Description

  The present invention relates to agricultural wheels.

  As an agricultural wheel to be mounted on an agricultural machine such as a rice transplanter, a wheel part for mounting on a body axle, and an elastic ring provided in an annular shape (ring shape) surrounding the outer side of the wheel part in the radial direction What it has is known (for example, refer patent document 1 etc.). The elastic ring body is formed by providing a tire part made of an elastic material along the outer peripheral part based on a ring body core part formed in accordance with the annular shape of the elastic ring body. An inner flange portion projecting toward is provided. Further, there are a disc type and a spoke type having a circular shape or a triangular shape in the foil portion, and in each of the outer peripheral portions, a portion overlapping the inner flange of the elastic ring body is provided.

Therefore, the inner flange part of the elastic ring body and the outer peripheral part of the wheel part are overlapped, a bolt is pierced along this part along the axial direction of the fuselage axle, and a nut is screwed into the protruding part of the bolt. The wheel part and the elastic ring body are combined. Therefore, in the case of this agricultural wheel, the grounding load generated when it is mounted on the body axle is perpendicular to the axial direction (same as the axial direction of the body axle) with respect to the bolt used for coupling the wheel portion and the elastic wheel. Acts as a shear force.
In addition, since recent agricultural machines tend to improve the function by reducing the weight of the vehicle, it is necessary to reduce the weight of agricultural wheels as much as possible. In principle, luxury factors should be omitted thoroughly.

By the way, various types and sizes of agricultural machines have been manufactured in accordance with diversification of uses and needs from the user side. For example, even if one rice transplanter is mentioned, various types are prepared according to the degree of enhancement of functions from full-scale types to ultra-lightweight types, even though the number of planting strips is the same, and these are naturally added to the total vehicle weight. There is a difference. Therefore, the agricultural wheels may need to be strengthened in accordance with such circumstances on the aircraft side. Moreover, due to the presence or absence of optional devices and individual circumstances in use, it may be necessary to increase the strength of agricultural wheels.
JP 2000-255201 A

As described above, in the conventional agricultural wheel, the grounding load acts as a shearing force perpendicular to the axial direction on the bolt used for coupling the foil part and the elastic ring body. For example, when the number of bolts increases, it becomes necessary to increase the thickness of the inner flange portion in the elastic ring body in addition to increasing the number of bolts used or changing the bolts to thicker ones.
In this case, it is necessary to newly build or remodel the press die used for manufacturing the core body of the inner flange portion, and in some cases, it is necessary to newly construct or remodel even the mold for molding the tire portion. It was. These things can occur not only when the strength of agricultural wheels is requested to be increased, but also when promoting weight reduction (the omission of excessive strength structures).

For this reason, when changes in specifications such as changing the total vehicle weight frequently occur on the machine body side as described above, it is difficult to respond flexibly and promptly on the agricultural wheel side. Moreover, even if it could be dealt with, it was inevitable that the cost would be increased.
This invention is made | formed in view of the said situation, Comprising: It aims at providing the agricultural wheel which made it easy to raise the joint strength of a foil part and an elastic ring body.
In addition, the present invention increases the coupling strength between the wheel portion and the elastic ring body, so that it is possible to respond flexibly and promptly even when specification changes such as changing the total vehicle weight frequently occur on the aircraft side. An object of the present invention is to provide an agricultural wheel that can be prevented from becoming high.

In order to achieve the above object, the present invention has taken the following measures.
That is, the agricultural wheel according to the present invention has a wheel part for mounting on the body axle and an elastic ring body that is provided in an annular shape so as to surround the outer side in the radial direction of the wheel part. The elastic ring body is a ring-shaped ring body core having a buried portion provided in a tire portion using a pipe material as a raw material, and an inner flange portion provided by projecting the tire portion from the buried portion and projecting radially inward. Department.
Moreover, the superposition | polymerization part for fastening to which an inner flange part and the outer peripheral part of a foil part are overlapped and fastened by a fastening means is formed in the agricultural wheel.

The inner flange portion has a vertical portion parallel to a plane perpendicular to the body axle and a bent portion for a fastening overlapping portion. The vertical portion is provided at a radially outer position than the fastening overlapping portion, and is provided so as to protrude from the tire portion at the center position in the width direction of the tire portion.
The outer peripheral part of the foil part is bent so as to be parallel to the bent part of the inner flange part.
The overlapping portion for fastening is formed by inclining the bent portion of the inner flange portion and the outer peripheral portion of the foil portion with respect to a plane perpendicular to the body axle.

