[0018] In order to make the purpose, the technical scheme and the advantages of the utility model more clear and explicit, the utility model is further described in detail in combination with the drawings and the embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0019] As shown in the accompanying drawings Figure 1The shown integrated hydraulic oil tank assembly includes an oil tank body 1, an oil suction filter 2 and an oil return filter 3 arranged inside the oil tank body 1, an oil tank cover plate 4 with integrated filter mounting positions and oil filling port mounting positions fixedly installed on the top of the oil tank body 1, and a fixing member 5 for adsorbing iron filings attached to the bottom of the oil tank body 1, and a drain member one 6 and a drain member two 7 fixedly installed on the side and bottom of the bottom of the oil tank body 1 respectively;

[0020] The filter mounting positions of the oil tank cover plate 4 are connected with the oil suction filter 2 and the oil return filter 3 through pipelines respectively;

[0021] The oil filling port mounting positions of the oil tank cover plate 4 are fixedly installed with oil filling port covers 8 with breathers.

[0022] Among them, the oil tank body 1 is the main part for storing hydraulic oil, which is manufactured by high-strength welding process to ensure stable structure and no leakage; and the welding method of the oil tank cover plate 4 and the oil tank body 1 is full welding or local welding to ensure the strength and sealing performance of the connection.

[0023] Among them, the oil suction filter 2 and the oil return filter 3 are located at appropriate positions inside the oil tank body 1 and integrated at the filter mounting positions of the oil tank cover plate 4; the hydraulic oil entering the oil tank body 1 is filtered by the oil suction filter 2 and the hydraulic oil returning to the oil tank body 1 is filtered by the oil return filter 3 to ensure clean oil quality and prolong the service life of the corresponding hydraulic system; and the oil suction filter 2 and the oil return filter 3 are both designed with replaceable filter elements for regular replacement to maintain the filtering effect.

[0024] Among them, the oil tank cover plate 4 is integrated with the filter mounting positions and the oil filling port mounting positions as an integrated carrier, which is connected with the oil tank body 1 by precise welding to form an integrated structure;

[0025] Among them, the material of the fixing member 5 is set as a strong magnetic material; for example, the fixing member 5 is a strong magnet, which not only effectively adsorbs the bottom of the oil tank body 1, but also adsorbs the metal particles, such as iron filings, that may be contained in the hydraulic oil in the oil tank body 1, so as to prevent the corresponding hydraulic system from being damaged, i.e. to reduce system wear;

[0026] Among them, the oil filling port cover 8 with a breather includes a dust screen and a splash-proof cover to prevent dust, moisture and foreign matter from entering the oil tank body 1 during oil filling operation, and the breather is used to adjust the air pressure balance between the inside and outside of the oil tank body 1 to prevent oil leakage caused by pressure difference; so that the oil filling port cover 8 integrates oil filling and air permeation functions;

[0027] Among them, the drain member one 6 and the drain member two 7 are both selected as drain bolts; and the drain bolts are matched with the leak-proof sealing gaskets 10 and the quick locking mechanism of the drain bolts themselves to ensure the convenience and sealing performance of the oil draining operation.

[0028] The drain component 6 is located on the side of the oil tank body 1, which facilitates daily maintenance and draining of oil, reduces the weight of the assembly, and makes it easier to move; while the drain component 7 is located at the bottom of the oil tank body 1, which is used to completely drain the hydraulic oil in the oil tank body 1 before changing the hydraulic oil.

[0029] In a preferred embodiment, as shown in the appendix Figure 1 As shown, a rubber gasket 9 is attached between the oil tank body 1 and the oil tank cover plate 4 to enhance the airtightness of the oil tank body 1 and prevent hydraulic oil leakage.

[0030] Among them, since the rubber pad 9 is placed between the oil tank body 1 and the oil tank cover plate 4, the elastic sealing properties of the rubber material are used to enhance the overall airtightness of the oil tank body 1 and effectively prevent hydraulic oil leakage.

[0031] Among them, several evenly distributed bolts can fix the rubber gasket 9 between the fuel tank body 1 and the fuel tank cover plate 4, so that the three are integrated and have good airtightness.

[0032] In a preferred embodiment, as shown in the appendix Figure 1 As shown, the rubber gasket 9 is made of an oil-resistant and high-temperature-resistant material; for example, the material of the rubber gasket 9 is selected as nitrile rubber or fluororubber; thereby ensuring that the rubber gasket 9 maintains good sealing performance during long-term use.

[0033] In a preferred embodiment, as shown in the appendix Figure 1 As shown in the attached document Figure 1 As shown, both the first oil drain component 6 and the second oil drain component 7 are sealed to the bottom of the oil tank body 1 through the leak-proof sealing gasket 10.
