At the same time, a stabilizing rod 4 is installed between the two groups of supporting feet 1 to enhance the stability of the two groups of supporting feet 1. Then the collecting box 5 is inserted into the interior of the frame 2 to fix the collecting box 5 and the fixing box 6 on the frame 2.

[0033] In this embodiment, a material discharge pipe 19 is fixed to the outside of the collecting box 5, and a material discharge port is opened at the bottom of the material discharge pipe 19 away from the collecting box 5. An extension sleeve 20 is fixedly connected to the left end of the receiving frame 10, and the extension sleeve 20 extends to the inside of the material discharge pipe 19. A second baffle plate 21 is fixedly connected to the end of the receiving frame 10 away from the extension sleeve 20. When the weighing module inside the receiving frame 10 finishes working, the guide plate 11 is tilted to achieve the accumulation of weighed medicinal materials on one side of the receiving frame 10, and the receiving frame 10 is shaken at the same time. After the movement, it will generate thrust on the Chinese medicinal materials, and then the Chinese medicinal herbs will pass from the inside of the extension sleeve 20 to the inside of the feeding pipe 19, so that the weighed Chinese medicinal materials can be fed. Then, the large impurities inside the screening frame 12 are guided by the inclined surface of the first screening net 13, and finally slide from the inside of the through groove 16 to the inside of the fixed box 6 for unified collection. When passing through the inside of the through groove 16, the design of the second baffle 21 can prevent large impurities from falling into the inside of the receiving frame 10, so as to quickly complete the separation of standard and non-standard medicinal materials.

When it is necessary to discharge Chinese medicinal materials, the roller 34 is slidably connected, and the track 33 will directly limit the roller 34 to realize its movement along a predetermined route, thereby driving the bracket 35 to move, and then driving the blocking plate 37 to follow the movement, thereby removing the blockage between the collecting box 5 and the lower hopper 8.

[0036] In this embodiment, support columns 38 are fixedly connected between the brackets 35, and a protruding plate 39 is fixedly connected to the bottom end of the fixed plate 32. A straight groove 40 is provided inside the protruding plate 39, and a slide groove 41 is provided inside the straight groove 40. The interiors of the straight groove 40 and the slide groove 41 are interconnected. Four groups of connecting rods 36 are provided, and a positioning column 42 is fixedly connected to the bottom of one group of connecting rods 36. The positioning column 42 extends to the interior of the straight groove 40. An extension seat 43 is symmetrically fixedly connected to the middle of the fixed plate 32. A vertical shaft 44 is rotatably connected to the interior of the extension seat 43. A gear 45 is fixedly connected to the exterior of the vertical shaft 44. A rack 46 is fixedly connected to the interior of the support column 38. The gear 45 and the rack 46 are adapted for use. The inner wall of the collection box 5 and the lower part of the track 33 are fixedly connected. A drainage plate is connected, and a group of motors are installed on the protruding plate 39 at the top. At the same time, the output end of the motor is connected to the vertical shaft 44 to realize the rotation of the vertical shaft 44 and drive the gear 45.

At the same time, as the roller 34 moves, the positioning column 42 slides inside the straight groove 40, so that the blocking plate 37 completely releases the blockage of the lower hopper 8, and the Chinese medicine in the lower hopper 8 falls directly into the inside of the drainage plate due to inertia, and finally falls into the inside of the screening frame 12.

[0037] In this embodiment, a rectangular frame 47 is fixedly connected to the lower part of the discharge pipe 19, a fixed cylinder 48 is fixedly connected to the middle of the top of the rectangular frame 47, an extension cylinder 49 is fixedly connected to the top of the fixed cylinder 48, an impact rod 50 is slidably connected to the extension cylinder 49, a second spring 51 is sleeved on the outside of the impact rod 50, a contact head 52 is fixedly connected to the top of the impact rod 50, an insert cylinder 53 is fixedly connected to the top of the rectangular frame 47 and located on the outside of the fixed cylinder 48, a third spring 54 is fixedly connected to the inside of the insert cylinder 53, a flat plate 55 is fixedly connected to the top of the third spring 54, an extrusion sleeve 56 is fixedly connected to the top of the flat plate 55, a rotating wheel 57 is rotatably connected to the outside of the rectangular frame 47, two sets of horizontal shafts 58 are fixedly connected to the inside of the rotating wheel 57, a crank 59 is fixedly connected to the side close to the two sets of horizontal shafts 58, a swing rod 60 is rotatably connected to the inside of the crank 59, and a connecting sleeve 61 is rotatably connected to the outside of the swing rod 60 and located on the inside of the fixed cylinder 48 The top of the connecting sleeve 61 is fixedly connected with an auxiliary cylinder 62, and the impact rod 50 extends to the inside of the auxiliary cylinder 62. Since part of the discharge pipe 19 is designed to be bent, it will cause congestion when some Chinese medicinal materials are discharged. By arranging belts on the outside of the two sets of rotating wheels 57, the horizontal axis 58 is rotated, and then the crank 59 drives the swing rod 60 to rotate. At the same time, the design of the connecting sleeve 61 will limit the top of the swing rod 60, so that the rotational motion of the swing rod 60 is converted into a lifting motion, and then the impact rod 50 is pulled, and the second spring 51 is compressed at the same time. As the impact rod 50 moves up and down, it hits the flat plate 55, and then the flat plate 55 is lifted upward at the same time, stretching the third spring 54. When the impact rod 50 falls, the third spring 54 is reset, so that the flat plate 55 is shaken, and then the extrusion sleeve 56 knocks on the discharge pipe 19, thereby generating a vibration force to break up the jammed Chinese medicinal materials and facilitate discharge.

