Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a cabin support bracket structure for a tractor with a cabin.

<Prior Art> Conventionally, cabin support brackets have been provided on both sides of the vehicle body of a tractor, and the cabin has been attached to the support brackets via a vibration isolating material such as rubber. For example, there is one shown in Utility Model Application Publication No. 11281/1983.

<Problems to be Solved by the Invention> The cabin support bracket of the above structure was used merely to support the cabin. Furthermore, when a large external force is applied to the cabin, a large load is applied to the support bracket, so it has been desired to improve the strength of the support bracket.
SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention aims to improve the strength of the support bracket and to also use it as a mounting part for a fuel tank.

<Means for solving the problem> The technical means is to provide a tractor with a cabin, in which cabin support brackets 21 and 22 are provided on both sides of the vehicle body 2, respectively, and the cabin 13 is attached and supported by the support brackets 21 and 22. 1, the front cabin support bracket 21 includes a fixing plate 23 attached to the outside of the vehicle body 2, and a cabin support 24 provided outwardly protruding from the outer surface of the fixing plate 23. A tank mounting plate 27 is welded substantially horizontally to the outer surface of the fixing plate 23, and a reinforcing rib plate 29 is welded to the upper surface of the tank mounting plate 27 and the rear surface of the cabin support 24. Fuel tank 3 on the bottom
0 is at the point where it is mounted and supported.

<Example> Hereinafter, an example of the present invention will be described based on the drawings. In Figs. 1 and 2, 1 is a tractor with a cabin, and 2 is a tractor formed by directly connecting an engine 3 and a transmission case 4, etc. A handle 6 is arranged at the rear upper part of the bonnet 5 that surrounds the engine 3, etc., and a rear axle case 7 is provided protruding from both sides of the rear part of the car body 2. Also, at the rear upper part of the car body 2, a handle 6 is arranged at the rear upper part of the bonnet 5 that surrounds the engine 3, etc. A hydraulic system 8 is installed.

Reference numeral 9 denotes a floor sheet that covers the upper side of the hydraulic system 8. A seat 10 is arranged above the floor sheet, and fenders 12 that cover the rear wheels 11 are provided on the left and right sides of the floor sheet.

Reference numeral 13 denotes a cabin, which is detachably attached to the vehicle body 2. A front panel 15 with a window, a rear panel 16, left and right side panels 17, and a top plate 18 are fixed to the frame 14, and left and right doors 19 are fixed to the frame 14. It is configured to be attached via a hinge. Left and right step 2
0 is formed integrally with the cabin 13, but may be formed separately and independently attached to the vehicle body 2.

The front lower part of the frame 14 of the cabin 13 is attached to and supported by a cabin support bracket 21 provided on the side surface of the vehicle body 2, and the rear lower part is attached to and supported by a cabin support bracket 22 bolted to the rear axle case 7. .

The front cabin support bracket 21 is attached to the vehicle body 2.
It includes a flat fixing plate 23 that is attached to the outside, and a cabin support 24 that is approximately U-shaped in side view and is welded to the outer surface of the fixing plate 23 so as to project outwardly. A vibration-proof mounting portion 26 is provided to support the cabin 13 via a vibration-proof material 25 such as elastic rubber. 27 is a tank mounting plate in the form of a rectangular flat plate, which is attached to the rear surface of the cabin support 24 and the fixing plate 2.
3. They are welded to each other in a substantially horizontal manner over the corner portions with the outer surfaces, and a plurality of insertion holes 28 are formed in the lateral direction. Furthermore, triangular reinforcing rib plates 29 are welded substantially vertically to the corner portions of the upper surface of the tank mounting plate 27 and the rear surface of the cabin support body 24, respectively.

Reference numeral 30 denotes a fuel tank, which is disposed below the step 20, the front end of which is held by a belt-shaped band member 31, and a male threaded shaft member 32 provided at the upper end of the band member 31 that allows the tank mounting plate 27 to be inserted therethrough. It is inserted through the hole 28 from below and connected with a nut 33, to which the front end is attached and supported. On the other hand, fuel tank 30
The rear end portion is similarly held by a belt-like band body 31, and is connected to a bracket body 34 provided on the side of the vehicle body 2 or the cabin 13 via a male threaded shaft body 32.
are connected to each other with a nut 33. In addition, band body 3
1 may be integrally fixed to the fuel tank 30 by welding or the like. Also, if they are placed below the steps 20 on both sides, the balance is good.

The embodiment of the present invention is constructed as described above, and the tank mounting plate 27 extends between the fixing plate 23 of the cabin support bracket 21 and the cabin support body 24.
are integrally welded together, and the reinforcing rib plate 29 is integrally welded over the cabin support body 24 and the tank mounting plate 27, so that the rigidity of the support bracket 21 can be improved and the strength can be improved. Further, since the fuel tank 30 is attached to the tank attachment plate 27, the support bracket 21 is also used as an attachment portion for the fuel tank 30, so that the number of parts can be reduced.

Although the fuel tank 30 is attached and supported by the band body 31 in a holding manner, it is also possible to weld a bolt to the fuel tank 30 and attach it with the bolt and nut. Not limited.

<Effect of the invention> According to the invention, the tank mounting plate is welded substantially horizontally between the outer surface of the fixed plate of the cabin support bracket and the rear surface of the cabin support, and the tank mounting plate is welded to the upper surface of the tank mounting plate and the rear surface of the cabin support. Since the reinforcing rib plate is welded over the support bracket, the rigidity of the support bracket can be improved and the strength can be improved. Furthermore, since the fuel tank is attached to the tank mounting plate, there is an advantage that members can be used for multiple purposes and the number of parts can be reduced.
