Description

Technical Field

[0001] This application belongs to the field of tobacco processing technology, specifically relating to a movable tobacco rack cart for drying tobacco leaves in a curing barn. Background Technology

[0002] Currently, in the tobacco processing flow, fixed tobacco racks are mostly used as the supporting structure for tobacco leaves in the drying area. These racks are permanently connected to the walls and supports of the drying area and cannot be moved. In practice, tobacco clips need to be hung on the fixed tobacco racks, and then the tobacco leaves on the racks are dried using hot air drying or other methods by drying equipment.

[0003] Because the tobacco rack is fixed inside the drying area, operators need to enter the small space inside the drying area to work when loading tobacco, which restricts their range of movement and makes it difficult to quickly and neatly hang the tobacco leaves on the tobacco clips. When unloading tobacco, the operators are also restricted by the enclosed space of the drying area and the fixed position of the tobacco rack, which hinders their actions of picking up and putting down the tobacco clips and tobacco leaves, which is time-consuming and laborious and seriously affects the overall processing efficiency.

[0021] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0022] See Figure 1 As shown in the embodiments of this application, a movable tobacco rack cart for drying tobacco leaves in a curing barn is provided, comprising: a loading and unloading area and a drying area arranged sequentially; a tobacco rack cart, which is movably arranged in the loading and unloading area and the drying area; the tobacco rack cart includes a movable frame 1 and a tobacco hanging rack 2 detachably arranged on the movable frame 1, the tobacco hanging rack 2 being used to clamp the tobacco leaves to be dried; wherein, the tobacco rack cart is configured to: complete the clamping operation of the tobacco leaves to be dried on the tobacco hanging rack 2 in the loading and unloading area, and the operation of installing the tobacco hanging rack 2 with the tobacco leaves to be dried onto the movable frame 1; and the disassembly operation of the tobacco hanging rack 2 containing the dried tobacco leaves from the movable frame 1 is also carried out in the loading and unloading area.

[0023] The movable tobacco rack cart for drying tobacco leaves in a curing barn provided in the embodiments of this application, by setting up a tobacco rack cart that can move between the loading and unloading area and the drying area, allows operators to complete the loading and unloading operations without entering the drying area, effectively improving the efficiency of loading and unloading. The specific operation process is as follows: In the loading stage, using the detachable connection structure between the tobacco rack 2 and the movable frame 1, the tobacco leaves to be dried are first clamped onto the tobacco rack 2 in the loading and unloading area. After completion, the tobacco rack 2 with the clamped tobacco leaves is installed onto the movable frame 1, and finally the movable frame 1 is moved to the drying area. In the unloading stage, after the tobacco leaves are dried, the movable frame 1 is first moved to the loading and unloading area, and then the tobacco rack 2 carrying the dried tobacco leaves is directly removed from the movable frame 1 in the loading and unloading area, so that the tobacco leaves can be further processed.

[0024] The drying area can be a curing barn or similar structure, equipped with drying equipment such as hot air devices and temperature control systems for tobacco leaf drying operations.

[0025] Specifically, when the drying area is a curing barn, the loading and unloading area is a relatively open space outside the curing barn, which can be used by operators to process tobacco leaves.

[0026] Among them, a smoke rack cart is movably installed between the loading and unloading area and the drying area. The smoke rack cart is made of high-temperature resistant steel, which can maintain good wear resistance and load-bearing capacity in high-temperature environments.

[0027] The tobacco rack cart includes a mobile frame 1 and a tobacco hanging rack 2. The mobile frame 1 is mobile, for example, equipped with rollers and a track-adaptive structure, used to support the tobacco hanging rack 2 and facilitate transfer between areas. The tobacco hanging rack 2 is used to directly clamp the tobacco leaves to be dried, for example, by fixing the tobacco leaves with tobacco clips, clamps, or other structures, and is detachably connected to the mobile frame 1 using connection structures such as buckles, slots, and bolts.

