Technical Field
[0001] The present application relates to the field of Chinese medicine preparation, and in particular to a Chinese medicine crushing and screening device. Background Art
[0002] In the modern preparation process of traditional Chinese medicine, when it is necessary to test the components, effects and other indicators of traditional Chinese medicine, it is usually necessary to crush and sieve the traditional Chinese medicine to obtain the powdered traditional Chinese medicine. However, the existing operation methods and equipment mostly separate the crushing and screening processes. After the traditional Chinese medicine is crushed, it is screened by other devices. The operation steps of this method are too cumbersome, which makes the operator's workload large and leads to low operation efficiency. It is not convenient for continuous and long-term crushing and screening operations.
[0003] For example, a grinding and screening device for inspecting Chinese herbal medicine slices with the publication number CN212791263U has a structure including a base, a cylinder, a buckle, a thick-walled section, a thin-walled section, a machine head, a stirring shaft, a blade, a sieve bucket, a screen, a joint, a motor, an eccentric shaft, and a connecting rod, wherein the cylinder is erected in the base, the cylinder is fixedly connected to the base by a buckle, the cylinder includes a thick-walled section and a thin-walled section connected to each other from top to bottom, the machine head is fixedly connected to the upper port of the cylinder, a stirring shaft is connected to the lower end of the machine head, a number of blades are fixedly connected to the stirring shaft, the sieve bucket is located in the thin-walled section, a screen is connected to the sieve bucket, a joint is fixedly connected to the bottom end of the sieve bucket, the motor is fixedly connected in the base, an eccentric shaft is connected to the motor, and the eccentric shaft is connected to the joint through a connecting rod. The above-mentioned screening device can only improve the efficiency of the operation by performing grinding and screening simultaneously, and screens the material by making a longitudinal reciprocating motion in the thin-walled section. However, it cannot solve the problem that the relatively fine and dry Chinese medicine powder is deposited on the filter plate and the inner wall of the barrel, and is inconvenient to clean. Therefore, the present application designs a Chinese medicine crushing and screening device that can simultaneously crush and screen Chinese medicinal materials, and clean and collect the residual powder on the filter screen and the inner wall of the barrel after the crushing is completed.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] See also Figures 1 to 6 As shown, the utility model provides the following technical solutions: a traditional Chinese medicine crushing and screening device, comprising a barrel body 1, a collecting tank 2, an inner barrel 3, a crushing mechanism 4 and a cleaning mechanism 5 for blowing and cleaning the barrel body 1 and the inner barrel 3 after the crushing is completed; the inner barrel 3 is sleeved inside the barrel body 1, the upper side of the inner barrel 3 is fixedly connected to the inner wall of the barrel body 1, the inner barrel 3 is a filter structure with an upper through-hole, the crushing mechanism 4 is plugged into the cleaning mechanism 5, the upper end of the barrel body 1 is detachably connected to a barrel cover 6, the barrel cover 6 is plugged into the crushing mechanism 4, a one-way bearing 7 is provided in the crushing mechanism 4, the inner ring of the one-way bearing 7 is fixedly connected to the crushing mechanism 4, and the outer ring of the one-way bearing 7 is fixedly connected to the cleaning mechanism 5, the crushing mechanism 4 crushes the medicinal materials in the inner barrel 3 by rotating, and the crushing mechanism 4 drives the cleaning mechanism 5 to rotate by reverse rotation through the locking of the one-way bearing 7 to perform spiral air supply to the barrel body 1 and the inner barrel 3, thereby blowing and cleaning the inner wall of the barrel body 1 and the inner barrel 3.
[0023] Place the medicinal materials to be crushed in the inner cylinder 3, then connect the barrel cover 6 to the crushing mechanism 4 and the cleaning mechanism 5 and install it on the barrel body 1. Start the crushing mechanism 4 to rotate forward to crush the Chinese medicinal materials in the inner cylinder 3. The inner cylinder 3 made of filter material will filter the crushed medicine powder into the barrel body 1. When the crushing mechanism 4 rotates forward, the one-way bearing 7 will not drive the cleaning mechanism 5 to rotate.
[0024] See also Figure 1 The barrel 1 is an inverted cone structure with an opening at the bottom. The barrel 1 is connected to the collecting tank 2 through the opening. The powdered medicine that has been crushed into the barrel 1 will naturally slide down to the collecting tank 2 through the inverted cone barrel 1.
[0025] As another example, Figure 2 、 Figure 3 、 Figure 5 as well as Figure 6 As shown, the barrel cover 6 comprises an outer cover 61 and an inner cover 62. The outer cover 61 is threadedly connected to the upper portion of the barrel body 1, and the inner cover 62 is fixedly connected to the outer cover 61 via a connecting rod 63. The inner cover 62 is hollow to facilitate the passage of the crushing mechanism 4. A first connecting post 64 is provided on the upper portion of the outer cover 61, and a second connecting post 65 is provided on the upper portion of the inner cover 62. By placing the outer cover 61 on the barrel body 1 and rotating the outer cover 61, the crushing mechanism 4 and the cleaning mechanism 5 are installed. The second connecting post 65 is a bearing structure.
