An angle-adjusting sub-assembly (6) that is part of or attached to an unmanned aerial vehicle and apparatus (1), for the targeted distribution of hazardous chemicals onto vegetation, and is comprised of: adjustable arms (7), rotary system, which adjusts the length and angle of the adjustable arms while the aerial vehicle and apparatus are airborne. An unmanned aerial vehicle and apparatus, for the targeted distribution of hazardous chemicals onto vegetation, is comprised of: the angle-adjusting sub-assembly (6), a spray assembly, a flying platform, a storage tank (2) containing pesticide, bactericide, herbicide, fungicide, or any hazardous chemical that can be sprayed on vegetation, a supporting structure (4), and a landing sub-assembly. Using of the above device decreases the runoff of toxic chemical waste to the environment, increases chemical application efficiency, and allows for the precise targeting of pests on crops.

The invention is intended for the organization of an automated process for spraying of liquid means of chemical treatment from unmanned vehicles, for example, in precise farming systems. The invention provides the use of a replaceable, marked and hermetically sealed liquid subsystem with integrated pumping chambers in a spraying device together with an integrated self-diagnosis system allowing to ensure personnel safety and the accounting of the resources of main components of the spraying device. All this in combination enables to create fully automated spraying systems.

The present invention provides an agricultural product delivery system in which a support structure or skid well is configured to rigidly support a primary product storage tank that is manufactured from a non-metallic material such as polyethylene or plastic. The product storage tank can have a capacity of at least 500 gallons, and preferably 1000 gallons, and the support structure can include multiple support ribs spaced along sides of the tank for providing rigid support for the tank and preventing deformation when filled with liquid. In addition, the product storage tank can include one or more contours or cavities for accommodating smaller chemical injection tanks positioned therein. Such chemical injection tanks can also be rigidly supported by the support structure. A spray system can mix liquid from the product storage tank and chemical from a chemical injection tank for spraying a field.

A method for applying a spray agent is described, in particular, a plant protection product, onto an agricultural area to be treated with the aid of a spraying device, including a spray agent tank and at least one fluidic connecting line from the spray agent tank to a nozzle. The method includes the following steps: selectively applying the spray agent onto an initial section of the agricultural area, and subsequently extensively applying a residual amount of spray agent onto a residual section of the agricultural area using a predefined application amount in such a way that, upon completion of the treatment of the agricultural area, essentially the entire residual amount of spray agent has been applied.

An apparatus to prevent formation of a vortex has a ring-shaped gasket having a bottom surface and a top surface; and a blade assembly mounted on the top surface and comprising a center portion and plural blades of a defined height. Each of the blades extend from the center portion to the top surface, with each pair of the plural blades defining a filter based at least in part on spacing between the pair of plural blades.

A container system for transporting and dispensing agricultural products. The container system includes a housing assembly and a set of agricultural product containers. The housing assembly has multiple slot assemblies for containers. The agricultural product containers are configured to be releasably contained within the slot assemblies. The set of agricultural product containers may include liquid agricultural product containers and dry agricultural product containers. The slot assemblies and agricultural product containers are cooperatively configured to provide the ability to utilize either of the agricultural product containers within the slot assemblies.

A modular frame for a backpack sprayer system includes a frame plate having a front surface, a back surface and first and second side edges. A first receiving channel is located along the first side edge and a second receiving channel is located along the second side edge. A support member has a first arm which is received within the first receiving channel and a second arm which is received within the second receiving channel. A stand portion extends at an angle relative to the first and second arms. A mounting member is coupled to the front surface of the frame plate and mounts a tank and a pump unit thereon. The mounting member includes opposing left and right sides, a planar top face and a front face including a concave portion to receive at least a portion of one or both of the tank and the pump unit.

A work vehicle and a commodity tank configured for mounting on a work vehicle and storing material are provided. The commodity tank includes an inboard portion extending vertically and configured to be positioned at an inboard location of the work vehicle. The commodity tank further includes an outboard portion extending horizontally from an upper end of the inboard portion and configured to extend at least partially over a ground-engaging member of the work vehicle.

The leak-proof chemical distribution system is a spray system for mounting on a vehicle, such as a truck or aircraft, for the distribution of chemicals.

The system is separated into a storage section and a distribution section.

The storage section is located within the vehicle, and thus must be leakproof. The distribution section is located outside the vehicle, thus any connections or components that may leak will not leak on the vehicle.
