Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leveling float of a seedling transplanter.

[0002]

2. Description of the Related Art In a leveling float of a seedling transplanter,
Conventionally, as shown in, for example, Japanese Utility Model Laid-Open No. 1-60623, a plurality of components are formed in the planting width direction, and a notch for planting is formed at the rear of each leveling float.

[0003]

In the transplanter used for planting rice seedlings, the spacing between the seedlings is relatively large, so that even with the above-mentioned plural float configuration, the width of each leveling float can be sufficiently secured. Therefore, the ground contact stability is good, and the soil leveling action can be performed. However, there was a defect that the grounding stability was poor and the leveling action was insufficient. Therefore, it is conceivable to form an integral structure over the entire width of the strip and to form the bottom surface as a flat surface over the entire width, but in this case, since the contact width is wide, the amount of mud pushed out to the side is increased, There are adverse effects such as pushing down seedlings already planted and ruining the field. The present invention
The purpose is to eliminate the above disadvantages by rational structural improvement.

[0004]

The present invention is characterized in that a seedling planting device is connected to a rear portion of a traveling machine body, and a wide leveling float is provided below the seedling planting device over substantially the entire planting width. Then, on the bottom surface of the leveling float, a recessed portion gradually narrowing toward the rear side from a wide state including a portion corresponding to the running traces of the left and right wheels of the traveling body at the front end thereof is formed to an intermediate position in the front and rear. The bottom of the leveling float on the rear side of the concave portion is formed as a flat surface over the entire width.

[0005]

[Function] The raised mud at the place where the field scene is roughened by the passage of the wheels of the traveling machine enters the recess formed at the center in the width direction to prevent the soil from flowing out to the lateral side. Is lost in the middle of the front and rear, and the rear bottom surface is formed as a flat surface over the entire width, so that the mud introduced and guided is effectively buried back into the concave portion of the wheel passing trace by this flat surface, and there is no mud pushing securely. It can perform a natural leveling operation.
In addition, since the seedlings are provided on a flat surface over the entire width, the seedling planting apparatus has excellent grounding stability.

[0006]

[Effect of the invention] Therefore, the entrance is made to fill the inside of the float with the wide recessed portion and backfill the mud,
It has become possible to provide a grounding float capable of stably supporting the ground while sufficiently preventing the mud flow to the outside and sufficiently exerting the leveling action of the mud surface.

Embodiments will be described below with reference to the drawings. FIG.
Shows a transplanting machine for rush seedlings. This seedling transplanter is configured by connecting a seedling planting device 2 to a rear portion of a traveling machine body via a link mechanism 1. The seedling placement device 2 removes seedlings from a seedling rest 4 that reciprocates and moves laterally with respect to a planting transmission case 3 combined with a frame that is connected to the link mechanism 1, and a seedling outlet 5 at the lower end of the seedling rest 4. It comprises a plurality of planting mechanisms 6 for taking out the plants one by one and planting them in the field, a leveling float 7 for muddy leveling, and the like.

As shown in FIGS. 1 to 3, the leveling float 7 is integrally formed on the front side with almost the entire planting width, and on the rear side, the planting operation by each planting mechanism 6 is permitted. A notch 8 is formed so as to be narrow enough to enter between the planting strips. And leveling float 7
On the bottom surface, a recessed portion 10 gradually narrowing toward the rear side from a wide state including a portion corresponding to the running trace of the left and right wheels 9 of the traveling body at its front end portion is formed to a front and rear halfway position, The bottom surface 11 of the leveling float 7 on the rear side of the recess 10 is formed to be flat over the entire width. The float bottom surface 12 of the recessed portion 10 is inclined so as to be higher toward the front end and lower toward the rear, so as to effectively level up the muddy swelling of the wheel running trace. Further, by forming the front and rear middle portions flat over the entire width, it is possible to reliably backfill the mud, effectively perform the leveling action on the planting location, and stabilize the ground support of the seedling planting device 2. .
