[0026] As shown in the drawings: Figure 1 to the drawings: Figure 3 As shown in the drawings: cross beam 501 is fixedly arranged on rack 1, provides support for entire adjustable supporting roller assembly 5, and sliding slot is formed in both ends thereof, sliding seat 5043 is slidably arranged in sliding slot, sliding seat 5043 is guided and limited by sliding slot, to ensure the moving stability of sliding seat 5043. Cross roller 502 is rotatably arranged on cross beam 501, for supporting the middle part of conveying belt 4, to ensure the stable operation of conveying belt 4.

[0027] As shown in the drawings: Figure 2 to the drawings: Figure 3As shown in the drawings: the inclined roller unit 503 includes an inclined roller 5031, both ends of the inclined roller 5031 are provided with hinged seats 5032, both ends of the hinged seat 5032 are respectively hinged with a hinged plate 5033 and a connecting plate 5034, and a movable gap is reserved at the hinge to avoid the impression of jamming during movement. The inclined roller 5031 is used to support both sides of the transmission belt 4 to prevent the transmission belt 4 from deviating. The adjusting unit 504 is composed of an electromagnetic clutch 5041, a screw rod 5042, a sliding seat 5043 and a driving motor 5044. Two screw rods 5042 are respectively installed at both ends of the electromagnetic clutch 5041, the screw rod 5042 is threadedly sleeved with the sliding seat 5043, and the screw direction and pitch of the two screw rods 5042 are the same. The output end of the driving motor 5044 is in transmission connection with one of the screw rods 5042 for driving the screw rod 5042 to rotate. The sliding seat 5043 is hinged with the hinged plate 5033, the lower end of the connecting plate 5034 is fixed with the sliding seat 5043, and the driving motor 5044 drives the screw rod 5042 to rotate, so that the linear motion of the sliding seat 5043 can be realized, thereby adjusting the angle and position of the inclined roller 5031.

[0028] As shown in the drawings Figure 2 As shown in the drawings Figure 3 As shown in the drawings: the deviation detection module 6 adopts a Hall sensor installed near the inclined roller 5031 for detecting the angle change of the inclined roller 5031. When the transmission belt 4 deviates, the inclined roller 5031 will be subjected to a lateral force and rotate, and the Hall sensor detects the magnetic field change of the magnetic component installed on the inclined roller 5031, and outputs a corresponding electric signal, thereby realizing the detection of the deviation of the conveying belt.

[0029] As shown in the drawings Figure 2 Figure 3 As shown in the drawings: the load monitoring module 7 adopts a piezoresistive film sensor directly pasted on the stress surface of the bearing seat of the inclined roller 5031. When the inclined roller 5031 bears the coal load, the bearing seat deforms slightly, so that the resistance value of the film sensor changes, and the load borne by the roller can be known by measuring the change of the resistance value. The deviation detection module 6, the load monitoring module 7, the electromagnetic clutch 5041 and the driving motor 5044 are electrically connected with the control system of the belt conveyor. According to the detection signals of the deviation detection module 6 and the load monitoring module 7, the control system controls the combination and separation of the electromagnetic clutch 5041 and the operation of the driving motor 5044, so as to realize the intelligent adjustment of the angle and position of the inclined roller 5031.

[0030] Working principle:

[0031] The belt deviation automatic adjustment: during the operation of the belt conveyor, the Hall sensor of the deviation detection module 6 detects the angle change of the tilt roller 5031 in real time. When the belt deviates, the tilt roller 5031 is rotated by the lateral force, and the Hall sensor detects the magnetic field change and transmits the signal to the belt conveyor control system.

[0032] After the control system receives the deviation signal, the deviation direction and degree are analyzed, and the driving motor 5044 is controlled to rotate forward or reverse. The driving motor 5044 drives the screw rod 5042 to rotate through the transmission component, so that the sliding seat 5043 moves linearly, the hinged plate 5033 is pushed to drive the hinged seat 5302 to rotate, and the angle of the tilt roller 5031 is adjusted. For example, if the belt deviates to the right, the control system controls the driving motor 5044 to rotate forward, so that the right side of the tilt roller 5031 is lifted upward, a lateral force to the left is generated, the belt is pushed to move to the left, and the belt is restored to the normal operating position.

[0033] During the adjustment process, the deviation detection module 6 continuously monitors the running state of the belt and feeds back real-time data to the control system. When the belt is restored to the normal position, the control system stops the operation of the driving motor 5044, and the deviation adjustment is completed.

[0034] The load change automatic adaptation: the piezoresistive film sensor of the load monitoring module 7 monitors the stress condition of the bearing seat of the tilt roller 5031 in real time, converts the resistance value change into an electric signal, and transmits the electric signal to the control system. The control system calculates the load size of the current belt according to the change of the electric signal.

[0035] When the control system detects that the load increases, the control electromagnetic clutch 5041 is combined to make the two screw rods 5042 rotate synchronously. The driving motor 5044 drives the screw rod 5042 to rotate, so that the sliding seat 5043 moves outward, the distance between the tilt roller 5031 and the carrier roller is increased, the supporting force is improved, and the larger load is adapted. When the load decreases, the control system controls the electromagnetic clutch 5041 to separate, only one screw rod 5042 rotates, the sliding seat 5043 moves inward, the distance between the tilt roller 5031 and the carrier roller is reduced, and the running resistance is reduced. The load monitoring module 7 continuously monitors the load change and feeds back the data to the control system. The control system dynamically adjusts the position of the tilt roller 5031 according to the real-time load condition, so that the belt can stably run under different loads.

[0036] The embodiments of the utility model are given for example and description, although the embodiments of the utility model have been shown and described above, it is understood that the above-mentioned embodiments are exemplary, and cannot be understood as the limitation of the utility model, and the ordinary skilled person in the art can change, modify, replace and transform the above-mentioned embodiments within the scope of the utility model.
