20130161413 | SPRAYER PULSING NOZZLE FLOW CONTROL USING ROTATIONAL STEP POSITIONS - An agricultural sprayer spray head is adapted for being mounted to a spray boom together with a plurality of like, equally spaced spray heads. Each spray head includes a body containing a flow control member mounted for rotation about an axis and including a fluid control passage arrangement located for effecting an intermittent connection between a fluid inlet leading to, and an outlet leading from the body as the control member is oscillated or rotated by a powered motor so as to effect a pulsing flow through said control. passage arrangement. The powered motor operates at a speed controlled by various input parameters including vehicle speed and field and crop conditions so as to maintain a desired spray application rate. | 06-27-2013 |
20130161419 | ARRANGEMENT FOR SWITCHING NOZZLES ON THE GO FOR CONTROLLING SPRAY RATE - An agricultural sprayer includes a spray boom equipped with a plurality of spray heads, with each head having a body defining a cavity located in fluid communication with a fluid inlet and an array of four outlets leading to four nozzles respectively having different flow rates. A nozzle-select control member is mounted for rotation in the cavity and includes a fluid passage arrangement for establishing fluid connections between the inlet and different ones or combinations of the four nozzles as the control member is rotated among preselected discrete positions by an electric stepper motor, with the stepper motor being controlled in response to vehicle speed so that the spray tip capacity decreases for effecting a constant application rate as the vehicle speed decreases from a maximum permitted speed. | 06-27-2013 |
20130284826 | SPRAYER NOZZLE APPARATUS - A sprayer nozzle apparatus of an agricultural sprayer is disclosed. The sprayer nozzle apparatus is adapted for receiving a fluid from a spray line of an agricultural sprayer. The sprayer nozzle apparatus includes an apparatus housing. A control element is rotatably coupled to the apparatus housing. A plurality of nozzle connectors having a plurality of supply paths are coupled to the apparatus housing. The control element is configured to receive fluid from the spray line and selectively communicate fluid to at least one of the plurality of supply paths of one of the plurality of nozzle connectors in a first position and to at least one of the plurality of supply paths of another of the plurality of nozzle connectors in a second position. | 10-31-2013 |
20130284827 | SPRAYER NOZZLE CARTRIDGE - A sprayer nozzle cartridge for a sprayer nozzle apparatus of an agricultural sprayer is disclosed. The sprayer nozzle cartridge is adapted for coupling to a nozzle connector of the sprayer nozzle apparatus and for receiving a fluid from the sprayer nozzle apparatus. The sprayer nozzle apparatus includes an apparatus housing for supporting the nozzle connector and a control element configured to control fluid flow. The sprayer nozzle cartridge includes a cartridge housing. A plurality of nozzle tips having a plurality of flow paths are coupled to the cartridge housing. The control element selectively communicates fluid to at least one of the plurality of flow paths. | 10-31-2013 |
