And the corresponding deflector 602 being positioned at kuppe 601 and lower kuppe 603 is fitted to each other, when upper kuppe 601 and under lead
After stream cover 603 connection, corresponding deflector 602 then seamless link；Described deflector 602 is the circle of diameter 675mm-712mm
Arc plate, and be 80 °-86 ° with the axis angle of upper kuppe 601 and lower kuppe 603, accelerate by increasing deflector 602
The axially-movable speed of material, makes helical blade 501 mechanical rotation transport performance more preferable.Cone-type spiral feeding unit 5 and taper
Kuppe assembly 6 matches, and when cone-type spiral feeding unit 5 high speed rotating, forms feeding of closing in conical flow guiding cover 6
Enter space, concurrently form stronger negative-pressure air-flow.
Described kuppe cover plate 604 is positioned at the porch of kuppe 601, and matches with the entrance of upper kuppe 601, institute
State inner surface and helical blade 501 40mm apart of kuppe 601, in the case of both can meeting big feed quantity, it is ensured that
The helical blade 501 Grasping skill to material, can make the aeroperformance of helical blade 501 play best, described spiral simultaneously
The material of blade 501 is heat treated quality carbon steel, to improve wearability, increases its hardness.
Work process:
When combined harvester production operation, first material is transported in cut flow roller 3 by delivery chute, first by cutting stream concave grate
Grid concave plate 204 in assembly 2 carries out threshing separation, has been responsible for the threshing task of more than 70%；Owing to punching arc joins
Plate 205 uses two terminal circle arcuation, middle horizontal concave structure, and relative to the axial location of cut flow roller 3, material is more
The feeding mouth of longitudinal axial flow roller 8 is easily shed from cut flow roller 3 zone line.Additionally, at punching arc cross-connecting board 205
Join domain 205-2 intermediate symmetry some through holes are set, can make full use of existing space, increase seed separating area,
Improve separating power, unnecessary emersion object additionally can be avoided to enter longitudinal axial flow roller 8, increase longitudinal axial flow roller 8 on the contrary
Workload.Upper kuppe 601 inner surface and helical blade 501 are arranged and determines suitable distance, as at a distance of 40mm,
Upper kuppe 601 and lower kuppe 603 arrange deflector 602, accelerates the axially-movable speed of material, make helical blade 501
It is more preferable that mechanical rotation transports performance；When longitudinal axial flow high speed rotating, the suction airflow of effect as axial-flow pump can be produced, it is ensured that
While helical blade 501 machinery Grasping skill, coordinates stronger negative-pressure air-flow, it is ensured that make the seriality of handling and conveying, equal
Even property, it is achieved that crop smooths, commutate transition swimmingly.
Described embodiment be the present invention preferred embodiment, but the present invention is not limited to above-mentioned embodiment, without departing substantially from this
In the case of the flesh and blood of invention, any conspicuously improved, replacement or modification that those skilled in the art can make are equal
