Description

Technical Field:

[0001] The utility model relates to a drum screen, specifically a self-cleaning drum screen, belonging to the technical field of drum screens. Background Technique:

[0002] In the process of ore mining, ore is blasted from the mine, transported to the bunker by an excavator and a transport vehicle, conveyed into a jaw crusher by a chain feeder for crushing, and the crushed ore is conveyed to a drum screen by a belt conveyor for primary classification. The fine material after primary classification is conveyed to a material pile by a belt conveyor. A drum screen is a device that classifies materials by using a rotating drum and a screen mesh. Ore particles roll in the drum and are sieved by the screen mesh, and are divided into different grades according to the particle size. However, the screen holes of the existing drum screens are easily blocked by materials.

[0003] It is known that the Chinese publicly authorized utility model (publication number: CN219816963U) discloses a self-cleaning drum screen, which solves the problem that the screen holes of the drum screen are easily blocked by small particle materials and need to be frequently cleaned manually by setting a rotating shaft, a screen body, a cleaning structure, a cleaning roller, and a brush sleeve; when the cleaning roller rotates, it drives the brush sleeve to rotate. Since the bristles on the surface of the brush sleeve contact the outer surface of the screen body, the particulate matter and wet materials stuck in the screen holes of the screen body can be cleaned, realizing the self-cleaning function;

[0004] It mainly cleans the materials stuck in the screen holes through the brush sleeve. Although it can achieve a certain cleaning effect, the bristles are prone to deformation after long-term use, and when the ore materials stuck in the screen holes are relatively firm, the cleaning effect is poor.

[0031] In this embodiment, specifically: the two lifting seats 23 are symmetrically and rotatably connected to the outer side wall of the rotating shaft 16. The guide rod 22 is slidably connected to the inside of the mounting frame 18. The threaded rod 20 is threadedly connected to the inside of the mounting frame 18. When the threaded rod 20 is rotated, since the threaded rod 20 is threadedly connected to the mounting frame 18, the threaded rod 20 drives the lifting seat 23 to move upward. The lifting seat 23 drives the rotating shaft 16, and the distance between the knocking wheel 17 and the screening cylinder 31 can be adjusted to meet different usage requirements.

[0032] In this embodiment, specifically: the driving motor 19 is installed on the front surface of one lifting seat 23. The rotating shaft 16 is driven by the driving motor 19. The rotating shaft 16 drives the knocking wheel 17. The knocking wheel 17 knocks on the screening cylinder 31, which can cause the materials stuck in the screening holes to vibrate and break away from the screening holes.

A support frame 24 is installed on one side of the installation frame 18. The installation frame 18 is fixedly connected to the upper surface of the other flow guiding cover 39 through the support frame 24. The position of the transmission shaft 13 can be limited through the fixed seats 14, and the position of the installation frame 18 can be limited through the support frame 24.

When the screening cylinder 31 rotates, the inserted teeth 12 are staggered and inserted into the sieve holes, and the materials stuck in the sieve holes can be cleaned.

[0039] Working principle or structural principle: During use, the drive motor 34 drives the drive rod 36 to rotate. The drive rod 36 drives the drive wheel 35 to rotate. The drive wheel 35 drives the screening cylinder 31 to rotate through the drive ring 33. The screening cylinder 31 rotates clockwise, and at this time, ore screening operations can be carried out. During the screening process, the drive ring 33 drives the gear ring 32 to rotate. The gear ring 32 drives the transmission gear 15 to rotate through the teeth. The transmission gear 15 drives the transmission shaft 13 to rotate. The transmission shaft 13 drives the turntable 11. The turntable 11 drives the inserted teeth 12. The turntable 11 rotates synchronously with the screening cylinder 31. The inserted teeth 12 are inserted into the sieve holes inside the screening cylinder 31, and thus the ore materials stuck in the sieve holes can be cleaned. The drive motor 19 drives the rotating shaft 16. The rotating shaft 16 drives the knocking wheel 17. The knocking wheel 17 knocks on the upper part of the screening cylinder 31. Through the two cleanings by the inserted teeth 12 and the knocking wheel 17, the materials in the screening holes can fall off.
