DETAILED DESCRIPTION

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-5 As shown, a flexible loading and unloading device for dense curing barn includes a curing barn 1. A U-shaped base 2 is fixedly connected to the inner wall of the bottom of the curing barn 1. A first tobacco rack 3 is slidably arranged inside the U-shaped base 2. Two second tobacco racks 4 are symmetrically arranged on both sides of the first tobacco rack 3. The tops of the first tobacco rack 3 and the second tobacco rack 4 are connected together by at least two connecting rods 5. The two ends of the tobacco hanging rod to be placed are respectively set on the first tobacco rack 3 and the corresponding second tobacco rack 4. A lifting component 6 for driving the first tobacco rack 3 to lift is provided on the U-shaped base 2.

[0030] The lifting assembly 6 includes two mounting plates 61 symmetrically arranged on both sides of the middle of the first cigarette rack 3. The bottom ends of the two mounting plates 61 are fixedly connected to the U-shaped base 2. The two mounting plates 61 are respectively provided with a limiting groove 63 and a movable groove 62 along their length. A rack 64 and a limiting block 65 are respectively provided on the outer walls of both sides of the first cigarette rack 3. The limiting block 65 is slidably arranged in the limiting groove 63. A gear 66 is rotatably arranged in the movable groove 62. The gear 66 is meshed with the rack 64. A motor 67 is drivenly connected to one side of the gear 66. The motor 67 is fixedly installed on the corresponding mounting plate 61.

[0031] In use, the operator presses the motor 67 descent button on the control panel (the control panel is existing technology, so it will not be described in detail in this embodiment). This starts the motor 67 to rotate forward. After the motor 67 is powered on, it starts to run, driving the gear 66 connected to it to rotate clockwise in the movable slot 62 (assuming that the forward rotation direction is the descent direction).

[0032] Since gear 66 meshes with rack 64 on the outer wall of the first cigarette rack 3, the rotation of gear 66 causes rack 64 to move downward along mounting plate 61. At the same time, limiting block 65 on the outer wall of the first cigarette rack 3 slides downward synchronously in limiting groove 63. Limiting groove 63 guides and restricts limiting block 65, so that the first cigarette rack 3 can only descend smoothly in the vertical direction, without any unstable situations such as left-right deviation, front-back swaying or rotation. At the same time, as the first cigarette rack 3 descends, the connecting rod 5 at the top drives the second cigarette racks 4 on both sides to descend synchronously, achieving a uniform descent of the entire cigarette rack structure.

[0033] During the operation of motor 67, the operator observes the height scale pre-marked on the mounting plate 61 or uses a height monitoring device installed in the drying room 1 (such as a laser rangefinder and a height sensor, which are existing technologies and will not be described in detail in this embodiment), combined with their own operating habits and height, to determine when the first smoke rack 3 and the second smoke rack 4 have descended to the appropriate height for hanging smoke. When the appropriate height is reached, the operator stops motor 67 by controlling the button to stabilize the first smoke rack 3 and the second smoke rack 4 at this height.

[0034] After the first tobacco rack 3 and the second tobacco rack 4 are stabilized, place the two ends of the prepared tobacco hanging rod (which has been evenly covered with tobacco leaves) at the corresponding positions of the first tobacco rack 3 and the second tobacco rack 4 respectively. After the tobacco is hung, start the motor 67 to reverse through the control console or control button. The motor 67 starts to rotate counterclockwise, driving the gear 66 to rotate in the opposite direction in the movable groove 62.

[0035] As gear 66 reverses, the rack 64 meshing with it begins to move upward, thereby driving the first cigarette rack 3 to rise. The limiting blocks 65 on both sides of the first cigarette rack 3 slide upward in the limiting groove 63 to ensure that the first cigarette rack 3 remains vertical and stable during the rising process. At the same time as the first cigarette rack 3 rises, the second cigarette racks 4 on both sides are driven to rise synchronously through the connecting rod 5.

