[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a medicine pulverizer, including a pulverizing bin 1, a feeding assembly is arranged on the top of the pulverizing bin 1, a motor 3 is fixedly connected to the outer wall of the pulverizing bin 1, a driving wheel 4 is fixedly connected to the output end of the motor 3, a driven wheel 5 is rotatably connected to the inside of the pulverizing bin 1, the driving wheel 4 is meshed with the driven wheel 5, a pulverizing roller 6 is fixedly connected to the inside of the driving wheel 4 and the driven wheel 5, one end of the pulverizing roller 6 is fixedly connected to a concave wheel 7, a transmission belt 8 is arranged on the outer wall of the concave wheel 7, and a concave wheel 2 is arranged on the inner wall of the transmission belt 8 9, a worm 10 is fixedly connected inside the concave wheel 9, both ends of the worm 10 are rotatably connected inside the crushing bin 1, a support plate 11 is fixedly connected inside the crushing bin 1, a worm wheel 12 is rotatably connected to the upper surface of the support plate 11, the support plate 11 is meshed with the worm wheel 12, a kneading table 13 is fixedly connected to the upper surface of the worm wheel 12, the kneading table 13 is rotatably connected to the inside of the crushing bin 1, a crushing ring 14 is fixedly connected inside the crushing bin 1, and a feed assembly includes a feed plate 2, and the lower surface of the feed plate 2 is fixedly connected to the top of the crushing bin 1;

[0032] Specifically, first, the medicine is accurately transported to the upper side of the inner part of the crushing bin 1 through the feeding plate 2, and accurately falls on the surface of the crushing roller 6. Then, the output end of the motor 3 drives the driving wheel 4 to rotate. Due to the precise meshing between the driving wheel 4 and the driven wheel 5, the driven wheel 5 will rotate with the rotation of the driving wheel 4, ensuring the synchronous rotation of the two crushing rollers 6, providing stable power for the initial crushing of the medicine. After the medicine is initially crushed, it will naturally fall on the surface of the kneading table 13. At this time, with the continuous rotation of the crushing roller 6, the concave wheel 7 will be driven to rotate inside the crushing bin 1. Through the ingenious connection of the transmission belt 8, the rotation of the concave wheel 7 will synchronously drive the concave wheel 2 9 below to rotate, ensuring the smooth transmission of power. With the rotation of the concave wheel 2 9, the worm 10 is also driven to rotate. Due to the meshing relationship between the worm 10 and the worm wheel 12, the worm wheel 12 will rotate above the support plate 11 with the rotation of the worm 10, thereby driving The rotation of the kneading table 13 allows the medicine to move on the external thread of the outer wall of the kneading table 13, and then the medicine is carefully kneaded with the crushing ring 14 that matches the external thread of the outer wall of the kneading table 13. As the kneading table 13 continues to rotate and the medicine moves downward, the distance between the crushing ring 14 and the kneading table 13 gradually decreases, so that the crushing effect of the medicine gradually becomes more delicate. In order to ensure the stability and efficiency of the entire crushing process, an integrated sensor is cleverly arranged inside the crushing bin 1, which can monitor various parameters of the crushing process in real time, and control the motor 3 to make corresponding adjustments through data to ensure the efficiency, stability and reliability of the entire crushing process. Finally, ultrasonic assisted crushing is also integrated inside the crushing bin 1. When the ultrasonic generator is working, high-frequency vibration will be generated, and the vibration will be transmitted to the medicine through the crushing bin 1. Under the action of ultrasonic waves, the crushing effect of the medicine will be significantly improved, and the uniformity of crushing will also be significantly improved.

