Description

Technical Field

[0001] This utility model belongs to the field of tobacco curing and processing technology, specifically relating to a self-propelled intelligent tobacco loading and unloading equipment for tobacco curing barns. Background Technology

[0002] In the tobacco curing process, loading and unloading of tobacco leaves is a crucial step in the operation of the curing barn. Existing curing barns include those with brick-concrete structures and those with light steel insulated panels. The interior floors of these barns are either hardened or unhardened. Most curing barn floors are unhardened, and even those that are hardened often have poor flatness, posing a challenge to the stable operation of loading and unloading equipment. In current tobacco curing processes, curing barns typically have 3-4 layers of tobacco hanging racks, each spaced approximately 800mm apart, reaching a height of about 3.5 meters. A full load of tobacco leaves weighs about 15kg, making the loading and unloading operation quite strenuous. Traditional loading and unloading methods rely on manual ladder work: one worker passes the tobacco racks on the ground, while another worker stands on the ladder to receive and hang them. After hanging 3-4 racks, the ladder needs to be moved to continue the work. This method has the following drawbacks: uneven ground causes uneven stress on the ladder, making it prone to tilting; workers at heights are prone to accidents due to muscle fatigue from prolonged heavy loads; frequent ladder movements are time-consuming and laborious, and manually lifting the cigarette clips to higher floors requires a lot of physical strength, affecting work speed; existing automated cigarette loading equipment can only transport the cigarette clips to a specified floor height, and cannot achieve a tight arrangement of the cigarette clips, resulting in poor loading effect; moreover, most equipment is difficult to adapt to unpaved ground, or cannot be flexibly adjusted to meet the loading and unloading needs of different heights of 2-4 floors.

[0003] Therefore, there is an urgent need for an intelligent device that can adapt to complex ground environments, balance safety and efficiency, and accurately adapt to multi-level loading and unloading heights to solve the pain points of traditional operations. Utility Model Content

[0004] To address the problems of traditional tobacco leaf loading and unloading relying on manual ladder erection, which poses a risk of tipping over, frequent ladder relocation leading to low efficiency, existing equipment being difficult to adapt to unpaved ground, unable to accurately adapt to multi-level heights, resulting in loose tobacco loading, low loading efficiency, poor uniformity, difficulty in controlling the tightness of the loading, and high labor intensity of manual lifting, this utility model provides a self-propelled intelligent tobacco leaf loading and unloading device for tobacco curing barns, which can overcome these problems and achieve safe and efficient loading and unloading.

[0005] The solution adopted by this utility model to solve its technical problem is: a self-propelled intelligent tobacco loading and unloading equipment for tobacco curing barns, including a modular track and a self-propelled mobile platform. The modular track is laid on the floor of the tobacco curing barn. The self-propelled mobile platform is slidably mounted on the modular track and moves forward in the tobacco curing barn along the path of the modular track. A support frame is provided on the bottom platform plate of the self-propelled mobile platform. A personnel standing platform is provided above the support frame. An automatic lifting mechanism is provided below the personnel standing platform. The automatic lifting mechanism controls the raising and lowering of the personnel standing platform to adjust its height. A tobacco clip or tobacco rod conveying mechanism is provided on one side of the personnel standing platform on the self-propelled mobile platform. The tobacco clip or tobacco rod conveying mechanism includes two sets of synchronous belt slides vertically mounted on the self-propelled mobile platform. The two sets of synchronous belt slides are arranged in parallel and have a height difference. Tobacco clips or tobacco rod clamps are slidably mounted on the synchronous belt slides. The bearing surface height of the two sets of tobacco clips or tobacco rod clamps is the same. A drive mechanism for controlling the operation of the synchronous belt slides is provided on the self-propelled mobile platform.

[0006] Furthermore, the automatic lifting mechanism includes a base plate and a top plate arranged vertically. The base plate is fixed above the support frame, and the top plate is fixed below the personnel standing platform. A scissor fork is provided between the base plate and the top plate. One side of the scissor fork is hinged to the base plate and the top plate at its upper and lower ends. The base plate and the top plate have horizontal straight grooves. The other side of the scissor fork is slidably fitted into the straight grooves through pins at its upper and lower ends. Connecting rods are respectively installed at the upper and lower ends of the scissor fork, and the two connecting rods are connected by an electric push rod.

