Description

Technical Field

[0001] This utility model relates to the field of screening device technology, specifically to a vibration screening device for processing traditional Chinese medicine. Background Technology

[0002] In the field of traditional Chinese medicine (TCM) processing, the screening of medicinal materials is a crucial step in ensuring efficacy and improving product quality. Vibrating screening devices, with their advantages of high screening efficiency, convenient operation, and minimal damage to medicinal materials, have become one of the most widely used screening equipment in TCM processing. The core working principle of existing TCM processing vibrating screening devices is mostly based on a vibrating motor driving a screen to generate high-frequency vibration. The relative motion between the medicinal material particles and the screen allows particles that meet the screen aperture size to pass through the screen for grading. In actual production, different types and forms of TCM materials have significantly different requirements for screening conditions. For example, light, fine-grained herbal tea materials require a gentler tilt angle to prevent the material from sliding too quickly and causing insufficient screening; while hard, larger-grained root and rhizome materials require a larger tilt angle to increase the material conveying speed and avoid prolonged residence time on the screen, which could cause crushing and damage. Furthermore, even for the same type of medicinal material, the requirements for screening accuracy and efficiency vary at different processing stages, which also necessitates adjusting the tilt angle of the screen to adapt to these variations. However, the tilt angle of the screens in existing vibrating screening devices is mostly a fixed structural design, determined during equipment manufacturing. This makes it impossible to flexibly adjust the angle according to the actual types, specifications, and process requirements of the medicinal materials being processed, resulting in poor applicability. Therefore, this utility model provides a vibrating screening device for processing traditional Chinese medicine. Utility Model Content

The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0017] like Figure 1 and Figure 2 As shown, a vibrating screening device for processing traditional Chinese medicine includes: a base frame 1, a support frame 2 on the top of the base frame 1, a first end of the support frame 2 being rotatably connected to the top of the base frame 1, and a connecting block 3 on the side. The connection between the support frame 2 and the base frame 1 is located at the first end of the support frame 2, and the second end of the support frame 2 can overlap the second end of the top of the base frame 2, and the support frame 2 is in a horizontal state when overlapped.

[0018] Connecting block 3 extends downwards to below support frame 2, and a connector 4 is hinged at the bottom. The bottom end of connector 4 is connected to the top end of telescopic mechanism 5. The bottom end of telescopic mechanism 5 is rotatably connected to base frame 1. When telescopic mechanism 5 extends, it can tilt support frame 2. Preferably, telescopic mechanism 5 is an electric cylinder. When the electric cylinder extends or retracts, it can tilt support frame 2 and the structure on support frame 2. When support frame 2 is in a horizontal state, electric cylinder retracts to its shortest state; when support frame 2 is in a vertical state, electric cylinder extends to its longest state.

[0019] like Figure 3 As shown, a screening frame 6 is installed above the support frame 2. The screening frame 6 is connected to the support frame 2 via elastic elements 7, and a vibration motor 8 is installed on the side of the screening frame 6. The elastic elements 7 are springs, numbered in four groups, with each group of springs positioned near one of the four corners of the support frame 2. The vibration motor 8 drives the screening frame 6 to vibrate.

[0020] The screening box 6 has several layers of screens 9 arranged from top to bottom, and the screen hole size of the screens 9 decreases from top to bottom to achieve graded screening.

[0021] The first end of the screening box 6 is open, and a number of discharge hoppers 10 are provided at the first end. The number of discharge hoppers 10 corresponds one-to-one with the screen 9, and their lengths decrease from top to bottom, which are used to discharge the screened Chinese medicine.

[0022] like Figure 4 As shown, a first collection box 12 is mounted on the base frame 1, located below the support frame 2, and is used to receive materials falling from the screening frame 6. Preferably, a first support block 16 is provided at the bottom of the first collection box 12, and a first sliding groove is provided on the base frame 1. When the first collection box 12 is mounted on the base frame 1, the first support block 16 engages with the first sliding groove, thus limiting the position of the first collection box 12. Simultaneously, a handle 15 is provided on the first collection box 12, facilitating pushing and pulling the first collection box 12 in and out of the base frame 1, and also facilitating the operator to lift the first collection box 12.

[0023] A connecting frame 13 is provided on one side of the base frame 1. Several second collection boxes 14, each corresponding to a discharge hopper 10, are provided on the connecting frame 13 to collect materials screened by different screens 9. Each second collection box 14 has a second support block 17 at its bottom. Several second sliding grooves 18 are evenly distributed along the length of the connecting frame 13. When the second collection box 14 is connected to the connecting frame 13, the second support blocks 17 engage with the second sliding grooves 18 to limit the position of the second collection box 14. Furthermore, the number of second sliding grooves 18 is greater than the number of second support blocks 17, allowing the position of the second collection box 14 to be adjusted by using the second support blocks 17 in conjunction with different second sliding grooves 18, thus adapting to different discharge positions when the screening frame 6 is tilted at different angles.

[0024] The second collection box 14 is equipped with a handle 15, which makes it convenient for operators to push, pull and lift the second collection box 14.

[0025] A limiting plate 19 is provided at the second end of the screening frame 6, and the limiting plate 19 extends downward to the support frame 2. When the screening frame 6 tilts at too large an angle, the screening frame 6 will move downward under the action of gravity. In order to limit its movement distance, a limiting plate 19 is provided at the second end of the screening frame 6. After the screening frame 6 moves down a certain distance, the limiting plate 19 will contact the support frame 2 to prevent the screening frame 6 from moving further down.

[0026] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
