[0002] Long-distance conveying equipment plays a crucial role in the transfer of materials in modern industrial production. Through continuous mechanized operation, it efficiently delivers bulk or packaged goods to designated locations several kilometers or even further away. It is used in scenarios such as mines, ports, power plants, and building material factories, significantly replacing traditional vehicle transportation and greatly reducing labor costs and energy consumption. Whether it is a belt conveyor, pipeline conveying system, or cableway, these devices can adapt to complex terrain and harsh environments, ensuring the stable and safe flow of materials and effectively reducing dust pollution and material loss during transportation. They are the backbone of realizing a large-scale, automated logistics system.

[0003] Existing long-distance conveying equipment faces the prominent problem of high maintenance costs. Key components, such as drive rollers, need to be replaced entirely after wear, which is time-consuming and labor-intensive, resulting in significant downtime losses. At the same time, the equipment generally suffers from excessive energy consumption. The constant speed operation mode is difficult to adapt to changing material flow rates, resulting in a large amount of energy waste. The system control precision is insufficient and lacks flexible adjustment capabilities, failing to meet the dual requirements of modern production for conveying efficiency and flexibility. These factors together restrict the improvement of the overall efficiency of the equipment. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] like Figure 1 - Figure 6 As shown, this utility model provides a technical solution: a long-distance conveying device with adjustable material conveying speed, comprising: a bushing mechanism 2, the bushing mechanism 2 including a drive main shaft 21, fixed columns 211 connected to both sides of the drive main shaft 21, a slot 212 on the drive main shaft 21, a spline bushing 22 connected to the slot 212, a slot 3 222 on the spline bushing 22, the slot 212 on the drive main shaft 21 and the slot 3 222 on the spline bushing 22 engaging with each other, a slot 221 on the side of the spline bushing 22 away from the slot 3 222, a tenon 231 connected to the slot 221, a fan-shaped liner 23 connected to the end of the tenon 231 away from the slot 221, and a pressure plate 24 connected to one side of the bushing mechanism 2.

[0023] In this embodiment, the bushing mechanism 2 includes a drive spindle 21. Fixed posts 211 are connected to both sides of the drive spindle 21 via a high-strength transition fit. The fixed posts 211 are precisely embedded in the bearing seats of the support frame 4, forming a stable rotational support. The outer surface of the drive spindle 21 is precisely machined with continuous concave grooves 212. These grooves 212 form a tight meshing connection with the protruding grooves 222 on the inner wall of the spline bushing 22. The multi-tooth meshing spline connection can transmit enormous rotational speeds. To ensure reliable power transmission while maintaining excellent alignment accuracy, multiple grooves 221 of uniform depth are formed around the outer circumferential surface of the splined bushing 22. These grooves are evenly distributed along the axial direction of the bushing, and each groove 221 is fitted with a matching tenon 231. These tenons 231 serve as a connecting medium, and their outer sides are firmly bonded to the inner curved surface of the fan-shaped liner 23. The fan-shaped liner 23 is made of high wear-resistant composite ceramic material, and its outer surface is designed with anti-slip textures to enhance its durability. Due to friction with the conveyor belt, each liner plate is a standardized fan-shaped structure. Multiple liner plates together form a complete cylindrical working surface. The modular design allows only a single fan-shaped liner plate 23 to be replaced when there is local wear, which greatly reduces maintenance costs. A pressure plate 24 is installed at one end of the bushing mechanism 2. The pressure plate 24 is installed by fixing screws 241, which firmly presses all the fan-shaped liner plates 23 onto the spline bushing 22 to form a rigid whole. In order to facilitate maintenance operations, a support structure 3 is specially set on the equipment frame. When it is necessary to replace the fan-shaped liner plate 23, the entire bushing mechanism 2 can be placed in the positioning slot 32 of the support structure 3 for rotation operation without the need for hoisting equipment. This structural design not only ensures the stability of the transmission system, but also greatly improves the convenience of equipment maintenance, making it possible to quickly replace worn parts without stopping the machine. The entire mechanism is driven by a variable frequency motor 41 and a precision reduction device to achieve stepless adjustment of the conveying speed, meeting the conveying needs under different working conditions.

The positioning slot 32 adopts a U-shaped structure design, and its open end is provided with a reinforced fixing ring 321. The fixing ring 321 is connected to the fixing post 331 at the top of the support rod 33 by an interference fit. A slot 323 is provided on one side of the positioning slot 32, so that the support rod 33 can be stored in the slot 323 after rotating around the fixing ring 321 via the fixing post 331.

The fixed posts 211 are precisely embedded in the bearing seats of the support frame 4, forming a stable rotational support. The outer surface of the drive spindle 21 is precisely machined with continuous concave grooves 212. These grooves 212 form a tight meshing connection with the raised grooves 222 on the inner wall of the spline bushing 22. The multi-tooth meshing spline connection can transmit huge torque while maintaining excellent alignment accuracy, ensuring the reliability of power transmission. On the outer circumferential surface of the spline bushing 22, multiple grooves 221 of uniform depth are formed around it. These grooves are evenly distributed along the axial direction of the bushing. Each groove 221... Internally, each piece is fitted with a matching tenon 231. These tenons 231 serve as a connecting medium, and their outer sides are firmly bonded to the inner curved surface of the fan-shaped liner 23. The fan-shaped liner 23 is made of high wear-resistant composite ceramic material, and its outer surface is designed with anti-slip textures to enhance friction with the conveyor belt. Each liner is a standardized fan-shaped structure, and multiple liners together form a complete cylindrical working surface. The modular design allows for the replacement of only a single liner when there is local wear, significantly reducing maintenance costs. A pressure plate 24 is installed at one end of the bushing mechanism 2.

For ease of maintenance and operation, a special... A support structure 3 is provided. When the sector-shaped liner 23 needs to be replaced, the entire bushing mechanism 2 can be placed in the positioning slot 32 of the support structure 3 for rotation without the need for hoisting equipment. This structural design ensures the stability of the transmission system and greatly improves the convenience of equipment maintenance, making it possible to quickly replace worn parts without stopping the machine.
