Folded type paddy cultivator tooth embedding type clutch provided with anti-disengaging structure

Abstract

The invention discloses a folded type paddy cultivator tooth embedding type clutch provided with an anti-disengaging structure. The folded type paddy cultivator tooth embedding type clutch provided with the anti-disengaging structure is arranged on a folded type paddy cultivator; an output shaft of a central speed changing box is connected with an input shaft of an edge speed changing box in a first bearing pipe through the tooth embedding type clutch; the tooth embedding type clutch comprises a first half clutch body fixedly connected to the end portion of the output shaft of the central speed changing box in a sleeved manner, and a second half clutch body in sliding connection with the end portion of the input shaft of the edge speed changing box in a sleeved manner; and first teeth on the end face of the first half clutch body and second teeth on the end face of the second half clutch body are both trapezoidal teeth which become wider while being away from the end faces. According to the further improvement, the end, away from the second teeth, of the second half clutch body is provided with a second compression spring for pressing the second half clutch body to the first half clutch body in the axial direction. When the folded type paddy cultivator performs cultivation, it can be effectively guaranteed that the tooth embedding type clutch is free of disengagement, and normal use of the folded type paddy cultivator is guaranteed.

Description

technical field [0001] The invention relates to the technical field of farmland tillage machines, in particular to a clutch structure of a foldable paddy field tillage machine. Background technique [0002] With the development of agriculture, paddy field tillers are widely used in agricultural production. The paddy field tiller includes the frame, suspension assembly, tillage mechanism, and transmission system. The horizontal dimension of the frame is long, and it is very inconvenient to walk or transport. When encountering a narrow road, it is impossible to walk at all, which seriously affects the performance of the tiller. Use and promotion, therefore, people are now studying to improve the rack into a foldable structure. The frame includes a middle frame and side frames hinged on both sides of the middle frame through a first pin; in an unfolded state, the side frames are horizontally horizontal and perpendicular to the front and rear movement directions of the foldable...

AI Technical Summary

Problems solved by technology

The main defect of the jaw clutch of the existing foldable paddy field tillage machine is that when the foldable paddy field tillage machine is plowing, the first half clutch and the second half clutch of the jaw clutch may be disengaged, which affects the folding. Normal use of paddy tillage machine
