Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery workpieces, in particular to an oil tank for agricultural machinery. Background Art

[0002] In the hydraulic system, the oil tank is an indispensable oil storage device. At present, most hydraulic systems use open oil tanks. Open oil tanks refer to the direct contact between the liquid level in the oil tank and the air. Its working principle is that when the oil level in the oil tank rises, the air above the oil level is discharged into the atmosphere through the vent; when the oil level drops, the atmosphere enters the oil tank through the vent. However, since the oil surface of the open oil tank is in direct contact with the gas mixed with dust and water vapor, it not only accelerates the oxidation and deterioration of the hydraulic oil, but also increases the failure rate caused by excessive oil contamination.

[0003] The existing fuel tanks on the market generally store oil directly. The oil outlet pipes on both sides are connected to other parts, and the oil circulation is achieved through the built-in pressure pump of the agricultural machinery. However, in actual use, the temperature of the oil will gradually increase during the circulation process, and the internal pressure of the closed environment will increase due to the heat, which is likely to cause a safety hazard of excessive internal pressure. For this reason, we have proposed a fuel tank for agricultural machinery. Utility Model Content
