Description

Technical Field

[0001] This invention relates to the field of tobacco curing equipment technology, and in particular to an automatic tobacco loading device and a tobacco curing barn. Background Technology

[0002] Flue-cured tobacco is an important economic crop, and currently, intensive curing barns are widely used for tobacco curing in China. After the tobacco leaves are harvested and bundled, large quantities of tobacco bundles loaded with fresh leaves need to be transferred and hung on multi-layered racks inside the curing barn. Currently, most tobacco-growing areas still rely on manual labor for loading: workers carry the tobacco bundles back and forth, and climb to high places to hang them, resulting in high labor intensity, low efficiency, and safety hazards from falls. Labor shortages and continuously rising labor costs during the peak tobacco harvesting season constrain the development of large-scale tobacco cultivation.

[0003] In existing technologies, tobacco loading lifting devices have emerged, but most are independent mobile devices with only simple lifting functions. During operation, multiple people are still needed to deliver the tobacco bundles, resulting in a low level of automation. This type of device is an independent structure from the tobacco curing barn, requiring repeated alignment and calibration for each operation. The positioning accuracy is poor, which can easily lead to problems such as misaligned tobacco bundles and tobacco leaf compression and accumulation, causing poor airflow inside the curing barn and affecting the uniformity of curing.

[0004] Meanwhile, the tobacco racks inside traditional tobacco curing barns are fixed structures, only suitable for manual loading operations, and cannot be integrated with automated tobacco loading devices. Adding automated equipment often requires modifications to the walls and floor of the curing barn, resulting in high costs that are unacceptable to most tobacco farmers. Some integrated equipment is also bulky, occupying a significant portion of the curing barn's internal space after loading, interfering with hot air circulation, and negatively impacting the tobacco curing effect.

[0005] Therefore, how to provide a coordinated and complementary automatic tobacco loading equipment and tobacco curing barn to realize automated tobacco loading operations and reduce labor requirements is a technical problem that those skilled in the art continue to solve.

Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0023] In the description of the embodiments of the present invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] The following is combined with Figures 1-3 The automatic tobacco loading equipment of the present invention includes a tobacco curing barn body, a feeding and conveying mechanism, a vertical lifting mechanism, and a tobacco carrying platform conveying mechanism.

[0025] The tobacco curing barn is equipped with a multi-layer tobacco-carrying platform conveyor mechanism 15 inside. The feeding conveyor mechanism is located on the outside of the tobacco curing barn and is used to carry the tobacco bundles loaded with fresh tobacco leaves and to complete the outward transfer and conveying of the tobacco bundles.

[0026] The vertical lifting mechanism is installed at the entrance of the tobacco curing barn. The input end of the vertical lifting mechanism is connected to the feeding conveyor mechanism, and the output end of the vertical lifting mechanism can be connected to the conveying mechanism 15 of each layer of the tobacco curing barn.

[0027] The tobacco conveying mechanism 15 can receive tobacco bundles sent out by the vertical lifting mechanism and continue to transport the received tobacco bundles to the predetermined placement position inside the tobacco curing barn.

[0028] In an embodiment of the present invention, the feeding and conveying mechanism completes the feeding and conveying of tobacco bundles outside the curing barn. The vertical lifting mechanism switches heights and connects with the tobacco bundle conveying mechanism 15 of each layer one by one. Then, the internal tobacco bundle conveying mechanism 15 sends the tobacco bundles into the curing barn. The whole mechanism realizes the continuous and automated loading operation of tobacco bundles by external feeding, height switching, and layered delivery into the curing barn, replacing manual handling and hanging tobacco at heights, reducing the number of on-site workers, and eliminating the safety hazard of falling from heights. The layered connection structure ensures that the tobacco bundles can be positioned in layers, avoiding the squeezing and stacking of tobacco leaves, and ensuring unobstructed airflow inside the curing barn.

