Broadcast Spreader Mechanism

An apparatus for distributing granulated material stored in a container having an outlet port, the apparatus comprising:

• a housing comprising a central bracket configured to mount to said container and at least one vane hingedly connected to a side of said central bracket, said housing having means for fixably positioning said vane relative to said central bracket in order to adjust an angle of said vane relative to said bracket.
• wherein said central bracket is configured to support 1) a power source having a driving shaft extending along an axis of rotation of said shaft, 2) a spreader plate coupled to said driving shaft for rotation therewith, and 3) a return spring encircling said threaded shaft and disposed between said spreader plate and said power source,
• wherein said spreader plate is operably disposed beneath and aligned with the outlet port of said container for distribution of granulated material therefrom,
• wherein said return spring is configured to bias said spreader plate in said closed position, blocking the flow of granular material from said outlet port of said container, when said power source is turned OFF, and
• wherein said power source is configured to rotationally drive said driving shaft when said power source is turned ON, causing said spreader plate to rotate and translate along said axis of said shaft from said closed position to an open position.
