[0016] 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.

[0017] Example 1 like Figures 1-5 As shown, this utility model provides a technical solution: a dust-free micro-pulverizer for pharmaceutical production, including a dustproof shell 1, with a hollowed-out bottom. A support frame 11 is fixedly installed on the outer wall of the dustproof shell 1, and a fixing rod 12 is fixedly installed inside the dustproof shell 1. A pulverizing chamber 2 is provided on the top of the dustproof shell 1, and a bottom plate 3 is provided on the bottom of the dustproof shell 1. A baffle 21 is hinged to the top of the pulverizing chamber 2, and a first motor 4 is fixedly installed on the top of the pulverizing chamber 2. A guide pipe 5 is fixedly connected to the bottom of the pulverizing chamber 2, and the bottom of the guide pipe 5 is fixedly... A protective cover 52 is connected to the bottom of the fixing rod 12, and a second motor 6 is fixedly installed. The output shaft of the second motor 6 is fixedly installed with a grinding seat 61. The protective cover 52 is sleeved on the surface of the grinding seat 61. The output shaft of the first motor 4 is fixedly connected to a mounting shaft 41. A crushing blade 42 is fixedly installed on the surface of the mounting shaft 41. The crushing blade 42 is located inside the crushing box 2. The bottom end of the guide pipe 5 extends downward into the interior of the dustproof shell 1. The guide pipe 5 is fixedly connected to the dustproof shell 1. A valve 51 is installed inside the guide pipe 5.

[0018] In this embodiment, medicine is added to the grinding chamber 2. The baffle 21 is hinged to the grinding chamber 2, which can close the baffle 21 to keep the inside of the grinding chamber 2 in a sealed environment, preventing external dust from falling into the grinding chamber 2 and contaminating the medicine. The feed pipe 5 is connected to the inside of the grinding chamber 2. The valve 51 inside the feed pipe 5 is in the closed state, which allows the medicine to be stored in the grinding chamber 2. The mounting shaft 41 is connected to the first motor 4, so that the first motor 4 drives the mounting shaft 41 to rotate, which causes the grinding blade 42 to rotate, which can grind the medicine inside the grinding chamber 2. Since the contact area between the grinding blade 42 and the medicine is small, the medicine is pre-crushed into small particles, which is convenient for subsequent grinding and improves the grinding quality.

[0019] Example 2 like Figures 1-5 As shown, the grinding seat 61 is an inverted cone shape. Four grinding blocks 62 are installed at equal intervals on the surface of the grinding seat 61. The distance between the grinding seat 61 and the protective cover 52 gradually decreases from top to bottom. A spiral conveyor blade 63 is fixedly installed on the top of the grinding seat 61. The spiral conveyor blade 63 extends into the inside of the guide pipe 5. The side of the spiral conveyor blade 63 is fitted against the inner wall of the guide pipe 5. A receiving box 31 is fixedly installed on the top of the base plate 3. A throttle 32 is fixedly connected to the bottom of the base plate 3. The surface of the receiving box 31 is provided with external threads. The outer surface of the receiving box 31 is threadedly connected to the inner wall of the dustproof shell 1.

[0020] In this embodiment, the spiral conveyor blade 63 is installed inside the guide pipe 5, so that when the second motor 6 drives the grinding seat 61 to rotate, it can drive the spiral conveyor blade 63 to rotate together, which can remove the medicine inside the guide pipe 5, so that the medicine can flow evenly to the top of the grinding seat 61, avoiding excessive accumulation of medicine at the top of the grinding seat 61 and causing blockage. Through the gap between the grinding seat 61 and the protective cover 52, the medicine slides into the gap. At the same time, the medicine is pre-crushed to prevent the medicine from being too large to flow into the gap. When the grinding seat 61 rotates, the grinding block 62 grinds the medicine, and the gap size gradually decreases, which can gradually grind the medicine particles into finer powder. The receiving box 31 can collect and store the ground medicine. The receiving box 31 is threadedly connected to the dustproof shell 1. Turning the handle 32 drives the receiving box 31 to rotate, which can remove it from the bottom of the dustproof shell 1, making it convenient to take out the crushed medicine. The entire medicine crushing process is in a closed environment, which can prevent the medicine from being contaminated by dust.

[0021] Working principle: Open the baffle 21 and put the medicine to be pulverized into the pulverizing box 2. Close the valve 51 to store the medicine inside the pulverizing box 2. Then close the baffle 21 to create a sealed environment inside the pulverizing box 2. Start the first motor 4 through the external power supply. The first motor 4 drives the pulverizing blade 42 to rotate inside the pulverizing box 2 to pulverize the medicine into fine particles. After the medicine is pulverized into fine particles, open the valve 51 to let the medicine flow into the guide pipe 5. The spiral conveyor blade 63 blocks the medicine and keeps it at the top. Start the second motor 6 to drive the grinding seat 61 and the spiral conveyor blade 63 to rotate, moving the medicine out of the guide pipe 5 so that the medicine can flow evenly to the top of the grinding seat 61. Then the medicine flows into the gap between the grinding seat 61 and the protective cover 52. The grinding block 62 rotates to grind the medicine into powder, improving the pulverization effect. The pulverized medicine falls into the receiving box 31. By turning the handle 32, the bottom plate 3 is removed downwards, making it easy to pick up the pulverized medicine.
