Problems solved by technology

[0003] At present, the hydraulic steering system of the harvester is basically controlled by an independent operating handle. Each operating handle controls a separate hydraulic steering system. Each operating handle can only complete the function of turning left or right. The operation of this hydraulic steering system Complicated, prone to misoperation, reducing the driver's work efficiency

Abstract

The invention provides a hydraulic turning mechanism of a harvester. The hydraulic turning mechanism comprises a duplex variable pump, an operation handle and a gearbox driven by the operation handle to move front and back, and further comprising a movable platform mounted under the gearbox, and a moving mechanism connected with the gearbox. The gearbox can move on the movable platform via the moving mechanism; the operation handle can be connected with the gearbox via a driving connection mechanism; the gearbox is provided with a hydraulic oil control mechanism controlling flow directions of duplex variable hydraulic oil via front and back movements of the gearbox. The hydraulic turning mechanism of the harvester is simply structured and can be conveniently operated; a deficiency of single handle controlling one direction turn of a traditional harvester can be overcome, so work efficiency of drivers can be greatly improved and mis-operation of the driver can be reduced.

Description

technical field [0001] The invention relates to a harvester, in particular to a hydraulic steering mechanism for the harvester. Background technique [0002] Harvesters are widely used in the agricultural field. With the increasing power and weight of harvester vehicles and the continuous improvement of driving speed, people have higher and higher requirements for the steering performance of harvesters. [0003] At present, the hydraulic steering system of the harvester is basically controlled by an independent operating handle. Each operating handle controls a separate hydraulic steering system. Each operating handle can only complete the function of turning left or right. The operation of this hydraulic steering system Complicated, prone to misoperation, reducing the driver's work efficiency. Contents of the invention [0004] The purpose of the present invention is to provide a hydraulic direction changing mechanism for harvesters, which can change the hydraulic oil fl...
