FIELD: agriculture.
SUBSTANCE: group of inventions relates to embodiments of a tray feeder device with an adjustable level of fodder for feeding poultry. Tray device includes a fodder tray with an upwardly extending conical element located practically in the centre, and a detachable flap attached to the said fodder tray with a plurality of radially arranged ribs. At the same time the outer edge of the shutter is made with arc-shaped recesses. Shutter is equipped with element for protection against overflow, diameter of which is less than diameter of outer edge with arc-shaped recesses. Damper ribs are located at practically equal distance, and each of them passes from upper surface of element for protection against overfilling to outer edge of shutter with arc-shaped recesses, thus forming multiple loading chambers, each of which is limited by at least two ribs and one segment of outer edge with arc-shaped recesses. At least a part of the ribs has a curved upper edge. Shutter is also made with receiving part to receive cone-shaped element. Receiving part is made with circular ledge directed downwards with multiple pairs of recesses arranged opposite to each other, and each such pair of cuts has its depth.
EFFECT: technical result consists in provision of favourable conditions for poultry when eating fodder due to elimination of its physical injury.
