Steering engagement and disengagement driving mechanism of combine-harvester

Abstract

The invention belongs to the technical field of agricultural equipment, and provides a steering engagement and disengagement driving mechanism of a combine-harvester. The steering engagement and disengagement driving mechanism comprises an engagement and disengagement steering shaft, a steering main gear assembly, a steering gear assembly, a steering shifting fork assembly and a braking assembly, and a shaft seal assembly is arranged at the outer side end of the braking assembly and used for keeping the rotating position of the engagement and disengagement steering shaft and the fixed position of the braking assembly. The steering engagement and disengagement driving mechanism has the advantages that by means of the steering main gear and steering gear structure of the steering engagement and disengagement driving mechanism, good stability is achieved, the mounting position is precise and reliable, the clearance arrangement is reasonable, and walking and steering of the combine-harvester can be fast and stably achieved; according to the braking assembly, a plurality of alternately combined separation plates and friction plates cooperate, braking stability is good, the running speed of the combine-harvester on a smooth-riding surface is increased, the adaptability of the combine-harvester to complex field blocks is improved, and the cross-regional operation performance of the combine-harvester is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural equipment and relates to a combine harvester, in particular to a steering clutch driving mechanism of the combine harvester. Background technique [0002] Agricultural machinery refers to various machinery used in crop planting and animal husbandry production, as well as in the primary processing and handling of agricultural and animal products. Agricultural machinery also includes crop harvesting machinery, agricultural transport machinery, etc. At present, driven by factors such as national policy guidance and the transfer of rural labor force, the speed of domestic land transfer has accelerated, the area of ​​a single plot has increased, the roads for machine farming have become wider, and the yield per mu of crops has continued to increase. Users have higher and higher requirements on the working efficiency of combine harvesters. On the other hand, users have higher and higher requireme...

Problems solved by technology

On the other hand, users have higher and higher requirements for the return on investment of combine harvesters, and the harvest of single-season crops can no longer meet the user's income requirements

[0003] The walking power output mechanism of the combine harvester here is mainly used to realize the walking, braking and steering of the whole combine harvester by driving the crawler belt, and the power input of the walking power output mechanism mainly depends on the steering clutch drive mechanism. The steering clutch driving mechanism in the technology is not only complicated in structure, but also causes serious loss to the internal friction plate, greatly reducing the service life. When turning, there is a braking power loss on the inner track, and the outer side needs more power from the engine. Once the load increases, the single Increased side track resistance will cause the engine to stall, resulting in problems such as smooth roads, cross-area operations, and difficulty in steering. At the same time, it is impossible to realize the arc walking direction of the corners when turning, resulting in the inability to harvest crops at the corners.
