Abstract

An electro-mechanical controller is provided for adjusting the pump-stroke in a variety of variable-rate positive displacement piston pumps. The electro-mechanical controller can be attached to work with existing pumps or, in some embodiments, can be integrated into the pump. Using a linear actuator coupled to a pair of nested gears, the actuation of the linear actuator can be transferred into a rotating motion capable of rotating the pump setting adjustment, allowing for “on-the-go” adjustment of the pump-stroke in the variable-rate positive displacement piston pump. The electro-mechanical controllers can be particularly useful in agricultural settings to adjust the amount of fertilizer applied to the soil in response to a variety of inputs such as the GPS or map data, or a signal from a sensor indicating the amount of nitrogen in the soil or plant.
