[0002] The material will adhere to the conveyer belt during the conveying process, and the existing technology uses a sweeper to clean the adhered material in real time, more specifically, the sweeper uses a polyurethane scraper to scrape the material to realize the cleaning function. The polyurethane scraper is in line contact with the conveyer belt, and during the scraping operation, the polyurethane scraper will be subjected to high-frequency local impact due to local stubborn adhesion and conveyer belt jumping. The local impact directly acts on the polyurethane scraper, which can easily cause the polyurethane scraper to be damaged. After the damage, the whole scraper needs to be replaced, which increases the maintenance cost, and the scraping effect of the above-mentioned line contact is not ideal. Therefore, the applicant has proposed a utility model patent with the publication number "CN210418201U" and the name "omnidirectional sweeper for conveyer belt", which uses multiple comb type scrapers to reduce the impact of local impact on the whole scraper, and uses approximate point contact to improve the cleaning force of stubborn adhesion on the conveyer belt and improve the cleaning effect. However, the scraper in the sweeper is rigidly fixed and still affected by the impact of conveyer belt jumping and local stubborn adhesion. The contact force between the scrapers and the conveyer belt is not stable, which still cannot achieve the ideal overall cleaning effect, and the wear difference between the scrapers is large, and the frequency of replacing the scrapers is high. Therefore, the sweeper needs to be further improved. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0019] The utility model is further illustrated below in combination with the drawings and examples. In the following detailed description, certain exemplary embodiments of the utility model are described by way of illustration only. It is needless to say that those skilled in the art can realize that the described embodiments can be modified in various ways without departing from the spirit and scope of the utility model. Therefore, the drawings and description are essentially illustrative, and are not used to limit the protection scope of the claims.

[0020] As Figures 1 to 5 As shown in the drawings, the comb-shaped flexible polyurethane sweeper comprises a sweeper carrier 1 for mounting on a conveyor frame, the structure of which can be set as required, which is not limited here. The sweeper carrier 1 comprises at least a mounting shaft for mounting the relevant cleaning structure.

[0021] A plurality of scraper seats 2 are arranged and mounted on the sweeper carrier 1, and the scraper seats 2 are mounting carriers of the sweeping scraper 5. Preferably, the sweeper carrier 1 is provided with a through T-shaped mounting groove 21, and each of the scraper seats 2 is fixedly provided with a T-shaped mounting body 22 for being fitted in the T-shaped mounting groove 21, and the two ends of the T-shaped mounting groove 21 are respectively fixedly provided with a scraper seat stopper 23. By fitting the T-shaped mounting body 22 in the T-shaped mounting groove 21, the installation operation is simplified, and after the two ends of the T-shaped mounting groove 21 are limited by the scraper seat stopper 23, the stability of the installation of the scraper seat 2 can be ensured; on the contrary, when the scraper seat 2 and the structure thereon are deformed or damaged, the corresponding T-shaped mounting body 22 can be fitted out of the T-shaped mounting groove 21 by dismounting the scraper seat stopper 23, so that the maintenance and replacement operation can be realized, and the maintenance and replacement are convenient. When specifically set, the sweeper carrier 1, more correctly, the T-shaped mounting groove 21 is formed on the mounting shaft by using two oppositely fixed F-shaped profiles.

[0022] Each of the scraper seats 2 is respectively provided with a scraper arm 3 arranged in a pitching swing manner, and an elastic pressure bearing structure 4 is arranged between the scraper arm 3 and the corresponding scraper seat 2; each of the scraper arms 3 is respectively fixedly provided with a cleaning scraper 5, and a scraper mounting structure 6 is arranged between the cleaning scraper 5 and the corresponding scraper arm 3; the elastic pressure bearing structure 4 is used to make the corresponding cleaning scraper 5 elastically abut on the conveying belt.

[0023] The plurality of cleaning scrapers 5 in the embodiment respectively form elastic contact with the conveying belt through the elastic pressure bearing structure 4. When the conveying belt jumps, the elasticity still enables the cleaning scrapers 5 to stably contact the conveying belt. Even if there is a local stubborn adhesion impact, only the cleaning scraper 5 of the local stubborn adhesion is impacted, and other cleaning scrapers 5 are not impacted. In the case that the local stubborn adhesion will raise the corresponding cleaning scraper 5 to a certain height, other cleaning scrapers 5 still maintain stable contact force under the action of the respective elastic pressure bearing structure 4, so that the material at the corresponding position of the conveying belt will not be missed, and the overall cleaning effect is good. In the case that all the cleaning scrapers 5 always maintain stable contact force for cleaning, the wear difference between the cleaning scrapers 5 will be reduced, thereby facilitating the reduction of maintenance and replacement frequency.

