The first feature being "below", "below the bottom", and "under the bottom" of the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the horizontal height of the first feature is lower than that of the second feature.

[0029] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0030] Such as Figure 1 AndFigure 2 As shown in the figure, the tobacco leaf sorting workbench of the embodiment of the present utility model includes a frame 1, a support plate 2, a surrounding wall 3, a filter element 4 and a discharge pipe 5. A support plate 2 is horizontally arranged on the frame 1. A surrounding wall 3 is annularly protruded along the outer periphery on the support plate 2. The surrounding wall 3 encloses to form a receiving groove 30. The support plate 2 is vertically penetrated with a communication port 21. A working area is formed between the communication port 21 and the groove wall of the receiving groove 30 on the support plate 2. The working area is used for operators to sort tobacco leaves. The receiving groove 30 is communicated with the discharge pipe 5 through the communication port 21. A filter element 4 is detachably arranged at the communication port 21. The discharge pipe 5 is used to collect the fine tobacco leaves screened out by the filter element 4.

[0031] It can be understood that by arranging the surrounding wall 3 on the support plate 2 to form the receiving groove 30, the storage capacity of large tobacco leaves on the support plate 2 can be improved. The blocking of the surrounding wall 3 can also prevent the tobacco leaves from sliding off the support plate 2, reducing the occurrence of pollution caused by the large tobacco leaves falling. By arranging the filter element 4 on the communication port 21, impurities or fine leaves and other sundries on the large tobacco leaves can be filtered, removing useless sundries, ensuring the quality of large tobacco leaves. At the same time, the filter element 4 can also enhance the heat dissipation effect of the re-dried cut tobacco. And the filter element 4 is detachably connected to the communication port 21, which is convenient for disassembly and assembly, so as to facilitate the subsequent cleaning or replacement of the filter element 4, improving the maintenance efficiency of the tobacco leaf sorting workbench. By collecting the impurities or fine leaves on the large tobacco leaves through the discharge pipe 5, the operation of manual shoveling is reduced, thereby reducing the dispersion of sundries, with simple operation and convenient collection, improving the tobacco leaf sorting efficiency.

[0032] Optionally, at least part of the top surface of the support plate 2 is inclined. The top inclined surface of the support plate 2 is inclined downward from the end far away from the communication port 21 towards the end adjacent to the communication port 21. Through the setting of the top inclined surface of the support plate 2, it is beneficial for the impurities or fine leaves falling on the top surface of the support plate 2 to slide along the top inclined surface to the communication port 21, improving the cleaning convenience of the top surface of the support plate 2.

[0033] In this embodiment, as Figure 4 shown, a supporting portion 22 is protruded on the cavity wall of the communication port 21. The filter element 4 abuts on the supporting portion 22. Through the setting of the supporting portion 22, the filter element 4 can be directly placed in the communication port 21 and supported on the supporting portion 22 to complete the installation of the filter element 4, with convenient installation. It should be noted that the top surface of the filter element 4 should always be lower than the top surface of the support plate 2 to ensure that the sundries on the support plate 2 can smoothly slide from the filter element 4 into the receiving pipe.

[0034] Furthermore, as Figure 3As shown, the filter element 4 includes a fixing frame 41 and a filter screen 42. The filter screen 42 is arranged in the hollow of the fixing frame 41. The outer peripheral side wall of the fixing frame 41 is recessed with a notch, and the notch runs through both sides of the fixing frame 41 in the vertical direction. The peripheral side of the filter element 4 is close to the cavity wall of the connecting port 21. The notch is arranged so that when the operator needs to replace the filter element 4, he can put his hand into the notch to lift the filter element 4, thereby improving the convenience of removing the filter element 4. The debris is effectively filtered out by the filter 42, that is, large pieces of tobacco leaves stay on the filter 42. The mesh size of the filter 42 should be larger than 25mm and smaller than 50mm. For example, the mesh size of the filter 42 is 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, etc. If the mesh size is too small, small leaves or impurities cannot pass through. If the mesh size is too large, large pieces of tobacco leaves may fall off, thus losing the filtering nature. The mesh size is moderate, which can not only ensure the filtering of small leaves, but also prevent large pieces of tobacco leaves from falling off, thereby ensuring the filtering function of the filter 42.

