Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil tanks, in particular to a dual-channel hydraulic oil tank device. Background Art

[0002] The main function of the hydraulic oil tank is to store hydraulic oil, provide a stable oil source for the hydraulic system, and filter the hydraulic oil to reduce the particulate matter in the hydraulic oil. After the hydraulic oil tank has been used for a period of time, it needs to be cleaned and the hydraulic oil replaced.

[0003] In the related technology, a search revealed a scheme of a hydraulic oil tank for micro excavators (CN219622964U), which integrates a breathing valve mounting port and an oil return port on the oil inlet and return filter cover to cooperate with the oil suction mechanism and the oil return mechanism in the tank body, thereby effectively reducing the size of the tank body through a new layout.

[0004] The above-mentioned hydraulic oil tank is a commonly used type. However, when cleaning this type of hydraulic oil tank, it is necessary to unscrew several bolts to remove the inlet and return oil filter covers, and the size of the inlet and return oil filter covers is smaller than the tank body. After removing the inlet and return oil filter covers, if the oil stains in the tank body need to be cleaned, the operating space is small, and replacing the oil suction filter and the oil return filter requires blind operation, which is not convenient enough. Utility Model Content

[0011] The support rod can be removed by loosening the fixing cap, and the oil filter can be taken down through the support rod. The operation space for replacing the oil filter is large, blind operation can be avoided, and the installation of the oil filter is easier.

[0012] Furthermore, a screwing ring is fixedly connected to the surface of the clamping ring, and the clamping ring can be screwed using the screwing ring, and the steel roller is inserted into the screwing ring, which saves effort when loosening and tightening the clamping ring.

[0013] Furthermore, a spring is connected to the inner wall of the ventilation cover, and the lower end of the spring is against the upper surface of the air filter element. The air filter element is pressed by the elastic force of the spring to ensure that the air filter element is sealed and connected to the support tube to prevent the air filter element from loosening.

[0014] Furthermore, two sealing rings are sleeved on the surface of the box cover, and the sealing rings are against the inner wall of the box body, thereby improving the sealing performance of the connection between the box body and the box cover and preventing leakage of hydraulic oil.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) Separate the oil filter from the box cover by means of a compression ring, and then rotate the stud with the fixed seat as the fulcrum. Then the box cover can be removed, so that the box body is in an open state. When cleaning the inner wall of the box, the operating space is larger, the box body is cleaned more thoroughly, and there is sufficient space for disassembling and installing the oil filter, which improves the efficiency and deformability of replacement.

[0017] (2) The support rod and the support plate are separated by twisting the fixing cap. The support rod can be used to drive the oil filter to be separated from the oil outlet joint and the oil inlet joint. The oil filter can be replaced easily. The oil filter can filter particulate matter to ensure the normal operation of the hydraulic equipment. BRIEF DESCRIPTION OF THE DRAWINGS
