Description

Technical Field

[0001] This utility model relates to the technical field of tobacco processing equipment, and in particular to an integrated upper and lower curing device for tobacco curing in a dense curing barn. Background Technology

[0002] After the tobacco leaves are harvested, they need to be woven and hung on tobacco poles. Then, the staff will manually hang the tobacco poles on the tobacco hanging beams in the curing barn for curing. In order to improve the space utilization in the curing barn, multiple layers of tobacco poles are often hung in the curing barn.

[0003] However, because multiple layers of smoke poles need to be manually hung, and the middle and top layers of the smoke-hanging beams are high off the ground, workers cannot stand on the ground to hang the smoke poles directly on the middle and top layers of the smoke-hanging beams.

[0004] Therefore, workers need to use ladders or lifting devices to hang tobacco leaves off the ground, which poses a certain threat to their personal safety. In addition, because the tobacco leaves on a single tobacco pole are quite heavy, an additional worker is usually needed at the middle level of the tobacco hanging beam to pass the tobacco pole to the top level. Utility Model Content

[0005] In view of the above problems, this utility model provides an integrated upper and lower racking device for tobacco curing in a dense curing barn, the purpose of which is to improve the efficiency of tobacco hanging, avoid working at height, and ensure the personal safety of workers.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A device for raising and lowering tobacco in a dense tobacco curing barn is provided, comprising: several columns vertically installed inside the curing barn; a first tobacco hanging beam and a second tobacco hanging beam, spaced at a fixed height and slidably mounted on the columns; several layers of third tobacco hanging beams suspended below the second tobacco hanging beams via flexible connecting components; and a driving component for driving the first and second tobacco hanging beams to move up and down synchronously in the vertical direction.

[0007] Furthermore, the device also includes: a first supporting component, which is slidably sleeved on the column, one side of the first supporting component is for placing a first or second smoke-hanging beam, and the other side of the first supporting component is provided with a roller that can roll and contact the column; a second supporting component, which is slidably sleeved on the column, one side of the second supporting component is for placing a third smoke-hanging beam, and the other side of the second supporting component is also provided with a roller that can roll and contact the column.

[0008] Furthermore, the device also includes: a lead screw rotatably mounted in each column; a slide groove formed in the column; a nut slidably disposed in the slide groove and mounted on the lead screw via threaded transmission, with nuts fixedly mounted on both the first and second bearing components; and a slider slidably disposed in the slide groove and sleeved on the lead screw, with a slider fixedly mounted on each second bearing component.

[0009] Furthermore, the driving component is a servo motor, which is connected to the lead screw via a coupling.

[0010] Furthermore, the device also includes: a lug, disposed on the first and second load-bearing components, for mounting the flexible connecting component.

[0011] Furthermore, the device also includes a first reinforcing rib and a second reinforcing rib, which are fixedly installed at the upper and lower ends of the column, respectively, to form a frame structure.

[0012] Furthermore, the flexible connecting component is one or more of a chain, wire rope, or nylon rope.

[0013] The beneficial effects of this utility model are as follows: By setting up columns to support the weight of the tobacco leaves, the walls of the curing barn do not need to bear the weight of the tobacco leaves, thus avoiding damage to the curing barn, increasing its service life, and reducing the investment and cost of reinforcing the curing barn; workers only need to stand on the ground to hang the woven tobacco poles or tobacco clips, eliminating the need for workers to climb to heights, effectively ensuring the personal safety of workers; reducing the number of workers required for hanging tobacco on the curing barn, reducing labor demand, and improving the efficiency of hanging tobacco, thus achieving cost reduction and efficiency improvement in the process of hanging tobacco on and off the curing barn.

Detailed Implementation

[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] Example 1 Reference Figure 1 and Figure 2 As shown, this embodiment provides a intensive tobacco curing barn overall lifting and lowering device, including: several columns 1, vertically installed inside the curing barn; a first tobacco hanging beam 21 and a second tobacco hanging beam 22, spaced at a fixed height and slidably mounted on the columns 1; several layers of third tobacco hanging beams 23, suspended below the second tobacco hanging beams 22 by flexible connecting components 5; and a driving component 3, used to drive the first tobacco hanging beams 21 and the second tobacco hanging beams 22 to move up and down synchronously in the vertical direction.

[0020] In practical use, during operation, the drive unit 3 is activated, causing the first tobacco beam 21 and the second tobacco beam 22 to descend synchronously until the first tobacco beam 21 reaches a height suitable for the worker to stand and operate. Then, the worker places the woven tobacco poles or tobacco clips on the first tobacco beam 21, hangs the tobacco leaves, and then activates the drive unit 3 again to raise the first tobacco beam 21 until the second tobacco beam 22 reaches a height suitable for the worker to stand and operate. This cycle is repeated to complete the tobacco leaf loading operation. It is understandable that the tobacco leaf unloading operation is the reverse of the loading operation.

[0021] In this utility model, the weight of the tobacco leaves is supported by the upright column 1, eliminating the need for the walls of the curing barn to bear the weight of the tobacco leaves, thus avoiding damage to the curing barn, increasing the service life of the curing barn, and reducing the investment and cost of reinforcing the curing barn. In addition, compared with manual tobacco hanging, in this invention, workers only need to stand on the ground to hang the woven tobacco poles or tobacco clips, eliminating the need for workers to climb to heights, effectively ensuring the personal safety of workers; reducing the number of workers required for tobacco hanging on the kang (heated brick bed), reducing labor demand, and improving the efficiency of tobacco hanging, thus achieving cost reduction and efficiency improvement in tobacco curing.