[0035] Optionally, the filter element 4 further includes two handles 43, and through holes are respectively provided on the frame of the fixed frame 41 arranged at intervals along the first direction, and a handle 43 is slidably connected to each through hole, and both ends of the handle 43 along the vertical direction can abut against the fixed frame 41. Through the provision of the handle 43, the operator can pull the filter element 4 out of the connecting port 21 by pulling the handle 43, which is convenient for the removal of the filter element 4. Through the provision of the through holes, when the filter element 4 is installed at the connecting port 21, the handle 43 can slide to the bottom of the fixed frame 41 due to its own gravity, and only the stopper of the filter element 4 is exposed in the fixed frame 41, so as to prevent the handle 43 from protruding from the fixed frame 41, affecting the placement and filtering of tobacco leaves, and preventing tobacco leaves from colliding with the handle 43 to form more broken leaves, thereby improving the safety of the filter element 4.

[0036] Furthermore, if Figure 4 As shown, the tobacco leaf sorting workbench also includes a baffle 6, which is used to block the connecting port 21. By setting the baffle 6, the connecting port 21 can be blocked so that the top surface of the support plate 2 is a closed plane, and the area of the working area is increased, so that the operator can select it. Usually, when the large tobacco leaves have not been processed by stem extraction, the connecting port 21 can be directly selected without blocking. The large tobacco leaves are left, and the impurities or the fine and broken leaves produced can fall into the discharge pipe 5 through the filter 4. When the large tobacco leaves are formed into tobacco leaves after stem extraction and re-baking, the tobacco leaves are raw materials that can directly enter the cigarette production process. They have low moisture, are dry, easy to break, and have high requirements for leaf selection sanitary conditions. Therefore, at this time, it is necessary to use the baffle 6 to block the connecting port 21 so that the top surface of the support plate 2 is a closed cover to reduce the generation of tobacco leaves. After the selection is completed, the baffle 6 is opened, and the fine and broken tobacco leaves on the support plate 2 are gently pushed to the connecting port 21 to fall into the collection bucket through the discharge pipe 5 for collection.

[0037] Further, the baffle 6 is detachably connected to the support plate 2, and the baffle 6 abuts against the supporting portion 22. When selecting the redried cut tobacco, the filter element 4 is removed from the communication port 21, and the baffle 6 is directly placed on the supporting portion 22 to complete the installation of the baffle 6, which is convenient for disassembly and assembly.

[0038] In other embodiments, an installation groove 23 is recessed on one side wall of the communication port 21. A first driving member, a second driving member and the baffle 6 are arranged in the installation groove 23. The second driving member is in transmission connection with the baffle 6 to drive the baffle 6 to move in the vertical direction. The first driving member is in transmission connection with the second driving member to drive the second driving member and the baffle 6 to expose the installation groove 23 in the horizontal direction. By using the arrangement of the driving members, the baffle 6 can automatically contract into the installation groove 23 to ensure the normal operation of the filter element 4, or extend out to block the communication port 21 to ensure that the top surface of the support plate 2 is a closed plane. For example, taking the baffle 6 in the contracted state as an example, the first driving member drives the second driving member and the baffle 6 to expose the installation groove 23 in the horizontal direction, and the second driving member drives the baffle 6 to move in the vertical direction so that the top surface of the baffle 6 is flush with the top surface of the support plate 2.

[0039] Further, the top surface of the baffle 6 can be flush with the top surface of the support plate 2 to ensure that the top surface of the support plate 2 is a closed plane after the baffle 6 blocks the communication port 21, reducing the formation of redried cut tobacco fragments; in addition, the side surface of the baffle 6 away from the bottom of the installation groove 23 can be flush with the notch of the installation groove 23, so that when the baffle 6 contracts into the installation groove 23, the baffle 6 can block the notch of the installation groove 23 to prevent impurities or fine tobacco leaves from falling to the installation groove 23 and being difficult to clean.

