A massager system for facilitating the rapid unloading of bulk material stored in a semi-rigid bag. The system includes a frame from which the bag is suspended. The bag has a discharge spout in the bottom end thereof that is secured to a complementary hopper. The system includes two massager paddles that are seated against the bottom end of the bag on opposed sides of the hopper. The massager paddles are secured to the frame so as to be able to pivot upwardly. A single actuator, such as a pneumatic drive cylinder, is suspended directly from the massage paddles. The actuation of the drive cylinder causes the simultaneous upward movement of the paddles so that the paddles enhance the movement of the contents of the bag out through the bag discharge spout.

[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [1.] A massager system for facilitating the unloading of a bag containing bulk material, the bag being formed to have a bottom section with a discharge opening from which the bulk material flows from the bag in a vertical path, said massager system including:a frame for suspending the bag so that the bottom section thereof is located above ground level;two massager paddles attached to said frame and being generally horizontally oriented so that an upwardly facing surface of each thereof is located against the bottom section of the bag and on opposite sides of the vertical path, said massager paddles being also positioned to at least partially surround the discharge opening in the bag and, wherein said massager paddles are pivotally attached to said frame so as to pivot about a pivot axis towards the discharge opening;an elongate torque arm fixed to and extending in a vertical direction from each said massager paddle on a side of said respective pivot axis remote from said massager paddle, each said torque arm being oriented in directly opposing relation for movement toward and away from each other about said respective pivot axes; anda single actuator connected directly to both said torque arms at a location spaced vertically from said pivot axes for simultaneously displacing said torque arms and said massager paddles.
