Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0023] see Figure 1-Figure 2 , a scraper for reducing friction damage, comprising a drum 1, a magnetic part 2 is fixedly installed inside the drum 1, the magnetic parts 2 are arranged in alternating magnetic poles, a scraper seat 3 is fixedly installed at the lower position of the drum 1, and the scraper seat 3 The tip of the knife is in contact with the surface of the drum 1. A moving chamber 4 is opened inside the scraper seat 3. A piston seat 5 is slidably...

The invention relates to the technical field of mechanical cleaning, and discloses a friction damage reducing scraper which comprises a roller, a magnetic part is fixedly mounted in the roller, magnetic poles of the magnetic part are alternately arranged, a scraper seat is fixedly mounted below the roller, and a scraper tip of the scraper seat is in contact with the surface of the roller. A moving cavity is formed in the scraper base, and a piston base is movably installed in a cavity body of the moving cavity. Through the arrangement of the material bearing plate and the piston seat, when the piston seat moves rightwards, negative pressure is generated in the air cavity, then the material bearing plate deforms rightwards to be of a concave surface structure, after gas in the external environment enters the air cavity, the negative pressure in the air cavity disappears, the material bearing plate rebounds, and then materials adhering to the surface of the material bearing plate are bounced off; sticky materials are prevented from being gradually accumulated on the surface of the material bearing plate, so that the subsequently scraped sticky materials enter the contact position of the scraper seat and the roller, the friction force between the scraper seat and the roller is increased, and the abrasion of the scraper seat is increased.
Description
technical field [0001] The invention relates to the technical field of mechanical cleaning, in particular to a scraper for reducing frictional damage. Background technique [0002] In the existing crushing process, the crushing drum is usually used to squeeze the material, and then the material is crushed. Due to the great extrusion force of the material and the diversity of the crushed material, some materials will adhere to the surface of the drum. , At this time, it is necessary to use a scraper to scrape off the above-mentioned sticky material, so as to avoid the influence of the sticky material on the subsequent crushing operation. [0003] When some existing scrapers are in use, the scraper is fixed at the position below the roller, and the blade tip of the scraper is in contact with the surface of the roller, and then, through the continuous rotation of the roller, the sticky material on the surface is in contact with the scraper, and then It is scraped off by the sc...
