2. Description of the Related Art Conventionally, for cultivating paddy rice and upland crops,
There are a transplanting method in which seedlings are made in a nursery box and transplanted in the field, and a direct sowing method in which seeding is directly performed in the field. As a porting method,
For example, it is generally known that a seedling made in a nursery box is placed on a seedling stand of a rice transplanter (rice transplanter), and the seedlings of the planting device scrape each seedling one by one to plant it in the field. The following are disclosed as planting nails for rice transplanters. Japanese Unexamined Patent Publication No. 5-15216 (hereinafter, referred to as "A") is a planting claw for a rice transplanter having a pair of left and right bar-shaped claws, and has a vertical cross section orthogonal to the longitudinal direction of the claws. , The lower surfaces of the pair of claw portions are formed in the inverted V-shaped inclined surfaces, and the outer side surfaces of the pair of claw portions are formed into flat surfaces along the moving direction of the claw portions. A planting claw for a rice transplanter, which is formed so that the corner formed by the lower surface and the outer surface is an acute angle, and the tip of the corner is located at the outermost part of the pair of claws. Is disclosed. JP-A-10-327
Japanese Laid-Open Patent Publication No. 630 (hereinafter, referred to as “B” publication) discloses a transplanted nail which is composed of a claw portion and a mounting portion having a U-shaped cross section continuous with the claw portion, and which is mounted by inserting the mounting portion into the nail case of the planting portion. Disclosed is a transplanted nail in which a connecting portion between a claw portion and an attachment portion is closed by an inclined surface that is inclined toward the toe side on the lower surface side.

As the direct sowing system, the traveling machine body of the rice transplanter and the working equipment mounting device are used as they are, and a flooded direct seeding machine in which the planting part is removed and the direct seeding device is mounted on the working equipment mounting device is used. It is known that seeds are directly sown in a field, and the following is disclosed. Japanese Patent Application Laid-Open No. 11-18515 (hereinafter referred to as “Ha”) provides a guide body for guiding a gel-coated seed or a seeded gel medium to a seedling intake on a seedling mounting table of a rice transplanter, and a gel is provided at the seedling intake. There is disclosed a direct seeding machine in which a sandwiching body for sandwiching a coated seed or a seeding gel medium is provided, and a gel-coated seed or a seeding gel medium is seeded with a planting nail. In recent years, a seed sheet (seed mat) in which seeds are attached to a sheet of paper or the like is placed on a feeding section that is newly attached to a seedling placing stand of a rice transplanter, and a predetermined amount of each seed sheet is scratched with a planting claw of the rice transplanter. Direct sowing method to take and plant in the field (hereinafter,
2) is disclosed.

[0004]

However, the conventional planting claws of the rice transplanter described above are used in such a manner that the seedlings placed on the seedling mounting table of the rice transplanter are scraped off by a predetermined amount or a gel-coated seed or a seeding gel medium is used. Since the purpose is to sandwich the seed mat, the seed mat embedded with the seed is placed on the seedling stand of the rice transplanter and the seed mat is scraped by a predetermined amount, which has the following problems.

When the direct seeding method of No. 2 is performed with the planting claws (transplanting claws) of the A and B publications and the seed mat placed on the seedling mounting table of the rice transplanter is scraped off, the tip of the planting claws is removed. Since the claw portion is formed in a bifurcated shape consisting of a pair of rods, etc., the seed mat block scraped from the bifurcated gap before the seed mat block scraped with the planting nail is planted in the field, Drops in the field and lacks direct sowing performance. Also, the seed mat cannot be cut off accurately in the bifurcated gap of the planting claw, and the seed mat is cracked or cracked at the part that hits the gap, so the amount of seed mat scraped The seeding amount is not uniform and the seeding accuracy is poor.
Furthermore, since the scraping surface of the seed mat scraped with the planting nail becomes uneven, the scraping surface is easily caught on the seedling mounting table surface, and the seed mat cannot be smoothly moved to the planting nail side. Lack of mat feeding performance and easy to cause troubles during direct sowing work.

When the seed mat is placed on the seedling placing table of the rice transplanter and the seed mat is scraped off by the planting claw like the No. 2 planting claw of the Ha publication, the seed mat cannot be scraped uniformly. At the same time, the scraped seed mat cannot be held securely by the planting claw, and the seed mat scraped off before planting the scraped seed mat easily falls from the planting claw, resulting in poor seeding performance. .

[0007] The present invention solves the above-mentioned conventional problems. The seed mat placed on the seedling placing table of the rice transplanter can be reliably scraped by a fixed amount, and the scraping surface of the seed mat is substantially linear. The seed mat can be moved smoothly on the seedling stand, and
An object of the present invention is to provide a scraping claw that can hold and carry a scraped seed mat block (seed block) without dropping it until it is planted in a field.

Things are used. The thickness of the scraping blade portion and the cutting portion is preferably 0.5 mm to 1.5 mm.
As the thickness becomes thinner than 0.5 mm, the durability of the scraping blade part and the cutting part tends to deteriorate, and it is difficult to form the inclined surface at the tip part of the scraping blade part and the cutting part. . Further, as the thickness of the seed mat becomes thicker than 1.5 mm, the seed mat is scraped off by squeezing it with the scraping blade part or the cutting part, so that the scraping surface of the seed mat is uneven, and the scraping surface of the seed mat is hard to be smooth. In addition, when the seed mat is scraped, the seeds tend to be crushed by the scraping blade portion or the cut portion. Also,
The length of the cut-off portion in the direction substantially perpendicular to the longitudinal direction of the scraping claw is preferably longer than the thickness of the seed mat. As a result, the seed mat can be reliably cut off at the cutting section. Further, a cutout portion having a substantially U shape, a substantially semicircular shape, a substantially semielliptical shape, or the like may be formed at a front end portion of the cutout portion on the front end side of the scraping blade portion.

The mounting part consists of a plate-shaped one or a rod-shaped one that is extended to the other end side facing the tip of the scraping blade part, such as a screw of the planting claw mounting part of the conventional rice transplanter. It is formed into a shape that can be attached to a planting claw mounting portion of a conventional rice transplanter, such as a mounting hole formed according to a mounting tool.

Further, the cut-off portion may be formed so as to be inclined outward from the vertical lower side of both sides of the scraping blade portion as the distance from the scraping blade portion increases. Thereby, after cutting the seed mat at the tip of the cutout portion, the seed block can be inserted while being compressed into the scraping portion surrounded by the scraping blade portion and the cutout portion along the inner wall of the cutout portion. Therefore, the seed block can be securely held in the scraping portion by the restoring force of the seed block, and the seed block is scraped until the seed block is moved to the field by moving the scraping claw and the seed block is planted in the field. It can be prevented from falling from the part. In this case, the seed block can be securely held in the scraping section by compressing the seed block between the facing cutaway sections, and the cut surface of the seed mat cut by the cut section is large in the thickness direction of the seed mat. It is preferable to incline the cutout at an angle that does not incline.
