The invention relates to a device for the automatic and continuous feed-out of particulate material from a container 8 having a feed-out opening in the bottom by the use of a disc 6 which is horizontally movable beneath the opening. The device is especially suitable for use in the calcification of lakes in which there is a lack of energy sources other than flowing water. According to the invention, the disc is driven by the successive filling of a vessel 2 with water conducted from the water course, whereupon the vessel drops down, accompanied by simultaneous driving of the disc and tensioning of a spring 4. Once the vessel has reached a lower end position, it is emptied of water, whereupon it is returned by the spring to its original position. <IMAGE> |
