A spraying machine for application of treating liquids to cultivated fields, the machine including one span having a proximal end, that is a pivot point, and a distal end and including a plurality of span sections, with each span section having one electric motor control valve assembly and a plurality of nozzles arranged along each span section in a pattern such that the nozzles in a span section close to the proximal end of the span are closer to each other as compared to the nozzles in a span section towards the distal end of the machine.

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.

The application is generally directed towards an airfoil for a fluid delivery tube. The airfoil includes a securing member operably connecting the airfoil to the tube, a fin extending downward and outward from the securing member and terminating in a tip, a shield extending inward and downward from the tip of the fin, and an air guide extending from a first end of the shield.

A method for the application of agricultural fluid to a field includes determining a location of each of a plurality of nozzles of an agricultural spraying machine. A flow rate for each of the nozzles is determined based on each respective nozzle's location in the field. A field map is used to determine a crop requirement and application restriction associated with a nozzle's location. The field map contains indications of crop requirements and application restrictions. The flow rate for a nozzle is determined by comparing the nozzle's location to the field map. A flow rate signal is transmitted to each of the nozzles based on its determined flow rate.

A locust swarm amelioration method, system, and computer program product, includes detecting a locust swarm either about to form, or having formed, and controlling a drone to perform an amelioration action against the locust swarm about to form or having been formed.

A nozzle height adjustment subsystem for use with an irrigation system comprises a spool, a rotation device, and a control device. The spool includes a central hub and is configured to retain a drop hose to which a nozzle is attached. The rotation device is coupled to the spool and rotates the spool in a first direction or a second, opposite direction when it is activated. The control device includes electronic circuitry that is configured to generate a signal that activates the rotation device.

At present, the Asian country's overrated agricultural plant protection sprayer UAV (Unmanned Air Vehicle) is of limited use. Each take off can only carry about 10 liters of liquid, and a flight time of about 10 minutes. This garden-level product cannot meet the needs of large-scale agricultural development. In the United States the autonomous flight control technology for civilian use is not ready. For safety reasons, FAA cannot approve certification of UAVs payload of more than 20 kilograms to 100 kilograms of agricultural spray for business user into the commercial market for the next several years. Between now and tomorrow, the market demand is to develop a new product invention that is lower cost than the agricultural aircraft and long boom spraying tractors. Today's need is for new agricultural invention with simple to use technology and higher efficiency.

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 and will never lose control. 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. This new invention is significantly lower cost to own, operate, maintain, and less technical requirements than existing agricultural spray aircraft and long boom spraying tractors.

The disclosure of this patent will make possible the important invention for the development of large-scale agriculture.

An oscillating sprinkler that includes a frame with a first boom and a second boom engaged therewith. The booms are oriented generally parallel to each other and each of the first and second booms rotates about an axis that extends along the boom's length of the respective first or second boom. The first and second booms rotate in opposite directions to each other and are synchronized so that they rotate toward each other or away from each other in unison. First and second booms are operatively engaged with gears that are driven by a water-powered motor. One or more valves may be provided to shut off or reduce water flow from one or both of the booms. The watering pattern from the booms is such that water tends to be more evenly distributed over a ground surface upon which the sprinkler is placed.

A boom mounting assembly for attachment to an agricultural application machine is provided. The assembly includes a boom support frame which is suspended from a primary frame mounted to a chassis. The boom support frame comprises a transverse beam for supporting an intermediate section of a fluid application boom. The suspension mechanism allows both yaw and pitch of boom support frame relative to the primary frame resulting from fore and aft forces on the boom. Dampers are each connected between the primary frame and the boom support frame at a position spaced from the transverse center of the assembly. Damping of pitch and asymmetrical yaw movement of the transverse beam away from a neutral position is controlled by the first and second dampers.
