Description

Technical Field

[0001] This utility model relates to the field of industrial conveying equipment technology, and in particular to a protective cover for the lower idler roller of a conveyor and a protective structure for the lower idler roller of a conveyor. Background Technology

[0002] In industrial conveying systems, conveyors, as the core equipment for material transfer, directly impact production efficiency and maintenance costs due to their operational stability and safety. Lower idlers, as key support components at the bottom of the conveyor belt, are constantly exposed to complex operating conditions and face multiple challenges.

[0003] First, traditional lower idlers lack effective protection and are susceptible to intrusion of external objects (such as stones, tools, branches, etc.), leading to idler jamming, accelerated wear, and even mechanical failure, significantly increasing equipment downtime and maintenance costs. Second, during conveying, materials may leak from the conveyor belt edge into the area below the idlers, resulting in resource waste and cleaning burden. Furthermore, exposed rotating idlers pose a safety hazard to operators, with a high risk of clothing or limbs accidentally getting caught in them during operation, leading to frequent workplace injuries.

[0004] Existing protective shield designs often have the following defects:

[0005] Complex structure and inconvenient disassembly: Most protective covers adopt an integral welding or fixed structure, requiring special tools or disassembly of multiple components for maintenance, which is time-consuming and labor-intensive and affects equipment utilization.

[0006] Imbalance between protection and breathability: Some protective covers are fully enclosed, which can block foreign objects but leads to dust accumulation, clogging the idler roller area and aggravating equipment wear; while open designs cannot effectively intercept large-sized debris.

[0007] To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention

[0008] To address the aforementioned problems, the present invention aims to provide a conveyor lower idler roller protective cover and a conveyor lower idler roller protective structure that are easy to disassemble, and has the advantages of simple structure, convenient disassembly and assembly, balance between protection and breathability, high installation stability and strong adaptability.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] This application provides a conveyor lower idler roller protective cover that is easy to disassemble. The technical solution is as follows: The protective cover body is semi-cylindrical, and its surface is evenly distributed with mesh holes to block large foreign objects from entering the idler roller area, while allowing fine dust to pass through; each of the four corners of the protective cover body is provided with a connecting piece, and the connecting piece is provided with a through hole; bolts pass through the through holes to fix the protective cover to the main frame of the conveyor, so as to realize quick installation and disassembly.

[0011] Furthermore, this application also proposes that the protective cover body includes an arc-shaped curved first mesh and two semi-circular second meshes; the two second meshes are integrally welded to both ends of the first mesh, and the curvature of the first mesh is adapted to the semi-circular edge of the second mesh; the surfaces of the first mesh and the second mesh are uniformly distributed with mesh holes.

[0012] Furthermore, this application also proposes that it includes two U-shaped clamps, which are respectively welded to the joint between the first mesh and the second mesh; the two ends of the U-shaped clamps extend out of the protective cover body to form the connecting piece.

[0013] Furthermore, this application also proposes that the first and second mesh sheets are made of stamped steel plates and coated with an anti-rust coating.

[0014] Furthermore, this application also proposes that the aperture of the mesh holes ranges from 5 to 20 mm, in order to balance the efficiency of foreign object obstruction and dust passage.

[0015] Furthermore, this application also proposes that the bolt is a wing bolt, which supports manual operation to achieve quick disassembly without tools.

[0016] Furthermore, this application also proposes a lower idler roller protection structure for a conveyor, comprising: a conveyor body; an upper idler roller bracket fixed above the conveyor body, and an upper idler roller rotatably positioned on the upper idler roller bracket; a lower idler roller bracket fixed below the conveyor body, and a lower idler roller rotatably positioned on the lower idler roller bracket; and the aforementioned lower idler roller protective cover, wherein the protective cover is fixed to the lower end face of the conveyor body and houses the lower idler roller bracket and the lower idler roller cover therein.

[0017] As can be seen from the above, the conveyor lower idler roller protective cover and conveyor lower idler roller protective structure provided by this application achieve quick installation and disassembly through the design of the semi-cylindrical protective cover body, connecting piece and bolts. It solves the problems of complex structure and inconvenient disassembly and assembly of traditional protective covers. It has the advantages of simple structure, convenient disassembly and assembly, balance between protection and breathability, high installation stability and strong adaptability.