[0028] Specifically, in practical applications, during the loading stage, operators arrange the tobacco leaves to be dried in the loading and unloading area and clamp them one by one onto the tobacco hanging rack 2, completing the combination of the tobacco leaves to be dried and the tobacco hanging rack 2. After the tobacco hanging rack 2 is full of tobacco leaves, it is installed onto the mobile frame 1, completing the overall assembly of the tobacco leaves to be dried, the tobacco hanging rack 2, and the mobile frame 1. During the drying stage, the mobile frame 1 carries the tobacco hanging rack 2 containing the tobacco leaves to be dried from the loading and unloading area to the drying area. In the drying area, the drying equipment is started to dry the tobacco leaves on the tobacco hanging rack 2. During the unloading stage, after the tobacco leaves are dried, the mobile frame 1 moves the tobacco hanging rack 2 carrying the dried tobacco leaves from the drying area back to the loading and unloading area. Operators directly remove the tobacco hanging rack 2 from the mobile frame 1 in the loading and unloading area and perform subsequent processing on the dried tobacco leaves on the tobacco hanging rack 2, such as collection and grading.

[0029] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 and Figure 2 As shown, the mobile frame 1 is equipped with four corners and the middle of the bottom of the mobile frame 1. A guide rail 4 is provided between the loading and unloading area and the drying area. The mobile wheels 3 are rotatably mounted on the guide rail 4. The guide rail 4 is used to form a travel path for the mobile frame 1 to travel, so as to guide the mobile frame 1 to move back and forth between the loading and unloading area and the drying area.

[0030] In this embodiment, the movable wheels 3 are distributed at the four corners and the center of the bottom, which can evenly distribute the weight of the tobacco rack 2 and the tobacco leaves, avoiding tilting or swaying caused by the shift of the center of gravity during movement. This is especially beneficial when carrying a large amount of tobacco leaves, as it reduces the risk of tipping over. The cooperation between the guide rail 4 and the movable wheels 3 forms a fixed travel path, limiting the deviation of the movable frame 1 and preventing it from deviating from the predetermined route during transport, thus reducing the risk of collision with the inner wall of the drying area or other equipment.

[0031] Among them, wheel seats are fixedly installed at the four corners and the middle of the bottom of the mobile frame 1, and the mobile wheels 3 are installed on the wheel seats through high temperature resistant bearings.

[0032] The guide rail 4 is laid between the loading / unloading area and the drying area, forming a channel connecting the two areas. The movable wheels 3 are rotatably mounted on the guide rail 4, meaning they can roll along the extension direction of the guide rail 4, creating a stable guiding connection. Here, the main function of the guide rail 4 is to define the travel path of the movable frame 1, ensuring that the movable frame 1 can only move back and forth between the loading / unloading area and the drying area along the direction of the guide rail 4, without deviating from the predetermined route. For example, when the movable frame 1 moves from the loading / unloading area to the drying area, it can accurately enter the designated position in the drying area under the guidance of the guide rail 4; conversely, when returning from the drying area to the loading / unloading area, it can also accurately return to the loading / unloading area along the guide rail 4.

[0033] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 As shown, the mobile frame 1 includes: a mobile base 11 and at least three brackets 12 fixedly mounted on the mobile base 11; the at least three brackets 12 are arranged at equal intervals along the length or width direction of the mobile base 11 and are perpendicular to the top surface of the mobile base 11; wherein, at least four layers of support frames are arranged vertically between two adjacent brackets 12, and the support frames include two oppositely arranged tobacco-carrying beams 13, and the two ends of the tobacco hanging frame 2 can be respectively mounted on the two tobacco-carrying beams 13.

[0034] In this embodiment, at least three hanging racks 12 are arranged at equal intervals along the movable base 11, forming a multi-layered, multi-column three-dimensional loading structure in conjunction with at least four layers of support frames between adjacent hanging racks 12. This allows for the mounting of more tobacco hanging racks 2 within the limited space of the movable frame 1, thereby increasing the number of tobacco leaves to be dried in a single batch and improving the equipment's operating capacity. Simultaneously, the support frame employs a structure of two oppositely arranged tobacco-bearing beams 13. The two ends of the tobacco hanging racks 2 can be directly mounted on the tobacco-bearing beams 13, forming a simple and reliable detachable connection without the need for complex locking devices. Operators can quickly complete the installation and disassembly of the tobacco hanging racks 2, further improving the operational efficiency of the loading and unloading area.

