Description

Technical Field

[0001] This utility model relates to the field of dried fruit processing technology, specifically to a vibrating screen machine for dried fruit processing. Background Technology

[0002] A vibrating screen, also known as a vibrating sieve or vibrating screen, is a mechanical device used for screening and grading solid materials. It separates particulate matter of different sizes by generating high-frequency vibrations and is widely used in food processing, mining, chemical and other industries.

[0003] Existing vibrating screens can be referenced from Chinese Utility Model Patent No. CN212190013U, which discloses a vibrating screen including a support, a vibrating screen body installed above the support, and a vibration component connected to the vibrating screen body. The side wall of the vibrating screen body is provided with a discharge port. The vibrating screen body is provided with a first filter screen and a second filter screen located below the first filter screen. Both the first and second filter screens are parallel to the bottom surface of the vibrating screen body. The filter holes of the second filter screen are smaller than those of the first filter screen. The side wall of the vibrating screen body is provided with a slag discharge port and a powder discharge port. This solution has the function of smooth discharge of seasonings in dried fruits and good screening effect.

[0004] The above-mentioned device has a good working effect. When using the device, the stir-fried dried fruit is placed inside the vibrating screen body. The vibration motor is started, causing the vibrating screen body to vibrate. The crumbs and seasonings in the dried fruit will fall into the second filter through the first filter screen. Since the filter holes of the second filter screen are smaller than those of the first filter screen, the crumbs can be separated, allowing the seasonings to fall to the bottom of the vibrating screen body.

[0005] However, the aforementioned device causes the entire vibrating screen to vibrate. During the vibration of the vibrating screen, the material inside the slag receiving box and powder receiving box may be spilled out along with the overall vibration of the vibrating screen. This not only leads to material waste, but may also pollute the working environment, increase the difficulty of cleaning, and affect production efficiency. Utility Model Content

The left side of the outer wall of the vibrating screen body 1 has two inclined discharge pipes 6 fixedly connected from top to bottom. The right ends of the two discharge pipes 6 are connected to the discharge port 101.

[0028] The vibrating screen body 1 serves as the main frame of the entire device, supporting all internal components and providing an enclosed space for screening dried fruits. It has an opening at the top for material input, and multiple discharge ports 101 on the left side for discharging materials of different particle sizes. Support legs 2 and a base 3 support the entire vibrating screen, ensuring its stable placement on the ground. The base 3 helps disperse the impact of vibration on the ground. Filter plates 4 and 5 are used for grading and screening dried fruits. Filter plate 4, located at the top, has a larger aperture to intercept larger particles; filter plate 5, located at the bottom, has a smaller aperture to further separate fine particles. Their tilted design, with the left side lower than the right, facilitates the material sliding to the left under gravity and discharging through the discharge ports 101. It is rotatably connected to the right side of the vibrating screen body 1, allowing for a certain degree of swaying to accommodate vibration. The discharge ports 101 are located on the left side of the vibrating screen body 1, evenly distributed from top to bottom, for discharging materials of different particle sizes separately. The discharge pipe 6 is installed on the left side of the outer wall of the vibrating screen body 1 and is connected to the discharge port 101. It is used to guide the material discharged from the first filter plate 4 and the second filter plate 5 to the collection container.

[0029] Furthermore, the vibrating screen body 1 has through slots 102 evenly spaced from top to bottom on the right side. The outer wall of the vibrating screen body 1 has mounting shells 14 fixedly connected from top to bottom on the right side. Horizontal threaded rods 15 are rotatably connected inside the two mounting shells 14. The front ends of the two horizontal threaded rods 15 are rotatably connected to the front side of the inner wall of the mounting shell 14, and the rear ends of the two horizontal threaded rods 15 extend to the rear side of the outer side of the mounting shell 14 and are rotatably connected thereto.

[0030] Mounting housing 14 is fixedly connected to the right side of the outer wall of the vibrating screen body 1, and is used to accommodate and support the horizontal threaded rod 15, providing structural support for the adjustment system.

[0031] Furthermore, two horizontal threaded rods 15 are threadedly connected to powder collecting pipes 16, and each powder collecting pipe 16 is fixedly connected to a slider 17 at its top. The top of the inner walls of the two mounting housings 14 are provided with sliding grooves, and the two sliders 17 are slidably connected to these grooves. This sliding connection between the sliders 17 and the grooves ensures the stability and straightness of the powder collecting pipes 16 during horizontal movement, avoiding unnecessary offset or shaking.

[0032] Furthermore, two powder collection pipes 16 are fixedly connected to a plurality of powder suction pipes 18 arranged at equal intervals on one side of the vibrating screen body 1. The plurality of powder suction pipes 18 extend into the interior of the vibrating screen body 1 and are slidably connected to the inner wall of the through groove 102. The plurality of powder suction pipes 18 are located on the lower right side of the first filter plate 4 and the second filter plate 5, respectively.

[0033] The suction pipe 18 extends into the body 1 of the vibrating screen and slides between it and the inner wall of the through groove 102. It is located below the right side of the first filter plate 4 and the second filter plate 5, and is used to directly suck up fine particles or powdery materials falling from the filter plates. Multiple suction pipes 18 are equidistantly arranged to ensure uniform material collection across the entire width. As the powder collection pipe 16 moves, the suction pipe 18 can also adjust its position synchronously to always maintain the optimal collection position.

