Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for displaying a scheduled drying time of a grain dryer. 2. Description of the Related Art Conventionally, grains that are fed from a grain storage chamber to a grain drying chamber are dried by being exposed to drying air, and the moisture of the grains during drying is removed at predetermined time intervals. Each time it is detected by the moisture sensor. On the surface of the operating device for operation, there is a display unit that displays the drying air temperature, grain moisture and expected drying time, etc., and a drying setting switch that sets the grain type and the drying speed such as slow, normal, and fast drying. , A moisture setting switch for setting the finishing target moisture, a setting switch for setting the amount of grain to be stuffed, a start switch for starting each work of stuffing, drying and discharging, and a stop switch for performing a stop operation are provided. The operation of the detected grain moisture, the set finish target moisture, and the scheduled drying time until the end of drying by operating the drying setting switch and the display of the computed value on the display unit are performed each time the grain moisture is detected. There is . By the way, when the finish target moisture is changed and set by the operation of the moisture setting switch during the drying, or by the operation of the drying setting switch, the grain type and the drying speed are changed.
When the degree is set to change, the calculation of the scheduled drying time until the end of drying is performed after the detection of the grain moisture to be detected next time,
In this display method, the display is changed to the calculated value. [0003] [0004] [0005] The object of the invention is to be Solved in a dry work
Since moisture detection is performed at predetermined time intervals,
Has no moisture data.
The next time the detection of the next grain moisture, drying
The set time (remaining time) is calculated, and the calculated drying
The fixed time (remaining time) will be changed on the display.
You. Therefore, the next time display of the moisture detection to different dry scheduled time (remaining time) will be followed, but it is not possible to notify immediately to the operator to change the time, trying to solve this problem
Is what you do. According to the present invention, there is provided a method of drying a grain by feeding dry grains from an upper grain storage chamber 7 to a lower grain drying chamber 8 while causing the grains to flow down . Grain water
A moisture sensor 2 for detecting the minute
It is configured to measure the grain moisture, and the moisture setting switch 33 is operated.
Whether or not the finishing target moisture set in advance
Configured to automatically stop each operation part based on the judgment and detected
Grain moisture, set finish target moisture and drying in the drying process
By calculating the expected drying time until the end of drying by the speed,
Together, the time is displayed on the display unit 43 by the grain dryer.
During the drying of the grain, the moisture setting switch 33 is operated.
The target moisture is changed or set
Grain type or drying speed by operating the setting switch 35
When the value has been changed, the drying is terminated based on the moisture value immediately before the change.
Calculates the expected drying time until completion and changes the display to this calculated value
Display of the scheduled drying time of the grain dryer characterized by performing
The configuration of the device . When the drying operation of the grain is started by the grain dryer, various items are set by operating the moisture setting switch 33 and the drying setting switch 35 of the operating device 14, and the like. By operating the start switch 31 for starting the drying operation, the dryer, the moisture sensor 2 and the like are started. The grains stored in the grain storage chamber 7 of the dryer are fed out of the storage chamber 7 and into the grain drying chamber 8 while being dried under the action of drying air. The moisture of the grain during drying is detected by the moisture sensor 2 and displayed on the display unit 43, and the detected target moisture and the finish target moisture set by operating the moisture setting switch 33 and the operation of the drying setting switch 35 are operated. The estimated drying time (remaining time) is calculated on the basis of the grain type and the drying speed set in the above, and the calculated expected drying time (remaining time) is displayed on the display unit 43. During the drying operation, the moisture setting switch 33
Is operated to change the finish target moisture, or the drying setting switch 35 is operated to change the grain type and the drying.
When the speed is changed and set, the scheduled drying time (remaining time) is immediately calculated based on the changed setting item and the grain moisture detected immediately before, and the calculated scheduled drying time is calculated. The time (remaining time) is displayed on the display unit 43. According to the present invention, when the target moisture content or the grain type and the drying speed are changed during the drying operation, the expected drying time (remaining time) is immediately calculated,
By changing the display to the calculated value, the operator can quickly change the above items and set the expected drying time (remaining time)
