The present application discloses a fluid cleaning apparatus which includes a driving assembly including a motor, a gear clutching assembly, a moving assembly, a swaying spray assembly, a sensing assembly, and a controlling module. The fluid cleaning apparatus integrates functions of movement actuation and spraying angle adjustment with the motor and achieves versatile spraying angles for spray-cleaning with apparatus configuration convertible between swaying motion and ceased swaying motion and/or between moving motion and ceased moving motion. Besides, self-propelled movement, spraying pressure modulation, and spraying angle adjustment can be controlled by the control module or manually remotely controlled by a user. Since the fluid cleaning apparatus of the present application saves the conventional installation cost and space needed, as well as resources consumed, for cleaning the bottom of an object to be cleaned, the fluid cleaning apparatus can be extensively applied to multiple fields.

An irrigation system is disclosed that includes a variable nozzle control assembly disposed or coupled to the outer-most end of the structure of a self-propelled mechanized irrigation system. The variable nozzle control assembly may be configured to control the output water/applicant as a function of the mechanized irrigation system's location in the field. As the mechanized irrigation system travels an irrigation path, the variable nozzle control assembly may dynamically change the angle, trajectory, pressure, gallons per minute (GPM) flow (flow capacity) of the water and/or applicant released from the outer most end of the mechanized irrigation structure to provide sufficient irrigational coverage to the land.

A sprayer that senses the presence or character of a surface to be sprayed includes one or more sensors configured to detect a presence or character of a surface to be sprayed; and a dispenser assembly including one or more components configured to modify at least one spray characteristic of a formulation based on an input from at least one of the one or more sensors indicative of the presence or character of the surface to be sprayed.

In one aspect, a system for controlling the operation of agricultural sprayers may a vision-based sensor configured to capture data indicative of one or more features within a field across which an agricultural sprayer is traveling. A controller of the system may be configured to identify the one or more features within the field based on the data received from the vision-based sensor and determine a position of a boom component of the agricultural sprayer relative to the one or more identified features. Furthermore, the controller may also be configured to initiate a control action to adjust the position of the boom component when it is determined that the relative position between the boom component and the one or more identified features is offset from a predetermined positional relationship defined for the boom component.

The invention relates to a device and method for applying a spraying means using a portable spraying device.

A spray system includes a spray applicator configured to apply a fluid to a grounded target, an electrostatic charge system configured to apply an electrical charge to the fluid, and a vibration system configured to provide tactile feedback to an operator of the spray system based on at least one detected operating parameter of the spray system.

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.

The invention relates to an apparatus for shooting a projectile at a target body, in particular a fluid projectile or solid projectile, which apparatus comprises a hand-held device for shooting the projectile, wherein the hand-held device comprises a drive for accelerating the projectile and a distance-measuring device for measuring a distance between the hand-held device and the target body. The apparatus also comprises a stored energy source for operating the drive, wherein the drive comprises a control unit, by means of which the drive can be controlled in accordance with the measured distance.

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 disclosure is to provide an apparatus for dispensing droplets. Provided is an apparatus for dispensing droplets, the apparatus including: a stage on which a substrate is disposed and spraying holes are disposed; a substrate moving unit for moving the substrate disposed on the stage in a first direction; a droplet dispensing unit disposed in a vertical direction above the substrate; and a droplet dispensing unit moving unit moving the droplet dispensing unit in a second direction, perpendicular to the first direction on a horizontal plane, the apparatus, further including: a distance measuring unit measuring a distance from a substrate in the vertical direction; and a control unit, wherein the control unit measures a distance between the distance measuring unit and the substrate through the distance measuring unit while moving the substrate through the substrate moving unit.
