Drop covers of hopper upper part are consisting of two halves pivotally connected with one another. Inclined side walls are pivotally fixed at their bases and have two profiled sectors with flanges over the entire contour thereof. Cover halves are joined with front and rear walls by means of pivot joints and are provided with two pivotally attached triangular sectors equipped with flanges. Charging device has length which may be increased in open position of drop covers and inclined side walls. ^ EFFECT: enhanced reliability in operation and increased useful volume of hopper in open position of side walls and drop covers. ^ 4 cl, 10 dwg |
