Description

Technical Field

[0001] This invention relates to the field of medicinal material processing technology, and specifically to a drum screening device for processing Chinese medicinal materials. Background Technology

[0002] After medicinal herbs are dug up from the field, they are often covered with a lot of soil, which needs to be removed by a screening device. Current technology often uses a drum screen for this purpose; however, the mesh of existing drum screens is easily clogged, especially by sticky soil. Some clods of soil cannot pass through the mesh at all, and the external force generated by the drum's rotation is insufficient to break up the already compacted clods.

[0003] Existing technologies also improve screening efficiency and crush soil clods by setting a stirring roller inside the drum. While this does improve screening efficiency and crush soil clods, the high-speed rotating stirring roller can easily damage the medicinal materials, and it still cannot solve the problem of the drum mesh being clogged. Summary of the Invention

[0004] The purpose of this invention is to provide a drum screening device for processing Chinese medicinal materials in order to solve the above-mentioned problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The present invention provides a drum screening device for processing Chinese medicinal materials, comprising a housing, a drum rotatably connected inside the housing, a plurality of through holes being formed on the surface of the drum, and a rotating assembly being provided on the housing for rotating the drum;

[0007] A cleaning vibration mechanism is fixedly connected inside the housing to vibrate the drum and clear the through hole of the drum. A crushing component is fixedly connected to the drum. When the drum rotates, it can crush soil clods inside the drum that cannot pass through the through hole.

[0008] One end of the roller is equipped with a grille switch door, and the other end is fixedly connected to a grille. A fan corresponding to the grille is fixedly connected to the housing.

[0009] The above-mentioned drum screening device for processing Chinese medicinal materials involves placing the medicinal materials into the drum and rotating the drum through a rotating component, causing the medicinal materials to tumble inside the drum, thereby screening out the soil on the medicinal materials. During the rotation of the drum, a cleaning vibration mechanism can clean the through holes to prevent them from becoming blocked. At the same time, the vibration of the drum improves the screening effect. If some soil clumps are larger than the through holes, the crushing component can crush these soil clumps, improving the screening efficiency and effect. Meanwhile, a blower can blow out fine dust from the surface of the medicinal materials and inside the drum.

[0010] Preferably, the housing has an opening and an air inlet on each side, and the air inlet corresponds to the fan.

[0011] Preferably, the rotating assembly includes two external gear rings, which are fixedly connected to both sides of the roller surface. Two rotating shafts and two rotating shafts are rotatably connected to both sides of the housing. Gears are fixedly connected to the surfaces of rotating shafts and rotating shafts, respectively. Gears mesh with the two external gear rings. A motor is fixedly connected to the housing, and the motor is fixedly connected to one end of one of the two rotating shafts.

[0012] Preferably, the external gear ring is located outside the housing, and retaining rings are fixedly connected to both sides of the external gear ring for limiting the movement of gear one and gear two.

[0013] Preferably, a drawer corresponding to the roller is placed at the bottom of the inner wall of the housing.

[0014] Preferably, the cleaning vibration mechanism includes a connecting frame, which is fixedly connected to the top of the inner wall of the housing. The connecting frame is connected to a connecting plate via two vertically arranged telescopic rods. A second spring is sleeved on the surface of the telescopic rod, and the two ends of the second spring are fixedly connected to the connecting frame and the connecting plate, respectively. Several top blocks are fixedly connected along a straight line on the connecting plate, and the top blocks are adapted to the through holes.

[0015] Preferably, the portion of the top block inserted into the through hole is arc-shaped, and several fixing plates are fixedly connected to the connecting plate, with the fixing plates in contact with the surface of the roller.

[0016] Preferably, the crushing assembly includes several fixed rings fixedly connected to the inner wall of the drum along the drum axis, and several connecting rods slidably connected between the fixed rings. Each connecting rod passes through all the fixed rings, and several movable rings are fixedly connected between the multiple connecting rods. The movable rings and fixed rings are alternately arranged. The connecting rod passes through the grid and is fixedly connected to a hemispherical head. A spring is sleeved on the connecting rod, and the two ends of the spring are fixedly connected to the grid and the hemispherical head respectively. The connecting rod is slidably connected to the grid. A baffle is fixedly connected to the housing, and the side of the baffle corresponding to the hemispherical head is inclined. When the hemispherical head passes through the baffle, the hemispherical head approaches the grid.

