JPH09308306A - Puddling cage rotor - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a puddling cage rotor capable of producing the buoyancy without changing the basic structure. SOLUTION: This puddling cage rotor is obtained by attaching a cylindrical unit 8, having the outer peripheral surface 8a formed as an outside diameter inscribed in an edge 7a on the lower side of a group of lugs 7, made of an expanded resin as a material and having fitting grooves 8b capable of entirely fitting a boss 5 and radial arms 4 formed in an inner lateral part in the interior of a rotor body 1 prepared by installing the lugs 7 at an interval in the circumferential direction in the clearance width between a wheel frame 2 on the inside supporting the boss 5 through the radial arms 4 on the central recessed side of a rim 3 and a wheel frame 6 on the outside composed only of the rim 3 from the outside direction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a car rotor for scratching a wetland field as an attachment for a small tractor.

[0002]

2. Description of the Related Art In the case of wetland and super-wetland subsiding, a float-type cage roll having a structure in which each rug itself is formed into an inner sky rather than a plate, and the total buoyancy of the lugs prevents settlement.
There is data. However, this conventional type changes the basic structure of the car rotor itself, and it takes time and effort to manufacture the car rotor, resulting in high cost. Actually, we haven't seen that level of diffusion.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional circumstances, and is a substitute basket basket rotor which provides buoyancy with a simple additional structure without changing the basic structure.
I will provide a.

[0004]

In order to achieve the above object, the present invention provides an outer side composed of only an inner wheel frame 2 bearing a boss 5 via a radial arm 4 on the side of a central recess of a rim 3 and an outer rim. In a car rotor main body 1 (with the same structure as the car rotor of the conventional structure up to this point), in which the lugs 7 are attached at intervals in the circumferential direction to the width of the wheel frame 6, the outer peripheral surface is provided inside. A cylindrical body made of a polyurethane foam material having an outer diameter 8a inscribed in the lower end edge 7a of the lug group 7 and a fitting groove 8b into which the boss 5 and the radial arm 4 are fitted in the inner side. 8 is a substitute basket basket rotor having a structure in which 8 is fitted from the outside.

Further, in the above construction, a polyurethane ho
This is a substitute basket basket rotor in which the columnar body 8 made of rubber material is formed in a length that is the full width of the interval between the inner wheel frame 2 and the outer wheel frame 5 of the rotor body 1.

[0006]

As described above, the present invention has the fitting groove 8b corresponding to the frame of the car rotor body 1 from the outside of the car rotor body 1 without changing the conventional basic structure. Since the cylindrical body 8 made of polyurethane foam is united, it is easy to manufacture and the manufacturing cost is low.

[0007] Now, when this substitute basket basket rotor is connected to a towing machine such as a small tractor to run in wetlands or super wetlands,
Since the specific gravity of the cylindrical body 8 made of polyurethane foam is small, buoyancy is generated in the rotor as a whole to prevent sinking, and smooth and efficient scratching can be performed. In the union method, the outer peripheral surface 8a has an outer diameter inscribed in the lower end edge 7a of the lug group 7 and a polyurethane groove having a fitting groove 8b in which the boss 5 and the radial arm 4 are fitted together is formed on the inner side portion. Since the cylindrical body 8 made of rubber material is fitted from the outside of the car rotor main body 1, the cylindrical body 8 surely meshes with the car rotor main body 1 to rotate integrally with the car rotor main body 1 to rotate the rotor itself. Does not interfere with. The cylindrical body 8 made of polyurethane foam can be easily attached / detached and replaced due to exhaustion and damage, and can have any specific gravity depending on the expansion ratio.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawings, reference numeral 1 designates a distance between an inner wheel frame 2 that supports a boss 5 via a radial arm 4 on the side of a central recess of a rim 3 and an outer wheel frame 6 consisting of only a rim. , A car rotor body 1 in which lugs 7 are mounted at intervals in the circumferential direction. 8 is an outer peripheral surface 8a of the lower end edge 7 of the lug 7 group.
An outer diameter is inscribed in a, and a fitting groove 8b into which the boss 5 and the radial arm 4 are fitted is formed on the inner side portion.
It is a cylindrical body made of a polyurethane foam material having a foaming rate of 25 times and having a length of about 3/4 of the total length of the car rotor body 1.
The present invention is a substitute basket car rotor having a structure in which the cylindrical body 8 is inserted into the frame of the car rotor main body 1 from the outside and is fitted in the fitting groove 8b.
