Spraying boom support for agricultural sprayers, whether trailed, self-propelled and/or airborne, which includes identical articulated arms arranged on either side of the sprayer. Said arms are extended transversely to the direction of advance of the sprayer, and are coupled in an articulated manner to a central support section of the chassis of said sprayer. Each articulated arm is comprised of bar sections formed by a composite material consisting of a reinforcing agent selected from carbon fiber, fiberglass, aramid fiber, boron fiber or a combination thereof, and a matrix of epoxy, vinyl ester, phenolic, polyester resins or thermoplastic material. At its ends, the bar sections have metal nodes that make up the joints and links, also fulfilling the role of taking the concentrated loads of them and distribute them in the bar sections of composite material. In this way areas of great thickness of composite material are avoided and the advantages of each material are exploited resulting in an economical, efficient, lightweight, low maintenance and easily repairable design.

A movable agricultural product applicator system for dispensing various agricultural-related products along the ground surface of agricultural crops is provided. The application system provides a hose assembly interconnecting a supporting boom and an applicator, wherein the applicator drags along the ground surface dispensing product as the supporting boom moves by a carrier. The application system may include a swivel connection facilitating a rotational and pivotal connection of the hose assembly to the supporting boom, wherein a mounting assembly removably mounts the application system to the supporting boom. The hose assembly is designed with bending properties that enable the applicator to self-center and locate rows between crops as it is being dragged along the ground surface, as well as enable the applicator to surf above obstacles.

The present invention relates to a control system (20) provided to a spray bar (10) mounted on a carrier (1) at an angle (10) adjustable relative to the carrier (1), the control system (20) comprising an actuator for changing the angle (10) of the spray bar (10); a control device for controlling the actuator; and a damping device connected to the actuator to damp vibrations and oscillations of the spray bar (10) and thus stabilize the angle (10). The invention is characterized in that the control system (20) further comprises a recharging device operating simultaneously with the control device to compensate for a pressure change in the damping device during a change in the angle (a 10) of the spray bar (10). The invention also relates to a spray bar (10), a carrier (1) and a method of implementation.

A system and method for dispersing fluids from an agricultural vehicle includes a sprayer that dispenses the fluids and a controller cooperative with a plurality of sensors to sense vehicle travel speed, vehicle travel direction, wind speed, wind direction, and the heights of first and second nozzles from the ground surface. The controller includes a memory storing a look-up table having fan angles of the first and second nozzles, and a processor that computes first and second spray pattern on the ground surface based on the fluid dispensed through the respective first and second nozzles. The processor determines an overlap region between the first and second spray patterns, compares the determined overlap region with a pre-determined overlap, and takes corrective action automatically by changing travel speed of the vehicle or changing a duration of time the fluids are dispensed from the first and second nozzles.

An electromagnetic breakaway system having a boom assembly, including a frame including a first portion and a second portion hingably coupled to the first portion; and a hinge assembly hingably coupling the first and second portions, the hinge assembly includes first and second electromagnets coupled respectively to the first and second portions, the first and second electromagnets comprising a same charge polarity when the first and second portions form an angle within a first pivot range, the first and second electromagnets comprising a different charge polarity when the first and second portions form an angle within a second pivot range.

In certain aspects the present disclosure provides lawn/garden spraying devices and methods for their use. The support arrangement is configured to be mounted to a trailer hitch of a lawn and garden tractor, ATV or UTV. The support enables the user to selectively fix the height and angle of the nozzles on a spray boom. The support forms an adjustable Z arrangement.

One or more techniques and/or systems are disclosed for a suspended center frame attached to boom wings, and coupled to a fixed center frame. A suspended center frame can be suspended from a fixed center frame with a bearing at a pivot point to allow for pivoting in multiple axes. The suspended frame can comprise one or more dampers that are operably, pivotably coupled with the fixed frame to dampen movement of the suspended frame in the roll axis; and one or more connecting links that are operably, pivotably coupled with the fixed frame to control movement of the suspended frame in the yaw and/or pitch axis. The pivot point can be located above the center of gravity of a suspended portion of the system, and proximate a top portion of the fixed frame; and the links and dampers can be disposed at a bottom portion of the suspended frame.

The present invention discloses a formulation and an apparatus for spraying a biopesticide against corn borer and other crop pests.

The present invention relates to a control system (20) provided to a spray bar (10) mounted on a carrier (1) at an angle (10) adjustable relative to the carrier (1), the control system (20) comprising an actuator for changing the angle (10) of the spray bar (10); a control device for controlling the actuator; and a damping device connected to the actuator to damp vibrations and oscillations of the spray bar (10) and thus stabilize the angle (10). The invention is characterized in that the control system (20) further comprises a recharging device operating simultaneously with the control device to compensate for a pressure change in the damping device during a change in the angle (10) of the spray bar (10). The invention also relates to a spray bar (10), a carrier (1) and a method of implementation.

The current invention discloses several methodologies that mitigate shock loading and propensity to resonance in agricultural spray boom structures. These include a near planar linkage for decoupling the boom assembly from the vehicle. This serves to permit further aspects of the invention to: Use the combined mass of the booms and center section as the tuned mass of a tuned mass damper: Act as an enabling part of a boom compliant suspension system to mitigate shock loadings otherwise imposed on the boom system, and: Act as an enabling part of an active boom height and roll control systems to permit the accurate navigation of the boom over undulating terrain. Further aspects include the incorporation of tuned mass dampers in the boom structure and components; and the use of the mass and operation of the boom outboard breakaway sections as tuned mass dampers.