[0024] The elastic pressure bearing structure 4 includes two swing mounting ear plates 41 fixedly arranged on the scraper seat 2, two swing mounting holes are arranged on the two swing mounting ear plates 41 in a corresponding manner, and a swing mounting bolt 42 is fixedly and penetratingly arranged between the two swing mounting holes. Of course, the fixed and penetrating arrangement is achieved by using a tightening nut after penetrating arrangement, which is easily obtained by combining conventional technical means, and will not be described here. The elastic pressure bearing outer ring 43 is fixedly arranged on the scraper arm 3 and located between the two swing mounting ear plates 41. The elastic pressure bearing inner ring 44 is fixedly arranged on the swing mounting bolt 42. The elastic pressure bearing layer 45 is fixedly connected between the elastic pressure bearing outer ring 43 and the elastic pressure bearing inner ring 44. When the elastic pressure bearing outer ring 43 rotates relative to the elastic pressure bearing inner ring 44, the elastic pressure bearing layer 45 provides elastic force by elastic deformation.

[0025] Therefore, when the swing mounting bolt 42 is fixed during installation, the cleaning scraper 5 has an interference amount in contact with the conveying belt. After the whole embodiment is installed on the conveyor frame, the conveying belt reversely presses the cleaning scraper 5. At this time, the elastic pressure bearing outer ring 43 rotates relative to the elastic pressure bearing inner ring 44 to a certain extent, the elastic pressure bearing layer 45 elastically deforms, and provides elastic force for the cleaning scraper 5 to elastically abut on the conveying belt. When the elastic abutting force of the cleaning scraper 5 is not suitable, the swing mounting bolt 42 is loosened, the swing mounting bolt 42 is rotated to a suitable elastic abutting force, and then is fixed again, so that the convenience of adjusting the elastic abutting force can be realized.

[0026] The swing mounting bolt 42 is connected with the elastic pressure inner ring 44 by screw thread, and when the length of the elastic pressure inner ring 44 is less than the distance between the two swing mounting lugs 41, a gasket is added on the swing mounting bolt 42 between the two swing mounting lugs 41 to limit the axial position of the elastic pressure inner ring 44 on the swing mounting bolt 42, so as to avoid axial displacement of the elastic pressure inner ring 44 due to screw thread connection during use, and ensure reliable elastic force.

[0027] The scraper mounting structure 6 comprises a scraper mounting stud 31 fixedly arranged on the scraper arm 3, the cleaning scraper 5 is sleeved on the scraper mounting stud 31, and a scraper position fixing nut 61 is arranged on the scraper mounting stud 31 at both sides of the cleaning scraper 5. In this way, the cleaning scraper 5 is fixedly mounted, and the cleaning scraper 5 is convenient to disassemble and replace.

[0028] Preferably, a scraper mounting fixing plate 62 is sleeved on the scraper mounting stud 31 at the side of the cleaning scraper 5, a fixing plate fixing nut 63 is arranged on the scraper mounting stud 31 at both sides of the scraper mounting fixing plate 62, and a scraper supporting plate 64 is fixedly arranged on the scraper mounting fixing plate 62 and located at the bottom of the cleaning scraper 5. Through the arrangement of the scraper mounting fixing plate 62 and the scraper supporting plate 64, the fixed posture of the cleaning scraper 5 can be further stabilized, and the cleaning scraper 5 can reliably scrape materials.

[0029] Preferably, the scraper mounting fixing plate 62 is arranged on the side of the cleaning scraper 5 close to the scraper seat 2, so as to reduce the influence on disassembly and replacement of the cleaning scraper 5. Therefore, the fixing nuts between the scraper mounting fixing plate 62 and the cleaning scraper 5 can be shared.

[0030] In addition, the cleaning scraper 5 comprises a scraper blade 51 for abutting against the conveying belt, a plurality of combing grooves 52 are arranged on the belt-facing surface of the scraper blade 51, and the combing grooves 52 are used to separate the scraper blade 51 into cleaning combs 53. The scraper blade 51 is also formed in a comb type by the combing grooves 52, so that the impact pressure on the materials on the conveying belt can be improved, that is, the cleaning strength is increased, and the cleaning effect is improved. The cleaning scraper 5 is formed in a comb type by the combing grooves 52, so that the strength of the cleaning scraper 5 can be ensured, and the cleaning strength of the cleaning combs 53 can be ensured.

[0031] Preferably, the cleaning scraper 5 is arranged obliquely to the conveying direction of the conveying belt, by which oblique arrangement, the normal impact component of the material on the cleaning scraper 5 is reduced, both the damage of the cleaning scraper 5 by the impact and the cleaning ability of the cleaning scraper 5 are improved; in addition, it is also beneficial to the superposition of adjacent cleaning scrapers 5 in the conveying direction, to ensure the full coverage of the cleaning.

[0032] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
