Further, the cover plate and the box body are openable and are connected and sealed through bolts.

Furthermore, an oil drain pipe is arranged on the bottom surface of the box body, and an oil drain seat is arranged on the oil drain pipe.

Furthermore, the bottom end of the oil suction pipe is a diagonal plane, and the tip of the oil suction pipe is flush with the plane.

Further, the axis of the oil suction pipe is coincident with the axis of the oil drain pipe.

Further, a rubber pipe is connected with the oil injection port in the oil injection pipeline.

Furthermore, an oil level sensor connecting port is further arranged on the cover plate.

The utility model has the advantages that: the diesel tank can be used for periodically cleaning the interior of the tank body by connecting the cover plate and the tank body into a split type; the oil return pipe is arranged in an L shape, and the tail end of the oil return pipe is far away from the oil suction pipe, so that the oil return can be sucked by the oil suction pipe after being cooled; the bottom surface of the box body is provided with a plane and an inclined plane, so that the oil suction efficiency of the oil suction pipe is higher; the rubber tube is arranged on the oil injection pipeline, so that oil injection is facilitated.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

As shown in fig. 1 and 4, the diesel tank comprises a tank body 1, wherein a cover plate 2 is arranged on the tank body 1, and the cover plate 2 and the tank body 1 are openable and connected through bolts. For better sealing, a clip-shaped rubber plate is arranged between the cover plate 2 and the flange of the upper opening of the box body 1. The diesel tank sets up openable mode, can conveniently carry out regularly clearance to 1 insides of box.

As shown in fig. 2, an oil filling port 3 and an oil suction port 4 are provided on the cover plate 2, an oil filling pipeline 31 is connected to the outside of the oil filling port 3, and a rubber pipe is connected to the oil filling port 3 in the oil filling pipeline 31, so as to facilitate oil filling.

The oil suction port 4 is connected with an oil suction pipe 41 arranged in the box body 1; the bottom surface of the box body 1 is provided with a plane 6 and an inclined plane 7 which are integrally arranged. As shown in fig. 3, the bottom end of the oil suction pipe 41 is a chamfered surface, the tip portion of the oil suction pipe 41 is flush with the plane 6, the axis of the oil suction pipe 41 coincides with the axis of the oil drain pipe 8, and the tip portion of the lower portion of the oil suction pipe 41 is located at the upper opening of the oil drain pipe 8.
