Drop spreader for powdered materials

A drop spreader apparatus comprising:

• a hopper configured to hold a spreadable material in a container, the container comprising an opening extending linearly across a bottom of the hopper;
• a wheel and axle assembly comprising two wheels connected by a wheel axle, the wheels and axle configured to support the hopper;
• a de-bridging and dispensing assembly positioned above the opening of the hopper, the de-bridging and dispensing assembly comprising a de-bridger mechanism configured to sift the spreadable material and a de-bridging driver mechanically coupled to the wheel and axle assembly, the driver configured to drive the de-bridger mechanism using the rotation of the wheels, where the de-bridging and dispensing assembly comprises:
• a lower rotating de-bridging and dispensing mechanism comprising at least one paddle attached to a paddle support coupled to a rotatable shaft extending across the hopper opening, the rotatable shaft configured to rotate in response to the rotation of the axle;
• an upper rotating de-bridging mechanism positioned above the lower rotating de-bridging and dispensing mechanism comprising at least one de-bridging rod supported on a periphery of two disks mounted on opposite ends of the rotatable shaft extending through the center of the upper rotating de-bridging mechanism.
