摘要： A conveying device used in weighing apparatus for conveying powder comprising a conveying cylinder (10) which is subjected to a vibrational movement by a vibrator (62) to finely control the powder exited from the cylinder (10). Inside the conveying cylinder (10), there is a shaft (50) with first and second blade segments (52, 54) which is actuable to rotate, thereby receiving powder from a loading hopper (20) and exiting the powder to an outside. The vibrational movement of the conveying cylinder (10) is irrespective of the rotational movement of the shaft (50), and either one or both of the conveying cylinder (10) and the shaft (50) is selected to operate to obtain a desired quantity of powder, ranging from a very small quantity where only the vibrator (62) operates to a very large quantity where both the vibrator (62) and the shaft (50) operate.
