[0034] As Figures 1-2 and Figures 4-6As shown in the figure, the powder suction and collection mechanism 8 includes a suction pipe 801 fixedly connected to the top end of the filter screen plate 6. The inside of the suction pipe 801 is communicated with the bottom of the filter screen plate 6. An air extraction pump 802 is installed at the top end of the mixing box 1. The top end of the suction pipe 801 penetrates through the inner wall of the mixing box 1 and is fixedly connected to the bottom end of the air extraction pump 802. A material guiding pipe 803 is fixedly connected between the placement frame 7 and the top end of the air extraction pump 802. The inside of the material guiding pipe 803 is communicated with the inside of the placement frame 7. A drawer box 804 is slidably connected inside the placement frame 7. A knocking and vibrating mechanism 9 is installed between the inside of the suction pipe 801 and the top end of the filter screen plate 6. The bottom end of the material guiding pipe 803 is flush with the top end of the drawer box 804. The inside of the material guiding pipe 803 is communicated with the inside of the drawer box 804. A pair of sliding magnet long blocks 8041 are fixedly connected to the bottom end of the drawer box 804. A pair of sliding grooves 8042 are dug on the inner bottom end of the placement frame 7. The pair of sliding magnet long blocks 8041 are respectively located inside the pair of sliding grooves 8042 and are slidably connected to them. Fixed magnet blocks 8043 are embedded and installed on the front inner walls of the pair of sliding grooves 8042. The ends of the sliding magnet long blocks 8041 close to the fixed magnet blocks 8043 are attracted to each other. The knocking and vibrating mechanism 9 includes a round rod 901. The left and right ends of the round rod 901 are rotatably connected to the outer wall of the suction pipe 801 through bearings. An air-guided rotating fan blade 902 is sleeved on the outer wall of the round rod 901 and is located inside the suction pipe 801. The left and right ends of the round rod 901 are fixedly connected with telescopic rods 903. The ends of the pair of telescopic rods 903 away from each other are fixedly connected with knocking blocks 904. Springs 905 are sleeved on the outer walls of the pair of telescopic rods 903. The two ends of the springs 905 are respectively fixedly connected to the knocking blocks 904 and the outer walls of the telescopic rods 903. The bottom end of the knocking block 904 at the bottom is in contact with the top end of the filter screen plate 6.

[0035] Beneficial effects: The air extraction pump 802 extracts the powdery medicinal materials inside the mixing box 1 upward through the suction pipe 801, and they fall into the drawer box 804 through the material guiding pipe 803 for collection. After the collection is completed, the drawer box 804 is pulled backward to separate the sliding magnet long block 8041 from the fixed magnet block 8043, canceling the connection and fixation between the drawer box 804 and the placement frame 7, and the drawer box 804 can be driven for discharging, so as to facilitate the collection of the powdery medicinal materials for subsequent utilization, avoid the powdery medicinal materials from spreading out to the surrounding areas when the mixing box 1 is opened later, reduce the cleaning burden of the staff, and also reduce the waste of Chinese herbal medicine resources. Moreover, during the upward flow of the gas, the air guide rotating fan blades 902 are continuously blown, causing them to rotate slowly, and driving a pair of telescopic rods 903 to rotate. When the pair of knocking blocks 904 rotate downward, through the elastic telescopic action of the telescopic rods 903 and the springs 905, the filter screen plate 6 is alternately knocked to generate vibration, shaking off the broken medicine materials blocked and attached to the bottom end of the filter screen plate 6. At the same time, since the pair of feeding thick pipes 3 are connected to the filter screen plate 6, the vibration effect will also be transmitted to the pair of feeding thick pipes 3, shaking off the broken medicinal materials attached to their inner walls, ensuring the full utilization of Chinese herbal medicines.

[0036] Working principle: First, various large pieces of Chinese herbal medicines enter a pair of feeding thick pipes 3 respectively. At this time, the left output end of the double-shaft motor 4 drives the second rotating rod 505 at the front side to rotate through the transmission between a pair of belt pulleys 503 and a transmission belt 504. The second rotating rod 505 at the front side then drives the second rotating rod 505 at the rear side to move in opposite directions through the meshing of two gears 507, causing a pair of crushing rollers 506 inside the pair of feeding thick pipes 3 to rotate in opposite directions, and crushing various Chinese herbal medicines falling between them, breaking the large pieces of Chinese herbal medicines into multiple small pieces of Chinese herbal medicines. Then, they enter the mixing box 1 through the feeding thick pipes 3. The right output end of the double-shaft motor 4 drives the first rotating rod 501 to rotate, which drives multiple pairs of stirring rods 502 to rotate, stirring the various crushed medicinal materials that have fallen, and mixing the various crushed medicinal materials together. At this time, the air extraction pump 802 extracts the powdered medicinal materials diffused due to stirring inside the mixing box 1 upward through the suction pipe 801 and into the suction pipe 801. The filter mesh plate 6 blocks the crushed medicinal materials and only allows the powdered medicinal materials to pass through. The air-conducting rotating fan blades 902 inside the suction pipe 801 also rotate under the continuous blowing of the gas, driving the round rod 901 to rotate, causing the round rod 901 to drive a pair of telescopic rods 903 and the knocking block 904 to rotate. And when the knocking block 904 rotates to the bottom, it approaches the top of the filter mesh plate 6, and under the elastic telescopic action of the telescopic rod 903 and the spring 905, it contracts upward, maintaining contact and collision with the filter mesh plate 6, realizing the alternate knocking of the filter mesh plate 6, generating vibration, shaking off the crushed medicinal materials blocked and attached to the bottom end of the filter mesh plate 6. At the same time, the crushed medicinal materials attached to the inner walls of the pair of feeding thick pipes 3 will also fall due to the vibration effect, ensuring the full utilization of Chinese herbal medicines. Immediately afterwards, the powdered medicinal materials fall into the drawer box 804 through the guide pipe 803 for collection. After the mixing of various crushed medicinal materials is completed, the sealing door 2 is opened to collect the mixed medicinal materials inside the mixing box 1. Then, the drawer box 804 is pulled backward, separating the sliding magnet long block 8041 from the fixed magnet block 8043, driving the drawer box 804 to be pulled out from the placement frame 7, and the powdered medicinal materials inside the drawer box 804 can be collected for subsequent use.
