Description

Technical Field

[0001] The present invention relates to the technical field of traditional Chinese medicine decoction pieces production, and in particular to a device for classifying and feeding traditional Chinese medicine decoction pieces. Background Art

[0002] Traditional Chinese medicine decoction pieces are drugs that can be directly used in traditional Chinese medicine clinical practice or preparation production after the Chinese medicinal materials are processed by decocting. Traditional Chinese medicine decoction pieces can be classified in various ways. The following are common classification methods and their specific classifications:

[0003] 1. Classified by medicinal parts, such as rhizome class, stem and wood class, cortex class, leaf class, flower class, etc.;

[0004] 2. Classified by decocting methods, such as processed decoction pieces, water-processed decoction pieces, fire-processed decoction pieces, etc.;

[0005] 3. Classified by efficacy, such as diaphoretics, heat-clearing drugs, purgatives, and drugs for dispelling wind and dampness, etc.

[0006] For flower decoction pieces, due to the usually brittle and tender texture of flower decoction pieces, during the production and transportation process of flower decoction pieces, the flower decoction pieces will drop petals and stamens due to impact or friction. As a result, a large amount of debris will be contained in the finally collected flower decoction pieces. The debris will not only affect the quality of the final packaged flower decoction pieces, but also affect the weighing of flower decoction pieces before packaging. Therefore, it is necessary to screen out the debris before packaging flower decoction pieces. Most traditional screening methods use high-frequency vibrating screens to screen traditional Chinese medicine decoction pieces. Since flower decoction pieces are relatively fragile, the flower decoction pieces will be squeezed against each other or collide with the screen mesh due to high-frequency vibration during screening, resulting in the dropping of some small stamens and petals, thereby affecting the screening efficiency and causing loss of output.

[0007] Therefore, it is necessary to provide a device for classifying and feeding traditional Chinese medicine decoction pieces to solve the above problems. Summary of the Invention

[0008] Based on this, it is necessary to provide a device for classifying and feeding traditional Chinese medicine decoction pieces for the problems of the existing technology.

[0018] The beneficial effects of the present invention compared with the prior art are as follows:

[0019] First, the device screens the flower-like cut pieces through the swing box that swings slowly. During this process, the broken pieces will fall into the guide box, while the whole flower-like cut pieces will be blocked by the long strips, so as to separate the whole flower-like cut pieces. And during the screening process of the flower-like cut pieces, the flower-like cut pieces are not affected by high-intensity vibration. Therefore, through this device, the separation of broken pieces and whole pieces can be promoted on the premise of reducing the damage of the flower-like cut pieces, improving the separation efficiency.

[0020] Second, when screening the flower-like cut pieces, some small flower-like cut pieces will get stuck in the strip-shaped through slots. To prevent a large number of flower-like cut pieces from blocking the strip-shaped through slots, during the reciprocating swing of the swing box, the sliding frame will drive several inserting bars to displace in the corresponding strip-shaped through slots, so as to drive the flower-like cut pieces stuck in the strip-shaped through slots to the supporting flat plate by the inserting bars. And before the sliding frame stops displacing, the top block arranged below the inserting bar will push up the flower-like cut pieces stuck in the strip-shaped through slots, finally effectively preventing a large number of flower-like cut pieces from blocking the strip-shaped through slots.

[0021] Third, when the end of the swing box with the whole-piece outlet is tilted downward, the flower-like cut pieces will slide onto the supporting flat plate. At this time, the lifting frame arranged below the supporting flat plate will rise, so that the lifting frame will drive several top bars to penetrate out of the supporting flat plate. Then, the piled-up flower-like cut pieces on the supporting flat plate are dispersed by the upwardly pushing top bars, finally promoting the falling of the broken pieces among the whole flower-like cut pieces.

