Specific embodiment 1

[0032] See also Figure 1-4 The utility model is a Chinese herbal medicine powder screening device, comprising a screening box 1 and a universal wheel 3 arranged at the bottom thereof, through which the screening box 1 can be pushed and shifted.

[0033] Specifically, a top groove 102 for installing a box cover 4 is provided on the top of the screening box 1, and a controller 3 for controlling the entire electronic control components in the device is installed on the side wall of the screening box 1.

[0034] Furthermore, a circular feed opening 102a is provided at the center of the top groove 102, and a circular feed opening 401 is also provided at the center of the box cover 4, and the feed opening 401 and the feed opening 102a are coaxially arranged.

[0035] The operation process of this embodiment is: the universal wheels 2 at the bottom of the screening box 1 can be moved by holding the screening box 1 and exerting force on it, and when the universal wheels 2 move, the screening box 1 can be moved to a designated position. Specific embodiment 2

[0037] See also Figure 5 On the basis of the specific embodiment 1, a feeding component 5 is further provided. The feeding component 5 includes a feeding hopper 501, a connecting pipe 502 and a dust cover 503. The dust cover 503 can be used to block the position of the feeding port 102a to a certain extent, thereby reducing the reverse overflow of Chinese medicinal material dust. At the same time, the disc 502a and the rotating rod 502b in the connecting pipe 502 can be used to flip the material during feeding, so that the Chinese medicinal material powder passes through the disc 502a and enters the screening box 1. After the material is unloaded, the metal plate 502c and the adsorption plate 501b-1 ensure that the metal plate 502c lies across the connecting pipe 502, thereby preventing the reverse escape of Chinese medicinal material dust.

[0038] Specifically, the feed hopper 501 in the feed assembly 5 is connected to the dust cover 503 through the connecting pipe 502 at the bottom thereof, wherein the dust cover 502 is covered on the feed port 102a, and a rotating rod 502b is inserted through the connecting pipe 502, and the connecting pipe 502 is connected to the disc 502a through the rotating rod 502b inserted therein.

[0040] The operation process of this embodiment is as follows: when in use, the Chinese medicinal material powder is fed into the feed hopper 501, and then the Chinese medicinal material powder passes through the feed hopper 501 and enters the connecting pipe 502 below. The falling of the Chinese medicinal material during feeding generates an impact force on the disc 502a, and this impact force causes the metal plate 502c to break away from the adsorption force of the adsorption plate 501b-1. At this time, the notch of the connecting pipe 502 is exposed, and the Chinese medicinal material powder passes through the connecting pipe 502 and enters the screening machine. The inside of the screening box 1, and when the Chinese medicinal material powder enters the inside of the screening box 1, it will generate an impact force on the screening component 8, and then the dust will escape to one side of the connecting pipe 502, at which time it will be blocked by the dust bag 503a in the dust cover 503, and the disc 502a will resume its horizontal state again because it is not affected by the impact force of the Chinese medicinal material powder and under the combined action of the adsorption force of the adsorption plate 501b-1 on the metal plate 502c, thereby further blocking the reverse escape of the Chinese medicinal material powder.