[0035] Among them, the mobile base 11 serves as the basic load-bearing structure of the entire frame, and the aforementioned mobile wheels 3 are installed at the bottom to enable the overall movement of the cigarette frame vehicle.

[0036] Among them, the hanging bracket 12 is a vertical support, with a minimum of three, which is fixedly installed on the top surface of the movable base 11 and extends upward perpendicular to the top surface of the base.

[0037] Specifically, at least three hangers 12 are arranged along the length or width of the movable base 11. The hangers 12 maintain equal distances, forming a regular arrangement that ensures uniform stress on the subsequently mounted tobacco racks 2 and provides consistent ventilation space between the tobacco leaves to be dried. Here, the movable base 11 and its at least three hangers 12 are all welded from high-temperature and corrosion-resistant galvanized steel, maintaining structural stability and resisting deformation even at high temperatures of 100℃~150℃.

[0038] Between two adjacent hangers 12, at least four layers of support frames are arranged vertically. That is, between each pair of adjacent hangers 12, multiple layers of horizontal support structures are arranged from top to bottom.

[0039] Specifically, each support frame consists of two oppositely arranged smoke-carrying beams 13. For example, one smoke-carrying beam 13 is fixed on the left bracket 12, and another smoke-carrying beam 13 is fixed at the corresponding position on the adjacent right bracket 12, forming a pair. Here, the cross-sectional shape of the smoke-carrying beam 13 is L-shaped, and its horizontally extended part, that is, the flange in the L-shaped structure that is in a horizontal state after connecting with the bracket 12, forms a support surface. The two ends of the smoke-carrying frame 2 can be placed on the horizontal support surfaces of the two opposite smoke-carrying beams 13 at the same height, thereby realizing the detachable connection between the smoke-carrying frame 2 and the mobile frame 1.

[0040] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 As shown, a reinforcing connecting plate 14 is provided at the connection between the hanging bracket 12 and the movable base 11. The reinforcing connecting plate 14 includes a first end face and a second end face that are perpendicular to each other. One of the first end face and the second end face is fixedly connected to the side of the hanging bracket 12 on which the support frame is provided, and the other end face is fixedly connected to the top surface of the movable base 11.

[0041] In this embodiment, the reinforcing connecting plate 14 is fixedly connected to the side of the hanger 12 and the top surface of the movable base 11 through the first and second end faces that are perpendicular to each other, forming a reinforcing structure similar to a right-angle support. This can effectively disperse the vertical load and horizontal force borne by the hanger 12, and prevent the connection between the hanger 12 and the base from loosening or breaking due to stress concentration.

[0042] The reinforcing connecting plate 14 is a component with a right-angled structure, comprising two mutually perpendicular first end faces and a second end face. Here, the first end face and the second end face can be understood as a right-angled triangular metal plate or profile.

[0043] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1As shown, the bracket 12 is a frame structure, and the frame structure is provided with at least two diagonal braces 15, which are segmented diagonal supports; wherein, on the frame structures of two adjacent brackets 12, the segmented diagonal supports of the at least two diagonal braces 15 are arranged in opposite ways.

[0044] In this embodiment, the frame structure itself is lightweight and has a strong load-bearing capacity. With the diagonal support of at least two segmented diagonal braces 15, it can form a multi-node triangular stable structure, effectively dispersing the longitudinal pressure and lateral force borne by the hanger 12.

[0045] Among them, the bracket 12 is a three-dimensional frame composed of vertical bars, horizontal bars, etc., which can reduce the overall weight while ensuring a certain strength and provide a support point for the installation of the diagonal tie rod 15.

[0046] Among them, at least two diagonal tie rods 15 on the hanger 12 are in the shape of a broken line, which divides the frame structure into multiple triangular areas, thereby enhancing the overall deformation resistance of the frame, especially its ability to resist lateral forces.

