PRODUCT DIVERTER VALVE AND COLLECTOR APPARATUS FOR AIR DRILLSEEDING SYSTEM

摘要

An improved collector assembly comprises a generally hollow body mounted bel ow a product supply tank for receiving plural streams of materials metered from the tank. Individual upright passages through the body corresponding in number to the metered streams from the tank receive the gravitating product streams and direct each stream into either o r both of an upper loading zone and a lower loading zone in the passage. A diverter valve associated wi th each upper loading zone can be set to close off the upper loading zone entirely while; opening only the lower zone or closing off the lower loading zone while opening only the upper loading zone . Thus, air streams passing transversely through the upper and lower loading zones respectively can be supplied with variable amounts of metered product, depending upon the position of the diverter valve within each passage. By providing multiple supply tanks and multiple collector assemblie s, various product delivery scenarios can be achieved including single shoot, double shoot and triple shoot effects. In a preferred form of the invention all diverter valves are actuated by a comm on actuating mechanism for simultaneous adjustment.
