Abstract:
1. An attachment for vacuuming particulate material from a storage bag having a perimeter wall with an opening, the attachment comprising: a mobile base for moving across a ground surface, the mobile base having a front, a rear, and an axle with wheels positioned between the front and rear; an intake assembly extending from the rear of the mobile base, the intake assembly including a gathering conveyor configured to move material in a laterally inward direction toward a center of the intake assembly; a vacuum conduction assembly configured to conduct a vacuum condition from an outlet opening to an inlet opening positioned adjacent to the center of the intake assembly; a hitching assembly for hitching the mobile base to another mobile base, the hitching assembly including a tow bar pivotally mounted on the mobile base and extending from the front of the mobile base, the tow bar of the hitching assembly and the gathering conveyor being positioned on opposite sides of the axle of the mobile base such that pivoting of the tow bar with respect to the mobile base effectively adjusts a vertical position of the gathering apparatus with respect to a ground surface below the gathering conveyor; wherein moving the tow bar downwardly with respect to the mobile base pivots the gathering conveyor on the axle toward the ground; and wherein moving the tow bar upwardly with respect to the mobile base pivots the gathering conveyor on the axle away from the ground.
