[0002] Hydraulic oil tanks are usually installed on large mechanical equipment to provide fuel output for large mechanical equipment. When large equipment is in operation, hydraulic oil tanks are needed to provide energy output. For example, when an excavator is moving, a hydraulic press is needed to extract the fuel in the tank. The extracted fuel provides fuel output for the engine to provide power for the engine to operate.

[0003] When equipment such as excavators are moving and operating, when traveling on uphill sections, the fuel in the hydraulic oil tank tends to flow to one end of the tank. At this time, the oil extraction pipe is easily sucked empty, resulting in fuel output interruption and affecting the use of the oil pump. Therefore, a shock-absorbing hydraulic oil tank main body closed anti-empty device is proposed to solve the above-mentioned technical problems. Utility Model Content