[0042] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0043] refer to Figures 1 to 19 The device for classifying and feeding Chinese medicine pieces shown in the figure comprises a long swing box 1, the top of which is an open structure (such as Figure 13 As shown), one end of the swing box 1 is provided with a whole material outlet 2, a rotating baffle 3 is provided on the whole material outlet 2, and the bottom of the swing box 1 is provided with a crushed material outlet 4 (as shown Figure 7 As shown in FIG. 1 , the crushed material outlet 4 and the whole material outlet 2 are spaced apart along the length direction of the swing box 1, and the crushed material outlet 4 divides the bottom of the swing box 1 into a short plate 5 and a long plate 6 (as shown in FIG. 1 ). Figure 13As shown in the figure, a plurality of strip-shaped through grooves 7 are provided at one end of the long plate 6 close to the scrap outlet 4 and are equidistantly distributed along the width direction of the swing box 1. One end of the long plate 6 close to the finished material outlet 2 is a material supporting flat plate 8. A card slot prevention sliding member is provided in the swing box 1. The card slot prevention sliding member includes a sliding frame 9 and a plurality of insertion strips 10. The sliding frame 9 slides along the length direction of the swing box 1. Two groups of symmetric limiting members are provided between the sliding frame 9 and the swing box 1. The plurality of insertion strips 10 are equidistantly distributed along the width direction of the swing box 1. Each insertion strip 10 is connected to the sliding frame 9, and each insertion strip 10 is vertically inserted into the corresponding strip-shaped through groove 7. A top block 11 is slidably provided on each insertion strip 10. A jacking driving member for synchronously driving a plurality of top blocks 11 to rise is provided at the bottom of the material supporting flat plate 8. A fixed baffle 12 is provided beside the scrap outlet 4. A material guiding box 13 is provided at the bottom of the swing box 1. The top of the material guiding box 13 is an open structure. One end of the material guiding box 13 close to the material supporting flat plate 8 is a closed structure. A discharge port 14 is provided at the other end of the material guiding box 13.

[0044] This device is used for classifying and screening flower-based herbal pieces. The specific screening process is as follows: Pour the flower-based herbal pieces into the swing box 1. The flower-based herbal pieces will be supported by the long board 6 at the bottom of the swing box 1. At this time, the broken materials in the flower-based herbal pieces will leak out from the strip-shaped through slots 7, while the whole flower-based herbal pieces cannot fall. After the broken materials fall from the strip-shaped through slots 7, they will fall into the guide box 13 and finally be discharged from the discharge port 14. In order to promote the discharge of the broken materials in the whole flower-based herbal pieces, during screening, the swing box 1 will perform a slow reciprocating swing. When the swing box 1 is in processing, rotating shafts 56 with a horizontal axis are connected to the outer walls on both sides of the swing box 1. In the actual use process, a driving device (not shown in the figure) for driving the rotating shafts 56 to rotate reciprocally is provided beside the swing box 1. Through the reciprocating rotation of the rotating shafts 56, the swing box 1 performs a reciprocating swing similar to a seesaw. During the reciprocating swing of the swing box 1, the flower-based herbal pieces will move back and forth along the length direction of the swing box 1 on the long board 6. When the end of the swing box 1 with the whole material outlet 2 is tilted downward, the flower-based herbal pieces will slide from the end of the long board 6 close to the broken material outlet 4 onto the supporting flat plate 8. During this process, the broken materials in the flower-based herbal pieces will fall into the guide box 13 through the strip-shaped through slots 7. At the same time, the sliding frame 9 will translate towards the whole material outlet 2 by its own gravity. When the sliding frame 9 translates, several inserting strips 10 connected to the sliding frame 9 will bring some small flower-based herbal pieces stuck in the strip-shaped through slots 7 to the supporting flat plate 8. Finally, when the sliding frame 9 is stopped by one group of limiting parts, the jacking driving part will drive the top blocks 11 on each inserting strip 10 to jack up the flower-based herbal pieces stuck in the strip-shaped through slots 7. When the end of the swing box 1 with the broken material outlet 4 is tilted downward, the sliding frame 9 will slide back from the whole material outlet 2 to the broken material outlet 4. When the sliding frame 9 translates in the reverse direction, the top blocks 11 will descend. At the same time, the flower-based herbal pieces that have fallen onto the supporting flat plate 8 will slide towards the broken material outlet 4. During this process, the broken materials in the flower-based herbal pieces will fall into the guide box 13 through the strip-shaped through slots 7. When the sliding frame 9 is stopped by another group of limiting parts, the flower-based herbal pieces will be blocked by several inserting strips 10, and gaps 57 for discharging broken materials are formed between adjacent inserting strips 10. The whole flower-based herbal pieces will not pass through the gaps 57. The broken materials discharged from the gaps 57 will be blocked by the fixed baffle 12 and finally fall into the guide box 13 from the broken material outlet 4. To sum up, with the slow reciprocating swing of the swing box 1, the broken materials in the flower-based herbal pieces will be screened out, and finally all the flower-based herbal pieces obtained are whole materials. Then, when the screening is over, the swing box 1 will swing to make the whole material outlet 2 tilt downward. At this time, the rotating baffle 3 will flip upward, and thus the whole flower-based herbal pieces that have fallen onto the supporting flat plate 8 will be discharged from the whole material outlet 2.

