when the device is used for throwing seedlings, the overturning shaft (141) overturns along the connecting shaft of the shell (a 13), the contact plate (142) overturns out of the auxiliary groove (a 11), when the seedlings are thrown, the seedlings are contacted with the contact plate (142), the contact shaft (145) is contacted with the seedlings, the contact shaft (145) rotates along the movable shaft of the contact plate (142), the direction of seedling slipping is planned, when the structures such as branches and leaves of the seedlings are contacted with the mounting body (146), the rolling ball in the mounting body (146) rolls along the driving direction of the seedling contact end, the friction force between the seedlings and the adhering surface is reduced, meanwhile, when the seedlings are contacted with the lower pressing block (143), the lower pressing block (143) slides along the lower pressing cavity (144), the impact force generated when the seedlings fall and contact and collide with the contact plate (142) can be consumed, the connecting ball on the lower pressing block (143) rolls along the driving direction of the seedlings, when the device needs to guide the seedlings into the guide pipe (2 d), the connecting rings on the two sides of the extension shaft (a 3) slide along the cylinder of the extension column (a 6), the connecting movable shaft of the traction shaft (a 5) and the adjusting shaft (a 7) rotates along the extension column (a 6), so that the opening and closing block (a 4) is pulled, the opening and closing block (a 4) is overturned along the movable shaft of the placing device (a 1), the opening of the feeding pipe is opened, the seedlings slide out from the opening, the overturning structure is arranged outside, and the root structure of the seedlings cannot be dragged with the opening and closing assembly structure when the seedlings slide out, causing damage to the roots of the seedlings;

when seedlings are placed in the feeding pipe, the offset shaft (124) slides along the offset rod (125), the attaching device (123) is pushed out of the device body (121) by means of a connecting rod on the pushing body (122), the rotating shaft (236) rotates along the rotating column (231) and surrounds the periphery of seedling branches and leaves, movable space for seedling cultivation is reduced, when the seedlings are rocked due to rotation of the feeding structure, the moving block (234) slides along the moving column (233), one end, provided with a hollow cavity, of the moving block (234) faces towards the seedlings, the seedlings collide with the moving block (234) when rocked, energy is consumed by collision of the moving small balls inside the moving block (234), when the seedlings are attached to the attaching cavity (232), collision acting force acts on the attaching cavity (232), the arc-shaped shaft on the attaching cavity (232) can be pushed to extrude the extruding block (235), energy consumption is achieved, and the soft rubber layer at the attaching end of the attaching cavity (232) and the moving block (234) can deform due to collision impact force, and no loss of the seedlings can be caused.
