PURPOSE:To prevent granular particles from being broken, to suppress noise and as well to aim at enhancing the conveying efficiency of granular particles, by forming V belt-like band sections at both side edges of a ring belt on which scraper blades are arranged at predetermined intervals, and as well by forming an opening for dropping granular particles in the belt surface between each adjacent blades. CONSTITUTION:When granular particle material stored in a supply hopper 7 is discharged from, for example, a discharge port 11B, a shut-off valve 10 for the discharge port 11B is at first opened. Then, a motor 8 is normally rotated to rotate a ring belt 14 stretched between two adjustable pulleys 12, 13 so that granular particles dropped onto the belt 14 surface from the hopper 7 are further dropped onto the bottom wall surface 9 of a transfer case 6 through particle dropping ports 18 formed into belt surface of the ring belt 14. Then, scraper blades 15 which are arranged at predetermined intervals on the surface of the ring belt 14 are slid on the bottom wall surface 9 to transfer the particles to the discharge port 11B by a short distance A. In this arrangement, V-belt-like band sections 17A, 17B are formed at both side edges 16A, 16B of the ring belt 14. |
