Technical field
The invention 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 the threshing detached job, then coordinate the seed that will carry secretly in stalk to separate with straw walker, and stalk is discharged to the outer structural design of machine.In the actual production operation, when running into crop humidity or weeds when more, the combine harvester working load increases, the engine overload operation, and revolution descends, and not only threshing is not thorough, and very easily causes cut flow roller to stop up, can't normal operation.Simultaneously, cut flow roller stop up after block clearing very difficult, length consuming time, affected operation quality and the operating efficiency of facility.In addition, straw walker operation vibration and noise are large, and structure is more complicated.
Summary of the invention
The purpose of the invention is exactly the problem existed for above-mentioned prior art, design provides a kind of combine harvester of new construction to cut stream four drum threshing separating mechanisms, reaches adaptable, operation is not stopped up, operating efficiency is high, threshing performance is high, the operation vibration is little, noise is low, the uniform purpose of living load.
Basic Design of the present invention is: combine harvester is cut stream four drum threshing separating mechanisms and is comprised the first flow-cut threshing cylinder assembly, the first flow-cut threshing cylinder assembly rear side totally be inclined upwardly and axial line equipped the second flow-cut threshing cylinder assembly, the 3rd flow-cut threshing cylinder assembly, the 4th flow-cut threshing cylinder assembly and stalk throw wheel assembly, equipped hinge combined type concave plate below first, second, third and fourth flow-cut threshing cylinder assembly successively in parallel to each other; On the level height position, described the second flow-cut threshing cylinder assembly axial line is the 50-80 millimeter higher than the first flow-cut threshing cylinder assembly axial line size H1, and the 3rd flow-cut threshing cylinder assembly axial line is higher than the second flow-cut threshing cylinder assembly axial line size H
2for the 70-120 millimeter, the 4th flow-cut threshing cylinder assembly axial line is higher than the 3rd flow-cut threshing cylinder assembly axial line size H
3for the 30-80 millimeter; The diameter of cylinder size of described first, second, third and fourth flow-cut threshing cylinder assembly respectively is 400-520 millimeter, 340-400 millimeter, 400-520 millimeter, 500-600 millimeter; The drum rotation speed of described first, second, third and fourth flow-cut threshing cylinder assembly respectively is 260-460 rev/min, 400-600 rev/min, 700-800 rev/min, 800-1000 rev/min; The cylinder of described first, second, third and fourth flow-cut threshing cylinder assembly is the tooth-like cylinder of spherical bar or drum with pins.
1., simple in structure, reasonable in design, adaptable the characteristics of the invention are:, the cereal threshing performance is high, and the seed damage rate is low; 2., feed quantity is large, operating efficiency is high, power is used evenly, power loss is few, the 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; 4., facility vibration and noise are little during operation.
