Abstract

This utility model discloses a mechanically linked tobacco loading tray, aiming to solve the problems of cumbersome, inefficient, labor-intensive, and dangerous traditional loading processes. The tray comprises two parallel, U-shaped tobacco beams with multiple trays sliding between them, each tray holding multiple tobacco clips. The innovation lies in the rapid locking and unlocking structure formed between the front and rear trays, consisting of an upper locking part and a lower locking part. During loading, the lower locking clip of the front tray extends out of the frame and rests on the tobacco beam. As the rear tray approaches, the frame pushes the lower locking clip into place, thereby locking the upper locking clip. During unloading, the rear tray drags the front tray out of the tobacco curing room. After the rear tray reaches the lifting platform, the platform descends, and the rear tray moves downwards simultaneously, causing the lower locking clip to disengage from the upper locking clip and unlock, achieving efficient loading and unloading. This structural design not only improves loading efficiency but also enhances operational safety and optimizes space utilization, making it suitable for tobacco loading operations in curing barns.

Description

Technical Field

[0001] This utility model relates to the field of tobacco loading technology, and more specifically to a mechanically linked tobacco loading tray. Background Technology

[0002] A standard air-source heat pump dense curing barn (hereinafter referred to as the curing barn) has a three-layer three-dimensional structure. The bottom layer of the tobacco beams is 1.8 meters above the ground, the middle layer is 2.1 meters above the ground, and the top layer is 2.9 meters above the ground. After fresh tobacco leaves are harvested, they need to be quickly loaded into the curing barn for curing. The traditional manual loading process is cumbersome: first, the tobacco leaves are loaded into tobacco clips, and then the clips are loaded one by one onto the tobacco beams of the curing barn. Each tobacco clip can hold about 20 kilograms of tobacco leaves, and a single curing barn can hold about 380 tobacco clips. According to practical calculations, it takes 3 strong laborers working together for 3 hours to complete the loading of tobacco into one curing barn. If 20 curing barns are handled at the same time, the manpower demand will increase significantly. In addition, tobacco curing takes place from July to September, and the temperature inside the curing barn is unbearable. The middle and top layer tobacco beams are high, which not only leads to high labor intensity for workers, but also poses certain safety hazards. Moreover, long-term high-intensity work can easily cause fatigue, resulting in a significant decrease in loading efficiency, which seriously affects the progress and quality of tobacco curing.

[0003] Currently, most tobacco loading equipment on the market relies on lifting principles for operation. However, this traditional equipment has revealed numerous drawbacks in practical applications. First, during loading, tobacco clips must be placed into the curing barn one by one, a cumbersome process that severely restricts work efficiency. Second, mechanized unloading is not considered; unloading is done manually, requiring the removal of each tobacco clip, a time-consuming and labor-intensive operation. Third, due to the extremely limited space inside the curing barn—its single-row structure is only 1.39 meters wide but 8 meters long, resulting in a long and narrow layout—the loading and unloading trolleys face strict limitations in size and operation. During entry and exit, the equipment must be repeatedly adjusted to avoid collisions with the barn walls, a process that is not only cumbersome but also poses a potential threat to the safety of on-site personnel. Although this type of equipment alleviates the intensity of manual labor to some extent, it reveals problems such as low operating efficiency, insufficient operational flexibility, and high safety risks in actual operation, making it difficult to meet the demands of efficient and safe production.

[0004] Therefore, how to achieve full automation of tobacco leaf loading and unloading, and effectively ensure the continuity and efficiency of the entire tobacco leaf curing and processing process, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a mechanically linked tobacco leaf loading tray, which aims to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mechanically linked tobacco loading tray includes two parallel Z-shaped tobacco beams, with multiple trays slidably disposed between the two Z-shaped tobacco beams, and multiple tobacco clips mounted on the trays; a quick locking and unlocking structure is formed between two corresponding trays;

[0008] The quick locking and unlocking structure includes an upper locking part located at the front end of the tray and a lower locking part located at the rear end of the tray; the upper locking part includes an upper locking buckle rotatably connected to the inner wall of the tray frame via a shaft one, and the lower part of the shaft one has an upper locking buckle support block fixed to the inner wall of the frame and abutting against the upper locking buckle; the lower locking part includes a lower swing arm rotatably connected to the inner wall of the frame via a shaft two, and the lower swing arm is rotatably connected to a spoon-shaped lower locking buckle via a shaft three.

