Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tobacco manufacturing technology, specifically relating to a tobacco leaf industrial grading and sorting table. Background Technology
[0002] The grading and sorting process in the tobacco industry is the "front end" of the tobacco leaf threshing and re-drying process. Its main task is to select and grade materials such as virgin tobacco leaves according to indicators such as maturity, leaf structure, oil content, color and length, classify virgin tobacco leaves into different categories, and remove impurities such as unusable tobacco leaves such as green tobacco and moldy tobacco, as well as non-tobacco impurities such as hemp fibers and chicken feathers.
[0003] After the first-cured tobacco leaves are delivered to the industrial grading site, the grading personnel typically place the leaves on the existing sorting tables to carry out the grading and sorting work. Because the tabletops of these sorting tables are smooth, flat stainless steel plates, this presents the following three drawbacks:
[0004] First, after a period of time, a lot of dust and soot will remain on the table, making it difficult to keep clean. As the grading and sorting work continues, the dust and soot on the table will increase, affecting the grading and sorting work. At the same time, the leaf grading personnel need to clean it frequently, which increases the labor intensity of the leaf grading personnel.
[0005] Secondly, because the debris collection bins are placed on the ground, the staff have to bend over to put the debris into the bins each time they remove it. This makes the leaf sorting and grading staff prone to fatigue, increases the workload, and can easily cause physical discomfort. At the same time, it also makes it easy for the leaf sorting and grading staff to kick the debris collection bins while walking, which makes it inconvenient for them to move around freely.
[0006] Third, due to factors such as the height of the leaf selection and grading personnel, the height of the existing selection table is fixed and cannot be adjusted, resulting in poor adaptability to different leaf selection and grading personnel.
[0007] Therefore, how to design a tobacco leaf grading and sorting table to reduce the labor intensity of leaf sorting and grading personnel, facilitate their free movement, and be suitable for leaf sorting and grading personnel of different heights has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0008] The purpose of this invention is to provide a grading and sorting table for tobacco leaf industry to solve the above-mentioned technical problems in the prior art.
[0009] To achieve the above objectives, the present invention provides the following technical solution:
[0010] A tobacco leaf grading and sorting table includes a support frame, a filter screen, a collection box, and a debris collection bin. The support frame includes a top frame and four support legs. The top frame is rectangular and horizontally positioned. The upper ends of the four support legs are perpendicularly connected to the lower sides of the four corners of the top frame. The filter screen is disposed within the top frame. The collection box is disposed on the ground directly below the filter screen. The top of the collection box is open. Adjustable feet are provided at the lower ends of the four support legs. Hooks are provided at the front end of the left side rod and the rear end of the right side rod of the top frame. The debris collection bin is provided with a hanging ring for engaging with the hooks.
[0011] Preferably, two hoppers are arranged opposite each other on the left and right sides directly below the filter screen, and the upper ends of the two hoppers are respectively connected to the top frame; there are two collection boxes, which are located directly below the two hoppers, and the openings of the two collection boxes correspond one-to-one with the discharge ports of the two hoppers.
[0012] Preferably, the cross-section of the hopper is an isosceles trapezoidal structure that is larger at the top and smaller at the bottom.
[0013] Preferably, a first connecting rod is provided between the two supporting legs located on the left side.
[0014] Preferably, a second connecting rod is provided between the two support legs located on the right side.
[0015] Preferably, it further includes a lighting frame and a lighting fixture. The lighting frame includes a horizontal bar, a left vertical bar and a right vertical bar that are perpendicularly connected to the left and right ends of the horizontal bar, respectively. The horizontal bar, the left vertical bar and the right vertical bar together form an inverted U-shaped structure.

[0017] Preferably, a second reinforcing rod is provided between the rear side rod of the top frame and the two supporting legs located at the rear end.
[0018] The beneficial effects of this utility model are as follows:
[0019] This utility model relates to a tobacco leaf grading and sorting table. During use, tobacco fragments and dust fall through a filter into a collection box, preventing them from remaining on the table surface as in existing technologies. This eliminates the need for frequent table cleaning, effectively preventing disruption to the grading and sorting process and reducing labor intensity. Furthermore, the waste collection bin is secured to the top frame via a hanging ring, rather than being placed on the ground. This allows grading personnel to easily place removed debris into the collection bin without bending over, further reducing labor intensity and minimizing fatigue. It is less likely to cause physical discomfort; since the debris collection bins are fixed to the top frame, leaf sorting and grading personnel do not have to worry about kicking them while moving around, thus facilitating their movement; since the two debris collection bins are fixed to the front end of the left side bar and the rear end of the right side bar of the top frame respectively, meaning the two debris collection bins are located on the right-hand side of the leaf sorting and grading personnel on both sides, it is convenient for them to put the removed debris into the debris collection bins, improving the efficiency of the removal work; furthermore, since each support leg is equipped with an adjustable foot cup at the bottom, the height of the support frame can be easily adjusted, making it suitable for leaf sorting and grading personnel of different heights.

[0030] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps set forth in these embodiments do not limit the scope of the present invention.
[0031] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.
[0032] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.
[0033] In all the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.
