Both the outer sides of the two operating lead screws 22 are fixed with chain wheels 23, and the outer sides of the two chain wheels 23 are meshed with a chain ring 24. By externally controlling the rotation of one of the chain wheels 23, the synchronous rotation of the two operating lead screws 22 can be controlled, so that the synchronous lifting of the two scissor-type lifting frames 21 can be controlled, and thus the height adjustment of the tobacco leaf shearing support frame 3 can be completed through the lifting adjustment mechanism 2, and the height adjustment of the tobacco seedlings to be trimmed can be completed through the height adjustment of the tobacco leaf shearing support frame 3, which is convenient for shearing tobacco seedlings of different heights.

[0022] The tobacco leaf shearing support frame 3 includes a support 31, a support seat 32, an L-shaped plate 33 and a roller 34. The support 31 is installed at the top end of the lifting adjustment mechanism 2. A plurality of support seats 32 are fixedly arranged at equal intervals near both sides of the support 31. The top ends of the plurality of support seats 32 on the same side are fixed to the bottom surface of an L-shaped plate 33. The two L-shaped plates 33 are arranged oppositely. A plurality of rollers 34 are also installed at equal intervals on the support 31 near the L-shaped plate 33. With the cooperation of the L-shaped plate 33 and the rollers 34, the movement operation of the seedling floating tray or the seedling tray on the tobacco leaf shearing support frame 3 is completed.

[0023] In order to extend the usage range of the leaf pruning support frame 3 and improve the leaf pruning efficiency, auxiliary support frames 4 are rotatably connected to both ends of the leaf pruning support frame 3 through hinge members. The auxiliary support frame 4 includes an auxiliary frame 41, an auxiliary seat 42, an L-shaped auxiliary plate 43, and an auxiliary wheel 44. Pin sleeves 35 are fixed on both sides of the adjacent ends of the auxiliary frame 41 and the support frame 31. A pin 7 is sleeved between the two pin sleeves 35 on the same side. Through the pin 7, the auxiliary support frame 4 and the leaf pruning support frame 3 can be at the same height, which is convenient for cooperation.

[0024] A plurality of auxiliary seats 42 are fixedly arranged at equal intervals near both sides of the auxiliary frame 41. The tops of the plurality of auxiliary seats 42 on the same side are fixed to the bottom surface of an L-shaped auxiliary plate 43. The two L-shaped auxiliary plates 43 are arranged oppositely. Auxiliary wheels 44 are also installed at equal intervals on the auxiliary frame 41 near the L-shaped auxiliary plate 43.

[0026] In summary, during use, first adjust the height of the leaf pruning support frame 3 through the lifting adjustment mechanism 2, so as to complete the height adjustment of the smoke seedlings to be pruned by adjusting the height of the leaf pruning support frame 3. Then use the pin 7 to make the auxiliary support frame 4 and the leaf pruning support frame 3 at the same height. Then place the seedling floating tray or the seedling tray on one side of the auxiliary support frame 4. The sequentially placed seedling floating trays or seedling trays generate an inward pushing force on the auxiliary support frame 4, so that the smoke seedlings on the seedling floating tray or the seedling tray pass under the leaf pruning blade 52 in sequence. Under the action of the leaf pruning motor, the pruning of the smoke seedlings can be completed, which is convenient and practical.
