As the rotating cylinder 2 rotates, when the hung medicine residue reaches the upper part of the rotating cylinder 2, due to gravity, the depth of the conveying groove 3 on both sides is different. At the same time, the medicine residue will fall down. A conveying plate 4 with a semicircular cross-section is arranged inside the rotating drum 2. The front end of the conveying plate 4 is fixed together with the front end of the inner part of the outer drum 1. A number of evenly distributed stirring fins 5 are installed at the lower end of the outer part of the conveying plate 4.

The front ends of the two sieve plates are also fixed on the front side wall inside the outer drum 1. Inclined collecting plates 9 are installed on both sides of the upper end of the first sieve plate 7, and the upper end of the collecting plate 9 expands to both sides.

[0027] First, in order to facilitate the collection of the medicine residues that fall out of the conveying trough 3 from the upper side of the inside of the rotating drum 2, and second, in order to prevent the medicine residues from falling from both sides of the sieve plate when the first sieve plate 7 is sieving, a spiral fin 11 is arranged between the collecting plates 9 inside the outer cylinder 1, and the front end of the spiral fin 11 is rotatably connected to the front side of the inside of the outer cylinder 1, and the rear end of the spiral fin 11 is rotatably connected to the rear side of the inside of the mounting box 10. A servo motor 12 for controlling the rotation of the spiral fin 11 is installed on the front side of the outside of the outer cylinder 1, and an I-shaped bracket 14 is arranged at the lower part of the outside of the outer cylinder 1, and a main hinge support 15 and a main hinge support 16 are respectively installed on the front and rear sides of the upper side of the bracket 14. A secondary hinge support 16, the secondary hinge support 16 and the installation box 10 are connected together through a lifting cylinder 17, the front end of the lower side of the outer tube 1 is hinged to the upper end of the main hinge support 15, the lower end of the lifting cylinder 17 is hinged to the upper end of the secondary hinge support 16, the upper end of the lifting cylinder 17 is hinged to the lower side of the outer side of the installation box 10, the rise and fall of the installation box 10 is controlled by the extension and retraction of the lifting cylinder 17, and the inclination degree of the outer tube 1 is controlled, an L-shaped feeding pipe 18 is installed at the lower end of the outer rear side of the installation box 10, and the front end of the feeding pipe 18 extends to the interior of the rotating drum 2, so as to facilitate the addition of the slag to be screened into the interior of the rotating drum 2.

[0028] The utility model connects the two sides of the outside of the second sieve plate 6 to the two upper ends of the inside of the conveying plate 4, respectively, and connects the two sides of the lower end of the first sieve plate 7 to the two sides of the outer upper end of the conveying plate 4, and the front side of the outside of the outer cylinder 1 is installed at the lower side of the servo motor 12 with an L-shaped first discharge pipe 19 used in conjunction with the first sieve plate 7, and the front side of the outside of the outer cylinder 1 is installed at the lower side of the first discharge pipe 19 with an L-shaped second discharge pipe 20 used in conjunction with the second sieve plate 6, and the front side of the outside of the outer cylinder 1 is installed at the lower side of the second discharge pipe 20 with an L-shaped third discharge pipe 21 used in conjunction with the conveying plate 4, and the front side of the outside of the outer cylinder 1 is installed at the lower side of the third discharge pipe 21 A fourth discharge pipe 22 used in conjunction with the rotating drum 2 facilitates the classification and collection of medicinal residues of different diameters through the four discharge pipes. A connecting ring 23 is arranged on the rear side of the outside of the rotating drum 2. The connecting ring 23 is located on the front side of the inside of the mounting box 10. A gear 24 is arranged inside the mounting box 10. The gear 24 is sleeved on the rotating shaft on the front side of the spiral fin 11. The rotation of the spiral fin 11 can drive the gear 24 to rotate. A plurality of evenly distributed tooth grooves 25 meshing with the gear 24 are provided inside the connecting ring 23, so that the spiral fin 11 and the rotating drum 2 can rotate at the same time, and the medicinal residue is transported forward by the rotation of the spiral fin 11, forming a coupled driving structure 13.

[0029] When the utility model is implemented in a specific manner, the medicinal residue to be screened is first put into the interior of the drum 2 from the feed pipe 18. After the medicinal residue enters the interior of the drum 2, the servo motor 12 is started to stir the medicinal residue first. At this time, the length of the lifting cylinder 17 is first controlled to prevent the two ends of the outer cylinder 1 from having too large a height difference, so as to control the speed at which the medicinal residue slides on the sieve plate. The drum 2 rotates, driving the medicinal residue to rotate inside the drum, and the medicinal residue is scattered by the stirring fins 5. The medicinal residue rotates inside along with the conveying trough 3 on the inner wall of the drum 2. As the medicinal residue gradually rotates upward inside the drum 2, the medicinal residue inside the conveying trough 3 falls between the collecting plates 9, and the lifting cylinder 17 is extended. The lifting cylinder 17 lifts the mounting box 10, and the medicinal residue on the first sieve plate 7 slides forward and is transported by the spiral fins 11 on the upper side of the first sieve plate 7. After two screenings, the medicinal residue enters the second sieve plate 6 and the conveying plate 4 respectively, and some residues that are too small remain inside the drum 2 and are discharged through four discharge pipes respectively.

The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
