At the front of the driver's seat 6, a steering handle 35 and an instrument panel 36 are provided.
A liquid crystal display device 37 for displaying various alarms and information messages is provided along with various switches.

The following are examples of alarm items to be displayed on the display device 37. (A) A seedling warning issued when the remaining amount of seedlings on the seedling holder 16 is low. (B) An alarm indicating that the fertilizer has run out when the remaining amount of fertilizer in the fertilizer hopper 25 is low. (C) A fertilizer clogging alarm issued when fertilizer clogging occurs in the groove generator 31. (D) A warning to forget to put in the planting clutch, which is issued when the work traveling is performed with the planting clutch 14 turned off.

Is issued. The remaining amount of fuel is measured by a well-known electric fuel sensor s8, and the occurrence of overheating is detected by a temperature sensor s9 provided at an appropriate position of the engine 8.

When an alarm cause occurs in any of the above-mentioned alarm items (A) to (H), the control device 38 which controls the operation of the display device 37 transmits the alarm to the display device 37 so that an alarm display corresponding to each item is made. Sensors s1 to s9 are connected.

As shown in the flowchart of FIG. 9, the control device 37 is programmed with a normal alarm mode for executing normal alarm control and a priority alarm mode for executing priority alarm control. In the normal alarm mode, alarm messages corresponding to each of the alarm items in which the alarm factors have occurred are sequentially displayed in a predetermined order for a predetermined time (for example, several seconds). In the priority alarm mode, when an alarm cause occurs in an alarm item specified in advance in the alarm item group, an alarm message corresponding to this alarm item is given priority over an alarm message corresponding to another alarm item. And display
The priority alarm display is continued until the alarm factor of the specified alarm item is eliminated.

Here, out of the warning items (A) to (H), the warning (A) for running out of seedling and the warning (B) for running out of fertilizer are prioritized warning items. If it is detected that the remaining amount is less than the setting or that the remaining amount of fertilizer is less than the setting, other alarm factors (C) to (H) have occurred. The priority warning mode is also set, and a warning message prompting the supply of seedlings to the seedling rest 16 and the supply of fertilizer to the fertilizer hopper 25 is continuously displayed on the display device 37. Then, the alarm display is continued until seedling replenishment or fertilizer replenishment is performed and the alarm factor is eliminated (see flowcharts in FIGS. 9 and 10). In this priority alarm mode, the displayed message itself is made to blink at an appropriate cycle, thereby attracting the driver's attention.

Further, the instrument panel 36 is provided with a push-button type alarm release switch 39. Even when the alarm display in the priority alarm mode is continuously performed, the alarm release switch 39 is consciously operated. By pressing this button, it is possible to switch to the normal alarm mode. As a result, it is possible to know the status of other alarm items while sufficiently recognizing the contents of the alarm display in the priority alarm mode.

In addition, at the time when the work travel is first started, even if an alarm cause is generated for the specified alarm item, the control device keeps the normal travel until the work travel of one stroke is completed. It is programmed to execute the alarm display in the alarm mode.

For example, in the rice transplanting operation, after performing reciprocal planting, the remaining headland along the ridge is finally planted so as to make a round in the field, and is provided in one place in the field. After getting in from the entrance and planting work,
At the beginning of the work, introduce a process that moves the seedling planting equipment down to the field scene and moves along the ridge without planting, that is, an empty planting process, because it goes out from the same entrance and exit. Work styles are often adopted. In this case, if seedlings are not mounted on the seedling planting equipment, this is normally given a higher priority, and the warning will not be displayed even if other warning items cause a warning. Since the control device 38 is programmed as described above, the priority warning mode is ignored and the warning display in the normal warning mode is executed until the empty planting process is completed. If a warning factor has occurred in a normal warning item, such as forgetting to draw a line marker, this will be sequentially displayed. And
If the empty planting process is completed and the process proceeds to the normal planting process, the priority warning mode returns to the warning display control in which the priority is given to the normal warning mode, and the reduction of the consumption material is displayed with priority. It should be noted that the end of the empty planting process can be recognized by detecting that the seedling planting apparatus 5 has been lifted and operated by an artificial command.

A keyboard 40 including a numeric keypad can be connected to the control device 38 as work condition input means. When this keyboard 40 is connected,
Calculate the amount of seedlings and the amount of seedlings to be planted in a given area with the determined amount of seedlings, and calculate the amount of fertilizer payout when performing rice transplanting and fertilizing work at the same time. Can be numerically displayed on the screen of the display device 37.

For example, when a predetermined number of mat-shaped seedlings are applied to one field, the field area, the seedling amount, the number of planting lines in one pass of the rice transplanter, and the number of plants can be input. 1
The amount of seedlings collected can be calculated, and the amount of lateral or vertical feed of the seedling gantry 16 can be determined and numerically displayed on the display device 37. Further, if the horizontal feed amount and the vertical feed amount of the seedling placing table 16 are determined, the interval between the plants can be calculated and displayed. Or, conversely, the field area, the number of planting lines in one stroke of the rice transplanter,
By inputting the amount of seedlings collected per plant, etc., the amount of seedlings (the number of mat-shaped seedlings) required in this field can be calculated and displayed. Further, by inputting the work conditions such as the area of the field, the number of planting lines in one stroke of the rice transplanter, the stock, the amount of fertilizer supply per unit area, the work traveling speed, and the like, the amount of fertilizer dispensed is calculated. The results can be displayed.

[Another Embodiment] As a means for promptly recognizing the warning display of the priority warning item to the driver, in addition to the blinking of the warning message itself as described above, the entire background of the display device 37 may be blinked. Also. When a color liquid crystal can be used, the recognition is further facilitated by making the display color different between the priority alarm mode and the normal alarm mode. When the maximum execution time of the normal alarm control in the normal alarm mode is short, as described above, the priority alarm control in the priority alarm mode and the normal alarm control in the normal alarm mode may be sequentially executed. In the case where the maximum execution time of the normal alarm control is relatively long, the priority alarm control in the priority alarm mode may be executed by interrupting the normal alarm control. The display device 37 may display not only an alarm display, but also an engine speed, an engine operating time, and the like, so as to exhibit a function as a tachometer or an hour meter. Also,
It can also be used for displaying various information such as displaying a handling message of each part at the time of starting the engine and displaying a treatment when a trouble occurs. It is also possible to perform the control by omitting the recognition of the empty planting process at the start of the work.
