flange in a welding mode, and the upper end face of each cylinder is higher than the partition plate. According to the excavator hydraulic oil tank, the oil return cavity of the excavator hydraulic oil tank is divided into two parts, the cylinder cavities are arranged, an oil return filter is installed inside each cylinder cavity, and the oil return filters enhance filter capacity; due to the fact that the upper end face of each cylinder is higher than the partition plate, foreign bodies in oil can precipitate on the partition plate in the oil returning process, and the foreign bodies are prevented from entering the system in the filter core replacing process; the inner diameter of each cylinder is larger than the outer diameter of each filter, the structure enables filter cores to be positioned conveniently in the replacing process, the filter cores only need to be placed inside the cylinders, and practicability is achieved in practical work.
Description
Technical field
The utility model relates to a kind of excavator hydraulic oil container, belongs to engineering machinery field.
Background technique
The hydraulic oil container majority of excavator is single filter core cavity type at present, it is the cavity that a sealing is arranged in the hydraulic oil container, place a return filter in the cavity, this type hydraulic oil container is simple in structure, cost is low, its defective is: filter capacity is low, in the filter core replacing process in location difficulty, the filter core replacing process in the fuel tank foreign matter of precipitation enter hydraulic system easily, cause hydraulic element impaired.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of excavator hydraulic oil container, and it is convenient that this fuel tank beautiful shape, filter capacity are strong, filter core is changed, and can reduce foreign matter and enter hydraulic system.
In order to achieve the above object, a kind of excavator hydraulic oil container comprises casing and oil back chamber, and described oil back chamber is made up of oil return epicoele and a plurality of cylinder chamber, and described oil back chamber is positioned at the box house upper end; Described oil return epicoele is the cavity that is welded by side plate one, dividing plate, side plate two, support plate and top board; Described cylinder chamber is welded by cylinder and flange, and the upper-end surface of cylinder is higher than dividing plate, a return filter is installed in described each cylinder chamber, the base plate of described return filter is connected by screw with the flange of cylinder chamber bottom, leave the used circular hole of oil return on the flange, hydraulic oil at first enters by cylinder, flange in the bottom, in the formed annular housing of cylindrical return filter outer surface, behind the filter filtering layer, enter the cylindrical filter inner chamber body, filter inner chamber body bottom links to each other with the flange in the bottom circular hole, enters the hydraulic oil container bottom through circular hole on the flange again through the fluid of filter element filtering.
Described cylinder chamber has three, and its internal diameter is a bit larger tham the external diameter of return filter, and filter core only needs be put into filter core in the cylinder when changing and gets final product like this.
The beneficial effects of the utility model are: compare with prior art, the utility model is divided into two-part with the oil back chamber of hydraulic oil container, and a plurality of cylinder chambers are set, and installs back oil strainer in the cylinder chamber, and many filter element filterings increase filter capacity; The upper-end surface of cylinder chamber is higher than dividing plate, and in the oil return process, foreign matter can be deposited on the dividing plate in the fluid like this, has avoided foreign matter to enter system; In the filter core replacing process, because barrel bore is big slightly than the return filter external diameter, only needs when filter core is changed be put into filter core in the cylinder and get final product, the structure of cylinder chamber makes filter core change process filter core location conveniently.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1, the oil return epicoele, 2, side plate one, 3, cylinder chamber, 4, dividing plate, 5, side plate two, 6, support plate, 7, cylinder, 8, flange, 9, top board, 10, casing.
Embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
As shown in Figure 1, a kind of excavator hydraulic oil container comprises casing 10 and oil back chamber, and described oil back chamber is made up of oil return epicoele 1 and a plurality of cylinder chamber 3, and described oil back chamber is positioned at casing 10 inner upper end; Described oil return epicoele 1 is the cavity that is welded by side plate 1, dividing plate 4, side plate 25, support plate 6 and top board 9; Described cylinder chamber 3 is welded by cylinder 7 and flange 8, and the upper-end surface of cylinder 7 is higher than dividing plate 4, in described each cylinder chamber 3 return filter is installed, the flange 8 of the base plate of described return filter and cylinder chamber 3 bottoms is connected by screw, oil return epicoele 1 is shunted hydraulic oil by three cylinder chambers 3, and be separately installed with a return filter in each cylinder chamber 3, many filter element filterings increase filter capacity; Because cylinder chamber 3 upper-end surfaces exceed the height of dividing plate 4, foreign matter can be deposited on the dividing plate 4 in the fluid in the oil return process, has avoided in the filter core replacing process, and foreign matter enters system; Cylinder chamber 3 adopts high-accuracy weldless steel tube to make, and the internal diameter of cylinder chamber 3 is a bit larger tham the return filter external diameter, so only need filter core is put into cylinder chamber 3 interior getting final product, it is convenient that this structure makes filter core change process filter core location.
Leave the used circular hole of oil return on the flange, hydraulic oil flows in the cylinder chamber 3, behind the return filter filter element filtering, enter the return filter cylindrical cavity, filter inner chamber body bottom links to each other with flange in the bottom 8 circular holes, enters the hydraulic oil container bottom through circular hole on the flange 8 again through the fluid of filter element filtering.
