A method of inhibiting dry material clogs in a work vehicle having an air boom assembly includes moving the work vehicle at a vehicle speed along a ground surface, moving dry material from a holding tank onto a conveyor, and operating the conveyor at a conveyor speed, the conveyor speed being at least partially dependent upon the vehicle speed, moving material from the conveyor into a boom assembly with a blower, dispensing the dry material onto the ground surface through a plurality of nozzles of the boom assembly, and comparing the conveyor speed to a maximum acceptable conveyor speed. If the conveyor speed is greater than the maximum acceptable conveyor speed, the method includes performing at least one of the following: alerting the operator that the conveyor speed is greater than the maximum acceptable speed, and reducing the vehicle speed to thereby reduce the speed of the conveyor.

A product distribution system for sectional control in an air boom spreader has a solid product metering assembly having: a first endless conveyor and a second endless conveyor for conveying the product from the container to the air system, the first and second endless conveyors substantially parallel to each other, the first conveyor driven independently of the second conveyor; and, a first shaft, a second shaft and a third shaft, the first shaft parallel to, separated from and driven independently of the second shaft, the second shaft parallel to and separated from the third shaft, the first shaft driving the first conveyor, the second shaft driving the third shaft to drive the second conveyor.

This document concerns a device for airflow-assisted feeding of granular material in an agricultural implement, comprising an air inlet (1611, 1612), a material inlet (167), and an outlet (162) for material-laden airflow, a roof (163), the horizontal extension of which defines a material pickup zone (160), wherein the material inlet (167), air inlet (1611, 1612) and outlet (162) are connected to the material pickup zone (160), wherein the device furthermore comprises an air inlet valve (164) containing a valve seat (1641) and a valve body (1642). The valve body is rotatable about a geometric axis which is substantially perpendicular to a flow direction at the air inlet. The document also concerns a method for airflow-assisted feeding of material in an agricultural implement, a meter housing, and an agricultural implement comprising such a meter housing. It also concerns a frame for a material pickup module and a method for forming a meter housing.

The present invention provides a plenum configured to evenly separate and distribute airflow generated by a fan into distribution lines of an agricultural machine. The plenum can utilize angled vanes symmetrically or asymmetrically arranged to form plenum chambers to provide a balanced airflow which contributes to maximizing fan efficiency, including power consumption and performance (airflow and static pressure). Accordingly, the plenum can be configured to separate the airflow and minimize imbalance between the lines during sectional control. The plenum height can be maintained for increased manufacturability and to prevent additional expansion. The plenum length can be configured within allowable space constraints of the machine yet allow airflow to develop upon separation into the lines. Vanes throughout the span of the plenum initially divide the airflow from the fan and maintain separation until the outlets.

The invention provides a pneumatic conveying system for an agricultural product applicator, which system comprises multiple fans configured to serve separate boom sections of the applicator to more efficiently conduct airflow with respect to each section. In aspects of the invention, multiple centrifugal fans of the same or similar size can be used, or multiple centrifugal fans of various sizes can be used, such as one or more larger fans and one or more smaller fans. Exemplar aspects could include three small or medium sized centrifugal fans, four small or medium sized centrifugal fans, and five small or medium sized centrifugal fans, thereby allowing the system to raise outlet air pressure at an elevated flow. Another aspect of the invention could include configuring one fan to supercharge another fan, in series, also allowing the system to raise outlet air pressure at an elevated flow.
