Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a wheel mounting portion for an agricultural vehicle equipped with a wheel in which a disk is bulged so that the hub portion is positioned laterally outward from the width center of the tire.

By forming the disk in the above-described shape, the above-mentioned wheel is designed so that the wheel reduction case can be stored inside the wheel without protruding from the wheel to the inside of the vehicle body as much as possible, or the tire can be positioned between the ridges of the axle from the end of the axle. It is also constructed so that it can be placed inside the vehicle body. Therefore, in the past, a part of the wheel mounting screw for the axle protruded laterally outward than the tire.
As this protruding portion rotates around the wheel axis, the crops may be hit by the wheel mounting screws or become entangled and damaged, causing them to break.

The purpose of the present invention is to provide a structure that can easily prevent crop damage.

A feature of the present invention is that, in the above-mentioned structure of the wheel mounting portion of the agricultural vehicle, a ring surrounds the protrusion of each of the plurality of wheel mounting screws to the axle from the disk to the lateral outer side, extending over the entire length of these protrusions. The structure consists in that the shaped body is removably attached to the disk in a concentric manner, and its functions and effects are as follows.

That is, the ring-shaped body covers the wheel mounting screw so that it is difficult to touch the crops. Moreover, since the ring-shaped body surrounds all of the wheel mounting screws and has a large diameter, it is difficult to get the crops caught in it, and since it rotates around the axle center, it does not hit the crops. Therefore, it is possible to prevent the crops from getting entangled with the wheel mounting screws and the ring-shaped body and from being hit, and it is possible to work smoothly without damaging the crops and causing quality deterioration. The structure was simple, just adding a ring-shaped body, and it was economically advantageous.
Moreover, by making the ring-shaped body removable,
Weights for increasing the ground pressure of the wheels and adjusting the front and rear weight of the vehicle body can be easily attached by removing the ring-shaped body, making it possible to advantageously adjust the weight.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in Fig. 1, a pair of left and right front wheels 1, 1
A lift arm 3 that connects various working devices such as a rotary tiller so that it can be raised and lowered freely, and a power take-off shaft 4 that transmits power to the connected working device are provided at the rear of the traveling body having rear wheels 2, 2. It is configured as an agricultural tractor.

As shown in FIG. 2, the front wheel 1 is constructed by:
The disk 5 is formed in a bulging manner so that the hub portion 6 is positioned laterally outward from the width center of the tire 7, and the deceleration mechanism 9 of the transmission case 8 is installed inside, and
The axle 10 is arranged so that the portion 8a, which is attached to the axle 10 so as to be able to freely adjust the amount of protrusion for changing the tread, is located in the inner wheel space on the inner surface of the disk 5. bolt 1
1 is attached to the axle 10 by...

The ring-shaped body 12 that surrounds the head 11a of each of the wheel mounting bolts 11 that protrudes laterally outward from the disk 5 has a length that protrudes from the disk 5 so as to surround the entire length of each of the bolt heads 11a. The disc 5 is mounted using the wheel mounting bolt 11 in a state where it is formed into a shape larger than the protruding length of the wheel mounting bolt 11 and arranged concentrically with the disc 5 so as to rotate around the axle center. It is configured to be removably attached to the bolt head 11a and to cover the bolt head 11a to prevent it from coming into contact with crops.

Similarly to the front wheel 1, the rear wheel 2 also has a disk 5 formed in a bulging manner, and a ring-shaped body 12 is attached thereto.

The ring-shaped body 12 may be mounted using a dedicated mounting screw other than the wheel mounting bolt 11.

The wheel mounting bolt 11 can be changed to a wheel mounting configuration consisting of a bolt embedded in the axle 10 and a nut therefor, and these are collectively referred to as wheel mounting screws 11.

The present invention can also be applied to various agricultural vehicles such as agricultural transport vehicles.