[0036] According to the baking process requirements and internal space layout of the baking room 1, the target heights of the first smoke rack 3 and the second smoke rack 4 are predetermined. The operator monitors the rising process of the first smoke rack 3 and the second smoke rack 4 through the control console. When the first smoke rack 3 and the second smoke rack 4 rise to the predetermined baking height, the motor 67 is stopped, so that the first smoke rack 3 and the second smoke rack 4 stay at this position and wait for the subsequent baking process to begin.

[0037] This design allows for flexible adjustment of the cigarette rack height based on the operator's height and operating habits, making the cigarette hanging operation more comfortable and convenient, reducing operator fatigue caused by prolonged periods of raising their arms or bending over, and improving work efficiency.

[0038] Secondly, the cooperation between the limiting groove 63 and the limiting block 65, as well as the reasonable structural design of the lifting component 6, ensures the stability of the tobacco rack during the lifting process. Thus, the tobacco rack will not fall or be damaged by collision due to shaking during the lifting process, ensuring the quality and integrity of the tobacco.

[0039] Furthermore, it ensures that the tobacco leaves are heated and ventilated evenly, adapting to the different needs of various tobacco varieties for hanging space and baking height, thus improving applicability and finished product quality.

[0040] The first cigarette rack 3 includes a T-shaped support frame 31, and multiple first placement plates 32 are symmetrically arranged on both sides of the vertical part of the T-shaped support frame 31.

[0041] The same first fixing rod 33 is fixedly sleeved inside multiple first placement plates 32 on the same side, and the top of the first fixing rod 33 is fixedly connected to the bottom of the top of the T-shaped support frame 31.

[0042] The cross-section of the first placement plate 32 is inverted T-shaped.

[0043] This design ensures that, firstly, the T-shaped support frame 31, the first placement plate 32, and the first fixing rod 33 are interconnected to form a stable frame system, which can evenly distribute the weight of the tobacco hanging rod and tobacco leaves, prevent structural deformation and damage, ensure the stability and reliability of the tobacco rack, and facilitate the tobacco curing operation.

[0044] Secondly, the first placement plate 32 with an inverted T-shaped cross-section can accurately position the tobacco hanging rod, preventing it from slipping and shifting, making it easy for operators to place it efficiently and accurately, so that the tobacco leaves are distributed neatly and are conducive to uniform heating and ventilation in the future.

[0045] Furthermore, the symmetrically distributed first placement plates 32 form air circulation channels after the tobacco leaves are placed, ensuring smooth flow of hot air, allowing the tobacco leaves to be heated evenly, and improving the quality of flue-cured tobacco.

[0046] Finally, the frame structure and sturdy connection make the cigarette rack resistant to external impacts, durable, reduce the frequency of maintenance and replacement, lower costs, and its simple structure makes it easy to locate problems and maintain and repair.

[0047] The second cigarette rack 4 includes a support plate 41, and two second fixing rods 42 are fixedly connected to the top and lower part of the support plate 41.

[0048] Multiple second placement plates 43 are provided between the two second fixing rods 42, and the number and position of the second placement plates 43 correspond one-to-one with those of the first placement plates 32.

[0049] The cross-section of the second placement plate 43 is L-shaped.

[0050] With this design, firstly, the support plate 41 provides a load-bearing foundation for the component, and the two second fixing rods 42 form a force-bearing frame to ensure the stability of the cigarette rack and prevent it from shaking or collapsing; and the two, together with the second placement plate 43, enhance the overall rigidity, so that the structure can maintain its integrity in the face of external interference, ensuring stability and durability.

[0051] Secondly, the L-shaped cross-section of the second placement plate 43 facilitates placement and operation, prevents slippage, and improves the efficiency and neatness of tobacco loading; its correspondence with the first placement plate 32 can make reasonable use of space, which is conducive to placing tobacco leaves in a regular manner and increasing the amount of tobacco to be cured.

