A part between the rear side of a first tangential flow threshing roller assembly and the front side of a key straw rack is integrally inclined upwards, and second and third tangential flow threshing roller assemblies are sequentially arranged in a mode that axes are parallel to each other; a hinge combined concave is assembled below the first, second and third tangential flow threshing roller assemblies; rollers of the first, second and third tangential flow threshing roller assemblies are spherical finger rollers, or the rollers of the first and third tangential flow threshing roller assemblies are spiked rollers and the roller of the second tangential flow threshing roller assembly is a spherical finger roller. The mechanism is simple in structure, smooth in transportation, large in feed quantity, high in adaptability, not blocked during operation, high in threshing performance and kernel recovery rate and low in breakage rate.
Description
Technical field
The utility model belongs to agricultural machinery, relates generally to the threshing detached job mechanism on combine harvester.
Background technology
At present, on traditional cut flow roller combine harvester, only adopt a cut flow roller assembly to complete threshing detached job, then coordinate the seed separation of carrying secretly in stalk with straw walker, and by the structural design outside stalk discharge machine.In actual production operation, when running into crop humidity or weeds when more, combine harvester working load increases, engine overload operation, and revolution declines, and not only threshing is not thorough, and very easily causes cut flow roller to stop up, cannot normal operation.Meanwhile, cut flow roller stop up after block clearing very difficult, length consuming time, has affected operation quality and the operating efficiency of facility.
Summary of the invention
The purpose of this utility model is exactly the problem existing for above-mentioned prior art, design provides a kind of combine harvester of new construction to cut stream three drum threshing separating mechanisms, reaches adaptable, operation is not stopped up, operating efficiency is high, threshing performance is high, the uniform object of living load.
Basic Design of the present utility model is, combine harvester is cut the straw walker that stream three drum threshing separating mechanisms comprise the first flow-cut threshing cylinder assembly and are configured in its rear side, between the first flow-cut threshing cylinder assembly rear side and straw walker front side, position integral body is and is inclined upwardly and axial line equipped the second flow-cut threshing cylinder assembly and the 3rd flow-cut threshing cylinder assembly successively in parallel to each other, equipped hinge combined type concave plate below described first, second and third flow-cut threshing cylinder assembly.
1., simple in structure, reasonable in design, adaptable feature of the present utility model is:, cereal threshing performance is high, and seed damage rate is low; 2., feed quantity is large, operating efficiency is high, power is used evenly, power loss is few, operation fault is few; 3., cereal flow to carry smooth and easyly in machine, do not stop up, the seed rate of recovery and seed cleannes are high.

embodiment
Below in conjunction with accompanying drawing, the utility model optimum implementation is described in detail.A kind of combine harvester is cut the straw walker 4 that stream three drum threshing separating mechanisms comprise the first flow-cut threshing cylinder assembly 1 and are configured in its rear side, between the first flow-cut threshing cylinder assembly 1 rear side and straw walker 4 front sides, position integral body is and is inclined upwardly and axial line equipped the second flow-cut threshing cylinder assembly 2 and the 3rd flow-cut threshing cylinder assembly 3 successively in parallel to each other, equipped hinge combined type concave plate 5 below described first, second and third flow-cut threshing cylinder assembly 1,2,3.On level height position, described the second flow-cut threshing cylinder assembly 2 axial lines are higher than the first flow-cut threshing cylinder assembly 1 axial line size H
1for 50-80 millimeter, the 3rd flow-cut threshing cylinder assembly 3 axial lines are higher than the second flow-cut threshing cylinder assembly 2 axial line size H
2for 70-120 millimeter.The diameter of cylinder size of described first, second and third flow-cut threshing cylinder assembly 1,2,3 is followed successively by 400-520 millimeter, 340-400 millimeter, 400-520 millimeter.The drum rotation speed of described first, second and third flow-cut threshing cylinder assembly 1,2,3 respectively be 260-460 rev/min, 400-600 rev/min, 700 1 800 revs/min.The cylinder of described first, second and third flow-cut threshing cylinder assembly 1,2,3 all adopts the tooth-like cylinder of spherical bar, or the cylinder of first and third flow-cut threshing cylinder assembly 1,3 is that the cylinder of drum with pins, the second flow-cut threshing cylinder assembly 2 is the tooth-like cylinder of spherical bar.
When combine harvester is used for corn, soybean crops harvest operation, the cylinder of first, second and third flow-cut threshing cylinder assembly 1,2,3 adopts the tooth-like cylinder operation of spherical bar, the engine of combine harvester synchronously drives first, second and third flow-cut threshing cylinder assembly 1,2,3 and straw walker 4 motions through transmission system, three roller assemblies complete and depart from and detached job under hinge combined type concave plate 5 coordinates, and stalk or fringe core, weeds are rearward dished out outside machine through straw walker 4.
When combine harvester is used for wheat, rice crop harvest operation, the cylinder of the second flow-cut threshing cylinder assembly 2 adopts the tooth-like cylinder operation of spherical bar, the cylinder of first and third flow-cut threshing cylinder assembly 1,3 adopts drum with pins, and its job step is identical during with harvesting corn or soybean operation.
