A method and a vibration feeder (1) serve to meter bulk goods, such as concrete, fibres, granulates and stone. The vibration feeder comprises a feet trough (7) and at least one vibrator (10) secured on it as well as a plurality of screw springs (13) for flexibly suspending the trough (7) from a supply container (2). A frame (14) is interposed between the supply container and the screw springs (13), said frame being tiltably mounted on the supply container (2) by means of pivots (17) and brackets (18). The feed trough (7) can be caused to assume desired angular positions by means of a drive cylinder (26) which is connected partly with the frame (14), partly with the supply container (2). This means that one and the same vibration feeder (1), even in a restricted size, can work at a considerable metering rate, since the feed trough (7) is then placed in a relatively inclined position. At the end of the metering process the feed trough (7) is rotated up to a slightly inclined, horizontal or negatively inclined position, as desired, whereby the metered amount can be adjusted with great accuracy. |