[0007] Furthermore, the modular track consists of a walking guide rail and an intermediate connecting frame. The two walking guide rails are arranged in parallel, and the ends of the walking guide rails are spliced ​​together by the intermediate connecting frame.

[0008] Furthermore, the drive mechanism includes a tobacco leaf lifting motor mounted on a self-propelled mobile platform. The output end of the tobacco leaf lifting motor is connected to the synchronous pulley in one of the sets of synchronous belt slides. A drive shaft is horizontally connected between the synchronous pulleys of the two sets of synchronous belt slides, and the synchronous operation of the two sets of synchronous belt slides is realized through the drive shaft.

[0009] Furthermore, the self-propelled mobile platform includes a platform plate, a drive axle, and wheels. The drive axle is provided at the lower left and right ends of the platform plate, and wheels are installed at both ends of the drive axle. The wheels are rotatably connected to the guide rail. The front end of the guide rail is connected to an overlapping rail, and the lower part of the guide rail is equipped with height adjustment supports arranged by supporting steel rails.

[0010] Furthermore, a vertical pole is fixed to the self-propelled mobile platform near the synchronous belt slide, and the synchronous belt slide is fixed to the pole by a fixing plate. One side of the pole is connected and fixed to the support frame by a steel frame.

[0011] Furthermore, a sliding sleeve is vertically installed between the platform plate and the personnel standing platform, and the sliding sleeve is located on one side of the straight groove of the automatic lifting mechanism.

[0012] Furthermore, guardrails are installed on the standing platform, support frame, and uprights.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model adopts a modular track design, which, through the modular splicing of the walking guide rail and the intermediate connecting frame, can quickly adapt to tobacco curing barns of different lengths, including unhardened tobacco curing barns, solving the problem of ground flatness. The track is detachable and reusable, allowing for flexible transfer between multiple tobacco curing barns, improving equipment turnover rate, and achieving "install and use immediately, disassemble after use" functionality. The self-propelled mobile platform moves smoothly along the track, replacing traditional ladders, avoiding the risk of ladder tilting, and ensuring platform stability. The automatic lifting mechanism uses a scissor-type structure to drive the personnel standing platform to lift and lower, precisely adapting to 2-4 layer working heights, reducing the force consumption of manually lifting the tobacco clamps. The scissor structure ensures a stable center of gravity during lifting and lowering, guaranteeing safety for working at heights. The tobacco clamp or tobacco rod conveying mechanism uses two sets of synchronous belt slides, achieving synchronous drive through the transmission shaft, ensuring horizontal lifting and lowering of the tobacco clamps, adapting to the needs of multi-layer rapid loading and unloading. The opening of the tobacco clamp or tobacco rod clamp can be infinitely adjusted, compatible with mainstream tobacco clamps and bamboo poles for hanging tobacco. Workers can directly and tightly arrange the tobacco clamps on the standing platform, solving the problems of loose and uneven tobacco loading and low work efficiency in existing equipment.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1-7 This utility model provides a technical solution for a self-propelled intelligent tobacco loading and unloading equipment for tobacco curing barns: Example

[0025] like Figure 1 , Figure 2 As shown, this self-propelled intelligent tobacco loading and unloading equipment for tobacco curing barns adopts a modular design, mainly composed of two core parts: a modular track 1 and a self-propelled mobile platform 2. It is supplemented by components such as a support frame 3, a personnel standing platform 4, an automatic lifting mechanism 5, a tobacco clamp or tobacco stem conveying mechanism 6, and tobacco clamp or tobacco stem clamps 7, forming a complete tobacco loading and unloading system. The modular track 1 serves as the equipment's moving reference and is laid flat on the floor of the tobacco curing barn. The self-propelled mobile platform 2 straddles the modular track 1 via four wheels 23 at its bottom, allowing it to move precisely along the path of the modular track 1 within the tobacco curing barn. The support frame 3 is fixed to the platform plate 21 of the self-propelled mobile platform 2. The personnel standing platform 4 is connected above the support frame 3 via the automatic lifting mechanism 5, enabling adjustment of the personnel's working height. The tobacco clamp or tobacco stem conveying mechanism 6 is located inside the personnel standing platform 4 and is fixed to the self-propelled mobile platform 2 via uprights 61. It is used to drive the tobacco clamp or tobacco stem clamps 7 to rise and fall, completing the conveying and loading / unloading of tobacco leaves.

