PROBLEM TO BE SOLVED: To return the spring center of gravity of a barrel tank to a shaft center position and improve the flow, by mounting a weight for taking the weight balance with a discharge port on a side wall of the barrel tank opposite to the discharge port. SOLUTION: A weight 14 is welded to and fixed on a side wall of a barrel tank 4 opposite to a cylinder 8. On this occasion, the weight 14 is weight balanced with a discharge port 18 such as a cylinder 8, a discharge cover 9, a bracket 10, a chute 13, so that a spring center of gravity of the barrel tank 4 is agreed with the shaft center of a vibrating motor 6 as a vibration generator. In this case, the weight 14 is welded and fixed on the barrel tank 4, but it can be also fastened by a bolt, and further a plurality of weights are prepared for changing a weight in accompany with the variation of a weight of the discharge port 18 side, so that the weight balance can be taken by changing a number of weights to be mounted. Further the weight can be also mounted by a magnet. |