[0009] When two trays need to be connected, the lower latch of the front tray rotates and extends out of the frame and rests on the Z-shaped cigarette beam. The rear tray moves closer, allowing its frame to push the lower latch to rotate and lift into its frame, and push the upper latch to rotate to achieve a locking. When two trays need to be separated, the rear tray is pulled away from the Z-shaped cigarette beam and moves downward, causing the lower latch to rotate and disengage from the upper latch.

[0010] Through the above technical solution, this utility model innovatively designs a locking structure to create a pallet linkage pushing system. The locking mechanism is automatically triggered during tobacco loading and intelligently disengaged during tobacco unloading. The entire process eliminates the need for loading and unloading equipment to enter and exit the narrow space of the tobacco curing barn, effectively avoiding safety risks such as collisions and falls, and providing reliable safety for operators. The ingenious locking structure design achieves automatic locking and disengagement functions. After the two pallets are tightly fitted, the tobacco clips can be cleverly stored inside the pallets, fully freeing up space in the tobacco curing barn beams and effectively improving the loading utilization rate of the tobacco curing barn.

[0011] Preferably, in the above-mentioned mechanically linked tobacco loading tray, the bottom edges of both sides of the tray frame are equipped with needle roller bearings to achieve a sliding fit between the frame and the Z-shaped tobacco beam. By setting needle roller bearings on the bottom edges of both sides of the tray frame to achieve a sliding fit between the frame and the Z-shaped tobacco beam, the movement resistance during the loading and unloading of tobacco is significantly reduced, effectively improving the smoothness of tray movement, reducing energy consumption, and extending the service life of the equipment.

[0012] Preferably, in the aforementioned mechanically linked tobacco loading tray, the bottom edges of both sides of the tray's frame are equipped with automatic guide blocks. Equipped with a precision guiding mechanism, it features automatic positioning and guiding functions, accurately limiting the tray's lateral displacement, and avoiding obstacles such as bolts on the tobacco beams in real time. This ensures the tray operates smoothly during loading and unloading, reducing equipment wear and the risk of malfunction.

[0013] Preferably, in the aforementioned mechanically linked tobacco loading tray, a tobacco clamp limiting block is fixed at the front end of the tray to prevent the tobacco clamp from detaching from the front end during loading. A tobacco clamp limiting block is also fixed at the rear end of the tray to prevent the tobacco clamp from detaching from the rear end during loading, thereby improving the stability and reliability of tobacco loading.

[0014] Preferably, in the above-mentioned mechanically linked tobacco loading tray, when the lower swing arm rotates to abut against the rear bottom edge of the tray's frame, the lower locking buckle naturally hangs down outside the frame. When the tray is pushed onto the Z-shaped tobacco beam and the Z-shaped tobacco beam contacts the lower locking buckle, it lifts the lower locking buckle and causes it to rest on the Z-shaped tobacco beam, further optimizing the automatic positioning and locking function of the locking buckle.

[0015] Preferably, in the above-mentioned mechanically linked tobacco loading tray, when it is necessary to insert the tobacco clip into the frame of the tray, the lower locking buckle is pushed upward, causing the lower swing arm to rotate forward until the end of the lower locking buckle abuts against the top edge of the rear end of the frame of the tray, completing the folding of the lower locking buckle and the lower swing arm, so that a clearance space for the tobacco clip to enter is formed below the lower locking buckle and the lower swing arm, simplifying the tobacco clip insertion operation process.

[0016] Preferably, in the above-mentioned mechanically linked tobacco loading tray, when both trays connected front and rear are located on the Z-shaped tobacco beam, the lower and upper locking buckles connected front and rear remain locked. When the rearmost tray of the two connected trays disengages from the Z-shaped tobacco beam and moves downward, the lower and upper locking buckles connected front and rear disengage and unlock, realizing the automatic disengagement function between the trays and facilitating unloading operations.

[0017] Preferably, in the above-mentioned mechanically linked tobacco loading tray, the bottom edge of the front end of the tray frame can lift the lower latch to connect with the hook on the upper latch, ensuring a stable connection between the latches of the trays and improving the stability of the trays during the loading process.

