Description
Technical field
The present invention relates to a kind of steering mechanism, more specifically to a kind of steering mechanism of wheeled cane harvester.
Background technique
China is cane planting big country, and for the harvesting sugarcane mode in China still mainly based on artificial, use is most former at present
The mode of beginning is cut down, is shipped, whole process large labor intensity, low efficiency.With the fast development of China's economy in recent years, manually
Labour cost is continuously improved, so that sugarcane industrial profit continues to decline, cane planting is caused to reduce year by year.Therefore, harvesting sugarcane
It has excessively been imperative to professed machine that mode, which has manually,.
Currently, there are two main classes for sugar-cane cutting machine: whole stalk type cane harvesting machine and cutting type sugar-cane cutting machine.No matter belong to
That, accounts for the overwhelming majority using the sugar-cane cutting machine of running on wheels mode, and wheeled cane harvester is all using all-hydraulic dynamic
Power, deflection front-wheel steer.
Due to gathering in the need of work of sugarcane, the service aisle of sugar-cane cutting machine must be in central frame beam along longitudinal direction of car cloth
It sets.As shown in Fig. 1 Fig. 2, preceding service aisle includes that the first indentation roller 8, second is pressed into roller 7, ceding of Taiwan box assembly 5 and left and right sides vehicle
Frame plate.First indentation roller 8 and the second indentation roller 7 can be driven by hydraulic motor around respective central axis and be rotated, the first pressure
The height for entering roller 8 is adjustable, and the height of the second indentation roller 7 is fixed.There are two the ceding of Taiwan casees of cutterhead to be fixed on vehicle frame for band, hydraulic horse
Up to carrying out breaking apart by chopping 6 root of sugarcane by the rotation of ceding of Taiwan case variable velocity zone movable knife disc 51 and work the sugar cane lifting broken apart by chopping and backward
Channel conveying.Therefore, two front-wheels must use freestanding suspension form (case is MacPherson strut in figure), hang
It is high that the height of frame oil cylinder adjustable must make cutterhead height adapt to a variety of different ridges of sugarcane field.
Currently, the sugar-cane cutting machine manufacturer of lot of domestic and foreign can not all solve limited space to wheeled cane harvester
Turning to bring influences, and the scheme of use is: being arranged in the big chamber oil circuit of vehicle frame left side steering cylinder and is arranged on the right of vehicle frame
The small chamber oil circuit of steering cylinder is (turning to oil circuit A) in parallel, is arranged in the small chamber oil circuit of vehicle frame left side steering cylinder and is arranged in vehicle
The big chamber oil circuit of steering cylinder is in parallel on the right of frame (turning to oil circuit B).Two mutually independent steering front wheels 3 are each by an oil
Cylinder is fixed or turned to, and causes the relative position of deflecting roller uncontrollable: when steering, all tire of vehicle can not form unified turn
To center, tire breaks away seriously, and it is uncontrollable to increase steering resistence, aggravation tire wear, steering angle；Straight line walking ability is poor,
Enhance the labor intensity of driver when operation, and just needs to manually adjust the toe-in of steering front wheel at regular intervals, it is time-consuming and laborious
Also take tire.
