Abstract

An automated system for loading agricultural chemical application equipment that includes actuated valves and pumps to meter appropriate quantities of chemical. The system includes either a pump or venturi to transfer chemical. The system includes sensors to provide measurements of chemical parameters. A touchscreen user interface allows the user to input chemical selections and quantities. The processing method directs the valves and pumps according to the user inputs and feedback from the sensors.

Claims

1. A system for taking a user input and controlling a system of valves and pumps to meter the specified quantities of agricultural chemicals when filling the tank of an agricultural sprayer.

2. A system according to claim 1, having an operator interface for the user to enter desired quantities of agricultural chemicals to be loaded onto the sprayer.

3. A system according to claim 1, having a method of manipulating valves and pumps to meter the users requested quantities of chemical without further input from the operator.

4. A system according to claim 1, using intermediate holding tanks with feedback sensors for the measurement of agricultural chemicals.

5. A system according to claim 1, having a chemical transfer pump with one manifold of controlled valves on the suction side for selection of the source of the chemical to be transferred and one manifold of controlled valves on the pressure side for selection of the destination of the selected chemical.

6. A system according to claim 1, being mounted on a truck or trailer for mobile use.

7. A system according to claim 1, being mounted in a stationary location such as a loading dock or a shed.

8. A system for filling an agricultural sprayer which includes apparatus for receiving feedback on system conditions, including but not limited to levels, pressures, and flows.

9. A system according to claim 8, having a programmed feature to rinse each tank containing chemical each time the chemical is inducted

10. A system according to claim 8, having the capability to run programmed cleaning cycles which are tailored to the chemical that is being cleaned from the system.

11. A system according to claim 8, having the ability to receive instruction remotely.

12. A system according to claim 8, having the capability to keep a data record of operations for inventory and accountability purposes.

13. A system according to claim 8, having the capability to override individual component operation for manual control in the event of a system malfunction

14. A system according to claim 8, having a failsafe condition where the system will go to a condition that stops the process if a sensor reading is lost, power is lost, a component malfunctions or if any tanks becomes filled to capacity.

15. A system according to claim 8, having a manifold of controlled valves for the selection of the chemical source, a flow meter for chemical quantity measurement, and a venturi to provide suction to move the chemical and induct it into the flow being transferred to the sprayer.

16. A system according to claim 8, having the capability to visually verify all quantities of chemical before they are loaded onto the sprayer.

17. A system according to claim 8, using level sensors for the measurement of chemical quantities.

18. A system according to claim 8, using load cells for measurement of chemical quantities by mass.

19. A system according to claim 8, having the ability to be powered by DC power from a truck or tractor, AC power from a stationary power grid or generator, gasoline engine powered, hydraulic or PTO power, or compressed air powered.
