Abstract
Description
Technical Field
[0001] This utility model relates to the field of belt conveyor technology, and in particular to a conveyor head cleaner. Background Technology
[0002] In industrial production, belt conveyors are widely used in mining, metallurgy, chemical, and building materials industries as core equipment for material transfer. However, during the unloading process at the head of the conveyor belt, materials tend to stick to or accumulate on the surface of the conveyor belt, which not only leads to material waste and pollution of the working environment, but may also cause conveyor belt misalignment, wear, or even tearing due to material residue, seriously affecting the operating efficiency and service life of the equipment. Therefore, it is now common practice to equip belt conveyors with cleaners for cleaning.
[0003] In existing technologies, head sweepers often use scrapers and brushes to periodically scrape the surface of the conveyor belt. However, traditional cleaning methods have many limitations when dealing with wet materials: when the conveyed material becomes more viscous due to high moisture content, or when it is in close contact with the conveyor belt in a humid environment, this wet material continuously accumulates and compacts on the conveyor belt, forming a dense block structure. The brush bristles, due to their flexible nature, cannot generate sufficient pressure, and the scraper is also limited by its fixed angle and material hardness, making it unable to push effectively. As a result, the cleaning operation can only remove surface floating material, while deeply adhered material remains. Utility Model Content
[0004] This invention proposes a conveyor head cleaner to solve the problem that existing traditional head cleaners have difficulty removing adhering materials when facing hardened, wet materials.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a conveyor head cleaner, comprising a rotating shaft, with brush bristles and scraping components mounted on the outside of the rotating shaft, the brush bristles and scraping components being arranged in a circular array and alternating, and further comprising:
[0006] The system includes a linkage component and an upper lifting component. The upper lifting component is located within the area enclosed by the conveyor belt. The linkage component is connected between the rotating shaft and the upper lifting component. When the rotating shaft rotates, the linkage component synchronously drives the upper lifting component to periodically lift the conveyor belt.
[0007] Preferably, the top assembly includes a support plate and a plurality of top rods mounted on the upper surface of the support plate along the length direction, wherein the top of the top rods is fixed with a round head.
[0008] Preferably, the plurality of top rods are arranged in an S-shape on the upper surface of the support plate.
[0009] Preferably, the linkage component includes a disc fixed to the end of the rotating shaft, an eccentric rod fixed to the outer wall of the disc, a connecting strip hinged to the eccentric rod, and a mounting plate connecting the bottom end of the connecting strip and the end of the support plate.
[0010] Preferably, the cleaning components are arranged in a circular array of three rows, with the three rows of cleaning components staggered in the circumferential direction.
[0011] Preferably, the cleaning component includes a connecting plate and a scraper. The connecting plate is fixed on a rotating shaft and has a groove. The scraper is retractably disposed in the groove, and a return spring is connected between the inner end of the scraper and the inside of the groove.
[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0013] (1) By setting up the linkage component and the top component, the cleaning effect is further improved. When the rotating shaft rotates, the linkage component drives the top component to periodically push the conveyor belt. The multiple top rods of the top component are distributed in a shape on the upper surface of the pallet, so that the top rods generate staggered upward force in the vertical direction, so that the head of the conveyor belt presents a staggered upward deformation shape, making the material easier to form a loose state, which is more conducive to subsequent cleaning.
[0014] (2) The retractable scraper can conform to the real-time shape changes of the conveyor belt, maintaining the scraping force on the material on the conveyor belt while protecting the surface of the conveyor belt and the scraper itself to the greatest extent, avoiding damage to the scraper and the conveyor belt due to excessive squeezing.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0025] like Figures 1-4 As shown, a conveyor head cleaner includes a rotating shaft 1. The end of the rotating shaft 1 can be rotated by installing a drive motor or by connecting it to the drive shaft of the belt conveyor through a gear connector. Brushes 2 and scrapers 3 are installed on the outside of the rotating shaft 1. The brushes 2 are made of a special material that is elastic and wear-resistant. The brushes 2 and scrapers 3 are arranged in a circular array and are distributed alternately. The scrapers 3 are arranged in a circular array with three rows. Each row has multiple scrapers 3. Each scraper 3 is retractable. The three rows of scrapers 3 are staggered in the circumferential direction to form staggered coverage, thereby reducing the thoroughness of scraping at the feeding end of the conveyor belt.
