[0040] Working principle: Before using this screening device for processing Chinese herbal medicine slices, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 8 As shown, first, after the raw material is put into the screening bin 1 through the feeding port, the vibration motor 103 is started to make the entire screening bin 1 vibrate up and down, and then the two screens 303 inside are vibrated, so that the raw material powder is vibrated and screened. The uppermost screen 303 will screen out large particles of impurities, the middle screen 303 will screen out raw materials with unqualified diameters, and the bottom conveyor plate 304 will receive raw materials with qualified diameters; thereby, the device can classify and screen large particles of impurities, raw materials with unqualified diameters and qualified raw materials, so that the device can ensure the purity of Chinese medicine raw materials while screening raw materials with unqualified diameters during the screening process;

[0041] When it is necessary to increase the screening time of the raw materials, the driving motor 213 can be started to move the block 210 horizontally, so that the height of the force-bearing inclined block 208 changes due to the squeezing of the block 210, and the height of the movable column 207 changes, so that the entire screening bin 1 is tilted at a controllable angle. Finally, by controlling the tilt angle of the screening bin 1, the residence time of the raw materials on the screen 303 is controlled, so that the device can quickly discharge the materials when the feed is small, thereby reducing the working time of the equipment. When the feed is large, the material on the screen 303 is slowed down or even prevented from leaving the discharge channel 101, thereby ensuring sufficient screening.

[0042] The block 210 and the load-bearing inclined block 208 can transfer part of the weight of the screening bin 1 to the base 201, reducing the force exerted on the threaded rod 212 by the block 210, thereby increasing the service life of the threaded rod 212 and avoiding the wear and tear of the equipment caused by the cylinder body or rod body bearing a large amount of weight for a long time when adjusting the angle of a traditional hydraulic cylinder or electric push rod;

[0043] Since the drug powder contains moisture, the mesh holes on the screen 303 will gradually become clogged when the device is used for a long time, thereby affecting the screening efficiency. At this time, the screw 313 can be removed first, and then the rotary column 308 can be rotated to disengage the first locking column 310 from the first arc groove 307, and the second locking column 311 from the second arc groove 309, so that the rotary column 308 can be pulled out from the circular hole, and finally the cover plate 306 can be separated from the mounting ring 305, so that the flip door 301 can be flipped open, and the screen 303 can be pulled out from between the two inclined blocks 302, so that the disassembly and maintenance of the screen 303 is convenient.

[0044] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
