A method and apparatus for mounting a pump stack in a self-propelled agricultural product applicator utilize a pump stack mounting arrangement including a pump stack, a crossmember with a web having an opening providing clearance for passage through the opening of at least one successive pump of the pump stack, and a removable mounting plate adapted for attachment to the crossmember and the at least one successive pump on an opposite side of the crossmember from a proximal end of the pump to provide support for a distal end of the pump stack. By removing the mounting plate, detaching any successive pump in the stack from its immediately preceding pump in the pump stack, and moving the detached part of the pump stack axially through the opening, clearance is provided for servicing a pump in the stack without removal of the whole pump stack or the crossmember.

A multipurpose solution mixer and a use method thereof are provided. The multipurpose solution mixer includes a main control unit, a solution storage unit and a solution blending unit installed in a case; an operation display unit and a liquid outlet provided on the case; and an atomization humidifying unit connected with the liquid outlet, wherein the main control unit is electrically connected with other units; the operation display unit is a display screen with touch operation functions; the solution storage unit includes sealed bottles and infusion tubes; the solution blending unit includes micropumps infusion tubes and a blending chamber, the blending chamber is connected with the atomization humidifying unit via respective infusion tubes, and the operation display unit sends instructions to the main control unit to control the micropumps to extract solutions from the sealed bottles into the blending chamber, and output a mixed solution via the liquid outlet.

The invention relates to a discharge unit (10) for discharging a final liquid having a defined final mixing ratio, in particular for agricultural purposes, having a first pre-mixing unit (12), which is designed to mix a first liquid with a first carrier liquid, in particular water, to form a first pre-diluted liquid having a first defined pre-mixing ratio, a second pre-mixing unit (14), which is designed to mix a second liquid with a second carrier liquid, in particular water, to form a second pre-diluted liquid having a second defined pre-mixing ratio, and a final mixing unit (20), which is designed to mix the first pre-diluted liquid with the second pre-diluted liquid to form the final liquid to be discharged having a defined final mixing ratio.

Variable marks are applied to the outside of bales of hay that assign each bale to a group based on pre-selected parameters collected during baling.

Metering devices for an agricultural implement are provided for applying a field input, for example, pneumatically delivered granular product including seed or fertilizer or sprayed liquid product including fertilizer and the like, to an agricultural field. In the applying of the field input, the rate of application of the dispensers of one section of the implement can be collectively varied in relation to the rate of application of the dispensers of a different section of the implement frame.

The present disclosure describes a method and system for controlling dispensing of adhesive from an applicator. The method includes pumping adhesive from a plurality of pump assemblies to a plurality of dispensing modules and measuring current draw from each of the plurality of pump assemblies. The method also includes determining an adjustment to an operating speed of each of the plurality of pump assemblies individually based on their respective current draws and adjusting the operating speed of each of the plurality of pump assemblies individually.

A control method for a two-component spray system having first and second pumps for separate fluid components includes registering a target spray pressure, registering a material-specific pressure factor margin, sensing an output pressure of the second pump, and identifying a failure condition in the event that the sensed output pressure remains further than the pressure factor margin from the target spray pressure for at least a threshold time.

Embodiments of a spray fluid operation system include a fluid flow circuit that provides several sprayer features while using a minimum number of fluid pumps. In an agricultural setting, a first pump (one function of which is filling) is integrated with a second pump (one function of which is spraying) and both located compactly underneath the solution tank. In some embodiments that include only two pumps, they are centrifugal impeller pumps. Each of the two pumps is capable of performing more than one function. Together, they provide self-primed filling, auto dilution, eductor rinsing, and so on, in a fluid-isolated manner to avoid fluid contamination.

The invention relates to a device (01, 19, 23) for foaming a viscous material (02), said viscous material (02) being conveyed through a first conveyor pipe (05) using a first conveying means (04) at a first conveying pressure, and a gas (07) being conveyed through a second conveyor pipe (08) at a second conveying pressure, and the second conveyor pipe (08) and the first conveyor pipe (05) becoming conjoined at an opening (15), and a discharge device (17) being provided downstream of the opening (15) so as to allow a pressure-relieving discharge of the mixture (14) made up of viscous material (02) and gas (07), a gas injection valve (09) being arranged at the opening (15), said gas injection valve (09) allowing to inject gas bubbles (25) into the viscous material (02).

A double tentacle pump system for a liquid sprayer includes first and second tentacle pumps positioned serially within a flow path that extends between a liquid container and the outlet of the sprayer. A motor is configured to actuate the first and second tentacle motors in response to a user directed trigger, thereby causing fluid to be moved from the container and expelled from the sprayer.
