AI Technical Summary

Technical Problem

The internal air pressure of the existing full-film machine is increased due to the oil sealing seal, and lubricating oil cannot be injected, resulting in the bearing being unable to lubricate and may burn out, affecting the normal operation of the transmission system.

Method used

Axial and radial holes are opened on both sides of the roller shaft, and a combination of a straight-through oil filling cup and pressure relief valve can realize the filling and gas discharge of lubricant oil to ensure the effective entry and use of lubricant oil.

Benefits of technology

It realizes easy filling of lubricant oil in the driven roller and gas discharge, extends service life, and reminds that the lubricant oil is appropriate to avoid the problem of overheating and burning of the bearing.

Abstract

The utility model belongs to the field of oil injection and pressure relief structures, and particularly relates to an oil injection and pressure relief structure for a driven carrier roller of a soil feeding chain of a full-film planter, which comprises a carrier roller shell, a bearing is arranged in the carrier roller shell, a carrier roller shaft is arranged in the bearing in a penetrating manner, and glands are mounted at two ends of the carrier roller shell through bolts. And the carrier roller shaft penetrates through the gland and is rotationally connected with the gland. The roller carrier shaft is provided with the holes in the two sides, the axial holes and the radial holes are formed in the two sides of the roller carrier shaft respectively and communicated, the axial holes in the two sides of the roller carrier shaft are not communicated, the axes of the two radial holes are distributed in a 90-degree mode, and the two sides of the roller carrier shaft are provided with the threaded installation holes of the straight-through type oil injection cup and the pressure release valve. And one end of the straight-through type oil injection cup and one end of the pressure release valve are arranged, so that grease and lubricating grease can be easily injected into the driven carrier roller more reliably, and the service life is prolonged.
