[0002] Traditional drying rooms feature a fixed, multi-layered structure. When items are brought into the drying room for drying, several common methods are commonly used: First, push the items into the drying room using a cart. Second, manually place the items on fixed shelves built into the drying room. Third, arrange the items and manually transfer them to the multi-layered, fixed drying racks built into the drying room. These methods all have significant shortcomings, including limited drying room space, which precludes streamlined operations and leads to low efficiency. There's no room to adjust items on the top layer, and manually placed items have inconsistent spacing, resulting in inconsistent drying results.

[0033] An intermediate drying rod rack 15 and a bottom drying rod rack 16 are provided below the top drying rod rack 14. The lower end of the bottom drying rod rack 16 is connected to a support rod 17, which is connected to the lower end of the drying room body 1 and is located at the side wall of the roller column 13. The outside of the intermediate drying rod rack 15 is connected to an intermediate C-shaped frame assembly 18, which is slidably connected to the roller column 13. The lower end of the lifting ring 11 is connected to a lifting chain 19, which passes through the intermediate drying rod rack 15 and the bottom drying rod rack 16 and extends to the inside of the support rod 17. The outside of the lifting chain 19 is connected to a support block 20 for supporting and lifting the intermediate drying rod rack 15;

[0034] Both ends of the top drying rod rack 14 , the middle drying rod rack 15 and the bottom drying rod rack 16 are connected to guide wheels 21 , and the outer portion of the guide wheel 21 is in rolling contact with a guide groove 22 , which is installed on the inner wall of the drying room body 1 .

[0038] Specifically, the upper C-type frame assembly 12 and the middle C-type frame assembly 18 both include a C-type plate 1801 and a roller 1802. The roller 1802 is located inside the roller column 13 and is rollingly connected, which facilitates maintaining stability during the lifting process of the top drying rod rack 14 and the middle drying rod rack 15, ensuring that the lifting and lowering are carried out in the same vertical direction.

[0039] A controller 23 for controlling power transmission is installed on the outer side wall of the drying room body 1 to regulate the operation of the entire device.

[0040] Working principle: Transmission of the first-stage reduction mechanism 5:

[0041] After the motor 502 is started, the power is transmitted to the reducer 504 through the coupling 503. The reducer 504 reduces the speed of the motor 502 and increases the torque. The reduced power is transmitted to the three secondary reduction mechanisms 4 through the transmission shaft 6.

[0042] In the two-stage reduction mechanism 4, the worm 403 and the worm wheel 404 are meshed and driven to further reduce the rotation speed and increase the torque, ultimately driving the retractable shaft 7 to rotate;

[0043] Retraction and extension of the hoisting mechanism 8:

[0044] When the retractable shaft 7 rotates, it drives the hoisting disc 803 in the hoisting mechanism 8 to rotate. The hoisting wire rope 804 wound around the hoisting disc 803 is driven by the pulley 806 to drive the screw rod 9 to move up and down.

[0045] The screw rod 9 is used in conjunction with the nut 10 and the ring 11 to connect the upper C-frame assembly 12, and the top drying rod rack 14 is installed in the upper C-frame assembly 12. In this way, when the hoisting mechanism 8 is retracted and extended, the top drying rod rack 14 is raised and lowered;

[0046] Drying rod lifting and guiding:

[0047] The lifting movement of the screw rod 9 drives the upper C-frame assembly 12 and the middle C-frame assembly 18 to slide on the roller column 13;

[0048] The top drying rod rack 14 connected to the interior of the upper C-shaped frame assembly 12 and the middle drying rod rack 15 connected to the exterior of the middle C-shaped frame assembly 18 rise and fall with the rise and fall of the upper C-shaped frame assembly 12 and the middle C-shaped frame assembly 18 respectively;

[0049] The bottom drying rack 16 is connected to the lower end of the drying room body 1 through the support rod 17 to maintain a fixed position;

[0050] During the lifting process, the guide wheel 21 rolls in the guide groove 22 to ensure the stability and accuracy of the lifting of the drying rack;

[0051] The support block 20 supports the lifting chain 19:

[0052] The lifting chain 19 passes through the middle drying rack 15 and the bottom drying rack 16 and extends to the inside of the support rod 17. The outside of the lifting chain 19 is connected to a support block 20 for supporting the middle drying rack 15 during the lifting process and driving it to move up and down;

[0053] The position of the support block 20 can determine the height position of the middle drying rack 15 of each layer, which is used to adjust the layer height. The device is preferably set up as a three-layer drying rack structure. If the number of drying rack layers increases, the position of each layer of drying rack can be positioned and supported by installing the support block 20 on the lifting chain 19;

[0054] Overall workflow:

[0055] When the items that need to be dried (such as tobacco leaves, food, medicinal materials, fruits, etc.) are loaded into the drying room body 1, the top drying rack 14 is lowered to a height suitable for manual operation. The operator works on the ground. After the top drying rack 14 is filled manually, this layer of drying rack is electrically raised, and the operator then fills the middle drying rack 15. After it is filled, the second layer of drying rack and the raised first layer of drying rack are raised at the same time. If the number of layers of the middle drying rack 15 increases, the items to be dried are placed in turn, and so on. Finally, the operator fills the bottom drying rack 16;

[0056] Its purpose is to reduce the high intensity of manual work, reduce labor costs, and improve work efficiency. In this way, when operating manually, there is no need to lift the items to be dried very high, and even no need to use tools such as ladders to fill the entire drying room with items. Manual ground work is realized, avoiding the safety problems caused by high-altitude work. Ground work can also effectively adjust the gaps between the items to be dried, which can ensure the purpose of improving the space utilization of the drying room, that is, more items and heavier weights can be dried.

[0057] In summary, the present device realizes the stable, accurate and efficient lifting function of the drying room lifting device through the coordinated action of the motor 502 driving the deceleration device, the retraction and extension of the hoisting mechanism 8 and the guide mechanism.
