[0015] 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.

[0016] The rotational connection described in this device refers to the process of baking the bearing on the shaft, providing a spring retaining ring groove on the shaft or the shaft hole, and clamping the elastic retaining ring in the retaining ring groove to achieve axial fixation of the bearing and realize rotation; the articulation refers to a connection method that is active on connecting parts such as hinges, pins and short shafts.

[0017] The present invention will be described in detail below with reference to the accompanying drawings.

[0018] Embodiment 1:

[0019] The following is combined with Figure 1-3 The present embodiment describes a grinding machine, comprising: a grinding cylinder 1, a core rod 2 and a filter plate 3 are arranged in the grinding cylinder 1, a plurality of filter plates 3 are connected to the core rod 2, the filter plates 3 are in contact with the inner wall of the grinding cylinder 1, a lifting mechanism 4 can drive the core rod 2 to lift and lower, a steel ball 5 is arranged on the filter plate 3, and the sizes of the filter holes and the steel balls 5 on different filter plates 3 decrease from top to bottom;

[0020] Solid pharmaceutical raw materials are injected into the upper part of the grinding cylinder 1, and the lifting mechanism 4 is turned on. The lifting mechanism 4 drives the core rod 2 to lift and lower. The core rod 2 drives multiple filter plates 3 and steel balls 5 to lift and lower. The raw materials enter between the steel balls 5 and are crushed by the steel balls 5 that collide with each other. They enter the lower layer through the filter holes of the filter plates 3. Since the sizes of the filter holes and steel balls 5 on different filter plates 3 decrease from top to bottom, the steel balls 5 on the lower layer crush the raw materials more finely. In this way, the grinding is completed after multi-stage crushing.

[0021] Embodiment 2:

[0022] The following is an explanation based on the first embodiment. The lifting mechanism 4 includes a bracket 41, the bracket 41 is connected to the lower part of the inner wall of the grinding cylinder 1, a ratchet plate 1 42 is connected inside the bracket 41, a ratchet plate 2 43 is buckled on the ratchet plate 1 42, the ratchet plate 2 43 is connected to the lower end of the core rod 2, and the upper end of the core rod 2 is connected to the rotation power;

[0023] The power drives the core rod 2 to rotate, and the core rod 2 drives the ratchet disk 2 43 to slide on the fixed ratchet disk 2 43. Under the reciprocating staggered and interlocking action of the ratchet teeth of the two ratchet disks, the core rod 2 drives the filter plate 3 to rotate and vibrate at the same time to complete the grinding. The power can be transmitted between the power and the core rod 2 by a slider coupling.

[0026] The power drives the ratchet plate 1 42 to rotate, and the ratchet plate 1 42 drives the ratchet plate 2 43, the core rod 2, and the filter plate 3 to slide back and forth on the slide rail 44 to complete the vibration. Although the filter plate 3 cannot rotate, the ratchet plate 1 42 can withstand a higher speed power input compared to the second embodiment, thereby increasing the vibration frequency.

[0027] The lifting mechanism 4 also includes an input shaft 45, which is rotatably connected to the wall of the grinding cylinder 1, and the input shaft 45 is connected to the ratchet plate 1 42 through a bevel gear set 46;

[0028] The power drives the input shaft 45 to rotate, and the input shaft 45 drives the ratchet plate 1 42 to rotate through the bevel gear set 46.