[0045] In order to show the specific installation method of the sliding frame 9, the following features are set:

[0046] Guide sliding rods 15 are fixedly arranged on both sides of the swing box 1. The axis of each guide sliding rod 15 is parallel to the length direction of the swing box 1. A counterweight block 16 is fixedly arranged in the middle of the sliding frame 9 (asFigure 10 As shown in the figure, support rods 17 extending outside the swing box 1 are formed at both ends of the carriage 9. A first guide sliding sleeve 18 is fixedly provided on each support rod 17, and each first guide sliding sleeve 18 slides on a corresponding guide sliding rod 15. Each set of limit members includes two buffer sleeves 19, and the two buffer sleeves 19 are respectively fixedly sleeved on the two guide sliding rods 15. The two buffer sleeves 19 on the same guide sliding rod 15 are respectively close to the fixed baffle 12 and the rotating baffle 3.

[0047] The sliding of the carriage 9 along the length direction of the swing box 1 is realized by the first guide sliding sleeve 18 sleeved on the guide sliding rod 15. When the swing box 1 swings back and forth, the carriage 9 will slide from one end of the swing box 1 to the other end. During this process, the sliding stroke of the carriage 9 is limited by the two buffer sleeves 19 on each guide sliding rod 15, and the inertial impact of the carriage 9 is buffered by the buffer sleeve 19. The counterweight block 16 provided in the middle of the carriage 9 is used to increase the weight of the carriage 9, so as to enable the carriage 9 to slide downward by its own gravity.

[0048] In order to show the specific structure of the top block 11, the following features are set:

[0049] Each top block 11 is strip-shaped, the length direction of each top block 11 is consistent with the length direction of the strip-shaped through groove 7, and a first arc surface 20 is formed on the top of each top block 11 (as Figure 19 shown). A first limit rod 21 and a second limit rod 22 are formed at the bottom of each insert bar 10 (as Figure 12 shown). The first limit rod 21 and the second limit rod 22 are both vertical. Each top block 11 is arranged below the strip-shaped through groove 7, and each top block 11 is located between the insert bar 10 and the material supporting flat plate 8. A second arc surface 23 is formed on one side of each insert bar 10 facing the top block 11. A vertical rod 24 is formed at one end of each top block 11 (as Figure 11 shown). A support block 25 is formed on the vertical rod 24, and a second guide sliding sleeve 26 sleeved on the first limit rod 21 is formed on the support block 25. A limit nut 27 located below the second guide sliding sleeve 26 is screwed at the lower end of each first limit rod 21, and each second limit rod 22 passes downward through the corresponding support block 25.

