[0002] Traditional Chinese medicine (TCM) herbs are medicinal substances derived from natural sources, mainly from plants (such as roots, stems, and leaves) or animals and minerals in nature. They are processed to reduce toxicity or enhance efficacy. During the processing, the TCM herbs need to be pre-screened, so a coarse screening device is required.
[0003] Based on the design of the existing coarse screening equipment used in the processing of Chinese medicinal materials, there is no shielding structure at the top during the coarse screening process, which makes it easy for dust and impurities in the air to enter the interior, making it unsuitable. Therefore, its structure needs to be improved.
[0004] Now, a novel coarse screening device for use in the processing of Chinese medicinal materials is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a coarse sieving device used in the processing of Chinese medicinal materials, so as to solve the problem mentioned in the background art that the lack of a top shielding structure during sieving makes it easy for dust and impurities in the air to enter the interior.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a coarse screening device used in the processing of Chinese medicinal materials, comprising a bottom frame and a base, a connecting frame fixedly connected to the top of the bottom frame, a dustproof frame snapped onto the top of the connecting frame, a feed inlet fixedly connected to the top of the dustproof frame, a top cover snapped onto the top of the feed inlet, and a third handle fixedly connected to the top of the top cover.
[0007] As a further technical solution of this utility model, the top cover is detachable and snaps onto the top of the feed inlet.
[0008] As a further technical solution of this utility model, a guide rod is fixedly connected inside the bottom frame, a base is fixedly connected to the bottom end inside the bottom frame, a reset spring is fixedly installed at the four corners of the top of the base, a sieve frame is provided at the top of the base, and an installation block is fixedly connected to the four corners of the bottom of the sieve frame.
[0009] As a further technical solution of this utility model, a support base is fixedly connected to the right side of the base, a receiving box is placed inside the front end of the base, and a first handle is fixedly connected to the front end of the receiving box.
[0010] As a further technical solution of this utility model, a drive motor is fixedly installed at the top of the support base, and an eccentric wheel is fixedly connected to the output end of the drive motor.
[0011] As a further technical solution of this utility model, the guide rods are provided in two sets, and the guide rods are symmetrically distributed at the front end and rear end inside the bottom frame.
[0012] As a further technical solution of this utility model, a fixing block is fixedly connected to the top end of the reset spring, and the mounting block is snapped into the interior of the fixing block and embedded in the interior of the reset spring.
[0013] As a further technical solution of this utility model, the front end and rear end of the screen frame are respectively fixedly connected to sliders, the top end of the slider is fixedly connected to a second handle, the slider is snapped onto the outside of the guide rod and can slide, and the slider is detachable between the mounting block and the fixing block.
[0014] Compared with the prior art, the beneficial effects of this utility model are: the coarse sieve equipment used in the processing of Chinese medicinal materials not only facilitates dust prevention and avoids dust falling into the sieve frame during sieving, but also facilitates the quick installation and replacement of the sieve frame, and achieves stability during sieving;
[0015] The system is equipped with a connecting frame, a dustproof frame, a feed inlet, a top cover, and a third handle. The dustproof frame is attached to the top of the connecting frame, the feed inlet is fixedly connected to the top of the dustproof frame, the top cover is attached to the top of the feed inlet, and the third handle is fixedly connected to the top of the top cover. The top cover is detachably attached to the top of the feed inlet. The third handle opens the top cover, allowing the Chinese medicinal materials to be placed into the sieve frame through the feed inlet. After that, the top cover is closed, making it difficult for dust to enter the sieve frame during the sieving process.
[0016] With a screen frame, a fixing block, and an installation block, the screen frame can be lifted upwards using the second handle when it needs to be disassembled and replaced. At this time, the installation block can be detached from the inside of the fixing block, and the slider will detach from the guide rod, making the replacement and installation more convenient and easy.

When the eccentric wheel 6 rotates and touches the sieve frame 10, it can cause one side of the sieve frame 10 to vibrate. At this time, the slider 13 at the front end of the sieve frame 10 will slide on the guide rod 5, and the return spring 9 at the bottom will move. When the sieve frame 10 vibrates, impurities mixed in with the Chinese medicinal materials inside can be screened out, making the sieving more stable. Finally, when it is necessary to disassemble and replace the sieve frame 10, the second handle 14 is used to lift the sieve frame 10 upward. At this time, the mounting block 12 can be detached from the inside of the fixing block 11, and the slider 13 will detach from the guide rod 5, making the replacement and installation more convenient and easy.
