Universal connection suspension assembly for tractor operation machinery

Abstract

The invention relates to a universal connection suspension assembly for tractor operation machinery, which comprises a gap bridge assembly, wherein the gap bridge assembly is provided with a gap bridge fork, one end of the gap bridge fork is connected with a first cross bearing, the first cross bearing is connected with a connection joint fork, the connection joint fork is connected with a six-key connection shaft, the end, away from the six-key connecting shaft, of the gap bridge fork is connected with a second cross bearing, the second cross bearing is connected with a spline fork, the spline fork is connected with a two-way connecting shaft, the two-way connecting shaft is sleeved with a bearing, the bearing is connected with a first shaft sleeve, the first shaft sleeve is fixedly connected with a first assembly, the six-key connecting shaft is provided with a bearing, the bearing is connected with a second shaft sleeve, the second shaft sleeve is fixedly connected with a second assembly, and a second transverse plate and a first transverse plate are arranged in an inserted mode. According to the universal connection suspension assembly, the working reliability of a tractor and an agricultural implement is improved, large torque can be obtained, and repair and maintenance are convenient.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a universal connection suspension assembly of a tractor working machine. Background technique [0002] Judging from the current development of agricultural machinery, agricultural machinery is constantly being updated, and the connection between tractors and agricultural machinery is also constantly improving. From the earliest time, the mechanism connecting tractors and agricultural implements was a simple lifting mechanism, and later developed into a three-point suspension mechanism, followed by a hydraulic lifter, developed into a hydraulic suspension system and semi-suspension, and now the electronically controlled hydraulic suspension system. The way tractors are connected to agricultural implements is constantly changing. But one thing remains constant, that is, the suspension system is the universal connection between the tractor and the agricul...

AI Technical Summary

Problems solved by technology

[0003] The machine on the agricultural tractor needs to be used in conjunction with the suspension device when it is working. At present, the suspension device on the agricultural tractor generally drives the rotary tiller up and down through the upper and lower rods. The upper and lower rods are generally connected with the upper and lower shafts on the bracket Rotation connection, when the tractor is moving, the upper and lower rods, the lower rods and the upper and lower shafts on the bracket swing to a large extent, resulting in serious wear and tear on the upper and lower rods and the upper and lower shafts, and the service life is short

Moreover, since the length of the upper tie rod cannot be adjusted, it has limitations on the angle adjustment of the rotary tiller