In this way, if the fastening overlapping portion formed by the inner flange portion of the elastic ring body (ring body core portion) and the outer peripheral portion of the foil portion is inclined, the fastening means provided on the fastening overlapping portion is also the machine body. It will tilt with respect to the axle. Therefore, in the agricultural wheel according to the present invention, the ground load acting on the fastening means is dispersed not only in the direction perpendicular to the axial direction but also the shearing force on the fastening means is alleviated.
For this reason, even if there is a specification change that changes the total vehicle weight on the machine body side, the fastening means (bolts, nuts, etc.) are bothered to be increased, or the ring body core part etc. are changed on the elastic wheel side. There is no need. Therefore, cost increase can be prevented.

Even if the fastening overlap portion is inclined by forming a vertical portion at a radially outward position from the fastening overlap portion at the ring core portion of the elastic ring body, It can support the ground load.
It is preferable that the fastening overlapping portion is inclined at an angle of 10 ° to 70 ° with respect to the body axle. If it exceeds 70 °, it is not sufficient to disperse the ground contact load, and if it is less than 10 °, mud adheres, which may cause inconvenience.
If a locking stopper that protrudes toward the outer peripheral part of the foil part at the radially outer end position of the fastening overlapping part is provided on the inner flange part of the core part of the elastic ring body, the surface at the fastening overlapping part This is preferable because it can completely prevent the direction deviation. The same applies to the case where a locking stopper that protrudes toward the inner flange portion of the ring body core portion of the elastic ring body at the radially inner end position of the fastening overlapping portion is provided on the outer peripheral portion of the foil portion.

Such a locking stopper can also be formed by bending the inner flange part of the ring body core part or the outer peripheral part of the foil part in the elastic ring body in the surface direction, and the ring body in the elastic ring body. It can also be formed by protrusions provided on the inner flange part of the core part or the outer peripheral part of the foil part.
The ring body core part of the elastic ring body has an embedded part provided in the tire part using a pipe material as a raw material, and an inner flange part provided through the tire part from the embedded part and projecting radially inward. In this case, the inner flange portion may have a surface joint portion that makes surface contact with the embedded portion following the outer surface of the pipe.

  According to the present invention, it is possible to easily increase the coupling strength between the foil portion and the elastic ring body. In addition, by increasing the coupling strength between the wheel part and the elastic ring body, it is possible to respond flexibly and quickly even when specification changes such as changing the total vehicle weight frequently occur on the aircraft side, which increases costs. Can be prevented.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 3 show an embodiment of an agricultural wheel 1 according to the present invention. The agricultural wheel 1 of this embodiment has a foil portion 2 and an elastic ring body 3 provided around the wheel portion 2.
The wheel portion 2 is a portion for mounting the agricultural wheel 1 to the body axle 4 of an agricultural machine such as a rice transplanter, and a connecting bolt 5 for connection to the body axle 4 is inserted through the central portion thereof. A mounting hole 6 is provided. In the present embodiment, the foil part 2 is a disk-shaped disk and is formed by press-molding a plate material. Accordingly, the outer peripheral portion 7 of the wheel portion 2 has a concentric circular shape centering on the axis of the body axle 4.

The elastic ring body 3 is formed in an annular shape so as to surround the outer side in the radial direction of the foil portion 2. The elastic ring body 3 is provided with a tire part 11 along the outer peripheral part of the ring body core part 10 based on a ring body core part 10 formed in accordance with the annular shape. The tire portion 11 is formed of an elastic material such as rubber, and is attached to the annular core portion 10 in a solid state by baking, for example.
The ring body core portion 10 extends inward in the radial direction as the elastic ring body 3 through the embedded portion 12 provided in the central portion of the tire portion 11 and the inner peripheral side of the tire portion 11 from the embedded portion 12. And an inner flange portion 13 provided in a protruding state.

In the present embodiment, the embedded portion 12 is formed by using a pipe material (round pipe) as a raw material, and the embedded portion 12 and the inner flange portion 13 are coupled by welding. Further, the inner flange portion 13 is abutted against the embedded portion 12 along the direction passing through the center thereof, and the abutting position is the center in the width direction as the tire portion 11 formed around the embedded portion 12. It matches the position.
The inner peripheral portion of the elastic ring body 3 (the inner flange portion 13 of the ring body core portion 10) and the outer peripheral portion 7 of the wheel portion 2 are overlapped with each other so as to secure a predetermined overlap allowance. The fastening overlapping portion 15 that comes into surface contact is formed. The fastening overlapping portion 15 is a portion for fastening the fastening means 16 when joining the elastic ring body 3 and the foil portion 2.

