Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, specifically to a double-unit sweeper for industrial and mining conveyor belts. Background Technology

[0002] Conveyor belts, also known as belt conveyors, are widely used in agriculture, mining, and transportation to transport various solid lumps and powders or packaged goods. Conveyor belts offer continuous, high-efficiency, and steep-angle transport capabilities. They are safe to operate, easy to use and maintain, and inexpensive. They also shorten transport distances, reduce project costs, and save manpower and resources. However, existing conveyor belt return cleaning systems generally require two cleaners to achieve good results. Both the primary and secondary cleaners must have independent spindles for installation and operation. The primary cleaner is responsible for cleaning large lumps and most of the sticky material on the conveyor belt return; the secondary cleaner handles the finer, stickier material that the primary cleaner failed to remove.

[0003] Moreover, the key issue is that over 90% of conveyor belt head pulley covers and hopper designs currently suffer from two significant problems that deviate from actual requirements:

[0004] Firstly, the head wheel cover has limited space, and normally only one sweeper can be installed. After the main primary sweeper is installed, there is no space to install a secondary sweeper. Therefore, if a secondary sweeper is to be installed, it can only be installed outside the head wheel cover. Moreover, the scrap material swept down cannot fall into the hopper and needs to be cleaned manually. In addition, the vibration of the conveyor belt during operation makes the cleaning effect less than ideal.

[0005] Secondly, the hopper is too small, only able to receive the primary sweeper to clean the tail material. Even if the head pulley cover has a position to install a secondary sweeper, it is installed at the intersection of the drive roller shaft and the belt or further back, and the swept tail material cannot fall into the hopper and needs to be manually handled. To address this, we propose a dual sweeper for industrial and mining conveyor belts. Utility Model Content

[0006] To address the problems in the existing technology, this utility model provides a double-unit sweeper for industrial and mining conveyor belts.

[0007] The technical solution adopted by this utility model to solve its technical problem is a double-unit cleaner for industrial and mining conveyor belts, including a main shaft. The outer circumference of the main shaft is integrally constructed with a support plate frame for support, and the outer circumference of the support plate frame is snapped with a U-shaped seat for support. The outer end surface of the U-shaped seat is provided with a first-stage scraper for cleaning the conveyor belt.

[0008] The main shaft is equipped with an adjustable bushing, and there are multiple sets of bushings. The bushing is provided with an adjustable elastic module, and the elastic module is provided with a U-shaped plate for support. The end of the U-shaped plate away from the elastic module is equipped with a secondary scraper for conveyor belt cleaning.

[0009] By adopting the above technical solution, during the use of conveyor belts in industrial and mining applications, the support plate frame on the outer periphery of the main shaft facilitates the support of the U-shaped seat and the primary scraper. At the same time, the secondary scraper is also installed on the outer periphery of a set of main shafts through elastic modules and bushings, so that the surface of the main shaft has both primary and secondary scrapers. This saves space occupied during installation, and the materials cleaned by the primary and secondary scrapers can fall into the discharge hopper at the same time for easy collection.

[0010] Specifically, the outer circumference of the bushing is integrally constructed with a nut body for support, and there are two sets of nut bodies. A locking screw for limiting is screwed into the inner side of the nut body.

[0011] By adopting the above technical solution, after adjusting the elastic force of the outer elastic module of the bushing, the position of the bushing can be locked by rotating the locking screw on the outer periphery of the nut body, which facilitates the subsequent use of the secondary scraper on the outer periphery of the bushing.

[0012] Specifically, the outer periphery of the U-shaped seat is screwed with bolts that are screwed into the support plate frame, and there are multiple sets of bolts.

[0013] By adopting the above technical solution, the bolts on the outer periphery of the U-shaped seat facilitate the auxiliary fixing of the U-shaped seat and the support plate frame, so that the support plate frame can stably support the first-stage scraper, and is easy to disassemble and assemble, making it convenient to use the first-stage scraper.

[0014] Specifically, a protective rubber pad is snapped between the elastic module and the U-shaped plate.

[0015] By adopting the above technical solution, the rubber pad can reduce the scratches caused by friction between the U-shaped plate and the elastic module.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The technical solution of this application, through the design of a support frame, U-shaped seat, primary scraper, bushing, elastic module, U-shaped plate, and secondary scraper, allows the support frame on the outer periphery of the main shaft to easily support the U-shaped seat and the primary scraper during use in industrial and mining conveyor belts. At the same time, the secondary scraper is also installed on the outer periphery of a set of main shafts through the elastic module and bushing, so that the main shaft surface has both primary and secondary scrapers, which saves the space occupied during installation. In addition, the material cleaned by the primary and secondary scrapers can fall into the discharge hopper at the same time for easy collection. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figure 1-3 This utility model provides a technical solution: a double-unit cleaner for industrial and mining conveyor belts, including a main shaft 1. The main shaft 1 has an integrally constructed support plate frame 2 for support, and a U-shaped seat 3 for support is snapped onto the outer periphery of the support plate frame 2. A primary scraper 4 for cleaning the conveyor belt is provided on the outer end surface of the U-shaped seat 3. A bushing 6 for adjustment is assembled on the outer periphery of the main shaft 1, and there are multiple sets of bushings 6. An elastic module 7 for adjustment is provided on the outer periphery of the bushing 6, and a U-shaped plate 8 for support is provided on the outer periphery of the elastic module 7. A secondary scraper 9 for cleaning the conveyor belt is assembled on the end of the U-shaped plate 8 away from the elastic module 7.

