Propeller lift suspension boom truss spray combination module system

Abstract

The new invention uses a ground-based heavy payload ground vehicle, trailer, or fixed ground station to deliver agriculture chemical, power and control signals to a hinged, ground-mounted, lightweight propeller lift, boom truss module using Unmanned Aerial Vehicles (UAVs) technology to unload and suspend multiple boom truss modules, extending out to cover a large spray area. This is the newest, most practical invention that is low cost and easy to use. The total weight of each suspension boom truss modules is less than 10 kilograms and can be completely unloaded by motor-driven propellers. The suspended boom truss module is hinged on the ground vehicle, trailer or ground station. It is not necessary to apply for a flight permit from the FAA. In the field, the propeller and toxic pesticides are fixed on the suspension boom truss module and hazards can be controlled to a minimum for personnel safety.
