System and method for performing rinsing operations on an agricultural sprayer

A method for performing rinsing operations on an agricultural sprayer, the method comprising:

• receiving, with a computing system, an input to initiate a rinse cycle;
• controlling, with the computing system, an operation of a plurality of valves such that a rinse liquid is permitted to flow through a recirculation conduit from a boom assembly to a product tank in response to the input to initiate the rinse cycle, wherein controlling the operation of the plurality of valves comprises:
• closing, with the computing system, a boom assembly valve of the plurality of valves;
• and
• opening, with the computing system, a recirculation valve of the plurality of valves together with closing the boom assembly valve;
• and
• activating, with the computing system, a pump for a duration of time of the rinse cycle while the boom assembly valve is closed and the recirculation valve is open, wherein the rinse liquid is conveyed through the feed conduit to the boom assembly and through the recirculation conduit from the boom assembly to the product tank while being prevented from being dispensed by a nozzle of the boom assembly.

An agricultural sprayer, comprising:

• a frame;
• a product tank supported by the frame and configured to store a liquid agricultural product;
• a rinse tank supported by the frame and configured to store a rinse liquid;
• a boom assembly supported by the frame, the boom assembly comprising a nozzle configured to receive and deliver the liquid agricultural product to a field;
• a feed conduit extending from the product tank and the rinse tank to the boom assembly and configured to convey at least one of the liquid agricultural product and or the rinse liquid to the nozzle of the boom assembly;
• a recirculation conduit extending from the boom assembly to the product tank and configured to convey the at least one of the liquid agricultural product or the rinse liquid from the boom assembly to the product tank;
• a pump arranged between the boom assembly and the product tank and the rinse tank and configured to pump the at least one of the liquid agricultural product or the rinse liquid through the feed conduit and through the recirculation conduit;
• a plurality of valves configured to regulate a flow of the at least one of the liquid agricultural product or the rinse liquid through the feed conduit and the recirculation conduit, the plurality of valves comprising:
• a boom assembly valve moveable between an open position at which delivery of the at least one of the liquid agricultural product or the rinse liquid to the nozzle of the boom assembly is permitted and a closed position at which delivery of the at least one of the liquid agricultural product or the rinse liquid to the nozzle is prevented;
• and
• a recirculation valve moveable between an open position at which a flow of the at least one of the liquid agricultural product or the rinse liquid through at least a portion of the recirculation conduit is permitted and a closed position at which the flow of the at least one of the liquid agricultural product or the rinse liquid through the at least the portion of the recirculation conduit is prevented;
• and
• a computing system configured for:
• receiving an input to initiate a rinse cycle;
• controlling an operation of the plurality of valves such that the rinse liquid is permitted to flow through the recirculation conduit from the boom assembly to the product tank in response to the input to initiate the rinse cycle, wherein controlling the operation of the plurality of valves comprises:
• closing the boom assembly valve;
• and
• opening the recirculation valve together with closing the boom assembly valve;
• and
• activating the pump for a duration of time of the rinse cycle while the boom assembly valve is closed and the recirculation valve is open, wherein the rinse liquid is conveyed through the feed conduit to the boom assembly and through the recirculation conduit from the boom assembly to the product tank while being prevented from being dispensed by the nozzle.
