A drive shaft device for swing arm type agricultural machinery

Abstract

The invention discloses a transmission shaft device for swing arm type agricultural machinery, which comprises a frame body, mounting plates are fixedly connected to both sides of the frame body, fixing holes are arranged on the mounting plate, and a front end surface of the frame body is provided with A large ball head seat, and a ball head is arranged in the large ball head seat, a support rod is fixedly connected to the ball head, and a frame fixing plate is arranged at the front end of the support rod, and a telescopic shaft is connected to the frame fixing plate, And the telescopic shaft is provided with a spring, and one end of the telescopic shaft is fixedly connected with a small ball seat, and the other end of the support rod is fixedly connected with a ball head. The swing arm type transmission shaft device for agricultural machinery can facilitate all-round adjustment of the position of the swing arm of the transmission shaft, so that the applicability of the swing arm type transmission shaft device for agricultural machinery can be improved, and the torque of the output shaft can be easily adjusted. Therefore, the agricultural machinery can adjust the output torque according to the working conditions, and the structure stability of the transmission shaft device for the swing arm type agricultural machinery can be improved conveniently.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a transmission shaft device for swing arm type agricultural machinery. Background technique [0002] Swing arm agricultural machinery usually includes lawn mowers, rotary tillers, etc. The angle of the frame can be adjusted to obtain different working areas or to adapt to transportation, transfer and other working conditions. , the transmission shaft device needs to be able to ensure stable transmission of the driven mechanism, so as to ensure the stable operation of agricultural machinery. [0003] However, the swing arm adjustment direction of the existing swing arm type agricultural machinery transmission shaft device is single, and the driven mechanism can only move in a single direction, so that its applicability is poor, and the existing swing arm type agricultural machinery use transmission shaft device cannot Adjusting the torque of the output shaft makes ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a swing arm type transmission shaft device for agricultural machinery to solve the problem that the existing swing arm type transmission shaft device for agricultural machinery has a single swing arm adjustment direction and cannot adjust the torque of the output shaft in the above background technology. Adjustment and the problem of poor structural stability of the transmission shaft device