[0026] Specifically, such as Figure 2As shown, the modular track 1 adopts a modular splicing design, consisting of two parallel walking guide rails 11 and several intermediate connecting frames 12. The walking guide rails 11 are made of high-strength metal round tubes (other shapes of rails can also be used). The spacing between the two walking guide rails 11 is fixed by the intermediate connecting frames 12, and the beginning and end ends of the walking guide rails 11 can be detachably spliced ​​through the intermediate connecting frames 12. This allows for flexible adjustment of the total track length according to the length of the tobacco curing barn, adapting to tobacco curing barns of different lengths. Furthermore, it can be reused among multiple tobacco curing barns, achieving "install and use immediately, disassemble after use." This solves the flatness problem caused by the unhardened ground of the tobacco curing barn and improves the turnover rate of the equipment among multiple curing barns.

[0027] The bottom of the self-propelled mobile platform 2 is a load-bearing platform plate 21, with drive axles 22 symmetrically installed at the lower left and right ends. Each end of the drive axle 22 is equipped with a traveling wheel 23, which rolls in conjunction with the traveling guide rail 11. The reduction motor inside the drive axle 22 outputs torque, which drives the traveling wheel 23 to roll along the traveling guide rail 11, thus moving the entire platform. This allows the self-propelled mobile platform 2 to move smoothly forward or backward along the assembled track 1 without manual handling or position adjustment, solving the problem of frequent ladder movement in traditional operations. The traveling wheel 23 uses rubber-coated wheels, increasing friction, reducing noise, and adapting to slight bumps and potholes to avoid jamming. The cooperation between the track and the traveling wheel 23 prevents slippage and offset, ensuring platform stability during loading and unloading and improving operational safety.

[0028] The self-propelled mobile platform 2 has a portal frame 3 fixed to the platform plate 21 by bolts. An automatic lifting mechanism 5 is installed above the support frame 3. The personnel standing platform 4 provides standing space for the workers. It is connected to the support frame 3 below by the automatic lifting mechanism 5. The height of the personnel standing platform 4 can be controlled by the automatic lifting mechanism 5 to adjust the working height of the workers.

[0029] according to Figure 3 and Figure 4As shown, the tobacco clamp or tobacco stem conveying mechanism 6 provides power for the vertical conveying of tobacco leaves. Its core structure includes: two sets of synchronous belt slides 63 arranged on the left and right sides inside the personnel standing platform 4. The synchronous belt slides 63 are longitudinally set on the self-propelled mobile platform 2, and tobacco clamps or tobacco stem clamps 7 are slidably mounted on them, forming the tobacco clamp or tobacco stem conveying mechanism 6, which is used to drive the tobacco clamps or tobacco stem clamps 7 to rise and fall, completing the conveying and unloading of tobacco leaves. Two uprights 61 are vertically fixed on the self-propelled mobile platform 2. The synchronous belt slides 63 are locked to the uprights 61 by fixing plates 62. The root of one of the uprights 61 is further reinforced to the support frame 3 by a steel frame 64, forming a double rigid support to prevent the slide from shaking during long-stroke lifting. The drive mechanism consists of a tobacco leaf lifting motor 65 and a drive shaft 66. The tobacco leaf lifting motor 65 is mounted on the self-propelled mobile platform 2. The output end of the tobacco leaf lifting motor 65 is connected to the synchronous pulleys within any set of synchronous belt slides 63. A drive shaft 66 connects the synchronous pulleys of the two sets of synchronous belt slides 63, enabling transmission between the synchronous pulleys. The tobacco leaf lifting motor 65 drives the synchronous pulleys to rotate, which in turn drives the synchronous pulleys of the two sets of synchronous belt slides 63 to rotate synchronously via the drive shaft 66. This causes the synchronous belt to vertically lift and lower the tobacco clips or tobacco stalk clamps 7 along the slides, achieving high-level transport of the tobacco clips. The output torque of the tobacco leaf lifting motor 65 is synchronously distributed to the left and right synchronous pulleys via the drive shaft 66, ensuring that the linear velocity difference between the two sets of synchronous belt slides 63 is less than 0.5%. This ensures that the tobacco clips or tobacco stalk clamps 7 remain horizontal during lifting or lowering, preventing the tobacco leaves from slipping due to tilting. The synchronous belt uses a high-strength steel wire core polyurethane belt with a tensile strength greater than 1500N. It can complete a 1m single-pass lifting and lowering within 3s, meeting the requirements of rapid tobacco loading on the second, third, and fourth floors of the tobacco curing barn.

