Claims

[Scope of utility model registration request]

In a switch circuit equipped with a tensioning, discharging, and drying switch, when one or both of the tensioning switch or the discharge switch of the circuit is on, the "stretching/discharging" signal flows, and the drying switch is activated. It is configured so that a "drying" signal flows when it is on, and is connected to the input side of a control circuit, and the control circuit has a drying operation section connected to its output side, and the "drying" signal that is input from the switch circuit. The apparatus is configured for semi-automatic use, and sends an operating signal to the output side to automatically control only the drying operation section, excluding the circulation system, based on the "loading/discharging" signal and the "drying" signal. Separately from the circuit, a relay circuit is constructed which has a tensioning contact, a drying contact, and a discharge contact that are linked to the tensioning, discharging, and drying switches. A relay that switches the drive motor of the circulation system to high speed rotation when the discharge contact is connected, a relay that switches the drive motor of the circulation system to low speed rotation when the drying contact is turned on when the drying switch is turned on, and a relay that switches the circulatory system drive motor so that it stops at a fixed position when the tensioning contact is brought into contact when the clamping switch is turned on;
A relay contact is provided for switching the circulation system drive motor to low speed rotation when the discharge switch is turned on when the loading switch and the drying switch are turned on and the drying operation section is under operational control. An automatic control device for grain drying equipment characterized by:
