Description

Technical Field

[0001] This application relates to the field of tobacco leaf maintenance, and in particular to a device for conveying medicine boxes above tobacco stacks. Background Technology

[0002] After new tobacco leaves are transported to the tobacco warehouse in large quantities, they need to undergo a curing phase. During this curing phase, an oxygen-deprivation pest control method is used. Specifically, this involves creating a low-oxygen or anaerobic environment, causing pests to die from lack of oxygen. Therefore, after stacking the tobacco boxes, curing personnel need to place an oxygen-depriving agent on top of the stack. The agent is stored in boxes made of plastic or similar materials, and the quantity varies from a dozen to thirty boxes depending on the size of the stack. During operation, the oxygen-depriving agent boxes need to be moved to the top of the tobacco box stack and evenly distributed to all corners of the stack.

[0003] Currently, due to limited height in storage areas, tobacco stacks are typically piled high, very close to the top, to maximize space utilization. For example, tobacco storage warehouses are approximately 4.2 meters high, and some have air conditioning or fire ducts, resulting in the bottom edge of the air conditioning ducts being only 70-80 centimeters from the top of the tobacco boxes. Therefore, after the stacks are piled, operators must crawl while carrying the deoxygenating agent boxes to avoid hitting the air conditioning ducts, fire extinguishers, or lighting fixtures on the top of the warehouse. This often takes a considerable amount of time, leading to low efficiency and increasing the risk of injury to maintenance personnel from contact with air conditioning ducts, fire extinguishers, or lighting fixtures.

[0004] In addition, during the period of large-scale storage of new tobacco, there is a shortage of personnel, and traditional pallet sealing operations are not conducive to improving the efficiency of pallet sealing operations, and there are significant safety hazards and operational difficulties. Utility Model Content

[0005] Therefore, it is necessary to provide a medicine box conveying device above the tobacco stack.

[0006] One embodiment of this application is a medicine box conveying device above a tobacco stack, which includes a roller conveyor, a drum and a height support frame;

[0007] The roller conveyor has a first end and a second end;

[0008] The height support frame is connected to the roller conveyor at the first end, and the height support frame is located below the roller conveyor so that the first end is higher than the second end;

[0009] The height support frame and the roller conveyor are configured to be located above the tobacco stack, and the rollers are evenly arranged on the roller conveyor;

[0010] The roller conveyor is used to carry medicine boxes. When the height support frame is in a supported state, the medicine box located at the first end moves to the second end under the action of gravity and the rolling action of the roller.

[0011] The aforementioned medicine box conveying device above the tobacco stack cleverly forms an automatic conveying channel in the limited space above the tobacco stack through the design of matching rollers, drums, and height support frames. Moreover, it requires no energy; it utilizes the gravity potential energy of the medicine boxes themselves, combined with the rolling of the drums, to transport the medicine boxes along the rollers to the preset position. This avoids the trouble of operators carrying medicine boxes above the tobacco stack, effectively protects operators working above the tobacco stack, greatly reduces safety hazards and operational difficulty, and significantly improves work efficiency. It also has the advantage of being easy to carry, thus facilitating its widespread use.

[0012] In some embodiments, the medicine box conveying device above the tobacco stack has a limit pin hole on the roller conveyor, the limit pin hole being used to insert a limiter to limit the extreme position of the medicine box movement on the roller conveyor.

[0013] In some embodiments, the medicine box conveying device above the tobacco stack also includes the limiter.

[0014] In some embodiments, the limiter includes a vertical rod detachably inserted into the limit pin hole and a horizontal rod blocking the medicine box, wherein the vertical rod and the horizontal rod are arranged perpendicularly to each other.

[0015] In some embodiments, the rollers are arranged in an array on the roller conveyor.

[0016] In some embodiments, the height support frame is a foldable support frame, one end of which is rotatably connected to the roller conveyor at the first end; or...

[0017] The height support frame is H-shaped or U-shaped.

[0020] The operating lever is connected to the height support frame or to the roller conveyor at the first end, and the operating lever is connected to the push block through the transmission member, for applying force to the medicine box located at the second end through the push block, so that the medicine box leaves the roller conveyor.

[0021] In some embodiments, the remote pushing component further includes a resilient reset member connected to the roller conveyor at the second end;

[0022] The push block is disposed on the elastic reset member. The push block is used to overcome the force of the elastic reset member under the action of the transmission member, move away from the first end to push the medicine box at the second end; and reset under the action of the elastic reset member when the transmission member is not exerting force.

[0023] In some embodiments, the medicine box conveying device above the tobacco stack further includes an extension plate and a height stop on the extension plate;

[0024] The extension plates are respectively connected to both sides of the roller conveyor, and the height stop is used to block the medicine box on both sides of the roller conveyor to prevent the medicine box from leaving the roller conveyor on both sides.

[0025] In some embodiments, the height of the height stop is 30% to 60% of the height of the medicine box; or,

[0026] The height stop is a flexible cylindrical rod. Attached Figure Description

[0045] This application discloses a medicine box conveying device above a tobacco stack, which includes some or all of the technical features of the following embodiments; that is, the medicine box conveying device above a tobacco stack includes some or all of the following structures. In one embodiment of this application, a medicine box conveying device above a tobacco stack includes a roller conveyor, rollers, and a height support frame; the roller conveyor has a first end and a second end; the height support frame is connected to the roller conveyor at the first end, and the height support frame is located below the roller conveyor, so that the first end is higher than the second end; the height support frame and the roller conveyor are configured to be disposed above the tobacco stack, and the rollers are evenly disposed on the roller conveyor; the roller conveyor is used to carry medicine boxes, and when the height support frame is in a supported state, the medicine box located at the first end moves to the second end under the action of gravity and the rolling action of the rollers. The aforementioned medicine box conveying device above the tobacco stack cleverly creates an automatic conveying channel within the limited space above the tobacco stack through a designed and coordinated roller conveyor, drums, and height support frame. Moreover, it requires no energy; utilizing the medicine boxes' own gravitational potential energy in conjunction with the drums' rotation, the medicine boxes are conveyed along the roller conveyor to a preset position. This eliminates the inconvenience of operators manually handling medicine boxes above the tobacco stack, effectively protecting workers on the job, significantly reducing safety hazards and operational difficulty, greatly improving work efficiency, and offering the advantage of portability, thus facilitating widespread adoption. The following section will combine... Figures 1 to 11 The medicine box conveying device above the tobacco stack is described in detail.

[0046] In some embodiments, a medicine box conveying device 100 above a tobacco stack is described as follows: Figure 1 As shown, it includes a roller conveyor 110, rollers 120, and a height support frame 130. The rollers 120 are evenly arranged on the roller conveyor 110. The roller conveyor 110 has a first end 111 and a second end 112. Figure 2 The height support frame 130 is connected to the roller conveyor 110 at the first end 111, and the height support frame 130 is located below the roller conveyor 110, so that the first end 111 is higher than the second end 112; combined with Figure 3 and Figure 4 The medicine box conveying device 100 above the tobacco stack is applied above the tobacco stack 200 and combined with... Figure 5 and Figure 6The height support frame 130 and the roller conveyor 110 are configured to be positioned above the tobacco stack 200. The roller conveyor 110 carries the medicine box 300. When the height support frame 130 is in a supported state, the medicine box 300 located at the first end 111 moves to the second end 112 under the action of gravity and the rolling action of the roller 120. This structural design, through the design of the matching roller conveyor 110, roller 120, and height support frame 130, cleverly forms an automatic conveying channel in the limited space above the tobacco stack. Moreover, it requires no energy; by utilizing the gravitational potential energy of the medicine box 300 in conjunction with the rolling action of the roller 120, the medicine box 300 can be conveyed to the preset position along the roller conveyor 110. This avoids the trouble of operators carrying the medicine box 300 above the tobacco stack, effectively protects the operators working above the tobacco stack, greatly reduces safety hazards and operational difficulty, and greatly improves work efficiency. It also has the advantage of being easy to carry, thus facilitating its widespread use.

[0047] In each embodiment, such as Figure 2 As shown, the roller conveyor 110 has a first end 111 and a second end 112; as an example, the roller conveyor 110 forms a straight conveying path, with the first end 111 as the starting point and the second end 112 as the ending point. In specific applications, the medicine box conveying device 100 above the tobacco stack can be used by one person or two people. When used by two people, as follows... Figure 6 As shown, the first person is positioned at the first end 111, and the second person is positioned above the tobacco stack 200. The second person adjusts their relative distance to the second end 112 according to the progress of the work. Single-person operation is another innovation of the medicine box conveying device 100 above the tobacco stack, which can be used in conjunction with the position adjustment of the roller conveyor 110 or with the remote pushing component 160, as described below. Figure 10 As shown, without the need for colleagues to climb onto the top of the smokestack 200, one person can complete the placement of the medicine boxes 300 through the medicine box conveying device 100 above the smokestack. This greatly saves human resources, reduces personnel configuration requirements, lowers labor costs, and avoids the risk of coordination errors that may occur when multiple people work together, further improving the independence and safety of the operation.

