Detailed Implementation

[0027] 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.

[0028] Example 1: Please refer to Figures 1-6 Existing multi-stage grinding devices for drug particles are not conducive to improving the grinding effect during grinding. In order to solve this technical problem, this embodiment discloses the following technical content;

[0029] The top front end of the mounting frame 1 is equipped with a first grinding mechanism. The first grinding mechanism is composed of an automatic telescopic rod 3, a first motor 4, a grinding ball 5, a first storage box 6, and a discharge port 7. The automatic telescopic rod 3 is fixedly connected to the middle of the front side of the upper end of the mounting frame 1, and the output end of the automatic telescopic rod 3 is fixedly connected to the first motor 4. The output shaft of the first motor 4 is fixedly connected to the grinding ball 5 by bolts. The first storage box 6 is provided on the outside of the grinding ball 5. The first storage box 6 is installed on the inner side of the top of the bracket 8. The discharge port 7 is fixedly connected to the middle of the bottom end of the first storage box 6. The left and right sides of the upper end of the mounting frame 1 are fixedly connected to the diagonal rod 2 by bolts. The rear end of the upper surface of the mounting frame 1 is fixedly connected to the bracket 8.

[0030] First, the output end of the automatic telescopic rod 3 moves upward to the top with the first motor 4 and the grinding ball 5. The medicine is placed on the outer end of the upper surface of the grinding ball 5. Since there is a small distance between the outer side of the grinding ball 5 and the inner side of the first storage box 6, after the automatic telescopic rod 3 is started, the output end of the automatic telescopic rod 3 moves downward with the first motor 4 and the grinding ball 5. The first motor 4 is started, and the output shaft of the first motor 4 rotates the grinding ball 5, so that the outer side of the grinding ball 5 grinds the medicine particles with the inner side of the first storage box 6. The medicine particles that have undergone the first grinding are discharged from the discharge port 7 and fall into the 18 below for the second grinding. Multiple grindings are performed to improve the grinding effect and ensure that the medicine particles are fully ground.

[0031] Example 2: Existing multi-stage grinding devices for drug particles are inconvenient to disassemble during maintenance, and detachable components are difficult to limit. Therefore, this example uses the following technical solution, such as... Figures 1-6 As shown;

[0032] The bracket 8 has storage slots 9 on both the left and right sides of its front interior. A second grinding mechanism is mounted on the bracket 8. This second grinding mechanism consists of a storage plate 10, a second motor 11, a connecting plate 12, a grinding plate 13, a turntable 14, a vertical rod 15, a storage platform 16, an annular groove 17, a second storage box 18, and a connecting groove 19. The left and right ends of the storage plate 10 are slidably connected to the storage slots 9. The second motor 11 is fixedly connected to the center of the lower surface of the storage plate 10. The output shaft of the second motor 11 is fixedly connected to the connecting plate 12 by several bolts. A grinding plate 13 is fixedly connected to the outer end, and a connecting plate 12 is fixedly connected to the inner side of the turntable 14. Several vertical rods 15 are fixedly connected at equal angles to the outer end of the lower surface of the turntable 14. The bottom end of the vertical rods 15 is slidably connected to the annular groove 17 opened at the outer end of the upper surface of the shelf 16. A second shelf box 18 is connected to the inner side of the top of the shelf 16. Several connecting grooves 19 are opened at equal angles on the outer side of the lower end of the second shelf box 18. The lower surface of the grinding plate 13 is in contact with the inner bottom surface of the second shelf box 18. The connecting grooves 19 are slidably connected to the inner end of the top of the shelf 16.

[0033] The drug granules, after the first grinding, fall from the discharge port 7 into the second storage box 18. The turntable 14 is placed above the second storage box 18, so that the bottom end of the vertical rod 15 is positioned within the annular groove 17. The storage plate 10 is then slid to the inner rear end of the storage groove 9. The output shaft of the second motor 11 is bolted to the connecting plate 12. The second motor 11 is then started, and its output shaft rotates the connecting plate 12. Since the connecting plate 12 is fixedly connected to the inside of the turntable 14, the turntable 14, carrying the vertical rod 15, rotates within the storage box 18. When the platform 16 moves, the bottom end of the vertical rod 15 is slidably connected in the annular groove 17. When the turntable 14 rotates, the position of the turntable 14 will not shift. When the turntable 14 rotates, the grinding plate 13 grinds the drug powder in the second storage box 18 for the second time until the drug particles are fully ground. During the second grinding, since the connecting groove 19 on the outside of the second storage box 18 is slidably connected to the block at the top inner end of the platform 16, the second storage box 18 will not be rotated by the grinding plate 13, thus limiting the second storage box 18.

[0034] After grinding is complete, the ground medicine needs to be removed. Remove the bolts on the output shaft of the second motor 11, move the storage plate 10 out of the storage slot 9, remove the turntable 14 from the storage platform 16, and then remove the second storage box 18. Pour out the medicine powder in the second storage box 18 to complete the multi-stage grinding of the medicine particles.

[0035] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
