ABSTRACT:
A pneumatic conveying apparatus for silage and haylage, including long conveying ducts to carry the air stream with haylage and silage entrained therein. A positive displacement pump produces a flow of significant quantities of air to an air lock. The air lock has a rotor with blades traveling around the cylindrical peripheral wall and end wall defining traveling air lock compartments, the peripheral wall has an opening at its upper portion defining a feed throat receiving silage and haylage from a raised hopper. A high speed rotary impeller rotor at one side of the feed throat propels the silage-haylage into the air lock compartment. The rotor has sharp edged blades wiping along the edges of the air lock rotor blades and a boundary edge of the feed opening of the air lock. The peripheral wall of the air lock housing and the wall of the high speed impeller housing define the boundary edge across which the sharpened blades of the rotary impeller wipe to cut and remove silage and haylage as it moves through the feed throat.