[0030] To facilitate quick removal of the tobacco leaves from the tobacco clips or tobacco stem clamps 7 after lifting, such as... Figure 2 and Figure 3 As shown, the height difference between the two synchronous belt slides 63 can be set, that is, the height of one synchronous belt slide 63 is lower than that of the other side, and the maximum lifting height of the lower synchronous belt slide is consistent with the height of the third layer of the tobacco curing barn. After the tobacco clips or tobacco rod clamps 7 mounted on the lower synchronous belt slide 63 are lifted, their bearing surface is located above the top of the synchronous belt slide. With this setting, when the tobacco leaves are lifted to the designated height, one end will not be blocked by the synchronous belt slide 63, thus making it easy to remove the tobacco clips or tobacco rods from the clamps. When lifting the tobacco leaves, the tobacco loading and lifting operations of the second, third and fourth layers of the tobacco curing barn are all carried out by the tobacco clip or tobacco rod conveying mechanism 6 to lift the tobacco leaves to the height of the third layer, that is, the top of the lower synchronous belt slide 63. When loading the second and fourth layers, the tobacco leaf hanging work can be completed simply by bending over or raising the arm.

[0031] The cigarette clip or cigarette holder 7 is connected to the slider inside the synchronous belt slide table 63 via a quick-release pin. The clamp opening can be steplessly adjusted between three settings: 1320mm, 1340mm, and 1360mm, compatible with mainstream cigarette clip specifications. Additionally, a rubber pad is added to the inside of the cigarette clip or cigarette holder 7 to increase friction and prevent scratches on the paint layer of the cigarette clip. For areas where bamboo poles are still used to hang cigarettes, simply adjusting the clamp opening to the maximum of 1400mm allows for direct clamping of bamboo poles, expanding the applicability of the equipment.

[0032] Detachable guardrails 8 can be installed at appropriate locations on the personnel standing platform 4, support frame 3, and uprights 61 to provide protection for high-altitude operations. LED lights can also be installed at the front and rear ends of the self-propelled mobile platform 2 to provide ≥300 lx of illumination in the enclosed and dimly lit tobacco curing barn, reducing the risk of misoperation. In addition, the self-propelled mobile platform 2, automatic lifting mechanism 5, and tobacco clamp or tobacco rod conveying mechanism 6 are all equipped with wireless remote control, allowing operators to control the platform's forward and backward movement and the lifting and lowering of the tobacco clamps from the ground, avoiding frequent climbing up and down.

[0033] In practical use, this utility model of a self-propelled intelligent tobacco loading and unloading device for tobacco curing barns first involves modularly assembling the walking guide rail 11 according to the length of the curing barn via an intermediate connecting frame 12, forming a track path adapted to the length of the curing barn. The walking wheels 23 of the self-propelled mobile platform 2 straddle the assembled track 1, with the wheels 23 rolling in coordination with the walking guide rail 11. The reduction motor within the drive axle 22 provides power, driving the wheels 23 to roll along the track, allowing the self-propelled mobile platform 2 to move autonomously within the curing barn. Next, the operator stands on the personnel standing platform 4, and the device is automatically lifted... Mechanism 5 adjusts the working height to allow operators to adapt to the current working height, reducing the effort required to lift the tobacco clamps. Then, the operators below place the tobacco clamps filled with tobacco leaves into the tobacco clamps or tobacco rod clamps 7 and clamp them. The tobacco leaf lifting motor 65 starts and drives two sets of parallel synchronous belt slides 63 through the transmission shaft 66, causing the tobacco clamps or tobacco rod clamps 7 to rise and fall vertically along the slides, transporting the tobacco clamps to the current working height. Finally, the operators on the personnel standing platform 4 directly remove the tobacco clamps transported to the current level and arrange them tightly on the tobacco rack in the tobacco curing room without lifting them under load.

