Figure 1-Figure 4A crushing and grinding device for processing Chinese medicinal materials in this embodiment includes a box cabin 100, a material guide plate 200 is provided on one side of the upper end of the box cabin 100, a spinning sleeve 300 is connected to the lower inclined end of the material guide plate 200, a grinding roller 310 is matched on the inner side of the spinning sleeve 300, a first rotating shaft 320 is fixed at the axis center of the upper end of the grinding roller 310, and a second rotating shaft 340 is vertically connected to the upper end of the first rotating shaft 320 through a micro-vibration elastic connecting member 330, a motor 350 whose output end is connected to the second rotating shaft 340 is provided at the upper end of the box cabin 100, an obliquely installed vibrating screen 400 is provided on the inner side of the box cabin 100 and below the spinning sleeve 300, the lower inclined end of the vibrating screen 400 extends to the feeding end of the Jiaolong conveyor 500, and the discharging end of the Jiaolong conveyor 500 extends to the inner side of the material guide plate 200.

[0021] A feed port 110 connected to the inner side of the guide plate 200 is provided at the top of the cabin 100, and a discharge port 120 located below the vibrating screen 400 is provided at the bottom of the cabin 100. When in use, the Chinese medicinal materials that have been preliminarily crushed can be introduced into the guide plate 200 through the feed port 110, so that the materials can directly enter the grinding unit. At the same time, qualified powder after grinding will be discharged to the collection unit through the discharge port 120.

[0022] The micro-vibration elastic connecting member 330 includes a bottom plate 3301 fixed to the upper end of the first rotating shaft 320, a top plate 3302 fixed to the bottom of the second rotating shaft 340 and parallel to the bottom plate 3301, a guide column 3303 vertically fixed to the upper end of the bottom plate 3301 and slidably arranged on the top plate 3302, a limit block 3304 fixed to the top of the guide column 3303, a spring 3305 sleeved on the outer side of the guide column 3303 and with one end abutting against the limit block 3304 and the other end abutting against the top plate 3302, and an exciter 3306 arranged on the bottom plate 3301. When grinding the medicinal material, the motor 350 will drive the first rotating shaft 320, the micro-vibration elastic connecting member 3301, and the micro-vibration elastic connecting member 3302 to move. The connecting piece 330, the second rotating shaft 340 and the grinding roller 310 rotate synchronously, so that the grinding roller 310 completes the fine grinding of the material in cooperation with the spinning sleeve 300. At the same time, the bottom plate 3301 can form high-frequency micro-vibration with the second rotating shaft 340 in cooperation with the guide column 3303, the spring 3305, the top plate 3302 and the exciter 3306. In this way, the grinding roller 310 can jump up and down at the same time during the horizontal rotation process, so that the grinding teeth on the outside of the grinding roller 310 and the grinding teeth on the inside of the spinning sleeve 300 can form frequent interlacing, squeezing and micro-collision, so that the grinding surface forms an absolute pressure on the medicinal material, and the grinding and crushing effect is more thorough.

[0023] The vibrating screen 400 includes a sieve plate 410 which is obliquely arranged on the inner side of the cabin 100 and the inclined end is located below the spinning sleeve 300, spring legs 420 installed on the inner side of the cabin 100 and used to support the two ends of the bottom of the sieve plate 410, and a vibration motor 430 arranged at one end of the sieve plate 410; one side of the bottom of the Jiaolong conveyor 500 has a material guide port 510 corresponding to the lower inclined end of the sieve plate 410, and a discharge pipe 520 is arranged on one side of the upper end of the Jiaolong conveyor 500 and extends to the inner side of the material guide plate 200. In order to further improve the grinding and crushing effect of Chinese medicinal materials and prevent residual leakage, after the spinning sleeve 300 cooperates with the grinding roller 310 to perform the first wave of fine grinding on the medicinal materials, the qualified powder will be discharged together with a very small part of the large-particle material and directly fall onto the screen plate 410. At this time, the screen plate 410 can fully screen the fallen materials with the cooperation of the vibration motor 430 and the spring leg 420. The qualified materials will fall and be discharged directly, and the unqualified materials will naturally roll into the Jiaolong conveyor 500. The Jiaolong conveyor 500 can push this part of the material to the discharge pipe 520 and the guide plate 200 through the screw rod, so that the material is then ground for the second time until the material is completely ground. This avoids the shortcomings of traditional grinding devices that can usually only grind the medicinal materials once, and the grinding and screening are performed by the distribution sub-machine, and the grinding processing efficiency is further improved.

[0024] In summary, in the present embodiment, a crushing and grinding device for processing Chinese medicinal materials is introduced into the guide plate 200 through the feed port 110 during operation after the preliminary crushing of the Chinese medicinal materials, so that the materials can directly enter the grinding unit. At this time, the motor 350 will drive the first rotating shaft 320, the micro-vibration elastic connecting member 330, the second rotating shaft 340 and the grinding roller 310 to rotate synchronously. At the same time, the bottom plate 3301 can form a high-frequency micro-vibration with the cooperation of the guide column 3303, the spring 3305, the top plate 3302 and the exciter 3306, so that the grinding roller 310 can jump up and down at the same time during the horizontal rotation process, so that the grinding teeth on the outside of the grinding roller 310 and the spinning sleeve 3306 are 00 Frequent interlacing, squeezing and micro-impacting can be formed between the inner grinding teeth, so that the grinding surface forms absolute pressure and grinding on the medicinal materials. Then, after the first wave of fine grinding, the qualified powder will be discharged together with a very small part of the large-size material and fall directly onto the screen plate 410. At this time, the screen plate 410 can fully screen the fallen material with the cooperation of the vibration motor 430 and the spring leg 420. The qualified material will fall and be discharged directly, and the unqualified material will naturally roll into the Jiaolong conveyor 500. The Jiaolong conveyor 500 can push this part of the material to the discharge pipe 520 and the guide plate 200 through the screw rod, so that the material is then ground for a second cycle until the material is completely ground.
