Description

[Detailed Description of the Invention] The present invention relates to a seedling planting device comprising a main body casing having a seedling stand, provided with seedling planting claws, and a float provided at the bottom of the casing.

Generally, this type of seedling planting device is used by being attached to the front or rear of a machine body equipped with drive wheels. In addition to leveling the soil surface, seedlings are planted into the soil using planting claws. By the way, when planting a seedling with this planting claw, the root of the seedling is held between the planting claw and then buried in the soil, and then the root of the seedling is released from being held by the planting claw and the seedling is removed. This is done by pulling the seedlings out of the soil, but when the planting claws release the grip on the root of the seedling, the soil on both sides of the root of the seedling is raked away by the planting claws, causing the seedling to rise to the surface. The seedlings were wobbling and falling over, making it very difficult for the seedlings to take root.

The present invention was devised to solve the above-mentioned problems, and its purpose is to plant the roots of the seedlings in soil with a leveled surface using a float, and to When removing the planting nail from the soil, firmly compact the soil at the root of the seedling planted in the soil to prevent the seedling from floating or lodging.
To provide a seedling planting device at a low cost that can reliably prevent the occurrence of so-called floating seedlings and maintain the planting posture of seedlings in an extremely good manner.

Embodiments of the present invention will be described below based on the drawings.

The seedling planting device, which is generally indicated by number 1 in the figure, is
Main body casing 1 with two planting claws 12, 12
1, a seedling stand 13 mounted on the upper part of the main body casing 11, and a float 14 serving as a leveling member supported at the lower part, and plate-shaped fins 15, 15 extend from both sides of the float 14. It has been formed.
In addition, the seedling planting device 1 includes two drive wheels 21, 2.
1, and a control handle 3 is connected to the rear of this seedling transplanting device 1 to form a so-called rice transplanter. the drive wheel 21,
21 are interlocked and connected, and the machine body 2 is configured to run by driving the drive wheels 21, 21 by the prime mover 22. On the other hand, the prime mover 22 and the planting claw 12 are interlocked and connected, and the prime mover 22 is configured to travel by driving the drive wheels 21, 21. The planting claws 12 are driven to grab the seedlings on the seedling stand 13 and bury the roots of the seedlings in the soil. It should be noted that a rice transplanter having such a structure is already known, and a detailed explanation thereof will be omitted.

However, the present invention uses the rice transplanter as described above.
As shown in FIGS. 2 to 4, the float 14
The lower wall at the side of the seedling planting section by the planting claws 12 is bulged downward, extends in the seedling planting direction, and is inclined so that the rear end in the planting direction is directed toward the seedling planting section side. The earthen body 4 is integrally formed.

The rice transplanter equipped with the seedling planting device of the present invention is constructed as described above, and as the machine body 2 moves, the fins 15, 15 of the float 14 are used to level the soil surface in the paddy field. Together with the planted nail 12,
12 grips the roots of the seedlings on the seedling stand 13 and buries them into the soil, then releases the grip of the roots of the seedlings by the planting claws 12, 12, and removes the planting claws 12, 12 from the soil. By pulling out the seedlings, the seedlings are planted, and at this time, the soil is firmly compacted around the roots of the seedlings planted in the soil by the action of the soil cover 4. That is, when the planting claws 12, 12 release the grip on the root of the seedling as described above, the soil at the root of the seedling is scraped away as shown in FIG. Guided by the slope of the soil support body 4, it moves toward the seedling as shown by the arrow in Figure 6, and can forcibly crush the space around the seedling, thereby firmly fixing the root of the seedling in the soil. can be done.

In particular, according to the present invention, even if the field is hard or there is a lot of straw or garbage in the soil, the soil can be reliably planted using the soil cover 4.

As explained above, the seedling planting device according to the present invention is
The lower wall of the float at the side of the seedling planting part by the planting claws is bulged downward, extends in the seedling planting direction, and is sloped so that the rear end in the planting direction faces toward the seedling planting part side. Since the body is integrally formed, the root part of the seedling is held between the planting claws and the seedling is buried in the soil, and then the planting claws are released from holding the root part of the seedling, and the planting claws are removed from the soil. When pulling out the soil at the root of the seedling, it is removed by the planting claws, but the soil between the seedling and the soil support is pushed back between the seedlings and the space around the root of the seedling is forcibly filled. By crushing it, you can firmly and reliably fix the root part of the seedling in the soil.
Therefore, the planted seedlings will not float up or fall down due to the waves caused by the movement of the aircraft, and the seedlings can be planted extremely reliably and in a good planting posture. It is.

In particular, since the above-mentioned earthwork body was integrally molded by bulging the lower wall downward when forming the float, it was necessary to specially form the earthwork body separately from the float and attach the earthwork body to the float. Since there are no floats, there are problems with retrofitting a separate body from the float, such as difficulty in bending the body and setting and adjusting the installation to the float.
The earthwork body may be deformed or damaged due to the load caused by the earthwork or collision with the concrete at the ridge during turning.
This solves problems such as the angle at which the float is attached to the float changes and the direction of the bank changes, causing the planted seedlings to be pushed down by the bank, or not being able to move the bank properly. The soil between the seedling body and the seedling body can be reliably pushed back between the seedling parts by the soil body formed integrally with the float.

In addition, in order to integrally mold the earth body with the float,
Since it is only necessary to devise a mold for molding the float, the cost and man-hours for materials, processing, and installation of separate earthwork bodies and fixtures can be omitted, and the float can be provided at an extremely low cost.
