Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a mounting structure for a headlight disposed on the front of the front part of a tractor body, that is, on the front of the vehicle body.

(Prior art) A headlight opening and an air intake opening are provided in the front part of the front part of the car body such as the bonnet that defines the engine room, and exhaust ports are provided in both side parts of the front part of the car body. A tractor is known in which a radiator and a cooling fan are sequentially arranged behind an air intake opening inside the vehicle.

In the case of the above tractors, a grille cover that is similarly provided with an opening for headlights and an opening for air intake is generally provided on the front of the vehicle body. In the part, dried grass,
A net is installed to prevent problems such as foreign matter such as dry grass from entering with the air and clogging the radiator.

(Problem that the invention aims to solve) However, in the past, foreign matter such as dried grass and grass was carried by the air flowing in through the gap between the headlight opening in the grill cover and the headlight, and it entered the engine room and clogged the radiator. Then a problem arose.

The present invention was developed in view of the current situation, and is a tractor headlight that has a simple structure and prevents foreign objects such as dried grass and grass from entering through the gap between the headlight opening of the grill cover and the headlight. The purpose is to provide a mounting structure.

(Means for Solving the Problems) In order to achieve the above problems, the present invention provides an opening in the front part of the front part of the vehicle body that defines the engine room, fits a headlight in the opening, and In a tractor whose front part is covered with a grill cover having an opening for a headlight,
The front outer peripheral edge of the headlight faces the back side of the grill cover, and the headlight is provided with a flange projecting outward on its outer peripheral surface.

(Function) The air flowing in from the gap between the headlight opening of the grill cover and the headlight further flows outward along the outer peripheral surface of the headlight. However, according to the present invention having the above structure, the inflowing air first hits the front surface of the headlight and is bent, and then is further bent by the flange provided on the outer peripheral surface of the headlight and enters the engine room.

Therefore, the speed of air inflow is significantly reduced, and foreign objects such as dried grass and grass are not carried away by this air flow.

(Example) An example of the present invention will be described below based on the accompanying drawings.

In FIG. 1 showing an agricultural tractor to which the present invention is applied, 1 is a body frame, 2 is a front wheel, 3 is a rear wheel, 4 is a handle, and 5 is a seat.

As shown in FIGS. 1 and 3, an engine 8 equipped with a radiator 6 and a cooling fan 7 is mounted from the front on the front part of the vehicle body frame 1, and a bonnet 11 covering the front and both sides opens the engine compartment. R is defined.

The bonnet 11 is a press-molded product, and as shown in FIG.
3 and a front part 15, the side part 13 is formed with an air outlet part 14 for the cooling fan 7 in the engine room, and the front part 15 is formed with a central air intake part 16 and a front part 17 for the left and right headlights 17. opening 1
8 is formed, and an air intake slit portion 19 is further formed along the lower part of the front portion 15. In the illustration, openings 18 for headlights on the left and right sides of the front part 15 are shown.
extends toward the front of the side surface portion 13.

Further, a grill cover 21 is attached to the front surface 15 of the bonnet 11, and an exhaust louver 22 is attached to the exhaust port 14, respectively.

The grill cover 21 has a front part 15 and a side part 13.
Both sides are bent so as to cover a part of the center air intake part 23 and left and right headlight openings 24, and these openings 23,
An air intake slit portion 25 is formed below 24,
Nets 23a and 25a are stretched over the air intake portion 23 and the air intake slit portion 25.

In the figure, reference numeral 26 denotes a pair of left and right hinge plates, and as shown in FIGS.
8, and the tips of the arm pieces 27 and 28 have a cross section L.
The back plates 29, 29 of the mold are installed horizontally.

These back plates 29, 29 are connected to the headlight opening 1.
The hinge plate 26 is fixed by spot welding from the inside of the channel parts 30 and 31 disposed above and below the hinge plate 26, and the hinge plate 26 is fixed by spot welding from the inside of the channel parts 30 and 31 disposed above and below the hinge plate 26.
The stopper groove 33 is removably hinged to a pivot pin 36 and a stopper pin 37 that project from a hinge bracket 35 fixed to the vehicle body frame 1.

The hinge bracket 35 is used as a supporting member for the radiator 6, battery 38, etc., which are arranged around the hinge bracket 35.

Further, the space between the arm pieces 27 and 28 of the hinge plate 26 is a headlight relief portion 26b, and the bonnet 11 is provided in this headlight relief portion 26b.
A headlight 17 fitted into a headlight opening 16 provided in the front face 15 of the headlight faces.

As shown in FIGS. 1 to 4, the headlight 17 has a substantially rectangular parallelepiped-shaped front portion 41 and a rear portion 43 that narrows toward the rear.
A has a flange 45 that protrudes outward over its entire circumference.
is formed.

When the headlight 17 is fitted into the headlight opening 16, the headlight 17 has the flange 45 located in front of the opening 16 and the outer peripheral edge 47 of the front surface 17a facing the back side of the grill cover 21. ing.

According to this mounting state of the headlight 17, when the cooling fan 7 is rotated and cooling air is taken in from the air intake opening 16 and the air intake slit 19 in the front part 15 of the bonnet 11, the grille cover 21 and The air entering through the gap with the headlight 17, as shown by arrows A and B in FIG.
First, it collides with the front surface 17a of the headlight 17, bends, and flows along the outer peripheral edge 45, then flows along the outer peripheral surface 41a of the headlight front part 41, and immediately collides with the flange 45 and is bent. The speed of entry into the engine room R is significantly reduced.

Therefore, foreign matter such as dried grass and grass is not carried away by this air flow, so that the radiator 6 can be effectively prevented from being clogged by these foreign matter.

Further, in this embodiment, the lower edge 30a of the upper channel portion 30 faces the back side of the flange portion 45 of the headlight 17.

As a result, air flows through the gap between the upper part of the headlight 17 and the grill cover 21 (see arrow A in the figure).
After being bent by the collar part 45, the channel part 3
0 lower edge 30a and the flange 45 of the headlight 17
It curves in order to flow between the sides, resulting in a slower flow rate.

(Effects of the invention) As explained above, according to the invention, the front outer periphery of the headlight faces the back side of the grill cover, and the outer periphery is provided with a flange that projects outward, so that the grill cover The air flowing in through the gap between the headlight opening and the headlight first hits the front surface of the headlight and is bent, and then is further bent by the flange provided on the outer peripheral surface of the headlight and enters the engine room.

Therefore, the inflow speed of air is significantly reduced, and foreign matter such as dried grass and grass is not carried by this airflow and enters the engine compartment, effectively preventing clogging of the radiator due to these foreign matter. can.
