Description
Technical field
The invention belongs to agricultural machinery technological field, particularly a kind of closed coaxial differential arch dental roller that is used for half-feeding combine.
Background technology
Morphological feature such as super hybridization rice has the output height, tiller prosperous and cane is thick.When gathering in the crops with half-feeding combine, the standing grain clump under the cutting is thick close, after header boundling chain boundling is carried, changes by the clamping conveying of feeding chain and with the threshing of cane upper half part (containing the fringe part) feeding threshing chamber.Under threshing cylinder bow tooth " currying ", most of maturation easily 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 half-feeding combine all is single rotating speed cylinder, drum rotation speed is fixed, and takes off seed or feeding under the thick situation of standing grain clump, seems too small for the prematurity difficulty, easily causes and takes 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 middle percent of loss≤2.5%, percentage of impurity≤1.0%, percentage of damage≤0.5%.Therefore, both at home and abroad manufacturing enterprise all adopts the way that increases drum length to solve to take off unclean problem, cause the volume of cylinder to increase complex structure.
Summary of the invention
It is big to the present invention is directed to the existing existing above-mentioned volume of cylinder that is used for half-feeding combine; baroque weak point; provide a kind of volume little, simple in structure, the closed coaxial differential arch dental roller that is used for half-feeding combine and semi-feeding rice and wheat thresher that threshing is effective.
The technical scheme of closed coaxial differential arch dental roller of the present invention is finished in the following way: a kind of closed coaxial differential arch dental roller that is used for semi-feeding combine harvester and semi-feeding rice and wheat thresher, this cylinder comprises enclosed low speed cylinder, enclosed high speed rotary-drum, hollow shaft and drum shaft, wherein, the low speed cylinder is fixed on the hollow shaft, the head of low speed cylinder is truncated cone-shaped, head at the low speed cylinder is equipped with importing tablet, is provided with several bow teeth of line arrangement in the shape of a spiral on the cylindrical shell face of cylinder of low speed cylinder; High speed rotary-drum is fixed on the drum shaft, is provided with several bow teeth of line arrangement in the shape of a spiral on the cylindrical shell face of cylinder of high speed rotary-drum; Hollow shaft sleeve locates to be equipped with thrust bearing and regulating sleeve between high speed rotary-drum on the drum shaft and low speed cylinder on drum shaft, be used to eliminate the assemblage gap between high speed rotary-drum and the low speed cylinder, in case two cylinder strings are moving; Between high speed rotary-drum and low speed cylinder, be provided with the transition circle, in case crop from the low speed cylinder when high speed rotary-drum moves axially, fall in the gap between high speed rotary-drum and the low speed cylinder and result in blockage, the transition circle is fixed on the low speed cylinder, is provided with the bow tooth on the transition circle; On the hollow shaft at place, low speed cylinder outer end, double vee-pulley two is housed; Drum shaft at place, low speed cylinder outer end stretches out one section in the axis hole of hollow shaft, at the drum shaft that stretches out a section in the axis hole of hollow shaft vee-pulley one is housed.
Closed coaxial differential arch dental roller of the present invention is to be installed in as follows in semi-feeding combine harvester or the semi-feeding rice and wheat thresher: closed coaxial differential arch dental roller of the present invention is contained on the threshing chamber frame, low speed cylinder and high speed rotary-drum are positioned at the threshing chamber that drum cover constituted that is provided with grid-type concave and spiral guide plate is housed, wherein the low speed cylinder is positioned at the left side of threshing chamber, high speed rotary-drum is positioned at the right side of threshing chamber, is cleaning room below threshing chamber; Left side at threshing chamber is a feeding mouth, is provided with feeding chain and grip block on feeding mouth; On the right side of threshing chamber is straw outlet, at the drum shaft right-hand member Lysimachia sikokiana chain driving wheel is housed.
During operation, the low speed cylinder rotates with the required minimum speed of rice-wheat threshing, and high speed rotary-drum is said the fair speed rotation that allows with rice-wheat threshing.Taken off the importing tablet of crop and imported, in the arc space that constitutes by threshing cylinder and grid-type concave, curried the rubbing threshing, and carried from left to right, moved axially to high speed rotary-drum from the low speed cylinder by the clamping of feeding chain by low speed cylinder head; The seed of taking off is thrown to the cleaning room that is positioned at below the threshing cylinder from concave grate under centrifugal action, and the cane after threshing is surrendered the Lysimachia sikokiana chain by the feeding chain, outside straw outlet discharge machine.In whole process, 80% above ripe seed taking off on the crop fringe at the low speed cylinder than under the slow-speed of revolution, take off seed and after entering high speed rotary-drum, taken off and remain a small amount of immature difficulty, thereby both solved seed and purified problem, again balance percent of loss and percentage of damage and percentage of impurity three contradiction, can obtain the good working performance.
Use the present invention and both can solve super hybridization rice results and the difficult unclean problem of taking off of kind of taking off, can solve contradiction between percent of loss, percentage of damage and the percentage of impurity preferably again.The present invention also has characteristics such as can not stop up between compact conformation, reliable operation, the high low speed cylinder.Use the structure that present technique does not change existing half-feeding combine and semi-feeding thresher threshing chamber.
