A localized product injection system includes a composite boom tube having a carrier fluid passage within a tube body, and at least one injection product passage within the tube body isolated from the carrier fluid passage. A plurality of port stations are provided at locations along the tube body. Each of the port stations includes a carrier fluid outlet port and at least one injection product outlet port. A localized injection interface is coupled at a port station. The injection interface includes a carrier fluid input coupled with the carrier fluid outlet port, and at least one injection product input coupled with the at least one injection product outlet port. The injection interface includes at least one throttling element in communication with the at least one injection product input, a mixing chamber, and an injection port configured for localized coupling and injection to a product dispenser.

Localized product injection system and methods for same

An agricultural implement that can concurrently cultivate and spray includes an implement support frame. A plurality of cultivator row units is coupled with the implement support frame. Each cultivator row unit of the plurality of cultivator row units includes a dispatching implement. A sprayer system coupled with the implement support frame includes a fluid holding tank coupled with the implement support frame. The sprayer system includes a fluid pump in fluid communication with the fluid holding tank. The sprayer system includes a plurality of fluid nozzles in fluid communication with the fluid holding tank. Each of the fluid nozzles of the plurality of fluid nozzles is configured to direct fluid between cultivator shovels of the plurality of cultivator row units.

Agricultural weed dispatching implements

A system is configured for nozzle control. The system includes an overall system pressure valve, configured to adjust the pressure of an agricultural product within a boom. A master node is configured to receive an overall system flow rate measurement, an overall target flow rate, and an overall system pressure measurement, the master node configured to adjust the overall system pressure valve to control the pressure of the agricultural product. A plurality of smart nozzles are configured to dispense the agricultural product, the plurality of smart nozzles each associated with an electronic control unit (ECU) and one or more individual nozzle, the smart nozzle is configured to control a nozzle flow rate of the associated one or more individual nozzles.

A system for controlling nozzle flow rate includes a master node having an expected overall flow rate module configured to generate an expected overall flow rate of an agricultural product based on one or more sprayer characteristics, and an adjustment module configured to generate an error correction based on a difference between the expected overall flow rate and an actual overall flow rate of the agricultural product. A plurality of smart nozzles are in communication with the master node, each of the smart nozzles includes an electronic control unit in communication with one or more control valves and one or more nozzle assemblies. Each of the smart nozzles includes a target smart nozzle flow rate module configured to generate a target smart nozzle flow rate of the agricultural product based on the one or more sprayer characteristics. The target smart nozzle flow rate is adjusted according to the error correction.
