[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operating device for a grain dryer.

[0002]

2. Description of the Related Art Conventionally, grains stored in a grain storage chamber of a grain dryer are fed from the storage chamber to the grain drying chamber and circulated while flowing down. The burner is controlled by the operating device to burn and stop combustion at preset time intervals, hot air is generated during combustion from this burner, and the hot air and the outside air mix to form dry air. By passing through the drying chamber,
The grains flowing down in the drying chamber are exposed to the drying air and dried.

During the drying operation, the detected drying air temperature, the moisture content of the grain and the like are alternately displayed on the display section of the operating device, but the burner is burning or the combustion is stopped. Is not displayed. According to the above, for example, when the combustion of the burner of the dryer is stopped, a malfunction occurs in this burner, and it is distinguished whether the combustion of this burner is stopped or the combustion is stopped in the regular combustion control. Therefore, it is possible to easily distinguish between the malfunction stop and the combustion stop so that the operation can be facilitated and the work feeling can be improved.

[0004]

To this end, according to the present invention, the burner 3 is fed at a predetermined time interval while the grains are fed from the upper grain storage chamber 7 to the lower grain drying chamber 8 and circulated. While the combustion is stopped and the combustion is stopped, the dry air in which the hot air generated from the burner 3 and the outside air are mixed is ventilated to the drying chamber 8 to control the drying, and the starting operation is performed.
In the grain dryer provided with the operating device 14 for performing the stop operation, a control device 45 is provided for displaying on the display unit 43 of the operating device 14 that the burner 3 is in combustion and the combustion is not in operation. The operation unit of the grain dryer shall be configured.

Further, the burner 3 is displayed on the display unit 43 of the operating device 14.
The operation of the grain dryer, which is provided with a control device 45 for displaying the movement of the combustion of the fuel and the time elapsed during the combustion stop from the predetermined reference time of the setting and the movement of the setting to the predetermined reference time. The configuration of the operating device.

[0006]

The operation and effect of the present invention: The grains stored in the grain storage chamber 7 of the grain dryer are fed from the storage chamber 7 to the grain drying chamber 8 and circulated while flowing down by the operating device 14. The burner 3 is controlled to burn and stop burning at preset time intervals, hot air is generated from the burner 3 during burning,
The hot air and the outside air are mixed to become a dry air, and the dry air passes through the drying chamber 8, whereby the grains flowing down in the drying chamber 8 are exposed to the dry air and dried. .

During the drying operation, the control unit 45 controls the display unit 43 of the operating device 14 during burning of the burner 3.
For example, "ON" is displayed, and "OFF" is displayed while the combustion is stopped. Further, the detected dry air temperature, grain moisture value, etc. are also displayed. These ON-OFF, dry air temperature, grain moisture value, etc. are displayed alternately. Further, when the combustion is in progress, the control device 45 sequentially moves from the set predetermined reference time for changing from the combustion to the combustion stop, and the remaining time is sequentially displayed on the display unit 43 of the operating device 14 to stop the combustion. When it is in the middle, the movement from the combustion pause to the combustion is sequentially moved to the set predetermined reference time, and the remaining time is sequentially displayed on the display unit 43 of the operating device 14.

From the above, it is possible to easily distinguish whether the burner 3 is in a stopped state due to a malfunction or is in the combustion stop of the normal combustion control. Alternatively, the remaining combustion time, the remaining combustion stop time, and the like can be easily known, and the operation can be facilitated and the sense of security of work can be improved.
