Description

Technical Field

[0001] This utility model relates to the field of material conveying equipment technology, specifically to a belt conveyor with a rake function. Background Technology

[0002] Belt conveyors, as efficient and continuous material conveying equipment, are widely used in various industries such as mining, chemical, grain processing, and building materials. Their core function is to achieve stable material transfer between different production stages, ensuring the continuity and efficiency of the production process. However, when conveying materials with high moisture content (such as wet slag, grain with a moisture content exceeding 15%, wet fly ash, river sand, ground sand, coal slime, sand, slag, sludge, etc.), these materials are prone to adhesion and agglomeration during transport. Due to the large amount of moisture adhering to the material surface, some material will stick to the conveyor belt surface during belt conveying. This not only reduces the material conveying capacity and increases material loss during transport, but also requires regular cleaning of the conveyor belt, increasing equipment maintenance workload and costs. Furthermore, when the agglomerated material clumps enter the drying stage, the internal moisture is difficult to evaporate quickly, requiring extended drying time or increased drying temperature, directly leading to a significant increase in the energy consumption of the drying equipment. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a belt conveyor with a rake function. When conveying materials with high moisture content, the rake teeth turn the materials over, and a fan accelerates the airflow over the material's surface, thereby achieving a pre-drying effect, reducing the surface moisture of the material, and thus reducing energy consumption during drying and lowering operating costs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a belt conveyor with a raking function, comprising a frame, a conveyor belt disposed in the middle of the frame, and a material blocking module, a pre-drying module and a cleaning module disposed sequentially on the frame along the material conveying direction. The pre-drying module includes a raking device and a fan. The raking device includes a mounting bracket, a cross brace disposed on the mounting bracket, a connecting rod disposed on one side of the cross brace and a raking tooth disposed on the other side.

[0005] As a further improvement to the above technical solution:

[0006] The number of rake teeth is multiple and they are evenly distributed along the width direction of the conveyor belt.

[0007] The conveyor belt is V-shaped, and the rake teeth extend from the middle of the cross brace to both sides with a gradually decreasing height.

[0008] The width of the rake teeth gradually increases outward from the end connected to the cross brace.

[0009] The connecting rod includes a positioning rod connected to the cross brace, and an extension rod is slidably mounted on the positioning rod.

[0010] A roller is provided below the conveyor belt, and belt guide rollers that fit against the side edges of the conveyor belt are provided on both sides of the frame.

[0011] The material blocking module includes a mounting base, on which a U-shaped material blocking plate is disposed.

[0012] The cleaning module includes a scraper located at the end of the frame and a sweeping roller installed below the conveyor belt.

[0013] The upper roller of the cleaning roller is equipped with multiple sets of staggered brushes, with gaps reserved between adjacent sets of brushes.

[0014] The beneficial effects of this utility model embodiment are as follows: The belt conveyor with raking function includes a frame, a conveyor belt is arranged in the middle of the frame, and a pre-drying module is arranged on the frame. The pre-drying module includes a raking device and a fan. The raking device includes a mounting bracket, a cross brace is arranged on the mounting bracket, a connecting rod is arranged on one side of the cross brace, and a raking tooth is arranged on the other side. When conveying materials with high moisture content, the raking tooth turns the material over, and the fan accelerates the airflow on the surface of the material, thereby achieving the effect of pre-drying, reducing the surface moisture of the material, thereby reducing energy consumption during drying and reducing operating costs.

[0021] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0022] See Figure 1-5 This utility model discloses a belt conveyor with a material-raking function. The core structure is a frame 1, and the overall structure revolves around the material conveying process, with each functional module arranged sequentially along the material conveying direction. The frame 1 has a conveyor belt 2 installed in the middle, serving as the core carrier for material conveying. The conveyor belt 2 is V-shaped to better accommodate material gathering requirements. Idler rollers 10 are installed below it to support the conveyor belt 2 and ensure conveying stability. Baffle rollers 11 are also provided on both sides of the frame 1, which fit tightly against the side edges of the conveyor belt 2 to effectively prevent the conveyor belt 2 from shifting during operation. The frame 1 serves as the supporting frame for the entire device, and along the material conveying direction, a material-blocking module, a pre-drying module, and a cleaning module are sequentially assembled. Each module is fixed in position and works collaboratively through the frame 1.

[0023] The material blocking module is located at the very front of the material conveying path to limit the material's initial entry into the conveyor belt 2 and prevent spillage. This module includes a mounting base 12 fixed to the frame 1, which provides the foundation for the material blocking structure. A U-shaped material blocking plate 13 is mounted on the mounting base 12. The U-shaped material blocking plate 13 wraps around the material conveying area above the conveyor belt 2 through its U-shaped structure, thus achieving initial material blocking.

[0024] Behind the material blocking module is the pre-drying module, which has the dual functions of "raking and dispersing materials" and "drying materials", which can improve the efficiency of subsequent material processing. It consists of a raking device and a fan 3. In the raking device, the mounting bracket 4, fixed on the frame 1, is an integral support component. The mounting bracket 4 is equipped with a cross brace 5, which provides a connecting carrier for the rake teeth 7 and the connecting rod 6. Different components are installed on both sides: one side is equipped with a connecting rod 6 for adjusting the position or length of the cross brace 5. The connecting rod 6 consists of a positioning rod 8 directly connected to the cross brace 5 and an extension rod 9 slidably sleeved on the positioning rod 8. By sliding the extension rod 9 on the positioning rod 8, the overall coverage of the raking device can be flexibly adjusted; the other side is equipped with rake teeth 7 for raking and dispersing materials on the conveyor belt. The structure of the rake teeth 7 is adapted to the V-shaped conveyor belt 2. There are multiple rake teeth 7, which are evenly distributed along the width of the conveyor belt 2 to ensure uniform raking. The height gradually decreases from the middle of the cross brace 5 to both sides, adapting to the inclined side of the V-shaped conveyor belt 2. The width gradually increases from the end connected to the cross brace 5 to the outside, which can further improve the effect of raking and dispersing materials.

[0025] The cleaning module is located at the end of the frame 1 and is mainly used to clean the residual material on the surface of the conveyor belt 2 to prevent material accumulation from affecting subsequent conveying. The module includes two core components: a scraper 14 that acts directly on the surface of the conveyor belt 2 and can scrape off the firmly attached material on the conveyor belt 2, and a cleaning roller 15 installed below the conveyor belt 2. The cleaning roller 15 is equipped with multiple sets of brushes 16, which are staggered and have gaps between adjacent sets of brushes 16. This design can clean the bottom of the conveyor belt 2 with the brushes 16 and prevent the cleaned material from clogging the cleaning roller 15 through the gaps.
