Abstract
The present invention discloses a kind of power driven transmission device for full feeding rice and wheat combine. The transmission device includes one power driven mechanism, one speed change gear box, and a step-less speed variator in between. There is also a step-less speed variator between the power driven mechanism and the walking gear box for realizing step-less speed variation of the gear box, expanding speed varying range, reducing impact force, raising transmission reliability and prolonging service life. Inside the speed consists of gear box, there are three-speed gear and gear shift mechanism, and this makes it possible for selecting proper operation shift and step-less speed varying mechanism according to harvested crop and field conditions.
Description
Technical field
The present invention relates to the power-actuated transmission device of a kind of full feeding rice wheat combine.
Background technology
The present power-actuated transmission device of full feeding rice wheat harvester is made up of mechanical gear shift mechanism and tractor walking change gear box, engine was realized step speed change by mechanical gear shift mechanism controls walking gearbox when grain header was in the harvesting state, but this transmission device has following defective: the walking of (1) grain header can only realize step speed change, the scope of speed change is little, and impulsive force is big during speed change, poor reliability, the life-span of using is short, (2) operating mechanism more complicated, use inconvenience, and effort is very dumb during operation.
Summary of the invention
The invention provides the power-actuated transmission device of a kind of full feeding rice wheat combine, it can realize the grain header infinitely variable speeds in when walking, and slewing range is big, and the impulsive force during speed change is little, can increase the service life.
The present invention has adopted following technical scheme: the power-actuated transmission device of a kind of full feeding rice wheat combine, it comprises Power Drive Unit and change gear box, is provided with buncher between the input of described Power Drive Unit and change gear box.
Described buncher is set to hydraulic continuously variable transmission, it comprises pump housing and hydraulic oil container, be provided with variable pump in the pump housing, gear pump, oil rectifier, high-pressure safety valve I, high-pressure safety valve II, two-way hydraulic motor, the makeup oil safety valve, described variable pump is connected with Power Drive Unit, hydraulic motor output shaft is connected with the input of change gear box, the oil-in of described hydraulic oil container successively with oily coarse cleaner, gear pump is connected with oil rectifier, be divided into three oil circuits from oil rectifier, article one, be oil rectifier successively with high-pressure safety valve I, two-way hydraulic motor forms the forward oil circuit, another be oil rectifier again successively with high-pressure safety valve II, variable pump and two-way hydraulic motor form reverse oil circuit, also have one be oil rectifier successively with the makeup oil safety valve, the liquid oil cooler links to each other with hydraulic oil container.
Be provided with third gear in the casing of described change gear box, third gear is enclosed within respectively on the driving shaft, also is provided with shifter on casing, and the selector fork in shifter and the speed-changing gear box is connected.
After having adopted above technical scheme, the present invention is provided with buncher between Power Drive Unit and change gear box, buncher adopts hydraulic continuously variable transmission, it can realize the infinitely variable speeds of change gear box by the control oil mass, enlarge slewing range, and impulsive force reduces, and the reliability when having improved transmission has greatly prolonged service life.In speed-changing gear box, be provided with third gear and shifter, can select suitable gear to handle stepless speed changing mechanism according to the crop and the field piece condition of harvesting like this.
