[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This utility model provides a technical solution: a low-noise multi-stage sieving swing arm screen, including an operation box 1 and a guide hopper 2 fixedly installed at the bottom of the operation box 1. The bottom of the guide hopper 2 has a discharge port 3. A drive assembly 4 is movably installed in the upper part of the operation box 1. A sieving assembly 5 is fixedly installed at the bottom of the drive assembly 4. The sieving assembly 5 includes a placement frame 51 and multiple screening frames 52. The placement frame 51 has a placement opening 53 with front and rear openings. The bottom of the inner side of the placement frame 51 and the top of the multiple screening frames 52 are all provided with locking holes 54. The bottom of the multiple screening frames 52 are all fixedly connected with locking posts 55 corresponding to the locking holes 54. Multiple screening frames 52 are fixedly installed with screen plates 56 on their bottom surfaces. The aperture of the screen plates 56 gradually decreases from top to bottom. Multiple screening frames 52 are stacked and placed inside the placement opening 53. The locking posts 55 at the bottom of the multiple screening frames 52 are correspondingly locked into the locking holes 54 below. By installing the screening frames 52 one by one from bottom to top according to the aperture of their internal screen plates 56, and by placing the screening frames 52 into the placement frame 51 from the placement opening 53 and locking them into the locking holes 54 at the bottom for limiting, the installation of multiple screening frames 52 is completed. This allows for multi-level screening of materials from top to bottom, improving screening efficiency and ensuring screening accuracy.

[0024] Both sides of the placement frame 51 are fixedly connected with side rods 57 that are adapted to the height of the screening frame 52. The side rods 57 have limit holes 58 inside, and limit bolts 59 are movably installed inside the limit holes 58. One end of the limit bolts 59 passes through the limit holes 58 and extends to the top of the screening frame 52, which can further limit and fix the screening frame 52 to prevent the screening frame 52 from shaking or falling off during the screening process, thereby improving the stability and reliability of the screening. The limit bolts 59 can be manually tightened and disassembled to facilitate the quick disassembly and assembly of the screening frame 52, thereby improving the flexibility and practicality of the equipment.

[0025] The top of the placement frame 51 has a discharge port 510 to ensure that the material can smoothly enter the screening frame 52.

[0026] Please see Figure 3The drive assembly 4 includes a support frame 41 and a hinge block 42 fixedly installed on the top of the control box 1. A rocker arm 43 is rotatably connected to the inner side of the hinge block 42. The rocker arm 43 is fixedly connected to the top of the placement frame 51. A groove 44 is provided inside the rocker arm 43. A dual-axis motor 46 is fixedly installed inside the support frame 41. Turntables 45 are fixedly installed on the outside of the front and rear output shafts of the dual-axis motor 46. A cylinder located in the groove 44 is fixedly connected to the outside of the turntables 45. By activating the dual-axis motor 46, the front and rear shafts are driven. The turntable 45 rotates, and the cylinder on the outer edge of the turntable 45 moves in the slide 44. The circular motion of the cylinder in the slide 44 causes the swing rod 43 to swing around the hinge block 42, which in turn causes the screening assembly 5 to swing, thereby causing the internal material to swing. During the swing, the material is screened by the screening frame 52, and particles of different sizes are gradually separated. Since the swing of the swing rod 43 has a certain frequency and amplitude, it can effectively reduce the accumulation and blockage of material during the screening process and improve the screening efficiency.

[0027] Please see Figure 1 and Figure 5 The control box 1 includes a box body 11, a door 12 is hinged to the front of the box body 11, an observation window 13 is fixedly installed inside the door 12, a sound insulation pad 14 is fixedly glued inside the box body 11, and a sound insulation pad 15 is fixedly glued to the inside of the door 12. The sound insulation pad 14 and the sound insulation pad 15 can effectively absorb the noise generated by the screening machine during operation, reduce the noise interference to the surrounding environment, and the observation window 13 on the door 12 allows the user to observe the working status without opening the door 12, ensuring the smooth progress of the screening process, reducing the transmission of noise, and reducing the noise generated during operation.

[0028] Both sound insulation pad 14 and sound insulation pad 2 15 are made of sound insulation cotton. The observation window 13 uses sound insulation angled glass, which has a good sound insulation effect. While ensuring the clarity of observation, it can effectively block the transmission of noise and improve the noise reduction performance. The sound insulation pad 14 and sound insulation pad 2 15 made of sound insulation cotton have good sound absorption performance, which can effectively absorb the noise generated during operation, further reduce noise leakage, and provide a quieter working environment.

[0029] A pin 16 is fixedly installed on the side of the door 12. A locking rod 17 is rotatably connected to the outside of the pin 16. A locking block 18 that matches the locking rod 17 is fixedly connected to the outside of the box body 11. By utilizing the mutual adaptation between the locking rod 17 and the locking block 18, the door 12 can be securely locked to prevent it from being accidentally opened or shaken during operation. When it is necessary to open or close the door 12, the corresponding action can be completed relatively conveniently by operating the locking rod 17, which enhances the ease of use.

[0030] Working principle: When in use, the screening frame 52 is installed according to the hole diameter of its internal screen plate 56. First, the screening frame 52 with the smaller hole diameter of the screen plate 56 is placed into the inside of the placement frame 51 through the placement port 53, and the bottom locking post 55 is used to lock and limit the placement by corresponding to the locking hole 54 at the bottom of the placement frame 51. Similarly, according to the size of the hole diameter of the screen plate 56, the bottom locking hole 54 of the screening frame 52 is used to lock and limit the placement by corresponding to the locking hole 54 at the top of the screening frame 52 below. Then, the limiting bolt 59 is screwed into the limiting hole 58 on the side of the screening frame 52 corresponding to the highest position, so that the limiting bolt 59 is locked above the screening frame 52 for limiting. The material is added into the uppermost screening frame 52 through the discharge port 510.

[0031] Then, by closing the box door 12, the lever 17 is rotated along the pin 16 and locked outside the block 18 for limiting;

[0032] By starting the dual-axis motor 46, the turntables 45 on both the front and rear sides are rotated. The cylinders on the outer side of the turntables 45 slide in the grooves 44. The circular motion of the cylinders in the grooves 44 drives the swing rod 43 to swing along the hinge block 42. The swing rod 43 drives the sieving assembly 5 to swing, causing the internal materials to swing. The Chinese herbal medicine materials are screened through the progressively smaller sieve plates 56 into the corresponding screening frames 52, which facilitates multi-stage screening of materials, improves the flexibility of use, and reduces limitations. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
