Description
Technical field
The utility model belongs to agricultural machinery technological field, relates 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.
The utility model content
The utility model technical problem to be solved just provides a kind of differential longitudinal axis stream bar dental roller, and is simple in structure, through threshing, advantages of small volume.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: differential longitudinal axis stream bar dental roller, and 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 utility model 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 in the utility model (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 utility model mode, realized the output of two kinds of rotating speeds, make structure very compact.
