ABSTRACT:
There is disclosed a device (1) for automatic feeding of animals, preferably pigs. The device comprises a dispensing unit (2) over a feed plate (4) below a hopper (13). In order to achieve a simple feeding device enabling precise regulation of an amount of feed for adjusting the device to animals of different sizes, the dispensing unit (2) comprises a tubular duct (7) the upper end of which having an area which is greater than the area of the outlet (12) of the hopper (13). In the hopper, a disc-shaped element (8) enabling outflow of feed (33) from the disc-shaped element to the inner (31) of the duct (7). Thus there will be no risk of humidity absorption from feed on the feed plate (4) to the feed in the hopper (13). The feed outflow occurs at an intermediate space (34) between the disc-shaped element and the hopper and in an intermediate space (10) between the disc-shaped element and the inner wall (11) of the duct when the animals exert a lateral pressure (35) on the dispensing unit (2). The dispensing unit (2) is suspended by a control rod (5) enabling reversal of the unit (2) to normal starting position (FIG.8) after being subjected to a lateral pressure (FIG.9).