[0047] Specifically, on the frame structures of two adjacent brackets 12, the segmented diagonal support directions of the tie rods 15 are opposite. For example, if the first tie rod 15 of one bracket 12 connects diagonally from the lower part of the left vertical bar to the upper right and then to the middle of the right vertical bar, and the second tie rod 15 connects diagonally from the middle of the right vertical bar to the upper left and then to the upper part of the left vertical bar; then the first tie rod 15 of the adjacent bracket 12 can connect diagonally from the lower part of the right vertical bar to the upper left and then to the middle of the left vertical bar, and the second tie rod 15 connects diagonally from the middle of the left vertical bar to the upper right and then to the upper part of the right vertical bar. Thus, the two adjacent brackets 12 restrain each other, preventing the entire mobile frame 1 from shifting or swaying due to the tilt of the brackets 12, further ensuring structural stability.

[0048] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 As shown, the mobile frame 1 includes a top frame beam 16, and the tops of at least three hangers 12 are connected via the top frame beam 16.

[0049] In this embodiment, by setting the top frame beam 16, the scattered hangers 12 can be connected into a whole at the top, so that the originally independent multiple hangers 12 form a whole structure that shares the force, and avoids the individual hangers 12 from shaking or tilting independently due to uneven force.

[0050] The top frame beam 16 can be a transverse connecting member with a frame structure, which is set along the length or width of the movable base 11 and is consistent with the arrangement direction of the hanger 12.

[0051] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 As shown, both ends of the tobacco-carrying beam 13 are provided with stop blocks 17, which are used to limit the tobacco hanging frame 2 erected on the tobacco-carrying beam 13 in the length direction of the tobacco-carrying beam 13.

[0052] In this embodiment, the stop 17, through its physical blocking effect, can limit the displacement of the tobacco rack 2 along its length on the tobacco carrying beam 13 caused by external forces, such as the shaking, vibration, or tilting of the mobile frame 1. For example, when the mobile frame 1 starts, stops, or passes over uneven roads, the tobacco rack 2 will not slip off both ends of the tobacco carrying beam 13 due to inertia, ensuring that the tobacco leaves are stably placed.

[0053] Among them, the baffle 17 is installed at both ends of the smoke-carrying beam 13, that is, at the two ends of the length direction of the smoke-carrying beam 13.

[0054] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 As shown, at least four layers of support frames include a first support frame, a second support frame, a third support frame, and a fourth support frame arranged sequentially from top to bottom; wherein, the interval between the first support frame and the second support frame is 0.8m to 1.0m, the interval between the second support frame and the third support frame is 0.8m to 1.0m, the interval between the third support frame and the fourth support frame is 0.8m to 1.0m, and the interval between the fourth support frame and the movable base 11 is 1.1m to 1.3m.

[0055] In this embodiment, the intervals between the first and second support frames, the second and third support frames, and the third and fourth support frames are all 0.8m to 1.0m. This spacing provides relatively uniform ventilation space for the tobacco leaves on the tobacco rack 2. During the drying process, the drying medium, such as hot air, can circulate relatively evenly between the layers, avoiding airflow obstruction around some tobacco leaves due to excessive differences in the spacing between upper and lower layers, thereby reducing uneven drying and ensuring that tobacco leaves of different grades can be dried under similar conditions. The interval between the fourth support frame and the movable base 11 is 1.1m to 1.3m, which is larger than the spacing between the upper support frames, providing more sufficient circulation space for the return airflow. During the drying process, the return air formed after the hot air exchanges heat with the upper tobacco leaves needs to converge downwards from the gaps between the layers to the bottom return air area. The larger bottom spacing reduces the resistance of the return airflow, avoiding airflow congestion due to narrow space and ensuring smooth return airflow.

[0056] The distance between the first and second support frames can be 0.8m, 0.9m, or 1.0m, etc. It is understood that the distance between the first and second support frames can also be other values ​​besides those mentioned above, as long as the distance between the first and second support frames is within the range of 0.8m to 1.0m. In this embodiment, the distance between the first and second support frames is preferably 0.9m.

