The inner wall of the rotating shaft 3 passes through and is slidably connected with the pressing column 8. The inner wall of the top end of the rotating shaft 3 is provided with a notch corresponding to the pressing column 8. A block is arranged in the notch. The friction between the block and the pressing column 8 at the sliding part is large. Manual pressing is required to make the pressing column 8 slide downward. The movement of the pressing column 8 will not be affected by the gravity of the traditional Chinese medicine material. The inner wall of the loading barrel 2 is slidably connected with the auxiliary barrel 11. The inner wall of the loading barrel 2 is provided with a slide groove, which can allow the auxiliary barrel 11 to slide up and down. The loading barrel 2 and the auxiliary barrel 11 constitute the entire grinding device. The top of the auxiliary barrel 11 is provided with a barrel cover 12. The rotating shaft 3 passes through and rotates on the inner wall of the loading barrel 2. The connecting knife column 6 is plugged into the inner wall of the bottom end of the sleeve 7. The connecting knife column 6 passes through and is plugged into the inner wall of the grinding knife 5.

[0032] Reference Figure 1 and Figure 5 A circular groove 13 is provided on the outer wall of the right end of the charging barrel 2, and the circular groove 13 is divided into upper and lower ends on the charging barrel 2. The inner wall of the left end of the attached barrel 11 is elastically connected with a cylindrical block 15 through a reset spring 14. The inner wall of the left end of the attached barrel 11 is fixedly connected to one end of the reset spring 14. When the cylindrical block 15 moves to the left, the reset spring 14 is compressed. When resetting, the elastic force of the reset spring 14 is used to reset the cylindrical block 15, so that the cylindrical block 15 returns to its initial state. The other end of the reset spring 14 is fixedly connected to the left end of the cylindrical block 15, and the cylindrical block 15 is slidably connected to the inner wall of the attached barrel 11, and the cylindrical block 15 is clamped on the inner wall of the circular groove 13.

[0033] The rotating shaft 3 penetrates through and rotates on the inner wall of the charging barrel 2 , the connecting knife column 6 is inserted into the inner wall of the bottom end of the sleeve 7 , and the connecting knife column 6 penetrates through and is inserted into the inner wall of the grinding knife 5 .

[0034] Reference Figure 3-Figure 4The limiting mechanism includes an inclined block 10, the middle part of the top of the inclined block 10 is set as an inclined surface, and the pressing column 8 squeezes the top inclined surface to make it move to the right. The top of the inclined block 10 is set as an inclined surface, so that when the sleeve 7 is plugged into the rotating shaft 3, the sleeve 7 squeezes the top inclined surface of the inclined block 10 to make the inclined block 10 move to the right. The inclined block 10 is slidably connected to the inner wall of the rotating shaft 3. The left end side wall of the inclined block 10 is elastically connected to the rotating shaft 3 through the positioning spring 9. The pressing column 8 contacts the top of the inclined block 10. The inclined block 10 is plugged into the inner wall of the sleeve 7. The inner wall of the sleeve 7 is provided with a notch corresponding to the inclined block 10, which can meet the plug-in requirements of the inclined block 10. The pressing column 8 penetrates and contacts the sleeve On the inner wall of the tube 7, a notch corresponding to the pressing column 8 is provided on the sleeve 7, which can meet the requirements of the insertion of the pressing column 8 and the sleeve 7. The left end side wall of the inclined block 10 is fixedly connected to one end of the positioning spring 9. When the inclined block 10 moves to the right, it will compress the positioning spring 9. When resetting, the elastic force of the positioning spring 9 is used to reset the inclined block 10. The other end of the positioning spring 9 is fixedly connected to the inner wall of the left end of the rotating shaft 3. The positioning spring 9 has a large elastic force and will not be easily compressed. It needs to be compressed by artificial force. The bottom end of the sleeve 7 is provided with a notch corresponding to the connecting knife column 6, which allows the connecting knife column 6 to be inserted into the bottom end notch of the sleeve 7 to preliminarily position the sleeve 7.

[0035] Working principle: First, when the grinding knife 5 needs to be disassembled and assembled, just press the pressing column 8 downward to make the pressing column 8 slide downward to squeeze the top middle inclined surface of the inclined block 10, so that the inclined block 10 moves to the left and squeezes the positioning spring 9 into a compressed state, so that the right end of the inclined block 10 is separated from the inner wall groove of the sleeve 7. At this time, hold the grinding knife 5 with your hand and drive the sleeve 7 to lift up, so that the grinding knife 5 is separated from the rotating shaft 3, the connecting knife column 6 and the pressing column 8. While separating, release the pressing column 8, and let the inclined block 10 move to the right and reset under the reverse elastic force of the positioning spring 9, and the top middle inclined surface of the inclined block 10 slowly squeezes the pressing column 8 back to the initial position, thereby realizing the disassembly of the grinding knife 5.

[0036] When the grinding knife 5 and the sleeve 7 need to be installed, the grinding knife 5 is first plugged into the rotating shaft 3 and the knife connecting column 6 to preliminarily position the grinding knife 5, and then the sleeve 7 is correspondingly plugged into the rotating shaft 3, the knife connecting column 6 and the pressing column 8, so that the bottom end of the sleeve 7 covers the grinding knife 5. At the same time, when the sleeve 7 and the outer wall of the rotating shaft 3 are plugged in, the bottom end of the sleeve 7 will squeeze the top inclined surface of the inclined block 10, so that the inclined block 10 moves to the left and compresses the positioning spring 9. When the inner wall notch of the sleeve 7 and the inclined block 10 coincide, the reverse elastic force of the positioning spring 9 is used to drive the inclined block 10 to plug into the outer wall notch of the rotating shaft 3, and the installation of the entire grinding knife 5 and the sleeve 7 is completed without using tools to twist the bolts multiple times.

[0037] When it is necessary to adjust the loading space of the charging barrel 2, just press the cylindrical block 15 with the tip of the index finger to make the cylindrical block 15 enter the inner wall of the attached barrel 11, and separate the cylindrical block 15 from the upper circular groove 13 of the charging barrel 2. At this time, the return spring 14 is in a compressed state. Then press the attached barrel 11 downward and release the cylindrical block 15 by hand, so that the attached barrel 11 slides along the inner wall of the charging barrel 2 with the cylindrical block 15, and use the inner wall of the charging barrel 2 to block the cylindrical block 15. When the cylindrical block 15 coincides with the inner wall of the circular groove 13 at the lower end of the charging barrel 2, the cylindrical block 15 moves to the right under the elastic action of the return spring 14, so that the cylindrical block 15 is plugged into the lower circular groove 13 of the charging barrel 2, completing the limitation of the attached barrel 11. If the loading space of the charging barrel 2 is to be expanded, just follow the above steps to plug the cylindrical block 15 into the upper circular groove 13 of the charging barrel 2.
