The circular ring piece 212 is provided to be inclined toward the center of the fixing lever 211, and can prevent the collected chips from falling again.
When the sand bag 9 enters the hollow round steel 100, the electric telescopic rod 11 is controlled to squeeze the sand bag 9, when the grinding ring 201 contacts the inner wall of the hollow round steel 100, the sand bag 9 is stopped, at the moment, the grinding ring 201 does not wrap the electromagnetic ring 202, then the second motor 101 is controlled to drive the sand bag 9 to rotate, the sand bag 9 drives the grinding ring 201 and the electromagnetic ring 202 to rotate, the inner wall of the hollow round steel 100 is ground through the rotation of the plurality of grinding rings 201, rust and attached scraps of the inner wall are ground, and when the sand bag is ground, a power supply is connected with the electromagnetic ring 202 at the same time, so that the electromagnetic ring 202 generates magnetic force, iron components are mixed in the iron rust, the rust scraps under grinding are adsorbed on the surface through the magnetic force, and then the first push rod 102 is controlled to drive the grinding ring 201 to repeatedly move on the inner wall of the hollow round steel 100, so that the inner wall is ground thoroughly; after finishing polishing, because the interior of the sand bag 9 is also provided with the scrap impurities which are not adsorbed by magnetic force and the residual rust scraps, when the sand bag 9 is extruded, part of the gas in the sand bag flows to the through hole 10a of the extrusion plate 10 and then enters the air bag 213 through the air port 211a communicated with the through hole 10a, so that the air bag 213 can be expanded to be attached to the inner wall of the hollow round steel 100, then the air bag 213 is driven by the first push rod 102 to move, the scrap impurities in the sand bag are thoroughly scraped, when the scrap impurities are scraped, most scraps are accumulated on the air bag 213, the air bag 213 is extruded, part of scraps overflow and stay on the inner wall surface of the hollow round steel 100, and when the air bag 213 passes through, the overflowed scraps are extruded and crushed, so that the scraps in the hollow round steel 100 are more difficult to clean and are not cleaned, through the groove 213a, the accumulation of the scraps and impurities on the air bag 213 can be relieved, meanwhile, because the hollow round steel 100 is transversely placed on the placing block 8, most of the scraps and impurities in the hollow round steel are accumulated at the bottom of the inner wall of the hollow round steel 100, when the hollow round steel 100 rotates, the scraps accumulated at the bottom can be driven to move upwards through the baffle 214 arranged on the groove 213a, and when the scraps move upwards, the scraps fall downwards and then fall into the storage groove 211b, and in addition, the collected scraps can be prevented from falling again in the rotation through the circular ring piece 212 obliquely arranged towards the center of the fixing rod 211, the scraps accumulated at the bottom are dispersed and collected, so that when the scraps and impurities are scraped, part of scraps are prevented from accumulating and overflowing, the scraps and impurities stay in the hollow round steel 100, and finally, the scraps and impurities can be removed only by driving the air bag 213 to move out;
when the electromagnetic ring 202 adsorbs rust scraps, when scraps are adsorbed and covered on the surface of the electromagnetic ring 202, the adsorption force of the electromagnetic ring 202 is reduced, the subsequent scraping difficulty is further increased, meanwhile, as the electromagnetic ring 202 is easy to collide with the inner wall of the hollow round steel 100 when rotating, and damage to the electromagnetic ring 202 occurs, when the sand bag 9 is extruded to fill the hollow round steel 100, the length of the sand bag 9 is contracted, the contraction force is transmitted to all polishing systems through a straight rod fixedly connected with the extrusion plate 10, a convex ball on the straight rod drives a polishing ring 201 close to the extrusion plate 10 in each polishing system to move, and then the corresponding polishing rings 201 can be driven to move when the length of the sand bag 9 is contracted, so that the polishing rings 201 positioned at two sides of the electromagnetic ring 202 are mutually moved to wrap the electromagnetic ring 202, and the conditions of collision and damage do not occur when the hollow round steel 100 is filled; and after the electromagnetic ring 202 adsorbs a period of time, after the surface adsorbs enough rust fragments, stop electric current and electromagnetic ring 202 intercommunication simultaneously, stop the magnetic attraction, make the rust fragments of absorption break away from its surface, and fall into collecting vat 201a, simultaneously be equipped with scraper bar 203, because sand bag 9 is flexible material, grind ring 201 and electromagnetic ring 202 do not rigid coupling together, through the forward transmission of sand bag 9 and reversal, grind ring 201 and electromagnetic ring 202 rotational speed are different, and then can scrape the electromagnetic ring 202 surface through scraper bar 203, further clearance adsorbed rust fragments, and then collect in collecting vat 201a, and scraper bar 203 is in slope setting to the center of a circle of grind ring 201, because the rust that adsorbs has the large-scale piece rust piece and by tiny rust powder, along with rotating, the piece in collecting vat 201a of top can drop down, and then move around in the space that two grind rings 201 merge, the iron piece of large-scale piece can strike electromagnetic ring 202, damage electromagnetic ring 202, through the stopper of scraper bar 203, can prevent the large-scale piece 201a from falling down again in the collecting vat, and the scraper bar 201a can be prevented from shaking off, and the setting up in the collecting vat again, and the setting up in the place of scraper bar 201.