[0034] like Figures 1 to 3 As shown, this utility model embodiment provides a tobacco leaf industrial grading and sorting table, which includes a support frame, a filter screen 41, a collection box 71, and a debris collection bin 31. The support frame includes a top frame and four support legs 15. The top frame has a rectangular structure and is horizontally arranged. The upper ends of the four support legs 15 are respectively vertically connected to the lower sides of the four corners of the top frame. The filter screen 41 is arranged in the top frame, and the collection box 71 is arranged on the ground directly below the filter screen 41. The top of the collection box 71 is open, and the lower ends of the four support legs 15 are all provided with adjustable feet 21. Hooks are provided on the front end of the left side rod 11 and the rear end of the right side rod 12 of the top frame, and the debris collection bin 31 is provided with a hanging ring for cooperating with the hooks.
[0035] The tobacco leaf grading and sorting table provided in this embodiment allows tobacco fragments and dust to fall through the filter 41 into the collection box 71 during use, avoiding the situation in the prior art where tobacco fragments and dust remain on the table and eliminating the need for frequent table cleaning. This effectively prevents the grading and sorting work from being affected and reduces labor intensity. Simultaneously, the debris collection bin is fixed to the top frame via a hanging ring, rather than being placed on the ground. This allows grading personnel to place the removed debris into the collection bin without bending over, further reducing labor intensity and minimizing fatigue. Physical discomfort; since the debris collection bin is fixed to the top frame, the leaf sorting and grading personnel do not have to worry about kicking the debris collection bin when walking, thus facilitating their free movement; since the two debris collection bins are respectively fixed to the front end of the left side bar 11 and the rear end of the right side bar 12 of the top frame, that is, the two debris collection bins are located on the right-hand side of the two leaf sorting and grading personnel standing on the left and right sides of the support frame, it is convenient for the leaf sorting and grading personnel to put the removed debris into the debris collection bin 31, improving the efficiency of the removal work; and since each support leg is equipped with an adjustable foot cup 21 at the lower end, the height of the support frame can be easily adjusted, thus making it suitable for leaf sorting and grading personnel of different heights.
[0036] Furthermore, two hoppers 61 are arranged opposite each other on the left and right sides directly below the filter screen, and the upper ends of the two hoppers 61 are respectively connected to the top frame; there are two collection boxes 71, which are located directly below the two hoppers, and the openings of the two collection boxes correspond one-to-one with the discharge ports of the two hoppers. This design ensures that the smoke and dust on the left and right sides of the filter screen fall into their respective collection boxes through the two hoppers; at the same time, the hoppers provide a good guiding effect.
[0037] Preferably, the cross-section of the discharge hopper 61 is an isosceles trapezoidal structure, wider at the top and narrower at the bottom, which allows for better collection of slag and dust. It is understood that the dimensions of the left and right discharge hoppers can be the same; the adjustable feet are adjustable in the vertical direction, a common component in the prior art, and will not be described in detail here.
[0038] Furthermore, a first connecting rod is provided between the two support legs 15 located on the left side, thereby effectively improving the overall strength of the support frame.
[0039] Specifically, a second connecting rod 17 is provided between the two support legs 15 on the right side to further improve the overall strength of the support frame.
[0040] In one specific embodiment, the filter screen 41 has square holes of 40mm × 40mm. The filter screen is detachably connected to the top frame.
[0041] Furthermore, the tobacco leaf industrial grading and sorting table also includes a lighting frame and a lighting fixture 53. The lighting frame includes a horizontal bar 51, a left vertical bar 52 and a right vertical bar 54 perpendicularly connected to the left and right ends of the horizontal bar, respectively. The horizontal bar, the left vertical bar, and the right vertical bar together form an inverted U-shaped structure. The lower end of the left vertical bar passes through the middle of the left side bar and connects to the middle of the first connecting rod. The lower end of the right vertical bar passes through the middle of the right side bar and connects to the middle of the second connecting rod. The lighting fixture is mounted on the horizontal bar. With this design, the lighting fixture can be turned on to provide illumination in low light conditions or at night, ensuring that the grading and sorting work can proceed smoothly.
[0042] Preferably, a first reinforcing rod 16 is provided between the front side rod 13 of the top frame and the two supporting legs located at the front end to further improve the overall strength of the support frame.
[0043] Specifically, a second reinforcing rod is provided between the rear side rod 14 of the top frame and the two supporting legs located at the rear end, thereby further improving the overall strength of the support frame.
[0044] Since different leaf sorting and grading personnel may have different operating habits (e.g., some are right-handed, some are left-handed), in another embodiment, hooks are provided on the front and rear ends of the left side rod 11 of the top frame, and hooks are also provided on the front and rear ends of the right side rod 12. With this design, leaf sorting and grading personnel only need to hang the debris collection bin on the corresponding hooks using the hanging rings according to their operating habits, thus better meeting the needs of different leaf sorting and grading personnel. In other embodiments, other detachable connection methods can also be used between the debris collection bin and the top frame, such as snap-fit connections or screw connections.
[0045] This invention allows dust and tobacco debris generated during tobacco leaf grading and sorting to fall directly into a collection box through a sieve. Simultaneously, grading personnel can easily place debris into a collection bin located beside their dominant hand and fixed to the top frame, facilitating debris collection, maintaining a clean and tidy work area, and simplifying on-site management. Furthermore, it avoids the dust accumulation on existing work surfaces that easily leads to dust storms, which is beneficial to the health of grading personnel. It also eliminates the need for frequent cleaning of accumulated dust and tobacco debris on existing work surfaces, reducing the workload of grading personnel.
[0046] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
