Description

Technical Field

[0001] The utility model relates to the technical field of belt cleaners, in particular to a polyurethane scraper provided with a mounting structure. Background Art

[0002] Belt cleaner, also known as scraper, is mainly used at the head and tail of the belt conveyor. The belt cleaner is placed at the head of the belt conveyor. The cleaner is one of the main components of the belt conveyor. In order to prevent dust during material transportation and meet production process requirements, most of the conveyed materials need to maintain a certain moisture content. For example, the moisture content of coal conveyor belts in many power plants is about 12%, which will inevitably cause the moisture-containing materials to adhere to the belt. If they are not cleaned, they will continue to fall after colliding with the return roller during the operation of the belt.

[0003] Polyurethane scrapers are usually used on belt cleaners to scrape materials, but currently polyurethane scrapers usually do not have the function of height adjustment, which makes it impossible to scrape materials on the belt surface at different heights, reducing the scope of use of the polyurethane scraper and causing defects.

[0028] Furthermore, a connecting plate 27 is rotatably connected to the top of the threaded rod 26, and a second mounting bracket 28 is fixedly connected to the surface of the connecting plate 27. The second mounting bracket 28 is fixedly connected to the surface of the support frame 1. The height of the polyurethane scraper body 37 can be driven to be adjusted through the set threaded rod 26.

[0029] Furthermore, first mounting frames 21 are fixedly connected to both sides of the support frame 1 , and the first mounting frames 21 are symmetrically arranged on both sides of the support frame 1 . The stability of the support frame 1 can be ensured by the arrangement of the first mounting frames 21 .

[0030] Embodiment 2:

[0031] See also Figure 4 On the basis of the first embodiment, the cleaning mechanism 3 further comprises a fixing plate 32, the fixing plate 32 is threadedly connected to the surface of the threaded rod 26, both sides of the fixing plate 32 are slidably connected to support rods 31, the top of the support rod 31 is slidably connected to a connecting piece 34, the connecting piece 34 is fixedly connected to the top of the fixing plate 32, and the polyurethane scraper body 37 can be supported by the set support rod 31.

[0032] Furthermore, a spring 33 is sleeved on the surface of the support rod 31, and a fixing ring 35 is arranged at the bottom of the spring 33. The fixing ring 35 is fixedly connected to the surface of the support rod 31, and the fixing ring 35 is arranged on the top of the fixing plate 32. The spring 33 is constantly in a stretched or compressed state, which can leave a certain amount of activity space for the polyurethane scraper body 37, avoiding damage to the polyurethane scraper body 37, and playing a good protective role for the polyurethane scraper body 37.

[0033] Furthermore, a mounting part 36 is fixedly connected to the bottom of the support rod 31, and a polyurethane scraper body 37 is inserted into the mounting part 36. A threaded hole is opened between the polyurethane scraper body 37 and the mounting part 36, and an adjusting bolt is threadedly connected in the threaded hole.

When the threaded holes on the surface of the polyurethane scraper body 37 coincide with the threaded holes on the surface of the mounting member 36, the polyurethane scraper body 37 can be installed by threading the locking bolts into the interior of the polyurethane scraper body 37. The polyurethane scraper body 37 can also be disassembled. After the polyurethane scraper body 37 is installed, the support frame 1 is fixed to the belt side frame through the mounting holes. Then, the motors 22 on both sides are started at the same time. The motor 22 drives the threaded rod 26 on one side to rotate synchronously. Under the linkage effect formed by the pulley group 23, the threaded rods 26 on both sides can be driven to rotate synchronously. The pattern rod 26 rotates synchronously and drives the fixed rod 24 to rise and fall, thereby realizing the adjustment of the height of the polyurethane scraper body 37, ensuring contact with the belt surface, and being able to adapt to belts of different heights, thereby expanding the scope of use of the device. At this time, the polyurethane scraper body 37 can clean the residual materials on the belt surface. When the polyurethane scraper body 37 encounters hard materials, it will drive the support rod 31 to slide inside the connecting piece 34, and the spring 33 will be continuously in a stretched or compressed state, which can leave a certain amount of activity space for the polyurethane scraper body 37, thereby avoiding damage to the polyurethane scraper body 37 and providing good protection for the polyurethane scraper body 37.