[0048] In each embodiment, such as Figure 2 and Figure 5As shown, the height support frame 130 is connected to the roller conveyor 110 at the first end 111, and the height support frame 130 is located below the roller conveyor 110, so that the first end 111 is higher than the second end 112; and the height support frame 130 and the roller conveyor 110 are configured to be located above the smoke stack 200, that is, the height support frame 130 and the roller conveyor 110 are configured to be located on the top 210 of the smoke stack 200, and the rollers 120 are evenly distributed on the roller conveyor 110; in some embodiments, such as Figure 9 or Figure 10 As shown, the rollers 120 are arranged in an array on the roller conveyor 110. In this way, through the height difference design, the medicine box 300 is driven by its own gravitational potential energy, which eliminates the need for energy consumption; the arrayed rollers 120 reduce the moving resistance of the medicine box 300 and improve the smoothness of the conveying; the medicine box conveying device 100 above the tobacco stack is directly mounted on the top 210 of the tobacco stack 200, requiring no additional installation space, adapting to the limited working environment above the tobacco stack 200, simplifying the operation process and improving space utilization.

[0049] To avoid too many lines causing interference, and Figure 3 Compared to the 200 shown smokestacks, Figure 4 , Figure 5 , Figure 6 and Figure 8 The depicted smokestack 200 does not show the lines of its top 210, but this does not affect the understanding of those skilled in the art regarding its shape and structure. Figure 4 , Figure 5 , Figure 6 and Figure 8 The normal understanding of the smokestack 200 shown.

[0050] In each embodiment, the roller conveyor 110 is used to carry the medicine box 300. When the height support frame 130 is in a supported state, the medicine box 300 located at the first end 111 moves to the second end 112 under the action of gravity and the rolling action of the roller 120. As an example, such as Figure 2 or Figure 5 As shown, the height support frame 130 is in a supported state; as Figure 9 As shown, the height support frame 130 is not in a supported state. In this embodiment, it can also be understood that the height support frame 130 is in a retracted state. In some embodiments, such as Figure 1 and Figure 9As shown, the height support frame 130 is a foldable support frame, and one end of the height support frame 130 is rotatably connected to the roller conveyor 110 at the first end 111. In this embodiment, the height support frame 130 is H-shaped. In other embodiments, the height support frame 130 may also be U-shaped or other shapes. This structural design, through the synergistic effect of gravity and the rolling of the roller 120, enables the automatic unpowered conveying of the medicine box 300, reducing energy consumption; the foldable height support frame 130, such as the H-shaped or U-shaped structure, supports state switching, such as supporting or retracting, which is beneficial for adapting to different operating scenarios: in the supporting state, an inclined conveying slope is formed to drive the medicine box to move; in the retracted state, the device is easy to fold and store, saving storage space; the rotatable connection design improves structural flexibility, and combined with the diverse shape design, enhances the adaptability of the device to the complex space of the top 210 of the tobacco stack 200, while also facilitating single-person carrying and rapid deployment, further improving operating efficiency and convenience.

[0051] In practical applications, as an example, such as Figure 5 and Figure 6 As shown, operator 500 ascends to the top 210 of the chimney stack 200 via a height platform 400. Exemplarily, the height platform 400 includes a liftable platform and an A-frame ladder. This structural design facilitates operator 500's work on the top 210 of the chimney stack 200. The liftable platform, through a mechanical or hydraulic lifting mechanism, flexibly adjusts its height to adapt to chimney stacks 200 of different heights, allowing operator 500 to smoothly reach the top 210 of the chimney stack 200 without climbing, reducing the risk of climbing. An A-frame ladder can also be used for ascent; its simple structure, quick deployment, and ease of carrying and transport make it suitable for temporary or small-to-medium-sized chimney stack scenarios, meeting diverse operational needs.

[0052] In some of these embodiments, such as Figure 6 and Figure 7As shown, the medicine box conveying device 100 above the tobacco stack has a limiting pin hole 140 on the roller conveyor 110. The limiting pin hole 140 is used to insert a limiter 150 to limit the extreme position of the medicine box 300 on the roller conveyor 110. In some embodiments, the medicine box conveying device 100 above the tobacco stack also includes the limiter 150. In some embodiments, the limiter 150 includes a vertical rod 151 detachably inserted into the limiting pin hole 140 and a horizontal rod 152 blocking the medicine box 300, and the vertical rod 151 and the horizontal rod 152 are arranged perpendicularly to each other. This structural design allows for several advantages. First, the engagement of the limit pin hole 140 and the limiter 150 enables flexible adjustment of the conveying endpoint position of the medicine box 300 according to actual operational needs. Second, the crossbar 152 prevents the medicine box 300 from moving, avoiding it from rushing out of the end of the roller conveyor 110 due to inertia, ensuring that the medicine box 300 stays in the preset position and improving operational accuracy. Third, the limiter 150 is detachable and its insertion position is adjustable, supporting the limitation of movement limits at different points on the roller conveyor 110, adapting to the positioning needs of medicine boxes 300 of different sizes or in different operational scenarios. Fourth, this design prevents the medicine box 300 from accidentally slipping or colliding with the tobacco stack 200, reducing the risk of damage to the items, and avoiding accidental injury to operators due to uncontrolled medicine boxes, further optimizing the operational safety environment.

[0053] In some of these embodiments, such as Figure 10As shown, the medicine box conveying device 100 above the tobacco stack also includes a remote pushing component 160, which includes an operating lever 161, a transmission component 162, and a pusher block 163. The pusher block 163 is movably connected to the roller conveyor 110 at the second end 112. The operating lever 161 is connected to the height support frame 130 or to the roller conveyor 110 at the first end 111, and the operating lever 161 is connected to the pusher block 163 through the transmission component 162, for applying force to the medicine box 300 located at the second end 112 through the pusher block 163, so that the medicine box 300 leaves the roller conveyor 110. On the one hand, this way only one operator needs to move the roller conveyor 110 to continue placing the medicine box 300, which helps to protect the tobacco stack 200. Furthermore, operators do not need to approach the end of the roller conveyor 110 at the top 210 of the tobacco stack 200. By remotely driving the pusher block 163 at the first end 111 or support frame position via the operating lever 161, the medicine box 300 can be pushed out from the second end 112 of the roller conveyor 110, avoiding repeated climbing or approaching the edge of the tobacco stack 200 and reducing the risk of falling. On the other hand, combined with the position adjustment of the roller conveyor 110 or the remote pushing component 160, a single person can complete the entire process of conveying and unloading the medicine box 300 without the need for collaborative work, further saving labor costs and improving operational independence. Moreover, the pusher block 163 applies force through the mechanical transmission of the transmission component 162, preventing the medicine box 300 from sliding freely and impacting the tobacco stack 200 due to gravity, reducing the risk of stack shaking or collapse, and protecting the stability of the tobacco stack; at the same time, it reduces the collision damage rate of the medicine box and improves material safety. On the other hand, the operating lever 161 is fixedly connected to the height support frame 130 or the roller conveyor 110. Using the structure of the device itself as the force fulcrum, there is no need to install additional drive equipment. Unloading can be achieved through simple push and pull actions, which simplifies the operation process and improves work efficiency.

[0054] In some of these embodiments, such as Figure 10As shown, the remote pushing component 160 also includes an elastic reset member 164 connected to the roller conveyor 110 at the second end 112; the push block 163 is disposed on the elastic reset member 164, and the push block 163 is used to overcome the force of the elastic reset member 164 under the action of the transmission member 162, and push the medicine box 300 at the second end 112 away from the first end 111; and reset under the action of the elastic reset member 164 when the transmission member 162 is not exerting force. This structural design allows the elastic reset member 164, such as a spring or elastic rubber, to automatically drive the push block 163 back to its initial position after unloading, eliminating the need for manual reset, reducing repetitive adjustments by operators, and improving unloading efficiency. Furthermore, the elastic reset member 164 and the push block 163 are integrated at the end of the roller conveyor 110, eliminating the need for an additional drive mechanism and simplifying the structure of the remote pushing component 160; the elastic reset process uses flexible force transmission, reducing mechanical wear between the transmission member 162 and the push block 163, and improving the durability of the device. On the other hand, the automatic reset function of push block 163 allows the device to quickly enter the next unloading state. Combined with the continuous conveying of roller conveyor 110, it realizes full automation of the entire process from conveying to unloading of medicine box 300, and enhances the continuity of operation.

