Description

Technical Field

[0001] This utility model belongs to the field of medicinal material processing equipment, and in particular, it is a medicinal material screening device. Background Technology

[0002] In the process of processing medicinal materials, screening is an extremely important step, which aims to remove impurities and foreign objects from the medicinal materials and classify them according to characteristics such as size, shape, and density. Traditional medicinal material screening devices can meet basic usage requirements, but their ability to prevent clogging is weak. If the feed inlet is blocked, the medicinal materials cannot enter the screening device evenly and continuously. The screening equipment cannot operate at full capacity and may even need to be stopped frequently to clear the blockage, resulting in a significant decrease in overall screening efficiency.

[0003] A search revealed Chinese patent document (authorization announcement number CN220804263U). This utility model relates to the technical field of medicinal material screening, specifically a medicinal material screening device. The device includes a screening box with a pulley plate on its inner sidewall near the top and a sliding groove on the top. This utility model designs a medicinal material screening device utilizing a screening box, a shaking machine, a powder collection cup, a powder screening cabinet, a powder sieve, a receiving screening cabinet, a receiving sieve, a passing screening cabinet, a screening layer, a passing box, an inlet screening cabinet, an inlet sieve, and an inlet. The medicinal materials are poured into the inlet of the passing box. When the medicinal materials are fed into the feeding sieve of the feeding screening cabinet, the shaking machine is activated. The shaking of the shaking machine causes the medicinal materials to fall through the wire mesh of the feeding sieve and enter the material screening cabinet inside the screening box, completing the screening of each layer. This effectively solves the shortcomings of traditional medicinal material screening devices that are not fine enough. This device can meet basic usage requirements. However, the feeding anti-blocking ability is weak. If the feeding port is blocked, the medicinal materials cannot enter the screening device evenly and continuously. The screening equipment cannot operate at full capacity and may even need to be stopped frequently to clean the blockage, resulting in a significant decrease in overall screening efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a medicinal material screening device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a medicinal material screening device, comprising a screening box for preventing medicinal materials from flying out during screening, an anti-blocking box installed on the side of the screening box, and a feeding hopper for medicinal materials to enter connected to the top of the anti-blocking box;

[0006] Both sides of the anti-clogging box are provided with square grooves, and springs are connected inside the two square grooves. One end of the spring is connected to a moving block. The moving block is slidably disposed inside the square groove. A rotating shaft is rotatably connected inside the moving block. A V-shaped anti-clogging plate for contacting the incoming medicinal material is installed on the outer periphery of the rotating shaft. The surface of the V-shaped anti-clogging plate is provided with multiple feed holes.

[0007] Preferably, the vertical inner wall of the anti-blocking box is provided with a guide groove for the sliding of the moving block, and the vertical inner wall of the anti-blocking box is equipped with a stop bar for cooperating with the V-shaped anti-blocking plate.

[0008] Preferably, the bottom of the anti-blocking box is rotatably equipped with a spiral conveyor shaft for conveying medicinal materials.

[0009] Preferably, a motor is mounted on the side of the screening box, and the output of the motor is connected to a belt drive structure via a coupling.

[0010] Preferably, a main gear is mounted on the side of the belt drive structure, and a secondary gear is meshed with the outer periphery of the main gear.

[0011] Preferably, a rotating shaft is connected to the side of the main gear, and the end of the rotating shaft away from the main gear is connected to the end of the screw conveyor shaft. A fan blade for blowing away dust from the surface of the medicinal materials is installed on the side of the auxiliary gear.

[0012] Preferably, a screening barrel for screening medicinal materials is installed on the outer periphery of the rotating shaft, and a conveyor belt for transporting the screened medicinal materials is provided inside the screening box.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This medicinal herb screening device benefits from the structure of the V-shaped anti-clogging plate. The medicinal herbs to be screened are put into the anti-clogging box through the feed hopper. The herbs come into contact with the edge of the V-shaped anti-clogging plate and enter the bottom of the anti-clogging box along the edge of the V-shaped anti-clogging plate. The V-shaped anti-clogging plate can be deflected to prevent blockage. Compared with the weak anti-clogging ability of traditional medicinal herb screening devices, this structure improves the anti-clogging ability of the feed and prevents the feed inlet from being blocked. The herbs can enter the screening device evenly and continuously, reducing downtime for cleaning blockages and greatly improving the overall screening efficiency.

[0015] This medicinal herb screening device benefits from the structure of the baffle bar. When too much medicinal material enters the feed hopper, the material presses down on the V-shaped anti-blocking plate. The V-shaped anti-blocking plate drives the rotating shaft to shift within the moving block, preventing the sudden influx of too much material from clogging the feed inlet. The material presses down on the V-shaped anti-blocking plate, the moving block, and the spring. One side of the V-shaped anti-blocking plate contacts the baffle bar, causing the V-shaped anti-blocking plate to shift. This increases the amount of material entering while preventing blockage.

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0026] like Figures 1 to 5The medicinal material screening device shown includes a screening box 1 for preventing medicinal materials from flying out during screening, an anti-blocking box 3 installed on the side of the screening box 1, and a feeding hopper 301 for medicinal materials to enter the top of the anti-blocking box 3.

