Claims

[Claims for Utility Model Registration] A transfer device 22 that horizontally and intermittently transports a seedling box 4 holding a large number of seedlings 20 vertically and horizontally, and a push-up mechanism 43 that pushes out one horizontal row of seedlings 20 upward from the bottom of the seedling box 4.
Then, a seedling pushing mechanism 79 pushes out one row of pushed up seedlings 20 from above the pushing up mechanism 43 in the same direction as the transfer direction of the seedling box, and a seedling holder 63 that holds the pushed out seedlings 20 is arranged in an endless shape. It has a lateral transport mechanism 57 which performs horizontal intermittent lateral transport in a direction intersecting the seedling box transport direction and sequentially drops the seedlings 20 from the seedling holder 63 at the tip in the lateral transport direction to the transplanting section 65. The seedling holder 63 has a side wall portion 73 that can support the side surface of the seedling 20, and a base end 72b that supports the bottom surface of the seedling 20 and allows the tip 72a on the pushing-up mechanism 43 side to freely rotate downward. Bottom wall portion 7 pivoted to side wall portion 73
2, this bottom wall portion 72 is located below the seedling 20 at the uppermost position, and from the time the seedling 20 is received until it falls, the bottom wall portion 72 is positioned below the tip 72 of the seedling 20.
An automatic seedling feeding device for a transplanter, characterized in that a guide body 75 is provided to be supported in a downwardly inclined manner from a to a base end 72b.
