The upper end of the table leg 6 is connected to the outer side of the tabletop through a rotating joint to realize the foldable structure of the table leg 6, which is convenient for carrying and transportation.

[0030] Embodiment 2

[0031] The tabletop 1 includes a double-layer structure of an inner layer 8 and an outer layer 9. The inner layer 8 is separated from the outer layer 9, and the inner layer 8 is connected with a weight monitoring device 10. Scales 11 are provided on the left, right, and rear sides of the outer layer 9, and a storage space for a flexible ruler 12 is provided inside the outer layer 9. A color comparison card 13 is provided on the front side of the outer layer 9. Mounting holes are provided around the outer layer 9, and lamps 14 are detachably mounted in the mounting holes. An infrared spectrometer 15, an electron microscope 16, and an electronic nose 17 are provided on one side of the outer layer 9, and the infrared spectrometer 15 is suspended directly above the inner layer 8.

[0032] Specifically, the tabletop is composed of an inner layer and an outer layer. The inner layer is separated from the outer layer. The body of the weight monitoring device 10 is connected to the bottom of the outer layer, and the weighing force-bearing feet extend to contact the center of the bottom of the inner layer. When tobacco leaves are placed on the inner layer, the weight monitoring device 10 can measure the weight of the inner layer.

[0033] Scales 11 are provided on at least two vertical sides (such as the left side and the rear side) of the outer layer tabletop. The automatic measurement of the length and width of tobacco leaves is realized through the two vertical scales 11. For the positions of tobacco leaves that are not easily measured, the flexible ruler stored in the storage space on the front side of the outer layer of the tabletop can be taken out and used for measurement.

[0034] Lay the leaves flat on the grading table and record and analyze them through the near-infrared spectrometer 15. Through the electron microscope 16, the microscopic information of the tobacco leaves can be recorded as soon as the tobacco leaves are placed on it, and their grades can be automatically analyzed. At the same time, the odor components are automatically monitored through the electronic nose 17 to analyze the grade of the leaves. For the detailed technical process of judging the quality of tobacco leaves by infrared, microscopic and odor methods, specific reference can be made to (Jiang Zehui, Jiang Xiaomei, Zhou Yucheng, etc. A neural network modeling method for the relationship model between the microscopic structure of Chinese fir and its quality characteristics [J]. Scientia Silvae Sinicae, 2005, 41(4): 133-139.).

[0035] Through the colorimetric card 13, the employees conduct primary classification of the tobacco leaves. There are holes (not shown) for installing levers in the outer layer 9 area of the desktop 1, which is convenient for installing the lamp 14 and can be disassembled when not needed.

[0036] A display screen can be set directly in front of the desktop 1 to display the tobacco leaf grading results.

[0037] Example 3

[0038] The bottom of the desktop 1 is provided with lifting table legs 6. The bottom of the table legs 6 is provided with walking wheels 7.

[0039] Specifically, the height is adjusted through the lifting structure of the table legs 6 to reduce the bending action of the employees. The lifting structure can specifically adopt a telescopic sleeve structure, and the two sleeves are locked and released by locking screws. And it is convenient to carry and move the position through the walking wheels 7.

[0040] Example 4

[0041] The packing device 19 includes a compression bag 20. The compression bag 20 is provided with a tobacco leaf inlet and outlet 21. A cushion layer 26 is provided inside the compression bag 20. A negative pressure interface 22 and a binding rope inlet and outlet 23 are provided on the compression bag 20. A binding rope 25 is placed into the compression bag 20 through the binding rope inlet and outlet 23.

[0042] Specifically, the packing device 19 has a structure similar to an air compression bag 20. Its tobacco leaf inlet and outlet 21 is opened and sealed through a structure such as a self-sealing bag snap button. The negative pressure interface 22 is used to connect to a negative pressure device to suck air and thus compress the tobacco leaves inside. The binding rope 25 gradually withdraws and shortens its length during the compression of the compression bag 20 and binds the compressed tobacco leaves. After the compression is completed, the binding rope 25 is cut off and the bundled and compressed tobacco leaf package is taken out from the outlet.

[0043] A rubber damping ring can be provided on the binding rope inlet and outlet 23 to play a certain sealing role and avoid air leakage during the compression process. Even if there is slight air leakage, it will not affect the overall compression effect.

[0044] The operation process of the packing device 19 is as follows: First, one side of the compression bag 20 is hung on the hook 24 at the exit through the hanging hole on one side. Then, the tobacco leaf inlet / outlet 21 of the compression bag 20 is opened, and the binding rope 25 (specifically, a thin hemp rope) is put into the compression bag 20 and placed vertically in a circular shape (or U shape). After that, the first rope end extends out from the binding rope inlet / outlet 23. Then, a hemp sheet is placed at the bottom of the compression bag 20 as a cushion layer 26 to wrap the tobacco leaves. Then, the tobacco leaves are poured into the compression bag 20. At this time, the fluffy tobacco leaves are on the hemp sheet cushion layer 26 and between the U-shaped binding ropes 25. Then, the second rope end of the binding rope 25 is passed through the binding rope inlet / outlet 23 again. At this time, the fluffy tobacco leaves are between the circular binding ropes 25. Then, the tobacco leaf inlet / outlet 21 is merged and sealed, and a negative pressure device is connected to the negative pressure interface 22 to start compression. During the compression process, both ends of the binding rope 25 are pulled out to reduce the circular area of the binding rope 25, so as to tie up the compressed and volume-reduced tobacco leaves. When the compression is completed, the tobacco leaf inlet / outlet 21 is opened, and both ends of the binding rope 25 are pulled inward from the binding rope inlet / outlet 23 to between the tobacco leaf inlet / outlet 21. After tying a knot, the packed tobacco leaf compressed package can be taken out from the tobacco leaf inlet / outlet 21.

[0045] The working mode of this device:

[0046] By setting a grid on the tabletop 1 to make the dust and impurities fall during the grading process, and then collecting the dust and residues through the collecting device 3 connected to the negative pressure device 4 below the tabletop 1, the floating up of the residues is initially inhibited; and during the falling process of the dust and impurities, humidification is carried out through the humidifying device 5, which can promote the agglomeration of the dust and residues and further inhibit the floating up of the residues; and the humidifying device 5 can also facilitate the moisture regain of the tobacco leaves to meet the moisture content requirements during the tobacco leaf grading process. For tobacco leaves of different grades after grading, they are sent out from different outlets 18 and then enter different packing devices 19 for packing. The upper end of the table leg 6 is connected to the outside of the tabletop through a rotating joint to realize the foldable structure of the table leg 6, which is convenient for carrying and transportation.

[0047] Finally, it should be noted that: The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: They can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