[0022] Specifically, the device further includes: a first supporting component 41, which is slidably sleeved on the column 1, with one side of the first supporting component 41 for placing the first smoke hanging beam 21 or the second smoke hanging beam 22, and the other side of the first supporting component 41 is provided with a roller 44 that can be rolled and can roll in contact with the column 1; a second supporting component 42, which is slidably sleeved on the column 1, with one side of the second supporting component 42 for placing the third smoke hanging beam 23, and the other side of the second supporting component 42 is also provided with a roller 44 that can roll in contact with the column 1.

[0023] In this utility model, by providing the first bearing component 41 and the second bearing component 42, effective support can be provided for the first smoke hanging beam 21, the second smoke hanging beam 22 and the third smoke hanging beam 23 respectively; in addition, by providing the roller 44, the wear of the first bearing component 41 and the second bearing component 42 can be reduced and the service life extended.

[0024] It is worth mentioning that the first smoke beam 21 and the second smoke beam 22 can be fixedly installed on the first load-bearing component 41 by bolts or by welding; similarly, the installation of the third smoke beam 23 can be obtained.

[0025] Reference Figure 3 and Figure 4 As shown, the device also includes: a lead screw 61, rotatably mounted in each column 1; a slide groove 62, formed in the column 1; a nut 63, slidably disposed in the slide groove 62, and mounted on the lead screw 61 via threaded transmission; nuts 63 are fixedly mounted on both the first bearing component 41 and the second bearing component 42; and a slider 64, slidably disposed in the slide groove 62 and sleeved on the lead screw 61; slider 64 is fixedly mounted on each second bearing component 42.

[0026] It is worth mentioning that the two nuts 63, which are installed on the first bearing component 41 and the second bearing component 42 respectively, are installed on the lead screw at a fixed distance. By driving the lead screw 61 to rotate through the drive component 3, the nuts 63 can slide in the slide groove 62, and drive the first cigarette hanging beam 21 and the second cigarette hanging beam 22 to move up and down synchronously.

[0027] In this embodiment, the third smoke-hanging beam 23 of the two layers is suspended below the second load-bearing component 42 by a flexible connecting component 5.

[0028] It is understandable that the nut 63 is a commercially available trapezoidal nut; the lead screw 61 can be rotatably mounted on the column 1 via a bearing.

[0029] In this invention, the lead screw 61 and nut 63 work together to drive the tobacco leaves. The lead screw drive itself has a self-locking capability, which can prevent tobacco leaves from falling or slipping in a high-temperature and high-humidity working environment. In addition, the lifting of each layer is based on the engagement or sliding of the lead screw as the axis. The hanging tobacco rod will not swing during the lifting process, preventing shaking and thus greatly avoiding the loss of tobacco leaves.

[0030] Specifically, the drive component 3 is a servo motor, which is connected to the lead screw 61 via a coupling.

[0031] In this embodiment, each column 1 is equipped with a corresponding servo motor installed on each lead screw 61.

[0032] It is understandable that existing transmission devices such as worm gears, gears, and lead screw 61 lifts can be used to link several lead screws 61 together, thereby reducing the number of servo motors.

[0033] In this embodiment, the servo motor is located at the top of the column 1; it is understood that the servo motor can also be placed in the middle, bottom, or other positions of the column 1. Specifically, the device also includes: a hanging ear 43, which is disposed on the first bearing member 41 and the second bearing member 42, for the flexible connecting member 5 to be installed, and the flexible connecting member 5 is hung in the through hole of the hanging ear 43.

[0034] Preferably, the device further includes a first reinforcing rib 11 and a second reinforcing rib 12, which are respectively fixedly installed at the upper and lower ends of the column 1 to form a frame structure.

[0035] In this embodiment, six columns 1 are provided, and six lead screws 61 are provided corresponding to the six columns 1. The six lead screws 61 are divided into three groups, and three groups of first smoke-hanging beams 21, second smoke-hanging beams 22 and third smoke-hanging beams 23 are installed corresponding to the three groups of lead screws 61.

[0036] It is understandable that the number and installation position of the columns 1 can be flexibly increased or decreased depending on the size of the drying room.

[0037] It is worth mentioning that, for the sake of stable installation of column 1, the number and installation connection position of the first reinforcing rib 11 and the second reinforcing rib 12 can also be flexibly adjusted.

[0038] It is understandable that the drive component 3 could also be a hand-cranked reducer, allowing for manual lifting and lowering.

[0039] Preferably, the flexible connecting component 50 can be one or more of a chain, wire rope, or nylon rope. Example 2 In this embodiment, fresh tobacco leaves are strung together using tobacco sticks or tobacco clips and then placed in layers on the first tobacco beam 21, the second tobacco beam 22, and the third tobacco beam 23 in the curing barn for curing. When strung together, the tobacco sticks are about 1.5 meters long, and each stick of tobacco leaves weighs 8-10 kg; if tobacco clips are used, the clips are about 1.4 meters long, and each clip holds 15-20 kg of tobacco leaves.

[0040] In this embodiment, the dense curing barn is divided into three or four layers, with a width of 2.7 meters and a length of 8 meters. The maximum tobacco hanging height in the three-layer curing barn is 3 meters, and the maximum tobacco hanging height in the four-layer curing barn is 3.5 meters. Each layer has 100 tobacco sticks / clamps, and the maximum wet weight after being fully hung with tobacco leaves can reach 10 tons.

[0041] By using this utility model, workers only need to stand on the ground to hang tobacco leaves, eliminating the need for strong laborers to climb to heights. This reduces labor demand, increases tobacco leaf hanging efficiency, and avoids the risks of working at heights, achieving cost reduction and efficiency improvement in tobacco curing and increasing safety.
