Description

Technical Field

[0001] This utility model relates to the technical field of tobacco leaf hanging equipment, and in particular to a lifting tobacco rack. Background Technology

[0002] The curing of tobacco leaves is a delicate and complex process and one of the most critical links in flue-cured tobacco production. The use of tobacco racks plays an important role in the curing process, as they can significantly increase the amount of tobacco that can be loaded into the curing barn, thereby improving the curing efficiency of the barn.

[0003] During the operation, the tobacco leaves to be cured need to be hung in rows on the tobacco racks. Due to the high height inside the curing barn, workers usually need to use climbing equipment such as ladders to hang the tobacco leaves. The hanging operation poses safety hazards, requires multiple climbs, is labor-intensive, and has low hanging efficiency, which needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting tobacco rack and a tobacco curing barn, which can lift the tobacco rack to facilitate the operator in hanging the tobacco leaves.

[0005] The technical implementation scheme of this utility model is as follows:

[0006] A lifting cigarette rack includes a fixed frame, a lifting mechanism, a traction mechanism, and a drive mechanism. The fixed frame has a rectangular frame structure, and the lifting mechanism is located on the upper part of the fixed frame. The lifting mechanism is connected to the drive mechanism through the traction mechanism to form a transmission structure. The lifting mechanism includes a first lifting bracket, a second lifting bracket, a third lifting bracket, and a connecting rope. Both ends of the first, second, and third lifting brackets are movably connected to guide strips on the fixed frame through sliding grooves. The first and second lifting brackets are connected by a connecting rope, and the second and third lifting brackets are connected by a connecting rope to form a support frame structure. The traction mechanism includes a first traction belt, a second traction belt, and a first fixed pulley. One end of the first traction belt is connected to the first lifting bracket, and the other end of the first traction belt is connected to the drive mechanism through the first fixed pulley.

[0007] Optionally, the two ends of the connecting rope are respectively connected to the connecting ears on the lifting bracket, the connecting ears are arranged at intervals along the direction of the lifting bracket, and the connecting ears on the first lifting bracket and the second lifting bracket are symmetrically arranged vertically.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0025] like Figures 1-8 As shown, a lifting cigarette rack includes a fixed frame 1, a lifting mechanism 2, a traction mechanism 3, and a drive mechanism 4. The fixed frame 1 has a rectangular frame structure, and the lifting mechanism 2 is provided on the upper part of the fixed frame 1. The lifting mechanism 2 is connected to the drive mechanism 4 through the traction mechanism 3 to form a transmission structure. The lifting mechanism 2 includes a first lifting bracket 201, a second lifting bracket 202, a third lifting bracket 203, and a connecting rope 204. Both ends of the first lifting bracket 201, the second lifting bracket 202, and the third lifting bracket 203 are connected to the fixed frame through sliding grooves. The guide bar 5 on 1 is movably connected. The first lifting bracket 201 and the second lifting bracket 202 are connected by a connecting rope 204. The second lifting bracket 202 and the third lifting bracket 203 are connected by a connecting rope 204 to form a support frame structure. The traction mechanism 3 includes a first traction belt 301, a second traction belt 304 and a first fixed pulley 302. One end of the first traction belt 301 is connected to the first lifting bracket 201, and the other end of the first traction belt 301 is connected to the drive mechanism 4 through the first fixed pulley 302.

[0026] It should be noted that when drying tobacco leaves, they are usually hung on a tobacco rack before being dried by drying equipment. However, existing tobacco racks are quite high, requiring operators to climb ladders to hang them. This not only makes it inconvenient for operators to retrieve the leaves but also poses safety hazards. Therefore, we have designed a lifting tobacco rack that can raise the lifting mechanism 2 via the traction mechanism 3, allowing operators to hang the tobacco leaves at a lower position, thereby improving the efficiency of the hanging process.

[0027] It should be further explained that the lifting mechanism 2 is installed inside the fixed frame 1 and is composed of a first lifting bracket 201, a second lifting bracket 202, and a third lifting bracket 203. Each of these three lifting brackets has sliding grooves on both sides, which are movably connected to the guide strips 5 on the fixed frame 1. Thus, under the traction of the traction mechanism 3, smooth lifting and lowering can be achieved. The first lifting bracket 201, the second lifting bracket 202, and the third lifting bracket 203 are interconnected by connecting ropes 204, forming a stable frame structure, which greatly facilitates the operator in hanging tobacco leaves.

[0028] like Figures 1-4 As shown, the two ends of the connecting rope 204 are connected to the connecting ears 205 on the lifting bracket respectively. The connecting ears 205 are arranged at intervals along the direction of the lifting bracket, and the connecting ears 205 on the first lifting bracket 201 and the second lifting bracket 202 are arranged symmetrically up and down.

[0029] It should be noted that the connecting rope 204 is a flexible rope, with both ends set on the connecting ears 205 of the lifting bracket to connect the two lifting brackets and form a bracket structure. Therefore, the operator can hang tobacco leaves on the first lifting bracket 201, the second lifting bracket 202 and the third lifting bracket 203, which is convenient for the operator to use.

[0030] like Figures 1-6 As shown, the other end of the first traction belt 301 passes through the openings on the side of the second lifting bracket 202 and the third lifting bracket 203 and is connected to the bottom of the first lifting bracket 201.

[0031] It should be noted that, in order to achieve the lifting, we use the traction mechanism 3 to pull and lift the lifting mechanism 2. In this process, the drive mechanism 4 drives the first traction belt 301 and the second traction belt 304 to lift the first lifting bracket 201, which facilitates lifting. Moreover, the lifting method using two traction belts makes the lifting process more stable and practical.

[0032] like Figures 1-8As shown, the drive mechanism 4 includes a fixed bracket 401, a gear set, a drive motor 404, a first gear 402, a second gear 405, a first sprocket 408, and a second chain 406. The fixed bracket 401 is mounted on the fixed frame 1, and the gear set is installed inside the fixed bracket 401. The gear set is connected to the drive motor 404 via a connector. The other end of the gear set is connected to a first rotating shaft. The first rotating shaft is connected to the first rotating shaft via the meshing of the first gear 402 and the second gear 405 on the second rotating shaft. The first rotating shaft is provided with a first sprocket 408, which is connected to a chain 303 on the first traction belt 301. The second rotating shaft is provided with a second sprocket 407, which is connected to another chain on the second traction belt 304. A first fixed pulley 302 is provided at each inflection point of the first traction belt 301.

[0033] It should be noted that the fixed bracket 401 is mounted on the fixed frame 1, and a gear set and a drive motor 404 are installed inside the fixed bracket 401. The drive motor 404 drives the first rotating shaft, and the first rotating shaft is equipped with a first sprocket 408. The first sprocket 408 is connected to the chain 303 on the first traction belt 301, thereby driving the first traction belt 301 and realizing the lifting mechanism 2.

[0034] It should be further explained that the first rotating shaft is connected to the second rotating shaft by meshing with the first gear 402 and the second gear 405 on the second rotating shaft. The rotation of the first rotating shaft will also rotate the second rotating shaft, thereby realizing the smooth lifting of the entire lifting mechanism 2.

[0035] like Figure 7 and Figure 8 As shown, a tobacco curing barn includes a chamber 8, and a liftable tobacco rack is installed inside the chamber 8.

[0036] It should be noted that a tobacco curing barn is equipped with an air guiding system and an exhaust system at the top, and a lifting tobacco rack is installed inside the chamber 8 to hang the tobacco leaves for drying.

[0037] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