[0038] Implementation plan: by placing the support foot 1 at the designated position, the frame 2 is then driven to be in a vertical position. At the same time, a stabilizing rod 4 is installed between the two sets of support feet 1 to enhance the stability of the two sets of support feet 1. Then, the collecting box 5 is inserted into the interior of the frame 2 to fix the collecting box 5 and the fixing box 6 on the frame 2. At the same time, a cover 7 is provided to make the collecting box 5 in a closed state to prevent the leakage of medicinal materials. Then, the medicinal materials are placed in the lower hopper 8. A set of motors is installed on the protruding plate 39 at the top. At the same time, the output end of the motor is connected to the vertical shaft 44 to realize the rotation of the vertical shaft 44 and drive the gear 45. The gear 45 will directly mesh with the rack 46 to generate thrust on the rack 46, thereby realizing the translation of the support column 38 and positioning at the same time. The column 42 will slide from the slide groove 41 to the inside of the straight groove 40, and drive the connecting rod 36 to change from inclined to vertical, so that the blocking plate 37 is separated from the inner wall of the collecting box 5. At the same time, as the roller 34 moves, the positioning column 42 slides inside the straight groove 40, so that the blocking plate 37 completely releases the blockage of the lower hopper 8, and the Chinese medicine in the lower hopper 8 falls directly into the inside of the drainage plate due to inertia, and finally falls into the inside of the screening frame 12. By inserting the output end of the motor into the inside of the rotating block 29 and away from the inside of the linkage rod 30, the rotating block 29 is rotated, and then the rotating block 29 drives the linkage rod 30 to rotate, so that the first slider 26 and the second slider 27 move closer to and away from each other, and at the same time, the first accommodating groove 24 and The second accommodating groove 25 will directly limit the first slider 26 and the second slider 27, so that they slide along the specified route, the first slider 26 will directly drive the driven plate 31 to move, and then the screening frame 12 will slide, and the second slider 27 will be fixedly connected to the receiving frame 10, driving the receiving frame 10 to slide, so that the receiving frame 10 and the screening frame 12 can slide in the similar direction and the distant direction, and the large impurities of the Chinese medicinal materials are screened by the first screening net 13 and the second screening net 14, and then the Chinese medicinal materials that meet the standards will directly fall into the inside of the receiving frame 10, and the Chinese medicinal materials are weighed by the weighing module. At the same time, the inclined design of the guide plate 11 can realize that the weighed medicinal materials are accumulated on one side of the receiving frame 10, and at the same time After the receiving frame 10 is shaken, it will generate thrust on the Chinese medicinal materials, and then the Chinese medicinal herbs will pass from the inside of the extension sleeve 20 to the inside of the feeding pipe 19, so that the weighed Chinese medicinal materials can be discharged. Then, the large impurities in the screening frame 12 are guided by the inclined surface of the first screening net 13, and finally slide from the inside of the through groove 16 to the inside of the fixed box 6 for unified collection. When passing through the inside of the through groove 16, the design of the second baffle 21 can prevent large impurities from falling into the receiving frame 10, so that the standard and non-standard medicinal materials can be separated quickly. Since part of the feeding pipe 19 is bent, it will cause congestion when some Chinese medicinal materials are discharged. By arranging belts on the outside of the two sets of rotating wheels 57, the horizontal axis 58 can be rotated.Then the crank 59 drives the swing rod 60 to rotate, and the design of the connecting sleeve 61 will limit the top of the swing rod 60, so that the rotation of the swing rod 60 is converted into lifting movement, and then the impact rod 50 is pulled, and the second spring 51 is compressed. As the impact rod 50 moves up and down, it hits the flat plate 55, and then the flat plate 55 is lifted up at the same time, stretching the third spring 54. When the impact rod 50 falls, the third spring 54 is reset, so that the flat plate 55 is shaken, and then the extrusion sleeve 56 knocks on the feeding pipe 19, thereby generating a vibration force to break up the congested Chinese medicinal materials and facilitate discharge.
