An engine oil pump hole and a filter mounting hole are formed in a machine body of the vertical single-cylinder diesel engine, a first hole is formed below the engine oil pump hole, and the oil suction disc joint is mounted in the first hole.

The oil suction disc shell is provided with an upward extending flange at the insertion opening at the top.

The oil suction disc shell is provided with a step at the bottom, and the filter screen is in lap joint with the step.

Two or more stamping fixing grooves are formed in the vertical wall of the step in an inward stamping mode and are used for preventing the filter screen from being separated from the oil suction disc shell.

The oil suction pipe is connected with the oil suction disc joint through a joint end, and the joint end is perpendicular to the oil suction end.

The utility model adopts the technical proposal to achieve the following beneficial effects:

1) the oil suction pipe extends into the oil suction disc shell, the distance from the oil suction end to the bottom surface of the oil suction disc shell is 9mm, the filter screen is arranged at a position 5mm away from the bottom surface of the oil suction disc shell, so that the oil suction pipe does not protrude out of the bottom plane of the oil suction disc shell, the end of the oil suction pipe is provided with a wedge surface with an oblique angle of 45 degrees, and the phenomenon that oil is sucked by an oil suction disc due to the fact that the end of the oil suction pipe is attached to the bottom of an engine when the oil suction disc assembly is installed out of level with the bottom of the engine can be prevented.

2) According to the utility model, the filter screen is arranged in the oil absorption disc, so that engine oil can filter impurities and then enter the filter, the service life of the filter is prolonged, and the oil path is cleaner. Thereby the oil absorption plate has the functions of oil absorption, filtration and the like. The filter screen has simple installation structure and low cost, and is worth popularizing.