[0052] Furthermore, the gap between the second placement plates 43 forms a hot air circulation channel, ensuring that the tobacco leaves are heated evenly, and its layout corresponds to the first tobacco rack 3, making the ventilation system of the tobacco rack more coordinated and unified, and improving the tobacco curing effect.

[0053] Finally, the structure is simple and durable, reducing vulnerable points, lowering the probability of component damage and failure, and saving costs; when problems occur, it is easy to quickly troubleshoot and perform targeted repairs, reducing the impact on tobacco curing operations.

[0054] A door 7 is rotatably connected to one of the outer walls of the baking room 1. A handle 8 is fixedly installed on the outside of the door 7, and a transparent window 9 is also embedded in the door 7.

[0055] This design, firstly, allows operators to easily, accurately, and effortlessly control the opening and closing of the door 7 through the setting of the handle 8, facilitating entry and exit from the curing barn 1 for operations such as loading, inspecting, and retrieving tobacco.

[0056] Secondly, the transparent window 9 allows operators to see the state of tobacco curing, temperature, humidity, and other conditions inside the curing barn 1 without opening the door 7, making it easier to adjust relevant conditions in a timely manner to ensure the quality of the cured tobacco.

[0057] Furthermore, the use of the transparent window 9 for observation can reduce the frequency of door opening, avoid excessive fluctuations in parameters such as temperature, humidity, and heat, maintain a stable roasting environment, reduce safety hazards, and improve the efficiency and effect of tobacco roasting.

[0058] Finally, the transparent window 9 can improve the lighting inside the drying room 1, making it easier for operators to see the condition of each part and improving the accuracy and efficiency of operation.

[0059] The drying room 1 has an air inlet 10 and an air outlet 11 on the outer side walls on both sides of the door, with the air outlet 11 located above the air inlet 10.

[0060] With this design, firstly, the exhaust vent 11 is on top and the air inlet 10 is on the bottom. By utilizing the principle of natural rising of hot air, a thermal pressure ventilation cycle is formed, which can achieve air renewal and replacement without relying too much on power equipment. This creates a good ventilation environment to help the tobacco leaves absorb water and heat, and improve their quality. Furthermore, the two are placed on the outer walls on both sides of the opening and closing door, which makes the air flow path reasonable, avoids airflow turbulence, and ensures stable ventilation effect.

[0061] Secondly, during the tobacco curing process, the dry air entering through the lower air inlet 10 can dilute the humidity, while the water vapor carried by the hot air is discharged through the upper air outlet 11. This effectively controls the humidity and also helps to regulate the temperature, ensuring a uniform temperature distribution and guaranteeing that the tobacco leaves are cured in a suitable temperature and humidity environment.

[0062] A heat source pump 12 is installed outside the drying room 1.

[0063] The heat pump 12 is existing technology. Its structure, working principle and installation principle are all existing technology and are well known to those skilled in the art. They will not be described in detail here.

[0064] A baffle 13 is inclinedly installed above the top of the drying room 1. Support rods 14 are fixedly connected to the four corners at the bottom of the baffle 13, and the bottom of the support rods 14 are fixedly connected to the top of the drying room 1.

[0065] This design allows the inclined baffle 13 to effectively block rainwater, allowing it to flow to the surrounding area and preventing it from accumulating and seeping on the top of the curing barn 1, thus ensuring the interior remains dry and conducive to tobacco curing. It also guides the drainage flow, coordinating with the drainage facilities to drain water in an orderly manner, preventing water accumulation in the surrounding area, maintaining the stability of the curing barn 1 and its surrounding foundation, and extending its service life.

[0066] Secondly, the baffle 13 can block direct sunlight, reduce the heat absorption of the top of the curing room 1, avoid excessive internal temperature, maintain a suitable temperature environment, and reduce the pressure of cooling and ventilation energy consumption; and the increased spacing enhances the heat insulation performance, which is conducive to creating good temperature and humidity conditions for curing tobacco and ensuring curing quality.

