Anti-jam wheel of agricultural sowing machine

Abstract

The invention discloses an anti-jam wheel of an agricultural sowing machine. The anti-jam wheel includes a rotation shaft and a wheel body; the rotation shaft is movably connected to the wheel body through a bearing; the bearing includes a bearing inner ring and a bearing outer ring; steel balls are evenly arranged between the bearing inner ring and the bearing outer ring; oil inlet holes are formed in the steel balls; second sponge blocks are added in inner cavities of the steel balls; the oil inlet holes communicate with the second sponge blocks; second oil injection holes are formed in the bearing inner ring; the second oil injection holes are connected to one end of an oil injection pipe, and the other end of the oil injection pipe communicates with a gap between the bearing outer ring and the bearing inner ring; a first protection cover is arranged on the left side of the bearing; a first oil injection hole is formed in the left side of the first protection cover; a first sponge block is added in an inner cavity of the first protection cover; and a second protection cover is arranged on the right side of the bearing. The anti-jam wheel is simple in structure, can effectively prevent the wheel from jam, and can ensure normal working.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an anti-seize wheel of an agricultural seeder. Background technique [0002] Since the founding of the People's Republic of China, especially since the implementation of reform and opening up, efforts have been made to strengthen the agricultural infrastructure and agricultural technology system, which has significantly improved the level of agricultural mechanization and the appropriate conditions for agricultural foundations such as farmland water conservancy, transportation, and communication. In particular, the rapid development of agricultural machinery has continuously improved the level of agricultural technology in our country. In the process of agricultural cultivation, the seeder is the most used agricultural machinery, and the environment in which the seeder is in use is very harsh. The erosion of rainwater and the attack of dust will seriously affect th...

Problems solved by technology

In the process of agricultural cultivation, the seeder is the most used agricultural machinery, and the environment in which the seeder is in use is very harsh. The erosion of rainwater and the attack of dust will seriously affect the service life of the seeder. Once the wheel bearings of the seeder get into the dust, they will rust, and the wheels will be stuck, which will seriously affect the normal work.
