Claims

[Scope of utility model registration request]

The automatic moisture detection sensor samples drying grains and detects the moisture value, and the hot air temperature detection sensor detects the hot air temperature. Analog detection signals sent from each sensor are converted into digital detection signals and output. The output side of the control circuit is connected to an AD conversion circuit, and is connected to a control circuit that compares the AD conversion circuit with a digital detection signal sent out from the AD conversion circuit and sends the result to the output side as an activation signal. In an automatic control device for a grain drying device, in which an operating part of a drying action part is connected to a controller, a reference voltage circuit, which serves as an input power source of the circuit, is connected to the AD conversion circuit, and a reference voltage circuit is connected to the AD conversion circuit. An automatic control device for a grain drying device, characterized in that a power supply circuit for various detection sensors is connected to detect a moisture value and a hot air temperature based on set values of a variable resistor.
