Description

[Detailed description of the invention] Industrial applications The present invention relates to an operating device for a grain dryer.

Conventional technology Conventionally, the drying conditions of the dryer are set at setting 'A', the start/stop device is used to start, stop, etc. the dryer, the hot air temperature and grain moisture value of the dryer are operated. An operating device that displays a display device, etc., and a controller that has a control device that receives operation inputs of the setting device and the start/stop device of this operating device and controls the dryer are integrated. The dryer cannot be operated or monitored by removing it from the controller and moving it to a remote location. .

Problems to be Solved by the Invention By operating the setting device of the operating device to a predetermined position and operating the start/stop device according to the amount of grain to be dried, moisture value, etc., each of these operations is input to the control device. The input starts and controls the dryer,
Hot air is generated from the burner, and the grains circulating in the dryer are exposed to this hot air and dried.A moisture sensor detects the moisture value of the grains during this circulation drying, and this detected value and the moisture generated from the burner are In the operating device of the dryer, which displays the temperature of the hot air on a display device, the place where the dryer is installed and the drying work is performed is a workplace, and this drying work is often performed at night. At night, etc., the operating device including the setting device, the start/stop device, the display device, etc. is removed from the controller including the control device and moved to the living room where the operator is present, and the operating device and the controller are removed. The dryer can be connected so that the dryer can be operated and monitored in the living room, and at the same time, if the operator forgets to connect the controller, the dryer will automatically stop after a predetermined period of time has elapsed. This is intended to prevent the quality of grains from deteriorating during drying even if a problem occurs in the dryer while the connection is forgotten.

Means for Solving the Problems This invention provides a setting device (1) for setting the drying quality of the dryer based on the amount of grains to be dried, moisture value, etc., and operations such as starting and stopping the dryer. An operating device (4) having a start/stop device (2), a display device (3) for displaying the hot air temperature, grain moisture state, etc. in the operating state of the dryer, and the settings of this operating device (4). Device (1) and the start/stop I-
A controller (6) having a control device (5) that receives the operation input of (2) and controls the dryer is connected to the controller (6). Katsuko controller (
In contrast to 6), an operating device for a grain dryer is provided with a stop control device that automatically stops the drying operation of the dryer after a predetermined period of time when the operating device (4) is not connected. composition.

Effect of the Invention The operating device (4) and the controller (6) of the operating device are connected and the setting device (1) provided on the operating device (4) is set at a predetermined position depending on the amount of grain to be dried, moisture value, etc. By operating the start/stop device (2), each operation is input to the control device (5) of the controller (6), and this input causes the control device (5) to start the dryer. At the same time as the dryer is started, hot air is generated from the burner, and the grains circulating in the dryer are exposed to and dried, and the moisture value of the grains during this circulation drying is measured by a moisture sensor. detected,
This detected moisture value and the temperature of the hot air generated from the burner are detected, and the detected hot air temperature is alternately displayed on the display device (3) provided on the operating device (4), and the setting device (1) is operated. When the moisture sensor detects a grain moisture value that is the same as the set finishing target moisture value, drying of the grains is stopped.

When operating or monitoring the dryer from a remote location, the operating device (4) of the operating device is removed from the controller (6) and moved; 6
) and when changing the drying work conditions, operate the setting device (1), this operation will be input to the control device (5), and this input will cause the control device (5) to change the dryer. The temperature of the hot air generated from the burner is controlled, and the detected temperature of the hot air and the detected moisture value detected by the moisture sensor are alternately displayed on the display device (3).

Further, after moving the operating device (4) to a remote position, if the operating device (4) is not connected to the controller (6) for a predetermined period of time, the stop control device automatically controls the operation device (4). to automatically stop the dryer.

Effects of the Invention According to the present invention, the operating device (4) of the operating device of the dryer is formed to be detachable from the controller (6), so that the operating device (4) can be moved to a long distance position and operate the machine,
or monitoring can be carried out at the same time as this operator (
4) is not connected to the controller (6) for a predetermined period of time or more, the dryer will automatically stop, resulting in, for example, a malfunction in the fuel pump that supplies fuel to the burner during this drying operation, and this malfunction. Even if the temperature of the hot air generated from the burner rises abnormally due to the temperature increase, the temperature of the hot air that has risen abnormally will be displayed on the display device ( 3) is not displayed, so the operator cannot know the abnormally high hot air temperature. However, even if this situation occurs, the dryer will automatically stop after a predetermined period of time. The temperature of the grains during drying increases abnormally due to an abnormal -1- rise in the hot air temperature,
Due to this grain temperature abnormality 1-';;+, the grain moves toward the trunk side,
By automatically stopping the dryer after a predetermined period of time has elapsed, this occurrence on the shell side can be prevented.
