The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0022] Next, the embodiments of the present utility model will be described according to its overall structure.

[0023] A raw material crusher for processing granular pharmaceuticals, as Figures 1-4As shown in the figure, it includes a crushing component 100. The crushing component 100 includes a crushing barrel 110. Inside the crushing barrel 110, there is a screening component 200. Below the screening component 200, there is a cleaning component 300 slidably connected to the inner wall of the crushing barrel 110. The screening component 200 includes a servo motor 210 fixedly connected to the top end of the crushing barrel 110. The output end of the servo motor 210 is fixedly connected with a worm 220. On both sides of the worm 220, there are meshing worm wheels 230. At the central position of the worm wheel 230, there is a rotating shaft 240 fixedly connected. One end of the rotating shaft 240 away from the worm wheel 230 is fixedly connected with a cam 250. Below the cam 250, there is a screen 260. One side of the bottom end of the screen 260 is fixedly connected with multiple groups of springs 270. And one end of the screen 260 away from the springs 270 is rotatably connected with a rotating shaft 280. On one side of the crushing barrel 110, there is a conveying pipe 290 fixedly connected. At the bottom end of the inner wall of the conveying pipe 290, there is an electronic fan 2910. Above the electronic fan 2910, there is a ventilation plate 2920 fixedly connected to the inner wall of the conveying pipe 290.

[0024] Start the servo motor 210 to drive the worm 220 to rotate. The worm 220 drives the two worm wheels 230 on both sides to rotate. The worm wheels 230 drive the rotating shaft 240 to rotate. The rotating shaft 240 drives the cam 250 to rotate, causing the cam 250 to repeatedly strike the screen 260. The screen 260 vibrates under the action of the springs 270 and the rotating shaft 280, enabling the crushed particles to fall better. And some larger particles move towards the opening groove 114 side through the vibration of the screen 260 and enter the conveying pipe 290. The electronic fan 2910 sends the larger particles from the conveying pipe 290 back into the feeding port 112 for secondary crushing. While effectively screening the particle size, it can also perform secondary crushing on the larger particles, further improving the quality of the raw material during crushing.

[0025] Please refer specifically to Figure 2 and Figure 4 As shown in the figure, the cleaning component 300 includes a reciprocating lead screw 310 rotatably connected to the inner wall of the worm 220. The bottom end of the reciprocating lead screw 310 is fixedly connected with a connecting block 320. One side of the connecting block 320 is fixedly connected with a scraper 330. On both sides of the inner wall of the scraper 330, there are connecting shafts 340 welded. One end of the two connecting shafts 340 away from the scraper 330 is welded with a cross bar 350. One end of the cross bar 350 away from the connecting shaft 340 is fixedly connected with a connecting sleeve 360. Inside the connecting sleeve 360, there is a large pitch threaded rod 370 rotatably connected. At the lower end of the surface of the large pitch threaded rod 370, there is an auger 380 fixedly connected.

[0026] The crushed particles fall from inside the sieve 260. While the worm 220 rotates, it drives the reciprocating lead screw 310 to descend. The reciprocating lead screw 310 drives the scraper 330 to descend along the inner wall of the crushing barrel 110 through the connecting block 320, effectively cleaning the particles adhering to the inner wall of the crushing barrel 110, further increasing the output of particle powder. At the same time, while the scraper 330 descends, it drives the connecting sleeve 360 to descend synchronously through the connecting shaft 340 and the cross bar 350. The connecting sleeve 360 drives the large pitch threaded rod 370 to rotate, and the large pitch threaded rod 370 drives the auger 380 to rotate, enabling the auger 380 to better convey the processed particles and avoiding blockage of the discharge port 130 by a large number of particles, ensuring normal feeding.

[0027] Please refer specifically to Figure 2 and Figure 3 Four sets of support legs 111 are fixedly connected to the lower end of the surface of the crushing barrel 110.

Crushing rollers 120 are fixedly connected to the surfaces of two sets of rotating shafts 240. An opening groove 114 is formed on one side of the crushing barrel 110, and the opening groove 114 is at the same horizontal position as the sieve 260.

[0028] The staff puts the raw materials into the feed inlet 112, and the raw materials are crushed by the crushing rollers 120. The protective cover 113 can effectively prevent particle splashing during the crushing of the raw materials.

[0029] Please refer specifically to Figure 2 and Figure 4 A limiting slider 331 is welded to the side of the scraper 330 away from the connecting shaft 340, and the scraper 330 is slidably connected to the inner wall of the crushing barrel 110.

[0030] The scraper 330 can better clean the particles on the inner wall of the crushing barrel 110. By setting the limiting slider 331, the rotation of the scraper 330 can be effectively prevented.

[0031] In use, the staff puts raw materials into the feeding port 112, starts the servo motor 210 to drive the worm 220 to rotate. The worm 220 drives the two-sided worm wheels 230 to rotate, and the worm wheels 230 drive the rotating shaft 240 to rotate. The rotating shaft 240 drives the crushing roller 120 to crush the raw materials. The protective cover 113 can effectively prevent particle splashing during the process of processing the raw materials of vermicelli. The rotating shaft 240 drives the cam 250 to rotate, so that the cam 250 repeatedly knocks on the sieve mesh 260. The sieve mesh 260 vibrates under the action of the spring 270 and the rotating shaft 280, enabling the crushed particles to fall better. Some larger particles move to the side of the opening groove 114 through the vibration of the sieve mesh 260 and enter the conveying pipe 290. The electronic fan 2910 sends the larger particles from the conveying pipe 290 back into the feeding port 112 for secondary crushing. While effectively screening the particle size, it can also perform secondary crushing on the larger particles, further improving the quality of the raw materials during crushing. The crushed particles fall from the sieve mesh 260. While the worm 220 rotates, it drives the reciprocating screw rod 310 to descend. The reciprocating screw rod 310 drives the scraper 330 to descend along the inner wall of the crushing barrel 110 through the connecting block 320, effectively cleaning the particles adhering to the inner wall of the crushing barrel 110 and further increasing the output of the particle powder. At the same time, when the scraper 330 descends, it drives the connecting sleeve 360 to descend synchronously through the connecting shaft 340 and the cross bar 350. The connecting sleeve 360 drives the large pitch screw rod 370 to rotate, and the large pitch screw rod 370 drives the auger 380 to rotate, enabling the auger 380 to better convey the processed particles and avoiding blockage of the discharge port 130 by a large number of particles, ensuring normal feeding. The parts not involved in this device are the same as or can be implemented using the prior art.
