[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] refer to Figure 1-2 A semi-automatic tobacco hanging and curing device includes a curing barn 1, a first tobacco hanging layer 2, a second tobacco hanging layer 3, a third tobacco hanging layer 4, and a lifting assembly 5. The first tobacco hanging layer 2 is located at the bottom of the curing barn 1 and is used for hanging tobacco at the bottom of the curing barn 1. The second tobacco hanging layer 3 can be arranged parallel above the first tobacco hanging layer 2 and can be raised and lowered inside the curing barn 1 for hanging tobacco in the middle of the curing barn 1. The third tobacco hanging layer 4 can be arranged parallel above the second tobacco hanging layer 3 for hanging tobacco at the top of the curing barn 1. The third tobacco hanging layer 4 is connected to the second tobacco hanging layer 3. The lifting assembly 5 is located at the top of the curing barn 1 and is connected to the third tobacco hanging layer 4. The lifting assembly 5 can drive the third tobacco hanging layer 4 and the second tobacco hanging layer 3 to rise and fall, thereby realizing the hanging of tobacco at different heights inside the curing barn 1, realizing semi-automatic tobacco hanging, avoiding manual climbing to hang tobacco, reducing labor intensity, improving tobacco hanging efficiency, and adjusting the hanging height according to actual conditions to meet different tobacco curing needs.

[0028] In some embodiments, the lifting assembly 5 includes a drive unit 51, a lifting frame 52, a fixed frame 53, a pulley 54, and a wire rope 55. The drive unit 51 is located at the top of the curing barn 1 and can be an electric hoist with a controller. The drive unit 51 is controlled by a transformer. The lifting frame 52 is connected to the drive unit 51 and to the third tobacco hanging layer 4. The fixed frame 53 is located at the top of the curing barn 1, and the pulley 54 is located on the fixed frame 53. One end of the wire rope 55 is connected to the drive unit 51, and the other end is connected to the lifting frame 52, and slides with the pulley 54. When the drive unit 51 is activated, it drives the lifting frame 52 to rise and fall through the wire rope 55 and pulley 54 system. Since the lifting frame 52 is connected to the third tobacco hanging layer 4, and the third tobacco hanging layer 4 is connected to the second tobacco hanging layer 3, it drives the entire second tobacco hanging layer 3 and the third tobacco hanging layer 4 to rise and fall, thereby achieving different tobacco hanging heights within the curing barn 1.

[0029] In some embodiments, the first tobacco hanging layer 2 may include three first tobacco hanging beams 21, which are respectively disposed on the two side walls and the middle of the curing barn 1. Adjacent first tobacco hanging beams 21 can hang tobacco. The second tobacco hanging layer 3 may include three second tobacco hanging beams 31, each of which is disposed parallel to and directly above the corresponding first tobacco hanging beam 21 (the central axis of the second tobacco hanging beam 31 and the central axis of the first tobacco hanging beam 21 are located on the same vertical plane). Adjacent second tobacco hanging beams 31 can hang tobacco. The third tobacco hanging layer 4 includes three third tobacco hanging beams. 41. Each third tobacco hanging beam 41 is parallel to the second tobacco hanging beam 31 directly above it (the central axis of the third tobacco hanging beam 41 and the central axis of the second tobacco hanging beam 31 are on the same vertical plane). Two adjacent third tobacco hanging beams 41 can hang tobacco. The third tobacco hanging beam 41 and the second tobacco hanging beam 31 can be connected by a chain. Through the flexible connection of the chain, the third tobacco hanging beam 41 can be lowered to the bottom of the curing barn 1 under the drive of the lifting component 5, which facilitates the hanging of tobacco in the third tobacco hanging layer 4. At the same time, it can drive the second tobacco hanging beam 31 to rise and fall, realizing the rise and fall of the second tobacco hanging layer 3.

[0030] In some embodiments, the curing barn 1 is also provided with guide columns 6, and both ends of the curing barn 1 are provided with guide columns 6. The guide columns 6 pass through the second tobacco beam 31 and the third tobacco beam 41. The guide columns 6 limit the movement of the second tobacco beam 31 and the third tobacco beam 41 during the lifting and lowering process, reduce the positional deviation of the second tobacco beam 31 and the third tobacco beam 41 during the lifting and lowering process, and thus improve the stability of the lifting and lowering of the second tobacco layer 3 and the third tobacco layer 4.

[0031] In some embodiments, a limit switch is also included. The limit switch is disposed on the lifting frame 52 and electrically connected to the drive component 51. The output of the drive component 51 can be controlled by the limit switch, thereby controlling the lifting stroke of the device. This can achieve accurate control of the lifting height of the second smoke layer 3 and the third smoke layer 4, while preventing damage caused by excessive lifting. The limit switch is prior art and will not be described in detail here.

[0032] In some embodiments, a limiting component 7 is also included. The limiting component 7 includes a limiting rod 71 and an elastic support block 72. The limiting rod 71 is located directly above the first smoke hanging beam 21 and the second smoke hanging beam 31. The elastic support block 72 is located on the top of the limiting rod 71. The elastic support block 72 can be a rubber block. The top of the elastic support block 72 can be provided with a limiting groove that matches the shape of the third smoke hanging beam 41 and the second smoke hanging beam 31. This can provide buffering and limiting during the lifting process, avoiding direct collision between the first smoke hanging beam 21 and the second smoke hanging beam 31, and between the third smoke hanging beam 41 and the second smoke hanging beam 31, thereby protecting the smoke hanging layer from damage.

[0033] The specific working principle is as follows:

[0034] In operation, the lifting assembly 5 is activated by the drive unit 51. When curing is required, the drive unit 51 lowers the third tobacco layer 4 to a convenient operating height (e.g., 1.65 meters). At this point, the limit switch is activated, sending a signal to the drive unit 51, which then stops operating. After the operator places the tobacco leaves onto the third tobacco layer 4, the drive unit 51 is activated again, raising the third tobacco layer 4. When the third tobacco layer 4 reaches a certain height (e.g., 2.2 meters), the drive unit 51 is manually stopped, and the operator places the tobacco leaves onto the second tobacco layer 3. Then, the drive unit 51 is activated again, and the third tobacco layer 4 continues to rise to the maximum working height (e.g., 2.95 meters). At this point, the limit switch is activated again, sending a signal to the drive unit 51, which then stops operating. During this process, the second tobacco layer 3 rises along with the third tobacco layer 4. The operator then places the tobacco leaves onto the first tobacco layer 2, completing the tobacco hanging work in the curing barn 1. The curing barn 1 is then closed, and the curing process begins. When baking the bottom layer of the oven, simply reverse the process to bake the bottom layer.
