An arrangement in a dosing device for pellets, granulates, powder, and the like, especially for use as an automatic feeder for fish for storage, comprising a feeding screw (12) which is provided with a small clearance in a conveying tube (7, 8, 9) with an input opening (6) and an outlet for the material to be conveyed. Said tube (7) extends approximately vertically at the inlet, and the outlet (15) faces downwards. In a preferred embodiment said tube has a curved portion with a vertical portion (7) at the inlet (6) which, via a curved portion (8) changes into a horizontal portion (9), said outlet (15) consisting of a downwards facing and preferably slot shaped opening in the horizontal portion (9). Said screw consists of a helical spring made from spring wire and is driven by a continuously adjustable motor at the outlet end. The free end of said screw spring is extended up into said hopper and is angular, acting as an agitator when rotated. |
