[0030] like Figure 1 and Figure 2 As shown, the oil pan assembly includes an oil pan 1 and an outward bracket 2, and the outward bracket 2 is fixedly connected to the oil pan 1. The outward bracket 2 and the oil pan 1 together form at least two groups of front axle assembly positions to adapt to the assembly requirements of tractors with different wheelbases.

[0031] Specifically, the oil pan 1 includes a shell body 11, and a first inner recess 111 and a second inner recess 112 are provided on the lower side of the shell body 11. The first inner recess 111 is located at the front end of the shell body 11 to provide an installation space for the front axle assembly; the second inner recess 112 is used to avoid the transmission shaft; the arrangement of the first inner recess 111 and the second inner recess 112 reduces the height of the engine and makes the overall structure of the tractor compact.

[0032] The shell body 11 has a cavity inside, which is used to contain the engine oil. The opening end of the cavity is provided with a connecting flange surface 19, which is used to dock and seal with the engine body. The cavity can be divided into a first cavity portion 17 and a second cavity portion 18, wherein the second cavity portion 18 corresponds to the first inner recess 111, so its depth is less than the depth of the first cavity portion 17. The setting of the first inner recess 111 and the second inner recess 112 affects the capacity of the shell body 11 to a certain extent. In order to avoid the situation where the lubricating oil inside the engine is insufficient due to the reduced capacity of the shell body 11, two process bosses 16 are provided on the shell body 11, and reserved oil holes 161 are processed on the process bosses 16. When there is no need to expand the capacity of the oil pan 1, the reserved oil hole 161 is sealed with a sealing element 12, and the sealing element 12 can be a plug and a sealing ring; when the capacity of the shell body 11 cannot meet the engine lubricating oil requirement, the capacity of the shell body 11 needs to be increased. At this time, the sealing element 12 can be removed, and an oil pipe can be used to connect the cavity with an external oil storage container such as an oil pot, thereby expanding the capacity of the oil pan 1.

[0033] Furthermore, two reserved oil holes 161 are respectively arranged on the opposite side walls of the shell body 11, so that the lubricating oil flowing back into the cavity has a certain sedimentation time, which is conducive to the precipitation of impurities.

[0034] The first inner recess 111 is provided with at least a first connection boss 13 and a second connection boss 14. The first connection boss 13 is located in front of the second connection boss 14.
