[0030] Please refer to Figures 1 to 5 The present application provides a medicine pulverizer, including a shell 10, a feeding assembly 20 and a pulverizing assembly.

[0031] Specifically, a crushing chamber is defined inside the shell 10, a feeding port connected to the crushing chamber is provided at the bottom of the shell 10, a spacer 80 is provided inside the crushing chamber, and a filter screen 90 is provided in the spacer 80 at a position opposite to the feeding port; the feeding assembly 20 includes a feeding pipe 22 and a hopper 21, one end of the feeding pipe 22 passes through the front surface of the shell 10 and is connected to the crushing chamber, and the other end of the feeding pipe 22 is connected to the discharge port of the hopper 21; the crushing assembly includes a crushing unit and a rotating shaft 30, one end of the rotating shaft 30 passes through the rear surface of the shell 10 and extends into the crushing chamber and is connected to the crushing unit, and the crushing unit is provided in the crushing chamber. After the medicinal materials enter the crushing chamber, the rotating shaft 30 drives the crushing unit to rotate to crush the medicinal materials entering the crushing chamber so that the medicinal materials are formed into powder.

[0032] For example, the spacer can be detachably mounted in the crushing chamber, so that the spacer can be quickly removed for cleaning. In addition, the spacer is embedded with a filter screen only at the position directly opposite to the feed opening, so that the medicinal materials flow out through the filter screen 90 after being crushed in the crushing chamber, thereby ensuring that the crushed medicinal materials reach a certain degree before flowing out.

[0033] Exemplarily, the driving rotating shaft 30 can be driven by a power source, for example, the power source can be a motor, which drives the rotating shaft 30 to rotate. Since the rotating shaft 30 is connected to the crushing unit, the crushing unit rotates in the crushing chamber, thereby crushing the medicinal materials entering the crushing chamber to form powder.

[0034] The drug pulverizer based on the above technical features puts the medicinal materials to be crushed into the feed hopper 21, and enters the crushing chamber through the feed pipe 22, and then drives the rotating shaft 30 to rotate, so that the crushing unit is driven to rotate in the crushing chamber to crush the medicinal materials in the crushing chamber, until the medicinal materials are crushed into powder and then fall from the filter screen 90 to the container at the discharge port for storage. It has a simple structure and is easy to operate. It can ensure that the medicinal materials will not flow out until they are crushed to a certain coarseness. It has a good crushing effect and does not require manual operation, which is conducive to reducing labor intensity.

[0035] In a possible embodiment, the crushing unit includes a cutter disc 110 and a cutter disc frame 100. The cutter disc frame 100 is disposed in the crushing chamber, and the cutter disc frame 100 is connected to the end of the rotating shaft 30 extending into the crushing chamber, and the cutter disc 110 is installed on the cutter disc frame 100.

[0036] For example, since the cutter head frame 100 is connected to the end of the rotating shaft 30, the cutter head frame 100 can be driven to rotate while the rotating shaft 30 rotates, thereby driving the cutter head 110 installed on the cutter head frame 100 to rotate, thereby achieving the crushing of the medicinal materials in the crushing chamber.

[0037] In a possible implementation, a mounting hole 101a is provided in the middle of the cutter head frame 100, and the end of the rotating shaft 30 extending into the pulverizing chamber is engaged with the mounting hole 101a. In this way, the cutter head frame 100 can be quickly mounted on the rotating shaft 30, which facilitates the subsequent disassembly and assembly of the cutter head frame 100.

[0038] In a possible embodiment, the cutter disc holder 100 includes a disc body 101 and a plurality of outwardly extending fixing strips 102, wherein the plurality of fixing strips 102 are distributed along the circumferential direction of the disc body 101, and each fixing strip 102 is provided with a clamping position 102a, and the cutter disc 110 extends into the clamping position 102a for clamping, so that the cutter disc 110 is installed on the cutter disc holder 100.

[0039] In a possible implementation, a driving member 40 is further included, the output end of the driving member 40 is connected to a driving wheel 50 , one end of the rotating shaft 30 extending into the outside of the crushing chamber is connected to a driven wheel 60 , and the driven wheel 60 is connected to the driving wheel 50 via a transmission belt 70 .

[0040] In a possible embodiment, a cover is further included, which is disposed on the top of the hopper 21 to cover the inside of the hopper 21. In this way, by sealing the top of the hopper 21 with the cover, it is possible to effectively prevent foreign matter from entering the hopper 21, causing the medicinal materials to be mixed with other impurities and affecting the purity of the medicine.

[0041] In a possible embodiment, the shell 10 has a first opening and a second opening on its opposite front and rear surfaces, respectively. The front cover and the rear cover are removable at the first opening and the second opening, respectively. The front cover is provided with a first inlet for the rotating shaft 30 to pass through, and the rear cover is provided with a second inlet for connecting the crushing chamber and the feed pipe 22.

[0042] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should belong to the scope covered by the claims of the utility model.