[0055] In some of these embodiments, such as Figure 11As shown, the medicine box conveying device 100 above the tobacco stack also includes an extension plate 170 and height stops 180 located on the extension plate 170. The extension plate 170 is connected to both sides of the roller conveyor 110, and the height stops 180 are used to block the medicine boxes 300 on both sides of the roller conveyor 110 to prevent the medicine boxes 300 from detaching from the roller conveyor 110. In some embodiments, the height of the height stops 180 is 30% to 60% of the height of the medicine boxes 300; in some embodiments, the height stops 180 is an elastic cylindrical rod. This structural design, on the one hand, forms physical limiting boundaries with the height stops 180 on both sides of the extension plate 170, preventing the medicine boxes 300 from slipping off the sides of the roller conveyor 110 due to shaking or tilting during the conveying process, ensuring that the medicine boxes 300 move in a straight line along a predetermined path, avoiding material falling and causing loss or safety hazards, and ensuring that the medicine boxes 300 are conveyed to the appropriate target position. On the other hand, the height of the baffle is set to 30% to 60% of the height of the medicine box. This effectively prevents the medicine box from tipping over without hindering operators from picking up and placing the medicine box 300 from the side of the roller conveyor due to excessive height. This is especially suitable for scenarios where the position of the medicine box 300 needs to be frequently adjusted, improving operational flexibility. Furthermore, the height baffle 180, with its elastic cylindrical rod structure, absorbs the impact force through elastic deformation when the medicine box 300 is involved in a side collision, preventing rigid collisions from causing wear or deformation of the medicine box 300 surface, thus improving operational safety and material protection. Moreover, the height baffle 180 is directly fixed to both sides of the roller conveyor via the extension plate 170, eliminating the need for additional complex installation components and reducing assembly difficulty. The elastic material of the baffle is wear-resistant and easy to clean, reducing long-term maintenance costs and extending the service life of the medicine box conveying device 100 above the tobacco stack.

[0056] The following example illustrates the above-pile pesticide box conveying device 100. When new tobacco leaves are received, a low-oxygen environment needs to be created in the tobacco storage to kill tobacco insects. This is achieved by evenly placing oxygen-absorbing pesticide boxes above the tobacco stack. The above-pile pesticide box conveying device 100 serves as a convenient conveying device for the pesticide boxes, facilitating the placement and collection of the pesticide boxes 300. By optimizing the equipment structure, the above-pile pesticide box conveying device 100 improves operational convenience, stability, and safety, reduces labor intensity, and is particularly suitable for controlled atmosphere storage environments.

[0057] The medicine box conveying device 100 above the tobacco stack uses roller conveyor 110 and roller 120, together with height support frame 130, to form a conveying ramp with a certain inclination, which is easy to temporarily lay. Utilizing the gravity of the medicine box 300 and the rolling action of the roller 120, two operators work together to transport the medicine box containing oxygen remover, allowing the personnel engaged in the operation to conveniently place or retrieve the medicine box 300, simply by flexibly adjusting the position of the first end 111 or the second end 112 of the roller conveyor 110.

[0058] As an example, the medicine box conveying device 100 above the tobacco stack can also be equipped with a removable and pluggable stop at different positions as a limiting design. For example, at intervals along the roller conveyor 110, a set of insertion ports, i.e., limiting pin holes 140, for inserting the limiter 150 can be designed as limiting devices. Operators crawling above the tobacco stack only need to carry the limiter 150, such as the limiting stop bar, into the work area, avoiding the need to transport the medicine boxes 300 back and forth in a confined space.

[0059] As an example, the medicine box conveying device 100 above the tobacco stack uses a foldable support frame as the height support frame 130. When the conveying device is recycled, the height support frame 130 of the conveying device can be folded and stored to reduce storage space waste.

[0060] After the 200 stacks of tobacco are completed, as follows Figure 3 As shown, and not as a limitation, after stacking, the top of the smoke stack 200 is only about 70 centimeters away from the top of the warehouse. The operators, i.e., the workers, need to crouch and move on top of the smoke stack 200 210, while carrying a kit 300 containing oxygen absorbers. Working in such a confined space is physically demanding for the operators, and there is a potential safety risk of them bumping into fire pipes or lighting fixtures due to fatigue.

[0061] A two-person cooperative operation process is described as follows: First, operator A, carrying the limiter 150, crawls into the innermost part of the tobacco stack 200 where the medicine boxes 300 need to be placed. Operator B assists in laying the medicine box conveying device 100, i.e., the roller conveyor device, on the top 210 of the tobacco stack 200, and inserts the limiter 150 into the limit pin hole 140 near the farthest end, i.e., the second end 112. Figure 6 As shown. Operator B places the medicine box 300 onto the roller conveyor 110 from the outside, allowing the medicine box 300 to slide towards operator A along the roller conveyor 110. The medicine box 300 will stop at the limiter 150, whereupon operator A removes it and places it in the correct position, as shown. Figure 8 As shown. Next, operator B successively feeds the remaining medicine boxes 300 into the work space, while operator A moves outward and changes the position of the limiter 150 to facilitate placing the medicine boxes 300 in different locations. Finally, the two operators retract the medicine box conveyor 100 above the tobacco stack and place the limiter 150 and roller conveyor 110 in a suitable position within the storage area. The method of collecting the medicine boxes 300 is the reverse of the placement method and will not be described in detail here.
