According to the different cleaning positions, forces and functions, the sweeper can be divided into a primary sweeper, a secondary sweeper and a no-load section sweeper, etc. The secondary sweeper is mainly used to supplement the cleaning of the primary sweeper, and the purpose is to clean the small residual material that is not completely scraped off after the primary cleaning. The scraper in the secondary sweeper currently mainly has two materials, polyurethane and alloy. Regardless of which material is used, the scraper and its mounting frame are mainly fixed and installed by bolt connection, such as the utility model patent with the patent number CN218144085U and the name of "secondary sweeper of conveyer belt and conveyer", the utility model patent with the patent number CN221543063U and the name of "scraper and secondary sweeper of conveyer belt". This structure has the following problems in use. First, the material scraped off during the cleaning process will also adhere to the scraper. After a certain period of use, the material on the scraper will harden and form scale, resulting in reduced cleaning ability. Currently, there is no effective means to clean the material adhered to the scraper. Second, when the scraper is replaced, the operation of disassembling the bolt is performed in the narrow space below the conveyer belt. The replacement operation itself is time-consuming. In addition, the material scraped off by the scraper during use will also adhere to or cover the mounting frame and mounting bolt, further increasing the difficulty of disassembly and replacement. Therefore, a secondary sweeper with convenient cleaning and easy disassembly and replacement is needed to solve the above problems. SUMMARY
[0003] The utility model solves the technical problem of providing a replaceable secondary sweeper with impact resistance, which is convenient to clean, easy to disassemble and replace, and has good impact resistance.

Detailed Implementation
[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.
[0019] like Figs. 1 to 4 As shown, the impact-resistant, replaceable, two-stage sweeper includes a sweeper carrier 1, which is used to be fixedly installed on the conveyor frame. Its structure can be configured according to actual needs and is not limited here. The sweeper carrier 1 includes at least one shaft structure intersecting the conveying direction, and the sweeping-related structures are disposed on this shaft structure.
[0020] The sweeper carrier 1 is equipped with several transversely arranged polyurethane arms 2. The arrangement direction of the polyurethane arms 2 is intersecting the conveying direction, and in practice, it is along the axial direction of the above-mentioned shaft structure. The transverse arrangement of the polyurethane arms 2 is such that its overall length direction is approximately transverse, rather than being limited to being completely horizontal.
[0021] The top of the sweeper carrier 1 is fixedly provided with a carrier-side insertion part 11 corresponding to each of the polyurethane arms 2. Each polyurethane arm 2 is fixedly provided with an arm-side insertion part 21 that is vertically inserted into the corresponding carrier-side insertion part 11. The polyurethane arm 2 is vertically inserted into the carrier-side insertion part 11 via the arm-side insertion part 21, forming a fixed insertion connection. Because the polyurethane material of the polyurethane arm 2 itself has a certain degree of elasticity and toughness, the insertion connection can utilize an interference fit to achieve a stable connection. Disassembly is convenient; simply remove the arm-side insertion part 21 upwards.
[0022] The carrier-side insertion part 11 in this embodiment includes two opposing carrier-side insertion pieces 12. The arm-side insertion part 21 is provided with arm-side insertion grooves 22 corresponding to the two carrier-side insertion pieces 12, and the two grooves are inserted to form a connection and fixation. Of course, the carrier-side insertion part 11 can be configured as two rod structures, and the arm-side insertion part 21 can be provided with corresponding insertion holes. The grooves or rod holes can be interchanged on the carrier-side insertion part 11 and the arm-side insertion part 21, and the effect is the same. These means should all be within the protection scope of this utility model.
[0023] Each polyurethane arm 2 has a scraper connector 3 vulcanized and fixed at its free end, and a cleaning scraper 4 is integrally fixed to the scraper connector 3. Through vulcanization and the aforementioned integral connection, the polyurethane arm 2 and the cleaning scraper 4 form an integrated connection structure that does not require any bolts. Therefore, thanks to the inherent elasticity and toughness of the polyurethane arm 2, the cleaning scraper 4 achieves good impact resistance, eliminating the need for additional springs or other structures to withstand impacts, thus simplifying assembly and disassembly. When material adheres to the cleaning scraper 4, the material can be easily shaken off by tapping the polyurethane arm 2, thanks to the elasticity and toughness of the polyurethane arm 2 and the integral connection with the cleaning scraper 4, making cleaning convenient. The polyurethane arm 2 is connected to the sweeper carrier 1 by vertical insertion. The polyurethane arm 2 itself has a certain degree of elasticity and toughness, which achieves a good connection and fixation effect, which is conducive to stable sweeping operation. When replacing, the arm-side insertion part 21 can be directly removed from the carrier-side insertion part 11. The integral connection between the polyurethane arm 2 and the sweeping scraper 4 eliminates the influence of material adhesion and covering during disassembly, making disassembly and replacement convenient.
[0024] The cleaning scraper 4 can be made of polyurethane and is vulcanized and fixed to the scraper connector 3 to form an integral part. Alternatively, the cleaning scraper 4 can be made of alloy and welded and fixed to the scraper connector 3 to form an integral part. The choice of polyurethane or alloy material depends on actual needs, and different cleaning scrapers 4 can even be made of different materials; this embodiment does not impose any restrictions.
[0025] Preferably, the polyurethane arm 2 includes a carrier connecting section 23 connected to the sweeper carrier 1, and the carrier connecting section 23 is integrally provided with a blade side connecting section 24 that bends obliquely upward. By setting the polyurethane arm 2 as a whole as a bent structure, the polyurethane arm 2 can generate better elastic deformation in the conveying direction, which can promote better impact resistance at the sweeping scraper 4.
[0026] Preferably, the upper surface of the polyurethane arm 2 is provided with an inclined guide wall 25 to prevent the scraped material from easily adhering to or even covering the polyurethane arm 2, further reducing the impact of material adhesion and covering during cleaning and disassembly. Specifically, the cross-section of the polyurethane arm 2 can be set as a triangle, with two oppositely arranged guide walls 25 naturally formed on the upper surface, and the triangular cross-section still has good support capacity.
[0027] In addition, in this embodiment, multiple cleaning scrapers 4 together constitute the scraping structure. Each cleaning scraper 4 can withstand local impacts. The cleaning scraper 4 with good impact resistance is not easily damaged. Even if it is damaged, each cleaning scraper 4 can be disassembled and replaced individually, resulting in low maintenance costs.
[0028] Preferably, the cleaning scraper 4 includes a front scraper 41 and a rear scraper 42, which are alternately arranged in the arrangement direction of the polyurethane arm 2. A superimposed scraping section 43 is provided between adjacent front scrapers 41 and rear scrapers 42. This alternating arrangement ensures that adjacent cleaning scrapers 4 are staggered in the conveying direction, and when the superimposed scraping section 43 forms a full-coverage scraping effect, the cleaning scrapers 4 experience less mutual interference in terms of impact resistance and replacement.
[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
