Abstract
The invention discloses a full-feeding longitudinal axial-flow type differential roller. A front roller spindle is arranged at the center of a front threshing roller. A rear roller spindle is arranged at the center of a rear threshing roller. The rear roller spindle is sleeved in the front rubber spindle in an idle mode. A driving box body is arranged at the front end of the front threshing roller. One input shaft penetrates from the lower side of the driving box body. A driving box body output shaft is transversely supported at both left and right sides of the driving box body. The driving box body output shaft is sequentially provided with a first bevel gear and a second bevel gear from left to right. A third bevel gear and a fourth bevel gear are sequentially fixed on the input shaft from top to bottom, wherein the first bevel gear is fixed together with the driving box body output shaft and is meshed with the third bevel gear; a second bevel gear is sleeved on the driving box body output shaft in an idle mode and is meshed with the fourth bevel gear; the driving box body output shaft is fixed together with the rear roller spindle; and the second bevel gear is fixed together with the front roller spindle. According to the invention, two driving gears on each same shaft are adopted to respectively and simultaneously drive two groups of threshing mechanisms through two meshed gears; and the full-feeding longitudinal axial-flow type differential roller has a simple structure and a small volume, and is clean to thread.
Description
Technical field
The invention belongs to agricultural machinery technological field, relate to cereal harvesting machinery, is a kind of all feeding-in combine that is applied to, and is specially adapted to the high-performance threshing unit of high yield rice results.
Background technology
When the high yield rice was gathered in the crops with all feeding-in combine, the standing grain clump under the cutting was thick close, after harvesting is carried, and the threshing of feeding threshing chamber.Under the currying of threshing cylinder bar tooth, most maturation be prone to take off seed before cylinder half section take off, and minority prematurity seed or difficulty are taken off seed to the second half section threshing.Because existing full feeding longitudinal axis stream combine all is single rotating speed cylinder, drum rotation speed is fixed, and takes off seed or under the situation of harvesting high-yield rice, the rotating speed that seems is too small for the prematurity difficulty, is prone to cause take off not net loss.Increase drum rotation speed seed damage rate and broken cane are increased, operation quality is difficult to reach the national regulation performance indications requirement of total loss rate≤2.5%, percentage of impurity≤2.0%, percentage of damage≤2%.Therefore, manufacturing enterprise all adopts the way that increases drum length to improve the threshing disengaging time both at home and abroad, solves the unclean problem of taking off, and the results in machines structure constantly increases.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of full feeding longitudinal axis streaming differential cylinder, and is simple in structure, through threshing, advantages of small volume.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: feed longitudinal axis streaming differential cylinder entirely, it is characterized in that: said cylinder is made up of threshing cylinder before separated and rear threshing roller; The front roll axle is installed at preceding threshing cylinder center, and the back roll axle is installed at the rear threshing roller center, and the back roll axle is placed in the front roll axle; Threshing cylinder front end installing drive casing before said; One power shaft penetrates from the drive case downside, and a drive case output shaft cross-brace is in the drive case left and right sides, and said drive case output shaft is disposed with first bevel gear and second bevel gear from left to right; Said power shaft is fixedly third hand tap gear and the 4th bevel gear successively from top to bottom; Wherein, first bevel gear and drive case output shaft fix and with the third hand tap gears engaged, the second bevel gear sky is enclosed within on the drive case output shaft and with the 4th bevel gear and meshes; Drive case output shaft and back roll axle are fixed, and second bevel gear and front roll axle are fixed.
As preferably, the gearratio of said first bevel gear and third hand tap gears engaged is less than the gearratio of second bevel gear and the engagement of the 4th bevel gear.
As preferably, said first bevel gear is fixed on the drive case output shaft through spline.
As preferably, said drive case output shaft is fixed through spline and back roll axle.
As preferably, said second bevel gear is provided with the output spline and the front roll axle is fixed.
As preferably, said before the threshing cylinder front end be provided with fixed disk and drive case is fixed together.
As preferably, said before between threshing cylinder and rear threshing roller by the back-up ring transition.
As preferably, said back roll axle is placed in the front roll axle through inner-ring bearing.
As preferably, said front roll axle is installed on the fixed disk through race bearing.
Threshing cylinder and rear threshing roller before the present invention is divided into threshing cylinder; Adopt last two driving gears of same axle to drive two groups of separating mechanisms [preceding (low speed) threshing cylinder and back (at a high speed) threshing cylinder simultaneously through two meshing gears respectively; Simple in structure, through threshing, advantages of small volume.In addition, differential drum shaft among the present invention (front roll axle, back roll axle) and directly spline connection of drive part (drive case output shaft, second bevel gear) omit such as running part in the middle of chain, the V belt, and structure is very compact simple.And two pairs of conical tooth shaft sleeves of the ingenious employing of the present invention mode, realized the output of two kinds of rotating speeds, make structure very compact.
