とするものである。Furthermore, in order to enhance the drying function, each part of the dryer is equipped with a hot air temperature regulator, wind pressure regulator, fire heat generator, automatic fire extinguisher, grain feeding rate regulator, etc. to automate each part as appropriate. Since the operation of the drying section is controlled by an operation box installed in the drying section, an alarm system that simply displays the operating status of each component would make it difficult to identify the location of each component. In addition, countermeasures are delayed, resulting in various problems such as frequent splitting of grains, dry spots, and overdrying. In view of the above-mentioned drawbacks, the present invention has been developed to provide a new automatic alarm system that greatly improves the conventional alarm system, can immediately identify and discover the cause of failure in each rock, and prevents the occurrence of faulty grains in dry grains. The aim is to develop and provide a device equipped with the following.

極めて明確にして即時に対応して適確な処置ができる。Therefore, the grains are put into the grain tank 5 at the top of the machine, and some of them flow down into the grain channels 3, 3 to form a grain layer. The drying action is carried out across from the chamber 2 to the artificial air chambers 4, 4.
Then, the dried grains are discharged into the grain tank 10 by the discharge valves 9, 9, conveyor 11, elevator 6, conveyor 8.
The grains are returned to the grain tank 5 via the grain distribution disk 7 and subjected to circulation tempering drying. To explain the case where the upper screw conveyor 8 malfunctions, the grains tinned by the elevator 6 flow back into the machine and accumulate, and due to this load (see Fig. 4) the thermal alarm, which is one of the abnormality detection devices, The contact 14a of the relay is activated and the output is passed through the sense line to be inputted to the first logic circuit AND1 and the second logic circuit OR2, respectively, and the first logic circuit ANDI receives the input of the flicker pulse of the flicker signal generator 27. outputs the same type of pulse to make the alarm lamp on the motor side blink continuously, and the second logic circuit OR2 outputs the same type of pulse as "1".
'', the output is amplified by the transistor and excites the electromagnetic coil R2 for emergency operation stop, and the control circuit (Fig. 3)
The normally closed contact R2 is opened, the motor 14 is stopped via the electromagnetic contactor MC, and the operation display lamp Lo is extinguished. It should be noted that each lamp L, , -, , L, when the contacts 18, 19, 21, 22, 23 of the abnormality detection device are operated due to other failure causes. L6 and L. The blinking status and the running/stopping status of the electric motor 14 operate in the same way as the failure of the grain circulation process described above, so a description thereof will be omitted. In short, the present invention is applicable to the grain circulation process of the grain dryer, the hot air temperature in the hot air chamber, the automatic fire extinguisher of the fire heat generator, the combustion state of the fire heat generator, the amount of grain fed in the grain feeding section of the elevator, the climate of drying wind, etc. When an abnormal change occurs, the motor is immediately stopped by a signal from the abnormality detection device, and the operation indicator lamp is extinguished.
Since the alarm lamps provided for each equipment section are configured to blink continuously, it is possible to clearly identify each faulty section and take immediate and appropriate measures.
