The invention relates to an agricultural apparatus (1) for spreading material such as fertilizer, plant protection products or seed, comprising a distributor linkage (10) which can be folded on both sides, comprising a central part (11), where the central part (11) is connected in a rotationally fixed manner to the agricultural apparatus (2), two intermediate frames (12a,b) connected to the central part (11), in particular by joints, two lateral booms (13a,b) connected to the respective intermediate frames (12a,b), a first hydraulic actuating device (14) which connects a first of the intermediate frames (12a) to the central part (11), where the respective first boom (13a) can be moved by way of the first hydraulic actuating device (14) about a first axis of rotation (h1) pointing in the direction of travel of the agricultural apparatus (1), and a second hydraulic actuating device (15), where the respective second arm (13b) can be moved by way of the second hydraulic actuating device (15) about a second axis of rotation (h2) pointing in the direction of travel of the agricultural apparatus (1).

The present invention relates to a boom constructed from several shaped panels of material formed or shaped to overlap when assembled to form a strong, yet lightweight, structure. The boom can have two or more joined panels to form a boom with a generally triangular shaped exterior profile. The panels can have two or more lips. One lip from each panel, together with the panel faces, form a six-sided interior profile when the panels are assembled. The interiorly located lips are gussets. The gussets can form three conduits, one at each of the triangle corners. The boom can be tapered along its longitudinal axis. The panels can have ribs formed therein to provide stiffness. A folding assembly (when a secondary section is used) and sprayers can be provided. A structural top tension tube can be provided. Longitudinal ribs that act as flow paths also can be provided.

A front-boom sprayer is provided that includes a boom center section and lift arm arrangement that provides a field of view below the boom when the boom is in a raised state that is substantially free of view obstructions from torque tube or other crosswise-extending components. The lift arm arrangement may provide different link tube geometries so that the respective left and right pairs of upper and lower lift arms align with each other in the line of sight of the in-cab operator.

A rotor-suspended boom sprayer includes a sprayer body, a pair of polygonal rollers mounted on the sprayer body, and two rotor wide spray booms which are respectively located on either side of the sprayer body when unfolded, the two rotor wide spray booms being unrolled and rolled up by the polygonal roller. Each rotor wide spray boom includes at least one electric motor, at least one propeller correspondingly connected to the electric motor, several sets of rotor spray boom units connected to each other, and several spraying heads provided on the rotor wide spray boom. A self-balancing fixed height system is provided on each rotor wide spray boom to acquire height information and regulate balance and height above the ground of the boom, and the sprayer body is equipped with a main control system connected to the polygonal roller, the electric motor, and the self-balancing fixed height system.

A product application system for an agricultural applicator includes a boom assembly including a plurality of boom sections, with each boom section being pivotably coupled to at least one adjacent boom section. The system also includes a common rail product circuit spanning across a length of the boom assembly, a product pump configured to supply an agricultural product through the common rail product circuit, and a plurality of nozzle assemblies provided in association with each of the boom sections. Each nozzle assembly across the plurality of boom sections is individually coupled to the common rail product circuit. In addition, the system includes at least one pressure accumulator provided in fluid communication with the common rail product circuit, with the pressure accumulator(s) being configured to adjust a circuit pressure of the agricultural product within the common rail product circuit in response to pressure deviations from a predetermined pressure range.

Provided is a chemical spraying device which can, even when a work vehicle travels on sloped work ground, rough roads or the like, spray a chemical onto crops onto which the chemical is to be sprayed, the spraying being performed without contact with the crops. A chemical spraying device capable of being mounted on a work vehicle is provided with: a chemical tank; chemical ejecting sections for ejecting a chemical supplied from the chemical tank; a plurality of first ejection support sections which have the chemical ejecting sections, extend in the top-bottom direction, and are oriented longitudinally; and a second ejection support section extending in the left-right direction from the chemical tank side and supporting the plurality of first ejection support sections. Each of the plurality of first ejection support sections is provided to be rockable about an axis extending in the front-rear direction relative to the second ejection support section.

An agricultural sprayer system is provided herein that can include a boom assembly having a frame and a boom arm operably coupled with the frame. The boom arm can extend a first lateral distance defined between the frame and an outer end portion of the boom arm. A nozzle assembly can be supported by the outer end portion of the boom arm. A sensor can be operably coupled with the boom assembly and configured to capture data associated with a position of the boom assembly. A computing system can be communicatively coupled to the sensor. The computing system can be configured to calculate a boom assembly curvature based on the data from the sensor; determine a nozzle speed of the nozzle assembly, wherein the nozzle speed differs from the vehicle speed when the boom arm is deflected; and determine a calculated application rate of the nozzle assembly based on the nozzle speed.

A method for performing spraying operations includes monitoring a field condition of a first swath based on data received from a sensor as an agricultural sprayer makes a first pass across a field, the sensor being associated with a first boom section assembly extending over the first swath during the first pass. The method further includes controlling a nozzle assembly as the sprayer makes a second pass across the field to perform a spraying operation along the first swath based on the monitored field condition of the first swath, the nozzle assembly being associated with a second boom section assembly extending over the first swath during the second pass. Additionally, the method includes monitoring a field condition of a second swath based on data received from the sensor as the sprayer makes the second pass across the field.

A spray boom of a spray boom assembly includes a boom frame and a spray section coupled to the boom frame. The spray section includes an elongated spray pipe configured to be fluidly coupled to a fluid source and a nozzle coupled to the spray pipe. An actuator is coupled at one end to the boom frame and at an opposite end to the spray section. The actuator controllably extends and retracts to move the spray pipe and nozzle between a raised position and a lowered position.

A spray boom for spraying a fluid on a target includes a boom frame and a spray section coupled to the boom frame. The spray section includes a spray pipe configured to be fluidly coupled to a fluid source and a nozzle coupled to the spray pipe and configured to be fluidly coupled to the fluid source. An actuator is coupled at one end to the boom frame and at an opposite end to the spray section. The actuator is controllably extending and retracting to move the spray pipe and nozzle between a raised position and a lowered position. A trip assembly is coupled between the boom frame and actuator for biasing the spray section to a biased position in which the actuator and nozzle are substantially perpendicular to the underlying surface.
