Abstract
(EN)
A high-speed centrifugal threshing apparatus of a grain combine harvester, comprising a stator drum (1), a rotary concave plate sieve (2), a power input gear set (3), a transmission gear set (4), and a straw crushing apparatus (5); the rotary concave plate sieve (2) comprises a concave plate sieve (202) and an external toothed top cover (201), the external toothed top cover being fixedly mounted respectively on both ends of the concave plate sieve (202); the power input gear set (3) is positioned at one end of the concave plate sieve (202), and the power input gear set (3) engages with an external toothed top cover gear pair to make the rotary concave plate sieve (2) rotate; an input end of the transmission gear set (4) engages with the external toothed top cover gear pair, and an output end of the transmission gear set (4) is connected to the straw crushing apparatus (5); and the straw crushing apparatus (5) is positioned on the other end of the concave plate sieve (202). The centrifugal threshing apparatus integrates a threshing and straw crushing apparatus, effectively optimising the drum structure; the entire apparatus uses geared transmission, so that, compared to a traditional belt transmission structure, the threshing apparatus has a more stable rotation speed, the structure is more compact, the working performance is more reliable, and the working life is extended.

L'invention concerne un appareil de battage centrifuge à grande vitesse d'une moissonneuse-batteuse à grains, lequel appareil comprend un tambour de stator (1), un tamis à plaque concave rotatif (2), un ensemble d'engrenages d'entrée de puissance (3), un ensemble d'engrenages de transmission (4), et un appareil de broyage de paille (5) ; le tamis à plaque concave rotatif (2) comprend un tamis à plaque concave (202) et un capot supérieur denté externe (201), le capot supérieur denté externe étant monté de façon fixe, respectivement, sur les deux extrémités du tamis à plaque concave (202) ; l'ensemble d'engrenages d'entrée de puissance (3) est positionné à une extrémité du tamis à plaque concave (202), et l'ensemble d'engrenages d'entrée de puissance (3) s'engrène avec une paire d'engrenages de capot supérieur denté externe de façon à amener le tamis à plaque concave rotatif (2) à tourner ; une extrémité d'entrée de l'ensemble d'engrenages de transmission (4) s'engrène avec la paire d'engrenages de capot supérieur denté externe, et une extrémité de sortie de l'ensemble d'engrenages de transmission (4) est reliée à l'appareil de broyage de paille (5) ; et l'appareil de broyage de paille (5) est positionné sur l'autre extrémité du tamis à plaque concave (202). L'appareil de battage centrifuge intègre un appareil de battage et de broyage de paille, de façon à optimiser efficacement la structure de tambour ; l'appareil tout entier utilise une transmission à engrenages, de telle sorte que, par rapport à une structure de transmission à courroie classique, l'appareil de battage a une vitesse de rotation plus stable, la structure est plus compacte, les performances de travail sont plus fiables, et la durée de vie est prolongée.