[0050] In the initial state, the top block 11 is in a descending state due to gravity. At this time, the No. 2 guide sleeve 26 sliding on the No. 1 limit rod 21 will conflict with the limit nut 27 downward, and the limit nut 27 will limit the descending stroke of the No. 2 guide sleeve 26 to prevent the No. 2 guide sleeve 26 from sliding out of the No. 1 limit rod 21. When the top block 11 is in the descending state, the top block 11 is located below the corresponding strip through groove 7, so that a part of the crushed materials falling through the strip through groove 7 will fall from both sides along the No. 1 curved surface 20 at the top of the top block 11 and will not accumulate on the top of the top block 11. When one end of the swing box 1 with the whole material outlet 2 tilts downward, the slide 9 will drive several top blocks 11 to slide toward the supporting plate 8. Before the slide 9 is limited by the corresponding buffer sleeve 19, several top blocks 11 will be synchronously driven up by the jacking drive member, so that each Each of the top blocks 11 will be inserted upward into the corresponding strip grooves 7, and will eventually push out the flower pieces stuck in the strip grooves 7. When the top block 11 slides up and down, the vertical rod 24 passing through the support block 25 prevents the top block 11 from rotating, ensuring that the top block 11 can only slide in the vertical direction. When one end of the swing box 1 provided with the crushed material outlet 4 tilts downward, the slide 9 will slide toward the crushed material outlet 4. At the same time, the flower pieces on the supporting plate 8 will slide toward the slide 9. When the flower pieces slide toward the slide 9, the whole flower pieces are prevented from being discharged from the crushed material outlet 4 by blocking by a number of cuttings 10. At this time, the crushed materials will fall toward the crushed material outlet 4 through the gap 57 between adjacent cuttings 10, and the No. 2 arc surface 23 on the cuttings 10 will cause the crushed materials to slide from both sides of the cuttings 10 to the gap 57, preventing the crushed materials from accumulating on the cuttings 10.

[0051] In order to show the specific structure of the jacking drive, the following features are set:

[0052] The lifting drive member is a contact frame 28 (such as Figure 9 As shown), the abutment frame 28 is located in the material guide box 13, and a first inclined surface 29 is provided at one end of the abutment frame 28 facing the crushed material outlet 4. The lower end of each vertical rod 24 is formed with a first inclined wedge block 30 located in the material guide box 13, and a second inclined surface 31 is provided on the first inclined wedge block 30 to cooperate with the first inclined surface 29.

[0053] In the initial state, each top block 11 is in a descending state due to gravity. Thus, the first inclined wedge block 30 connected to the top block 11 through the vertical rod 24 is also in a descending state. When the first inclined wedge block 30 is in a descending state, its second inclined surface 31 corresponds to the first inclined surface 29. Then, during the process of the carriage 9 sliding from the scrap outlet 4 to the whole material outlet 2, the first inclined wedge block 30 will gradually approach and contact the contact frame 28. Then, before the carriage 9 is stopped by the corresponding buffer sleeve 19, the first inclined wedge block 30 will contact the contact frame 28. At this time, through the cooperation of the first inclined surface 29 and the second inclined surface 31, the first inclined wedge block 30 will drive the top block 11 to rise into the strip-shaped through groove 7. When the carriage 9 slides in the reverse direction, each first inclined wedge block 30 will separate from the contact frame 28. Thus, when the swing box 1 swings from an inclined state to a horizontal state, each top block 11 will drive the first inclined wedge block 30 to slide down again by gravity. Finally, the top block 11 and the first inclined wedge block 30 will be in a descending state again.

