The lifting device includes two lifting chains symmetrically arranged on both sides of the inner front end of the sub-barn and a lifting drive device for driving the lifting chains. Symmetrically arranged lifting hooks are fixed to each of the two lifting chains. The lifting drive device drives the lifting hooks up and down via the lifting chains. The lifting hooks are used to place tobacco rods. The tobacco rod loading and unloading mechanism is located at the front end of the sub-barn. The tobacco rod loading and unloading mechanism includes a horizontal support plate with... The system includes a material plate parallel to a support plate, a pushing device mounted on the support plate for horizontally moving the material plate along the front-back direction of the sub-curing chamber, two symmetrically arranged horizontal tobacco rod hooks fixed on the side of the material plate away from the front end of the sub-curing chamber at both ends, and two symmetrically arranged horizontal sliding rods fixed on the side of the material plate near the front end of the sub-curing chamber at both ends. A sliding bearing cooperating with the sliding rods is fixed on the support plate, a slide rail is vertically fixed on the upper surface of the support plate, and a rack perpendicular to the support plate is fixed on the slide rail. The system also includes a fixed tube fixed to the sub-curing chamber, with open ends at the upper and lower ends.

[0016] The beneficial effects of this utility model are as follows: During operation, the tobacco rod loading and unloading mechanism moves to the end of the first-layer conveyor chain. The two ends of the tobacco rod, with the tobacco leaves tied to it, are positioned on two lifting hooks. The lifting chain drives the tobacco rod upwards until it reaches a position above the end of the first-layer conveyor chain. The tobacco rod hook is located below the lifting hook. The pushing device pushes out the first section of the tobacco rod hook, and the lifting chain drives the lifting hook to descend and reset. During the descent, the tobacco rod is placed on the tobacco rod hook. The pushing device then pushes out the second section of the tobacco rod hook. After descent, the tobacco rod is placed on the conveyor chain. Finally, the tobacco rod hook retracts and resets. The conveyor chain, driven by the conveyor drive device, moves backward one working position. This process is repeated. The process continues until the first layer of the conveyor chain is full, then it moves to the second, third, and so on, until the first layer is completely filled with tobacco stalks tied with tobacco leaves. When the tobacco leaves are cured and the stalks are to be removed, the process is reversed: the stalk hook extends and then rises to connect the first stalk on the first layer of the conveyor chain to the hook, then retracts to be directly above the lifting hook, and then descends to hand the stalk over to the lifting hook. The lifting hook descends to send the stalk to the bottom, and the first layer of the conveyor chain moves the remaining stalks forward one position. This process is repeated until all the stalks are removed. This invention can automatically load and unload tobacco stalks at an adjustable speed, meeting the tobacco company's requirements for the number of stalks to be cured, and is highly efficient.

[0038] In operation, the tobacco rod loading and unloading mechanism moves to the end of the first-layer conveyor chain 21. The two ends of the tobacco rod with the tobacco leaves tied to it are positioned on the two lifting hooks 32. The lifting chain 31 drives the tobacco rod upwards, reaching a position above the end of the first-layer conveyor chain 21. The tobacco rod hook 43 is located below the lifting hook 32. The pushing device pushes out the first section of the tobacco rod hook 43, and the lifting chain 31 drives the lifting hook 32 to descend and reset. During the descent of the lifting hook 32, the tobacco rod is placed on the tobacco rod hook 43. The pushing device then pushes out the second section of the tobacco rod hook 43. After descent, the tobacco rod is placed on the conveyor chain 21. Finally, the tobacco rod hook 43 retracts and resets. The conveyor chain 21 moves backward one working position under the drive of the conveyor drive device. This process is repeated until the first layer of conveyor chain 21 is full, then it moves to the second layer, the third layer, and so on, until the first layer is completely filled with tobacco stalks tied with tobacco leaves. When the tobacco leaves are roasted and the stalks are to be removed, the process is reversed: the stalk hook 43 extends and then rises to connect the foremost stalk on the first layer of conveyor chain 21 to the hook 43, then retracts to be directly above the lifting hook 32, and then descends to hand the stalk over to the lifting hook 32. The lifting hook 32 then descends to bring the stalk to the bottom, and the first layer of conveyor chain 21 moves the remaining stalks forward one position. This process is repeated until all the stalks are removed. This invention can automatically load and unload stalks at an adjustable speed, meeting the tobacco company's requirements for the number of stalks to be roasted, and is highly efficient.