[0029] Moreover, once the tobacco is loaded, the equipment can be stored away to avoid taking up baking space, ensuring normal circulation of hot air in the curing room and meeting the needs of large-scale, standardized continuous tobacco curing production.

[0030] In a specific embodiment of the present invention, the feeding and conveying mechanism includes an operating table 1, a control device 2, a conveying bracket 3, a belt conveying assembly, and a first driving component 7.

[0031] The control device 2 is mounted on the operating platform, allowing operators to place and load the tobacco bundles. The conveyor support 3 is connected to the operating platform. The belt conveyor assembly is installed on the conveyor support 3. The first drive component 7 is connected to the belt conveyor assembly, providing it with conveying power.

[0032] In this embodiment, the operating platform 1 provides a ground-level material loading station for the tobacco bundles, and the operator only needs to place the tobacco bundles on the ground without having to climb to a height.

[0033] The control device 2 centrally controls the operation of the whole machine; the conveyor bracket 3 serves as the mounting base for the belt conveyor assembly, and the first drive component 7 provides power to stably convey the tobacco bundle on the operating table 1 to the input end of the vertical lifting mechanism, thereby realizing the smooth transfer and conveying of the tobacco bundle.

[0034] See Figure 3 As shown, the belt conveyor assembly includes a first driving pulley 4, a driven pulley 5, and a belt. The first driving pulley 4 is connected to the first driving member 7 for transmission. The driven pulley 5 and the first driving pulley 4 together form a belt drive pulley, and the belt is wrapped around the outer circumference of the belt drive pulley. The first driving member 7 outputs power to drive the first driving pulley 4 to rotate, which in turn drives the belt to circulate, and the belt lifts and carries the tobacco bundle to complete the conveying.

[0035] In the above embodiments, a belt is used to transport the tobacco bundles. The belt flexibly contacts the tobacco bundles, minimizing damage to the tobacco bundles and leaves during transport. The belt drive, consisting of the first driving wheel 4 and the driven wheel 5, ensures smooth operation, stable load transport, and reliable transport of the tobacco bundles towards the vertical lifting mechanism.

[0036] In a specific embodiment of the present invention, the belt conveyor assembly further includes a guide wheel 6, which is arranged on the inner side of the belt. The guide wheel 6 can limit and constrain the tobacco carrier from the side, prevent the tobacco carrier from deviating laterally on the conveying path, and reduce the approach angle in the positive direction, so as to make smooth docking during the conveying process.

[0037] In the above embodiments, the guide wheel 6 provides lateral limiting constraint on the tobacco bundle during the conveying process, corrects the posture of the tobacco bundle, prevents the tobacco bundle from deviating during conveying, prevents the tobacco leaves from being squeezed and piled up during subsequent docking and loading, and ensures accurate docking position with the vertical lifting mechanism.

[0038] In a specific embodiment of the present invention, the vertical lifting mechanism includes a slide bar 13, a ball screw, a lifting slider 10, and a second driving member 9.

[0039] The slide rod 13 and the ball screw are arranged vertically side by side at the entrance of the tobacco curing barn. The lifting slider 10 is slidably mounted on the slide rod 13, and the lifting slider 10 and the ball screw form a threaded transmission engagement. The second driving component 9 is used to drive the ball screw to rotate, and the rotation of the ball screw in turn drives the lifting slider 10 to move vertically up and down along the slide rod 13.

[0040] In the above embodiments, the slide bar 13 provides a sliding guide for the lifting slider 10. The ball screw drive has high positioning accuracy and mechanical self-locking capability, preventing the lifting slider 10 and the tobacco carrier from falling accidentally in the event of a power outage, thus ensuring high operational safety. Driven by the second drive component 9, the lifting slider 10 can switch between different heights, achieving precise alignment between the docking conveyor and the tobacco carrier conveying mechanism 15 of each layer inside the curing barn. This eliminates the need for repeated manual height calibration, improving the efficiency of tobacco loading operations.

