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.

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.

The method also includes determining an effect of the emission rate of each respective nozzle assembly on the initial aerial distribution profile of the fluid across the distribution width. The method also includes controlling the operating parameter of each respective valve assembly to adjust the emission rate of each respective nozzle assembly to generate a compensated distribution profile.

An electro-hydraulic actuation system for a sprayer comprises a hydraulic system, a hydraulic actuator, an electric actuator and a sprayer. The hydraulic system is for pressurizing a hydraulic fluid. The hydraulic actuator is powered by the hydraulic system. The electric actuator controls actuation of the hydraulic actuator by the hydraulic system. The sprayer is actuated by the hydraulic actuator.

The automated system comprises a boom lift having a linear track disposed thereon, wherein the linear track is disposed horizontally with respect to the height of the building; a robotic mechanism slidably mounted on the linear track of the boom lift, the robotic mechanism further having an end effector adapted for supporting a spray nozzle thereon; a visual monitoring system configured to scan structural characteristics and profiles of the wall; a computing device disposed in communication with the visual monitoring system and the robotic mechanism, wherein the computing device is configured to receive the scanned structural characteristics and profile of the wall from the visual monitoring system; and controller communicably coupled to the computing device, the controller configured to independently control operation of respective ones of the robotic mechanism, and the spray nozzle according to the scanned structural characteristics and profiles of the wall.

The present invention introduces a painting head (403) for a spraying device, and a working tool module for a working tool. The device comprises two sensors, a gyroscope (301a) and an accelerometer (301b), for sensing positional and angular data of the painting head (403) or the working tool module. The controller (103, 305) calculates the desired relative angle of the painting head (403) in view of the longitudinal axis of the device so that when the user manually moves the device, the controller (103, 305) and the motors (104) automatically align the painting head (403) or the working tool module with a rotating movement in a substantially orthogonal direction towards the desired or treated surface (405) or towards the counter part element.

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.
