An upper conveyor 12 for grain filling is provided at the top inside.

On the outer surface of the machine body 1, an elevator 3 is erected on the front side, the bottom of which is connected to the end of the lower conveyor 11 in the transport direction, and the discharge formed on the top of the elevator 3 The tubular portion 30 is switchably connected to the discharge gutter 31 and the start end of the upper conveyor 12 in the transport direction, and the grains discharged by the lower conveyor 11 are transferred to the storage section W by the elevator 3, the upper conveyor 12, and the like. Allow the return circulation to take place.

On the outer surface of the machine body 1, a hot air generator 4 for generating hot air for feeding grains passing through the downflow path 20 of the drying section Y is provided on the front side in parallel with the elevator 3.
And the outlet of the hot air is communicated with the air guide passage 21, and an exhaust duct 24 communicating with the exhaust passage 22 of the drying unit Y is provided on the rear surface side of the body 1. Connect the suction side.

[0005] Further, on the outer surface of the machine body 1, each of the above-described lower conveyor 11, the elevator 3, the upper conveyor 12, and other operating parts for transporting the grains, and a rotary shutter 23 for feeding out the grains.
And a control box 6 for controlling the operation of the hot air generator 4 and the blower 5 for feeding the hot air generated thereby to the downflow path 20.

The control box 6 has an operation panel 6a provided on the front side of the control box 6 and a screen display a for displaying characters, numerals, pictures and the like freely on a display screen of a liquid crystal panel, A display operation device 7 in combination with switches b... Of a touch operation arranged and displayed on the display screen in a matrix is incorporated so as to control and operate a controller provided in the control box 6, and the display thereof is performed. The screen displaying the work items and condition items for controlling the operation of the grain dryer A, the monitoring items, and the switches b... For selecting and setting them is sequentially switched on the screen as shown in FIG. It is displayed.

When the grain is dried, a power switch S provided on the operation panel 6a is turned on to first display the grain on the display screen of the screen display a as shown in FIG. In the first screen (NO1) that is displayed,
The operation to be performed is selected and instructed by operating the switches b... In which the control contents are displayed in characters.

Here, for example, it is assumed that a drying operation is to be performed, and a switch "b" indicating "dry" is operated, and after the selection instruction is completed, the screen is displayed by operating the switch "b" indicating confirmation. Screen (NO2),
On the screen (NO2), the selection and setting of the hot air temperature is performed by operating the switches b... With the respective displays. When the operation is completed, the third screen (NO3) is operated by the operation of the switch b with the confirmation display. ), And select / instruct the grain on the screen (NO3), and then switch to the fourth screen (NO4) by operating the confirmation switch b.
To determine the finish moisture, and then perform the same operation on the fifth screen (N
O5), the drying time is set on the screen (NO5), and the various conditions of the drying operation are set based on these settings, and the respective operating units of the grain dryer A are controlled in accordance with the conditions. When the setting of these conditions is completed, each operating unit of the grain dryer A is driven to start the grain drying operation.

The screen display a provided on the front of the control box 6 has a screen displayed on its display screen, for example, at the right shoulder of the first screen (NO1). By the touch operation of the switch SW, the hidden screen that is not normally displayed is sequentially switched and displayed.

The hidden screen includes a customization screen m for setting only the condition items desired by the user as shown in FIGS. 4 and 5, and a grain dryer A as shown in FIG. Prior to use, a burner check screen n for checking the output and input of the ignition rod, fuel pump, cds, etc. of the burner of the hot air generator 4, and the motors of the respective operating units for transporting the grains as shown in FIG. The motor check screen o for checking the operation of the motor and the like of the blower 5 and, as shown in FIGS. 8 to 10, the operation of the switches b...

Regarding the items to be set in each of the skipped screens, the non-volatile memory in the CPU board keeps storing the contents set in the last drying operation even after the power of the control panel 2 is turned off. As a result, the same setting content as that of the previous drying operation is maintained, and when the operation selecting switch b is pressed, the drying operation is immediately started with the control content.

[0013]

As described above, the conventional circulation type grain dryer A uses the display operation device 7 provided on the operation panel 6a on the front surface of the control box 6 provided on the outer surface of the machine body 1 thereof. The screens are sequentially switched and displayed on the display screen of the screen display a, and the type of work, the temperature of hot air, and the type of grain to be dried are operated by touching each of the switches b displayed on the screens. By setting condition items such as finish moisture and drying time, and controlling the operation of each operating unit of the grain dryer A so as to comply with the conditions, the operation is started by starting the operation of the grain dryer A. In addition, the drying operation by the grain dryer A can be performed by automatic control in a state adapted to the properties of the grain to be dried.

However, during the drying operation,
For example, in order to monitor and check the screens of NO6-2, NO6-3, NO6-4, and NO7 in FIG. 3, go to the workplace where the grain dryer A is installed, A predetermined screen must be called up by operating the screen display a provided in the control box 6 provided in the machine body 1, and monitoring and confirmation must be performed on the screen, which is inconvenient when the workplace is far from home. There's a problem.

[0015] Furthermore, the same applies to the case where it is necessary to change the working conditions during the drying operation, and there is the inconvenience of having to go to the place where the grain dryer A is installed.

In this case, a remote controller constructed in the same manner as the display operation device 7 attached to the control box 6 provided in the grain dryer A is provided on the house side.
By doing so, it is only necessary to be able to remotely control and monitor the operation of the grain dryer A from the purlin / dwelling side.