[0033] Reference Figure 1 , Figure 2 and Figure 4 The crushing bin 1 is slidably connected to a storage bin 15, the outer wall of the crushing bin 1 is fixedly connected to a fixed box 16, the outer wall of the fixed box 16 is provided with a filter 17, the inner part of the filter 17 is fixedly connected to a sub-button 18, the inner part of the fixed box 16 is fixedly connected to a female buckle 19, the outer wall of the sub-button 18 is slidably connected to the inner part of the female buckle 19, the inner part of the fixed box 16 is slidably connected to a dust collecting filter box 20, the inner part of the fixed box 16 is slidably connected to a slide bar 21, one end of the slide bar 21 is fixedly connected to a trapezoidal block 22, the other end of the slide bar 21 is fixedly connected to a limiting block 23, the outer wall of the slide bar 21 is sleeved with a spring 24, one end of the spring 24 is fixedly connected to the outer wall of the trapezoidal block 22, and the other end of the spring 24 is fixedly connected to the inner part of the fixed box 16;

[0034] Specifically, first, when the medicine is crushed, it will fall into the interior of the storage bin 15. During this process, the fan 25 will start to absorb the dust generated during the crushing process, and the dust will be guided to the dust filter box 20, thereby realizing the preliminary collection of the dust. When the dust inside the dust filter box 20 accumulates to a certain extent, it needs to be cleaned. At this time, the limit block 23 can be pulled to move along the slide bar 21, which will cause the trapezoidal block 22 to be pulled out from the interior of the dust filter box 20. At the same time, the spring 24 will contract. When the trapezoidal block 22 After being fully pulled out, the dust filter box 20 can be easily pulled out, making it convenient for the user to clean it. In addition, in order to protect the fan 25 from dust, a filter 17 is also equipped. The filter 17 can not only block dust from entering the fan 25, but also filter out impurities in the air to ensure the normal operation of the fan 25. When the filter 17 needs to be cleaned or replaced, the sub-buckle 18 and the main buckle 19 can be used to easily disassemble and assemble the filter 17, which not only improves the maintenance convenience of the equipment, but also extends the service life of the filter 17.

[0035] Working principle: when the drug crusher is needed, the drug is first transported to the surface of the crushing roller 6 on the upper side of the crushing bin 1 through the feed plate 2. At this time, the output end of the motor 3 drives the driving wheel 4 to rotate. Due to the meshing of the driving wheel 4 and the driven wheel 5, the driven wheel 5 rotates with the rotation of the driving wheel 4, thereby driving the two crushing rollers 6 to rotate, and the drugs are initially crushed. The crushed drugs will fall on the surface of the kneading table 13. At this time, the rotation of the crushing roller 6 will drive the concave wheel 7 to rotate inside the crushing bin 1, and then the concave wheel 2 9 below will be driven to rotate synchronously through the transmission belt 8, thereby driving the worm 10 to rotate. Due to the meshing relationship between the worm 10 and the worm wheel 12, the worm wheel 12 rotates above the support plate 11 with the rotation of the worm 10, thereby driving the kneading table 13 to rotate, and then causing the drugs to move on the external thread of the outer wall of the kneading table 13, and then cooperate with the corresponding crushing ring 14 to finely knead the drugs. The distance between the material ring 14 and the kneading table 13 is gradually reduced, so that the medicine is gradually crushed finely. An integrated sensor is also arranged inside the crushing bin 1 to realize real-time monitoring of the crushing process and control the motor 3 to make corresponding adjustments at the same time. Finally, in the process of crushing, the ultrasonic wave inside the crushing bin 1 can also be used to assist the crushing, and the crushing efficiency and uniformity can be improved by ultrasonic vibration. The crushed medicine will fall into the storage bin 15. In this process, the dust generated in the crushing process is absorbed by the fan 25 and collected by the dust filter box 20. Then, the limit block 23 is pulled to cooperate with the slide bar 21, so that the trapezoidal block 22 is pulled out of the dust filter box 20, and the spring 24 is contracted at the same time. Then the dust filter box 20 can be pulled out for cleaning, so as to achieve the effect of centralized collection of dust. Finally, the fan 25 can be protected by the filter 17 to resist the damage caused by dust to the fan 25. The filter 17 can also be disassembled and assembled by the sub-buckle 18 and the mother buckle 19.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
