Discharge apparatus for a silo

A chip washer comprising a tank holding washing fluid, a conveyor for supplying chips into the tank, a vane for setting the fluid and therewith the chips into motion in the tank, a conduit provided with valve for removal from the tank of the foreign substances separated from the chips and a washed chips removing conveyor, this latter consisting of a screw conveyor ascending obliquely upwardly from the tank with its lower end extending into the washing fluid and the mantle of which is constituted by a strainer tube. The strainer tube of the screw conveyor is encircled by a collecting tube or trough, which returns the washing fluid running off the chips, back to the tank.

The discharge opening from a silo is formed by two generally upwardly extending bottom plates placed in a V-shaped configuration. The bottom plates are reciprocatingly movable with the aid of hydraulic cylinders. At their lower ends the bottom plates form an aperture for the discharge of goods from the silo. The bottom plates are pivotally suspended at their top margins. Their lower margins are pivotally interconnected by means of connecting pieces. The hydraulic cylinders are pivotally connected to the connecting pieces and to the bottom plates and the pivotal connections of the connecting pieces to the bottom plates and hydraulic cylinders from a linkage quadrangle. The hydraulic cylinders are arranged to move the linkage quadrangle thus produced, in such a manner that the bottom plates will swing reciprocatingly about their top edges or margins.
