  • Patent number: 10244747
    Abstract: Disclosed is an apparatus for spreading solid active agents and a method for controlling the apparatus. A boom is pivotably mounted on a vehicle. A sensor arrangement detects an angular velocity and/or an angular position of the boom about a pivot axis. A control unit processes output signals of the sensor arrangement to control signals for an actuator to adjust the boom. The actuator has an active pressure side for each of the two adjustment directions of the boom. Approximately equal pressure levels prevail in the active pressure sides of two actuators operating in opposition or of a double-acting actuator, when the boom is stationary or moves only slightly in relation to the carrier vehicle. A defined differential pressure is adjustable between the active pressure sides of the actuators when the boom is shifted in relation to the carrier vehicle.

  • Patent number: 7121040
    Abstract: Method and apparatus for applying liquids to foliage with a roller and adjustable spray nozzle apparatus. A large heavy roller is pulled or pushed across a field of plants, thereby forcing the plants very close to the ground. A height adjustable applicator nozzle directly following the roller can be adjusted very close to the compacted plants. The combination of an adjustable roller and adjustable applicator nozzles allows the fluid to be released very near the plants, thereby increasing the amount of fluid transferred to the plants' surface and lowering the amount of fluid sprayed into the atmosphere. This reduces the amount of fluid required to treat a given area. The result of the invention is a savings in the cost of fluids, improved effectiveness of the treatment and an improved environmental impact where the selected fluid has a negative environmental impact.

  • Patent number: 5971294
    Abstract: A spray system is provided with improved spray control having decreased injection lag, and reducing non-uniformity in injection lag throughout the length of a spray boom. A pump is coupled to spray nozzles installed along the spray boom by manifolds which divide the spray boom into a predetermined number of zones. Each zone has a respective boom manifold, and each boom manifold is coupled through equal length line to the spray nozzles. The size of lines coupling the pump to the boom manifolds varies with position along the spray boom and restricting orifices are used in some of the connecting lines. Application systems constructed according to principles of the present invention respond quicker to changes in pump operating points than conventional systems and variability of injection lag along the length of the spray boom is virtually eliminated with the present invention.

  • Patent number: 5964410
    Abstract: In a vehicle for spreading liquid material, disclosed is a spray manifold based on an inventive variable orifice nozzle, spraying beyond the vehicle span while not extending beyond the vehicle span. Because of the inventive nozzle the vehicle is able to spray beyond the span of the vehicle with a uniform application to a swath of land over varying vehicle speeds and flow rates. The disclosed nozzle achieves a constant velocity and exit flow trajectory for a wide variety of flow rates, including low flow rates. The nozzle is particularly beneficial for vertical manifold arms with horizontally mounted nozzles because the trajectory distance is constant for a wide range of flow rates. The nozzle achieves these benefits by providing a fixed flow path and a variable flow path. The nozzle includes a substantially spherical poppet having a fixed hole orifice, variably retained by a spring adjacent to the orifice of the discharge port.

  • Patent number: 5755058
    Abstract: A method of farming comprises collecting waste material such as manure from animal farming, or effluent from food processing plants or the like in a closed container, stirring and aerating the material within the container and adding yeast and phosphoric acid to increase aerobic bacterial activity while reducing anaerobic bacteria and rendering the material into a pumpable liquid. The material is then spread across the ground by a spreading action by pumping the material through a pipe carried on the reel of a vehicle having a boom of the order of 100 feet in width so that the material is sprayed onto the ground in an even spreading action at a rate of the order of 1000 to 5000 gallons per acre. Simultaneously an oxidizing agent such as hydrogen peroxide is sprayed onto the material, preferably immediately before the material.

  • Patent number: 5522543
    Abstract: A pressurization system for a tank on a water truck includes a pipe connected at one end via a remotely controllable three-way valve directly into the engine exhaust system of the truck and at the other end into a top portion of the water tank. Engine exhaust is thus selectively introduced into the water tank to pressurize the tank. The tank includes a top-mounted fill opening with an internal, counter-weighted flapper valve. With the internal flapper valve, the truck can be driven beneath a high volume water source and water from the source, when it hits the counter-weighted flapper valve, opens the valve by urging the flapper against the action of the counter-weight, but the flapper valve is once again closed by action of the counter-weight when water flow ceases. An anti-siphon orifice in a water outlet conduit serves to prevent water from freezing in the outlet conduit once pressurization is stopped.
