The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0018] See also Figures 1 to 3The utility model provides an automated belt conveyor system for a shield machine, the automated belt conveyor system for a shield machine comprising a belt frame, a conveying belt 101, a driven wheel bracket 102, a driven wheel rotating mechanism, a lifting beam 103, a deviation detection device 104, a driving device 105, a tensioning cylinder 106 and a belt frame tilting mechanism.

[0019] The lifting beam 103 is installed on the belt rack, and an industrial camera 111 is provided on the lifting beam 103. The belt rack is also provided with multiple deviation detection devices 104. The belt rack is also provided with a laser scanner 112, a weighing sensor 113, a tension sensor 114 and a speed sensor 115. The laser scanner 112, the weighing sensor 113, the tension sensor 114 and the speed sensor 115 are all installed on the end of the belt rack close to the driving frame 108. The belt rack is also provided with the belt rack tilting mechanism.

[0020] In this embodiment, the tension sensor 114 is used to detect the tension of the conveyor belt 101 in real time, and the tensioning cylinder 106 is started to adjust the position of the drive frame 108 to complete the adjustment of the tension of the conveyor belt 101. Through the setting of the industrial camera 111, the appearance characteristics of the slag such as temperature, color, particle size and shape are collected. Combined with image processing technology, the system can identify the type of slag (such as sand, clay, hard soil, etc.). The automatic monitoring and control system automatically adjusts the speed and tension of the conveyor belt according to the data recognized by the sensor, and detects the deviation of the slag through the deviation detection device 10 4. The driven wheel rotation mechanism and the belt frame tilting mechanism are configured to adjust the steering angle of the driven wheel 110 and the tilting angle of the belt frame to prevent the slag from overflowing from the belt conveyor. The weighing sensor 113 is configured to realize real-time monitoring of the slag weight. The laser scanner 112 is configured to collect the three-dimensional contour data of the slag in real time and quickly calculate the volume. Finally, the system fuses the data of the weighing sensor 113 and the volume detection sensor to calculate the weight of the slag per unit volume. The above structure can automatically monitor and control the belt conveyor and improve the conveying efficiency and stability.

[0021] Furthermore, the driven wheel rotation mechanism includes a mounting bearing 116, a rotating pin 117, a steering angle sensor 118 and a steering cylinder 119. The mounting bearing 116 is provided inside the base of the driven wheel bracket 102. The rotating pin 117 is assembled inside the mounting bearing 116 and is reliably connected to the belt rack. The steering angle sensor 118 is installed on the driven wheel bracket 102. The mounting end of the steering cylinder 119 is connected to the belt rack, and the output end of the steering cylinder 119 is connected to the driven wheel bracket 102.

[0022] In this embodiment, since the driven wheel bracket 102 and the belt frame are connected by a pin shaft, when the rotating cylinder is started, the driven wheel bracket 102 can be driven to rotate on the belt frame, thereby adjusting the steering angle of the driven wheel 110, and through the setting of the steering angle sensor 118, the steering angle of the driven wheel bracket 102 is adjusted, so that the adjustment accuracy is higher.

[0023] Furthermore, the belt frame tilting mechanism includes a tilting cylinder 120 and a tilting angle sensor 121, the belt frame includes a mounting base 122 and a belt frame body 123, the belt frame body 123 is rotatably mounted on the top of the mounting base 122 through a rotating shaft 124, the tilting angle sensor 121 is provided on the mounting base 122, and the output end of the tilting cylinder 120 is connected to the belt frame body 123.

[0024] In this embodiment, the tilt cylinder 120 is started, and the belt frame body 123 is rotated on the mounting base 122 through the rotating shaft 124, thereby completing the adjustment of the angle of the belt frame body 123. The tilt angle is monitored by the setting of the tilt angle sensor 121, so that the adjustment accuracy is higher.

[0025] Furthermore, rollers 125 are provided on both sides of the top and bottom ends of the belt frame body 123. The two rollers 125 are respectively located on both sides of the conveyor belt 101. Each roller 125 is provided with a deflection wheel 126 at one end away from the conveyor belt 101.

[0026] In this embodiment, by setting the roller 125, since the roller 125 adopts a rolling friction method, the conveyor belt 101 rolls on the roller 125 instead of directly contacting the belt frame, thereby greatly reducing friction, reducing energy consumption, and extending the service life of the conveyor belt 101. By setting the deflection wheel 126, when the conveyor belt 101 deviates during the conveying process, the deflection wheel 126 can rotate itself to forcibly correct the conveyor belt 101 and return it to the correct running track.

[0027] Furthermore, a sliding guide rail 127 is provided at one end of the belt frame away from the screw conveyor 107 , and the bottom of the driving frame 108 is connected to the sliding guide rail 127 via a pulley 128 .

[0028] In this embodiment, the position of the driving frame 108 is adjusted by cooperating with the sliding guide rail 127 and the pulley 128 , thereby adjusting the tension of the conveyor belt 101 .
