SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances in order to solve these problems, and is an operation panel for a mobile agricultural machine in which a plurality of monitor lamps are incorporated. It is characterized in that a monitor lamp housing portion for housing a plurality of monitor lamps in parallel is integrally formed in the panel body of the operation panel for the mobile agricultural machine. In other words, the monitor lamp housing is separate from the panel body, and the number of parts and assembly steps are reduced compared to the conventional one in which the back surface of the panel body was screwed.
The cost can be reduced. In addition, the invention is characterized in that a plurality of lamp accommodating chambers formed in the monitor lamp accommodating portion are respectively provided with heat dissipation slits. In this case, since the heat generated by the monitor lamp can be dissipated through the slit, it is possible to eliminate the inconvenience that the monitor lamp housing portion is thermally deformed by the heat trapped in the lamp housing chamber. Further, the present invention is characterized in that the heat radiation slits of the respective lamp housing chambers are alternately formed on the two opposite outer surfaces of the monitor lamp housing portion. In this case, the light of the monitor lamp that leaks from the heat radiation slit is less likely to enter the adjacent lamp housing chamber, so that erroneous display due to the incident light can be prevented.

In the drawings, reference numeral 1 is a traveling machine body of a passenger rice transplanter, and the traveling machine body 1 includes a machine body frame 2, an engine (not shown) mounted in a front portion of the machine body frame 2, and power of the engine. A transmission 3 that shifts gears, wheels 4 that are driven by traveling power output from the transmission 3, a driver seat 5 provided at the rear of the machine body, and a steering wheel 6 provided in front of the driver seat 5.
And an operation panel 7 provided below the steering wheel 6, and the planting work section 11 is connected to the rear part of the machine body via an elevating link mechanism 11a.

The operation panel 7 comprises a panel body 8 integrally molded of resin, a plurality of monitor lamps L, and a single combination switch 9. The combination switch 9 is an alarm stop switch (non-residual switch) 9a for temporarily stopping an alarm such as a seedling supply alarm.
And a light switch 9b for turning on / off the headlight, and a work changeover switch (residual switch) 9c for turning on / off the alarm circuit, which are attached to the left end portion of the operation panel 7. . That is, the switches 9a, which are conventionally arranged in a distributed manner on the left and right sides of the operation panel 7,
Since 9c is integrated with the combination switch 9, the operability of the switches 9a to 9c can be improved,
Moreover, since the light switch 9b for turning on / off the headlight and the work changeover switch 9c for turning on / off the alarm circuit are functionally independent, at the time of work (alarm circuit is in an ON state).
It becomes possible to light the headlight also in.

A plurality of monitor lamps L are stored in parallel in the monitor lamp storage portion 8a. Monitor lamp storage 8
A is a horizontally long bottomed box shape as a whole, and the inside thereof is partitioned by a plurality of partition portions 8b to form a plurality of lamp storage chambers 8c. The conventional monitor lamp housing portion is formed separately from the panel body 8 and is attached to the back surface of the panel body 8 via a screw, but the monitor lamp housing portion 8a according to the embodiment of the present invention is the panel body 8. Is integrally formed on the back surface of the. As a result, the number of parts and the number of assembling steps are reduced as compared with the conventional one, and the cost can be reduced.
A lamp mounting hole 8d for mounting the monitor lamp L in the lamp housing chamber 8c is formed at the bottom of each lamp housing chamber 8c.

A monitor cover 10 is attached to the front side of the monitor lamp housing portion 8a of the panel body 8. The monitor cover 10 is a plate-shaped or film-shaped member made of a translucent resin material, and its front surface (or back surface).
A monitor item such as a fertilizer warning, a fertilizer stop warning, a fertilizer clogging warning, and a seedling supply warning is printed as characters or symbols corresponding to each monitor lamp position. The monitor cover 10 attached to the panel body 8 covers the front opening of each lamp housing chamber 8c of the monitor lamp housing portion 8a, and the monitor items are lit and displayed according to the lighting of each monitor lamp L. In addition, the monitor cover 1 in the panel body 8
A concave portion 8e corresponding to the thickness dimension of the monitor cover 10 is formed at the attachment portion of 0, and the monitor cover 10 and the panel body 8 are substantially flush with each other by attaching the monitor cover 10 to the concave portion 8e. As a result, the monitor cover 10 is prevented from coming off.

A plurality of slits 8f communicating with the respective lamp storage chambers 8c are formed on the outer surface of the monitor lamp storage portion 8a. The slit 8f is formed in the front-rear direction, and functions as a heat dissipation hole of the monitor lamp L by communicating with each lamp housing chamber 8c. As a result, it is possible to eliminate inconveniences such as the monitor lamp housing portion 8a being thermally deformed by the heat trapped in the lamp housing chamber 8c and the monitor cover 10 being easily peeled off.

The slits 8f of the lamp housing chambers 8c are alternately formed on two opposite outer surfaces (upper surface and lower surface) of the monitor lamp housing portion 8a. That is, the slits 8f of the adjacent lamp storage chambers 8c are not directed in the same direction, and as a result, the light of the monitor lamp L leaking from the slits 8f is less likely to enter the adjacent lamp storage chambers 8c, and is incident. False display due to light is prevented.

Further, ribs 8g are formed on the upper and lower surfaces of the monitor lamp housing portion 8a. The rib 8g is formed in the front-rear direction between the slits 8f and functions as a light shielding wall for the lamp light leaking from the slits 8f.
This makes it possible to further reduce the possibility that the lamp light leaked from the slit 8f will enter the other lamp housing chamber 8c.

In the construction as described above, the traveling machine body 1 is provided with an operation panel 7 in which a plurality of monitor lamps L are incorporated, and the panel body 8 of the operation panel 7 is provided with the plurality of monitor lamps L. A monitor lamp storage portion 8a that is stored in parallel is integrally formed. Therefore, the number of parts and the number of assembling steps can be reduced and the cost can be reduced as compared with the conventional one in which the monitor lamp housing portion 8a is separate from the panel body 8.

Further, since the plurality of lamp housing chambers 8c formed in the monitor lamp housing portion 8a are respectively provided with heat radiation slits 8f, the heat of the monitor lamp L is radiated through the slits 8f. As a result, inconveniences such as the monitor lamp housing 8a being thermally deformed by the heat trapped in the lamp housing 8c and the monitor cover 10 peeling off can be eliminated.

Further, since the slits 8f are alternately formed on the two opposite outer surfaces of the monitor lamp housing portion 8a, the light of the monitor lamp L leaking from the slits 8f is
It becomes difficult for light to enter the adjacent lamp housing chambers 8c, and erroneous display due to incident light can be prevented.

Further, since the plurality of lamp storage chambers 8c are covered by the single monitor cover 10, the number of parts can be reduced, and the monitor cover 10 is provided in the panel body 8 as well.
Since it is affixed to, it can also contribute to simplification of the assembly work.
