Description

[Detailed Description of the Invention] The present invention relates to a dust prevention device for preventing dust from entering the radiator from the battery side in an agricultural tractor in which the battery is mounted on the front side of the radiator.

Conventionally, the installation structure of the radiator and battery in an agricultural tractor is as shown in Fig. 1. Front axle brackets 2 protruding forward are attached to both sides of the lower part of the engine 1, which forms part of the machine body. A radiator bracket 3 is erected on the front protrusion, and a radiator 4 is installed inside a bonnet 6, and a battery 5 is placed on the front side of the radiator 4.

In this case, a seal plate 7 is provided to cover the upper rear part of the battery 5 to prevent dust from entering from the battery 5 side. Since bolts 8 are fixed to , and as a result, there was a problem in that dust entered the radiator 4.

9 is a metal fitting for mounting the battery.

The present invention was made with the aim of eliminating such conventional drawbacks, and by making the seal plate rotatable, there is no need to remove the seal plate each time the battery is removed. It is an object of the present invention to provide a new seal plate mounting structure in which the seal plate does not swing up and down during travel even when the seal plate is rotatable.

The structure of the present invention will be explained based on a drawing showing an embodiment. As shown in FIG. Bracket 1
A radiator bracket 12 is installed upright on the front protrusion of the radiator bracket 12, and a radiator (
(not shown) are installed and fixed by bolts 13 as is conventional.

Reference numeral 14 denotes a battery mounting plate which is buttoned on the front side of the radiator bracket 12 and attached to the upper surface of the front axle bracket 11. The battery 15 is mounted on the upper surface of the battery mounting plate 14.

Further, a bonnet support piece 16 is erected on the upper surface of the front axle bracket 11 on the front side of the battery 15.

Reference numeral 17 indicates the lower part of the main body of the bonnet 18 that covers the battery 15 and the upper and side surfaces of the radiator, 19 indicates a girder installed within the bonnet 18, 20 indicates the bonnet front grill, and 21 indicates the girder 19 and the front grill. 20
The sealing material 22 inserted in the gap between the gaps is a bonnet hinge plate that hangs down and is fixed to the lower surface of the girder 19. The bonnet 18 is rotatably attached, and the bonnet 18 can be opened and closed by rotating around this hinge portion.

Now, go back to the 12th part of the radiator bracket, and
is a partition plate that is stretched over the lower front surface of the radiator bracket 12 and covers the space between the back and the upper part of the battery 15, and a seal bracket 25 is attached to the upper end of the partition plate 24;
A seal plate 27 according to an embodiment of the present invention is attached to the seal bracket 25 via a pin 40 so as to be rotatable upward.

28 is a sealing material interposed between the partition plate 24 and the battery 15.

In the above, the shape of the seal bracket 25 is shown in FIG.
As shown in FIG. 8, a trapezoidal notch 30 is formed in the upper center of the vertical bracket body 29 formed in the shape of a long and thin plate extending from side to side. One piece of a horizontal plate 31 formed in a cross-sectional shape is fixed to the front surface of the bracket body 29, and the other piece projects horizontally forward, and a support piece 33 having a pin hole 32 is provided at the inner end of the horizontal plate 31. is fixed.

At the upper end of the bracket body 29, fixing pieces 34 are provided upright near both left and right ends, and are also held at the center of the back surface of the bracket body 29 with a gap between the bracket body 29 and the body 29. A piece 35 is fixed, and this holding piece 35
The seal bracket body 29 is attached to the bulkhead plate 24 by inserting the upper end of the bulkhead plate 24 into the gap between the radiator bracket 12 and the main body 29, and the fixing piece 34 is attached to the radiator bracket 12 with the bolts 36 to secure the seal. Bracket 25 is fixed.

Further, the horizontal plate 31 of the seal bracket 25 is formed with four downwardly recessed portions 37, and insulating rubber 38. FIG. 3 is covered.

The seal bracket 25 can also be attached to the radiator using the above button.

Alternatively, a special bracket may be installed upright from other fixed parts such as the front axle bracket 2 which is the tractor body.

Next, the seal plate 27 is
As shown in FIG. Side wall plates 43 having pin holes 42 are fixed to both left and right ends of the plate.

The left and right width of this intake guide part 41 is a length that approximately corresponds to the notch 30 of the seal bracket main body 29, and when the intake guide part 41 is inserted inside the support piece 33 of this seal bracket main body 29, Both ends of the pivot pin 40 are inserted into the support piece 33 and the side wall plate 43, and the seal plate 27 is attached so as to be rotatable upward.
l Notch part j of intake guide part 41 and seal bracket 25
30, the seal plate 27
An intake guide path 44 that guides air from the top surface to the back side of the partition plate 24. 4, in which the rear end of the plate main body 39 overlaps the upper surface of the seal bracket horizontal plate 31.

Further, on the left and right sides of this plate main body portion 39, recesses 45 that are recessed downward over a certain area are formed.
An insulating rubber 46 is fitted and coated on the outside.

3 and 4 is a holding plate whose front end is attached to the bonnet beam member 19 through a fixing piece 48, and this holding plate 47 extends rearward to hold the battery 15. While covering the upper part of the front side, the rear end overlaps the upper surface of the seal plate 27 and presses the seal plate 27. At this time, the lower surface of the crest press plate 47 has a portion that corresponds to the seal plate 27. A sealing material 28 made of polyurethane resin or the like is pasted on.

In addition, the center part of the rear end of this presser plate 47 is as shown in FIG.
A large notch is provided to avoid the intake guide portion 41 of the seal plate 27 and open the intake guide path 44 .

Now, in order to remove the battery 15 in the above configuration,
When the bonnet 18 is opened, the presser plate 47 will rotate upward accordingly, so the seal plate 27 can then be rotated upward.

Therefore, according to the present invention, there is no need to remove the seal plate 27 one by one as in the conventional case, and therefore the battery 15
The removal of the seal plate 27 is extremely easy, and since the seal plate 27 is always attached, the conventional inconvenience of forgetting to attach it is eliminated. Since this seal plate is held down by the presser plate that covers the upper part, the seal plate does not swing up and down to open and close while the vehicle is running, and the intrusion of dust can be reliably prevented.
