| 摘要 |
The invention relates to a threshing device, which is provided with function of recovering grain via entering into threshing and discharge of straw, and capable of freely adjusting air feed amount and air feed direction of screen air, thereby improving screening precision, efficiency of threshing operation, and efficiency of grain recovery. A separating plate (11K) is closely configured at the outer periphery of the rear part of a processing cylinder (10) in a threshing chamber (11), separating teeth (10b) are formed at the outer circumferential surface of the processing cylinder (10) in a recovery chamber (11F) at the rear side of the separating plate (11K) and disposed to separate grain via entering into threshing and discharge of straw from straw, and a supporting part (10c) is formed at a part along the lower side outer periphery of the processing cylinder (10) in the recovery chamber (11F) and disposed to support the discharged straw after threshing and guiding the straw to an acting zone of the separating teeth (10b). Additionally, air feed direction of screen air from a winnower is in an upper-lower free adjustment. |
