Problems solved by technology
Due to the complexity of the terrain in our country, the two-speed control cannot adapt to the hilly changes in the planting land. At the same time, the weeds and soil on the ground may entangle the walking wheels, resulting in a large drive power required for the working gear.

Embodiment Construction
[0011] As shown in the figure, a walking hydraulic control system of a sugarcane harvester includes two variable hydraulic pumps 1, two variable hydraulic motors 2, a flushing valve 3 and a shift valve 4, and the shift valve 4 is a two-position Three-way electromagnetic reversing valve. The walking hydraulic control system of the present invention is applied to the crawler walking sugarcane harvester. The crawler walking mechanism can effectively reduce the space of the chassis to prevent weeds and sugarcane leaves from falling and winding the wheel shaft. The southern region is often rainy and the surface is muddy, and the crawler walking is adaptable to the surface conditions. powerful. The hydraulic motor is installed at the center line of the traveling wheel, and drives the traveling wheel to drive the crawler to travel. The two variable hydraulic pumps 1 are respectively connected to the two variable hydraulic motors 2 through the flushing valve 3 to form a closed hydrau...

The invention relates to a traveling hydraulic control system for a cane harvester. The traveling hydraulic control system comprises two variable hydraulic pumps, two variable hydraulic motors, flush valves and a shift valve. The shift valve is a two-position three-way electromagnetic directional valve, the two variable hydraulic pumps are connected with the two variable hydraulic motors respectively to form a closed hydraulic loop, each variable hydraulic pump is provided with an auxiliary oil port, the auxiliary oil ports are connected with the two variable hydraulic pumps through the shift valve, and the two variable hydraulic pumps are connected to a pushrod hand lever in a driver room through flexible-shaft couplers respectively. Compared with a traditional open loop, the traveling hydraulic control system has the advantages that control valves are effectively reduced, structural arrangement of the system is facilitated, operations are facilitated for a driver, pipeline connection is reduced, and accordingly component faults and leakage in operation of hydraulic machinery are effectively reduced.
Description
technical field [0001] The invention relates to the technical field of sugarcane harvesting machinery, in particular to a walking hydraulic control system of a sugarcane harvester. Background technique [0002] The harvesting of sugarcane has special harvesting requirements, such as the requirement to remove the top cane tips during the harvesting process, and to peel off the outer cane leaves, and at the same time, in order not to lose the sugar, the skin of the sugarcane should not be damaged, etc., so it is a relatively cumbersome labor. . For a long time, due to the special requirements of sugarcane harvesting, my country has mostly adopted manual harvesting, which leads to a large amount of human labor, low efficiency and high cost. [0003] At present, my country's sugarcane is mostly planted in the south, with hilly terrain and ridge-divided planting, which is not suitable for foreign high-power sugarcane harvesters. Secondly, the ground conditions of the sugarcane ...
