内容記述(抄録等)
On the objective of separating paddy from straw beds, this study was concerned with flowing properties of paddy through straw beds under vibrating conditions. The experimental vibratory apparatus used took place an approximate sinusoidal motion in the vertical direction.
The main results were as follows :
1. The flowing of paddy through straw beds may be concerned with the difference in the property of materials. Principally the larger water contents of straws are the larger flowing resistances of paddy become.
2. Under the centrifugal effect(1>K), a long screening time is needed. In this condition, it is frequently that the paddy is kept on the surface of straw beds.
3. In the case of high centrifugal effect under large amplitudes, the jumping motion of paddy is so large that the flowing of it is obstructed.
4. As the results of increasing of centrifugal effects, the flowing property of paddy through straw beds may be more and more affected by the magnitude of amplitudes.
5. It is apparent that the resonable vibratory condition may be large frequencies with small amplitudes.
6. Taking the approximate treatment of the flowing process of paddy through straw beds, the screening length is presumed by mathematical simulations.
