An unloader for discharging and feeding dry, granular type materials from bulk bags. Among the many improvements of the discharge apparatus is an open frame (20) and offset discharge location. Other improvements include an I-beam (23) and frame design that keeps the hoist (25) movement within the four corner posts of the frame. The unloader may be provided with vibrators, vibration isolators, load cells, actuators (107, 108), massage paddles, or plates (106, 109) to assist in the discharge function.

I claim: 1. A bulk bag unloader comprising at least one bottom frame, unloader frame brackets secured to the bottom frame, an adjustable frame constructed without cross bracing, a top frame secured to the adjustable frame, an I-beam secured horizontally to the middle of the top frame, said I-beam b
I claim: 1. A bulk bag unloader comprising at least one bottom frame, unloader frame brackets secured to the bottom frame, an adjustable frame constructed without cross bracing, a top frame secured to the adjustable frame, an I-beam secured horizontally to the middle of the top frame, said I-beam being substantially the same length as the adjustable frame is wide, a trolley for moving a hoist along the I-beam within the top frame: a hoist coupled with the trolley for lifting a bulk bag up and down; and a bag support hopper supported by the unloader brackets. 2. The unloader of claim 1, further comprising a bag tray adapted to support a bulk bag and secured in a sraced, off-center relationship to the frame such that the hoist positioned over a bulk bag's center of gravity can lift a bulk bag from the ground, move it along the I-beam, and position it on the bag tray. 3. The unloader of claim 1, wherein the frame is sized such that the vertical centers of gravity of two horizontally adjacent bulk bags can be inside the frame. 4. The unloader of claim 1, the hopper comprising hopper brackets adapted to support the hopper by the unloader frame brackets, and further comprising at least one load cell disposed between the hopper brackets and unloader frame brackets. 5. The unloader of claim 1, further comprising at least one vibration isolator disposed between the hopper brackets and unloader frame brackets. 6. The unloader of claim 5, further comprising a vibration flange secured to the hopper. 7. The unloader of claim 1, further comprising a hopper flange ring secured to said hopper. 8. The unloader of claim 7, further comprising a discharge device plate secured to said hopper flange ring. 9. The unloader of claim 8, further comprising a discharge device removably secured to said discharge device plate. 10. The unloader of claim 1, further comprising a swiveled seat mounted to an unloader adjustable frame. 11. A bulk bag unloader comprising at least one bottom frame, a plurality of unloader frame brackets secured to the bottom frame, a bag support hopper supported by the unloader brackets, an adjustable frame constructed without cross bracing, a top frame secured to the adjustable frame, an I-beam secured horizontally to the middle of the top frame, said I-beam being substantially the same length as the adjustable frame is wide, a trolley for moving a hoist and bulk bag along the I-beam within the top frame, a hoist coupled with the trolley for lifting a bulk bag up and down, and a seat mounted to the unloader.