[0041] In a specific embodiment of the present invention, each layer of tobacco carrying platform conveying mechanism 15 is provided with a third driving member 12 and a second driving wheel 14. The third driving member 12 outputs power to drive the second driving wheel 14 to rotate. The second driving wheel 14 drives the tobacco carrying platform conveying mechanism 15 to run, thereby conveying the received tobacco carrying platform to the interior of the tobacco curing barn body.

[0042] In the above embodiments, each layer of the tobacco carrier conveying mechanism 15 is equipped with an independent third drive component 12 and a second drive wheel 14. Each layer can start and stop conveying independently. After receiving the tobacco carrier from the vertical lifting mechanism, it will autonomously convey the tobacco carrier into place without manual pushing and transfer, realizing independent conveying operation of each layer, ensuring that the tobacco carrier is placed in a uniform position, which is conducive to the uniform circulation of hot air in the curing room.

[0043] In a specific embodiment of the present invention, the first driving component 7, the second driving component 9, and the third driving component 12 are all stepper motors. The first driving component 7, the second driving component 9, and the third driving component 12 are all electrically connected to the control device 2, and the control device 2 outputs control signals to control the start, stop, speed, and travel of multiple stepper motors.

[0044] In the above embodiments, the stepper motor has high control precision and can realize layer height memory and fixed-point start / stop functions, making it easy to preset the operation parameters of each layer. All driving components are centrally electrically controlled by the control device 2, and the actions are coordinated and controllable, simplifying equipment operation. Ordinary tobacco farmers can quickly get started and realize the completion of the entire tobacco setting operation by a single person.

[0045] In a specific embodiment of the present invention, an anti-collision sensor is also included. The anti-collision sensor is electrically connected to the control device 2. The anti-collision sensor is used to detect obstacles on the running path of the equipment in real time. When the main component of the tobacco curing barn or other obstacles are detected, a feedback signal is sent to the control device 2. The control device 2 can control the equipment to stop running in time to avoid collision and scratches between the equipment and the main component of the tobacco curing barn.

[0046] In the above embodiments, anti-collision sensors are added to monitor obstacles in real time during the lifting and conveying of the equipment, thereby avoiding equipment damage and structural damage caused by the equipment colliding with the curing oven components and improving the safety performance of the equipment operation.

[0047] In a specific embodiment of the present invention, the tobacco conveying mechanism 15 and the tobacco curing barn are assembled and fixed by a detachable connection.

[0048] In the above embodiments, the Yantai conveying mechanism 15 is detachable and can be pre-installed in the production stage of newly built tobacco curing barns, or it can be modularly added and modified directly to existing old dense curing barns. It does not require large-scale damage to the curing barn floor and main wall structure, reducing the difficulty and cost of renovation and making it easier to promote and apply in grassroots tobacco areas.

[0049] The complete working process of the automatic tobacco loading equipment provided by this invention is as follows: The operator places the tobacco bundles loaded with tobacco leaves on the operating table 1 and sets the working height parameters for each layer through the control device 2. The second drive component 9 drives the ball screw to raise and lower the lifting slider 10 to the target layer height. The first drive component 7 drives the belt conveyor assembly to transport the tobacco bundles to the docking conveyor section of the lifting slider 10. The tobacco bundles are sent into the tobacco-bearing platform conveyor mechanism 15 of that layer via the docking conveyor section. The third drive component 12 drives the second drive wheel 14 to drive the tobacco-bearing platform conveyor mechanism 15 to move and transport the tobacco bundles to the predetermined position inside the curing barn. After one layer is filled, the vertical lifting mechanism switches its height to complete the loading of the remaining tobacco bundles in sequence. After the entire barn is filled, the outer feeding conveyor mechanism and the vertical lifting mechanism can be moved out of the curing barn entrance, without occupying the curing air duct of the curing barn or interfering with the curing hot air circulation.

[0050] A second aspect of the present invention also provides a tobacco curing barn, including the automatic tobacco loading equipment as described in any of the preceding embodiments.