[0018] Preferably, in the above-mentioned mechanically linked tobacco loading tray, each tray has 5 tobacco clips. Compared with the traditional loading method, this can significantly increase the tobacco loading density in the curing barn and improve the space utilization of the curing barn.

[0019] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a mechanically linked tobacco leaf loading tray, which has the following beneficial effects:

[0020] 1. High-efficiency loading and unloading innovation: Breaking through the bottleneck of traditional loading efficiency, a single pallet can load 5 tobacco clips at a time. With the help of professional loading and unloading equipment, it can realize the rapid and continuous loading and unloading of tobacco leaves in the entire tobacco barn, significantly improving the work efficiency and greatly shortening the tobacco loading cycle.

[0021] 2. Enhanced Safety Protection: The innovative locking structure design creates a pallet linkage pushing system. The locking mechanism is automatically triggered when loading tobacco and the locking mechanism is intelligently released when unloading tobacco. The entire process eliminates the need for loading and unloading equipment to enter and exit the narrow space of the drying room, effectively avoiding safety risks such as collisions and falls, and providing reliable safety protection for operators.

[0022] 3. Optimized Space Utilization: The ingeniously designed locking structure not only achieves automatic locking and unlocking functions, but also allows the cigarette clips to float in mid-air during the loading stage, ensuring smooth and interference-free loading. After the two trays fit tightly together, the cigarette clips can be cleverly stored inside the trays, fully freeing up space in the tobacco room beams and effectively improving the loading utilization rate of the tobacco room.

[0023] 4. Precise Guidance Guarantee: Equipped with a precise guidance mechanism, it has automatic positioning and guidance functions, which can accurately limit the lateral displacement of the pallet and avoid obstacles such as bolts on the smoke beam in real time, ensuring the smooth operation of the pallet during loading and unloading, and reducing equipment wear and the risk of failure.

[0024] 5. Significantly reduced resistance: The bottom of the pallet is equipped with a high-precision needle roller bearing. Through optimized rolling friction design, the movement resistance during the loading and unloading of tobacco is greatly reduced, which effectively improves the smoothness of pallet movement, reduces energy consumption, and extends the service life of the equipment.

[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0038] Refer to Attached Figure 1 to Attached Figure 2 , the embodiments of the present utility model disclose a mechanically linked tobacco loading tray for a kang, including two parallel U-shaped tobacco beams 1, between which a plurality of trays 2 are slidably provided, and a plurality of cigarette clips 3 are installed on the trays 2; a quick locking and unlocking structure is formed between two front and rear corresponding trays 2; [[ID=3⑥]]

[0039] The quick locking and unlocking structure includes an upper lock catch part provided at the front end of the tray and a lower lock catch part provided at the rear end of the tray; the upper lock catch part includes an upper lock catch 203 rotatably connected to the inner wall of the frame 201 of the tray 2 through a shaft 202, and a lower part of the shaft 202 has an upper lock catch support block 204 fixed to the inner wall of the frame 201 and abutted against the upper lock catch 203; the lower lock catch part includes a lower swing arm 206 rotatably connected to the inner wall of the frame 201 through a shaft 205, and the lower swing arm 206 is rotatably connected through a shaft 207 to a spoon-shaped lower lock catch 208;

[0040] When two trays 2 need to be connected, the lower latch 208 of the front tray 2 rotates and extends out of the frame 201 and rests on the Z-shaped cigarette beam 1. The rear tray 2 moves closer, so that its frame 201 can push the lower latch 208 to rotate and lift into its frame 201, and push the upper latch 203 to rotate to achieve a locking. When two trays 2 need to be separated, the rear tray 2 is pulled away from the Z-shaped cigarette beam 1 and moves downward, so that the lower latch 208 rotates and disengages from the upper latch 203.

[0041] Through scientific layout and precise assembly, each component forms a stable and flexible mechanical system, ensuring precise guidance and reliable fixation during the loading, transportation and unloading of tobacco leaves, providing solid hardware support for tobacco curing operations.

[0042] See appendix Figure 2 and attached Figure 3 The bottom edges of the frame 201 of the tray 2 are equipped with needle roller bearings 209 to achieve sliding fit between the frame 201 and the Z-shaped smoke beam 1.

