Description

[Detailed description of the invention] The present invention relates to a paddy field wheel for a seeding machine, etc., and in particular,
To provide a lightweight and simple structure capable of reliably and well traveling on the surface of a paddy field by adding buoyancy.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a plan view of the entire seeding machine, which is a submerged direct sowing machine and has axles 1 and 1 on both sides of the mission case 5.
At the same time, the engine E is directly connected to the front of the mission case 5, a rear heel 6°6 is extended from the rear of the mission case 5, and a main float 7 is installed at the bottom of the fuselage long in the longitudinal direction. , with auxiliary floats 8°8 on both sides of the rear, each flow) 7, 8.8
A support frame 9 is pivotally supported on the lower side of the bundle 6, and a compression spring (not shown) is interposed between the front upper surface of the main float 7 and the lower surface of the mission case 5. The structure is such that the seed rice fed out from the sowing machine 10 mounted above each of the rice fields can be directly sown onto the rice field through the float.

Wheels are attached to the axles 1, 1, respectively, and the wheels are made by joining two synthetic resin wheels A,
Short cylindrical boss parts a, a formed at the center of A are fitted into a metal barrel 2 that can be fitted onto the axle 1, and the parts of both wheel bodies A, A on the peripheral side of the boss parts a, a are fitted in a circular direction. Hollow bulges 11 and 11 that bulge out at regular intervals are formed so as to coincide with each other, and the peripheral edge 1 is joined to each other on the outer periphery of both wheels A and A.
A narrow rubber ring 4 is fitted to 2° 12, and the peripheral edge 12
．． Hollow lugs 3, 3 inclined in the direction of rotation are formed on both side surfaces of the two wheels A, A near 12, and a large number are formed at regular intervals in the circular direction, so that adjacent lugs 3,
Bicycle A in between 3 and 3.

The portion A is configured by forming through holes 13, 13.

By rotating both wheels, the aircraft can be driven into rice fields, but both wheels are made of synthetic resin and have 3 lugs.
Since the hollow bulging portion 11 has a bulging hollow structure, buoyancy can be imparted, and while the lugs 3 exert a traction force, the outer rubber ring 4 bites into the rice field, making it possible to run on the surface of the river.

When running on the road, the rubber ring 4 is in contact with the ground, allowing the vehicle to run on the road without making noise.

Each float Otsu 8.8 slides on the surface of the paddy field while being towed by the side wheels, and the seed rice fed from each sowing device 10 can be directly sown into the paddy field.

In this way, the present invention combines the synthetic resin wheels A, A, and fits the center boss part a of both wheels A, A into the metal sleeve 2 for inserting the axle 1, Hollow lugs 3, 3 inclined in the direction of rotation are bulged at regular intervals on both side surfaces near the peripheral parts 12 and 12 of the two wheels A, A, so that the entire wheels A, A are Because it has a combined structure by combining synthetic resins, the wheel can be made lightweight, and deformation due to external force can be sufficiently prevented by the combination, and it has sufficient strength to withstand the load, and the periphery of the wheel is By providing the hollow lug 3 that is inclined in the provided rotation direction,
Since the lugs 3 play the role of auxiliary ribs, the strength of the wheel body can be further increased.In addition, since the lugs 3 are hollow and tilt in the direction of rotation, the hollow portion can provide buoyancy. The slanted lugs can exert sufficient traction force on the rice field surface, ensuring good running on the rice field surface.Furthermore, since the lugs 3 are hollow and bulging, the wheel body A The parts other than the lugs 3, etc., can be formed narrowly, and the wheels formed wide during paddy field work will push mud from the rice field sideways, suppressing paddy, etc. that have already been sown. It has excellent features such as not being washed away.
