Description

Technical Field

[0001] This utility model relates to the field of screening devices, and in particular to a vibrating multi-stage screening device for highway aggregates. Background Technology

[0002] In the field of highway construction, aggregates are a core component of key building materials such as concrete and asphalt. The particle size classification accuracy of aggregates directly affects the strength and durability of engineering structures. Vibrating highway aggregate multi-stage screening devices, with their multi-stage screen stratification characteristics, can efficiently separate aggregates of different particle sizes and have become the core equipment in the aggregate processing stage.

[0003] During the vibrating screening process, aggregates are prone to generating a large amount of dust due to collisions, friction, and impacts from falling particles. This dust not only contains fine particles such as stone powder and sand, but may also be mixed with soil impurities adhering to the surface of the aggregates. The dust diffuses into the surrounding environment, which not only endangers the respiratory health of operators, but may also adhere to the surface of the equipment's transmission components, accelerating the wear of key components such as bearings and vibrating motors, and shortening the service life of the equipment.

[0004] To address these issues, a vibratory multi-stage screening device for highway aggregates is proposed. Utility Model Content

The vibrating screen is fixedly connected to the top of the base by a spring, and the top cover is fixedly connected to the top of the base by a connecting plate. The fixed sleeve 2 is connected to the top of the top cover. During the screening process, dust will enter the interior of the fixed sleeve 2 through the top cover.

[0035] The left side of the fixed sleeve 2 is connected to the transmission sleeve 3, and the top left side of the transmission sleeve 3 is connected to the fan 4, which is an axial flow fan. The transmission sleeve 3 is equipped with a filter cylinder 5. The front and back of the filter cylinder 5 are fixedly connected to a disc 6. The surface of the disc 6 is connected to a toothed cylinder 7. The toothed cylinder 7 is fixedly installed inside the transmission sleeve 3 through a bearing seat. The bottom right side of the transmission sleeve 3 is fixedly connected to a discharge sleeve 8. The bottom of the discharge sleeve 8 is connected to a guide sleeve 20. The bottom of the clamping plate 11 is in contact with the bottom of the inner wall of the transmission sleeve 3. By setting the guide sleeve 20, the dust can be concentrated and guided, and the dust can be accurately discharged into the external collection bucket. A motor 9 is fixedly connected to the bottom left side of the transmission sleeve 3. The output end of the motor 9 passes through the interior of the transmission sleeve 3 and is fixedly connected to a screw 10. A clamping plate 11 is threaded onto the right side of the screw 10. The right end of the clamping plate 11 passes through the interior of the discharge sleeve 8. A circular groove 25 is provided on the right side of the inner wall of the discharge sleeve 8. The right end of the screw 10 is slidably connected inside the circular groove 25. By setting the circular groove 25, the right end of the screw 10 can be supported, improving the stability of the screw 10 during rotation. L-shaped toothed plates 12 are fixedly connected to both the front and back of the clamping plate 11. The left side of the transmission sleeve 3 is connected to... A protective mesh cover 23 is bolted and installed on the surface of the fan 4 and the motor 9. The protective mesh cover 23 protects the surface of the fan 4 and the motor 9 and prevents foreign objects from colliding with the motor 9. The L-shaped toothed plate 12 meshes with the toothed cylinder 7. A positioning plate 24 is fixedly connected to the left side of the bottom of the transmission sleeve 3. The end of the positioning plate 24 away from the transmission sleeve 3 is fixedly connected to the surface of the vibrating screening device 1. The positioning plate 24 supports the transmission sleeve 3 and improves the stability of the transmission sleeve 3. An opening 13 is opened at the top right side of the filter cylinder 5.

[0036] Reference Figure 3-5The transmission sleeve 3 is internally equipped with a striking assembly, which includes a bevel gear 14. The bevel gear 14 is fixedly mounted on the left side of the inner wall of the transmission sleeve 3 via a bearing seat. A bevel gear 15 is fixedly connected to the surface of the screw 10, and the bevel gear 15 meshes with the bevel gear 14. A half gear 16 is fixedly connected to the top right side of the bevel gear 14, and a striking tooth plate 17 meshes with the surface of the half gear 16. The left end of the striking tooth plate 17 extends through to the left side of the transmission sleeve 3. Spring pieces 18 are fixedly connected to both the front and rear sides of the left side of the striking tooth plate 17. The left end of the spring piece 18 is fixedly connected to... Connected inside the transmission sleeve 3, through the coordinated use of structures such as the bevel gear 14, bevel gear 15, and half gear 16, the disc 6 can be struck when the filter cylinder 5 rotates. The vibration generated by the striking causes the dust clogging inside the filter cylinder 5 to fall down, increasing the discharge speed. The front and rear sides of the inner wall of the transmission sleeve 3 are provided with sliding grooves 19. The front and rear ends of the striking tooth plate 17 are slidably connected inside the sliding grooves 19. By setting the sliding grooves 19, the striking tooth plate 17 can be supported and limited, improving the stability of the striking tooth plate 17 when moving.

[0037] Reference Figure 4-6 The filter cylinder 5 is equipped with a fixing rod 21. The front and rear ends of the fixing rod 21 pass through the toothed cylinder 7 and are fixedly connected to the inside of the transmission sleeve 3. A concave scraper 22 is fixedly connected to the top of the fixing rod 21. The top of the concave scraper 22 contacts the inner wall of the filter cylinder 5. By setting the fixing rod 21 and the concave scraper 22, stubborn impurities adhering to the inside of the filter cylinder 5 can be scraped off, preventing impurities from clogging the filter cylinder 5.

[0038] Working principle: The user first starts the vibrating screen 1, and then the aggregate is fed into the vibrating screen 1 for screening through the external conveying equipment. During the screening process, dust will spread. Then, the blower 4 is started. The blower 4 draws the dust through the transmission sleeve 3 and the fixed sleeve 2. The filter cartridge 5 filters the air containing dust to prevent dust from spreading. When it is necessary to clean the filter cartridge 5, the motor 9 is started. The electric screw 10 of the motor 9 rotates. The screw 10 drives the L-shaped toothed plate 12 to move to the left through the clamping plate 11. The L-shaped toothed plate 12 drives the filter cartridge 7 and the disc 6 to move the filter cartridge 12 to the left. As the filter cartridge 5 rotates, the screw 10 drives the half gear 16 to rotate via the bevel gear 15 and bevel gear 14. The half gear 16 pushes the striking tooth plate 17 to move to the left through its teeth. The striking tooth plate 17 compresses the spring 18. When it reaches its maximum position, the half gear 16 disengages from the striking tooth plate 17. The spring 18 drives the striking tooth plate 17 to quickly reset and strike the disc 6, causing the disc 6 and the filter cartridge 5 to vibrate, which in turn causes the dust to fall off. When the opening 13 is aligned with the discharge sleeve 8, the dust is discharged through the discharge sleeve 8 and the guide sleeve 20, thus achieving the advantage of effective dust removal.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
