Description

[Detailed Description of the Invention] The present invention relates to a lighting device mounted on a mobile agricultural machine.

Conventionally, in mobile agricultural machinery used for rice planting, plowing, etc., the lighting system required for nighttime work is an assembly consisting of a lens attached to the front of a reflector plate with a built-in lamp, and this is attached to the bonnet. Alternatively, it was designed to protrude from or be installed inside the fuselage, but protruding items could hit crops and obstruct work or obstruct forward visibility. This causes inconveniences such as the need to provide storage space and mounting materials,
If this is installed inside the bonnet, the design of the bonnet is affected by the outline shape of the light assembly that houses it, making it impossible to freely set an elegant design.Furthermore, the lamp lead wire is wired from the hood to the fuselage, so
When opening and closing the bonnet, the lead wire had to be attached and detached, making the operation complicated and troublesome.

In view of the above-mentioned actual situation, the purpose of this invention is to improve this.The lighting device is divided into two parts, a reflector and an irradiation lens, and the irradiation lens is attached to the bonnet. The reflector is provided on the fuselage side, and the reflector is provided with a fixing support member for the bonnet so that it can be supported when the bonnet is closed, so that the bonnet can be freely formed into an elegant design, and The bonnet does not require a special supporting member, and a reflecting plate also serves as a supporting member.

To explain an embodiment in which the structure of the present invention is applied to a rice transplanter, 1 in the figure is the body frame of the rice transplanter, and an engine 2 is mounted on the front part of the body frame 1. A driving operation handle 3 is provided at the rear of the frame 1 and extends rearward and obliquely upward. Numeral 4 is a seedling mounting table, which is suspended from the operating handle 3, and 5 is a planting device, which is provided in front of the seedling placing table 4. Reference numeral 6 denotes traveling wheels supported by the ends of a transmission case 7 which protrudes from the body frame 1 to the left and right, so that they can swing up and down. Reference numeral 8 denotes a surface sliding body, which is attached to the fuselage frame 1 so as to be vertically movable.

Reference numeral 9 denotes a bonnet that covers the area from the engine 2 mounted on the front of the fuselage to the planting device 5 at the rear of the fuselage, and is made of synthetic resin. 10 is provided, and the rear portion is supported by a pivot pin 11 provided on the fuselage frame 1.
It is configured to be able to be opened and closed with 1 at the center.

2 is an enlarged view of the lighting device with the bonnet 9 closed, and the reflector 13 incorporating the lamp 12 is attached to the engine 2, and the bonnet 9 is fixed with fixing bolts 15 provided on the reflector 13. More specifically, the reflector 13 is box-shaped with a roughly U-shaped cross section, the inside of which is entirely plated, and is attached to the engine 2 with a bolt 14 with the opening facing forward. The rear of the lower side of the reflector 13 is curved, and a lamp socket 12a is provided on the curved surface so as to project upward, and the lamp 12 is supported by this. The lamp socket 12a is connected to a lead wire 12b that passes under the reflector 13. Reference numeral 13a denotes a mounting seat portion protruding upward from the lower edge of the reflector 13, and reference numeral 15 denotes a bonnet fixing bolt provided on the mounting seat portion 13a. The tip end of the bonnet 9 is placed on the mounting seat portion 13a and then fastened in place by the fixing bolt 15.

On the other hand, in the closed state, the bonnet 9 has an opening 9a in the portion facing the reflecting plate 13, and an irradiation lens 10 is attached to the front of the opening 9a with a bolt 10a. 9b is a lower edge portion 16 formed below the opening 9a of the bonnet 9;
is a lock washer 16b screwed onto the lower edge 9b,
A nut 1 screwed into the fixing bolt 15 in the center part
6a is welded.

The lamp 12 is made waterproof by a draining groove 9c provided on the bonnet 9 and a fitting between the protruding edge 9d similarly provided on the bonnet 9 and the concave edge 10b formed on the irradiation lens 10. ing. 17 is a snap switch for blinking the lamp 12;

In the embodiment of the present invention, the pivot pin 11 is provided at the rear end of the bonnet 9 so that the bonnet can be opened and closed using this pivot pin, but the rear end may be attached by any suitable fixing method. The length can also be set according to the functional design.

Furthermore, although the embodiments of the present invention have been described with respect to a rice transplanter, it goes without saying that the present invention may be used in other mobile agricultural machines.

As mentioned above, when closing the bonnet 9, the lower edge 9b of the bonnet tip is placed on the mounting seat 13a of the reflector 13, and the fixing bolt 15 is
If you turn the knob, the threaded part will be attached to the nut 16.
The bonnet 9 is fixed by screwing into the hole a. To open the bonnet 9, loosen the fixing bolt 19 and lift the tip of the bonnet 9 in the opposite order to the closing procedure.
It opens upward from the center to open both the lighting system section and the engine section, making it easy to inspect and maintain them.

In the present invention, as mentioned above, the illumination device has a structure in which the reflector and the illumination lens are separate bodies, and the illumination lens is attached to the bonnet and the reflector is attached to the aircraft body. Because of this, the irradiation lens can be formed as a single unit to match the shape of the bonnet, and the bonnet as a whole can have an elegant design that is integrated with the irradiation lens.When the bonnet is closed, the irradiation lens is Since the lens and the reflector face each other, it is of course possible to illuminate the target direction reliably, and since the reflector is provided with a fixed support part for the bonnet, it can be constructed simply and at low cost without providing a separate support member. Since the lamp is attached to the fuselage side, its lead wire does not get in the way when opening and closing the bonnet, and when inspecting or replacing the lamp or engine plug, the length of the bonnet can be easily opened. It can be easily detached from the fuselage, and the engine and fuselage transmission parts can be conveniently maintained.