[0027] Both sides of the anti-blocking box 3 are provided with square grooves 4. Springs 401 are connected inside the two square grooves 4. One end of the spring 401 is connected to a moving block 402. The moving block 402 is slidably disposed inside the square groove 4. A rotating shaft 403 is rotatably connected inside the moving block 402. A V-shaped anti-blocking plate 404 for contacting the incoming medicinal materials is installed on the outer periphery of the rotating shaft 403. The surface of the V-shaped anti-blocking plate 404 is provided with multiple feed holes 405. When too much medicinal material enters the feed hopper 301, the medicinal material presses down on the V-shaped anti-blocking plate 404. The V-shaped anti-blocking plate 404 drives the rotating shaft 403 to shift within the moving block 402 to prevent the sudden influx of too much medicinal material from blocking the feed inlet. The medicinal material presses down on the V-shaped anti-blocking plate 404, the moving block 402 and the spring 401. One side of the V-shaped anti-blocking plate 404 contacts the abutment bar 407. The V-shaped anti-blocking plate 404 shifts, which can both increase the amount of medicinal material entering and prevent blockage.

[0028] The vertical inner wall of the anti-blocking box 3 is provided with a guide groove 406 for the sliding of the moving block 402. The vertical inner wall of the anti-blocking box 3 is also provided with a stop bar 407 for cooperating with the V-shaped anti-blocking plate 404. The bottom of the anti-blocking box 3 is rotatably provided with a spiral conveying shaft 201 for conveying medicinal materials. The spiral conveying shaft 201 has spiral conveying blades, which are usually made of metal sheet through processing and have a continuous spiral shape. The diameter, pitch and blade thickness of the spiral line are designed according to different conveying requirements and material characteristics. The medicinal materials to be screened are put into the anti-blocking box 3 through the feed hopper 301. The medicinal materials contact the edge of the V-shaped anti-blocking plate 404 and enter the bottom of the anti-blocking box 3 along the edge of the V-shaped anti-blocking plate 404.

[0029] A motor 101 is mounted on the side of the screening box 1. The output of the motor 101 is connected to a belt drive structure 102 via a coupling. The belt drive structure 102 transmits power and motion by means of the friction between the belt and the pulley. When the driving pulley rotates under the drive of the motor or other power source, the friction between the belt and the pulley causes the belt to move along with the pulley, thereby driving the driven pulley to rotate and realizing the transmission of power. In this process, the belt acts as a connector between the driving and driven pulleys and adapts to different working conditions through its own elastic deformation. A main gear 103 is mounted on the side of the belt drive structure 102. A secondary gear 104 is meshed with the outer periphery of the main gear 103. A rotating shaft 2 is connected to the side of the main gear 103. The end of the rotating shaft 2 away from the main gear 103 is connected to the end of the screw conveyor shaft 201. A fan blade 105 for blowing away dust from the surface of the medicinal materials is mounted on the side of the secondary gear 104. A screening bucket 106 for screening the medicinal materials is mounted on the outer periphery of the rotating shaft 2. The screening box 1 is equipped with a conveyor belt 107 for transporting the screened medicinal materials. When the motor 101 is turned on, the motor 101 drives the movable part of the belt drive structure 102 to rotate. The belt drive structure 102 drives the main gear 103 and the auxiliary gear 104 to rotate. The main gear 103 drives the rotating shaft 2, the screening barrel 106 and the screw conveyor shaft 201 to rotate. The screw conveyor shaft 201 transports the medicinal materials at the bottom of the anti-clogging box 3 into the screening barrel 106. The screening barrel 106 screens the medicinal materials. The auxiliary gear 104 drives the fan blade 105 to rotate. The fan blade 105 blows air into the medicinal materials in the screening barrel 106 to blow away the dust on the surface of the medicinal materials. The screened medicinal materials can fall onto the conveyor belt 107 through the holes of the screening barrel 106. The conveyor belt 107 transports the screened medicinal materials.

[0030] Working principle

[0031] In use, the medicinal material screening device first places the medicinal materials to be screened into the anti-blocking box 3 through the feed hopper 301. The medicinal materials contact the edge of the V-shaped anti-blocking plate 404 and enter the bottom of the anti-blocking box 3 along the edge of the V-shaped anti-blocking plate 404. The motor 101 is then turned on, which drives the movable part of the belt drive structure 102 to rotate. The belt drive structure 102 drives the main gear 103 and the auxiliary gear 104 to rotate. The main gear 103 drives the rotating shaft 2, the screening barrel 106, and the screw conveyor shaft 201 to rotate. The screw conveyor shaft 201 transports the medicinal materials from the bottom of the anti-blocking box 3 into the screening barrel 106, where the screening barrel 106 screens the medicinal materials. The auxiliary gear 104 drives the fan blade 105 to rotate, and the fan blade 105 transports the medicinal materials from the bottom of the anti-blocking box 3 into the screening barrel 106. The herbs inside the screening barrel 106 are blown by air to remove dust from their surface. The screened herbs fall through the holes in the screening barrel 106 onto the conveyor belt 107, which transports them. When too many herbs enter the feed hopper 301, the herbs press down on the V-shaped anti-blocking plate 404. The V-shaped anti-blocking plate 404 drives the rotating shaft 403 to shift within the moving block 402, preventing the sudden influx of herbs from clogging the feed inlet. The herbs press down on the V-shaped anti-blocking plate 404, the moving block 402, and the spring 401. One side of the V-shaped anti-blocking plate 404 contacts the abutment bar 407, causing the V-shaped anti-blocking plate 404 to shift. This increases the amount of herbs entering while preventing blockage.
