A multipositional doser of loose feeds comprises a tank, inside of which a driving shaft with agitators fixed rigidly is arranged vertically, an electrical motor, arranged in the upper part of the driving shaft and connected to a coupling. The tank is equipped with electrical sensors of the upper feed level and of the lower one, an animal-recognizing system, a control unit and a consumption sensor, which are electrically connected to the inputs of the control unit by outputs thereof. Said control unit is connected, by outputs thereof, to the windings of the electrical motor, a transport system and an electromagnet, which is made in such a manner as to allow interacting with a shutter, which is mounted in a discharge neck of the tank, and the consumption sensor is a sensitive element made as a rigidly fixed bar with a discharging chute fixed thereto and with strain sensors. The consumption sensor is mounted on a rotary unit, which is a rotary platform controlled by a stepped motor, the inputs of which come to the control unit, and, according to the number of positions, the recognizing systems comprise additional sensors, and corresponding outputs thereof are connected to the inputs of the control unit. |