[0043] To further optimize the above technical solution, the bottom edges of both sides of the frame 201 of the tray 2 have automatic guide blocks 210.

[0044] To further optimize the above technical solution, a cigarette clip limiting block 211 is fixed at the front end of the tray 2 to prevent the cigarette clip 3 from coming out from the front end when it is inserted.

[0045] To further optimize the above technical solution, when the lower swing arm 206 rotates to abut against the rear bottom edge of the frame 201 of the tray 2, the lower locking buckle 208 naturally hangs down outside the frame 201. When the tray 2 is pushed onto the zigzag cigarette beam 1 and the zigzag cigarette beam 1 contacts the lower locking buckle 208, the lower locking buckle 208 is lifted up and rests on the zigzag cigarette beam 1.

[0046] To further optimize the above technical solution, when it is necessary to insert the cigarette clip 3 into the frame 201 of the tray 2, push the lower locking buckle 208 upward, so that the lower swing arm 206 rotates forward until the end of the lower locking buckle 208 abuts against the top edge of the rear end of the frame 201 of the tray 2, completing the folding of the lower locking buckle 208 and the lower swing arm 206, so that a clearance space for the cigarette clip 3 to enter is formed below the lower locking buckle 208 and the lower swing arm 206.

[0047] See appendix Figure 4The loading direction of the tobacco clips 3 follows the operating procedure of moving from outside the tobacco room to inside (as shown in the figure, from right to left). During the tobacco loading preparation stage, the lower locking buckle 208 and the lower swing arm 206 need to be rotated to the specific angle shown in the figure. At this point, the two achieve mechanical balance under the combined action of gravity and the frame 201, stably suspending in the air, reserving ample operating space for the rapid assembly of the tobacco clips 3. Once a single pallet 2 has loaded 5 tobacco clips, the tobacco clip limiting block 211 immediately comes into play. Through a precise locking design, it effectively prevents the tobacco clips 3 from accidentally falling off during subsequent assembly and transportation, comprehensively ensuring the safety and stability of tobacco loading and significantly improving operational reliability.

[0048] To further optimize the above technical solution, when both trays 2 connected at the front and rear are located on the Z-shaped tobacco beam 1, the lower locking buckle 208 and the upper locking buckle 203 connected at the front and rear are always locked. When the rear tray 2 of the two trays connected at the front and rear is disengaged from the Z-shaped tobacco beam 1 and moves downward, the lower locking buckle 208 and the upper locking buckle 203 connected at the front and rear are disengaged and unlocked.

[0049] To further optimize the above technical solution, the bottom edge of the front end of the frame 201 of the tray 2 can lift the lower latch 208 to connect with the hook on the upper latch 203.

[0050] In this embodiment, each tray 2 has 5 cigarette clips 3.

[0051] See appendix Figure 5 After the tobacco clip 3 is loaded, it enters the state shown in 5a. The operator manually adjusts the lower swing arm 206 and the lower locking buckle 208. Under the action of gravity, the lower swing arm 206 is stably placed on the surface of the tobacco clip 3, and the lower locking buckle 206 hangs down naturally, forming an initial locking preparation posture. When the lifting mechanism accurately raises the pusher to the corresponding height of the tobacco beam (5b), the loading equipment applies a pushing force into the tobacco room (referred to as to the left). The tray 2, with its built-in guide mechanism, can smoothly embed itself along the U-shaped tobacco beam 1. The automatic guide block 210 at the bottom of the tray 2 can limit the lateral position of the tray 2, effectively avoiding the risk of interference with the tobacco beam bolts; while the application of the needle roller bearing 209 greatly reduces the movement resistance of the tray 2. When the tray 2 is fully pushed into the U-shaped tobacco beam 1, the lower locking buckle 208 is interfered with by the structure of the U-shaped tobacco beam 1 and automatically falls into the plane of the U-shaped tobacco beam 1, completing the initial positioning.

