FIELD: feed dispensers.

SUBSTANCE: feed dispenser includes a feed hopper and an adjoining unloading mechanism in the form of a front impeller located in a housing with unloading windows and a feed line with an intake milling cutter installed at its end. In front of the impeller, there is a lifting flap with a filter element, installed with the possibility of blocking the impeller opening. The filter element is made in the form of a two-stage air-feed mixture separator filter. The first stage of the separator filter is made in the form of a louvered lattice, the walls of which are set to the horizon at an angle exceeding the angle of friction of the feed against the wall material. The second stage is made in the form of a vertical grid for capturing small fractions, fixed on a frame, which is connected to the louver grid by means of elastic rods that allow transverse vibrations of the grid.

EFFECT: reduction of feed losses.
