It is well known to technical personnel in this field. Therefore, technical personnel in this field can clearly obtain the corresponding use effect through the technical solution provided by the utility model.

[0042] A Chinese medicine powder screening device, the working principle is as follows:

[0043] 1) When in use, the Chinese medicine powder to be screened is placed inside the screen barrel 4 through the feed channel 6, and the motor 7 is started, thereby driving the screen barrel 4 to rotate repeatedly for screening. Qualified Chinese medicine powder can pass through the sieve holes on the screen barrel 4 and fall into the inner bottom of the screening box 1 under the action of gravity, and then slide out of the device through the discharge port 12, and then a collection box is placed on one side of the discharge port 12 for collection;

[0044] 2) Unqualified Chinese medicine powder will remain inside the screening barrel 4. When there is a lot of unqualified Chinese medicine powder inside or the screening is completed, the motor 7 is turned off, the electric push rod 8 is retracted, and the blocking block 10 is driven to leave the through slot 41, and then the unqualified Chinese medicine powder enters the feeding pipe 2 through the through slot 41, and finally is discharged from the device through the discharge through slot 3. A collection box is placed on one side of the discharge through slot 3 for collection;

[0045] 3) After the unqualified Chinese medicine powder is discharged, the electric push rod 8 extends and pushes the blocking block 10 upward, so that it can re-block the through groove 41 to facilitate continued work, and the feeding channel 6 can continue to add materials during the screening process. The setting of the baffle 61 can also prevent dust from overflowing.

[0046] Compared with the prior art, the present invention has the following beneficial effects:

[0047] The novel method uses a motor 7 to drive the sieve barrel 4 to rotate repeatedly for screening. The buffer rod 9 and the blocking block 10 can open the through slot 41 of the sieve barrel 4 under the drive of the electric push rod 8, so that the insufficiently broken traditional Chinese medicine can be discharged from the sieve barrel 4. It is very convenient to use. The setting of the baffle 61 can also prevent dust from overflowing during the screening process. Therefore, it is very convenient to use to continuously add materials through the feed channel 6 during the screening process, thereby ensuring the practicability of the device.