The fastening means 16 performs bolting with a bolt 17 and a nut 18, for example. The nut 18 may be fixed to either the elastic ring body 3 side or the wheel part 2 side by welding, or may be directly female threaded to either the elastic ring body 3 side or the wheel part 2 side. You may omit by providing a hole. The fastening means 16 may be riveted by rivets, or may be welded depending on circumstances.
When the fastening means 16 is to be bolted or rivet-fastened, the fastening means 16 is fastened among the inner peripheral portion of the elastic ring body 3 (the inner flange portion 13 of the ring core portion 10) and the outer peripheral portion 7 of the wheel portion 2. The through holes, such as bolts and rivets, are provided so as to match each other at a plurality of locations in the circumferential direction within the portion where the overlapping portion 15 is formed.

The fastening overlapping portion 15 is inclined with respect to a plane perpendicular to the body axle 4. This inclination is caused by bending the inner peripheral part of the elastic ring body 3 (the inner flange part 13 of the ring core part 10) and the outer peripheral part 7 of the wheel part 2 at the same angle while maintaining a mutual parallel relationship. Is provided. For this reason, the fastening means 16 to be provided in the fastening overlapping portion 15 is inclined with respect to the body axle 4 in the axial direction.
The inclination angle θ of the inclination provided in the fastening overlapping portion 15 is 10 ° or more and 70 ° or less with respect to the body axle 4, and more preferably 65 °. If the inclination angle θ is 10 ° or more and 70 ° or less, the ground load acting on the fastening means 16 is dispersed in the axial direction and the vertical (vertical) direction, and the shearing force is perpendicular to the axial direction of the fastening means 16. Therefore, the fastening means 16 is less likely to break or break.

Needless to say, when the inclination angle θ exceeds 70 °, the degree of dispersion of the ground load decreases as the angle approaches 90 °. Further, as shown in FIG. 16, when the inclination provided in the fastening overlapping portion 15 is set to a small inclination angle α less than 10 °, the mud 20 is removed when the elastic ring portion 3 is rotated from the ground contact state to the soft ground. If it leads to excessive lifting, and if the lifted mud falls from a high place, it will lead to a problem of damaging the seedling planted at a corner, which is not preferable.
In the elastic ring body 3, the inner flange part 13 of the ring body core part 10 forms a bent part for the fastening overlapping part 15 while leaving some of the part protruding from the tire part 11. Therefore, a vertical portion 21 is formed on the outer side in the radial direction of the fastening overlapping portion 15 by a portion that is left bent. The vertical portion 21 is parallel to a plane perpendicular to the body axle 4.

Such a vertical portion 21 is positioned at the center position in the width direction with respect to the embedded portion 12 and the tire portion 11. That is, since the ground wheel can support the ground load at the center position in the width direction of the elastic wheel 3 as a whole, the strength of the ring body core portion 10 can be increased and the support of the ground load can be stabilized. it can.
In the present embodiment, the outer peripheral portion 7 of the foil portion 2 is also formed with a bent portion along the vertical portion 21 (so as to be exactly overlapped). As a result, the fastening overlapping portion 15 extends to a part of the vertical portion 21. Therefore, the rigidity of the outer peripheral part 7 increases in the foil part 2, and the advantage that it is hard to produce position shift between the elastic ring body 3 side and the foil part 2 side as the superposition | polymerization part 15 for fastening is acquired.

A lug pattern is appropriately provided on the outer peripheral surface of the tire portion 11. For example, trapezoidal lugs may be arranged at the center in the width direction of the tire portion 11 along the circumferential direction, and triangular lugs may be attached to the left and right sides in a staggered arrangement. Moreover, what is necessary is just to make the inner peripheral surface side of the tire part 11 the shape etc. which protruded in the cross-sectional mountain shape by using the center part in the width direction as a top part. Such a detailed structure and shape regarding the tire portion 11 can be arbitrarily selected.
As is apparent from the above detailed description, the agricultural wheel 1 according to the present invention has the inner peripheral part of the elastic ring body 3 (the inner flange part 13 of the ring body core part 10) and the outer peripheral part 7 of the foil part 2 overlapped. In addition, they are brought into surface contact with each other to form a fastening overlap portion 15, and the fastening overlap portion 15 is firmly fastened by the fastening means 16.

