Technical field
The present invention relates to a kind of combine, be specifically related to a kind of combine with work tilt adjustable winnow.
Background technology
In the technique known scheme; The combine that has; The winnow that comprises built-in scraper conveyor structure, the ceding of Taiwan, threshing bin, and the winnow three be fixedly connected whole, elevator is in the operating position of going up and down to change the ceding of Taiwan; When adapting to the crop harvesting of differing heights, can cause simultaneously that the operating position of threshing bin, winnow changes.
Summary of the invention
For the winnow that comprises built-in scraper conveyor structure, and the ceding of Taiwan, threshing bin, and the winnow three be fixedly connected whole combine, the present invention has found the technical problem that this area is new, and proposes new technical scheme and solve.
The technical problem of finding has: the one, and in the grain of discharging by winnow, the broken shell of a small amount of grain phenomenon of cracking rice can appear once in a while; The 2nd, to be responsible for the grain lateral collection of threshing bin bottom is put together to the cereal screw feeder of winnow porch, the off-axis phenomenon can appear transshipping once in a while.
Through researching and analysing, the major reason that above-mentioned technical problem occurs is that the work inclination angle of winnow is excessive.When the short crop of harvesting, ceding of Taiwan operating position descends, and causes that winnow work inclination angle becomes big; The transfer efficiency of winnow descends thereupon; But the grain yield of general short crop is low, and the speed of threshing bin feeding grain is also low, though the transfer efficiency of winnow descends; Still the speed with threshing bin feeding grain is suitable but discharge the speed of grain from threshing bin, so above-mentioned technical problem and generation seldom; But, under the normal situation of the grain yield of short crop, because the work inclination angle of winnow becomes big; Transfer efficiency descends, and winnow is discharged the speed of the speed of grain less than threshing bin feeding grain in threshing bin, and grain will form in the threshing bin bottom to be hoarded; The grain of hoarding is because of can not in time being discharged by winnow; The repeatedly pushing of cereal screw feeder can be received, and the acting in conjunction of mutual extrusion friction between the grain, the broken shell of a small amount of grain phenomenon of cracking rice can be occurred; Simultaneously, the grain of hoarding also can make the rotational resistance of cereal screw feeder increase, and the live load of cereal screw feeder strengthens; The grain of hoarding in a large number can seriously silt the rotation of cereal screw feeder up, makes cereal screw feeder overload and generation off-axis phenomenon.
New technology problem based on above discovery; And to forming the new knowledge of technical problem reason; The present invention provides a kind of combine with work tilt adjustable winnow, can regulate variation according to need of work to winnow work inclination angle, the transfer efficiency of basicly stable winnow; Avoid threshing bin bottom grain to hoard and cause the broken shell of grain crack rice phenomenon and threshing bin screw feeder overload off-axis phenomenon.
The technical scheme that the present invention adopts is: a kind of combine with work tilt adjustable winnow; The winnow that comprises built-in scraper conveyor structure; Threshing bin, the ceding of Taiwan the two be fixedly connected whole; The threshing bin bottom is equipped with the cereal screw feeder, and winnow is movably connected on the threshing bin, and its work tilt adjustable joint changes.
Described winnow shifts the grain lifting of threshing bin bottom through built-in scraper conveyor structure, makes grain get into follow-up work mechanism, like dressing mechanism, or pack device.Described work inclination angle is meant the center line of winnow and the angle between the horizontal line.In general, the winnow of built-in scraper conveyor structure, under the constant situation of other condition, its transfer efficiency is closely related with the work inclination angle, and the work inclination angle is more little, and transfer efficiency is high more, and the work inclination angle is big more, and transfer efficiency is low more.
When grain header in harvesting during middle and high crop; The ceding of Taiwan is in middle and high operating position, and during corresponding winnow is in, lower position, its work inclination angle is in medium or less state; The winnow transfer efficiency is normal; Grain can not hoarded in threshing bin bottom, and the broken shell of the grain phenomenon of cracking rice can not take place, and the overload off-axis phenomenon of threshing bin screw feeder can not take place yet; When grain header in harvesting during short crop, the ceding of Taiwan is in lower operating position, can drive winnow rising operating position; Winnow work inclination angle is in big state, and its transfer efficiency descends, at this moment; Can winnow work tilt adjustment be diminished, its transfer efficiency recovers normally thereupon, and grain can not hoarded in the threshing bin bottom during harvesting operation; Also just can avoid taking place the broken shell of grain phenomenon and the threshing bin screw feeder overload off-axis phenomenon of cracking rice.