[0054] When flower-like cut pieces are stacked on the material supporting flat plate 8, in order to promote the falling of the scraps in the flower-like cut pieces, the following features are provided:

[0055] A lifting frame 32 is provided below the material supporting flat plate 8 (as Figure 18 shown). A plurality of uniformly distributed top bars 33 are fixedly provided at the top of the lifting frame 32. The upper end of each top bar 33 vertically passes through the material supporting flat plate 8, and the top of each top bar 33 is flush with the top of the material supporting flat plate 8 (as Figure 9 shown). Four fixing rods 34 distributed in a matrix are formed at the bottom of the material supporting flat plate 8. Each fixing rod 34 is perpendicular to the material supporting flat plate 8, and the upper end of each fixing rod 34 is fixedly connected to the material supporting flat plate 8. Three guide sleeves 35 are formed on the lifting frame 32 and sleeved on the four fixing rods 34 respectively. A screw cap 36 is screwed at the lower end of each fixing rod 34 and located below the corresponding third guide sleeve 35. A lifting driving member for driving the lifting of the lifting frame 32 is provided on the swing box 1.

[0056] When the end of the rocking box 1 with the broken material outlet 4 is inclined downward, the lifting frame 32 is in a descending state due to gravity. At this time, the descending stroke of the lifting frame 32 is restricted by four nuts 36 to prevent the third guide sleeve 35 from sliding out of the corresponding fixed rod 34. When the lifting frame 32 is in the descending state, the top of each top bar 33 is flush with the top of the material supporting flat plate 8. When the end of the rocking box 1 with the whole material outlet 2 is inclined downward, the sliding frame 9 will slide towards the whole material outlet 2. Before the sliding frame 9 is stopped by the corresponding buffer sleeve 19, the lifting driving member will drive the lifting frame 32 to rise. In this way, several top bars 33 on the lifting frame 32 will protrude out of the material supporting flat plate 8, and the flower-like decoction pieces that have fallen on the material supporting flat plate 8 are dispersed by the rising top bars 33, so as to promote the falling of the broken materials between the whole flower-like decoction pieces, and further improve the efficiency of broken material screening. When the rocking box 1 swings in the reverse direction, the lifting frame 32 will fall again due to gravity, and finally the top of each top bar 33 will be flush with the top of the material supporting flat plate 8 again.

[0057] In order to show the specific structure of the lifting driving member, the following features are set:

[0058] The lifting driving member includes two groups of sliding contact members respectively arranged on both sides of the rocking box 1. Each group of sliding contact members includes a fourth guide sleeve 37, a fifth guide sleeve 38 and a strip-shaped rod 39. Below each guide rod 15, there is a third limiting rod 40 parallel to it (as Figure 4 shown). One end of the third limiting rod 40 is fixedly connected to the rocking box 1 through a vertical connection frame 41, and a limiting block 42 is formed at the other end of the third limiting rod 40. The fourth guide sleeve 37 is sleeved on the corresponding guide rod 15, the fifth guide sleeve 38 is sleeved on the corresponding third limiting rod 40, a spring 43 is sleeved on the third limiting rod 40, and the two ends of the spring 43 are respectively in contact with the fifth guide sleeve 38 and the vertical connection frame 41. A first connecting plate 44 connecting the two is arranged between the fourth guide sleeve 37 and the fifth guide sleeve 38. A second connecting plate 45 is formed on the fifth guide sleeve 38, and the strip-shaped rod 39 is fixedly connected to the second connecting plate 45 and is parallel to the guide rod 15. Second inclined wedge blocks 46 are fixedly arranged on both sides of the lifting frame 32, and a third inclined surface 47 is arranged on each second inclined wedge block 46. A fourth inclined surface 48 that is inclined and matched with the third inclined surface 47 is arranged at one end of each strip-shaped rod 39.

