Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an attachment structure for attaching attachments such as a roll visor, a roll bar, a safety frame, and a cabin to the body of an agricultural tractor.

Conventional Technology Recently, agricultural tractors have been equipped with attachments such as roll visors, roll bars, safety frames, and cabins to accommodate the diversification of tractor operations or to improve safety. However, the reality is that conventionally these attachments have been individually attached to the aircraft body via separate attachment means.

Conventional tractors also carry fertilizers, crops, etc.
Alternatively, because they do not have the ability to load heavy objects such as tools necessary for agricultural work, these heavy objects are actually transported via implements such as carriers and trailers.

Problems to be Solved by the Invention However, in the method of separately attaching attachments such as roll visors by husband's means as described above, the number of parts for attachment inevitably increases; There is a problem that needs to be solved in that it becomes troublesome to attach and detach, resulting in significant waste in terms of cost and time.

In addition, when transporting heavy materials such as fertilizer, it is necessary to prepare an implement such as a carrier in addition to the tractor, which results in significant operational inefficiency, which is another problem that needs to be resolved. .

The present invention is an attempt to improve the above-mentioned problems, and the purpose of the present invention is to reduce the cost of attachments such as roll visors by sharing the mounting part of the attachments. In addition to making it easy to attach and detach, it is also possible to load heavy items such as fertilizer through the attachment part of the attachment.

The specific means and actions for solving the above problems are as follows.

Means for Solving the Problems Flange pieces are provided at both upper and lower ends of a pair of left and right frame rods that rise from the rear axle case toward the fender, and mounting holes are formed in each of the flange pieces.

A mounting bolt is formed by connecting multiple U-shaped bolts in parallel, and the mounting bolt is held against the final case from below, and each threaded portion of the mounting bolt is connected to the lower end of the frame rod. It is inserted through a flange piece provided in the section and fastened with a nut.

The flange piece provided at the upper end of the frame rod faces the horizontal part of the fender so as to touch the lower surface thereof, and the horizontal part of the fender and the attachment placed on the same horizontal part have openings in the flange piece. Attachment holes are opened corresponding to the attachment holes, and bolts are inserted through each of the attachment holes and tightened together with nuts.

Function: The mounting part of the attachment can be used in common, and if no attachment is attached to the mounting part, heavy objects can be loaded by attaching the loading platform as an attachment.

Specific embodiments of the present invention will be described below.

Embodiment 1 is a frame, and a front wheel 2 is mounted on the frame 1 via a front axle case 2', and an engine 3 is mounted on the frame 1. For the engine 3, a clutch housing case 4, a transmission case 5, and a final case 6 are arranged rearward in a line (hereinafter collectively referred to as "powertrain 7"), and a final case 6 is provided. A rear wheel 8 is mounted on the case 6 via a rear axle case 8'.
Also, the final case 6 has a lift cylinder 1.
6 is fixed to the lift cylinder 16, and a fuel tank 23 is placed on the lift cylinder 16.

A pair of left and right low floor portions 9, 9 are provided between the front and rear wheels 2, 8 (dead space) located on both sides of the power train 7, and one of the low floor portions 9, 9 is located on both sides of the power train 7. is used as an exercise space. In the exercise space, a steering wheel 10 and a seat 11 are provided facing each other in the front and rear.

In addition, an engine 3 and front wheels 2 are installed at the front end of the aircraft.
A bonnet 15 is attached to cover the rear wheels 8, while a fender 14 is attached to the rear end of the aircraft so as to cover the rear wheels 8. Same fender 14
is formed into an inverted L-shape, including a horizontal portion 14A and a forward inclined portion 14B extending obliquely forward and downward from the front end of the horizontal portion 14A, and the horizontal portion 14A and the forward inclined portion 14B are located on the left and right sides thereof. It is provided so that the rear wheels 8, 8 can be covered at both ends.

Further, a pair of left and right frame rods 18, 18 are provided in the final case 6 in an upright manner. More specifically, flange pieces 19, 19 are provided at the lower ends of the frame rods 18, 18, mounting holes are opened in the same parts, and a plurality of U-shaped bolts 21, 2 are provided.
1 are arranged in parallel and their bottom portions are connected by a joining member 26 to form a mounting bolt 27, and the mounting bolt 27 is provided to the final case 6 so as to be held from below,
The U-shaped bolts 21, 21 are inserted into the mounting holes, and a nut is screwed onto the tip end of the bolts 21, 21 to attach the bolts. And also, the same frame rod 18,
18 extends upward, and its tip is provided so as to face the horizontal portion 14A of the fender 14. Flange pieces 20, 20 are provided at the tip portions (upper ends) of the frame rods 18, 18, and mounting holes are opened in these portions. Further, a through hole is opened in the horizontal portion 14A of the fender 14 in correspondence with the above-mentioned mounting hole.

A roll visor 22 is attached to the horizontal portion 14A of the fender 14 as an attachment. More specifically, a flange piece 24 is provided at the lower end of the roll visor 22, and a mounting hole is opened in the flange piece 24 in correspondence with the through hole. Then, by inserting a bolt through the mounting hole and between the through hole and the mounting hole, and screwing a nut onto the tip of the bolt, the mounted state of the roll visor 22 as shown in FIG. 1 is achieved. can get.

On the other hand, FIG. 3 is a drawing showing another embodiment, in which a loading platform 25 is provided on the horizontal portion 14A of the fender 14.
is attached as an attachment. More specifically, a mounting hole is opened at the bottom of the loading platform 25 in correspondence with a through hole opened in the horizontal portion 14A of the fender 14, and a bolt is inserted through the mounting hole and between the through hole and the mounting hole. By screwing a nut onto the tip, an attached state as shown in FIG. 3 can be obtained. 12 is a radiator, and 13 is a steering gear box.

Effects of the invention The invention is constructed as described above.
As mentioned above, a pair of left and right frame rods are provided to stand up from the rear axle case, and their tips face the horizontal part of the fender, and a mounting part with bolts and nuts is provided in the same part, and a roll visor is attached to the mounting part. By making it possible to selectively attach roll bars, safety frames, cabins, etc. as attachments, it has become possible to share the attachment parts for these attachments, and as a result, it is now possible to attach attachments to the aircraft. In addition to being able to reduce the number of parts and reducing costs accordingly, it has also become possible to easily attach and detach each attachment. In addition, a mounting bolt is formed by connecting multiple U-shaped bolts in parallel and connecting their bottom parts with a joining member, and the lower end of the frame rod is fixed to the final case by the mounting bolt. By doing so, it has become possible to assemble it with simple work.

Furthermore, in the present invention, by having the structure as described above, in addition to being able to increase the strength of the fender part by using the frame rods, it is also possible to attach a load receiving stand as an attachment to the above-mentioned mounting part. For example, fertilizer,
It has now become possible to load harvested products and agricultural tools. In other words, it has become possible to load and transport heavy objects on a tractor.
