[0026] The following is combined with Figure 1-5 To further explain this application in detail,

[0027] The embodiment of the present application discloses a multi-stage vibration type Chinese medicinal material screening device, comprising a flat plate screening machine 1, wherein a screening cover 2 of the flat plate screening machine 1 is provided with a hierarchically arranged pull-out screen plate 3;

[0028] The pull-out screen plate 3 includes a screen plate 5 that is pulled out and placed above each layer of support plates 4 of the screening cover 2, a convex top plate 7 that penetrates through the through holes 6 on the screening cover 2 and presses the screen plate 5 against the top of the screening cover 2 to position the screen plate 5, and screws 9 that are arranged at both ends of the convex top plate 7 and cooperate with handle nuts 8 to lock the convex top plate 7 on the screening cover 2.

[0029] By designing the pull-out screen plate 3, the user can easily adjust the screening plate 5 on each layer of the support plate 4 to meet different screening needs. This design makes it easier and more flexible to replace and adjust the screen plate. The screening cover 2 is provided with the pull-out screen plate 3 arranged in a graded manner, which can achieve multi-level screening, effectively improve the screening efficiency, and reduce the time and effort in the screening process.

[0030] The convex-shaped top plate 7 passes through the through hole 6 on the screening cover 2. The convex-shaped top plate 7 is locked and positioned on the screening cover 2 through the handle nut 8 and the screw 9, ensuring the stability and accuracy of the screen plate and avoiding loosening or falling off during the vibration screening process. In addition, by unscrewing the handle nut 8, the convex-shaped top plate 7 and the screening plate 5 can be easily disassembled and replaced. The pull-out screen plate 3 design makes cleaning and maintenance more convenient. The screen plate can be easily removed for cleaning and maintenance, keeping the equipment clean and efficient.

[0031] The support plate 4 is provided with a rectangular hole 10 for the material screened on the screening plate 5 to fall into.

[0032] The screened materials can be smoothly discharged through the rectangular holes 10 to avoid blockage and backlog, thereby ensuring continuous and smooth discharge of materials and improving production efficiency.

[0033] The support plate 4 is connected with a feed chute 11 which passes through the screening cover 2 .

[0034] The materials screened from each layer can be collected and guided to the corresponding positions to avoid confusion and cross contamination, and maintain the purity and quality of the materials. The design of the discharge chute 11 is not only conducive to the collection and diversion of materials, but also convenient for cleaning and maintenance, keeping the hygiene and functionality of the device intact, and extending the service life of the equipment.

[0035] The design of the rectangular hole 10 and the material discharge chute 11 enables the screened materials to be quickly layered, discharged and collected, thereby improving work efficiency and reducing tedious operations and manpower during the production process.

[0036] The front end of the support plate 4 is provided with a limit block 12 for limiting the front ends of the screening plate 5, and the inner wall surface of the screening cover 2 and located above the support plate 4 are provided with a limit strip 13 for limiting the top ends of the two sides of the screening plate 5;

[0037] The limiting strips 13 , the limiting blocks 12 and the screening cover 2 are formed with insertion grooves 14 for positioning and inserting the screening plate 5 .

[0038] The front end of the support plate 4 is provided with a limit block 12 for limiting the two ends of the front side of the screening plate 5, and a limit bar 13 for limiting the top ends of the two sides of the screening plate 5 is provided above the inner wall of the screening cover 2. These limit blocks 12 and limit bars 13 can effectively limit and position the position of the screening plate 5, ensuring that the screening plate 5 is in the appropriate position and remains stable, thereby avoiding falling off or shifting during vibration. The limit bars 13, the limit blocks 12 and the screening cover 2 are formed with a plug-in groove 14 for positioning and plugging the screening plate 5. This design makes the installation and replacement of the screening plate 5 easier and faster. The cooperation of the plug-in groove 14 can ensure the accurate alignment and firm fixation of the screening plate 5, thereby improving the stability and working efficiency of the equipment. Through the design of the limit blocks 12, the limit bars 13 and the plug-in groove 14, the installation, disassembly and adjustment of the screening plate 5 can become more convenient and faster, avoiding cumbersome operating steps, and reducing the time and cost of maintenance and adjustment.

[0039] The two sides of the screening cover 2 are provided with docking blocks 15, and the screw rod 9 on the convex top plate 7 passes through the round hole 16 provided on the docking block 15 and is locked by the handle nut 8. The handle nut 8 adopts a locking nut, which is a nut with an anti-loosening function and can provide a stronger locking force to prevent the nut from loosening in a vibration environment.

[0040] The design of the docking block 15 and the convex-shaped top plate 7 and the locking method through the handle nut 8 can ensure that the screening cover 2 remains stable during the vibration screening process, prevent the screening cover 2 from shifting or loosening due to vibration, and improve the overall stability and safety of the screening device. The design of the docking block 15 and the circular hole 16 allows the convex-shaped top plate 7 to be locked or loosened by simple manual operation (such as rotating the handle nut 8), which facilitates the installation, adjustment and maintenance of the screening cover 2 without the need for complicated tools or equipment. Due to the quick connection and disconnection of the screw 9 and the handle nut 8, the user can quickly replace or adjust the screening plate 5 on the screening cover 2 to meet the screening requirements of different materials, thereby improving the screening efficiency and adaptability of the equipment. Due to the quick replacement and adjustment capabilities of the screening cover 2, the equipment can be quickly repaired or replaced when a failure occurs or the screening plate 5 needs to be replaced, thereby reducing downtime and improving production efficiency.

[0041] The screening cover 2 is also provided with a loading hopper 17 for loading and feeding Chinese medicinal materials.

[0042] In the multi-stage vibration type Chinese medicinal material screening device, Chinese medicinal materials enter the device through the upper hopper 17, and the materials fall onto the pull-out screen plate 3 in the screening cover 2. Due to the vibration of the vibrator, the materials are screened on the screen plate. The size of the sieve holes on the screening plate 5 determines the particle size range of screening. Different screening plates 5 can achieve screening of different particle sizes. Since the screening cover 2 is provided with the pull-out screen plates 3 arranged in a graded manner, the materials are screened on the screen plates of different levels, realizing multi-stage screening, and improving the screening efficiency and accuracy.

[0043] The screened materials fall through the rectangular holes 10 on the support plate 4. The rectangular holes 10 are designed to avoid material blockage and ensure continuous and smooth material discharge. The material discharge chute 11 is connected to the support plate 4 to collect and guide the screened materials from each layer to the corresponding position to avoid confusion and cross contamination and maintain the purity and quality of the materials.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
