Abstract

The utility model relates to a hydraulic oil tank of a loader. The hydraulic oil tank is provided with a tank body, a return oil filter element, a sealed oil return drum, an oil conduit, an oiling filter element, a partition plate, an oil pump, an oil suction pipe of the oil pump and an air filter, wherein the tank body is internally provided with an oil return cavity and an oil outlet cavity which are partitioned by the partition plate; the return oil filter element is arranged in the sealed oil return drum; the sealed oil return drum is fixedly arranged at the top of the oil return cavity through a fastener, and the lower end of the sealed oil return drum is communicated with the oil conduit; the oiling filter element is arranged an oil port of the oil outlet cavity; the oil pump is connected to the lower side surface of the oil outlet cavity through the oil suction pipe of the oil pump; and the air filter is fixedly arranged at the oil port at the top of the oil outlet cavity through a fastener. The oiling filter element of the hydraulic oil tank is arranged at the oil port of the oil outlet cavity, so that sundries are prevented from falling into the oil tank during oiling; the sealed oil return drum is adopted, so that the phenomenon that return oil directly flows into the oil outlet cavity without passing through the return oil filter element is avoided; and the oil return cavity and the oil outlet cavity are separated by the partition plate, so that the return oil is prevented from directly flowing into the oil outlet cavity.

Description

The loader hydraulic fuel tank

Technical field

The utility model relates to a kind of hydraulic oil container, particularly a kind of loader hydraulic fuel tank.

Background technique

The present stage cleaning, oil return filter, fuel-displaced mode etc. of loader hydraulic fuel tank is to affect one of stable key factor of complete machine hydraulic system, and therefore, the structure of appropriate design hydraulic oil container just can obtain better economic benefits.Traditional hydraulic oil container exists and difficultly cleans, oil pump is easily inhaled after sky, oil return filter oil and directly is discharged to the fuel tank bottom and makes the sludge of bottom be mixed out the defectives such as oil pocket.

The model utility content

The purpose of this utility model is to overcome the defective that prior art exists, and provides a kind of structural configuration simple, and applicability is wide, is applicable to mate the loader hydraulic fuel tank of various loaders.

The technological scheme that realizes the utility model purpose is: a kind of loader hydraulic fuel tank has casing, oil return filter core, sealing oil returning tube, oil guide pipe, oil filling filter core, dividing plate, oil pump suction tube and oil pump; Have the oil back chamber that separates through dividing plate in described casing and go out oil pocket; Described oil return filter core is arranged in the sealing oil returning tube; Described sealing oil returning tube is fixedly mounted on the top of oil back chamber by fastening piece, sealing oil returning tube lower end and oil guide pipe UNICOM; Described oil filling filter core is arranged on out the oil filler of oil pocket; Described oil pump is connected to out the downside of oil pocket by oil pump suction tube; Also has air-strainer; Described air-strainer is fixedly mounted on the oil filler of fuel-displaced top of chamber by fastening piece.

Have reticulated cell on the tube wall of the described oil guide pipe of technique scheme, the bottom of oil guide pipe is provided with the sealing base plate.

Has level meter on the described casing outer side surface of technique scheme.

The described bottom half of technique scheme is provided with the seat of draining the oil.

Be fixed with hinge on the described casing of technique scheme.

The described hinge welding of technique scheme is arranged on casing.

After adopting technique scheme, the utlity model has following positive effect:

(1) filter rationally: oil filling filter core is arranged on out the oil filler of oil pocket, has foreign material to drop in fuel tank when having avoided oiling; Adopt the sealing oil returning tube, avoid oil return to flow directly into out oil pocket without the oil return filter core, have reticulated cell on the tube wall of oil guide pipe, the bottom of oil guide pipe is provided with the sealing base plate, makes oil flow to fuel tank from the oil guide pipe side, avoids the sludge of bottom to be mixed out oil pocket; And oil back chamber and go out oil pocket and have dividing plate separately avoids oil return to flow directly into out oil pocket.

(2) anti-oil pump is inhaled empty: oil pump is connected to out the downside of oil pocket by oil pump suction tube, oil pump is from the downside oil suction, when preventing that oil pump power is inadequate, oil is inhaled empty because self-gravity action causes, count in liquid feeding position, the outside, be easy to observe the liquid level of Fuel Oil Remaining in fuel tank, prevent the suction sky that fuel tank oil causes not.

(3) easily clean: when cleaning fuel tank, only need not being that hinge bolt is on one side turned on, oil suction and oil return flange to be pulled down, then rotate fuel tank to the position of easy cleaning, just can clear up, after cleaning out, then rotate fuel tank and return original position.
