Claims

[Scope of utility model registration request]

An automatic moisture detection sensor that samples the grains during drying and detects the moisture value is connected to a control circuit that compares the detection signal sent from the sensor with the detection signal and sends the result as an activation signal to the output side, and the control circuit In an automatic control device for a grain drying device, in which an operating section of a drying section is connected to an output side of the drying section, a voltage signal of "rH" level is simultaneously applied to two input terminals of the drying section. When input, an "H" level signal is output to the output terminal side, and 2
Connect the output terminal side of an AND circuit that outputs an rL level signal to the output terminal when an "H" level signal is input to one of the two input terminals and an "L" level signal is input to the other terminal. Then, the operating section is controlled to be driven by the "H" level signal outputted to the output terminal side of the AND circuit, and the operating section is controlled to be stopped by outputting the "L" level signal. An automatic control device for a grain drying device, characterized in that an output side of the control circuit is connected to one input terminal of the circuit, and an output side of a circulating operation detection circuit is connected to the other input terminal.
