Air fertilizer spreader
First Claim
1. An air fertilizer spreader system comprising:
- a truck having a truck chassis means, a motor means, and a truck cab located on a forward portion of said truck chassis means;
fertilizer hopper means adapted to hold solid fertilizer particles located on a rear portion of said truck means;
right and left pivotally mounted boom means positioned between said fertilizer hopper means and said truck cab;
each of said right and left pivotally mounted boom means including a corresponding one of right and left pivot means, and means and first tube means;
each of said right and left first tube means extending between a corresponding one of said right and left pivot means and end means;
said right and left pivotally mounted boom means each having a stowed position and an outward position, whereby said each of said right and left boom means swings outwardly about its corresponding pivot means from a rear position of said truck chassis;
transfer means for transferring fertilizer from said hopper means to said right and left pivotally mounted boom means for subsequent spreading; and
said transfer means including second tube means communicating with said first tube means for conveying fertilizer to said first tube means and a source of air under sufficient pressure communicating with said second tube means for moving said solid fertilizer particles into said first tube means at a sufficient velocity to maintain a fluidized mass of air and fertilizer particles.

Abstract
An air fertilizer spreader mounted on a truck chassis, the truck chassis carrying a granular or pulverized fertilizer application machine. Right and left booms swing from a midship position between a truck cab and fertilizer box back towards the rear of the truck chassis. Each boom includes a plurality of boom tubes with deflectors. Rear boom tubes are also provided at the rear of the truck chassis. A screw conveyor carries fertilizer from the fertilizer transport box to an area forward of the fertilizer transport box where the fertilizer falls into opposing metering assemblies for the right and left boom. Air, acting through particle accelerators carries the fertilizer from the metering assembly to the entrance of the boom tubes, and a second particle accelerator provides additional air flow to carry the fertilizer down the length of each of the boom tubes to the point of discharge.
