Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a front grill arranged on the front surface of the bonnet of a traveling vehicle such as a tractor.

<Prior art> For example, in the front grill of an agricultural tractor, a headlamp is attached to the grille body, and a ventilation section is formed through which the radiator cooling air flows, and this ventilation section is covered with a wire mesh to prevent dust from entering. It is provided.

The front grill has various designs, and when a headlamp is placed at the top and a ventilation section is placed at the bottom, a front guard is placed in front of it to protect the wire mesh of the ventilation section from trees. .

Conventionally, this front guard was integrally molded into the grille body as a crosspiece of the ventilation section.
It is closely connected to the wire mesh.

<Problems to be solved by the invention> In the conventional technology, when the crosspiece is a horizontal crosspiece, dust tends to accumulate on the upper surface of the crosspiece, and when it accumulates, the wire mesh becomes an obstacle and is difficult to remove. There were problems such as the wire mesh also deforming when it was hit and deformed.

<Means for solving the problem> The present invention has the front guard 10 attached to the grill body 1.
3 and a separately formed member 15 installed in a horizontal frame shape,
By separating the horizontal beam 15 from the wire mesh 14 and allowing dust to fall, all of the problems of the prior art can be solved.

That is, the specific structure of the problem-solving means of the present invention is characterized by attaching a wire mesh 14 to the inner surface of the ventilation section 12 of the grill body 13;
In the front grill in which a front guard 10 is arranged on the front side of the front grille 4, the front guard 10 includes a plurality of horizontal members 15.
Each horizontal bar member 15 has a gap 27 between it and the wire mesh 14, and its upper surface is a downward surface onto which dirt and the like can fall.

<Function> The horizontal beam 15 of the front guard 10 protects the wire mesh 14 from trees, and even if it deforms when it hits a tree, the wire mesh 14 is unlikely to be deformed due to the gap 27, and dirt and the like will not accumulate on its upper surface. Even if an attempt is made to do so, since the surface faces downward, dirt and the like will fall, and because of the gap 27, it will not accumulate between it and the wire mesh 14.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIGS. 1 to 4, reference numeral 1 denotes a front grill at the front end of the bonnet of an agricultural tractor, which is detachably attached to a support frame 2. The support frame 2 has a battery support 4 fixed to the front axle frame itself or a base 3 attached to it, and a pair of left and right columns 5 are erected from this support 4 and reinforced with reinforcing material 5. The upper end and the middle part are connected to the horizontal members 7 and 8.
It is formed by connecting.

The front grill 1 is divided into upper and lower halves, and the upper front grill 1A includes a grill main body 13A having a ventilation section 12A through which radiator cooling air passes;
Wire mesh 14A attached to the inner side of the ventilation section 12A
It has a horizontal bar 15A disposed on the front side of the wire mesh 14A, and a pair of left and right head lamps 16, etc., and a horizontally long bracket 17 is bolted to the upper part of the rear side of the grill body 13A. Small brackets 18 are fixed on the left and right sides in the middle. The bracket 17 is attached to a mounting body 19 fixed to the horizontal member 7 of the support frame 2 so as to be adjustable in its longitudinal position, and the small bracket 18 is attached to a mounting body 20 fixed to the left and right ends of the horizontal member 8.
installed on.

The lower front grill 1B has ventilation portions 12B formed on the front and most of the left and right sides of the grill body 13B, and has a wire mesh 14B, a plurality of horizontal members 15B, etc., almost the same as the upper front grill 1A. The upper part of the back side of the grill body 13B is the support frame 2
It is attached to a mounting body 21 provided in the middle of the support column 5 via bolts 22, and the lower part is attached to the base 3 with bolts 22.
It is attached via 3.

The upper and lower grill bodies 13 are made of cast iron, are thick and heavy, have higher strength than conventional grills made of sheet metal or synthetic resin, and also serve as front weights. This reduces breakage and
There is no need to separately provide a front weight.

A plurality of vertical bars 24 are integrally molded in the ventilation section 12 of the upper and lower grill main bodies 13, and a wire mesh 14
The peripheral edge thereof is attached along the inner surface of the grill body 13 via screws 25. However, wire mesh 1
4 includes punching metal and synthetic resin netting.

The horizontal beam 15 forms the front guard 10 and is made of bar material, pipe material, etc., and its cross-sectional shape can be of any shape such as circular, oval, or square. The surface faces downward to prevent rainwater from accumulating.

The horizontal beam member 15 follows the substantially U-shape of the ventilation portion 12 of the grill body 13 in plan view, and its both ends are attached to the grill body 13 by screwing bolts 26 passing through the grill body 13. It is fixed, detachable and replaceable. The bolts 26 also serve to attach the wire mesh 14.

The wire mesh 14 is in contact with the inner surface of the vertical bar 24, but the horizontal bar 15 is located in front of the vertical bar 24, and there is a gap 27 between the wire mesh 14 and the wire mesh 14 to allow dust to fall. It is formed.

Note that the front grill 1 includes upper and lower grill bodies 1.
3A and 13B can also be formed integrally.

Further, in FIG. 1, reference numeral 28 indicates a top plate of the bonnet, and a bracket 29 attached to the front part of this top plate 28 is bolted to the mounting body 19.

<Effects of the invention> According to the invention detailed above, the front guard 10 is formed by attaching a plurality of horizontal bars 15 to the grill body 13, and each horizontal bar 15 has a gap 27 between it and the wire mesh 14. Since the grill body 13 does not have horizontal bars and is easy to manufacture, even if the horizontal bars 15 are deformed and damaged by hitting a tree, they can be easily replaced. This is economical since there is less deformation and damage to the wire mesh 14, and it is also possible to prevent dirt and the like from accumulating between the upper surface of the horizontal beam 15 and the wire mesh 14, making cleaning easier.
