に知られている。2. Description of the Related Art Conventionally, a block-type seedling is cultivated in a pot-type nursery device with a front and rear and a left and right sides, and this block-shaped seedling is stored in a seedling mounting table and a resistance rod is provided on the side better than the delivery section. When seedlings are sent out intermittently, one row of seedlings passes through the resistance rod and is sent out, and the seedlings of the seedlings in this front row are provided over the entire width of the upper side of the seedling table on the sending side. Then, the receiving part, which has a semicircular shape in plan view, is divided and received by the receiving body that is continuous in a corrugated form. A transplanter in which one strain is scraped off and planted in a field is already known from Japanese Patent Application Laid-Open No. 62-208208.

や倒れ苗を生じた。The known transplanter is supplied with the seedlings of the seedling block fed to the delivery section of the seedling placing table and holds the seedling block at the position without changing the relative position to the seedling placing table. You can do it. However, while the seedling table containing the seedlings moves laterally with a considerably steep posture toward the sending part, the apron that receives the bed soil is attached to the fixed frame so that it does not move laterally. Moves laterally at almost the same speed in synchronization with the lateral movement of the seedling placing table, but the lateral movement of the bed soil strongly pressed against the apron is delayed due to frictional resistance. Inclining in the direction of movement of the stand and the soil at the scraping end becomes slanted following the inclination of the seedlings, and as a result, the seedlings are cut or pushed down when the planting plant scrapes the seedlings. It caused spilled seedlings and fallen seedlings.

題を解決した。According to the present invention, an apron having a scraping port is provided at the lower end of a seedling table which is reciprocally moved in the lateral direction and is inclined downward in the delivery direction. In a transplanter in which the seedlings are invaded into the seedling mounting table from the intake and scraped one by one to be planted in the field, the stem or leaf of the seedling is contacted above the scraping opening of the apron. The above-mentioned problems were solved by providing a seedling guide body that suppresses lateral movement.

な苗葉移動抑制を行うことができる。[Function] When the seedlings with bed soil are stored in the seedling mount and the machine is run while driving the plant and the seed mount, the plant enters the seed mount through the scraping opening of the apron. The seedlings are scraped off one by one and planted in the field. At that time, the leaves and stems of the seedlings move laterally following the lateral movement of the seedling mounting table, but because the bed soil is pressed against the apron, it causes a delay in movement due to resistance, resulting in leaves and stems. Moves laterally in an inclined posture that leads the soil. When the leaves and stems approach the apron scraping opening, they contact the seedling guide body and are restrained from lateral movement. It will be in a vertical posture, the scraping edge of the soil will not be slanted, the plant will not cut the leaves and stems, and the plant will firmly sandwich the soil, Does not cause fallen seedlings. Further, when the apron is adjusted forward / backward, by adjusting the seedling guide body forward / backward, proper movement of seedling leaves can be suppressed regardless of the amount of scraping.

The attached body 15 ... Invades the scraping opening 18 of the apron 20 into the seedling placing table 16 to scrape the soil for one plant and plant it in the field. When the seedling placing table 16 reaches the lateral movement end, Similarly to the above, the delivery belt 17 is intermittently rotated to deliver the mat seedlings until the bed soil presses against the apron 20.

落して転び苗になったりすることがない。During such planting work, the seedling placing table 16 is in a forward tilted posture, and the floor soil is biased down by its own weight and its lower end surface is pressed against the apron 20 integral with the machine body. When the seedling mounting table 16 moves laterally, the delivery side end surface of the bed soil causes a transfer delay due to frictional resistance, while the leaves are received by the seedling holder 25 integral with the seedling mounting table 16, Seedling stand 16 without causing transfer delay
As a result, the leaf part has an inclined posture that precedes the floor soil, and the stepped scraping end of the floor soil causes the seedling to have an inclined posture. When the upper part is in the preceding deformed state, above the scraping port 18, the tip portion of the seedling guide body 2 has entered the seedling placing table 16.
Since 6 receives the leaf portion on one of its slopes and suppresses lateral movement, the direction of the seedlings is corrected to a direction substantially coincident with the rotation surface of the planting body 15 ... The end portion will also be kept in a normal shape, and when the planting body 15 scrapes off the ground soil, cuts leaves and stems, and the beak 15a scrapes and sandwiches the ground soil, the seedlings have an oblique posture. It will not be pinched by or will not fall off and become a seedling.

It can be performed. Furthermore, when the apron 20 is adjusted to move forward or backward in order to increase or decrease the amount of seedlings scraped by the planting body 15, if the seedling guide body 26 is moved forward or backward with respect to the support member 27 or 27a and set to an appropriate position, the seedling scraping will be performed. Regardless of the amount taken, it is possible to always correct the seedling posture.

い。According to the present invention, the apron 20 having the scraping port 18 is provided at the lower end of the seedling table 16 which reciprocates laterally and descends and slants toward the feeding direction, and the planting body 15 is scratched by the apron 20. In a transplanter in which the seedlings are invaded into the seedling mounting table 16 from the intake 18 and scraped one by one to be planted in a field, above the scraping opening 18 of the apron 20, seedling stems or Since the seedling guide body 26 that comes into contact with the leaf portion and suppresses lateral movement is provided, when the seedling mounting table 16 is laterally moved, the leaves and stems of the seedling are laterally moved in substantially the same state as the seedling mounting table 16. On the other hand, the bed soil is pressed against the apron 20 and receives a large resistance, which causes a movement delay, and as a result, the leaves have an inclined posture leading to the bed soil, but on the scraping opening 18 of the apron 20. The arranged seedling guide body 26 comes into contact with the seedling leaf and suppresses its movement. More direction Naemi is corrected in substantially upright posture from bed soil, planting body 15 ... it is the scraping port 1
When invading the seedling mounting table 16 from 8 and scraping off the soil, the leaves and stems of the seedlings are not cut, and the soil is broken and the seedlings are spilled or the seedlings are misplaced and the seedlings fall. Never.