[0026] Example 1:

[0027] like Figure 1 As shown, this embodiment relates to a detachable conveyor lower idler roller protective cover, including a semi-cylindrical protective cover body 1 with uniformly distributed mesh holes on its surface. This mesh is used to block large foreign objects from entering the idler roller area while allowing fine dust to pass through. Connecting pieces 3 are provided at each of the four corners of the protective cover body 1, and through holes 4 are provided on the connecting pieces 3. Bolts pass through the through holes 4 to fix the protective cover to the conveyor main frame, enabling quick installation and disassembly. The semi-cylindrical design of the protective cover body 1 effectively covers the idler roller area, preventing large foreign objects from entering. The uniformly distributed mesh holes on the surface block large foreign objects while allowing fine dust to pass through, preventing dust accumulation and blockage in the idler roller area. The connecting pieces 3 and through holes 4 at the four corners of the protective cover body 1, combined with the use of bolts, allow for quick installation and disassembly of the protective cover, facilitating maintenance and replacement. Therefore, this technical solution, through the semi-cylindrical design and mesh hole distribution of the protective cover body 1, solves the balance problem between blocking foreign objects and allowing dust to pass through in the conveyor lower idler roller protective cover. Meanwhile, the design of the connecting piece 3 and bolts allows for quick installation and removal of the protective cover, improving maintenance efficiency. Compared with existing technologies, this solution has significant advantages in terms of protective effect and convenience, effectively enhancing the operational stability and safety of the conveyor.

[0028] like Figure 1As shown, the protective cover body 1 includes an arc-shaped curved first mesh 6 and two semi-circular second meshes 7. The two second meshes 7 are integrally welded to both ends of the first mesh 6, and the curvature of the first mesh 6 matches the semi-circular edges of the second meshes 7. The surfaces of the first mesh 6 and the second meshes 7 are evenly distributed with mesh holes (not shown in the figure). Specifically, the arc-shaped curved design of the first mesh 6 allows it to better conform to the curved surface of the idler roller, ensuring close contact between the protective cover and the idler roller, thus providing effective protection. The semi-circular design of the second meshes 7 further enhances the structural stability of the protective cover and is connected to the first mesh 6 by integral welding, simplifying the manufacturing process. The even distribution of mesh holes not only blocks large foreign objects from entering the idler roller area but also allows fine dust to pass through, thus solving the problem of imbalance between protection and breathability. Therefore, this technical solution, by optimizing the structural design of the protective cover, makes it more modular, facilitating quick installation and disassembly, and solving the technical problems of complex structure and inconvenient assembly and disassembly of traditional protective covers. Compared with existing technologies, this solution not only simplifies the manufacturing process of the protective cover, but also improves its protective effect and breathability, thereby enhancing the overall performance of the conveyor.

[0029] Furthermore, it also includes two U-shaped clamps 8, which are welded to the joint between the first mesh 6 and the second mesh 7, respectively. The two ends of the U-shaped clamps 8 extend out of the protective cover body 1, forming connecting pieces 3. As a connector, the U-shaped clamps 8 are designed in a U-shape to effectively wrap and fix the joint between the first mesh 6 and the second mesh 7. The two ends of the U-shaped clamps 8 extend out of the protective cover body 1 to form connecting pieces 3. This design not only simplifies the structure of the connecting pieces 3 but also enhances their strength. The welding method for the U-shaped clamps 8 can be arc welding, laser welding, or other suitable welding processes to ensure the strength and durability of the weld. In addition, the material of the U-shaped clamps 8 can be high-strength steel or stainless steel to further improve its tensile strength and corrosion resistance. Through the above technical solution, the welding of the U-shaped clamps 8 significantly enhances the connection stability between the first mesh 6 and the second mesh 7, ensuring that the protective cover will not loosen or shift due to vibration or external forces during long-term use. This design not only improves the overall stability of the protective cover but also simplifies the structure of the connecting piece 3 while ensuring its strength, thus effectively solving the technical problem of the connection stability between the protective cover body 1 and the connecting piece 3. Compared with existing technologies, this technical solution has significant advantages in connection stability and structural simplification, and can significantly improve the service life and protective effect of the protective cover.

[0030] Furthermore, the first mesh panel 6 and the second mesh panel 7 are made of stamped steel plates with a rust-proof coating. The stamped steel plates, formed by die stamping, possess high strength and corrosion resistance, effectively extending the service life of the protective cover. The rust-proof coating can be applied using processes such as electrophoretic coating, spraying, or dip coating. Specifically, electrophoretic coating achieves uniform coating coverage, spraying is suitable for complex surface treatments, and dip coating is suitable for mass production. As a preferred embodiment, the rust-proof coating can be epoxy resin, polyurethane, or fluorocarbon coatings, as these materials have excellent rust resistance and weather resistance, enabling long-term stable use in complex working conditions. Therefore, by combining stamped steel plates and a rust-proof coating, the protective cover effectively resists rust, reduces maintenance frequency, and improves the overall reliability of the equipment. Compared with existing technologies, this technical solution not only solves the problem of easy corrosion of the protective cover body 1 material but also further enhances the rust-proof performance of the protective cover through material selection and surface treatment, ensuring its long-term stable use in complex working conditions.