[0026] See also Figure 2 、 Figure 5 as well as Figure 6 The pulverizing mechanism 4 includes a motor 41, a rotating rod 42, and a pulverizing blade assembly 43. The motor 41 is plugged into the cleaning mechanism 5, the rotating rod 42 is plugged into the output shaft of the motor 41, the rotating rod 42 is fixedly connected to the inner ring of the one-way bearing 7, and the pulverizing blade assembly 43 is plugged into the end of the rotating rod 42 away from the motor 41. After the medicinal materials are placed in the inner barrel 3 and the barrel cover 6 is installed, the motor 41 is started to rotate forward so that the output end of the motor 41 drives the rotating rod 42 to rotate, thereby driving the pulverizing blade assembly 43 to rotate and pulverize the medicinal materials in the inner barrel 3. After the pulverization is completed, the motor 41 slowly reverses to drive the rotating rod 42 to reverse, thereby driving the one-way bearing 7 to lock, so that the one-way bearing 7 drives the cleaning mechanism 5 to rotate and clean the interior of the barrel body 1 and the inner barrel 3.
[0027] As another example, Figures 2 to 6 As shown, the cleaning mechanism 5 includes an inner turntable 51, a fixed disk 52, and an air supply assembly 53. The fixed disk 52 is fixedly connected to the outer cover 61 via a first connecting post 64. The inner turntable 51 is rotatably connected to the inner cover 62 via a second connecting post 65. The air supply assembly 53 is disposed within the inner turntable 51 and extends vertically through the inner turntable 51. After the medicinal materials are crushed, the reverse rotation of the motor 41 drives the one-way bearing 7 to lock, thereby driving the inner turntable 51 to rotate, causing the inner turntable 51 to drive the air supply assembly 53 to perform a circular motion.
[0028] See also Figure 4 A fine rack 521 is provided on the inner wall of the fixed disk 52 , the motor 41 is plugged into the upper part of the fixed disk 52 , and the output shaft of the motor 41 passes through the fixed disk 52 .
[0029] See also Figure 4 and Figure 5 A through hole 511 is opened in the middle of the inner turntable 51, and the outer ring of the one-way bearing 7 is fixedly connected to the inner wall of the inner turntable 51 through the through hole 511.
[0030] See also Figures 4 to 6The air supply assembly 53 includes a fan 531 and a gear 532. The fan 531 is rotatably connected to the inner wall of the inner turntable 51. The lower end of the gear 532 is fixedly connected to the fan 531. The gear 532 protrudes to the upper end of the inner turntable 51 and meshes with the rack 521. The air supply assembly 53 is provided with two sets of air supply assemblies 53, which are symmetrically arranged on the inner turntable 51. The gear 532 has a plurality of small holes for ventilation. When the inner turntable 51 rotates, the gear 532 and the fan 531 are driven to perform a circular motion. Due to the meshing with the rack 521 on the fixed disk 52, the gear 532 rotates during the circular motion, thereby driving the fan 531 to rotate. The rotation of the fan 531 generates an airflow that impacts the inner wall of the barrel 1 and the inner cylinder 3. Since the fan 531 also performs a circular motion, the airflow also forms a spiral downward airflow, disturbing the deposited powder and entraining it into the collection tank 2.
[0031] Working principle: When in use, the barrel cover 6 is rotated to remove the barrel body 1, the medicinal materials to be crushed are placed in the inner barrel 3, and then the barrel cover 6 is reinstalled on the barrel body 1, and the motor 41 is started so that the motor 41 drives the rotating rod 42 to rotate forward, thereby driving the crushing knife group 43 to rotate and crush the medicinal materials. The crushed medicinal powder passes through the filter structure of the inner barrel 3 and falls into the inside of the barrel body 1 and naturally slides into the collection tank 2 through the inverted cone-shaped barrel body 1. After the crushing operation is completed, the motor 41 is started to reverse, so that the motor 41 drives the rotating rod 42 to reverse and then drives the single The bearing 7 is locked, so that the rotating rod 42 drives the inner turntable 51 to rotate through the one-way bearing 7, so that the gear 532 and the fan 531 make a circular motion. The engagement of the gear 532 with the fixed disk 52 makes the gear 532 rotate while making a circular motion, thereby driving the fan 531 to rotate, and the spiral airflow disturbs and impacts the medicine powder deposited on the inner wall of the barrel body 1 and the inner cylinder 3, so that the participating medicine powder enters the collection tank 2 under the influence of the airflow. After the cleaning is completed, the collection tank 2 can be removed to complete the collection of the medicine powder.
[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
