[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a screening device for facilitating the quality grading of Chinese medicinal materials, comprising: a medicine rack 1, a vibrating box 2 fixedly connected to the bottom of the medicine rack 1, a sieving frame 3 provided on the upper surface of the vibrating box 2, a limiting component 4 fixedly connected to the inner surface of the sieving frame 3, and a screen 5 movably connected to the inner surface of the limiting component 4. The screen 5 can be quickly disassembled and assembled by the clamping and limiting of the limiting component 4.

[0021] In use, the screw 48 in the limiting component 4 is connected to the positioning seat 47 and the handle 49 by rotation. In conjunction with the clamping structure between the limiting block 410 and the screen 5, rotating the handle 49 can drive the limiting block 410 to rise and fall, quickly releasing or fixing the screen 5. At the same time, the cooperation structure between the guide groove 45 and the bottom guide roller 413 of the screen 5 reduces the friction when the screen 5 is disassembled and assembled, allowing it to slide smoothly along the guide. This makes it easy to replace the corresponding screen 5 according to different specifications of Chinese medicinal materials, improving the adaptability of the device.

[0022] The limiting component 4 includes a fixing plate 41, which is fixedly connected to the inner wall of the screening frame 3 in two sets. The fixing plate 41 is movably connected to a fixing bolt 42 on one side, and the fixing bolt 42 is movably connected to the four corners of the fixing plate 41 in four sets.

[0023] A limiting clamp 43 is fixedly connected to the inner surface of the fixing plate 41. A guide groove 45 is provided on the side of the limiting clamp 43 away from the fixing plate 41. A bottom baffle 44 is fixedly connected to the tail end of the fixing plate 41. The bottom baffle 44 is fixedly connected between the two sets of fixing plates 41.

[0024] A fixing ring 46 is fixedly connected to the upper surface of the limiting clamp 43, and a positioning seat 47 is fixedly connected to the upper surface of the fixing ring 46. A screw 48 is rotatably connected inside the positioning seat 47, and a handle 49 is fixedly connected to the top of the screw 48. A limiting block 410 is fixedly connected to the end of the screw 48 away from the handle 49. The screw 48 is connected through the upper and lower ends of the limiting clamp 43, and the limiting block 410 clamps the edge of the screen 5.

[0025] A guide seat 411 is fixedly connected to the surface of the limiting clamp 43 on the side opposite to the limiting block 410. A limiting groove 412 is opened on the inner surface of the guide seat 411. The limiting groove 412 is fixedly connected to the inner wall of the guide seat 411. The limiting groove 412 is movably connected to the bottom of the screen 5.

[0026] In operation, in its initial state, the upper medicine rack 1 holds the Chinese medicinal materials to be screened, and its bottom is fixedly connected to the vibrating box 2, which provides the power for screening. The screening rack 3 is installed on the upper surface of the vibrating box 2. The internal limiting component 4 is fixed to the inner wall of the screening rack 3 by two sets of fixing plates 41, and four sets of fixing bolts 42 are distributed at the four corners of the fixing plates 41 to enhance the connection stability between the fixing plates 41 and the screening rack 3. The screen 5 is fixed by the limiting component 4. At this time, the limiting clamp 43 clamps the screen 5 from both sides, the bottom baffle 44 restricts the longitudinal displacement of the screen 5, and the limiting groove 412 of the guide seat 411 is movably connected to the bottom of the screen 5 to further improve the installation stability of the screen 5.

[0027] When it is necessary to replace the screen 5 to meet the grading requirements of different specifications of Chinese medicinal materials, the operator can turn the handle 49 to drive the screw 48 to rotate within the positioning seat 47. Since the screw 48 passes through the limiting clamp 43 and is fixedly connected to the limiting block 410, the rotation of the screw 48 will cause the limiting block 410 to move in the vertical direction. When the handle 49 is turned upward, the limiting block 410 is lifted upward, releasing the clamp on the top of the screen 5; at this time, the screen 5 can be pulled out along the guiding direction of the guide groove 45 and the limiting groove 412, completing the disassembly. When installing a new screen 5, insert the screen 5 into the guide groove 45. During the installation and insertion of the screen 5, the guide roller 413 at the bottom of the screen 5 can guide the screen 5 and reduce friction, preventing the screen 5 from getting stuck during insertion. Continue until the screen 5 is in contact with the bottom baffle 44. Then, turn the handle 49 in the opposite direction to move the limiting block 410 downward and press the top of the screen 5. The screen 5 is quickly fixed by the cooperation of the limiting block 410 and the limiting clamp 43.

[0028] When the device is running, the vibrating box 2 starts and generates vibration, which is transmitted to the screen 5 through the screening frame 3. The Chinese medicinal materials to be screened enter the screen 5 from the upper medicine rack 1. Under the action of vibration, the Chinese medicinal materials that meet the aperture of the screen 5 pass through the screen 5 and are graded, while the larger-sized Chinese medicinal materials remain in the screen 5. During this process, the multiple fixing structures of the limiting component 4 ensure that the screen 5 will not shift or fall off under high-frequency vibration. The cooperation between the guide groove 45 and the limiting groove 412 can also reduce the frictional wear between the screen 5 and the limiting component 4, and extend the service life of the components.

[0029] Through the above structural design, the device can achieve efficient grading of Chinese medicinal materials through vibration, and can also quickly complete the disassembly and replacement of the screen 5 through the linkage structure of the screw 48, the handle 49 and the limit block 410 of the limiting component 4, so as to meet the quality grading requirements of different Chinese medicinal materials and improve the practicality and ease of operation of the device.
