Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically a primary polyurethane alloy cleaner. Background Technology

[0002] Conveyor belts are rubber and fiber / metal composite products, or plastic and fabric composite products, used in belt conveyors to carry and transport materials. Conveyor belts are widely used in industries such as cement, coking, metallurgy, chemical, and steel for short-distance and small-volume conveying applications. During material transport, materials tend to adhere to the surface of existing conveyor belts. Cleaning these belts is mostly done manually, with workers holding a scraper and applying it at an angle to the belt surface. The movement of the belt then scrapes away the material. However, this method is time-consuming and labor-intensive, and when encountering hard materials, forcibly scraping them off can damage the conveyor belt surface. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a primary polyurethane alloy cleaner, which solves the problem that existing conveyor belts are prone to material adhesion during material transport. Most conveyor belt cleaning methods involve manual removal, where workers hold a scraper and apply it at an angle to the conveyor belt surface, using the belt's movement to remove the material. However, this method is time-consuming and labor-intensive, and when encountering hard-adhered materials, the forced scraping can easily damage the conveyor belt surface.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a primary polyurethane alloy cleaner, comprising a main beam and a pair of side plates.

A limiting assembly is provided on the wall of the connecting plate away from the sub-beams. The limiting assembly is hinged to the swing assembly.

[0006] Preferably, the swing assembly includes a swing shaft fixing plate, which is fixedly installed on the wall surface of the side plate away from the sub-beam. A swing shaft is provided between the swing shaft fixing plate and the side plate. A limiting part is provided between the swing shaft, the swing shaft fixing plate, and the side plate. An adjusting rod is inserted into the swing shaft. The rear end of the adjusting rod is hinged to the limiting assembly. A compression spring fixing block is installed at the front end of the adjusting rod. A compression spring is installed between the compression spring fixing block and the swing shaft. The compression spring is fitted onto the adjusting rod.

[0007] Preferably, the front end of the adjusting rod has an external thread, and an adjusting nut is screwed onto the external thread. The adjusting nut is located on one side of the compression spring fixing block.

[0008] Preferably, the limiting part includes a limiting plate, on which a cylindrical shaft block is fixedly installed.

[0011] Beneficial effects

[0012] This invention provides a primary polyurethane alloy cleaner that solves the problem of material easily adhering to the surface of conveyor belts during material transport. Currently, most conveyor belt cleaning methods involve manual removal, where workers hold a scraper and apply it at an angle to the conveyor belt surface, using the belt's movement to remove the material. However, this method is time-consuming and labor-intensive, and when encountering hard materials, the forced scraping can easily damage the conveyor belt surface. This invention addresses this issue by using a wear-resistant elastic polyurethane block to deform and push the hard alloy scraper head when it comes into contact with hard material. This allows the scraper head to pass over the hard material, preventing damage to the conveyor belt surface. During the swinging process, the main beam drives the secondary beam to rotate, which in turn drives the limiting component to rotate. The limiting component then drives the swinging component, causing the fixed main beam to swing all the hard alloy scraper heads, further preventing damage to the conveyor belt surface.

A swing shaft 13 is provided between the swing shaft 13 fixing plate 12 and the side plate 2. A limiting part is provided between the swing shaft 13, the swing shaft 13 fixing plate 12, and the side plate 2. An adjusting rod 14 is inserted on the swing shaft 13. The rear end of the adjusting rod 14 is hinged to the limiting assembly. A compression spring fixing block 15 is installed at the front end of the adjusting rod 14. A compression spring 16 is installed between the compression spring fixing block 15 and the swing shaft 13. The compression spring 16 is fitted onto the adjusting rod 14.

[0020] In this embodiment, the front end of the adjusting rod 14 is provided with an external thread, and an adjusting nut 17 is screwed onto the external thread. The adjusting nut 17 is located on one side of the compression spring fixing block 15.

[0021] In this embodiment, the limiting part includes a limiting plate 18, on which a cylindrical shaft block 19 is fixedly installed. A through hole is provided on the limiting plate 18 above the cylindrical shaft block. Threaded grooves are provided on the fixing plate 12 and side plate 2 of the swing shaft 13.

[0024] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0025] Example: As shown in the accompanying drawings, during use, the device is fixedly installed on the mounting surface by the base fixing plate 6. Rotating the adjusting nut 17 pushes the compression spring fixing block 15 along the external thread path, causing the compression spring fixing block 15 to push the compression spring 16, compressing the compression spring 16's stroke. This brings the carbide cutter head 4 into contact with the end surface of the transmission belt. When the carbide cutter head 4 contacts the hard material, the hard material pushes the carbide cutter head 4. Because the wear-resistant elastic polyurethane block 3 is made of elastic material, the carbide cutter head 4 swings, preventing the hard material from being pushed away. When the carbide cutter head 4 damages the surface of the transmission belt, the wear-resistant elastic polyurethane block 3 returns to its original shape after the hard material passes over the carbide cutter head 4, thereby causing the carbide cutter head 4 to reset. During this process, when the carbide cutter head 4 comes into contact with the hard material, the main beam 1 will drive the secondary beam 5 to rotate under the action of the wear-resistant sleeve 8, thereby causing the secondary beam 5 to drive the ring body 22 to rotate. The ring body 22 pulls the adjusting rod 14, causing the adjusting rod 14 to push the compression spring fixing block 15 and squeeze the compression spring 16, thereby allowing the carbide cutter head 4 to rotate as a whole, making it easier for the carbide cutter head 4 to pass over the hard material.