Above-mentioned winnow lower end is hinged on the threshing bin, and winnow rotates around jointed shaft, realizes that the adjusting at work inclination angle changes.Further prioritization scheme is: the work inclination-angle regulating device is set on the winnow, and the work inclination-angle regulating device comprises the pin that is fixed on the winnow, and pin is nested in the chute of location-plate, and is fixed on the location-plate through nut check.Through with pin shift position in chute, just can realize winnow different working inclination angle, nut is locked pin on the position of selecting, and prevents that pin is at work from line slip.Certainly, the work inclination-angle regulating device can adopt above-mentioned continuous adjustable mode, also can be set to the adjustable mode of high, medium and low third gear.During the harvesting long-stalked crop, ceding of Taiwan position is high, and the winnow inclination angle is little, the position is low; May influence the operation of follow-up mechanism, the work inclination-angle regulating device of winnow is placed top grade, can suitably improve the inclination angle of winnow; The operation of follow-up mechanism is avoided influencing in rising winnow position; The harvesting of the most of king-rod crops of middle-grade correspondence; Low-grade then the harvesting of corresponding short crop, the transfer efficiency of winnow is improved at the work inclination angle that can reduce winnow.
The bucket seat is set on the above-mentioned threshing bin, on the bucket seat arc chute is set, arc chute is that the axle center of the cereal screw feeder bottom threshing bin is the center of circle; The winnow lower end is nested in the bucket seat; Winnow middle part fixedly installs pin, and pin is nested in the chute, and with nut check on bucket.The lower end feeding mouth of winnow and the interface of threshing bin; Can change because of the work inclination angle of winnow, and produce the slit, cause that the grain in the threshing bin falls outward; Or raise outside the grass bits; Bucket seat is set on the threshing bin, and the bucket seat can hide the winnow lower end, alleviates or prevent that grain, grass bits in the threshing bin from leaking from the interface slit; Pin is the shift position in arc chute, just makes winnow have the different working inclination angle.Further prioritization scheme: the winnow middle part fixedly installs the pin of isolating more than two, and pin is nested in the chute, and with nut check on the bucket seat, and the centerline of winnow is on the radius in the center of circle in the axle center of cereal screw feeder bottom threshing bin.Because of arc chute is that axle center with the cereal screw feeder of threshing bin bottom is the center of circle; And the centerline of winnow is on the radius in the center of circle in the axle center with threshing bin bottom cereal screw feeder; In the middle part of winnow, fixedly install the pin shift position in arc chute that isolates more than two, when promptly changing the work inclination angle of winnow, the axle center that the center line of winnow can be in threshing bin bottom cereal screw feeder all the time is on the radius in the center of circle; Producing the direct technology effect is; In the built-in scraper conveyor structure of winnow, be installed in the lower sprocket on the cereal screw conveyor shaft, and the centre distance that is installed between the upper sprocket wheel of winnow upper end will be invariable; Can not change and change because of the work inclination angle of winnow; The tensioning state that is sleeved on the chain between the upper and lower sprocket wheel can not change yet, and the scraper conveyor structure is in the works fine state all the time, and need not to do extra adjustment.Certainly, the work inclination-angle regulating device can adopt above-mentioned continuous adjustable mode, also can be set to the adjustable mode of high, medium and low third gear, makes user's operation simpler and clearer.During the harvesting long-stalked crop, ceding of Taiwan position is high, and the winnow inclination angle is little, the position is low; May influence the operation of follow-up mechanism, the work inclination-angle regulating device of winnow is placed top grade, can suitably improve the inclination angle of winnow; The operation of follow-up mechanism is avoided influencing in rising winnow position; The harvesting of the most of king-rod crops of middle-grade correspondence; Low-grade then the harvesting of corresponding short crop, the transfer efficiency of winnow is improved at the work inclination angle that can reduce winnow.
