[0008] As a preferred embodiment of the above technical solution, the bottom end of the vibration box and the top end of the base are both fixedly connected to limit posts, and the outer surfaces of adjacent limit posts are fitted with the same support spring.

[0009] As a preferred embodiment of the above technical solution, the top of the vibration box is fixedly connected to a box cover, and an acrylic transparent plate is snapped into the middle of the box cover.

[0016] While the first shock absorber provides radial damping for the guide column, the second shock absorber provides axial damping between the guide column and the guide cylinder. Furthermore, through the linkage mechanism between the drive arm and the pressure sensor, the damping amplitude can be guaranteed while the second shock absorber is providing damping. If the amplitude is too large, the pressure sensor will touch the inner wall of the annular support cylinder, thereby controlling the overall shutdown of the equipment. This facilitates personnel maintenance and ensures the quality of vibration screening, guaranteeing the overall stability and reliability. Attached Figure Description

Figures 1-9 As shown, it includes a vibration box 1, a limiting plate 2 is fixedly connected to the front and rear side surfaces of the vibration box 1, an adjustment component 3 is rotatably connected to the inner and outer side surfaces of the limiting plate 2, a support plate 4 is fixedly connected between the inner opposite surfaces of the limiting plate 2, and a base 5 is slidably connected to the inner side surface of the limiting plate 2.

[0029] The adjustment assembly 3 includes a rotating block 301 rotatably connected to the base 5. An electric push rod 302 is fixedly connected to the upper end of the rotating block 301. A base plate 303 is fixedly connected to the output end of the electric push rod 302. A guide post 304 is fixedly connected to the upper middle part of the base plate 303. A mounting bracket 305 is fixedly connected to the outer surface of the guide post 304. A Y-shaped plate 306 is slidably connected to the inner surface of the mounting bracket 305. A first shock absorber 307 is fixedly connected to the side of the Y-shaped plate 306 away from the guide post 304. A roller frame 308 is fixedly connected to the other end of the first shock absorber 307. A sliding roller 309 is rotatably connected to the outer surface of the roller frame 308. A spring telescopic rod 310 is fixedly connected between adjacent Y-shaped plates 306. The inner side of the mounting bracket 305 is fixedly connected to... A guide rod 311 is attached, with its outer surface slidably connected to the inner surface of the Y-shaped plate 306. Adjacent Y-shaped plates 306 are fixedly connected via connecting posts. A threaded screw 312 is rotatably connected to the bottom inner surface of the mounting bracket 305. The threaded screw 312 is fixedly connected to the side of the mounting bracket 305 near the guide post 304. The output end of the drive motor 313 is fixedly connected to the end of the threaded screw 312 near the guide post 304. The outer surface of the threaded screw 312 is threadedly connected to the inner surface of the Y-shaped plate 306. A guide cylinder 314 is slidably connected to the outer surface of the sliding roller 309. A rotating component 315 is fixedly connected to the top of the guide cylinder 314. The inner surface of the rotating component 315 is connected to the vibrating... The outer surface of the moving box 1 is rotatably connected to the bottom end of the guide cylinder 314, and a connecting piece 316 is rotatably connected to the bottom end of the connecting piece 316. A second shock absorber 317 is fixedly connected to the bottom end of the connecting piece 316, and the other end of the second shock absorber 317 is fixedly connected to the other connecting pieces 316.

Several driving arms 319 are rotatably connected to the lower end of the guide cylinder 314 and the upper inner end of the annular support cylinder 318. The other end of each adjacent driving arm 319 is rotatably connected to the same moving arm 320. A pressure sensor 321 is fixedly connected to the end of the moving arm 320 away from the guide post 304. The sensor is connected to the Y-shaped plate 306 and the spring extension.

Furthermore, the first shock absorber 307 cancels and controls the vibration generated by the vibration motor 18, ensuring that the vibration does not affect the bottom parts and improving the overall service life. The degree of shock absorption by the first shock absorber 307 between the guide column 304 and the guide cylinder 314 can be adjusted via the drive motor 313 and the threaded screw 312, thus adjusting the vibration amplitude of the vibration box 1. Simultaneously, adjusting the length of the electric push rod 302 changes the tilt angle of the vibration box 1, facilitating adjustment of vibration time and angle. While the first shock absorber 307 provides radial shock absorption to the guide column 304…The second shock absorber 317 provides axial vibration damping between the guide column 304 and the guide cylinder 314. Through the linkage mechanism between the drive arm 319 and the pressure sensor 321, the damping amplitude is ensured while the second shock absorber 317 is damping. If the amplitude is too large, the pressure sensor 321 will touch the inner wall of the annular support cylinder 318, thereby controlling the overall shutdown of the equipment. This facilitates personnel maintenance and ensures the quality of vibration screening, guaranteeing overall stability and reliability.