When the agricultural wheel 1 assembled in this way is mounted on an agricultural machine and fixed to the machine axle 4 of the agricultural machine through the mounting hole 6 of the foil part 2, the fastening superposition part 15 is against the plane orthogonal to the machine axle 4. Therefore, the fastening means 16 provided in the fastening overlapping portion 15 is naturally inclined with respect to the body axle 4.
Therefore, in this agricultural wheel 1, the ground load acting on the fastening means 16 is dispersed in the axial direction and the vertical (vertical) direction, and the shearing force is not concentrated in the direction orthogonal to the axial direction of the fastening means 16. Therefore, breakage, breakage, and the like hardly occur in the fastening means 16. Therefore, even if there is a specification change that changes the total vehicle weight on the machine body side, there is no need to bother to reinforce the fastening means 16 or to change the design of the ring body core portion 10 or the like on the elastic wheel body 3 side.

In addition, since the foil part 2 and the elastic ring body 3 can be manufactured separately, in the process of manufacturing the foil part 2 and the process of manufacturing the elastic ring body 3, each original work (painting method and paint, etc.) It is possible to proceed separately and independently), and it also has secondary effects such as reduction in manufacturing cost and response to detailed needs.
FIG. 4 shows a reference example of the agricultural wheel 1 . In the agricultural wheel 1, the most different point from the above-described embodiment of FIGS. 1 to 3 is a state in which the inner flange portion 13 of the ring body core portion 10 is inclined obliquely with respect to the embedded portion 12 in the elastic ring body 3. The tire portion 11 is abutted and is formed around the buried portion 12 so as to protrude at a position shifted from the center position in the width direction. Therefore, there is no vertical portion 21.

In the agricultural wheel 1 of this embodiment, the most different point from the embodiment of FIGS. 1 to 3 described above is that a locking stopper 30 is provided in the vicinity of the outer peripheral portion 7 in the foil portion 2. The locking stopper 30 is positioned so as to protrude toward the inner peripheral portion (inner flange portion 13) of the ring body core portion 10 in the elastic ring body 3 at the radially inner end position of the fastening overlapping portion 15. It is completely prevented that surface direction deviation occurs in the overlapping portion 15 for fastening between the elastic ring body 3 side and the wheel portion 2 side.
The locking stopper 30 can be formed as a projection by welding the wire or by the welding bead itself. The locking stopper 30 can be formed as an annular continuous protrusion along the outer peripheral part 7 of the foil part 2 or can be formed as a plurality of chip-like protrusions divided in the circumferential direction.

This locking stopper 30 also has an effect of sharing the ground load received by the elastic ring body 3, and has an advantage that the ground load acting on the fastening means 16 can be reduced accordingly. Other configurations and operational effects are substantially the same as those of the embodiment of FIGS. 1 to 3, including that the fastening overlapping portion 15 is inclined with respect to the direction orthogonal to the body axle 4.
FIG. 6 shows another embodiment of the agricultural wheel 1 according to the present invention. Agricultural wheel 1 of this embodiment, the embodiment of FIG. 5 is obtained by the subject locking stopper 30 is provided in relative opposite. That is, the locking stopper 30 is provided with respect to the inner peripheral portion (inner flange portion 13) of the ring body core portion 10 in the elastic ring body 3, and the wheel portion 2 at the radially outer end position of the overlapping portion 15 for fastening.

They are provided in parallel. In accordance with this, the inner flange portion 13 of the ring body core portion 10 of the elastic ring body 3 is also formed as a vertical portion 21 that is parallel to a plane perpendicular to the body axle 4, all of the portion protruding from the tire portion 11. It is. Therefore, the fastening overlapping portion 15 formed when the elastic ring body 3 and the foil portion 2 are combined is parallel (that is, not inclined) with respect to a plane perpendicular to the body axle 4.

Thus, even when the fastening overlapping portion 15 is not tilted, the locking stopper 30 does not cause a surface direction deviation in the fastening overlapping portion 15 and an effect of sharing the ground load received by the elastic ring body 3 can be obtained. Thus, concentration of shearing force on the fastening means 16 is prevented and breakage or breakage is less likely to occur. As a result, even if there is a specification change that changes the total vehicle weight on the airframe side, There is no need to change the design of the ring core 10 or the like on the elastic ring body 3 side.
