[0037] To better understand this utility model, the following is combined with... Figures 1 to 6The technical solution of this utility model is described in detail as follows: A first plate 211, a second plate 212, a third plate 213, and a fourth plate 214 are respectively provided inside the oil storage chamber 121 to enhance the overall robustness of the oil tank 12. Furthermore, a central hole 22 and a bottom hole 23 are formed on the first plate 211, the second plate 212, the third plate 213, and the fourth plate 214 to facilitate the flow of oil within the oil storage chamber 121 and to facilitate the extraction of liquid by the oil outlet pipe 123. A filter cartridge 1231 is provided at the end of the oil outlet pipe 123 for... The oil is filtered, and the multiple plates improve the overall structural integrity of the oil tank 12. Furthermore, the multiple baffles 21 provide good shock absorption and buffering, preventing the oil from impacting the inner wall of the oil storage chamber 121 during sloshing and causing damage. The corrosion-resistant coating applied to the first plate 211, second plate 212, third plate 213, and fourth plate 214 extends their service life. To prevent the oil outlet pipe 123 from scattering inside the oil storage chamber 121, the oil outlet pipe 123 is fastened to the inner wall of the oil storage chamber 121 by a locking block 124. To facilitate viewing the oil level inside the oil storage chamber 121, a groove 31 is provided on the outside of the oil tank 12. The groove 31 has a viewing window 32 and a scale 321. A movable cavity 331 is provided on the left side of the groove 31, and a spring strip 332 is installed inside the movable cavity 331. The spring strip 332 is used to push the baffle plate 34 to slide to the right within the groove 31, thus blocking the viewing window 32 and ensuring... The iron block 342 on the right side of the baffle 34 extends into the slot 311 and cooperates with the iron sheet. The baffle 34 covers the groove 31, which can improve the overall integrity of the fuel tank 12 and make its shape more beautiful. At the same time, it can protect the viewing window 32. When the staff needs to check the viewing window 32, the push block 341 pushes the baffle 34 to the left and squeezes the spring strip 332 to deform, so that the baffle 34 no longer blocks the viewing window 32. This makes it convenient for the staff to know the fuel level inside the fuel tank 12 at any time.
