The inner surface of the spray direction assembly is configured to modify the trajectory of all liquid that leaves the outer edge of the disc.

A method for an agricultural application operation is provided herein. The method includes receiving a target application condition for an agricultural product to be exhausted from a nozzle assembly through an input device. The method also includes receiving an agricultural product flow condition and data related to boom movement from a sensing system. In addition, the method includes receiving a first duty cycle from a computing system. The method further includes determining a detected application condition based on the agricultural product flow condition, the data related to boom movement, and the first duty cycle with the computing system. Lastly, the method includes generating a duty cycle command based on a comparison of the target application condition to the detected application condition with the computing system.

A pretreatment device includes a platen, a guide that guide a conveyance of the platen from a set position at which a recorded medium is set on an upper surface of the platen, a spray that sprays a pretreatment agent onto the recording medium set on the upper surface of the platen, an input portion into which is input at least one of an application range of the pretreatment agent onto the recording medium and an application amount of the pretreatment agent, a processor; and a memory storing computer-readable instructions. The computer-readable instructions also includes setting, on the basis of at least one of the application range and the application amount input into the input portion, at least one of a conveyance speed of the platen and a spray duty ratio that is a ratio of a spray time during a spray period of the pretreatment agent.

A method for optimising the amount of slurry that is spread on a soil to be fertilised by means of a vehicle comprising a slurry spreader device fed by a tank through at least one conduit, wherein the concentration of at least one slurry ingredient in the conduit is acquired, a pressure difference between two points in the feed conduit upstream and downstream of a valve and the speed of the vehicle are measured, an effective volumetric flow rate of the slurry is calculated as a function of the measured pressure difference and a target volumetric flow rate of the slurry is calculated as a function of a target spreading factor and concentration of the ingredient, the measured speed and a spreading width of the slurry spreader device, and the valve is adjusted as a function of the difference between the effective volumetric flow rate and the target volumetric flow rate.

Embodiments of the present disclosure generally relate to apparatus and methods for manufacturing continuous sucker rods with protective coatings. One embodiment provides a coating system including a first drive station disposed on a first end of a coating line, a second drive station disposed on a second end of the coating line to move a continuous sucker rod along the coating line from the first drive station to the second drive station, a heater disposed along the coating line, and a first coating station disposed along the coating line.

Object: A liquid material application apparatus and a liquid material application method are provided with which a liquid material can be discharged in a predetermined discharge amount per unit time regardless of a relative moving speed in a series of application works.

Solution: The liquid material application apparatus includes a discharge head, a robot moving the discharge head relative to a workpiece, a movement control unit controlling relative movement of the discharge head and the workpiece, and a discharge control unit controlling an operation of discharging a liquid material from a discharge head, wherein the discharge control unit executes, in a switchable manner in accordance with an application program, first mode discharge control of changing a discharge amount of the liquid material, which is discharged from the discharge head per unit time, depending on a relative moving speed between the discharge head and the workpiece, and second mode discharge control of operating the discharge head to discharge the liquid material in a predetermined discharge amount per unit time regardless of the relative moving speed. The liquid material application method is implemented using the liquid material application apparatus.

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 apparatus for spraying fluid phase color is integrated into a cladding manufacturing machine and synchronized with the manufacturing process. The apparatus is attached to the basket through which the concrete of the claddings is poured into a mould; color spraying initiates after completing the concrete filling phase of the manufacturing of the cladding and the basket retreats to its starting point. Color guns, attached to the basket, connect to color buckets and pump and condensed air pumps to deliver sprayed fluid color onto the top surface of the claddings. A control unit controls the color spraying via a sequential, parallel or pre-selected program or set of values of parameters that determine the final design or pattern on the claddings surface.
