Description

[Detailed description of the invention] The present invention relates to a headlamp device installed on the front side of an agricultural machine.In particular, the inside of the lamp cover has a sealed structure to prevent rainwater and dirt from entering the lamp cover, and to prevent the lamp from entering the lamp cover. This invention relates to a headlamp device in which a lens provided at the front part of a cover is expanded to the side, and color-coded blinkers are provided on both sides to ensure work safety.

Unlike passenger cars, agricultural machinery such as tillers and tillers work with soil, grains, culms, straw, plants, etc.
Headlamps used for agricultural machinery should be sealed, as they are operated under adverse conditions such as being covered with muddy water in rice fields.However, as shown in Figure 1, conventional headlamps are A lamp cover 4 fixed to mounting plates 2, 2' surrounding the tank 1 by bolts 3°3' has an insertion window 7 in the center of the front part 5 for inserting a lamp 6, and a bottom plate 8 has an insertion window 7 for inserting a lamp 6. A cord hole 13 is bored through which a cord 11 for connecting the plug 9 to the lamp terminal 10 is inserted through a rubber ring 12.
It is fixed to the bracket 15 by a bolt 18 inserted into a notch 17 provided at the tip 16 of the bracket 15, which is attached to the lamp mounting plates 2, 2' housed in the lamp mounting plate 4 by means not shown.

In such a conventional lamp device, the lamp cover 4 and the lamp 6 are attached separately, so the lamp 6
A gap 19 inevitably exists between the lamp cover 4 and the lamp cover 4, and from this gap 19, dirt, grains, culms, dust, etc.
Water droplets may enter and damage the lamp terminal 10 or may accumulate on the bottom 20 of the lamp cover 4 and cause the lamp cover 4 and the cord 1 to be damaged.
1. This causes troubles such as corrosion of the mounting plate 2, and the need for brackets 15 and bolts 18, which causes an increase in manufacturing costs.For this reason, it is necessary to fit rubber or the like into the gap 19. Measures have been taken to prevent the intrusion of dirt, sand, etc., but in this case, not only does this increase the cost due to an increase in the number of parts such as rubber materials, but also
Rubber etc. deteriorate quickly due to exposure to sunlight, etc. and requires time and effort to be replaced.

Further, in the lamp device shown in FIG. 1, the lens 6' provided on the front of the lamp 6 is provided only on the front of the lamp cover 4, and no blinker for indicating left turn or right turn can be provided. As a result, work safety was compromised.

The present invention aims to eliminate the drawbacks and problems of conventional lamp devices as described above, and is designed to provide a lamp device that is a sealed type, has a simple structure, can be manufactured at low cost, and is also equipped with a blinker. The headlamp reflector and lamp mounting seat are integrally formed on the front of the lamp cover that is attached to the front of the fuel tank, and the turn signal reflector and lamp mounting seat are integrally formed on the left and right sides of the lamp cover. At the same time, the lens attached to cover the entire reflector of the headlamp includes a side surface portion that is bent rearward from both left and right ends of the lens along the outer surface of the left and right side plates;
There is provided a headlamp device for an internal combustion engine installed in agricultural work, characterized in that blinker lenses are formed continuously and integrally with blinker lenses positioned at the rear of each side surface portion and covering the reflectors of the blinkers.

Next, an embodiment will be described with reference to the accompanying drawings starting from FIG.

FIG. 2 is a perspective view of a lamp device according to one embodiment;
The figure is a cross-sectional view of the lamp device, and FIG. 4 is a side view of the entire internal combustion engine to which the lamp device is attached.

As is clear from the figure, the lamp cover 22 provided on the front side of the fuel tank 21 has an upper plate 24 which is an extension of the cover 23 of the fuel tank 21. Lower plate 25 and left and right side plates 2
6.27 constitutes four sides, top, bottom, left and right, and the front end 28 of the top plate 24 and the front end 2 of the left and right side plates 26 and 27.
9, 30 and the front end 31 of the lower plate toward the inner space 32 of the lamp cover 22 and integrally formed with a reflecting plate 33. It is provided with a lamp mounting seat 35 that is bent to form a lamp mounting hole 34, and the left and right side plates 2
At 6.27, there is a blinker located slightly below it.
The reflecting plates 42 a, 43 a of 42 and 43 and the lamp mounting seats 42 b, 43 b are integrally formed, and the mounting seat 4
Lamp bulbs 42C and 43c are attached to 2b and 43b, respectively.

Note that the position and inclination of the lamp mounting seat 35 of the headlamp are determined so that the lamp bulb 36 is located near the focal point of the reflector plate 33, but if a larger amount of light is required, the lamp mounting seat 35 may be It is also possible to arrange a plurality of seats 35 on the reflector plate 33 and attach a plurality of lamp bulbs 36.

As mentioned above, the headlamp and blinker reflector 33
．． On the front surface of the lamp cover 22 integrally provided with 42 a and 43 a, a lens 37 that covers the entire reflector 33 of the headlamp is attached to the periphery of the reflector 33, that is, the front end 28 of the upper plate 24, and the left and right side plates. 26. Front end 29 of 27
, 30 and the front end 31 of the lower plate 25, the lens 37 and each front end 28, 29, 30.3
1, and the lens 37 has a side surface portion 40 bent rearward from both left and right end portions 38.39 of the lens 37 along the outer surfaces of the left and right side plates 26.27.
．． 41 and the color-coded reflectors 42a, 4 of the blinkers 42, 43 located behind the side surface 40.41.
Turn signal lenses 52 and 53 that cover 3a are continuously and integrally molded.

The lamp cover 22, which has the lamp bulb 36 and the reflector 33 built into the inner space 32 and is shielded from the outside by the waist lens 37, is mounted on the front surface of the fuel tank 21 provided at the top of the engine 44. The fuel tank 21 is connected to the engine 44 via a fuel tank 46, and an exhaust manifold (not shown) provided on the engine 44 is connected to an exhaust manifold attached to an exhaust muffler 47. The intake manifold (not shown) is connected to the air cleaner 50 via the intake pipe 49.
The cooling water for cooling high temperature parts such as the exhaust manifold and cylinder head is cooled by the radiator 51.

As described above, the present invention surrounds the lamp bulb, reflector, and inner space provided inside the lamp cover with the lamp cover and lens, eliminating communication with the outside. etc. are all blocked by this lamp cover and lens and cannot enter the lamp cover, which may damage the lamp terminals or corrode the lamp cover, cord, mounting plate, etc. due to water accumulated at the bottom of the lamp cover. There is no need to fix the lamp with a special bracket, which helps reduce manufacturing costs, and color-coded blinkers are attached to both sides of the lamp cover, which greatly improves work safety. It makes a contribution.