[0031] Furthermore, this application proposes that the aperture of the mesh holes ranges from 5 to 20 mm to balance the efficiency of foreign object obstruction and dust passage. Specifically, the aperture design of the mesh holes can be achieved in various ways. For example, the apertures can be evenly distributed on the surface of the protective cover to ensure the uniformity of dust passage; or, the apertures can adopt different density distributions in different areas to adapt to the dust emission requirements under different working conditions. In addition, the shape of the apertures can also be diversified, such as circular, square, or other geometric shapes, to meet the obstruction requirements of different foreign objects. As a preferred embodiment, the edges of the apertures can be chamfered to reduce dust accumulation at the edges of the holes, further improving dust passage efficiency.

[0032] To address this issue, this application solves the balance problem between blocking large foreign objects and allowing fine dust to pass through by limiting the aperture range of the mesh holes to 5-20mm. The aperture range design effectively blocks large foreign objects that could damage the idler rollers while ensuring the smooth passage of fine dust, preventing dust accumulation and accelerated equipment wear. This technical feature, by optimizing the aperture size, achieves the best balance between foreign object blocking and dust passage efficiency, improving the overall performance of the protective cover. Compared with existing technologies, the technical solution of this application not only solves the imbalance between protection and breathability in traditional protective covers but also extends the service life of the equipment and reduces maintenance costs through a reasonable aperture design.

[0033] Furthermore, this application proposes that the bolts be wing bolts, supporting manual operation for tool-free quick disassembly. The wing bolt design allows operators to disassemble directly by hand without the need for special tools, thus simplifying the maintenance process and improving equipment utilization and maintenance efficiency. Specifically, the wing bolt head is designed in a wing shape for easy gripping and rotation by fingers, and its threaded portion mates with the through hole 4 on the protective cover connecting piece 3, allowing for the fixing and disassembly of the protective cover by manual rotation. As a preferred embodiment, the wing bolt can be made of stainless steel to improve its corrosion resistance and service life. In addition, the size of the wing bolt can be adjusted according to the specific needs of the protective cover to ensure a tight fit with the through hole 4 of the connecting piece 3, preventing loosening. Therefore, this application, by using wing bolts as connectors and leveraging their support for manual operation, achieves quick disassembly of the protective cover without the need for special tools, thereby simplifying the maintenance process and improving equipment utilization and maintenance efficiency. The wing bolt design allows operators to disassemble directly by hand, reducing the use of tools and lowering operational difficulty and time costs. Compared with the prior art, the technical solution of this application not only ensures the stable installation of the protective cover, but also significantly improves the ease of disassembly and reduces the time and manpower consumption in the maintenance process, thus having high practicality and innovation.

[0034] Example 2:

[0035] like Figure 2 As shown, this embodiment also proposes a lower idler roller protection structure for a conveyor, including a conveyor body 10; an upper idler roller bracket 11 fixed above the conveyor body 10, and an upper idler roller 12 rotatably positioned on the upper idler roller bracket 11; a lower idler roller bracket 13 fixed below the conveyor body 10, and a lower idler roller 14 rotatably positioned on the lower idler roller bracket 13. This solution adopts the lower idler roller protective cover described in Embodiment 1. The protective cover is fixed to the lower end face of the conveyor body 10, and covers the lower idler roller bracket 13 and the lower idler roller 14 within it.

[0036] This solution effectively solves the technical problems of conveyor lower idlers being susceptible to foreign object intrusion, material leakage, and operational safety hazards in complex working environments by fixing a protective cover to the lower end face of the conveyor body 10 and enclosing the lower idler bracket 13 and the lower idler 14 within it. The protective cover design can block external foreign objects from entering the idler area, preventing idler jamming and wear, while reducing material leakage and cleaning burden. In addition, the fixing method of the protective cover ensures the stability of the installation, prevents the protective cover from shifting under long-term vibration, and improves the protective effect. In this way, the technical solution of this application achieves comprehensive protection for the lower idler 14, improving the operational stability and safety of the conveyor.
