Mechanical cultivator ground wheel drive power clutch mechanism

Abstract

The invention discloses a mechanical cultivator ground wheel drive power clutch mechanism, and belongs to agricultural machinery. A pressure spring, driving interlocking teeth, follow-up interlocking teeth and a third sprocket sequentially sleeve a first driving shaft, the third sprocket and the follow-up interlocking teeth are integrated, the driving interlocking teeth are radially and circumferentially positioned and assembled in an axially movable manner on the first driving shaft, the follow-up interlocking teeth, the third sprocket and the first driving shaft are axially and radially positioned and circumferentially matched in a rotatable manner, the third sprocket is welded with a cultivating and weeding tooth roller sequentially through a second chain, a fourth sprocket, a second driving shaft, a fifth sprocket, a third chain and a sixth sprocket, a driving and driven interlocking teeth separating mechanism comprises a bar frame, a swing bar, a bidirectional hydraulic cylinder, a fork holder and a cone plate separating fork, and the cone plate separating fork is inserted among the driving interlocking teeth and the follow-up interlocking teeth in a matched manner. Implement ground wheel power is conveniently and rapidly transferred, communicated or cut off, and the mechanical cultivator ground wheel drive power clutch mechanism has the advantages of novel and reasonable structure, reliability in use and low operation labor intensity.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a mechanical intertillage and weeding implement that can be driven by ground wheels and external power from a tractor. Background technique [0002] In order to expand the operation adaptability of mechanical intertillage and weeding operation tools, ensure and improve the intertillage and weeding operation effect on different crops and under different natural conditions, a kind of intertillage and weeding teeth can be driven by the weeder with its own ground wheel and the external power of the tractor. The mechanical cultivator and weeder with roller rotation has been successfully developed by the applicant of this patent, and has been industrialized, and has been applied in production operations, and has achieved good technical results. However, it has been found in production practice that when the two driving forces interact When switching, it is necessary to disassemble or inst...

[0002] In order to expand the operation adaptability of mechanical intertillage and weeding operation tools, ensure and improve the intertillage and weeding operation effect on different crops and under different natural conditions, a kind of intertillage and weeding teeth can be driven by the weeder with its own ground wheel and the external power of the tractor. The mechanical cultivator and weeder with roller rotation has been successfully developed by the applicant of this patent, and has been industrialized, and has been applied in production operations, and has achieved good technical results. However, it has been found in production practice that when the two driving forces interact When switching, it is necessary to disassemble or install the transmission chain or transmission sprocket and other components in the ground wheel power transmission system of the implement to complete the cutting or connection of the driving power of the ground wheel. The operation is complicated and cumbersome, the work efficiency is low, and the labor intensity is high.
