Through the pair of duckbill plates 731 driven synchronously, after the pneumatic clamps in the seedling drop assembly 7 clamp and take out the seedlings, the seedlings are released to fall to the bottom along the open channel 71, and then, by coordinating the movement stroke of the whole machine, the bottom duckbill plate 731 is driven to open by a cylinder, so that the seedlings fall into the slots with a fixed spacing, and the design of wide top and narrow bottom allows the seedlings to fall in the middle. The piston rod end of the cylinder is rotatably connected to the transmission shaft on one side of the single duckbill plate 731, and then when the single duckbill plate is driven to rotate, under the coordinated action of the synchronous gear 733, the other duckbill plate 731 is synchronously opened or closed.