[0017] Preferably, the fixed ring and the movable ring are located on both sides of the same through hole edge, and the movable ring is in contact with the inner wall of the roller.

[0018] The beneficial effects are:

[0019] 1. The rotating component rotates the drum, causing the medicinal materials to tumble inside the drum, thereby sieving the soil off the medicinal materials. During the rotation of the drum, the cleaning and vibration mechanism can clean the through holes to prevent them from becoming blocked. At the same time, the vibration of the drum improves the sieving effect. The crushing component can crush these soil clods to prevent them from being unable to pass through the through holes, thereby improving the sieving efficiency and sieving effect.

[0020] 2. The blower can blow out fine dust from the surface of the medicinal materials and inside the drum, further improving the screening effect;

[0021] 3. The moving ring of the crushing component moves in a reciprocating linear motion, while the medicinal materials tumble inside the drum. Therefore, the crushing component will not damage the medicinal materials while crushing the soil.

[0022] 4. The cleaning vibration mechanism and crushing components can move in tandem with the rotation of the drum without the need for a separate actuator, which makes the device more stable, less prone to errors, and helps to reduce manufacturing costs. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0035] See Figures 1-8 As shown, the present invention provides a drum screening device for processing Chinese medicinal materials, including a housing 1, a drum 4 rotatably connected inside the housing 1, a plurality of through holes 16 opened on the surface of the drum 4, and a rotating assembly 3 provided on the housing 1 for rotating the drum 4.

[0036] A cleaning vibration mechanism 25 is fixedly connected inside the housing 1 to vibrate the roller 4 and clear the through hole 16 of the roller 4. A crushing component 18 is fixedly connected on the roller 4. When the roller 4 rotates, it can crush the soil clods inside the roller 4 that cannot pass through the through hole 16.

[0037] One end of the roller 4 is equipped with a grille switch door 6, and the other end is fixedly connected to a grille 17. A fan 2 corresponding to the grille 17 is fixedly connected to the housing 1.

[0038] During the harvesting and initial processing of medicinal herbs, a large amount of dirt usually adheres to their surface. Currently, the removal of this dirt is partly done manually, which is inefficient and highly susceptible to human error, making it difficult to ensure consistent cleaning. Existing cleaning equipment primarily focuses on water washing and lacks a dedicated function for effectively sieving the dirt from the surface. If most of the dirt could be sieved out before washing, it would not only reduce water waste but also lessen the burden on subsequent washing stages, improving overall cleaning efficiency. Furthermore, traditional sieving methods may damage the herbs, affecting their quality.

[0039] Rotating component 3 rotates drum 4, causing the medicinal materials to tumble inside drum 4. During the rotation of drum 4, the cleaning vibration mechanism 25 cleans the through hole 16, preventing it from becoming clogged. At the same time, the vibration of drum 4 improves the screening effect. The crushing component 18 crushes these soil clods, improving screening efficiency and effect. Furthermore, the cleaning vibration mechanism 25 and the crushing component 18 can rotate in conjunction with drum 4 without the need for a separate actuator, making the device more stable, less prone to errors, and helping to reduce manufacturing costs.

[0040] As an optional implementation, the housing 1 has an opening 7 and an air inlet 11 on both sides, and the air inlet 11 corresponds to the fan 2. The fan 2 blows out the dust in the roller 4, and the air inlet 11 can blow out the dust that falls into the housing 1.

[0041] The rotating assembly 3 includes two external gear rings 10, which are fixedly connected to both sides of the surface of the roller 4. Two rotating shafts 1-8 and two rotating shafts 2-12 are rotatably connected to both sides of the housing 1. Gears 1-9 and 2-13 are fixedly connected to the surfaces of rotating shafts 1-8 and 2-12, respectively. The two gears 1-9 and 2-13 mesh with the two external gear rings 10. A motor 14 is fixedly connected to the housing 1, and the motor 14 is fixedly connected to one end of the two rotating shafts 2-12.

[0042] The motor 14 rotates one of the gears 13, and the two gears 13 cooperate with the two gears 9 to support the roller 4 and rotate the roller 4.

[0043] The outer gear ring 10 is located outside the housing 1, which can prevent soil from falling into the outer gear ring 10 and affecting the operation of the rotating component 3. Furthermore, retaining rings 15 are fixedly connected to both sides of the outer gear ring 10 to limit the movement of gear 9 and gear 13.

