Wheel-type hydrostatic driving intelligent universal chassis of grain harvesting machine

Abstract

The invention relates to the technical field of agricultural machinery and provides a wheel-type hydrostatic driving intelligent universal chassis, capable of quickly satisfying harvesting requirements of different grains, of a grain harvesting machine. The universal chassis comprises a rack, a front driving wheel, a rear driving steering wheel, a front vehicle frame, a rear vehicle frame, an adjustable support, a power module, a front driving hydraulic closing-type system, a rear drying type hydraulic system, a working unit power module (hydraulic multi-way valves), an electro-hydraulic steering system, a driving cab, an integrated control panel and a CAN bus monitoring panel. According to a traveling system, front wheels are driven by the front driving hydraulic closing-type system, and rear wheels are subjected to open type driving under the control of an electro-hydraulic proportional directional valve; and front driving or four-wheel driving can be switched by a controller; the steering system adopts an electro-hydraulic steering unit which can conduct manual steering, remote-controlled steering, automatic steering and bus controlling; the electro-hydraulic multi-way valve module can meet the requirements of working units of harvesting machines of different types; and the bus monitoring controller panel and the integrated control panel in the driving cab can complete monitoring and controlling over all the systems and all the working units.

Description

technical field [0001] The invention provides a universal chassis of a wheeled full-hydraulic drive intelligent harvester capable of rapidly forming different grain harvesting requirements, which belongs to the technical field of agricultural machinery. Background technique [0002] With the large-scale popularization of agricultural mechanization, the traditional grain harvester chassis can no longer meet the actual needs in terms of basic performance and versatility. The production method of a single harvester chassis with a working device greatly increases the production of enterprises Manufacturing cost and purchase burden for farmers. In addition, there are still many problems in the design of the self-propelled harvester chassis, such as large turning radius, small ground clearance, inappropriate front and rear wheel speed ratio, unreasonable layout of components on the chassis, high failure rate, and high handling strength , low degree of intelligence, etc., these al...

[0002] With the large-scale popularization of agricultural mechanization, the traditional grain harvester chassis can no longer meet the actual needs in terms of basic performance and versatility. The production method of a single harvester chassis with a working device greatly increases the production of enterprises Manufacturing costs and purchase burden on farmers

In addition, there are still many problems in the design of the self-propelled harvester chassis, such as large turning radius, small ground clearance, inappropriate front and rear wheel speed ratio, unreasonable layout of components on the chassis, high failure rate, and high handling strength , low degree of intelligence, etc., these all restrict the improvement of the product quality of grain harvesters