[0059] After the fourth guide sleeve 37 is sleeved on the corresponding guide rod 15, the fourth guide sleeve 37 is located between two corresponding buffer sleeves 19. When the end of the swing box 1 with the shredding outlet 4 tilts downward, the carriage 9 slides towards the shredding outlet 4. At this time, each spring 43 releases elastic force to drive the corresponding fifth guide sleeve 38 to slide towards the corresponding limit block 42, and the limit block 42 is used to prevent the fifth guide sleeve 38 from sliding out of the corresponding third limit rod 40. At the same time, the strip-shaped rod 39 connected to the fifth guide sleeve 38 through the second connecting plate 45 is separated from the second wedge block 46. When the end of the swing box 1 with the finished material outlet 2 tilts downward, the carriage 9 slides towards the finished material outlet 2. During this process, the first guide sleeve 18 sliding on the guide rod 15 will translate towards the fourth guide sleeve 37. When the first guide sleeve 18 abuts against the fourth guide sleeve 37, driven by the gravity of the counterweight block 16 on the carriage 9, the fifth guide sleeve 38 will overcome the elastic force of the spring 43 to drive the strip-shaped rod 39 to slide towards the second wedge block 46. When one end of the strip-shaped rod 39 abuts against the second wedge block 46, through the cooperation of the third inclined surface 47 and the fourth inclined surface 48, the two second wedge blocks 46 will synchronously drive the lifting frame 32 to rise, so that several top bars 33 on the lifting frame 32 protrude upward from the material supporting flat plate 8, and the top bars 33 protruding from the material supporting flat plate 8 are used to disperse the flower-like decoction pieces piled up on the material supporting flat plate 8.

[0060] In order to enable the flower-like decoction pieces to slide smoothly onto the material supporting flat plate 8, the following features are provided:

[0061] A plurality of strip-shaped through grooves 7 divide one end of the long plate 6 into a plurality of long strip blocks 49, and a third arc surface 50 is formed on the top of each long strip block 49 (as Figure 14 shown), and a guide sliding inclined platform 51 is formed on one end of the material supporting flat plate 8 facing the shredding outlet 4 (as Figure 9 shown).

[0062] The flower-like decoction pieces falling into the swing box 1 will be supported by a plurality of long strip blocks 49, and the third arc surface 50 provided on the top of the long strip blocks 49 is used to promote the shredded materials to slide into the strip-shaped through grooves 7 on both sides of the long strip blocks 49. During the process of the flower-like decoction pieces sliding from a plurality of long strip blocks 49 to the material supporting flat plate 8, the guide sliding inclined platform 51 provided on one end of the material supporting flat plate 8 enables the flower-like decoction pieces to slide smoothly onto the material supporting flat plate 8.

[0063] In order to show how the rotating baffle 3 flips, the following features are provided:

[0064] The upper end of the rotating baffle 3 is hinged to the swing box 1. Push-pull shafts 52 are formed on both sides of the rotating baffle 3. Hydraulic cylinders 53 are provided on both sides of the swing box 1. The output end of the hydraulic cylinder 53 is rotationally connected to the push-pull shaft 52, and the other end of the hydraulic cylinder 53 is hinged to the outer wall of the swing box 1.

[0065] The hydraulic cylinders 53 provided on both sides of the swing box 1 are used to synchronously drive the rotary baffle 3 to turn over. When screening flower-like cut pieces, the output ends of the two hydraulic cylinders 53 retract synchronously to drive the rotary baffle 3 to block the whole material outlet 2. When the flower-like cut pieces have been screened, the output ends of the two hydraulic cylinders 53 extend synchronously to drive the rotary baffle 3 to turn up, finally opening the whole material outlet 2.

[0066] In order to facilitate the discharge of the whole flower-like cut pieces from the whole material outlet 2, the following features are provided:

[0067] A number of spray heads 54 are fixedly provided on the fixed baffle 12 and are equally spaced along the width direction of the swing box 1 (as Figure 17 shown), each spray head 54 faces the whole material outlet 2, and a dust cover 55 covering the top opening of the swing box 1 is fixedly provided at the top of the swing box 1.

