According to the utility model, through the two mutually inverted step cones and the driving belt, an effect of different drive ratios between the drive shaft and the rotating shaft of the winnowing fan is achieved, so that the winnowing fan has various rotating speeds from slow to fast in a larger scope so as to adapt to the complex situations of crops harvesting, thereby guaranteeing the stability of a cleaning effect.
Description
Technical field
The utility model relates to a kind of combine, specifically relates to a kind of selection by winnowing fan drive of combine.
Background technology
Known grain header selection by winnowing blower fan generally by power through fixedly carrying out transmission after the speed change, in the harvesting operation, the rotating speed of blower fan is fixed.But the situation during crop harvesting differs, and cauline leaf content is many during crop harvesting sometimes, and the air quantity that needs to strengthen the selection by winnowing blower fan could guarantee to clean effect; Have to make composition granule light, like rape, the air quantity that needs to reduce the selection by winnowing blower fan just can prevent particle loss; Sometimes maturity differs during crop harvesting, like paddy rice, wheat, also need adjust the air quantity of selection by winnowing blower fan according to cleaning situation in the harvesting operation in good time, is only the effect of cleaning that reaches good.And the selection by winnowing blower fan in the known solution only can carry out work under fixed speed, is difficult to adapt to the harvesting selection by winnowing requirement of the complex situations and the Different Crop of crop harvesting, cleans the effect instability.
Summary of the invention
The utility model provides a kind of selection by winnowing fan speed regulation transmission device of combine, can carry out the transmission of multiple speed to the selection by winnowing blower fan, can adapt to the complex situations of crop harvesting, guarantees to clean the stable of effect.
The technical scheme that the utility model adopts is: a kind of selection by winnowing fan speed regulation transmission device of combine, comprise the selection by winnowing blower fan, and be separately installed with cone pulley one and cone pulley two in the rotating shaft of power transmission shaft and selection by winnowing blower fan; Cone pulley one is inverted with cone pulley two each other, and through the driving-belt transmission.
Described cone pulley one and cone pulley two are to have the drive of a plurality of radiuses of gyration from small to large.Mutual inverted cone pulley one and cone pulley two are installed respectively in the rotating shaft of power transmission shaft and selection by winnowing blower fan; Driving-belt is selected to be positioned on the groove or wheel of the different radiuses of gyration of cone pulley one, cone pulley two; Can realize different gearratios; The selection by winnowing blower fan is had in a big way from slowly to fast multiple rotating speed,, guarantee to clean the stable of effect to adapt to the complex situations of crop harvesting.
Above-mentioned cone pulley one and cone pulley two are provided with the driving groove of many different radiuses of gyration, and the radius sum of mutual corresponding driving groove is a definite value, and to adopt V belt be driving-belt between the two.Cone pulley adopts the driving groove structure, and through the V belt transmission, have simple in structure, the characteristics that production cost is low; The radius sum of corresponding driving groove is a definite value each other; When being meant V belt work; Each radius sum that is sleeved on two driving grooves on cone pulley one, the cone pulley two simultaneously is a definite value, and the technique effect of generation is, even change driving groove; The length of V belt is all consistent with tensioning state, and need not to carry out extra adjustment.
Above-mentioned cone pulley one and cone pulley two are provided with the sprocket wheel of a plurality of different radiuses of gyration, and the radius sum of respective sprockets is a definite value each other, and to adopt chain be driving-belt between the two.Cone pulley adopts chain sprocket structure, and through chain drive, has the transmission efficiency height, the characteristics that durability is good; The radius sum of corresponding sprocket wheel is a definite value each other; When being meant chain work; Each radius sum that is sleeved on the sprocket wheel on cone pulley one, the cone pulley two simultaneously is a definite value, and the technique effect of generation is, even change drive sprocket; The length of chain is all consistent with tensioning state, and need not to carry out extra adjustment.
Above-mentioned driving-belt also is equipped with tensioning apparatus.During work, tensioning apparatus is with the driving-belt tensioning, to realize the reliable transmission between cone pulley one and the cone pulley two; When speed governing is carried out in replacing driving-belt operating position, unclamp tensioning apparatus, can easily driving-belt be taken out from original operating position, and the new operating position of packing into.
Above-mentioned cone pulley one, cone pulley two, driving-belt top also are equipped with protective cover.Said protective cover can stop grass bits foreign material to fall on the speed governing transmission mechanism, to improve mechanism's reliability of operation; Can prevent that again human body touching speed governing transmission mechanism from causing injury, to improve the security performance of using.
The utility model is through two mutual inverted cone pulleies and driving-belt; Realize the different drive ratios between power transmission shaft and the selection by winnowing fan shaft; The selection by winnowing blower fan is had in a big way from slowly to fast multiple rotating speed,, guarantee to clean the stable of effect to adapt to the complex situations of crop harvesting.
