SOLUTION: This apparatus is so designed that, there is provided a wide machine frame 1 doubling as a sheathing case 1a equipped with link levers 3, 4, 5 to the three-point hitch of a tractor at the center and also equipped with a power transmission section connected to a power outlet; a transverse rotational shaft 6 is set up via the main gear 2a of the power transmission section, and horizontally rotatable swing raking tine devices 9 are multiply mounted via turning gears 7, 8 on the transverse rotational shaft 6 through power transmission so that the swing raking tine devices 9 adjacent to each other are mutually subject to inside rotation; and the swing raking tine devices 9 are mounted with rod-like swing tines 11 via universal couplings at intervals of the lower surface angles of the disc frames 10 so that the swing angles are in free directions but limited by the side frames 10a of the disc frames 10.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a tractor-traction type planting leveling device for planting before rice transplanting in rice cultivation.

[0002]

2. Description of the Related Art Planting and scraping with a ground cutter using a rotor claw is an automatic operation.
There is a risk that miscellaneous materials will float. Instead, the replanting leveling work, in which the planting surface is roughened by hitting the planting surface with two plates at a predetermined interval by hand (two persons), eliminates the above-mentioned disadvantages and reduces the number of floating seedlings caused by subsequent rice transplanting. However, the labor is extremely large and the work efficiency is poor.

The inventor of the present invention has previously proposed a tractor-tow-type land transplanting leveling device for automating the planting leveling operation using two plates (Japanese Patent Application No. 7-10167).
3). However, the structure is disadvantageous in that it is mechanically complicated and the production cost increases, and it is far from the general popularization type.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has a simple configuration in which a tractor-traction type, multiple mounting of a shaking claw device that rotates horizontally in the width direction is used. Provided is a leveling device for transplanting that can automatically perform a uniform continuous operation with a simple structure.

[0005]

In order to achieve the above object, a tractor-towed-type planting leveling device according to the present invention is provided with connecting rods 3, 4, 5 for connecting a tractor to a three-point hitch at a central portion. In addition, a wide machine frame 1 including a power transmission unit 2 connected to a power outlet is provided. Then, a horizontal rotation shaft 6 is installed via the main gear 2 a of the power transmission unit 2, and a horizontal rotation of the shaking claw device 9 is connected to the horizontal rotation shaft 6 via the direction change gears 7, 8 in multiples. Installing. The shaving claw device 9 includes the disc frame 1
A swing claw 11 is attached to the disc frame 10 so that the swing angle is restricted by the side frame 10a of the disc frame body 10.

The horizontal rotation direction of the multiple shaking claw device 9 is as follows.
There can be several modes for each shaving claw device 9 (inner rotation next to each other, inner rotation in two places, inward direction at the center, etc.). It is desirable that the power be transmitted as described above in order to smoothly introduce dust into the inside as described later (FIG. 7).

[0007]

Operation and effect of the present invention To use the device of the present invention,
The connecting rods 3, 4, 5 are connected to the three-point hitch of the tractor, and the power transmission unit 2 is connected to the power outlet PTO of the tractor.
The tractor is towed in a water field that has been previously plowed and supplied with water (FIG. 8).

[0008] Then, as shown in FIG. 7, each of the shaving claw devices 9 rotates according to the transmission method, and accordingly, the shaking claw 11 having directional flexibility is adjusted by the side frame 10 a of the disc frame 10 to set the swing angle. It is swung in the centrifugal direction while being restricted (FIGS. 5 and 6).

[0009] Therefore, by this continuous operation, miscellaneous substances including rice plants and garbage are sufficiently stirred by the swinging claws 11 of the shaving claw device 9, and are strongly entrained and pushed into the soil, and the nails are strongly promoted. Even if there is a rotating tentacle caused by the swelling, there is no danger of floating rice plants and miscellaneous materials, and only mud comes up. As a result, a uniform planting surface is formed, and there is almost no floating seedling due to rice transplanting later, leading to high yield. Since the tractor is traveling, the work efficiency is high, and there is almost no mud splash and no water splash during the work as well as labor saving. The structure is simple, the weight can be reduced, and the manufacturing cost can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An outer casing 1a having a connecting rod 3, 4, 5 for connecting a tractor to a three-point hitch at the center and a power transmitting section 2 connected to a power outlet. A wide machine frame 1 is provided. A horizontal rotation shaft 6 is erected through the main gear 2 a of the power transmission unit 2, and the horizontal rotation shaft 6 is rotatably mounted on the horizontal rotation shaft 6 via directional change gears 7 and 8.
Are transmitted in such a manner that adjacent shaking claw devices 9 are rotated inwardly to each other, and are mounted in multiple units. The shaving claw device 9 is freely swingable through the universal coupling 12 at the lower surface angular interval of the disk frame 10 and the swing angle is restricted by the side frame 10a of the disk frame 10.
It consists of.

The shape of the shaving claw device 9 can be any one of a plate-shaped one (FIG. 1), a rod-shaped one (FIG. 2), and a general spiral one, through a universal joint that fits them. Applicable.