[0030] like Figures 1-9 As shown, limit posts 6 are fixedly connected to the bottom of the vibration box 1 and the top of the base 5. The outer surfaces of adjacent limit posts 6 are fitted with the same support spring 7. A box cover 8 is fixedly connected to the top of the vibration box 1. An acrylic transparent plate 9 is snapped into the middle of the box cover 8 to facilitate direct observation of the inside of the vibration box 1. Several mounting seats 10 are fixedly connected to the upper end of the vibration box 1. A rotating arm 11 and a driven arm 12 are rotatably connected to the inner surface of the upper end of the mounting seat 10. The inner surface of the rotating arm 11 is rotatably connected to the outer surface of the driven arm 12. A bolt is fixedly connected to the inner side of the rotating arm 11. A flexible abutment block 14 is fixedly connected to the outer surface of the bottom end of the fixed rod 13. The outer surface of the flexible abutment block 14 abuts against the upper end of the acrylic transparent plate 9, which facilitates the installation and disassembly of the acrylic transparent plate 9 and improves the overall reliability and functionality. A feed port 15 is opened on the upper right side of the box cover 8. A discharge port 16 is set on the left end of the vibration box 1. A drop port 17 is opened on the bottom left side of the vibration box 1. A vibration motor 18 is fixedly connected to the outer surface of the limiting plate 2. A screen 19 is fixedly connected to the middle of the inner side of the vibration box 1, which can screen polymer materials that do not meet the requirements.

[0031] like Figures 1-9 As shown, casters 20 are evenly fixedly connected to the bottom of the base 5 to facilitate the overall movement of the device. A waste bin 21 is snapped onto the upper left side of the base 5. The waste bin 21 is located directly below the discharge port 17. A collection box 22 is set below the outlet of the discharge port 16. Handles 23 are fixedly connected to the front and rear surfaces of the collection box 22. A movable wheel 24 is rotatably connected to the inner surface of the bottom of the collection box 22 to facilitate the discharge of the whole and improve the efficiency of processing and screening. The center lines of the guide cylinder 314, guide column 304 and annular support cylinder 318 are arranged coaxially. The bottom end of the annular support cylinder 318 abuts against the upper end of the base plate 303, which can improve the stability of the whole during operation.

[0032] Working principle: During use, raw materials are fed in through the feed inlet 15, and the vibration motor 18 is started. The vibration motor 18 drives the entire vibrating box 1 to vibrate. The raw materials are screened through the screen 19 inside the vibrating box 1. The qualified raw materials are sent into the limiting plate 2 through the discharge outlet 16, and the unqualified raw materials enter the waste bin 21 through the discharge outlet 17. During vibration, the Y-shaped plate 306 and the spring telescopic rod 310 ensure that the spring telescopic rod 310 moves synchronously, thereby ensuring that the force between the guide column 304 and the guide cylinder 314 is uniform. Furthermore, the first shock absorber... 307 can cancel and control the vibration generated by the vibration motor 18, ensuring that the vibration will not affect the bottom parts and improve the overall service life. The degree of vibration damping between the guide column 304 and the guide cylinder 314 can be adjusted by the drive motor 313 and the threaded screw 312, thereby adjusting the vibration amplitude of the vibration box 1. At the same time, by adjusting the length of the electric push rod 302, the tilt angle of the vibration box 1 can be changed, which makes it easy to adjust the vibration time and vibration angle. The left and right electric push rods 302 are staggered up and down. It can repeatedly vibrate and screen internal materials, control screening time and relative screen angle, improve screening functionality, and facilitate overall material discharge to avoid residue affecting screening quality. While the first shock absorber 307 provides radial vibration damping for the guide column 304, the second shock absorber 317 provides axial vibration damping between the guide column 304 and the guide cylinder 314. Through the linkage mechanism between the drive arm 319 and the pressure sensor 321, the damping amplitude can be guaranteed while the second shock absorber 317 is damping. If the amplitude is too large, the pressure sensor 321 will touch the inner wall of the annular support cylinder 318, thereby controlling the overall shutdown of the equipment, facilitating personnel maintenance and ensuring the quality of vibration screening, thus guaranteeing overall stability and reliability.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
