A liquid feeder control system for dispensing a liquid mixture of a preset proportion includes an inlet hose, a pump, a control valve, an outlet hose, a hydraulic pressure switch (HPS), and a fluid pressure switch (FPS). The inlet hose is operably connected to an inlet of the pump and transfers liquid from a liquid storage tank to the pump. The pump pressurizes and releases the liquid to an outlet of the pump. The control valve regulates the flow. The outlet hose is operably connected to the outlet and is in fluid communication with at least one injecting device. The HPS is operably connected to the pump and a material delivery system. The HPS turns off the pump when the material delivery system stops and vice-versa. The FPS is operably connected to the pump for sensing the pressure of the liquid and is operably connected to a visual indicator.

A humidifier includes a container for containing a fluid; a cartridge for nebulizing the fluid, the cartridge configured to be fixed inside the container, the cartridge including a cartridge housing including a bottom side that is configured to contact a bottom of the container, a top side opposite to the bottom side; a back side; a front side; a left side; and a right side; and a handle on the top side of the cartridge housing, the handle projecting upward and away from the cartridge housing.

The present invention relates to a system for spraying a washing liquid, comprising a washing liquid tank, a plurality of spray members fluidically connected to the tank, a pump configured to supply the spray members with washing liquid, a plurality of valves coupled respectively to the plurality of spray members and configured to selectively transmit the pumped washing liquid to the respective spray members, wherein the plurality of valves are disposed in the form of a distribution block with an inlet of the block being configured to be fluidically connected to the pump and comprising fluidic connectors disposed in parallel and intended to be connected to spray members, and wherein the distribution block also comprises a mechanical overpressure valve disposed in parallel with the fluidic connectors and configured to be fitted on a fluidic connector of the distribution block.

An agricultural implement includes the calibration of liquid fertilizer distribution for an agricultural implement. The calibration system measures the level of the liquid fertilizer or utilizes a known volume in a container and the pressure of the liquid fertilizer. The system uses the level and pressure to calculate the density of the liquid fertilizer, which helps achieve more consistent fertilizer application. Additionally, the density of the liquid fertilizer can be used to more accurately measure the tank level of a particular tank. The system can include a tilt sensor and valves so that when the agricultural implement is traversing a hill or otherwise rough terrain, the system can accurately measure tank level and selectively draw liquid fertilizer from a particular tank or tanks to mitigate spillage. The system also can measure and monitor the tank level of the tank or tanks and automatically fill the tank or tanks based on the measured tank level.

A plural component dispensing system individually delivers separate material components to each of a plurality of proportioners. Each of the proportioners regulates volumetric flow of each of the separate material components to produce a target ratio of the separate material components associated with the proportioner. The target ratios associated with the plurality of proportioners can be the same or different target ratios. Each proportioner delivers the separate material components at the associated target ratio to one of a plurality of dispensing devices. Each dispensing device mixes the separate components received at the corresponding target ratio and delivers the components as a mixture.

A method for optimising the amount of slurry that is spread on a soil to be fertilised by means of a vehicle comprising a slurry spreader device fed by a tank through at least one conduit, wherein the concentration of at least one slurry ingredient in the conduit is acquired, a pressure difference between two points in the feed conduit upstream and downstream of a valve and the speed of the vehicle are measured, an effective volumetric flow rate of the slurry is calculated as a function of the measured pressure difference and a target volumetric flow rate of the slurry is calculated as a function of a target spreading factor and concentration of the ingredient, the measured speed and a spreading width of the slurry spreader device, and the valve is adjusted as a function of the difference between the effective volumetric flow rate and the target volumetric flow rate.

A drawback system is used with a liquid fertilizer distribution system to be used with agricultural implements. The drawback system may include a two-way, reversible pump that allows liquid fertilizer material to be transported from a system source or toward a system source. The drawback system allows liquid fertilizer that is not applied to an agricultural field to be cleared from piping, conduits, and/or other components of a liquid fertilizer system and drawn back into a holding chamber. The drawback system may also comprise a positive displacement pump in communication with a plurality of valves wherein manipulation of the valves can control the direction of the flow of liquid fertilizer, either from or toward a system/fluid source.