[0034] After loading and unloading 3-4 tobacco clips at the current position, the self-propelled mobile platform 2 is started via wireless remote control or platform control panel. The drive axle 22 drives the traveling wheels 23 to smoothly retreat along the traveling guide rail 11, moving to the next row of tobacco hanging positions to continue the tobacco hanging work. Repeat the above steps, adjusting the height of the personnel standing platform 4 via the automatic lifting mechanism 5 to adapt to the different heights of 2-4 layers. The tobacco clip or tobacco rod conveying mechanism 6 simultaneously adjusts the conveying height to complete the loading and unloading of tobacco leaves at each layer. Example

[0035] Based on Embodiment 1, this embodiment further explains the structure of the automatic lifting mechanism 5.

[0036] The specific structure of the automatic lifting mechanism 5 is as follows: Figure 5 As shown, it mainly consists of a base plate 51, a top plate 52, and a scissor lift 53. The base plate 51 and top plate 52 are arranged parallel to each other vertically, with the base plate 51 fixed to the support frame 3 and the top plate 52 fixed below the personnel standing platform 4. Symmetrical vertical grooves 54 are formed on the base plate 51 and top plate 52. One side of the scissor lift 53 is hinged to the top plate 52 and base plate 51 at its upper and lower ends, while the other side slides within the vertical groove 54 via a pin 55, forming a classic scissor-type structure. Connecting rods 56 are fixedly connected to the pins 55 at the upper left and lower right ends of the scissor lift 53, respectively. The two ends of an electric push rod 57 are hinged to the upper and lower connecting rods 56, respectively. The extension and retraction of the electric push rod 57 drives the scissor lift 53 to open and close, realizing the vertical lifting and lowering of the top plate 52 and the personnel standing platform 4. The system precisely adjusts the standing height to accommodate the loading and unloading needs of 2-4 layers of tobacco leaves, reducing the strength required for operators to lift the tobacco clamps and solving the problem of muscle fatigue in traditional high-altitude operations. Because the center of gravity of the scissor mechanism is always located on the center line of the support frame 3 during the deployment process, it has high anti-overturning stability. Furthermore, a sliding sleeve 9 is vertically installed between the platform plate 21 and the personnel standing platform 4. The sliding sleeve 9 is located on one side of the straight groove 54 of the scissor in the automatic lifting mechanism 5. By designing two limiting sliding sleeves 9 on one side of the scissor 53, the amount of swaying of the standing surface at high stroke can be reduced, increasing the stability of the lifting plane. The amount of platform sway at high stroke can be controlled within ±3mm, ensuring that the operator still feels stable at the highest working position of 3.4m.

[0037] The core function of the automatic lifting mechanism 5 provided by this utility model is to drive the personnel standing platform to adjust its height to accommodate the loading and unloading needs of 2-4 layers of cigarette clips. The scissor-type structure used in the embodiment is only one specific implementation method to achieve this function, and is not a limitation of this utility model. Other lifting mechanisms known in the prior art, such as the in-line lifting structure driven by the hydraulic lifting cylinder, the lifting structure driven by the screw and nut, and the lifting structure with gear and rack, etc., as long as they can meet the lifting stroke, load-bearing capacity, and stability requirements of the personnel standing platform 4, all fall within the protection scope of this utility model. Example

[0038] Since traditional smoke rooms have steps or ramps at the entrance, which affects the movement of equipment, this embodiment further designs and improves the modular track 1 to solve this problem.

[0039] like Figure 7As shown, a supporting rail 13 is correspondingly installed below the walking guide rail 11 of the assembled track 1. The walking guide rail 11 is mounted on the supporting rail 13. Multiple vertical height-adjustable supports 14 are arranged on the fixing ears on both sides of the supporting rail 13. The height-adjustable supports 14 support the supporting rail 13 and the walking guide rail 11. The support height is adjusted by the height-adjusting nuts 15 on the height-adjusting supports 13, so that the height of the walking guide rail 11 is level with the ground level of the tobacco room entrance. At the front entrance of the assembled track 1, an overlapping rail 16 is also assembled and connected. The overlapping rail 16 is set as a ramp structure. The ramp angle is reasonably designed according to the height of the steps outside the tobacco room, which can smoothly transition the height difference between the ground outside the tobacco room and the walking guide rail 11, eliminating steps or steep slopes, so that the equipment can be pushed forward smoothly and effortlessly. In addition, the flat assembled track can extend 2m outside the tobacco room door. When the equipment is driven out of the door, tobacco leaves can be hung in the space above the door, improving the space utilization of the tobacco room.

[0040] The above description is only a preferred embodiment of the present utility model and does not limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