[0044] The bottom of the inner wall of the housing 1 has a drawer 5 corresponding to the roller 4, which is used to store the sieved soil.

[0045] The cleaning vibration mechanism 25 includes a connecting frame 26, which is fixedly connected to the top of the inner wall of the housing 1. The connecting frame 26 is connected to a connecting plate 29 through two vertically arranged telescopic rods 27. A second spring 28 is sleeved on the surface of the telescopic rods 27, and the two ends of the second spring 28 are fixedly connected to the connecting frame 26 and the connecting plate 29 respectively. Several top blocks 30 are fixedly connected along a straight line on the connecting plate 29, and the top blocks 30 are adapted to the through hole 16.

[0046] The top block 30 can be continuously pushed downward by the telescopic rod 27 and the spring 28. After the top block 30 enters the through hole 16, it can clear the dust blocking the through hole 16. As the drum 4 rotates, the top block 30 will separate from the through hole 16 and contact the surface of the drum 4 before entering another through hole 16. During this process, the top block 30 can expand with the through hole 16, thereby generating vibration and improving screening efficiency.

[0047] The part of the top block 30 that is inserted into the through hole 16 is arc-shaped. Several fixing plates 31 are fixedly connected to the connecting plate 29. The fixing plates 31 are in contact with the surface of the roller 4. The arc-shaped design makes it easy for the top block 30 to detach from the through hole 16.

[0048] The crushing assembly 18 includes several fixed rings 19 fixedly connected to the inner wall of the drum 4 along the axis of the drum 4, and several connecting rods 21 are slidably connected between the fixed rings 19. Each connecting rod 21 passes through all the fixed rings 19, and several movable rings 20 are fixedly connected between the multiple connecting rods 21. The movable rings 20 and the fixed rings 19 are alternately arranged. The connecting rods 21 pass through the grid 17 and are fixedly connected to a hemispherical head 22. A spring 23 is sleeved on the connecting rods 21, and the two ends of the spring 23 are fixedly connected to the grid 17 and the hemispherical head 22 respectively. The connecting rods 21 are slidably connected to the grid 17. A baffle 24 is fixedly connected to the housing 1, and the side of the baffle 24 corresponding to the hemispherical head 22 is inclined. When the hemispherical head 22 passes through the baffle 24, the hemispherical head 22 approaches the grid 17.

[0049] When the hemispherical head 22 passes the baffle 24, the hemispherical head 22 and the baffle 24 cooperate to push the connecting rod 21. After the hemispherical head 22 is separated from the baffle 24, the spring 23 can reset the connecting rod 21. Therefore, when the roller 4 rotates, the connecting rod 21 can move back and forth continuously. The connecting plate 21 drives the movable ring 20 to approach the fixed ring 19. The movable ring 20 and the fixed ring 19 cooperate to crush the soil. In the process of crushing the soil, the crushing component 18 will not damage the medicinal materials. The distance between the movable ring 20 and the fixed ring 19 can be calibrated according to the requirements. Specifically, the distance between the movable ring 20 and the fixed ring 19 can be set to half the diameter of the through hole 16. This distance setting is sufficient to crush the soil, and the medicinal materials are not between the movable ring 20 and the fixed ring 19. Even if the roots and stems of some medicinal materials are between the movable ring 20 and the fixed ring 19, the roots and stems of the medicinal materials will not be crushed by the movable ring 20 and the fixed ring 19 because the movable ring 20 and the fixed ring 19 will not be in contact.

[0050] The fixed ring 19 and the movable ring 20 are located on both sides of the edge of the same through hole 16, and the movable ring 20 is in contact with the inner wall of the roller 4.

[0051] Using the above structure, the medicinal materials are placed into the drum 4, and the drum 4 is rotated by the rotating component 3, causing the medicinal materials to tumble inside the drum 4, thereby sieving the soil off the medicinal materials. During the rotation of the drum 4, the cleaning vibration mechanism 25 can clean the through hole 16 to prevent the through hole 16 from being blocked. At the same time, the vibration of the drum 4 improves the sieving effect. If some soil clods are larger than the through hole 16, the crushing component 18 can crush these soil clods to improve the sieving efficiency and sieving effect. Meanwhile, the blower 2 can blow out the fine dust from the surface of the medicinal materials and inside the drum 4.

[0052] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
