[0033] Before work, the position of the discharging sleeve 2905 is adjusted to be located directly above the inner cylinder 7. The seedlings to be transplanted are placed in each seedling throwing cone 2904. During work, the rotating shafts 2903 are driven to rotate, the transmission chains move, and the transmission chains drive the seedling throwing cones 2904 to rotate circularly. As the seedling throwing cones 2904 move, when the rollers 2907 installed thereon climb onto the discharging plate along the transition plate 2096, the half of the seedling throwing cone on the side where the roller 2907 is installed is opened, and the seedlings placed in the seedling throwing cone 2904 fall into the inner cylinder 7 below.

During work, the moving plate 8 and the outer cylinder 4 are pushed downward by the reciprocating driving assembly 9, the hollow cup motor 2 is started, and the outer cylinder 4 is driven to rotate and move downward, and the punching operation is performed. During the upward and downward movement, the inner cylinder 7 moves downward together with the outer cylinder 4 under the action of the spring 13, the sliding block 16 and the limiting cylinder 11. When the punching is completed, the hollow cup motor 2 is stopped or reversely rotated, the moving plate 8 and the outer cylinder 4 are pushed upward by the reciprocating driving assembly 9, and the inner cylinder 7 moves upward together with the outer cylinder 4 under the action of the spring 13 until the top of the mounting plate 15 contacts the limiting rod 14, the limiting rod 14 limits the upward movement of the inner cylinder 7, the inner cylinder 7 cannot continue to move upward, but the outer cylinder 4 continues to move upward under the action of the reciprocating driving assembly 9, so that the inner cylinder 7 moves downward relative to the outer cylinder 4, and the lower edge of the inner cylinder 7 pushes against the inner wall of the cone cylinder 6 downward, and the two halves of the cone cylinder 6 are driven to rotate around the hinge shaft under the ejection action of the inner cylinder 7 until they are opened to allow the seedlings to fall smoothly.
