Description
Technical field
The invention belongs to combine harvester technical field of research, and in particular to one kind cutting vertical stream threshing separation transmission system two
Shelves variable speed drive.
Background technology
Since combined harvester has multiple workpieces to be completed at the same time different types of work in harvesting crops, and it is every
The demand of the operating power of kind workpiece is different, so transmission device becomes the important component of combined harvester.
The Stability and dependability of transmission device directly influences the transaction capabilities and service life of combine harvester.It is existing at present complete
Feeding rice combine is cut there are mainly two types of the kinds of drive of vertical flow pattern twin-roll threshing, and one is unilateral chain drives, pass
Dynamic structure is arranged in the same side, and another kind is to use both sides power transmission.The transfer mode of two kinds of power, which all exists, transmits road
The problem of path length, transmission efficiency is low, transmission stability and poor reliability, and chaindriven mode is all used, can exist larger
Noise and vibration, running stability are poor.
Chinese patent application CN106612997A discloses one kind and cuts in vertical stream installed threshing separator dynamic transfer system, moves
Power passes to jackshaft from engine, then transfers power to preposition lateral cut flow roller left end sprocket wheel, and power cuts stream by horizontal again
Drum shaft right end is directly delivered to the transmission case of right end, and transmission case will be transmitted to longitudinal axial flow roller after power commutation speed change by chain drive
Axis front end.This kind of drive needs multistage chain drive, and there are larger noise and vibration, running stability is poor.
One kind disclosed in Chinese patent application CN106717593A is cut in vertical stream installed threshing separator, and engine passes through biography
The power from power input terminal input that dynamic system passes over drives transmission shaft rotation by sprocket wheel, and transfers power to tooth
Transmission case is taken turns, while gear imparts power to longitudinal axial flow roller axis, power is transmitted to by sprocket wheel, chain by transmission shaft
Power is transmitted to the sprocket wheel on cut flow roller right end and realizes drive cut flow roller rotation by wheel chain, and there are larger noises for chain drive
And vibration lacks overload protection, and the installation site of transmission case and transmission case and longitudinal axis flow roll to the bad adaptability of crop
Assembly between cylinder axis is difficult installation.
It is dynamic that kind full-feeding combine harvesters disclosed in Chinese patent application CN102860184A cut vertical flow pattern threshing cylinder
Force transmission mechanism, with output end branch in horizontal threshing cylinder both sides, output end connects the power intake of horizontal threshing cylinder
Bevel gear housing, then power is transferred to machine tail portion through transmission shaft, then longitudinal axial flow roller main shaft is driven through driving member again
Rear portion makes its rotation.This long power attenuation of kind of drive transmission shaft increases, and transfer reliability is poor.
In short, existing cut there are mainly two types of the vertical stream combined harvester kinds of drive：One is the transmission of unilateral chain, transmissions
Structure is arranged in the left side of cropper；Another kind is to use both sides power transmission, and there are transmission paths for both kinds of drive
Long, drive mechanism is complicated, the low problem of transmission efficiency, and since chain is longer, and chain trembling is violent in operation process, not only
Accelerating abrasion makes reliability reduce, and also will produce larger vibration and noise.
For the mode for cutting vertical stream combined harvester transmission front end input of less appearance at present in the market, i.e., power is by sending out
Motivation is transmitted on the left of body by a transmission shaft, then transfers power to horizontal cut flow roller by chain drive, horizontal to cut
Stream roller transfers power to transmission case again, and last transmission case transfers power to longitudinal axial flow roller, and transmission case is located at and cuts stream
Roller and longitudinal axial flow roller are direct, and longitudinal axial flow roller axis is directly the vertical output shaft of transmission case.This kind of drive exists more
Grade chain drive, shortage overload protection, and cut flow roller axis are that the vertical output shaft of transmission case is brought to the installation of cropper
Inconvenience, and only there are one gears for transmission, define the rotating speed of threshing cylinder.
In addition, the installed threshing separator of rice combine in the market is bad to the applicability of crop, it cannot basis
The moisture content of crop, adjusting of the Grass Valley than making threshing cylinder rotating speed with threshings influence factors such as unit area crop yields, especially
It is which not only adds the operation effects that regulating time when operation also reduces cropper in oily (wheat) the crop rotation area of China rice
Rate.It is simple to be badly in need of a kind of energy drive system structure currently on the market, small power consumption, transmission efficiency height, and crop is adapted to, have
The installed threshing separator of stronger versatility.
Invention content
