[0035] Please refer to Figures 1 to 8 , a scrap steel conveyor line, including a frame, a driving wheel and a redirecting wheel respectively arranged at both ends of the frame, a conveyor belt 8 wound around the driving wheel and the redirecting wheel, and a driving device 10 connected to the driving wheel. A number of U-shaped baffles 13 connected to it are successively arranged along the length direction of the conveying side of the conveyor belt 8. The U-shaped baffles 13 have good wear resistance and are made of hard wear-resistant materials. Adjacent U-shaped baffles 13 are connected by a flexible seal 14 to form a material conveying channel.

[0036] The present invention is suitable for the large-capacity, long-distance continuous conveying of scrap steel and other materials with sharp edges and strong abrasiveness, optimizes the transportation mode of scrap steel materials, improves the logistics efficiency, reduces the logistics cost, enhances the economy, and improves the on-site operation environment.

[0037] In order to reduce the maintenance cost, the conveyor belt of the present invention adopts a split design. The conveyor belt 8 includes a base belt 11 and an intermediate belt 12 arranged on the side of the base belt facing the U-shaped baffle 13. The intermediate belt 12 is a split structure and includes a number of segmented belts connected end to end. Preferably, one segmented belt corresponds to one U-shaped baffle 13, and adjacent segmented belts are overlapped end to end, and the overlapping length is the length of a single U-shaped baffle 13. Figure 5The separated states of the base belt 11, the intermediate belt 12, and the U-shaped baffle 13 are shown, intuitively presenting the positional relationship and shapes of the three. The connection method between the intermediate belt 12 and the base belt 11 can adopt an adhesive bonding method. Specifically, all contact surfaces between the two are adhesively bonded, which can avoid damage to the base belt 11 and extend its service life. The intermediate belt 12 and the U-shaped baffle 13 can adopt bolt connection. Specifically, at least 2 groups or more of bolts are used for connection at the middle position and both ends of the contact surface between the two. The number of groups is determined according to the length of the U-shaped baffle 13, and the number of bolts in each group is determined according to the width of the U-shaped baffle 13. It can also adopt a combined method of adhesive bonding and bolt connection. Specifically, all contact surfaces between the two are adhesively bonded, and at the same time, at least 2 groups or more of bolts are used for connection at both ends, which is convenient for the smooth transition at the head and tail arc sections. The conveyor belt adopting the above-mentioned split structure can effectively avoid damage to the base belt 11, and is convenient for the maintenance of the intermediate belt 12 and the U-shaped baffle 13, reducing the later operation and maintenance costs.

[0038] In order to achieve a smooth transition of the arc section of the conveyor belt 8, there should be a gap between adjacent U-shaped baffles 13 in the present invention, and the flexible seal 14 is arranged in the gap between adjacent U-shaped baffles.

[0039] In order to monitor whether the return section of the conveyor belt 8 is carrying materials, the present invention is provided with a material carrying detection device 2, and the material carrying detection device 2 is located below the discharging end of the conveying line. The material carrying detection device 2 can detect and judge in real time whether the return section of the conveyor belt is carrying materials and take corresponding actions.

[0040] In order to ensure that the conveyor belt 8 has sufficient tension, the present invention is provided with a tensioning device 6, and the tensioning device 6 can adopt a general vehicle-type screw tensioning device or a tower tensioning device.

[0041] The present invention is provided with a set of idler wheels 5, and the set of idler wheels 5 includes a number of first idler wheels arranged at intervals on the lower side of the load-carrying section of the conveyor belt 8 to support the operation of the conveyor belt 8 carrying materials, and a number of second idler wheels arranged at intervals on the lower side of the return section of the conveyor belt 8 to reduce the sag of the return section; the spacing between the second idler wheels is greater than the spacing between the first idler wheels, and both ends of the second idler wheels and the first idler wheels are supported on the frame.

[0042] In order to improve the flexibility of the conveyor line layout, the frame in the present invention adopts a split structure. The frame includes a bracket 4 corresponding to the position of the conveyor belt and a head bracket 1 and a tail bracket 7 respectively located at the front and rear ends of the bracket; both ends of the redirecting wheel are supported on the tail bracket 7, and the redirecting wheel is connected to the tensioning device 6 arranged on the tail bracket 7 to adjust the position of the redirecting wheel through the tensioning device 6 to achieve the tensioning of the conveyor belt 8; both ends of the driving wheel are supported on the head bracket 1, and the driving wheel is connected to the driving device 10 arranged on the head bracket 1 to drive the driving wheel to rotate through the driving device 10; both ends of the second idler wheels and the first idler wheels are supported on the bracket of the frame.

[0043] In order to increase the wrap angle between the conveyor belt 8 and the driving wheel, the present invention is provided with a wrap angle increasing and redirecting device 3, which increases the wrap angle between the conveyor belt 8 and the driving wheel and improves the transmission efficiency.

[0044] The discharging end of the conveying line of the present invention is provided with a discharging device 9, which is installed on the head support 1 at the discharging end of the conveying line, and the materials on the conveyor belt 8 fall onto the downstream conveying equipment through the discharging device 9.

[0045] The conveyor belt 8 of the present invention is driven by a driving device 10. After being tensioned and redirected by a tensioning device 6, it forms a continuous circular operation, so that the materials falling on the loading section of the conveyor belt 8 are continuously transported from the tail feeding end to the discharging device 9 and fall onto the downstream conveying equipment, realizing the fast and continuous transportation of materials. The present invention is convenient for docking with external units such as scrap yards and steel mills, facilitating the production organization and automated and intelligent management in the factory area, ensuring the stability of scrap steel distribution and improving the production operation efficiency; it is also convenient to be used in cooperation with closed corridors and dust removal facilities, improving the operation environment, enhancing labor safety and industrial hygiene, and creating a green, environmentally friendly, intelligent and efficient scrap steel industry.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the present technical solution, and they should all be covered within the scope of the claims of the present invention.
