Seeding rotation power transmission and cut-off converter of traction type seeder

Abstract

A seeding rotation power transmission and cut-off converter of a pull-type seeder belongs to agricultural machinery. A hexagonal shaft and a cylindrical shaft are sequentially and fixedly arranged on a power input inner hexagonal sleeve, a power transmission locking groove and a power cut-off locking groove are formed in the cylindrical shaft, an outer shoulder-shaped power output inner hexagonal pipe shaft with a through hole and a clamping spring sleeves the hexagonal shaft and the cylindrical shaft, a steel ball is installed in the through hole and the power transmission locking groove or the power cut-off locking groove, a sliding sleeve with an annular boss sleeves the outer shoulder-shaped power output inner hexagonal pipe shaft, the sliding sleeve is in contact fit with a clamping spring, and a pressure spring is assembled at the position between the sliding sleeve and the outer shoulder-shaped power output inner hexagonal pipe shaft. The seeder is reasonable and compact in structure, small in appearance size, capable of being conveniently configured and mounted on a machine tool, simple and rapid in conversion operation, high in conversion efficiency, capable of being used for rotating power transmission and cutting of various mechanical devices, wide in application range and high in adaptability.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to an operation assembly that can be assembled on various traction-type seeding implements for transmitting or cutting off the rotating power for sowing. Background technique [0002] When performing sowing operations, the traction seeder uses the rotational power generated by the contact friction resistance between the ground wheel of the implement and the ground soil to drive the shaft of the seed meter to rotate through the chain transmission system to complete the sowing operation. When traction seeding equipment is transported, it is necessary to cut off the power transmission between the equipment ground wheel and the seed meter shaft. The traditional method is to manually remove the transmission chain, which is laborious, inefficient, and easy to remove. Problems causing chain damage. In order to solve the problems existing in the above-mentioned traditional methods, an end fac...

Problems solved by technology

When traction seeding equipment is transported, it is necessary to cut off the power transmission between the equipment ground wheel and the seed meter shaft. The traditional method is to manually remove the transmission chain, which is laborious, inefficient, and easy to remove. Problems causing chain damage

In order to solve the problems existing in the above-mentioned traditional methods, an end face jaw clutch has been installed on the shaft of the seed meter, and power transmission or power cutoff can be realized through the clutch of the end face jaw clutch, but the structure is relatively complicated and the external structure size is large , It is difficult to assemble on the machine tool and other problems need to be solved