[0052] During the continuous advancement process (5c), the subsequent tray 2 and the preceding tray 2 are mechanically linked. The subsequent tobacco clip 3 contacts the lower locking buckle 208 of the preceding tray 2, creating interference. As the subsequent tray 2 continues to move to the left, the lower locking buckle 208 rotates counterclockwise around the rotation axis and rises in height. After the lower locking buckle 208 has fully risen to the upper surface of the tobacco clip 3 (5d), the force continues to be applied, and the lower locking buckle 208 and the upper locking buckle 203 create secondary interference, causing the upper locking buckle 203 to rotate clockwise and rise. Until the edges of the two trays 2 are tightly fitted (5e), ​​and the hooks are completely retracted inside the trays 2, the mechanical locking process between the trays 2 is successfully completed. Subsequently, through the linkage transmission mechanism of the subsequent tray 2 pushing the preceding tray 2, the seamless connection and installation of the entire row of trays 2 in the curing room can be achieved, efficiently completing all loading operations.

[0053] In the tobacco unloading scenario, as shown in 6a, when the subsequent tray 2 moves to the right, its upper locking buckle 203 precisely hooks the lower locking buckle 208 of the preceding tray 2. Due to the height of the tobacco clip 3, the two hooks form a stable locked state, achieving reliable binding between the trays 2 and providing a solid connection foundation for overall unloading. As the subsequent tray 2 continues to move to the outside of the tobacco house (6b), the lifting mechanism is activated, causing the tray 2 to move downward. At this time, under its own gravity, the lower locking buckle 208 of the preceding tray 2 rotates clockwise around its rotation axis until it naturally hangs down, making enough space for the subsequent tray 2 to move downward, ultimately enabling the two trays 2 to be completely separated, completing the key decoupling operation in the tobacco unloading process.

[0054] This embodiment innovatively designs a mechanically linked pallet system. The loading equipment is placed outside the tobacco curing barn. During loading, a pushing mechanism loads pallets one by one onto the tobacco beams. The subsequently loaded pallets push the preceding pallets deeper into the curing barn, achieving continuous loading of the entire row of tobacco leaves. Simultaneously, the pallet locks engage, preparing for unloading. During unloading, by pulling the pallet closest to the curing barn entrance from each layer of tobacco beams in the reverse direction onto the equipment lifting system, the entire row of pallets moves outward synchronously. As the pallets descend with the lifting system, the linkage device automatically disengages. This front-and-back pallet linkage loading and unloading mode eliminates the need for the equipment to enter the curing barn, reducing the occurrence of safety accidents, significantly improving tobacco loading and unloading efficiency, reducing labor intensity, increasing equipment utilization, and achieving automated and intensive management of tobacco curing operations.

[0055] This embodiment designs a guiding mechanism that adaptively guides the pallet during the docking process with the tobacco beam, achieving automatic calibration and precise positioning of the pallet's lateral position, ensuring efficient and error-free loading. As the pallet moves along the tobacco beam, this guiding mechanism avoids obstacles such as locking bolts on the beam and columns, ensuring smooth and stable pallet operation, effectively preventing collisions and wear, and significantly improving the safety and reliability of the tobacco loading and unloading process.

[0056] This tray achieves a perfect balance between loading capacity and practicality in its structural design. By optimizing the load-bearing layout and tray structure, it can stably load multiple tobacco clips at once while ensuring the tray is sturdy, durable, and easy to operate. This design significantly improves work efficiency, effectively shortens operation time, and provides strong support for the efficient operation of the tobacco curing process.

[0057] This tray is the core load-bearing tool used in the self-developed and publicly disclosed utility model patent "CN119699623A A Tobacco Leaf Loading Equipment". It features a built-in mechanical linkage device that enables automatic locking and unlocking during operation. During loading, the loading equipment is placed outside the curing barn and locked to the barn pillars to prevent misalignment. The tray is placed on the equipment's lifting device. One tray can hold five tobacco clips. Through coordinated operation with the loading equipment, five tobacco clips can be loaded automatically at once. Adjacent trays loaded onto the tobacco beams are locked together by the latches, completing the loading process. After the tobacco leaves are cured, the equipment's propulsion system pulls the tray closest to the curing barn door onto the lifting system. Under the action of the latches, the inner tray is pulled outwards. As the tray descends with the lifting system, it automatically unlocks, allowing the trays to be unloaded one by one. The tray design enables fully automated tobacco leaf loading and unloading, effectively ensuring the continuity and efficiency of the entire tobacco curing process.
