Description

Technical Field

[0001] This utility model relates to the technical field of inclined belt conveyor equipment, specifically to an inclined belt conveyor device. Background Technology

[0002] Belt conveyors primarily use a conveyor belt to transport materials. Materials enter the conveyor belt from the feed hopper and are transported to the other end of the conveyor. They are widely used in metallurgy, coal mining, and transportation industries due to their advantages such as large conveying capacity, simple structure, convenient maintenance, low cost, and strong versatility. To achieve stable material transport, the conveying angle of a belt conveyor is typically 0°≤a≤20°. However, this often fails to meet the requirements of current coal mining environments, leading to the use of steeply inclined belt conveyors. When a steeply inclined belt conveyor operates at a constant speed, theoretically, the raw coal on the conveyor belt is stationary due to frictional resistance between the raw coal and the conveyor belt. However, because the inclination angle of the conveyor exceeds the dynamic angle of repose of the raw coal, the raw coal on the conveyor belt will slide down under the influence of mechanical vibration and other factors. The speed of this slide is directly proportional to the distance between the raw coal and the contact surface of the conveyor belt. The sliding speed of the raw coal in the upper layer is the greatest. The larger the inclination angle, the faster the sliding speed. The material rolling off the conveyor damages the equipment and reduces conveying efficiency.

[0003] To address the aforementioned problems, the following methods are typically employed: First, patterned conveyor belts are used to increase friction between the belt surface and the material. However, the special surface structure of the conveyor belt increases manufacturing costs, and surface cleaning is difficult, requiring specialized vibratory cleaning devices, thus limiting its application. Second, transverse baffles are added to the conveyor belt. This special structure reduces the belt's strength and shortens its lifespan, and cleaning remains a challenge. Therefore, developing a high-angle belt conveyor with a long service life, high reliability, and high conveying efficiency is objectively necessary. Utility Model Content

[0004] The purpose of this utility model is to provide a high-angle belt conveyor with long service life, safety and reliability, and high conveying efficiency.

[0005] The purpose of this utility model is achieved as follows: it includes an inclined frame and a deep groove idler roller group and a conveyor belt mounted on the frame. The conveyor belt includes a feeding section and a conveying section from the feeding end to the discharging end. A chain plate conveyor is arranged parallel above the conveying section. Several partitions are arranged at intervals along the conveying direction on the chain plate of the chain plate conveyor. The ends of the partitions are arc-shaped. The arc of the ends of the partitions matches the arc of the conveyor belt in the deep groove idler roller group. A gap is left between the ends of the partitions and the conveyor belt. Several side baffles are arranged sequentially on both sides of the chain plate of the chain plate conveyor.

[0006] Furthermore, insert plates and insertion holes are provided on both sides of the baffle.

[0007] Furthermore, the ends of the partition are provided with several sharp teeth.

[0008] Furthermore, the spacing of the deep trough idler groups in the feeding section is smaller than the spacing of the deep trough idler groups in the conveying section.

[0009] Furthermore, splash guards are installed on the frames on both sides of the feeding section.

[0010] Furthermore, a cleaning brush is installed on the frame below the discharge end of the conveyor belt.

