JP 2001-251939 A

  However, since the information display device displays a lot of information on the monitor display unit, unnecessary information is simultaneously displayed depending on the work, and it is necessary to select information from the many display items. In particular, there has been a problem that a response delay occurs when the situation changes.

  The problem to be solved is that the combine information display device can improve the workability as a whole by each accurate work without causing a delay in response to the situation change in accordance with the work process by the combine. Is to provide.

  The invention according to claim 1 is provided with a monitor display unit 11 capable of switching a display screen by a plurality of switching switches. The monitor display unit 11 has a working state based on at least an engine load, a grain storage amount, and a vehicle speed. In the combine information display device having the normal screen 21 to be displayed, the monitor display unit 11 is additionally provided with a vehicle height display screen 22 for displaying the vehicle height adjustment state, and the normal switch 21 is operated by operating a predetermined switching switch 15. A feature is that the screen can be switched from the screen 21 to the vehicle height display screen 22.

  On the monitor display unit 11, the engine load, the grain storage amount, and the vehicle speed are displayed on the normal screen 21, and the vehicle height adjustment state is displayed by switching to the vehicle height display screen 22 by operating a predetermined switching switch 15. The

  According to a second aspect of the present invention, in the configuration of the first aspect, the monitor display unit 11 includes a maintenance mode screen 23 for displaying maintenance information. The maintenance mode screen 23 is switched from the normal screen 21 to the switching mode. The screen can be switched by operating the switch 15, and the screen can be switched to a maintenance content screen 31a for displaying items requiring maintenance by a second switching switch 16 provided separately. The maintenance screen is switched from the normal screen to the maintenance mode screen 23 by operating the first switching switch 15, and the necessary maintenance items are displayed by switching the maintenance content screen 31 a by operating the second switching switch 16.

  The monitor display unit 11 of the combine information display device according to claim 1 does not require the display of the vehicle height adjustment state, and the normal screen 21 displaying the engine load, the grain storage amount, and the vehicle speed displays the situation according to necessary information. It is possible to efficiently perform the cutting operation while ensuring the change adaptability. When the vehicle height adjustment is necessary, the vehicle is displayed by switching to the vehicle height display screen 22 by operating a predetermined switch 15 for switching. Accurate and quick vehicle height adjustment according to the state of the field can be performed while checking the high adjustment status, so that the workability of the entire cutting operation including the vehicle height adjustment can be improved.

  According to the combine information display device of claim 2, the maintenance content screen 31 a can be switched by operating the second switch 16 in combination with the above-described effect of claim 1. Therefore, based on the displayed maintenance items, Appropriate maintenance can be handled.

Embodiments specifically configured based on the above technical idea will be described below with reference to the drawings.
FIG. 1 is a sketch of a combine information display apparatus according to the present invention and a screen example (? 1).
In the information display device 1, a monitor display unit 11 and an engine tachometer 12 using a liquid crystal display or the like are arranged in two vertical stages at the center position, and push button type left and right blinker switches 13L and 13R are arranged symmetrically on both sides thereof. In addition, a switch such as a headlamp forward switch 14F, a headlamp downward switch 14D, a changeover switch 15, a horn switch 16 and the like are arranged, and a monitor control unit (not shown) is provided to form a single unit.

  The monitor display unit 11 displays information necessary for the cutting work such as the remaining fuel amount 21a, the engine load 21b, the Glen tank storage amount 21c, etc. as the normal screen 21 for the work, as well as the changeover switch 15, the horn switch 16, Various information is displayed for each system according to the combination of the winker switches 13L and 13R as screen switching switches.

  As for the normal screen 21, by operating the changeover switch 15 as the first switch, a vehicle height display screen 22 for graphically displaying the vehicle height adjustment state of the fuselage (in the example shown, the highest position display), as an entrance for maintenance information display The maintenance mode screen 23 can be sequentially switched to the normal screen 21 through each screen.

  The information display device 1 appropriately displays the operation status / operation information of the work implement on the monitor display unit 11, and operates the changeover switch 15 as necessary to operate a normal screen 21, a vehicle height display screen 22, a maintenance mode screen. 23 can be sequentially switched. Therefore, the normal screen 21 displays the engine load, the amount of stored grain, and the vehicle speed without requiring the display of the vehicle height adjustment state, etc., so that efficient harvesting is ensured while ensuring the situation change correspondence according to necessary information. It is possible to proceed with the work, and when the vehicle height adjustment is necessary, the vehicle height adjustment screen is switched to the vehicle height display screen 22 by operating a predetermined changeover switch, and the vehicle height adjustment state is confirmed while the vehicle height is adjusted. Since accurate and quick vehicle height adjustment is possible, the workability of the entire cutting operation including vehicle height adjustment can be improved.

(Maintenance mode)
The monitor display unit 11 displays a maintenance guidance screen 20 when a predetermined maintenance time is reached in the operation of the combine, and is selectively displayed by the changeover switch 15 as shown in a screen example (2) in FIG. By operating the horn switch 16 serving as the second switching switch from the maintenance mode screen 23, specific maintenance items are displayed from the maintenance information screen 31 on the maintenance content screen 31a ("50 hours maintenance guide" in the figure). .

  The information display device 1 appropriately displays the operation status / operation information of the work implement by the monitor display unit 11, and sequentially switches to the normal screen 21, the vehicle height display screen 22, and the maintenance mode screen 23 by operating the changeover switch 15. In addition, since the maintenance is guided every maintenance time, the screen can be switched to check the maintenance content on the maintenance content screen 31a.

  Further, as shown in the screen example (3) of FIG. 3, in the maintenance mode screen 23, in order to confirm the contents of each maintenance, a “maintenance information” screen 31, a “daily inspection” screen 32, and “store” The “inspection” screen 33 is displayed so as to be switchable, and the “mode end” screen 34 can be returned to the normal screen 21 by operating the changeover switch 15.