[0040] In some embodiments, as Figure 5 shown, the rack 1 includes a first bracket 11, a second bracket 12, a third driving member 13 and a third bracket 14 for bottom support. The first bracket 11 and the second bracket 12 are arranged at intervals along the second direction on the bottom side of the support plate 2. One side of the first bracket 11 away from the support plate 2 is hinged to the third bracket 14. The third driving member 13 is arranged on the third bracket 14, and the driving end of the third driving member 13 is hinged to the second bracket 12. The second direction is arranged at an angle with the vertical direction. By driving the second bracket 12 by the third driving member 13, the support plate 2 and the first bracket 11 can rotate around the hinge point between the first bracket 11 and the third bracket 14, so that the support plate 2 inclines downward from the end close to the second bracket 12 to the end close to the first bracket 11. When the selection of redried cut tobacco is completed or large-area cleaning is required daily, the third driving member 13 is started to make the support plate 2 inclined, so that the fine tobacco leaves or impurities on the support plate 2 can slide along the inclined support plate 2 to the end of the inclined plate away from the second bracket 12, improving the cleaning convenience of the top surface of the support plate 2.

[0041] Further, asFigure 4 As shown in the figure, the enclosure wall 3 includes a first side plate 31, a second side plate 32, a guide plate 33 and a sealing plate 34. Two first side plates 31 are arranged on the support plate 2 at intervals along the first direction. The length of the first side plate 31 extends along the second direction. One ends of the two first side plates 31 are connected by the second side plate 32. The other ends of the two first side plates 31 are respectively connected with guide plates 33. The two guide plates 33 are spaced apart to form a guide groove 35. The dimension of the guide groove 35 along the second direction at the end close to the second side plate 32 is larger than the dimension of the guide groove 35 along the second direction at the end far from the second side plate 32. The sealing plate 34 is used to block the notch of the guide groove 35. Among them, the first direction, the second direction and the vertical direction are arranged at an angle to each other. In this embodiment, the thickness of the side plates is the same. By arranging the guide plate 33 obliquely, when the support plate 2 is inclined for cleaning, the fine leaves or impurities can slide along the inclined guide plate 33 to the notch of the guide groove 35 for unified collection, further improving the cleaning convenience of the top surface of the support plate 2. The detachable sealing plate 34 is used to block the notch of the guide groove 35 to ensure the sealing of the enclosure wall 3 and thus reduce the occurrence of tobacco leaves slipping.

[0042] Furthermore, as Figure 5 shown in the figure, the discharge pipe 5 includes a first pipe body 51, a second pipe body 52 and a connecting pipe body 53. The first pipe body 51 is connected to the communication port 21 in a communicating manner. The first pipe body 51 and the second pipe body 52 are arranged at intervals along the first direction, and the lengths of the first pipe body 51 and the second pipe body 52 extend vertically. The first pipe body 51 is connected to the second pipe body 52 through the connecting pipe body 53. The first direction and the vertical direction are arranged at an angle. Through the spaced first pipe body 51 and the second pipe body 52, the operator can place the collection bucket below the second pipe body 52 to collect the fine leaves or impurities that slide from the communication port 21 into the discharge pipe 5. The second pipe body 52 is adjacent to the circumferential side of the support plate 2, avoiding the operator having to drill under the table to place or drag the collection bucket, and improving the use convenience of the discharge pipe 5.

[0043] Preferably, the second pipe body 52 is in a trumpet shape, that is, the caliber of the end of the second pipe body 52 connected to the connecting pipe body 53 is smaller than the caliber of the end of the second pipe body 52 far from the connecting pipe body 53, and the caliber of the end of the second pipe body 52 far from the connecting pipe body 53 should be slightly smaller than the caliber of the collection bucket. The structural design of the second pipe body 52 can prevent the materials discharged from the discharge pipe 5 from accumulating at the center position of the collection bucket, and the fine leaves or impurities can spread to the edge of the collection bucket, improving the collection effect of the collection bucket.

[0044] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
