Further, it cannot be used in a place where the wireless Internet cannot be used, and there is a possibility that it cannot be used due to a communication failure caused by the Internet service provider side. Furthermore, since the display means is a portable terminal for possession, there is a risk of loss.

The problem with the rotating lamp and buzzer that informs the abnormal operation of the grain dryer is that it is impossible to confirm the detailed operation status such as the temperature of hot air blown into the grain dryer and the condition of the grain to be dried.
In addition, when configured to notify the abnormal operation of the grain dryer with a buzzer, it will be separated from the grain dryer due to the noise generated by other devices operating around the grain dryer or around the worker. There was a possibility that the worker in the place did not notice the sound of the buzzer.

  Therefore, the present invention solves the above-mentioned problems, and is capable of confirming the details of the operating condition or the condition of the dried grains circulating inside at various locations away from the grain dryer by simple means. It is an object to provide a machine.

  As a result of various studies to solve the above problems, the inventor of the present invention has a structure in which a grain dryer widely used is several meters in size and several tens of meters in large size. Because it has high height and excellent visibility from a remote place, a light source is installed on it, and the color of the irradiation light or the lighting or flashing pattern is circulated and flown through the operation state of the grain dryer or inside The present inventors have found that the above problem can be solved by associating with the grain state, and have completed the present invention.

That is, in order to solve the above problems, the present invention includes a grain storage tank in the upper stage of the dryer main body, a ventilation drying unit in the middle stage, and a grain take-out tank in the lower stage, and the grains stored in the grain storage tank. In the grain dryer that dries in the ventilation drying unit while circulating and flowing in the passage of the ventilation drying unit, the grain take-out tank, and the grain storage tank, the light source is separated from the grain dryer. with installed so as to be seen at the location, in accordance with the operation form status of the grain dryer, characterized in that the irradiation can configure different colors of light, or lighting or flickering pattern different light, grain dryer , To adopt.

  ADVANTAGE OF THE INVENTION According to this invention, the grain dryer which can confirm the detail of the driving | running condition from the distant place or the state of the to-be-dried grain circulating through the inside by a simple means can be provided.
