The front end of each side roller motor 702 is rotatably connected to the main side roller gear 701, which drives the auxiliary side roller gear 7 to rotate. Each main side roller gear 701 meshes with the auxiliary side roller gear 7 at its bottom. A protective roller connecting strip 802, made of alloy material, is fixed to the top of each reversing plate 504. The protective roller connecting strip 802 is used to position the protective roller positioning plate 801. A protective roller positioning plate 801, also made of alloy material, is fixed to the top of each protective roller connecting strip 802.The protective idler roller positioning plate 801 is used to position the protective idler roller 8. Each protective idler roller positioning plate 801 is rotatably connected to the protective idler roller 8 inside it. A belt 101 is provided between the protective idler roller 8 and the side idler roller 5. The belt 101 is used to transport materials and is in close contact with the bottom idler roller 501. A side idler roller spring 505 is fixed to the bottom of each side idler roller positioning plate 502.

The right end of the bottom idler roller spring 506 is fixedly connected to the right bottom idler roller positioning plate 503.

[0027] When using this device, the operator can fix the support frame 2 using the connecting plate 203. At this time, the operator controls the side idler roller motor 702 according to the required troughing angle, thereby driving the side idler roller main gear 701 to rotate, which in turn drives the idler roller secondary gear 7 to rotate, which in turn drives the reversing plate 504 to rotate, which in turn drives the protective idler roller connecting strip 802 to rotate, which in turn drives the protective idler roller positioning plate 801 to rotate, which in turn drives the protective idler roller 8 to rotate. This makes the side idler roller 5 and the protective idler roller connecting strip 802 perpendicular. Since the reversing plate 504 rotates, the side idler roller positioning plate 502 rotates, thus... When the side roller 5 rotates, the bottom roller 501 rotates accordingly due to the action of the main buckle 507 and the secondary buckle 508 connecting the side roller. Simultaneously, the angles of the two bottom roller positioning plates 503 can be changed by the action of the secondary buckle 509 and the main buckle 510 connecting the bottom roller, thus ensuring the variable angle of the groove. Furthermore, the stability of the entire device is ensured by the action of the side roller spring 505 and the bottom roller spring 506. The operator then installs the belt 101 on top of the bottom roller 501. The position of the belt 101 can be monitored by the camera 306. The belt 101 controls the operation of the adapter motor 403, thereby driving each pressure roller 602 to be parallel to its bottom side roller 5 and bottom roller 501, thus ensuring the accuracy of belt pressing. Furthermore, the belt 101 controls the extension of the pressure rod 6, thereby driving the pressure roller 602 to move downwards, making the pressure roller 602 tightly adhere to the belt 101 and apply force to it. At this time, the pressure sensor 402 monitors the pressure applied by the pressure roller 602, thus ensuring that the belt 101 is tightly adhered to the side roller 5 and bottom roller 501 according to the material weight, while preventing damage to the belt 101. When the material moves to the bottom of the support frame 2, the belt 101 controls the reversing motor 305 to work, thereby driving the reversing main gear 304 to rotate, which in turn drives the reversing secondary gear 303 to rotate, which in turn drives the reversing rod 302 to rotate, which in turn drives the reversing block 3 to rotate, which in turn drives the positioning frame 4 to rotate, so that the pressure rod 6 rotates around the reversing rod 302, thereby facilitating material transportation. Furthermore, when the material passes the support frame 2, the belt 101 controls the reversing motor 305 to make the pressure roller 602 close to the belt 101 again, thereby achieving belt pressing again, thus ensuring the stability of material transportation.

[0028] The working process of this utility model is as follows: When using this device, the operator can fix the support frame 2 through the connecting plate 203. At this time, the operator controls the side idler roller motor 702 to work according to the required troughing angle, thereby driving the side idler roller main gear 701 to rotate, thereby driving the idler roller secondary gear 7 to rotate, thereby driving the reversing plate 504 to rotate, thereby driving the protective idler roller connecting strip 802 to rotate, thereby driving the protective idler roller positioning plate 801 to rotate, thereby driving the protective idler roller 8 to rotate, so that the side idler roller 5 and the protective idler roller connecting strip 802 are perpendicular. At this time, due to the rotation of the reversing plate 504, the side idler roller positioning plate 5 can be made perpendicular to the protective idler roller connecting strip 802. 02 rotates, causing the side roller 5 to rotate. At this time, due to the action of the main buckle 507 and the secondary buckle 508 connecting the side roller, the bottom roller 501 rotates accordingly. Simultaneously, due to the action of the secondary buckle 509 and the main buckle 510 connecting the bottom roller, the angles of the two bottom roller positioning plates 503 can be changed, thus ensuring that the angle of the groove is variable. Furthermore, the action of the side roller spring 505 and the bottom roller spring 506 ensures the stability of the entire device. Further, the operator installs the belt 101 on top of the bottom roller 501. At this time, the belt 101 can be monitored by the camera 306. At this position, the belt 101 controls the adapter motor 403 to work, thereby driving each pressure roller 602 to be parallel to its bottom side roller 5 and bottom roller 501, thus ensuring the accuracy of belt pressing. Furthermore, the belt 101 controls the extension of the pressure rod 6, thereby driving the pressure roller 602 to move downwards, making the pressure roller 602 tightly against the belt 101 and applying force to the belt 101. At this time, the pressure sensor 402 monitors the pressure applied by the pressure roller 602, thus ensuring that the belt 101 is tightly against the side roller 5 and bottom roller 501 while preventing the belt 101 from being subjected to pressure according to the weight of the material. Furthermore, when the material moves to the bottom of the support frame 2, the belt 101 controls the reversing motor 305 to work, thereby driving the reversing main gear 304 to rotate, thereby driving the reversing secondary gear 303 to rotate, thereby driving the reversing rod 302 to rotate, thereby driving the reversing block 3 to rotate, thereby driving the positioning frame 4 to rotate, so that the pressure rod 6 rotates around the reversing rod 302, thereby facilitating material transportation. Furthermore, when the material passes the support frame 2, the belt 101 controls the reversing motor 305 to make the pressure wheel 602 close to the belt 101 again, thereby achieving belt pressing again, thus ensuring the stability of material transportation.
