High-ground-clearance swather and linear walking and turning control method thereof

Abstract

The present invention provides a high-ground-clearance swather which is reasonable in design, a walking driving system for front wheel driving, a rear wheel steering system for active steering of rear wheels and a front wheel auxiliary steering system are matched, the front wheel auxiliary steering system is in active differential matching with the rotating angles of the left rear wheel and the right rear wheel, two-pump and two-motor hydraulic transmission is adopted for front wheel driving, two front wheels are independently controlled. According to the high-ground-clearance swather, the slipping phenomenon caused by free differential speed of the left front wheel and the right front wheel is avoided, the problem that passive differential speed cannot be achieved easily due to the fact that the resistance of the driving wheels is large during turning is solved, and the high-ground-clearance cutter-rower has good walking and steering performance in a field with a poor working environment, and a control method for controlling the high-ground-clearance cutter-rower is further provided. The problems of efficient walking and steering of the high-ground-clearance windrower under the sticky and wet soil condition are solved, and the high-ground-clearance windrower is very practical and wide in application prospect.

Description

technical field [0001] The invention relates to a field of agricultural machinery, in particular to a windrower with high ground clearance and a control method. Background technique [0002] With the advancement of large-scale planting and the need for segmental harvesting of some high-stem crops (such as rapeseed), there is an urgent need for large-scale and efficient central windrowers. The steering form of existing high clearance windrowing equipment is mainly two-wheel steering, and there are generally two types. One is that the front wheels realize the differential speed through the gearbox, and the rear wheels adjust the rotation angle through the expansion and contraction of hydraulic rods; the other is that the front wheels are driven by hydraulic motors. Different flow distribution of the two motors realizes the differential speed, and the rear wheel is a universal wheel to follow the movement of the front wheel. The structure of these two forms is relatively simpl...