[0034] Furthermore, the two powder collecting pipes 16 are respectively fixedly connected to the first elastic powder conveying pipe 21 and the second elastic powder conveying pipe 22 on the side away from the powder suction pipe 18. The first elastic powder conveying pipe 21 is located above the second elastic powder conveying pipe 22. The ends of the first elastic powder conveying pipe 21 and the second elastic powder conveying pipe 22 away from the powder collecting pipe 16 extend to the outside of the mounting shell 14 and are slidably connected thereto.

[0035] Furthermore, a powder collection box 23 is fixedly connected to the bottom of the first elastic powder conveying pipe 21 and the second elastic powder conveying pipe 22. A base 3 is fixedly connected to the bottom of the powder collection box 23. A negative pressure pump 25 is fixedly connected to the front side of the top of the base 3. A connecting pipe 24 is fixedly connected to the suction end of the negative pressure pump 25. The end of the connecting pipe 24 away from the negative pressure pump 25 is fixedly connected to the center of the front side of the powder collection box 23. A box door 26 is movably connected to the rear side of the powder collection box 23.

[0036] The first flexible powder conveying pipe 21 and the second flexible powder conveying pipe 22 will transfer the fine particles or powdery materials collected from the powder collecting pipe 16 to the powder collecting box 23 outside the mounting shell 14. The end away from the powder collecting pipe 16 extends to the outside of the mounting shell 14 and is slidably connected to it, allowing it to move synchronously with the rotation of the horizontal threaded rod 15, keeping the material conveying path unobstructed.

[0037] The powder collection box 23 is used to collect fine particles or powdery materials transported through the first elastic powder conveying pipe 21 and the second elastic powder conveying pipe 22. A base 3 is fixedly connected to the bottom to ensure stable placement. A door 26 is movably connected to the rear side for easy cleaning and removal of the collected materials. The negative pressure pump 25 generates negative pressure to help the suction pipe 18 more effectively suck up fine particles or powdery materials and transport them to the powder collection box 23 through the first elastic powder conveying pipe 21 and the second elastic powder conveying pipe 22. The connecting pipe 24 transmits the negative pressure generated by the negative pressure pump 25 to the powder collection box 23, helping to maintain the negative pressure state inside the powder collection box 23.

[0038] Furthermore, two horizontal threaded rods 15 are fixedly fitted with No. 3 sprockets 19 on the outer surface of the mounting shell 14, and a No. 3 chain 20 is meshed between the two No. 3 sprockets 19. A No. 2 sprocket 12 is also fixedly fitted on the surface of the upper horizontal threaded rod 15. A cam 7 is rotatably connected to the bottom center of the No. 1 filter plate 4 and the No. 2 filter plate 5. A No. 1 rotating rod 8 is fixedly connected to the inner wall of the two cams 7. The rear ends of the two No. 1 rotating rods 8 extend to the rear side of the vibrating screen body 1 and are rotatably connected thereto. A No. 2 sprocket 12 is fixedly fitted on the rear side surface of the lower No. 1 rotating rod 8 on the outer side of the vibrating screen body 1, and a No. 2 chain 13 is meshed between the two No. 2 sprockets 12.

[0039] Furthermore, two No. 1 rotating rods 8 are fixedly fitted with No. 1 sprockets 9 on the rear surface of the vibrating screen body 1. A No. 1 chain 10 is meshed between the two No. 1 sprockets 9. A power motor 11 is fixedly connected to the top rear side of the vibrating screen body 1. The output shaft of the power motor 11 is fixedly connected to one end of the No. 1 rotating rod 8 above. A controller 27 for controlling the entire device is fixedly connected to the front surface of the vibrating screen body 1.

[0040] After the power motor 11 starts, its output shaft drives the first rotating rod 8 above to rotate. Through the second sprocket 12 and the second chain 13, the power is transmitted to the first rotating rod 8, thus causing the two first rotating rods 8 to rotate synchronously. Since the first rotating rod 8 is connected to the cam 7, this will cause the two cams 7 to rotate synchronously, generating periodic vibrations, which helps the material to be evenly distributed on the filter plate.

[0041] After the power motor 11 starts, it drives the first rotating rod 8 to rotate. The first rotating rod 8 supports and rotates the cam 7, causing the cam 7 to vibrate periodically. This vibration is transmitted to the filter plates through the rotational connection at the bottom center of the first filter plate 4 and the second filter plate 5, helping the material to be evenly distributed on the filter plates. The two first rotating rods 8 rotate synchronously through the first sprocket 9 and the first chain 10, ensuring that the two cams 7 move in unison and provide a uniform vibration effect.

[0042] When the first rotating rod 8 rotates, it drives the second sprocket 12 to rotate. The second sprocket 12 drives the horizontal threaded rod 15 mentioned above to rotate through the second chain 13. The two horizontal threaded rods 15 rotate synchronously through the third sprocket 19 and the third chain 20. When the horizontal threaded rod 15 rotates, it moves laterally through the threaded connection of the powder collection pipe 16 and the powder suction pipe 18 to keep the material transmission path unobstructed. The negative pressure pump 25 generates negative pressure to help the powder suction pipe 18 more effectively suck up fine particles or powdery materials. The first elastic powder conveying pipe 21 and the second elastic powder conveying pipe 22 will transfer the fine particles or powdery materials collected from the powder collection pipe 16 to the powder collection box 23 outside the mounting shell 14. The box door 26 facilitates cleaning and removal of the collected materials.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
