The circumferential surface of the barrel is provided with a plurality of rows of sieve mesh rows distributed along the axial direction of the barrel, and each row of sieve mesh rows is provided with a plurality of sieve meshes 5 distributed along the circumferential direction of the barrel. The outer peripheral surface of the cylinder body is a smooth surface and is provided with a chromium coating. The sieve pores are round holes. Radial extension of the mesh bowl. The high end of the cylinder body is provided with an inner retainer ring 6 which extends along the axial direction of the cylinder body. The frame is provided with a feeding hopper 7 with an outlet end extending into the high end of the cylinder. The frame is provided with a coarse medicine feeding hopper 8 for receiving the coarse traditional Chinese medicine at the lower end of the barrel body and a fine medicine feeding hopper 9 for receiving the coarse traditional Chinese medicine through the sieve pores of the barrel body. The present invention further includes a drum rotating motor 10 for driving the rotation of the driving shaft. One end of the rotating shaft of the cylinder rotating motor is coaxially connected with the high end of the driving rotating shaft. The push rod 11 extends from one end of the cylinder to the other. The two ends of the push rod are fixed with the frame through a connecting rod 12 respectively. The push rod is used for pushing the part of the Chinese herbal pieces, which extends out of the sieve pores and is toppled towards the front of the rotation direction of the cylinder body (the rotation direction of the cylinder body is the clockwise direction in figure 2), towards the back of the rotation direction of the cylinder body. The end of the push rod remote from the barrel is provided with an end plate 13 located on the rear end of the push rod in the direction of rotation of the barrel. An air distribution cavity 14 is arranged in the end plate. The side 15 of the push rod located at the rear end in the rotational direction of the cylinder is a flat surface. The air distribution chamber is provided with an air inlet 29. The air distribution chamber is provided with a plurality of air blowing holes 16 distributed along the extension direction of the push rod. The blow holes are located on the surface of the end plate facing the cylinder side. The opening direction of the air blowing hole is parallel to the side surface of the push rod at the rear end of the cylinder in the rotating direction. When the barrel rotates to the position that the edge 17 of the front end of the sieve hole along the rotating direction of the barrel is positioned on the plane of the side surface of the rear end of the push rod in the rotating direction of the barrel, the sieve holes with the edges positioned on the plane of the side surface of the rear end of the push rod in the rotating direction of the barrel are aligned with the air blowing holes in a one-to-one correspondence mode.

The connecting strip is provided with a blowing hole 19 communicated with the air distribution cavity. The air blowing hole is arranged on the surface of one side of the connecting strip facing the push rod. When the barrel rotates to the position that the edge of the front end of the sieve pore along the rotation direction of the barrel is positioned on the plane of the side surface of the push rod positioned at the rear end of the rotation direction of the barrel, the part of the Chinese herbal pieces, which is exposed outside the barrel, in the sieve pore of which the edge is positioned on the plane of the side surface of the push rod positioned at the rear end of the rotation direction of the barrel can be blown by the wind blowing hole. The opening direction line of the blowing hole and the opening direction line of the blowing hole are correspondingly positioned on the same plane one by one. When the barrel rotates to the position that the edge of the front end of the sieve pore along the rotation direction of the barrel is positioned on the plane of the side surface of the push rod positioned at the rear end of the rotation direction of the barrel, the distance between the outer end of the sieve pore blocked on the plane of the side surface of the push rod positioned at the rear end of the rotation direction of the barrel and the neutral line of the barrel is the farthest distance from the outer end of the sieve pore and the opening direction line of the air blowing hole positioned on the same plane as the aligned air outlet hole of the sieve pore blocked on the plane of the side surface of the push rod positioned at the rear end of the rotation direction of the barrel, wherein the distance L is larger than zero and smaller than 3 mm. The end of the connecting strip far away from the air distribution cavity is provided with brush bristles 20 for brushing the surface of the cylinder body. The push rod, the air distribution cavity and the connecting strip are enclosed into a U-shaped pressurizing groove 21. The air blowing hole is positioned in the pressurizing groove. A cutting edge 22 extending in the extension direction of the push rod is formed between the end surface of the push rod facing one end of the cylinder and the side surface of the push rod located at the rear end in the rotation direction of the cylinder. One side surface of the cutting edge is contacted and abutted with the cylinder surface. The end face of the push rod facing one end of the barrel is provided with a plurality of mounting holes 23 which are aligned with the sieve mesh rows in a one-to-one correspondence mode, and a pressing ball 24 and a pressing ball ejection spring 25 for driving the pressing ball to extend out of the mounting holes are arranged in the mounting holes. The diameter of the pressing ball is larger than that of the sieve pore.
When the feeding device is used, the traditional Chinese medicine decoction pieces are poured into the barrel from the high end of the barrel through the feeding hopper, the barrel continuously rotates under the driving of the barrel driving motor, the traditional Chinese medicine decoction pieces move towards the low end of the barrel while rotating along with the barrel in the barrel, the traditional Chinese medicine decoction pieces are screened in the process, the thick traditional Chinese medicine decoction pieces fall out from the low end of the barrel to the thick medicine feeding hopper to flow out, and the thin traditional Chinese medicine decoction pieces fall out from the screen holes to the thin medicine feeding hopper to flow out. The continuous pivoted process sieve mesh of barrel is dredged, and the process that the sieve mesh specifically was dredged is: the traditional Chinese medicine decoction pieces which extend out of the sieve pores and are blocked in the sieve pores (hereinafter referred to as protruding traditional Chinese medicine decoction pieces which extend out of the sieve pores and are blocked in the sieve pores) firstly pass through the bristles and are flexibly pushed by the bristles, then the protruding traditional Chinese medicine decoction pieces reach the pressurizing groove, the part, extending out of the sieve pores, of the protruding traditional Chinese medicine decoction pieces, which are inclined towards the rear of the rotation direction of the cylinder body, move towards the front of the rotation direction of the cylinder body under the action of air blown by the air blowing holes, then the protruding traditional Chinese medicine decoction pieces are contacted with the push rod, the part, extending out of the sieve pores, of the protruding traditional Chinese medicine decoction pieces, which are inclined towards the front of the rotation direction of the cylinder body, move towards the rear of the rotation direction of the cylinder body, the part, extending out of the sieve pores, and the traditional Chinese medicine decoction pieces blocked in the sieve pores fall into the cylinder body under the action of air flow blown by the air blowing holes; if the Chinese herbal pieces blocked in the sieve holes are not pushed out of the barrel body, the part of the Chinese herbal pieces blocked in the sieve holes, which protrudes out of the barrel body, is cut off under the action of the cutting edge, and then the Chinese herbal pieces blocked in the sieve holes are driven towards the inside of the barrel body for the second time to fall into the barrel body under the action of the pressing ball ejecting spring matched with the pressing ball.