[0067] Furthermore, the support rods 14 at the four corners provide stable support for the baffle 13, making it less likely to shake, shift, or fall when subjected to external forces, thus ensuring its continued function and protecting the surrounding area. At the same time, they can distribute the force on the baffle 13, protect the top of the drying room 1, extend its service life, and reduce maintenance costs.

[0068] The drying room 1 is also equipped with fans, temperature and humidity sensors, heating pipes, control systems, fire prevention facilities, and lighting equipment, depending on the usage requirements.

[0069] The aforementioned fan, temperature and humidity sensor, heating pipeline, control system, fire protection facilities, lighting equipment, etc. are all existing technologies. Their structure, working principle, and installation principle are all existing technologies and are well known to those skilled in the art, so they will not be described in detail here.

[0070] Working principle: When the staff needs to cure the tobacco leaves, they first open the door 7 and enter the curing room 1. When using it, the operator presses the motor 67 lowering button on the control panel to start the motor 67 to rotate forward. After the motor 67 is powered on, it starts to run, driving the gear 66 connected to it to rotate clockwise in the movable groove 62 (assuming that the forward rotation direction is the lowering direction).

[0071] Since gear 66 meshes with rack 64 on the outer wall of the first cigarette rack 3, the rotation of gear 66 causes rack 64 to move downward along mounting plate 61. At the same time, limiting block 65 on the outer wall of the first cigarette rack 3 slides downward synchronously in limiting groove 63. Limiting groove 63 guides and restricts limiting block 65, so that the first cigarette rack 3 can only descend smoothly in the vertical direction, without any unstable situations such as left-right deviation, front-back swaying or rotation. At the same time, as the first cigarette rack 3 descends, the connecting rod 5 at the top drives the second cigarette racks 4 on both sides to descend synchronously, achieving a uniform descent of the entire cigarette rack structure.

[0072] During the operation of motor 67, the operator observes the height scale pre-marked on the mounting plate 61 or uses a height monitoring device installed in the drying room 1 (such as a laser rangefinder and a height sensor, which are existing technologies and will not be described in detail in this embodiment), combined with their own operating habits and height, to determine when the first smoke rack 3 and the second smoke rack 4 have descended to the appropriate height for hanging smoke. When the appropriate height is reached, the operator stops motor 67 by controlling the button to stabilize the first smoke rack 3 and the second smoke rack 4 at this height.

[0073] After the first tobacco rack 3 and the second tobacco rack 4 are stabilized, place the two ends of the prepared tobacco hanging rod (which has been evenly covered with tobacco leaves) at the corresponding positions of the first tobacco rack 3 and the second tobacco rack 4 respectively. After the tobacco is hung, start the motor 67 to reverse through the control console or control button. The motor 67 starts to rotate counterclockwise, driving the gear 66 to rotate in the opposite direction in the movable groove 62.

[0074] As gear 66 reverses, the rack 64 meshing with it begins to move upward, thereby driving the first cigarette rack 3 to rise. The limiting blocks 65 on both sides of the first cigarette rack 3 slide upward in the limiting groove 63 to ensure that the first cigarette rack 3 remains vertical and stable during the rising process. At the same time as the first cigarette rack 3 rises, the second cigarette racks 4 on both sides are driven to rise synchronously through the connecting rod 5.

[0075] According to the baking process requirements and internal space layout of the baking room 1, the target heights of the first smoke rack 3 and the second smoke rack 4 are predetermined. The operator monitors the rising process of the first smoke rack 3 and the second smoke rack 4 through the control console. When the first smoke rack 3 and the second smoke rack 4 rise to the predetermined baking height, the motor 67 is stopped, so that the first smoke rack 3 and the second smoke rack 4 stay at this position and wait for the subsequent baking process to begin.

[0076] After placement, close the door 7, start the heat pump 12 to heat the air inside the drying room 1, exhaust the moisture through the exhaust vent 11, and fresh air enters through the air inlet 10.

[0077] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
