DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling transplanter for taking out one plant of onion or the like from a seedling tray and planting the seedling in a field. The present invention relates to a configuration of a seedling supply device provided with a seedling regulating rod for preventing tangling of seedlings at the time.

[0002]

2. Description of the Related Art Conventionally known seedling transplanters are self-propelled by crossing ridges with left and right running wheels as disclosed in, for example, JP-A-7-8029 and JP-A-9-28130. The engine, the transmission case,
A seedling supplying device, and a seedling supply device for supplying pot seedlings arranged in a matrix on a seedling tray, wherein the seedling planting device holds a seedling to be transplanted at the tip of a vertically swinging arm, and And a transfer mechanism including a transplanting cup for transplanting to the seedling feeding device, and a transfer mechanism including a seedling removal claw or the like for transferring a pot seedling in the seedling tray transferred downwardly from the seedling supply device to the transplanting cup. There was what was constituted by.

[0003] After piercing the pair of left and right seedling removal nails from above into the seedbed soil portion of the pot portion of the seedling tray, the left-right distance between the tip sides of the pair of seedling removal nails is reduced to grasp the seedling soil. ,Pull up. Subsequently, the cycle of releasing the pot seedlings above the transplanting mechanism was repeated.

[0004]

In this case, in the seedling supply device, the seedling tray is transferred downward and inclined downward from the transfer mechanism. There is a problem that the seedlings are entangled with the above-mentioned seedling take-out claws descending from above, so that the seedlings cannot be taken out and transferred smoothly and accurately, and also damage the seedlings. was there.

[0005] Therefore, in the conventional seedling transplanter, the seedling that moves the seedling to the side opposite to the inclination is located at a position below the transfer mechanism and at a height where the free end (tip) of the seedling passes. There was one in which a leaf holding rod was arranged, but the seedlings in a large number of pot seedlings on the upstream and downstream sides in the transfer direction of the seedling tray were entangled with each other at the location of the seedling holding rod, and instead the seedling removal and inheritance were performed. There was a problem that the number of defects increased.

In particular, in the case of onion seedlings and the like, the seedlings are slender and easily fall down in an inclined direction, so that the seedlings are entangled with each other.

The present invention has been made to solve this problem, and the upper end side of a seedling rising from a potted seedling in a seedling tray transferred in a downwardly inclined shape is defined as an upstream side and a downstream side in the transfer direction of the seedling tray. It is an object of the present invention to provide a seedling transplanter capable of eliminating entanglement of seedlings by regulating at a number of places with the side, and facilitating removal and transfer of seedlings.

[0008]

According to a first aspect of the present invention, there is provided a seedling transfer apparatus for a seedling transplanter, wherein a self-propelled body is driven by left and right running wheels by power from an engine. A seedling supply device for feeding potted seedlings arranged in a matrix on a seedling tray, and a transplanting device comprising a transplanting cup for holding the seedling to be transplanted at the tip of the vertically swinging arm and transplanting it to a field. A seedling transfer machine comprising a mechanism and a pair of seedling extraction claws or the like for transferring a pot seedling from the seedling supply device to a transplanting cup. The seedling supply device is configured to move in a downwardly inclined shape toward the inheritance mechanism, and the seedling supply device regulates the vicinity of the upper end of the seedling rising from the pot seedling so as to be kept away from the inheritance mechanism. The rod is obtained by arrangement number at appropriate intervals in the transport direction of the seedling tray.

According to a second aspect of the present invention, in the seedling supply apparatus for the seedling transplanter according to the first aspect, the seedling regulating rod is configured to be adjustable in height with respect to an upper surface of a seedling tray. is there.

[0010]

According to the first aspect of the present invention, each of the seedling regulating rods is appropriately separated from the upper surface of the seedling tray and arranged so as to extend in a direction perpendicular to the transfer direction of the seedling tray. In addition, they are arranged at appropriate intervals in the transfer direction of the seedling tray. Therefore, of the pot seedlings moving along the transfer direction, the vicinity of the upper end of the seedlings rising from the pot seedlings on the upstream side of the transfer is restricted from falling by the seedling control rods on the upstream side in the transfer direction, In the transfer direction, the vicinity of the upper end of the seedling that rises from the pot seedling is regulated so that the vicinity of the upper end of the seedling that rises from the pot seedling does not fall to the downstream side in the transfer direction with the seedling control rods that are arranged at appropriate intervals each time it moves. The seedlings from the pot seedlings along can be separated by a small number of seedling control rods to control the fall, and the phenomenon that many seedlings gather and entangle can be eliminated. And the transfer of the seedling to the transplantation mechanism at the location of the transfer mechanism of the seedling can be performed smoothly.

According to the second aspect of the present invention,
Since the height of the seedling regulating rod can be adjusted with respect to the upper surface of the seedling tray, the seedling regulating rod can be set at an optimum position in accordance with the height of the seedling, and the entanglement of the seedling is prevented. This has the effect of being able to be at the optimum height position.
