A method and a device for evaluating atomization efficiency of an electric atomizer. The method includes: obtaining an idling power consumption according to an idling voltage and an idling current of an electric atomizer to be measured when idling; obtaining a working power consumption according to a working voltage and a working current of the electric atomizer when liquid pesticide flows into the electric atomizer; obtaining atomization parameters after the electric atomizer atomizes the liquid pesticide; and calculating the atomization efficiency of the electric atomizer according to the idling power consumption, the working power consumption and the atomization parameters. The atomization efficiency of the electric atomizer for aerial application of pesticides during application process is quantitatively evaluated, which provides important indicators for testing the working performance of the electric atomizer and fills in the technical gaps in the testing of traditional equipment for aerial application of pesticides.

An agricultural spreader includes at least one delivery conduit that carries material to be spread from a bin to an exit end of the delivery conduit under the influence of air blown through the delivery conduit by a fan. A deflector is mounted proximate the exit end of the delivery pipe and deflects the material onto agricultural field in a dispersal area. A radio frequency (RF) transmitter is disposed to generate an RF signal that passes through the dispersal area. The RF signal is detectably changed when interacting with the material passing through the dispersal area. An RF receiver is disposed to receive the RF signal after the RF signal passes through the dispersal area and provides an output indicative of the RF signal. A controller is coupled to RF receiver and detects plugging of the delivery conduit based on the output of the RF receiver.

A spray pattern monitoring system includes a spray sensor disposed proximate an outlet of a spray nozzle. The spray sensor has one or more optical sensors configured to emit directional light, such as laser pulses, towards the expected position of a liquid spray emitted from the nozzle. The spray sensor can detect the absence or presence of the liquid spray based on returns of the directional light to the optical sensor.

A spraying system that includes at least one camera to determine for at least one nozzle spray angle, average of spray angle, standard deviation of spray angle, relative pressure, absolute pressure, relative flow rate, absolute flow rate, percent plugged, and/or spray pattern uniformity/variability of the spray from the at least one nozzle.
