[0033] In this embodiment, when in use, the Chinese medicine decoction pieces to be conveyed are put into the fixed feeding hard pipe 7, and the materials are conveyed into the protective conveying cylinder 1 through the feeding soft pipe 9; the feeding motor 6 is started, the feeding motor 6 drives the conveying auger 5 to rotate, and the decoction pieces are sent to the end of the hinged seat 4 for conveying, and then are discharged through the discharging soft pipe 10 and the discharging hard pipe 8. The end lifting driving mechanism simultaneously lifts / drops the tail end of the protective conveying cylinder 1 according to the set frequency, so that the protective conveying cylinder 1 reciprocatingly lifts and swings around the hinged seat 4; during the swinging process, the conveying auger 5 always keeps feeding, so as to form the action of “conveying and shaking at the same time”, and prevent the decoction pieces from being accumulated and blocked in the cylinder.

[0034] During the conveying process, the dust removal mechanism continuously operates, and the air in the protective conveying cylinder 1 with dust is extracted, filtered and discharged as clean air; because the swinging range of the protective conveying cylinder 1 is limited by the flexibility of the feeding soft pipe 9 and the discharging soft pipe 10, the feeding hard pipe 7 and the discharging hard pipe 8 keep the positions unchanged through the stabilizing frame 11 and the stabilizing plate 12 respectively, so as to ensure the reliable connection of the upstream and downstream equipment.

[0035] In the scheme, the protective conveying cylinder 1 is fully enclosed, combined with the dust removal mechanism, the dust is limited and concentrated for treatment, and the cleanliness of the workshop is significantly improved; reciprocating lifting and swinging makes the decoction pieces continuously turn, which not only eliminates the bridging and blocking, but also fully exposes the fine powder mixed to be sucked and removed, so that the blocking and dust removal are completed at one time; the soft tube is connected between the feeding hard tube 7, the discharging hard tube 8 and the protective conveying cylinder 1, which not only isolates the vibration but also avoids leakage, the whole machine structure is compact and the maintenance cycle is long, and it is suitable for automatic and dust-free continuous production of traditional Chinese medicine decoction pieces.
