The mounting groove is conveniently connected with a connector so that multiple support plates 01 can be connected. The friction sleeve increases friction to ensure the transportation of the belt.

[0042] The implementation principle of the embodiment of the present application is:

[0043] During transportation, the support plate 01 and guide strip 05 of corresponding curvature are selected as needed, and the corresponding assembly is performed. At the same time, according to the specific settings, the sliding block 21 is moved and the length of the hydraulic cylinder 4 18 is adjusted, so that the lower limit frames 04 on both sides have corresponding tilt angles to ensure the set transportation needs. Then, according to the settings, the heights of the hydraulic cylinders 3 15 and 1 07 are adjusted, and the corresponding settings are performed. Then, the hydraulic cylinder 2 09 is adjusted to make the flat plate 3 11 descend and tilt, so that the inclined plate 14 and the belt roller 02 are parallel to each other and reach the corresponding distance, thereby realizing the early adjustment.

[0044] During operation, external power is provided to rotate the power shaft 19 and the belt roller 02, thereby causing the belt to move. During the movement, real-time monitoring is performed based on the video of the camera 25. After the belt is displaced, the hydraulic cylinder 2 09 and the hydraulic cylinder 3 15 on the displacement side are adjusted through the background to move the flat plate 3 11. The operation can be performed multiple times, and the friction force is used to push the belt back. At the same time, the hydraulic cylinder 4 18 can also be used for fine-tuning to offset the center of gravity of the belt, thereby automatically returning to its original position.

[0045] When the belt is curling, the hydraulic cylinder 209 can be adjusted to deflect the angle of the flat plate 311, and the telescopic rod 234 can be controlled to extend or retract, thereby driving the contact roller 33 to enter the edge of the curling to disturb it. At the same time, the hydraulic cylinder 418 can be fine-tuned to push the curling back into place, reducing the operation of subsequent personnel.

[0046] When the minerals fall from one side of the belt due to their own centrifugal effect, the hydraulic cylinder 18 can be adjusted to change the angles of the upper limit frame 03 and the lower limit frame 04 relative to the support plate 01, so that the minerals stop falling under the action of gravity and friction and return to the center of the belt.

[0047] During the upper adjustment process, the motor 30 can work synchronously as needed, thereby driving the upper device to move synchronously, and then driving the movement of the executing device to meet the needs of the work.

[0048] During the overall operation, the power shaft 19 rotates to drive the transmission assembly 35 to rotate, and then through the transmission of the gearbox 29, the rotating roller 22 rotates, and further the telescopic rod 24 and the impact ball 23 rotate, and the impact ball 23 hits the upper limiting frame 03, causing the power shaft 19 and the belt roller 02 to vibrate, and then the belt produces corresponding vibrations. Under the action of gravity and vibration, the minerals gather toward the center of the belt, thereby further preventing the minerals from falling, and the vibration can return the belt to its original position, further reducing the probability of its deviation.

[0049] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention.
