DETAILED DESCRIPTION

[0018] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0019] See also Figure 1-Figure 8 As shown, the present invention provides a drum screening device for processing Chinese medicinal materials, comprising a housing 1, a drum 4 is rotatably connected inside the housing 1, a plurality of through holes 16 are opened on the surface of the drum 4, and a rotating assembly 3 is provided on the housing 1 for rotating the drum 4; A cleaning vibration mechanism 25 is fixedly connected in the housing 1, which is used to vibrate the roller 4 and clear the through hole 16 of the roller 4. A crushing assembly 18 is fixedly connected to the roller 4, and when the roller 4 rotates, the protrusions in the roller 4 that cannot pass through the through hole 16 can be crushed; A grille switch door 6 is provided at one end of the drum 4 , and a grille 17 is fixedly connected to the other end. A fan 2 corresponding to the grille 17 is fixedly connected to the housing 1 .

[0020] During the collection and preliminary processing of medicinal materials, a large amount of dirt usually adheres to the surface of the medicinal materials. At present, some of the methods used to clean the dirt on the surface of medicinal materials are manual cleaning, which is inefficient and the cleaning effect is greatly affected by human factors, making it difficult to ensure the consistency of cleaning. Some existing cleaning equipment mainly focuses on water washing of medicinal materials, and does not have a special function for effectively screening the dirt on the surface of medicinal materials. If most of the dirt can be screened out before water washing, it can not only reduce the waste of water resources, but also reduce the burden of subsequent water washing links and improve the overall cleaning efficiency. At the same time, traditional screening methods may cause damage to medicinal materials and affect the quality of medicinal materials.

[0021] The drum 4 is rotated by the rotating component 3 to make the medicinal materials tumble in the drum 4. During the rotation of the drum 4, the through hole 16 can be cleaned by the cleaning vibration mechanism 25 to avoid blockage of the through hole 16. At the same time, the drum 4 is vibrated to improve the screening effect. The soil blocks can be crushed by the crushing component 18 to improve the screening efficiency and screening effect. The cleaning vibration mechanism 25 and the crushing component 18 can follow the rotation of the drum 4 in a linked manner, and do not need a separate actuator to drive them, so that the device has better stability, is less prone to errors, and is useful in reducing manufacturing costs.

[0022] As an optional embodiment, an opening 7 and an air inlet 11 are respectively provided on both sides of the shell 1, and the air inlet 11 corresponds to the fan 2. The fan 2 blows out the dust in the drum 4. The air inlet 11 can be provided to blow out the dust that falls into the shell 1.

[0023] The rotating assembly 3 includes two outer gear rings 10, which are fixedly connected to the two sides of the surface of the drum 4, and two rotating shafts 18 and two rotating shafts 12 are rotatably connected to the two sides of the shell 1. The surfaces of the rotating shaft 18 and the rotating shaft 2 12 are fixedly connected with a gear 19 and a gear 2 13, respectively. The two gears 19 and the two gears 2 13 are meshed with the two outer gear rings 10, respectively. A motor 14 is fixedly connected to the shell 1, and the motor 14 is fixedly connected to one end of the two rotating shafts 12; By rotating one of the gears 2 13 through the motor 14 , the two gears 2 13 cooperate with the two gears 1 9 to support the drum 4 and rotate the drum 4 .

[0024] The outer gear ring 10 is located outside the shell 1, which can prevent soil in the medicinal materials from falling into the outer gear ring 10 and affecting the operation of the rotating component 3. Snap rings 15 are fixedly connected on both sides of the outer gear ring 10 to limit the position of gear 1 9 and gear 2 13.

[0025] A drawer 5 corresponding to the drum 4 is placed at the bottom of the inner wall of the shell 1, and the drawer 5 is used to store the screened soil.

[0026] 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 spring 28 is sleeved on the surface of the telescopic rod 27, and the two ends of the spring 28 are respectively fixedly connected to the connecting frame 26 and the connecting plate 29. A plurality of 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 holes 16; The telescopic rod 27 cooperates with the spring 28 to continuously push the top block 30 downward. After the top block 30 enters the through hole 16, the dust blocked in the through hole 16 can be cleared. As the drum 4 rotates, the top block 30 will break away from the through hole 16 and contact the surface of the drum 4 and then enter another through hole 16. In this process, the top block 30 can expand with the through hole 16, thereby generating vibration and improving the screening efficiency.

[0027] The portion of the top block 30 inserted into the through hole 16 is arc-shaped, and a plurality of fixing plates 31 are fixedly connected to the connecting plate 29 . The fixing plates 31 are in contact with the surface of the drum 4 . The arc-shaped design facilitates the separation of the top block 30 from the through hole 16 .

[0028] The crushing assembly 18 includes a plurality of fixed rings 19 fixedly connected to the inner wall of the drum 4 along the axis of the drum 4, and a plurality of connecting rods 21 are slidably connected between the plurality of fixed rings 19, each connecting rod 21 passes through all the fixed rings 19, and a plurality of movable rings 20 are fixedly connected between the plurality of connecting rods 21, and the plurality of movable rings 20 and the fixed rings 19 are alternately arranged, the connecting rod 21 passes through the grille 17 and is fixedly connected with a hemispherical head 22, a spring 23 is sleeved on the connecting rod 21, and the two ends of the spring 23 are respectively fixedly connected to the grille 17 and the hemispherical head 22, the connecting rod 21 is slidably connected to the grille 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 an inclined surface, and when the hemispherical head 22 passes through the baffle 24, the hemispherical head 22 is close to the grille 17; When the hemispherical head 22 passes through the baffle 24, the hemispherical head 22 cooperates with the baffle 24 to push the connecting rod 21. After the hemispherical head 22 is separated from the baffle 24, the spring 1 23 can reset the connecting rod 21. Therefore, when the drum 4 rotates, the connecting rod 21 can continuously move back and forth, and the movable circle 20 is driven to approach the fixed circle 19 through the connecting plate 21. The movable circle 20 cooperates with the fixed circle 19 to crush the soil blocks, and the crushing assembly 18 will not damage the medicinal materials during the process of crushing the soil blocks. The distance between the movable circle 20 and the fixed circle 19 can be calibrated according to needs. Specifically, the distance between the movable circle 20 and the fixed circle 19 can be set to half the diameter of the through hole 16. Such a distance setting is sufficient to crush the soil blocks, and the medicinal materials are not between the movable circle 20 and the fixed circle 19. Even if the roots and stems of some medicinal materials are located between the movable circle 20 and the fixed circle 19, since the movable circle 20 and the fixed circle 19 will not fit together, the roots and stems of the medicinal materials will not be clamped by the movable circle 20 and the fixed circle 19.

[0029] The fixed ring 19 and the movable ring 20 are respectively 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 drum 4 .

[0030] By adopting the above structure, the medicinal materials are placed in the drum 4, and the drum 4 is rotated by the rotating component 3 to make the medicinal materials roll in the drum 4, so as to screen the soil on the medicinal materials. During the rotation of the drum 4, the through hole 16 can be cleaned by the cleaning vibration mechanism 25 to avoid clogging of the through hole 16. At the same time, the drum 4 is vibrated to improve the screening effect. If the volume of some soil blocks is larger than the through hole 16, these soil blocks can be crushed by the crushing component 18 to improve the screening efficiency and screening effect. At the same time, the fan 2 can blow the fine dust on the surface of the medicinal materials and in the drum 4 out of the drum 4.

[0031] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