[0057] The interval between the second and third support frames can be 0.8m, 0.9m, or 1.0m, etc. It is understood that the interval between the second and third support frames can also be other values ​​besides those mentioned above, as long as the interval between the second and third support frames is within the range of 0.8m to 1.0m.

[0058] The interval between the third and fourth support frames can be 0.8m, 0.9m, or 1.0m, etc. It is understood that the interval between the third and fourth support frames can also be other values ​​besides those mentioned above, as long as the interval between the third and fourth support frames is within the range of 0.8m to 1.0m.

[0059] The distance between the fourth support frame and the first movable base 11 can be 1.1m, 1.2m, or 1.3m, etc. It is understood that the distance between the fourth support frame and the first movable base 11 can also be other values ​​besides those mentioned above, as long as the distance between the fourth support frame and the first movable base 11 is within the range of 1.1m to 1.3m.

[0060] Specifically, in this embodiment, the intervals between the first and second support frames, between the second and third support frames, and between the third and fourth support frames are the same, preferably 0.9m. The interval between the fourth support frame and the first movable base 11 is greater than 0.9m, preferably 1.2m.

[0061] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 As shown, the drying area is configured to accommodate multiple tobacco rack carts; the interval between two adjacent tobacco rack carts is 3cm to 5cm, and the interval between each tobacco rack cart and the side wall of the drying area is 3cm to 5cm.

[0062] In this embodiment, the 3cm to 5cm spacing between adjacent tobacco racks and between the tobacco racks and the side walls of the drying zone provides ample channels for airflow during the drying process. This allows hot air to flow more evenly across each tobacco rack, preventing localized airflow obstruction due to insufficient spacing and ensuring that all tobacco leaves in the racks receive sufficient hot air, thus improving drying efficiency.

[0063] The spacing between two adjacent smoke rack carts is the same as the spacing between each smoke rack cart and the side wall of the drying area.

[0064] Specifically, the interval between two adjacent smoke rack carts and the interval between each smoke rack cart and the side wall of the drying zone can be 3cm, 4cm, or 5cm, etc. It is understood that the interval between two adjacent smoke rack carts and the interval between each smoke rack cart and the side wall of the drying zone can also be other values ​​besides those mentioned above, as long as they are within the range of 3cm to 5cm. In this embodiment, the interval between two adjacent smoke rack carts and the interval between each smoke rack cart and the side wall of the drying zone is preferably 3cm.

[0065] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 As shown, the cigarette rack 2 includes multiple cigarette clips, which are arranged at equal intervals along the length of the cigarette carrying beam 13; the width of the cigarette clips is 9cm to 13cm, and the interval between two adjacent cigarette clips is 1cm to 2cm.

[0066] In this embodiment, by setting the width of the tobacco clips to 9cm~13cm, sufficient support area is provided for the tobacco leaves. When the tobacco leaves are suspended on the clips, the wider clips reduce the likelihood of the leaves slipping or shifting due to their own weight, ensuring that the tobacco leaves remain stably in the preset position during drying and other processing. The spacing between two adjacent clips is 1cm~2cm. This spacing is neither too large, causing the tobacco leaves to contact and squeeze each other while suspended, thus affecting ventilation; nor too small, hindering airflow and heat transfer. The appropriate gap allows airflow to pass more smoothly through the space between the clips, resulting in more uniform heating of the tobacco leaves, which is beneficial to improving the efficiency and quality of drying and other processing.

[0067] The width of the cigarette clip can be 9cm, 10cm, 11cm, 12cm, or 13cm, etc. It is understood that the width of the cigarette clip can also be other values ​​besides those mentioned above, as long as the width is within the range of 9cm to 13cm. In this embodiment, the preferred width of the cigarette clip is 11cm.

[0068] The spacing between two adjacent cigarette clips can be 1 cm or 2 cm, etc. It is understood that the spacing between two adjacent cigarette clips can also be other values ​​besides those mentioned above, as long as the spacing between two adjacent cigarette clips is within the range of 1 cm to 2 cm. In this embodiment, the spacing between two adjacent cigarette clips is preferably 1 cm.

[0069] Furthermore, a cigarette holder can be used to replace the cigarette clip.

[0070] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0071] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
