Abstract
The utility model discloses a biphasic agricultural automatic water feeder which comprises an alternating current power supply, a power supply circuit, a control execution circuit and a water level detection circuit. The control execution circuit comprises a relay, a transistor, a diode, a first resistor and a second resistor. The water level detection circuit comprises a high water level electrode, a central water level electrode and a main motor. If a single phase water pump is used, the single phase water pump is not needed to be connected with an alternating current contactor, and the single phase water pump is directly connected with a primary circuit of the alternating current contactor in parallel, thus, use of three-phase and single phase can be realized. The biphasic agricultural automatic water feeder provided by the utility model can be used to automatically control a three-phase water pump and the single phase water pump so as to realize the function of unattended automatic water pumping control. The biphasic agricultural automatic water feeder provided by the utility model has the advantages of simple circuit, easiness in manufacturing and stability in performance.
