Embodiment Construction
[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments:
[0031] like Figure 1-5 As shown, a high ground clearance windrower provided by the present invention includes a cab 1, a frame 2, a rear axle mounting frame 3, a frame guard 4, a rear axle 5, and an engine 19. The cab 1, the engine The frame guards 4 are all located above the frame 2, and the rear axle mounting frame 3 is installed under the frame 2. The high clearance windrower also includes a walking and steering actuator, and the walking and steering perform The mechanism includes a servo motor 6, a front wheel 11, a rear wheel 13, a walking drive system, a rear wheel steering system, and a front wheel auxiliary steering system. The rear axle 5 connects the central shafts of the two rear wheels 13, and the walking drive The system is used to drive the rotation of the front wheel 11, including a dual variable pump 20 and a front w...

The invention provides a high ground clearance windrower, which is reasonably designed, matched with a travel drive system for front-wheel drive, a rear-wheel steering system for active rear-wheel steering, and a front-wheel auxiliary steering system. The speed matches the corners of the left and right rear wheels. The front wheel drive adopts hydraulic transmission with two pumps and two motors, and the two front wheels are controlled separately. The problem of high resistance and difficult passive differential speed has better walking and steering performance in the field with poor working environment. It also provides a control method for controlling the high ground clearance windrower of the present invention, which solves the problem of high ground clearance windrower in sticky The problem of efficient walking and steering under wet soil conditions is very practical and has broad application prospects.
Description
technical field [0001] The invention relates to the 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 staged harvesting of some high-stem crops (such as rapeseed), large-scale and efficient central row windrowers are urgently needed. The existing high ground clearance windrowing equipment steering forms are mainly two-wheel steering, generally there are two types, one is that the front wheel realizes the differential speed through the gearbox, and the rear wheel is adjusted by the hydraulic rod telescopically; the other is that the front wheel is driven by a hydraulic motor, Different flow distribution of the two motors realizes differential speed, and the rear wheel is a universal wheel to follow the movement of the front wheel. These two forms have relatively simple structures, and the steering effect is good in flat and ...
