ABSTRACT:
A pneumatically-operated machine for spreading granular material, such as seed, fertilizer or the like. The machine includes a metering mechanism for receiving granular material from a storage receptacle and for metering the received granular material. The metering mechanism has an interior chamber, an inlet through which the granular material passes into the interior chamber and an outlet from which the granular material exits from the interior chamber. A distributor mechanism is provided for distributing the granular material which exits from the metering mechanism. The distributor mechanism includes two main distributor assemblies spaced from one another and a separate means supply conduit connected to each of the main distributor assemblies. An ejector mechanism transfers the granular material from the metering mechanism to the distributor mechanism. The ejector mechanism is disposed below the interior chamber. The ejector mechanism has two substantially horizontal venturi nozzles, a mechanism for supplying air to the venturi nozzles, and a pair of collector nozzles. Each of the collector nozzles has a first end adjacent to one of the venturi nozzles and in communication with the outlet of the metering means. Each of the collector nozzles also has a second end connected to and in communication with one of the main supply conduits whereby air supplied to the venturi nozzles draws the granular material through the outlet of the metering means and passes the granular material through the main supply conduits to the main distributor assemblies.
