Abstract: A flow promotion apparatus for use in conjunction with a bulk bag unloading station. The apparatus comprises a pair of spaced apart mounting brackets, a fluid actuator, a connecting rod and a push bar. The fluid actuator is pivotably connected at one end to one of the mounting brackets. The connecting rod is pivotably connected at one end to the other mounting bracket and pivotably connected at its other end to the piston. The push bar is pivotably coupled at the junction between the fluid actuator and connecting rod and actuation of the fluid actuator extends the push bar extends to agitate material along the side-walls of the bag.

Abstract: A bag holder comprising a frame assembly, a bag support, an attachment assembly and a control assembly. The frame assembly includes a base assembly with two vertical posts extending upward therefrom. The bag support is mounted on the posts for vertical movement by the control assembly.

Abstract: A hopper assembly comprising a hopper bin having a substantially trapezoidal discharge opening and a charging adapter having multiple walls, each of the walls having a vertical portion.

Abstract: An improved bulk bag unloading station is disclosed. In its simplest form, the improvement is comprised of a movable dispensing spout which is attached to and depends from an outlet of the bulk bag. As material is dispensed through the spout, the moveable spout will cause the bulk bag to elongate. Through movement of the spout, the bag is continually elongated to continually urge the flow of material from the bulk bag and to promote full discharge of the material from the bag. In the preferred embodiment, a lift and hold apparatus is provided to position the spout during initial attachment to the outlet of the bag.
