Abstract
A sliding gate type outlet port for a semi-liquid manure spreader is presented. The spreader with which the gate is used has an open topped tank of triangular cross section supported on a tractor drawn trailer. The power takeoff from the tractor is coupled to a shaft extending internally the length of the tank near the bottom. At the rear wall of the tank the shaft is coupled to a centrifugal pump which communicates with the tank and flings manure received therefrom in an arc away from a discharge opening in the pump housing. A hydraulically actuated flow regulating gate slides fore and aft across the pump exit port. The horizontal movement of the gate in a support structure allows an opening of constant height to be maintained while varying the area of the discharge opening, thus providing constant spread width under various settings of deposition density.
