Device for dissemination of a spreadable material

A device for the dissemination of spreadable material, such as fertilizer in powder of granule form, comprising:

• a supported frame with a storage holder for the material for spreading with an outlet opening disposed therein;
• a spreader pipe connected at a proximal end to said holder which pipe cooperates with said outlet opening, said spreader pipe being driven for reciprocal substantially horizontal swinging, and said pipe comprises top, bottom and side walls and an outflow opening at a distal end of said pipe with a given diameter and;
• a spread pattern influencing means disposed at said distal end of said pipe comprising, a partition connected to the bottom wall of said pipe and extending vertically upwardly therefrom and which protrudes down stream from the outflow opening of said pipe over a determined length, said partition comprising top, front, rear and bottom edges, characterized in that said front edge is upstream from the rear edge, and said front edge is downstream from said proximal end and;
• a bracket disposed at the distal end of said spreader pipe, said bracket having ends fixed to said side walls of said pipe, said bracket extending laterally from side wall to side wall at a distance downstream from said outflow opening and said partition, which bracket comprises upper and lower edges displaced at a distance from each other to form passage openings and;
• a rebound surface disposed in said bracket downstream from the outflow opening of said pipe and extending transversely of and above said partition at an incline to a longitudinal axis of said spreader pipe for directing at least a portion of the spreadable material in a upward direction.
