[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Example 1

[0028] Reference Figure 1 A conveyor belt system for underground coal mines includes: a main support frame 1, a conveying mechanism, and limiting components 6. The conveying mechanism is mounted on the main support frame 1, and the limiting components 6 are located on both sides of the conveying mechanism. The conveying mechanism is used to transport materials from underground coal mines to the outside. The limiting components 6 are used to restrict the movement of materials on the conveying mechanism to both sides in the direction of transport, preventing the materials from shifting or scattering during transport, thereby improving the stability and reliability of material transport. The main support frame 1, as the basic support structure of the entire device, bears the weight and pressure of the transported materials and is made of metal, such as steel or alloy, to ensure its stability and durability.

[0029] In this embodiment, the transport mechanism includes a drive assembly 2, a transmission assembly, and a conveyor belt assembly 3. The drive assembly 2 is connected to the transmission assembly, which is mounted on the main support 1 along the transport direction. The conveyor belt assembly 3 is connected to the transmission assembly to form a conveyor belt structure. Limiting components 6 are located on both sides of the conveyor belt assembly 3. The drive assembly 2 can consist of components such as a motor and a reducer. The motor drives the roller to rotate through the reducer, thereby driving the conveyor belt assembly 3 to move. The conveyor belt assembly 3 can be made of a high-strength, wear-resistant conveyor belt material.

[0030] In this embodiment, the transmission assembly includes a roller, a first roller assembly, and a second roller assembly. The drive assembly 2 is connected to the roller. The first roller assembly is in contact with the advancing portion of the conveyor belt assembly 3, and the second roller assembly is in contact with the returning portion of the conveyor belt assembly 3, ensuring smooth operation of the conveyor belt assembly 3. The roller is located at the discharge end in the material transport direction. By driving the conveyor belt assembly 3 with the roller, the conveyor belt assembly 3 drives the first roller assembly and the second roller assembly to roll, thereby achieving continuous material transport.

[0031] In this embodiment, the first roller assembly includes several first rollers 4. Every two first rollers 4 form a V-shaped roller in space. The several V-shaped rollers are spaced apart along the material transport direction. The contact surface between the tape assembly 3 and the V-shaped rollers is V-shaped, which helps to better support the tape and guide the tape through the V-shaped structure, helping the tape to remain stable during transport.

[0032] In this embodiment, the second roller assembly includes a plurality of second rollers 5, which are spaced apart along the material transport direction. This helps maintain the tension of the conveyor belt and prevents the conveyor belt from slackening or deviating from the track during the return journey.

[0033] In this embodiment, each second roller 5 is positioned between every two V-shaped rollers in the space, and the second roller 5 is located below the V-shaped rollers. The second rollers provide an additional support effect for the tape assembly 3.

[0034] In this embodiment, a control component 7 is also included. The control component 7 is mounted on the main support 1, and the transport mechanism is connected to the control component 7. A control panel is provided on the control component 7. Operators can start, stop, or adjust the operating speed of the transport mechanism using buttons or knobs on the control panel of the control component 7.

[0035] Example 2

[0036] Based on Embodiment 1, in this embodiment, the limiting component 6 includes an adjusting component and a baffle 601. The adjusting component is disposed on both sides of the transport mechanism, and the baffle 601 is detachably connected to the adjusting component. The cross-section formed by the baffle 601 and the tape component 3 is U-shaped. The baffle 601 can be made of a high-strength, wear-resistant metal material, such as steel or alloy, to ensure its stability and durability.

[0037] In this embodiment, the baffle 601 is a curved baffle. The curved design helps to better fit the tape assembly 3 and reduce material shifting and scattering during transportation. Several rows of adjustment holes are provided on the baffle 601, each row of holes being adapted to the adjustment component. By selecting different adjustment holes, the position and angle of the baffle 601 can be adjusted to adapt to the needs of different materials and transportation conditions. The adjustment component is installed on both sides of the tape assembly 3, ensuring that the position and angle of the adjustment component meet the design requirements. The initial position of the baffle 601 is determined, and bolts and nuts are used to fix the baffle 601 to the adjustment component through the adjustment holes. Based on the actual material and transportation conditions, the shifting and scattering of the material during transportation are observed. The bolts and nuts are loosened using tools, and the position and angle of the baffle 601 are adjusted to better fit the tape assembly 3, reducing material shifting and scattering. After adjustment, bolts and nuts are used again to fix the baffle 601 to the adjustment component, ensuring the stability and reliability of the baffle 601. The baffle 601 model can be changed according to the type and size of the material to meet the transportation requirements of different materials.

[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