[0026] Among them, see Figure 4 As shown, the cleaning scraper 3 includes a connecting plate 31 and a scraper 32. The connecting plate 31 is fixed on the rotating shaft 1, and a groove 33 is provided on the connecting plate 31. The scraper 32 is telescopically positioned inside the groove 33. A return spring 34 is connected between the inner end of the scraper 32 and the inside of the groove 33. The scraper 32 extends and retracts due to the elasticity of the return spring 34. In use, the rotating shaft 1 rotates, causing the brush bristles 2 and the cleaning scraper 3 to rotate synchronously. The brush bristles 2 can loosen the material at the feeding end of the conveyor belt, and then the material is removed by the cleaning scraper. 3. The material loosened by brushing is scraped downwards. The cutting edge of the scraper 3 is treated (tungsten carbide coating or other) to ensure sufficient sharpness to scrape off the material smoothly, while also possessing good strength and durability to ensure that it will not easily wear and deform during long-term use. Through the reciprocating motion of the scraper 3, the material loosened by brushing is completely scraped off the conveyor belt, achieving a fast and clean unloading effect. This greatly reduces the accumulation and adhesion of material on the conveyor belt, ensuring the efficient and stable operation of the conveyor belt.
[0027] It should be noted that: preferably, the rotation direction of the rotating shaft 1 is consistent with the conveying direction of the belt conveyor, and the rotation speed of the rotating shaft 1 must be greater than the conveying speed of the belt conveyor in order to achieve cleaning in the same direction.
[0028] In addition, to ensure the stability of the sweeper installation, a support structure (not shown) is required for installation. The support structure only needs to ensure the stability of the sweeper after installation and ensure the normal operation of the sweeper and the conveyor (e.g., a connecting rod can be installed at the end of the rotating shaft 1, and a vertical support rod can be installed at the outer end of the connecting rod through a bearing). The specific structure will not be described in detail here.
[0029] See Figures 1-3 As shown, the conveyor head cleaner also includes a linkage component 4 and an upper lifting component 5. The upper lifting component 5 is set in the area enclosed by the conveyor belt. The linkage component 4 is connected between the rotating shaft 1 and the upper lifting component 5. When the rotating shaft 1 rotates, the linkage component 4 synchronously drives the upper lifting component 5 to periodically lift the conveyor belt.
[0030] Among them, see Figure 1 and Figure 3 As shown, the upper top assembly 5 includes a support plate 51 and a plurality of top rods 52 installed along the length direction on the upper surface of the support plate 51, with a round head 521 fixed at the top end of the top rod 52.
[0031] See Figure 1 As shown, multiple push rods 52 are distributed in an S-shape on the upper surface of the support plate 51. The S-shape distribution allows the push rods 52 to generate staggered upward pushing forces in the vertical direction, resulting in different positions of the conveyor belt head exhibiting a staggered upward convex deformation shape. When the conveyor belt carrying the material runs to this area, the material will be pulled, squeezed, and displaced as the conveyor belt deforms. For example, the material located at the convex crest will be stretched upward due to the upward pushing force, while the material at the adjacent trough will be dragged downward due to the concavity of the conveyor belt. This alternating dynamic force causes the originally compact material structure to be continuously pulled and separated, forming a loose material state, which is conducive to subsequent cleaning.
[0032] The linkage assembly 4 includes a disc 41 fixed to the end of the rotating shaft 1. An eccentric rod 42 is fixed to the outer wall of the disc 41. A connecting strip 43 is hinged to the eccentric rod 42. A mounting plate 44 is connected between the bottom end of the connecting strip 43 and the end of the support plate 51.
[0033] Based on the above, combined Figure 2As shown, 'a' represents the conveyor belt. In actual use, the continuous rotation of the rotating shaft 1 drives the brush 2 and the scraper 3 to rotate continuously. Simultaneously, during one revolution of the rotating shaft 1, the eccentric rod 42 and connecting bar 43 on the disc 41 move, which in turn drives the push rod 52 on the pallet 51 to push the feeding end of the conveyor belt once. The material is loosened by the push of the push rod 52, and together with the brush 2 and the scraper 3, the head of the conveyor can be effectively cleaned to ensure normal feeding.
[0034] In order to cope with the arching of the conveyor belt due to the upward push of the top rod 52, a telescopic scraper 32 is set to deal with the arched part. This adaptive telescopic design allows the scraper 32 to conform to the real-time shape change of the conveyor belt, which not only maintains the scraping force on the material on the conveyor belt, but also protects the surface of the conveyor belt and the scraper 32 itself to the greatest extent, avoiding excessive compression and damage to the scraper 32 and the conveyor belt.
[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
