The seedling receiving plate holding mechanism is configured to fix and hold the side end member (7a) on the rear frame (315) by screwing the bolt (7b) into the screwing portion (318) in which the screw hole is formed. The multi-row mat seedling transplanting device of the seedling transplanting machine according to claim 1 or 2 configured as described above.
In the invention of claim 4, the outer strip portion (315a) of the rear frame (315) is foldable inward, and the rear end of the outer strip portion (315a) of the folded rear frame (315) is folded. The multi-row mat seedling transplanting device for a seedling transplanting machine according to any one of claims 1 to 3, wherein the seedling transplanting device is located on the rear side of the rear end of the outer strip portion of the seedling tank (6). .
The invention according to claim 5 is provided with a lock portion (341) for fixing the folding portion for folding the planting mechanism of the outer strip portion from the folded state and performing the planting operation, and fixing by the lock portion (341). The planting depth adjustment mechanism and the seedling removal amount adjustment mechanism are switched to the setting at the time of storage in conjunction with the release of the planting, and the planting depth adjustment mechanism and seedling removal amount adjustment mechanism are interlocked with the fixing by the lock portion (341). The configuration is restored to the original setting, and the planting depth adjustment mechanism storage detection sensor for detecting that the planting depth adjustment mechanism is the setting at the time of storage, and the seedling amount adjustment mechanism are the settings at the time of storage. Seed removal amount adjustment mechanism storage detection sensor for detecting the seedling tank, the seedling tank left and right center position sensor for detecting that the seedling tank (6) is in the storage position at the left and right, and fertilization hose storage for detecting that the fertilization hose is in the storage position A position sensor, When any of the above sensors is not set to the storage position or is not in the storage position even though the fixing by the lock portion (341) is released, it corresponds to each sensor that is not detected. The multi-row mat seedling transplanting device for a seedling transplanting machine according to any one of claims 1 to 4, wherein the alarm is generated in a different form.
