Truck mounted fertilizer applicator using fluid conveying
First Claim
1. A mobile vehicle mounted spreader for particular material comprising:
- a vehicle having an operator'"'"'s cab, a frame mounting the cab, and a particulate material storage compartment mounted on said frame, said storage compartment being mounted to the rear portions of said frame;
a metering assembly and an air distribution assembly cooperating for providing a metered amount of particulate material into a fluid stream, said metering assembly being mounted between the cab and said storage compartment and adjacent an upper portion of the storage compartment;
boom means having separate vertically aligned tubes for carrying a plurality of fluid streams laterally from the vehicle frame, said separate tubes being coupled to the air distribution assembly so that each fluid stream carries a quantity of metered particulate material;
said boom means being foldable from a position extending rearwardly along the sides of said storage compartment to a position extending laterally from the vehicle frame;
said metering and air distribution assembly including a vertically oriented plenum chamber extending vertically in alignment with the respective boom means, a blower for introducing air into said plenum chamber, a plurality of outlets from said plenum chamber, a mixing chamber coupled to each of said outlets, said mixing chambers leading to the respective ones of the tubes of the boom means, said outlets and mixing chambers aligning with respective tubes of the boom means and being below the metering assembly; and
said metering assembly comprising a metering hopper, an auger conveyor for conveying material from said storage compartment to the metering hopper, a pair of conveyor belts forming the bottom of said metering hopper, each of said conveyor belts having an upper length moving from substantially the center portions of the metering hopper to the outer ends thereof, means to divide the material carried on said belts into individual portions, and means coupled to the means to divide for depositing each of the individual portions into one of the mixing chambers, whereby air from the blower passes through the mixing chamber to carry the metered material into the respective tubes of said boom means.

Abstract
A truck mounted particulate material applicator which entrains metered amounts of the particles in a fluid for conveying the material outwardly along tubes forming boom assemblies. The metering assembly and the booms are mounted in the mid portion of the truck wheel base for minimizing bouncing, and excess shock loads on the booms during travel, and also for providing a centrally located distribution point for the metering assembly. The present device includes a unique manifold for entraining particulate materials such as inorganic fertilizer or grains in fluid flow streams within tubes in which they form the boom assemblies. Each tube carries the metered air entrained material a different distance from the center to cover a wide path. Separate tubes are directed toward the rear of the truck to spread the material in the path of the truck.

6. An apparatus for conveying and metering particulate material to mixing chambers of an air distribution system including a pair of boom assemblies having a plurality of generally vertically aligned conveying tubes thereon comprising:
-
a material storage tank having an upper edge and a bottom edge; a metering hopper separate from the storage tank having means to meter material from the metering hopper into a plurality of metered portions which form separate metered streams of material, the metering hopper being above the bottom edge of the material storage tank and above an upper one of the vertically aligned conveying tubes of each of the boom assemblies, the stream of material falling downwardly past the boom assemblies and each stream being associated with one of the conveying tubes; a conveyor for conveying material from said storage tank upwardly to the metering hopper; means for establishing a stream of air into each of the conveying tubes including a vertically extending plenum for each boom assembly and a fan below each plenum for supplying air; and means to direct each of the falling separate streams of material to a separate one of the streams of air. - View Dependent Claims (5, 7, 8, 9, 10)