[0011] In use, this invention simultaneously starts the conveyor belt and the chain plate conveyor above it, ensuring that both the upper belt and the lower chain plate of the chain plate conveyor have the same conveying speed and move upwards. Materials such as coal fall from the hopper onto the conveyor belt in the feeding section, and are then conveyed to the conveying section. The baffles on the chain plate conveyor are inserted into the material, separating the material on the conveyor belt into sections. This prevents the coal from sliding down and pushes the material upwards, causing it to fall from the discharge end of the conveyor belt, thus completing the conveying of the coal. In this invention, the partitions rotate at the lower end of the chain conveyor and eventually insert into materials such as coal during rotation. Several partitions divide the material on the conveyor belt into multiple segments, with each partition supporting the material in its corresponding segment. When material slides down, it is blocked and supported by the partitions, preventing further downward movement and thus protecting the equipment from damage. Simultaneously, the partitions move with the chain conveyor, exerting an upward pushing force on the material, assisting the conveyor belt in transporting the material and reducing the conveying load on the belt to a certain extent, thus improving the material transport efficiency. Furthermore, the partitions have a certain gap between their ends and the conveyor belt, preventing damage to the belt. Side baffles are also installed on both sides of the chain conveyor, which can further regulate the material on the conveyor belt. This invention uses a barrier to prevent materials from rolling off the sides of the conveyor belt. The area on the conveyor belt is divided into several relatively sealed zones. Adjacent partitions, side baffles between partitions, and the conveyor belt itself form a relatively sealed material cavity. Materials are conveyed within these cavities, preventing material from falling off during transport. This makes the conveying process safer, more reliable, and more efficient. Furthermore, compared to existing technologies, this invention does not include partitions or side baffles on the conveyor belt, thus not affecting its structure or strength. On the contrary, it reduces the conveying load and extends the belt's lifespan. Simultaneously, the absence of partitions and side baffles on the conveyor belt makes cleaning easier and faster, eliminating the need for special cleaning devices; existing conveyor belt cleaning devices can be used without limitation. In summary, this invention offers advantages such as long service life, safety and reliability, and high conveying efficiency. Attached Figure Description

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings, but this description is not intended to limit the present invention in any way. Any changes or improvements made based on the present invention shall fall within the protection scope of the present invention.

[0014] like Figures 1-4 As shown, this utility model includes an inclined frame 1, a deep-groove idler roller group 2, and a conveyor belt 3 mounted on the frame 1. The structure of the frame 1, the deep-groove idler roller group 2, and the conveyor belt 3 is existing technology and is used for conveying materials such as coal. The conveyor belt 3 includes a feeding section and a conveying section from the inlet end to the outlet end. The feeding section is used for feeding materials. Generally, a hopper is located above the feeding section. During operation, materials fall from the hopper onto the feeding section of the conveyor belt 3. The conveying section is used for conveying materials. The material conveying section is relatively short, just enough to meet the feeding requirements. A chain conveyor 4 is installed parallel above the material conveying section. The chain conveyor 4 is an existing device. Several baffles 5 are spaced along the conveying direction on the chain plate of the chain conveyor 4. The ends of the baffles 5 are arc-shaped, and the arc of the ends of the baffles 5 matches the arc of the conveyor belt 3 in the deep trough idler group 2. A gap is left between the ends of the baffles 5 and the conveyor belt 3. Several side baffles 6 are arranged sequentially on both sides of the chain plate on the chain conveyor 4. Compared with the traditional material conveying structure, this utility model eliminates the structure of setting baffles 5 and side baffles 6 on the conveyor belt 3, which can avoid the reduction of the strength of the conveyor belt 3, so that it has a better stress condition and thus extends the service life of the conveyor belt 3.

