械をとめて土落しを行うのが通常である。 Agricultural machinery used in fields, such as transplanters, seeders, weeders, and harvesters, are often designed to run using belt-shaped wheels, and these types of wheels do not touch the ground. , which has a considerable width in order to support the fuselage. Therefore, when the vehicle touches the ground and runs in a field, if the field has a lot of moisture or the soil is soft and viscous, a large amount of soil will adhere to the wheels. When dirt adheres, various troubles occur during work. For example, the outer diameter of the wheels becomes substantially larger, increasing the distance traveled per rotation, so it is necessary to link the wheels to a grounding wheel like a transplanter. If the planting mechanism is rotated, the planting interval will increase or the slip rate will change, making it impossible to transplant at regular intervals. Furthermore, if the soil adheres to the left and right wheels differently, many problems occur, such as the balance of the machine being lost or the soil adhering to the wheels getting mixed into the harvest. There are not many active preventive measures against this, and it is simply a matter of wisdom in daily life.
Empty plastic bags, etc., are wrapped around the wheels to reduce soil adhesion, but this method requires a lot of effort to wrap the empty bags, and is not very durable. It has the disadvantage that it is easy to fall into the soil, and even if such means are used, soil cannot be sufficiently prevented from adhering to the soil. Therefore, it is common practice to stop the machine and remove soil each time a large amount of soil adheres to the machine.

より解決した。 The inventors of the present invention conducted research to solve the above problems and create a tool that can be operated while preventing soil adhesion and slipping due to differences in soil moisture and soil quality.As a result, they found that soil has plasticity. , focusing on the fact that when attached to an elastic body such as rubber, it easily falls off due to expansion and contraction, the outer peripheral surface of the belt-shaped wheel is surrounded by a belt-shaped annular elastic body, and the outer periphery of the annular elastic body has a smooth part and many protrusions. The problem was solved by providing a number of spaces between the inner surface and the outer peripheral surface of the wheel to prevent slipping and to prevent soil from adhering due to expansion and contraction of the elastic body.

indicates a wheel, usually an iron wheel with a diameter of 30 to 60 cm.
The outer peripheral surface 2 is made smooth to increase the ground contact area, and a large number of chevron-shaped protrusions 3 are provided on the outer surface to prevent slipping. Eight to twenty chevrons each having a width of 10 cm are provided for each wheel 1. The wheel may be a driving wheel or a driven wheel of an agricultural machine such as a transplanter, a seeding machine, a weeding machine, a harvester, or a towing vehicle, or it may be a wheel such as a turf wheel or a suppression wheel. good. The wheel 1 usually has spokes 4 or a support in place of the spokes on the inside, and a flange 5 that fixes the spokes 4 at the center of the circle.An axle 6 is fixed at the center of the flange 5, and a An agricultural machine such as a transplanter (not shown) is placed thereon, and the axle 6 is driven to move it forward, and the rotation of the axle 6 is transmitted to the rotation of the working machine. The wheel 1 is provided with a collar 7 on both sides thereof, and a band-shaped annular elastic body 8 surrounding the wheel 1 and the collar 7 is detachably attached to the outside of the wheel 1 and the collar 7. This annular elastic body 8 is made of synthetic or natural resin having elasticity, and Table 1 shows a compounding example when it is made from raw rubber or synthetic rubber.

要する。 Since the belt-shaped annular elastic body 8 is detachably attached to the wheel 1 as described above, it is annular and has a width and diameter slightly larger than the width of the wheel 1, and covers the belt-shaped outer circumferential surface 2. It is made to have a smooth portion 9 and a protrusion 10 that covers the protrusion 3. Further, in order to facilitate attachment to the wheel 1, the annular elastic body 8 is provided with wheel mounting ears 11, 11 and ears 11, 11 on both sides.
Folded parts 12, 12 are provided at the ends of the wheel 1, and when the wheel is mounted, the ear part 11 is placed on the flange part 7 of the wheel 1, surrounded by the folded part 12, and held from both sides. Note that the wall thickness of the ear portion 11 and the folded portion 12 may be thinner than the wall thickness of the smooth portion 9 and the protruding portion 10. A large number of ribs 13, 13... are horizontally stretched on the back side of the smooth portion 9 and the protrusion 10,
A closed system space 14, 14, . . . is formed between the rib 13 and the rib 13. Normally, the height of the ribs 13 is about 2 to 7 mm, the width is about 2 to 7 mm, and the pitch between each rib is 30 mm.
A value of ~80 mm is appropriate, and care must be taken as making the height too high or too low, or making the pitch too long or too short, will impede the soil removal effect of the annular elastic body 8.

ることがないのである。 When the annular elastic body 8 is attached to the wheel 1 as described above and placed in a field, the ground contact portion of the annular elastic body 8 is pushed by the weight of the machine and deforms. This deformation occurs strongly toward the space 14 between the ribs 13, 13, so
The soil is compacted against its surface and remains attached as it is compacted due to the plasticity of the soil. Next, when the wheel 1 rotates, the annular elastic body 8 leaves the ground, so the pressure is released and it quickly returns to its original state. However, the attached soil tries to maintain its shape, so it peels off. This phenomenon occurs not only in the smooth portion 9 but also in the protruding portion 10, and the protruding portion 10 reliably penetrates into the ground to prevent slipping. Therefore, the distance that the wheel 1 moves forward with one revolution does not always change, and the rotation of the agricultural machine driven by the axle 6 is always constant relative to the progress of the machine, so that the above-mentioned planting intervals etc. do not change. There is no.

である。 As described above, the present invention provides the smooth part 9 and the protruding part 10 on the outside of the annular elastic body 8, and the rib 13 and the space 14 constituted by the rib 13 on the inside of each, making it detachable from the wheel. However, the protrusion 10 can be modified in various ways. That is, when using a wheel 1 having a completely smooth outer circumferential surface 2, as shown in FIG.
3 to form a space 14 between the iron projection 15 and the rib 13 to press the iron projection 15 to the wheel 1. As shown in FIG. Alternatively, as shown in FIG. 8, a chevron-shaped protrusion made of rubber or the like may be fixed to the wheel 1 with a bolt 19, and the rib 13 of the protrusion 10 may be placed on top of it so that the ribs 13 of the protrusion 10 face each other. A space 14 may be formed in between, as shown in FIG.
The protrusion 10 may be placed on top of the protrusion 10.

たつて使用することができる。 The present invention has been developed as described above, and even when working in a wet and sticky field, there will be no trouble at all due to soil adhesion while driving, and the planting mechanism, harvesting mechanism, and other rotating mechanisms that are linked to the ground contact wheel will The rotation is always maintained normally and slips can be prevented, allowing for stable work. Since the annular elastic body 8 of the present invention is detachable from the wheel, it can be removed and stored when unnecessary, so it can be used for a long period of time with little wear and tear.
