As preferable: and the outer sides of the support bearings in the columnar protruding parts are all provided with oil seal structures. By adopting the scheme, the sealing performance of the lubricating oil in the body can be effectively ensured, and oil leakage is prevented.

As preferable: and a circlip for holes is arranged between the oil seal structure and the adjacent support bearing.

As preferable: the body is in a cone shape with two symmetrical sides, the middle part of the front side of the body is provided with a front nose structure which is bent and extends downwards, and the lower end of the front nose structure is lower than or flush with the bottom cover plate. By adopting the scheme, the device can play a certain protection role on the body, and can damage the hard object which is blocked when meeting the front part in advance, so that the hard object is separated towards two sides, and the damage to the body is avoided.

Compared with the prior art, the utility model has the beneficial technical effects that:

the structure of the output shaft mounting structure of the cultivator is mainly optimized, the traditional end cover style is canceled, the left end cover, the right end cover and the box body are integrally manufactured, oil leakage is prevented, machining efficiency and assembly efficiency are improved, the assembly of the internal structure can be completed rapidly through the mounting window at the bottom, and meanwhile, later observation, maintenance, replacement and the like are facilitated.