[0015] In use, this invention simultaneously starts the conveyor belt 3 and the chain conveyor 4 above it, ensuring that both the upper belt of the conveyor belt 3 and the lower chain conveyor 4 move at the same conveying speed and both move upwards. Materials such as coal fall from the hopper onto the conveyor belt 3 in the feeding section, and are then conveyed by the conveyor belt 3 to the conveying section. The baffles 5 on the chain conveyor 4 insert into the material, separating the material on the conveyor belt 3 into segments. This prevents the coal from sliding down and pushes the material upwards, allowing it to fall from the discharge end of the conveyor belt 3, thus completing the conveying of the coal. In practical use, this invention can also employ an intermittent feeding method, positioning the baffles 5 between corresponding material drops. This avoids the baffles 5 inserting into the material, improving the stability of material conveying. In this invention, the partitions 5 rotate at the lower end of the chain conveyor 4, eventually inserting into materials such as coal during rotation. Several partitions 5 divide the material on the conveyor belt 3 into multiple segments, each partition 3 supporting the material in its corresponding segment. When the material slides down, it is blocked and supported by the partitions 5, preventing further downward movement and thus protecting the equipment from damage. Simultaneously, the partitions 5 move with the chain conveyor 4, exerting an upward pushing force on the material, assisting the conveyor belt 3 in conveying the material and reducing its load to some extent, thus improving conveying efficiency. Furthermore, the partitions 5 have a certain gap between their ends and the conveyor belt 3, and since they move at the same speed and in the same direction while remaining relatively stationary, the partitions 5 will not damage the conveyor belt 3. Side baffles 6 are also installed on both sides of the chain conveyor 4, which can block the material on the conveyor belt 3. To prevent materials from rolling off the sides of the conveyor belt 3, the area on the conveyor belt 3 is divided into several relatively sealed areas. That is, a relatively sealed material cavity is formed between two adjacent partitions 5, the side baffles 6 between two partitions 5, and the conveyor belt 3. The material is conveyed in each material cavity, and no material will fall off during the conveying process. The conveying process is safer and more reliable, and the conveying efficiency is also higher. Moreover, the relatively sealed material cavity can also reduce the spread of dust to a certain extent. In addition, compared with the prior art, the partitions 5 and side baffles 6 are not set on the conveyor belt 3 in this utility model. It will not affect the structure of the conveyor belt 3, nor will it reduce the strength of the conveyor belt 3. On the contrary, it will reduce the conveying load of the conveyor belt 3 and increase the service life of the conveyor belt 3. At the same time, since no partitions 5 and side baffles 6 are added to the conveyor belt 3, it is more convenient and quick to clean. No special cleaning device is required. The existing conveyor belt 3 cleaning device can be used, and its use is unrestricted.

[0016] The side baffles 6 are respectively provided with insert plates 7 and insertion holes 8 on both sides. In this utility model, the side baffles 6 are used to block the material on the conveyor belt 3 and prevent the material from rolling off the sides of the conveyor belt 3. In actual use, it was found that the material exerts an outward pushing force on the side baffles 6. This pushing force causes the lower part of the side baffles 6 to tilt to a certain extent, causing some material to slide to the side. After the insert plates 7 and insertion holes 8 are provided, the insert plates 7 will automatically insert into the insertion holes 8 of the adjacent side baffles 6, thereby connecting several side baffles 6 into a whole, improving the overall rigidity and strength, making it less prone to outward tilting and deformation, and thus improving the problem of material sliding to the sides.

[0017] The end of the partition 5 is provided with several sharp teeth 9. The end of the partition 5 will be inserted into the material such as coal. The sharp teeth 9 at the end make the insertion of the partition 5 into the material smoother and faster.

[0018] The spacing of the deep trough idler group 2 in the feeding section is smaller than that in the conveying section. When this utility model is in operation, materials such as coal will fall from the corresponding hopper to the feeding section of the conveyor belt 3, which will undoubtedly have a large impact on the feeding section of the conveyor belt 3. Over time, the conveyor belt 3 is easily damaged. By shortening the spacing of the deep trough idler group 2 in the feeding section, the deep trough idler group 2 increases the support points of the conveyor belt 3, shortens the suspended length of the conveyor belt 3, thereby improving the strength of the conveyor belt 3, making it safer, and extending the service life of the conveyor belt 3.

[0019] Splash guards 10 are installed on the frame 1 on both sides of the feeding section. When this utility model is running, materials such as coal will fall from the corresponding hopper to the feeding section of the conveyor belt 3. Collisions will occur between the materials and the conveyor belt 3, and between the materials themselves, resulting in some splashing. Some materials will splash in all directions and fall off the conveyor belt 3. To prevent this, splash guards 10 are installed on both sides of the feeding section to block the materials from flying out from both sides of the conveyor belt 3.

[0020] A cleaning brush 11 is installed on the frame 1 below the discharge end of the conveyor belt 3. The cleaning brush 11 is an existing device used to brush away fine dust and materials adhering to the conveyor belt 3, keeping the conveyor belt 3 clean, and preventing fine dust from falling to other parts of the equipment and causing pollution. In actual use, the cleaning brush 11 can be a strip brush, disc brush, brush roller or other structural forms, whichever is required.
