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.

[0024] Please see Figure 1-3 A vibrating screen for flour processing with adjustable vibration amplitude includes a housing 1, a support frame 2 fixedly connected to the bottom of the housing 1, a vibrating device 3 fixedly connected to the top of the housing 1, a screening device 4 fixedly connected to the top output end of the vibrating device 3, and a material receiving device 5 fixedly connected to one side of the inner wall of the housing 1.

[0025] Furthermore, the vibration device 3 includes a hydraulic cylinder 6, a support block 7, and a spring 8. The hydraulic cylinder 6 is fixedly connected to one end of the top of the housing 1, the support block 7 is fixedly connected to the top output end of the hydraulic cylinder 6, and the spring 8 is fixedly connected to the top of the support block 7.

[0026] Furthermore, the screening device 4 includes a vibrating screen 9, a coarse screen 10, a fine screen 11, a vibrating motor 12, and a second vibrating motor 13. The top output end of the spring 8 is fixedly connected to the vibrating screen 9. The coarse screen 10 is fixedly connected to one side of the inner wall of the vibrating screen 9. The fine screen 11 is fixedly connected to the bottom of the vibrating screen 9, and the coarse screen 10 and the fine screen 11 are parallel vertically. The vibrating motor 12 is fixedly connected to one side of the outer wall of the vibrating screen 9, and the second vibrating motor 13 is fixedly connected to the outer wall of the vibrating screen 9 away from the vibrating motor 12.

[0027] Furthermore, the receiving device 5 includes a slide rail 14 and a collection box 15. The slide rail 14 is fixedly connected to one side of the inner wall of the box body 1, and the collection box 15 is fixedly connected to the side of the slide rail 14 away from the box body 1.

[0028] Furthermore, a handle 16 is fixedly connected to the outer wall of one end of the collection box 15.

[0029] Furthermore, the bottom output end of the support frame 2 is made of rubber.

[0030] Furthermore, four vibration devices 3 are evenly arranged on the top of the housing 1.

[0031] Working Principle: First, the hydraulic cylinder 6 serves as the main power source, driving the support block 7 to move up and down through its telescopic movement. The spring 8 connected to the top of the support block 7 further amplifies this up-and-down movement effect and provides additional elastic cushioning, making the vibration more stable and adjustable. The vibration motor 12 and the second vibration motor 13 are respectively installed on both sides of the vibrating screen 9. They work together to provide horizontal vibration for the vibrating screen 9. Combined with the vertical vibration generated by the hydraulic cylinder 6 and the spring 8, a multi-dimensional sieving effect is formed. When the vibrating screen 9 starts to vibrate under the drive of the vibration device 3, the flour raw material placed on the vibrating screen 9 will be subjected to this vibration. The flour raw material first undergoes preliminary sieving through the coarse screen 10. Larger particles or impurities are trapped on the coarse screen 10, while smaller particles fall through the coarse screen 10 into the fine screen 11 below. On the fine screen 11, the flour is further sieved into finer particles, while removing even smaller impurities, ensuring the purity and particle size uniformity of the final product. After sieving... Flour particles are held at different positions on the coarse screen 10 and fine screen 11 according to their particle size, or eventually fall into the collection area below through the screen. The collection box 15 is installed on one side of the inner wall of the box body 1 via the slide rail 14, which makes it easy to slide out for flour collection or cleaning. The handle 16 on the collection box 15 provides a convenient grip point for easy operation. By adjusting the extension and retraction of the hydraulic cylinder 6, the vibration amplitude of the vibrating screen 9 can be changed, thereby adjusting the screening efficiency and accuracy. This adjustability allows the vibrating screen to adapt to different types and particle sizes of flour raw materials, improving the versatility and flexibility of the equipment. The bottom of the support frame 2 is made of rubber, which effectively reduces the impact and noise of the vibrating screen on the ground during operation, while increasing the stability and durability of the equipment. Four vibration devices 3 are evenly arranged on the top of the box body 1 to ensure the stability and uniformity of the vibrating screen 9 during vibration, further improving the screening effect.
