Patent number: 11051505Abstract: A method of spraying multiple fluids from an agricultural machine includes supplying a first working fluid from a first source to a first spray nozzle, and supplying a second working fluid from a second source to the first spray nozzle. The method also includes operating at least one valve in the first spray nozzle to control flow of the first working fluid from the first source to one or more outlets of the first spray nozzle, and operating the at least one valve in the first spray nozzle to control flow of the second working fluid from the second source to the one or more outlets of the first spray nozzle. The method further includes selectively spraying the first working fluid through the one or more outlets of the first spray nozzle, and selectively spraying the second working fluid through the one or more outlets of the first spray nozzle.Type: GrantFiled: October 12, 2018Date of Patent: July 6, 2021Assignee: DEERE & COMPANYInventors: Richard A.

Publication number: 20210008582Abstract: A method of equalizing a spray system for an agricultural sprayer includes measuring an output flow rate or fluid pressure for one or more nozzles on a boom assembly, determining an amount of tilt of the boom assembly with respect to a reference frame, and associating the amount of tilt with the output flow rate or fluid pressure for each of the one or more nozzles. The method also includes determining tilt-updated flow settings for the spray system based on the output flow rate or fluid pressure and storing the tilt-updated flow settings in a spray profile for later use during a spray operation.Type: ApplicationFiled: September 28, 2020Publication date: January 14, 2021Inventors: Dennis J.

Patent number: 10786826Abstract: Embodiments of an equalization system include a spray system with a spray boom and a plurality of nozzles that have fluid flow measurement sensors to measure flow rate from each nozzle or each section of nozzles for different boom configurations. Based on a comparison of the flow indicators to the average value, target value or reference value, a deviation from a target nozzle outflow rate is determined. The deviation is proportionally applied to adjust pulse width modulated nozzle control to equalize the performance of the nozzles or sections of nozzles.Type: GrantFiled: October 12, 2015Date of Patent: September 29, 2020Assignee: Deere & CompanyInventors: Dennis J. Sullivan, Richard A. Humpal