[0025] During use, when using the conveyor belt in industrial and mining applications, the support plate frame 2 on the outer periphery of the main shaft 1 can easily support the U-shaped seat 3 and support the primary scraper 4. At the same time, the secondary scraper 9 is also installed on the outer periphery of a set of main shafts 1 through the elastic module 7 and the bushing 6, so that the surface of the main shaft 1 has both the primary scraper 4 and the secondary scraper 9, which saves the space occupied during installation. At the same time, the material cleaned by the primary scraper 4 and the secondary scraper 9 can fall into the discharge hopper at the same time for easy collection.

[0026] like Figure 3 As shown, the bushing 6 has an integrally constructed nut body 11 for support on its outer circumference, and there are two sets of nut bodies 11. A locking screw 12 for limiting is screwed onto the inner side of the nut body 11.

[0027] When in use, after adjusting the elasticity of the outer elastic module 7 of the bushing 6, the position of the bushing 6 can be locked by rotating the locking screw 12 on the outer periphery of the nut body 11, which facilitates the subsequent use of the secondary scraper 9 on the outer periphery of the bushing 6.

[0028] like Figure 1 and Figure 2 As shown, the outer periphery of the U-shaped seat 3 is screwed with bolts 5 that are screwed into the support frame 2, and there are multiple sets of bolts 5.

[0029] In use, the bolts 5 on the outer periphery of the U-shaped seat 3 facilitate the auxiliary fixing of the U-shaped seat 3 and the support frame 2, so that the support frame 2 can stably support the first-stage scraper 4, and is easy to disassemble and assemble, making it convenient to use the first-stage scraper 4.

[0030] like Figure 1 As shown, a protective rubber pad 10 is snapped between the elastic module 7 and the U-shaped plate 8.

[0031] During use, the rubber pad 10 helps to reduce the scratches caused by friction between the U-shaped plate 8 and the elastic module 7.

[0032] The working principle and usage process of this utility model are as follows: In use, first, install the corresponding structural components in suitable positions. During the use of the industrial conveyor belt, the support plate 2 on the outer periphery of the main shaft 1 facilitates support for the U-shaped seat 3 and supports the primary scraper 4. Simultaneously, the secondary scraper 9 is also installed on the outer periphery of a set of main shafts 1 via the elastic module 7 and the bushing 6, so that the surface of the main shaft 1 simultaneously has both the primary scraper 4 and the secondary scraper 9, saving space during installation. Furthermore, the primary scraper 4 and the secondary scraper 9... The cleaned material can fall into the hopper at the same time for easy collection. After adjusting the elasticity of the outer elastic module 7 of the bushing 6, the position of the bushing 6 can be locked by rotating the locking screw 12 on the outer side of the nut body 11, which facilitates the use of the secondary scraper 9 on the outer side of the bushing 6. The bolts 5 on the outer side of the U-shaped seat 3 facilitate the auxiliary fixation of the U-shaped seat 3 and the support frame 2, so that the support frame 2 can stably support the primary scraper 4 and is easy to disassemble and assemble, making it convenient to use the primary scraper 4.

[0033] Meanwhile, the primary scraper 4 can also be installed on the outer periphery of the main shaft 1 through the bushing 6, U-shaped plate 8, and elastic module 7, so that the primary scraper 4 and the secondary scraper 9 can stop their movements at the elastic module 7 when they work independently, so as not to affect the main shaft 1 and each can perform its own function without affecting each other. Moreover, the cleaning points of the two scraper cleaners are all cleaning the tail material on the surface of the conveyor belt supported by rollers. The conveyor belt hardly jumps, so the cleaning effect is the best. In addition, even if there is local unevenness on the belt surface, the segmented scrapers absorb the local bounce through the various elastic modules 7, keep the scraper close to the belt surface, and do not affect the normal cleaning work of other modules, thus maintaining the best contact area and achieving the best cleaning effect. This allows the double cleaner to be used more stably when cleaning industrial and mining conveyor belts.

[0034] 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 descriptions of the above embodiments and specifications 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 protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