[0068] When the flower-like cut pieces have been screened, the end of the swing box 1 provided with the whole material outlet 2 will tilt downward. At the same time, the rotary baffle 3 will turn up to open the whole material outlet 2, so that the flower-like cut pieces stacked on the material supporting flat plate 8 will be discharged from the whole material outlet 2. At this time, a number of spray heads 54 connected to the fixed baffle 12 will blow air toward the whole material outlet 2 to facilitate the discharge of the flower-like cut pieces from the whole material outlet 2.

[0069] Working principle:

[0070] This device is used for classifying and screening flower-based decoction pieces. The specific screening process is as follows: Pour the flower-based decoction pieces into the swing box 1. The flower-based decoction pieces will be supported by the long board 6 at the bottom of the swing box 1. At this time, the broken materials in the flower-based decoction pieces will leak out from the strip-shaped through groove 7, while the whole flower-based decoction pieces cannot fall. After the broken materials fall from the strip-shaped through groove 7, they will fall into the material guiding box 13 and finally be discharged from the discharge port 14. In order to promote the discharge of broken materials in the whole flower-based decoction pieces, during screening, the swing box 1 will perform a slow reciprocating swing. When the swing box 1 is being processed, rotating shafts 56 with a horizontal axis are connected to the outer walls on both sides of the swing box 1. In the actual use process, a driving device (not shown in the figure) for driving the rotating shafts 56 to rotate reciprocally is provided beside the swing box 1. Through the reciprocating rotation of the rotating shafts 56, the swing box 1 performs a reciprocating swing similar to a seesaw. During the reciprocating swing of the swing box 1, the flower-based decoction pieces will move back and forth along the length direction of the swing box 1 on the long board 6. When the end of the swing box 1 with the whole material outlet 2 is tilted downward, the flower-based decoction pieces will slide from the end of the long board 6 close to the broken material outlet 4 onto the material supporting flat plate 8. During this process, the broken materials in the flower-based decoction pieces will fall into the material guiding box 13 through the strip-shaped through groove 7. At the same time, the sliding frame 9 will translate towards the whole material outlet 2 by its own gravity. When the sliding frame 9 translates, several inserting strips 10 connected to the sliding frame 9 will bring some small flower-based decoction pieces stuck in the strip-shaped through groove 7 towards the material supporting flat plate 8. Finally, when the sliding frame 9 is stopped by one group of limiting parts, the jacking driving part will drive the top blocks 11 on each inserting strip 10 to jack up the flower-based decoction pieces stuck in the strip-shaped through groove 7. When the end of the swing box 1 with the broken material outlet 4 is tilted downward, the sliding frame 9 will slide back from the whole material outlet 2 towards the broken material outlet 4. When the sliding frame 9 translates in the reverse direction, the top blocks 11 will descend. At the same time, the flower-based decoction pieces that have fallen onto the material supporting flat plate 8 will slide towards the broken material outlet 4. During this process, the broken materials in the flower-based decoction pieces will fall into the material guiding box 13 through the strip-shaped through groove 7. When the sliding frame 9 is stopped by another group of limiting parts, the flower-based decoction pieces will be blocked by several inserting strips 10, and a gap 57 for discharging broken materials is formed between adjacent inserting strips 10. The whole flower-based decoction pieces will not pass through the gap 57. The broken materials discharged from the gap 57 will be blocked by the fixed baffle 12 and finally fall into the material guiding box 13 from the broken material outlet 4. To sum up, with the slow reciprocating swing of the swing box 1, the broken materials in the flower-based decoction pieces will be screened out, and finally all the flower-based decoction pieces obtained are whole materials. Then when the screening is over, the swing box 1 will swing until the whole material outlet 2 is tilted downward. At this time, the rotating baffle 3 will flip upward, and thus the whole flower-based decoction pieces that have fallen onto the material supporting flat plate 8 will be discharged from the whole material outlet 2.
