The invention relates to a liquid circuit for an agricultural sprayer having a main tank, a sealed transfer system able to transfer a liquid product contained in a drum to the liquid circuit in a sealed manner, a suction mechanism designed to suck the liquid product coming from the sealed transfer system and to discharge said liquid product to the main tank, a dosing mechanism and a control unit designed to determine a quantity of liquid product to be provided to the suction mechanism for the filling of the main tank, and to control the dosing mechanism to provide the determined quantity of liquid product to the suction mechanism, in such a way as to meter the liquid product transferred from the sealed transfer system to the main tank.

The invention relates to an incorporation device for an agricultural sprayer, having a lower opening extending about a generally vertical first axis, an upper opening extending about a generally vertical second axis, and at least one side wall connecting the lower opening to the upper opening, the lower opening having a cross-sectional area smaller than that of the upper opening, the incorporation device thus generally having a funnel shape, the lower opening being further defined by a neck capable of reversibly and sealingly connecting to a closed transfer system for transferring a product to a liquid circuit of the agricultural sprayer to which the closed transfer system is connected.

An active substance supply system for an agricultural sprayer has a main liquid circuit which includes a reservoir for a main liquid and permits circulation of the main liquid, where the main liquid circuit includes one or more distribution sections which are each configured to distribute to several dispensing elements a spray liquid to be dispensed, and a feed system which is connected to the main liquid circuit and in which the main liquid is mixed with at least one separately supplied active substance to form a liquid active substance mixture, where the active substance supply system is configured to introduce the active substance mixture into the one or more distribution sections at several places.

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.

An agricultural spraying system with a system to add in a second material to the main material that can expand the spraying system to include mixing.

A spray fluid operation system for an agricultural sprayer and method for operating same is disclosed. The method comprising: providing a spray fluid in a reservoir; and conveying at least one of the spray fluid and an additional fluid into a fluid flow system by a pump and control system (PCS). The fluid flow system comprising a dispensing device configured to dispense a first pumped fluid from the PCS to a field, and a backflow system configured to pipe second pumped fluid from the PCS back to the reservoir. The method further comprises: determining a fluid level in the reservoir; receiving the fluid level in a control device; generating the second pumped fluid by the PCS; and controlling allocation of the second pumped fluid according to an allocation ratio to: a first return device and a second return device configured to return the second pumped fluid to the reservoir.

Apparatus, systems and methods for the application of water, fertilizers and herbicides to municipal plants, crop plants, indoor plants, nursery plants and the like. A self-powered mobile apparatus delivers a liquid agent. The apparatus has a reservoir for the agent and a dispenser, electronic plant identifier or geographic locator, and an electronic controller to control delivery of the agent based on an output of the electronic plant identifier or geographic locator, or an output of a remote electronic plant identifier or geographic locator.

An agricultural implement arrangement includes a container of seed having an ID tag associated therewith; an implement for applying a product to a geographic area; an electrical reader configured for reading the ID tag and providing an output signal; and an electrical processing circuit coupled with the reader and the implement. The ID tag has data representing at least one attribute associated with the seed. The electrical processing circuit receives the output signal and controls the implement, dependent upon the output signal.

The present disclosure relates to a mixer for drawing and mixing a solid product, such as a powder, with a liquid from a tank. The mixer includes a drawing wand which has a drawing tip suitable for drawing the product and a mixing vat which has a rotation shape delimited by a side wall. The discharge tip of the drawing wand leads into the top of a vat and injects the product into the vat. In one form, the mixer includes a hydraulic circuit designed to circulate the liquid between the tank and the vat. The circuit includes at least one injection duct having at least one injection nozzle that leads into the top of the vat so that the liquid from the tank flows over the side wall of the vat.

A system for dispensing agricultural products includes: a master controller, sets of agricultural product containers, meter devices, and secondary controllers. The meter devices are operatively connected to the product containers and configured to dispense products from the containers to rows in a field wherein each of the sets of containers is associated with a respective row in the field. The secondary controllers actuate the meter devices. Each secondary controller receives command data from the master controller and controls the meter devices for dispensing in response to the command data. Agricultural product from each product container is dispensed in accordance with operator defined instructions to the master controller. The instructions are capable of being provided to the master controller during the planting allowing the dispensing of individual containers to be controlled. In one embodiment the invention is a process for dispensing agricultural products at low application rates utilizing precision placement equipment.
