[0026] In this embodiment, reference Figure 1 , Figure 2 , Figure 3 and Figure 4The multi-stage crushing and screening structure 2 includes a connecting box 201, which is connected to the end face of the connecting platform 1.

[0027] Based on the above structure and its connection relationships, the controller 3 controls the drive motor 204 to operate. When the drive end of the drive motor 204 rotates, it sequentially drives the drive rod 205, drive helical gear 206, driven helical gear 207, connecting helical gear 208, driven rod 209, and primary crushing roller 210 to rotate. When the primary crushing roller 210 rotates, the material is crushed in the first stage. The crushed material falls onto the filter screen 221. At this time, when the driven rod 209 rotates, it drives the rotating plate 218 to rotate. When the rotating plate 218 rotates, it drives the lifting connecting plate 219 and the connecting connecting rod 220 under the action of the connecting spring 222. The filter screen 221 moves up and down to screen materials. The refined material is discharged from the mesh of the filter screen 221, passes through the material guide plate 223 and is discharged from the refined material outlet. The uncrushed material is introduced into the inner cavity of the secondary crushing box 203 from the outlet on the filter screen 221. At the same time, when the connecting helical gear 208 rotates, it sequentially drives the connecting rod 211, the connecting helical gear 212, the rotating helical gear 213, the transmission helical gear 214, the rotating rod 215, the transmission rod 216 and the secondary crushing roller 217 to rotate, so that the uncrushed material is crushed a second time by the secondary crushing roller 217 and discharged from the refined material outlet at the bottom of the secondary crushing box 203.
[0028] Furthermore, the drive motor 204 is connected to the controller 3 via wires in an electrical connection manner, and the operation of the drive motor 204 can be controlled by the controller 3.
[0029] Furthermore, the drive rod 205 is connected to the side wall of the primary crushing chamber 202 via a bearing seat, wherein the drive rod 205 and the bearing seat are rotatably connected. The driven rod 209 is connected to the side wall of the primary crushing chamber 202 via a bearing seat, wherein the driven rod 209 and the bearing seat are rotatably connected. The connecting rod 211 is connected to the end face of the connecting platform 1 via a bearing seat, wherein the connecting rod 211 and the bearing seat are rotatably connected. The rotating rod 215 is connected to the side wall of the secondary crushing chamber 203 via a bearing seat, wherein the rotating rod 215 and the bearing seat are rotatably connected. The transmission rod 216 is connected to the side wall of the secondary crushing chamber 203 via a bearing seat. On the side wall of the multi-stage crushing chamber 203, the transmission rod 216 is rotatably connected to the bearing seat. On the side wall of the connecting chamber 201, a sliding groove is provided corresponding to the connecting rod 220. The connecting rod 220 is slidably connected to the sliding groove. A discharge port is provided in the middle of the filter screen 221. A feed port is provided on the end face of the first-stage crushing chamber 202. Fine material outlets are provided at the bottom of the connecting chamber 201 and at the tail end of the material guide plate 223, and at the bottom of the second-stage crushing chamber 203. Through the interaction between the various components in the multi-stage crushing and screening structure 2, the multi-stage crushing and screening structure 2 can operate smoothly during use.
[0030] The working process of this utility model is as follows: When using the multi-stage pulverizer for pharmaceutical raw materials, first connect the power supply to the device to put it into operation. Then, the controller 3 controls the drive motor 204 to run. When the drive end of the drive motor 204 rotates, it sequentially drives the drive rod 205, drive helical gear 206, driven helical gear 207, connecting helical gear 208, driven rod 209, and primary pulverizing roller 210 to rotate. When the primary pulverizing roller 210 rotates, the material is pulverized in the first stage. The pulverized material falls onto the filter screen 221. At this time, when the driven rod 209 rotates, it drives the rotating plate 218 to rotate. When the rotating plate 218 rotates, it passes through the lifting connecting plate 219 and the connecting rod 220 and the connecting spring 222. Under the action of the filter screen 221, the filter screen 221 moves up and down repeatedly to screen the material. The fine material is discharged from the mesh of the filter screen 221, passes through the material guide plate 223 and is discharged from the fine material outlet. The uncrushed material is introduced into the inner cavity of the secondary crushing box 203 from the outlet on the filter screen 221. At the same time, when the connecting helical gear 208 rotates, it drives the connecting rod 211, the connecting helical gear 212, the rotating helical gear 213, the transmission helical gear 214, the rotating rod 215, the transmission rod 216 and the secondary crushing roller 217 to rotate in sequence. This causes the uncrushed material to be crushed a second time by the secondary crushing roller 217 and discharged from the fine material outlet at the bottom of the secondary crushing box 203, thus completing the crushing work of the material.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
