Description
Technical field
The utility model relates to the driving arrangement of grain header, refers more particularly to a kind of grain header trailing wheel fluid pressure drive device.
Background technology
At present, agricultural grain header does not generally all have rear wheel drive, often because be short of power and cause gathering in the crops weak effect, and particularly when the harvesting paddy rice, grain header even can't work.Even there is on the grain header trailing wheel transmission of installation shaft-driven, also asynchronously occurs off-axis easily, beat the tooth phenomenon, the fault rate height because of front and back wheel drives.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of and can makes it to be fit to the results of various crops for grain header provides enough driving forces, and can guarantee that the grain header front and back wheel drives synchronously the grain header trailing wheel fluid pressure drive device that fault rate is low.
The technical solution of the utility model is such, and grain header trailing wheel fluid pressure drive device comprises hydraulic oil pump, hydraulic distributing valve, hydraulic control lever, pressure limiting valve, hydraulic oil container, oil return pipe, petroleum pipeline, hydraulic motor, hydraulic motor main oil pipe, hydraulic motor oil return pipe, power transmission shaft, difference device, fuel feed pump and pressure limiting valve drain mast;
Described hydraulic oil pump is housed on the locomotive engine, and hydraulic oil pump is connected with the power output of locomotive engine by belt; Described fuel feed pump is equipped with in the bottom of described hydraulic oil pump, and the other end of fuel feed pump is connected with described hydraulic oil container; Described oil return pipe is housed on the described hydraulic oil container, and the other end of oil return pipe is connected with described hydraulic distributing valve; Described petroleum pipeline is housed on the described hydraulic oil pump, and the other end of petroleum pipeline is connected with described hydraulic distributing valve, and described pressure limiting valve is housed on petroleum pipeline; Described pressure limiting valve drain mast also is housed on the described pressure limiting valve, and the other end of pressure limiting valve drain mast is connected with described oil return pipe; A pair of described hydraulic motor main oil pipe is equipped with in the bottom of described hydraulic distributing valve, and the other end of hydraulic motor main oil pipe is connected with described hydraulic motor; Described hydraulic control lever also is housed on the described hydraulic distributing valve; The hydraulic motor oil return pipe also is housed on the described hydraulic motor, and the other end of hydraulic motor oil return pipe is connected with described hydraulic oil container; Described power transmission shaft is housed on the described hydraulic motor, and the above difference device of the other end of power transmission shaft and trailing wheel main shaft joins.
Characteristics of the present utility model are: simple in structure, reasonable in design, can provide enough driving forces for grain header, and make it to be fit to the results of various crops, and can guarantee that the grain header front and back wheel drives synchronously, fault rate is low.Can be fit to installing and using of all kinds of grain headers.
