Cup to supply both young poultry as more mature animals

摘要

The feeding dish comprises a dish (1), a central seat (2) projecting into the dish bottom (4), a guide ring (5) and a grille (50) for holding the ring relative to the dish. An adjustment sleeve (8) slides in the ring and two separated longitudinal portions (30,31) with blind housings (34,35,36), integral with the sleeve side wall (32), forming a groove (33) allow adjustment of the distance between the sleeve lower edge (10) and the central seat. A feed tube (14) sliding in the sleeve delimits an annular space. An orifice in the tube provides communication to the tube inside and the annular space. Means (17), such as a hoist, displace the tube. A skirt (18) integral with the tube lower edge (19) forms a valve able to engage the central seat and the adjusting sleeve lower edge. Means (20) gravity feed the tube interior (23).
