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.

A system for dispensing agricultural products includes at least one source of agricultural product; at least one agricultural product tube, a seed sensing device, a metering system, and a sensor assembly. At least one agricultural product tube is connected to the source of agricultural product. The seed sensing device is configured to control the delivery of the agricultural product. The metering system is coupled to at least one agricultural product tube and to the seed sensing device and is configured to synchronize the placement of agricultural product relative to the placement of seed. A sensor assembly includes a signal conditioning circuit. The signal conditioning circuit is configured to provide an output signal representing an indication of the presence of the agricultural product. At least one seed for use in determining the synchronized placement of seed and the agricultural product in correct proximity with one another in a seed furrow.

The present disclosure includes systems and methods for managing, cultivating, producing, preparing and distributing agricultural products. Apparatus designed to improve agricultural yield and crop performance are also disclosed. According to one embodiment, the apparatus are individually coded or tagged for remotely configuring, monitoring and modifying one or more parameters associated with each apparatus.

A distribution device to distribute a product on a surface, such as agricultural land is provided that includes at least one distribution ramp element and a product distribution circuit. The distribution circuit includes an input port in fluid communication with a product source and a plurality of nozzles fluidly linked in series. The distribution nozzles are disposed along the distribution ramp element and linked to the input port. Each distribution nozzle presents a pressure value. A pressure controller configured to equalize the pressure values of each nozzle is proved to control the pressure of the product along the distribution ramp element. The pressure controller includes a first control member and a second control member, each of the first and second pressure control members being linked in series to the plurality of nozzles and to the input port. The nozzles are disposed between the first and second control members.

A device for damaging weeds, the device having a pressure-conveyance unit, which is designed to convey a fluid under pressure, and a fluid-dispensing unit, which is fluidically connected to the pressure-conveyance unit and is furthermore developed to dispense the pressurized fluid to the weed in order to damage the weed, the fluid-dispensing unit including at least one valve that has a piezo-actuator or an electroactive polymer actuator or a magnetoresistive actuator.

A device for repelling pests includes a housing, a positioning mechanism to move the housing, at least three range-finding elements affixed to the housing along a common plane to detect a presence of a pest (e.g., an animate pest such as an animal, or an inanimate pest such as a drone) by obtaining a signal indicative of a location of the pest relative to the device, a projectile launcher affixed to the housing to fire one or more projectiles therefrom, and a controller electronically coupled to the range-finding elements, the positioning mechanism, and the projectile launcher. The controller may be configured to move the housing using the positioning mechanism until a strength of the signal obtained from each of the range-finding elements is substantially equal thereby indicating that the projectile launcher is directed toward the location of the pest, and to fire projectiles from the projectile launcher toward the pest.

In one embodiment, a method of creating a protected field is disclosed. In one embodiment, the method includes directing a first flow of air around a target space, drawing the first flow of air in through a primary air intake vent to create a first flow field envelope. In one embodiment, a second flow of air is directed within the first flow field envelope.

A system for controlling fluid flow includes a fluid inlet operable to receive a fluid flow, a fluid outlet operable to output the fluid flow, a diaphragm seat, a diaphragm operable to restrict the fluid flow between the fluid inlet and the fluid outlet by moving between an open position where the first diaphragm does not contact the diaphragm seat to a closed position where the diaphragm contacts the diaphragm seat, a spring operable to move the first diaphragm between the open position and the closed position, and a pressurized air inlet operable to receive pressurized air to move the first diaphragm between the open position and the closed position.

The present disclosure relates to a system and method for spraying one or more target objects. A primary blower system is adapted to create a relatively isolated field of circulating air by creating a primary air stream around the field of circulating air. A secondary blower system is adapted to circulate air within the isolated field by flowing a secondary air stream in directions contrary to the primary air stream. A chemical spray comprising liquid, aerosol droplets, particulate matter, or the like may be emitted into the circulating air within the field and thereby deposited on target objects within the field. Embodiments of the present disclosure may be used for agricultural, automotive, aerospace, and other applications to emit, contain, and/or recapture a spray.

Methods and systems for generating a plasma-activated liquid or gas, and applying the plasma-activated liquid for agricultural use. A system embodiment includes a hand-held device that can be pointed and directed at different target areas of a plant. A method embodiment includes generating a plasma discharge in a gas environment or a liquid environment, and applying the gas/liquid to a plant.
