Technical Field
[0001] This utility model relates to the field of medicinal plant screening technology, and in particular to a medicinal plant screening and processing device. Background Technology
[0002] Medicinal plant screening refers to the process of selecting plants with medicinal or potential medicinal value from a large pool of plant resources using scientific methods and techniques. This process typically involves multiple steps and technical means to ensure that the selected plants meet medicinal requirements.
[0003] Traditional screening equipment often suffers from low screening efficiency, material clogging of screens, and insufficient screening accuracy, making it difficult to meet the demands of modern industry for refined material processing. For example, in ore processing, it is necessary to separate ores of different particle sizes to improve subsequent beneficiation efficiency; in food production, raw materials need to be precisely screened to ensure product quality uniformity. Therefore, the development of a high-efficiency, stable, and highly accurate screening device is urgently needed.
[0004] To address the pain points of existing screening equipment, this device is designed to meet the following requirements: First, it improves screening efficiency and reduces material blockage through an innovative vibration structure; second, it adopts a cross-discharge and multi-layer screening design to improve screening accuracy and achieve precise material classification; third, it optimizes the screen frame installation method to enhance the stability and durability of the equipment; and fourth, it simplifies the operation process by using a control switch to start and stop the equipment and regulate its operation, reducing the difficulty of manual operation and maintenance costs, so as to adapt to the diverse screening needs of different industrial scenarios. Utility Model Content
[0005] The purpose of this invention is to provide a medicinal plant screening and processing device that solves the problem in the background art of having a transmission structure that is difficult to meet complex stirring trajectories, thereby enhancing the contact between the dough and the kneading components, promoting gluten formation, and ensuring the uniformity of the dough.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a medicinal plant screening and processing device, comprising a base, the base being hollow, two fixing rods fixedly installed on both sides of the upper surface of the base, two crossbars fixedly installed at the top of the two fixing rods, a sieve frame movably installed on the side of the two crossbars close to each other, a screening component installed inside the sieve frame, a protective shell fixedly installed on the upper surface of the base, two eccentric wheels rotatably connected to both sides of the protective shell, a vibration component installed inside the protective shell, and a control switch installed on the side of the protective shell away from the fixing rods.
[0007] The screening component includes a chute, with two chutes formed on the two crossbars, two wheel grooves formed inside the two chutes, two rollers rotatably connected inside the two wheel grooves, and two convex shafts rotatably connected to the two rollers on their adjacent sides, with the two convex shafts respectively fixedly installed on both sides of the screen frame.
[0008] The screen frame is equipped with a screen mesh, which is made of metal. The screen mesh has a discharge port one on the side away from the protective shell. The screen mesh is inclined. A base plate is fixedly installed at the bottom of the screen mesh. The base plate has a discharge port two on the side near the discharge port one. The base plate is inclined. The discharge port one and discharge port two are arranged intersectingly.
[0009] The vibration component includes a motor. The motor is fixedly installed on the protective shell near the control switch. The motor is electrically connected to the control switch. A spindle is rotatably connected inside the protective shell. The two ends of the spindle are fixedly connected to two eccentric wheels, respectively.
[0010] The spindle is externally fixedly equipped with a disc tooth, and a gear is meshed with one side of the bottom end of the disc tooth. A rotating shaft is fixedly installed inside the gear. One end of the rotating shaft is fixedly connected to the output end of the motor, and the end of the rotating shaft away from the motor is rotatably connected to the protective shell.
[0011] Among them, push-pull rods are rotatably connected to the two eccentric wheels on opposite sides. There are two push-pull rods. Two fixed plates are rotatably connected to the ends of the two push-pull rods away from the two eccentric wheels. A fixed shaft is fixedly installed on the side of the two fixed plates that is close to each other. The fixed shaft passes through the two fixed plates and is rotatably connected to the two push-pull rods. The ends of the two fixed plates away from the two push-pull rods are fixedly connected to the screen frame.
[0012] This utility model discloses a medicinal plant screening and processing device. The device is highly innovative in its sieve frame installation and vibration drive. The sieve frame, connected to rollers on both sides by convex shafts, is embedded in the sliding grooves of the crossbar and the internal wheel grooves, forming a double-track rolling guide structure. This ensures stable operation of the sieve frame during vibration, reducing shaking and wear, and extending the equipment's service life. The vibration component employs an eccentric wheel combined with a push-pull rod design. The motor drives the spindle to rotate through gear and disc gear transmission, which in turn drives the eccentric wheel to rotate. The rotation of the eccentric wheel transmits the rotational force to the sieve frame through the push-pull rod, causing the sieve frame to vibrate regularly along the roller track. This structure, combining rolling guidance with eccentric wheel vibration, ensures both the stability of the sieve frame vibration and enhances the vibration effect. Compared to traditional screening equipment with fixed screen frames, this device significantly improves screening efficiency and material throughput. Its discharge design is ingenious and practical, with both the screen and base plate inclined, and discharge ports one and two arranged in a crisscross pattern. The inclined screen facilitates the material sliding towards discharge port one under vibration, completing the initial screening. The inclined base plate below the screen and discharge port two can collect impurities and particles screened out by the screen, achieving secondary screening and classified discharge. This multi-layer screening and cross-discharge design can simultaneously process materials of different particle sizes, avoiding mixing of large and small particles and improving screening accuracy and material separation purity. Furthermore, the metal screen is robust and durable, adaptable to various working conditions, and meets the stringent material screening requirements of different industries.

The push-pull rod 20 periodically pushes and pulls the fixed plate 21 on one side of the screen frame 4, so that the screen frame 4 reciprocates along the roller 7 track in the slide groove 5 of the crossbar 3. The material to be screened is poured into the screen frame 4.
