The seedling guide tube 4 is connected to the bottom of one side of the turntable 31. Except for the position above the seedling guide tube 4, the bottom of the seedling storage cylinder 32 is provided with a support guide rod 33. The support guide rod 33 is mounted on the frame 1. The drive shaft 34 is mounted on the frame 1 and is connected to the turntable 31. The drive shaft 34 is connected to the second driven shaft 14 through chain drive. The tobacco seedlings are manually placed one by one into the rotating seedling storage cylinder 32. The bottom of the tobacco seedlings is supported by the support guide rod 33. The tobacco seedlings are in the seedling storage cylinder 32. As the turntable 31 rotates, when the seedling storage cylinder 32 rotates above the seedling guide tube 4, the tobacco seedlings lose the support of the support guide rod 33 and fall into the seedling guide tube 4 and enter the duckbill planting hopper 2.

[0018] Work process:

[0019] The duckbill planting hopper 2 rotates under the transmission of lever arm 15, connecting rod 16, and swing rod 17; the duckbill planting hopper 2 moves in a circular motion relative to the frame; tobacco seedlings are manually placed one by one into the rotating seedling storage cylinder 32, with the bottom of the seedlings supported by the support guide rod 33. As the turntable 31 rotates, when the swing rod 17 swings to its highest position, the duckbill planting hopper 2 aligns with the bottom of the seedling guide tube 4, the seedling storage cylinder 32 rotates above the seedling guide tube 4, the tobacco seedlings lose the support of the support guide rod 33, and fall into the seedling guide tube 4 and into the duckbill planting hopper 2; when the duckbill planting hopper 2 is at its lowest point, the linear velocity of the duckbill planting hopper 2 relative to the frame 1 is similar to that of the tractor. When the traction speed is close, the relative speed of the duckbill planting bucket 2 with respect to the ground is relatively small. The duckbill planting bucket 2 completes the insertion into the soil. The second driven shaft 14 opens and closes the left duckbill 23 and the right duckbill 24 through the cam 26, the swing arm 27 and the steel cable 25. The duckbill planting bucket 2 opens and moves upward, leaving the tobacco seedlings in the tobacco pond. The surrounding soil rolls towards the tobacco seedlings to achieve soil covering. With the rotation, the left duckbill 23 and the right duckbill 24 close to complete one operating cycle. The duckbill planting bucket enables rapid planting of tobacco seedlings, improves planting efficiency, reduces the labor intensity of planting personnel, shortens the transplanting time of tobacco seedlings, reduces the water shortage of tobacco seedlings and substrate soil, ensures the freshness of tobacco seedlings, and effectively improves the survival rate of tobacco seedlings.
