Ground-clearance-adjustable tractor transmission system

Abstract

The invention relates to a ground-clearance-adjustable tractor transmission system which comprises a casing and an upper driving haft shaft which is arranged in the casing, wherein the upper driving half shaft is provided with a first output end which extends out of the casing. The ground-clearance-adjustable tractor transmission system is characterized in that a lower driving half shaft which is connected with the upper driving half shaft through a gear device is also arranged in the casing; the lower driving half shaft is provided with a second output end which extends out of a sleeve casing; and the lower driving half shaft and the upper driving half shaft have the same rotating speed and rotating direction. According to the invention, the upper driving half shaft and the lower driving half shaft exist simultaneously so that double-shaft output is realized; a single tractor has two ground clearances of first plowing and inter-plowing simultaneously; not only the investment cost of equipment is saved, but also the utilization efficiency of the tractor is enhanced; and the lower driving half shaft is directly connected with the upper driving half shaft through the gear device and the two shafts form a whole, so that the output transmission force of the lower driving half shaft is ensured, and transmission is safer and more reliable.

Description

technical field [0001] The invention relates to a transmission system, in particular to a tractor transmission system with adjustable ground clearance. Background technique [0002] Usually, low-gap tractors are used for primary tillage operations. Because crops are in the growth stage, low-gap tractors are easy to damage crops in intertillage operations. At this time, they must be replaced by high-gap tractors. Therefore, farmers must be equipped with high-gap tractors when farming. The two types of tractors with different low ground clearances not only have low efficiency of single use, but also greatly increase the economic burden of farmers. [0003] In order to improve the versatility of the tractor, such a structure is disclosed in the prior art such as the Chinese utility model "Adjustable Ground Gap Tractor Steering Axle" whose patent number is ZL200920088593. Fittings, kingpin sleeve, steering arm, tie rod assembly, beam, bracket, pin shaft, trailing rod, steering ...

AI Technical Summary

Problems solved by technology

Therefore, the above-mentioned patent uses the longitudinal pull rod to push (or pull) the steering arms to drive the two wheels to rotate, and the steering knuckle joint is rotated 180 degrees for installation to achieve the adjustment of the high and low ground clearance of the tractor steering bridge. However, the above-mentioned The structure of the patent is relatively complicated, and the steering knuckle joint must be rotated 180 to install during adjustment, which is troublesome to operate and adjust; moreover, the steering knuckle joint and the main pin joint are fixed by positioning pins or screws, once the positioning pins or screws are worn out or failure, it will cause the steering knuckle joint and the kingpin joint to be unable to be reliably fixed, which will affect the safety and reliability of the entire equipment. Therefore, further improvement is needed
