[0020] Embodiment 1: Please refer to Figures 1-3, A dual-probe speed measurement device for belt scales, including a belt conveyor 1. The belt conveyor 1 includes a crossbeam 11 and an L-shaped fixed plate 12 installed between the crossbeams 11. A detection plate 14 is installed at the bottom end of the L-shaped fixed plate 12. A roller 15 is installed inside the detection plate 14, and a detection component 13 is installed outside the detection plate 14.

[0021] The detection component 13 includes an installation frame 131 and a detection hole 132 opened on the outer wall of the installation frame 131. A T-shaped insertion rod 1314 is installed inside the detection hole 132. A rubber ring 1316 is installed through the middle of the T-shaped insertion rod 1314. An infrared photoelectric sensor 1311 is inserted inside the rubber ring 1316, and the infrared photoelectric sensor 1311 is used to measure the speed of the belt conveyor 1.

[0022] A rubber cylinder 1315 is installed on the inner wall of the installation frame 131 and outside the detection hole 132. A positioning insertion rod 1317 is installed on the outside of the T-shaped insertion rod 1314. The infrared photoelectric sensor 1311 is inserted into the inside of the rubber ring 1316, and the positioning insertion rod 1317 is inserted into the inside of the rubber cylinder 1315 to fix the positions of the T-shaped insertion rod 1314 and the infrared photoelectric sensor 1311.

[0023] A rotating groove 133 is opened at the upper end of the outside of the installation frame 131. A rotating plate 134 is installed by hinge inside the rotating groove 133. A buzzer 1313 and a single-chip microcomputer 1312 are installed inside the installation frame 131. A warning light 1341 is installed on the outside of the rotating plate 134. The infrared photoelectric sensor 1311, the single-chip microcomputer 1312, the buzzer 1313, and the warning light 1341 are electrically connected.

[0024] A slot 135 is penetrated and opened at the lower end of the outside of the rotating plate 134 and below the warning light 1341. A dust-proof net 136 is installed inside the slot 135. After the infrared photoelectric sensor 1311 detects an abnormality, the single-chip microcomputer 1312 controls the buzzer 1313 to operate, and the generated sound can be transmitted through the dust-proof net 136.

[0025] A threaded hole 137 is opened at the lower front side of the installation frame 131. A bolt 138 is threadedly connected to the lower end of the rotating plate 134, and the threaded end of the bolt 138 is threadedly connected inside the threaded hole 137 to install the rotating plate 134 and the installation frame 131.

[0026] There are two sets of detection components 13, and the two sets of detection components 13 are installed outside the roller 15. Two sets of detection components 13 are set to measure the speed of the belt conveyor 1. When one set of detection components 13 is damaged, the other set of detection components 13 can continue to measure the speed of the belt conveyor 1.

[0027] In this embodiment: The infrared photoelectric sensor 1311 detects the rotation speed of the roller 15. The single-chip microcomputer 1312 detects the data detected by the infrared photoelectric sensor 1311. When the rotation speed of the infrared photoelectric sensor 1311 is abnormal, the single-chip microcomputer 1312 controls the buzzer 1313 and the indicator light 1341 to operate. The buzzer 1313 makes a sound to remind the operator through the dust-proof net 136 that the detection component 13 is damaged. The light generated by the indicator light 1341 facilitates the operator to identify that the detection component 13 in the two groups is damaged. When one group of detection components 13 is damaged, the other group of detection components 13 measures the speed of the belt conveyor 1, and the damaged detection component 13 can be repaired. Rotate the bolt 138, and the threaded end of the bolt 138 turns out of the inside of the threaded hole 137. The rotating plate 134 can be rotated. Put your hand into the inside of the mounting frame 131, hold the infrared photoelectric sensor 1311 and the T-shaped insertion rod 1314. The positioning insertion rod 1317 is pulled out of the inside of the rubber cylinder 1315, and the T-shaped insertion rod 1314 is pulled out of the inside of the detection hole 132, which facilitates the extraction of the infrared photoelectric sensor 1311 from the inside of the detection hole 132 to repair the damaged infrared photoelectric sensor 1311. After the repair is completed, the T-shaped insertion rod 1314 is inserted into the inside of the detection hole 132, and the positioning insertion rod 1317 is inserted into the inside of the rubber cylinder 1315 to fix the position of the T-shaped insertion rod 1314. The detection end of the infrared photoelectric sensor 1311 is inserted into the inside of the rubber ring 1316 to fix the position of the infrared photoelectric sensor 1311.

[0028] Working principle: Two groups of detection components 13 are installed in the belt conveyor 1 to reduce the on-line failure rate of the belt weigher. By installing two groups of detection components 13 in the same set of belt weigher system, when a single detection component 13 is damaged, it will not affect the metering accuracy of the belt weigher and prevent the occurrence of metering accidents. When the rotation speed of the infrared photoelectric sensor 1311 is abnormal, the single-chip microcomputer 1312 controls the buzzer 1313 and the indicator light 1341 to operate. The buzzer 1313 makes a sound to remind the operator through the dust-proof net 136 that the detection component 13 is damaged. The light generated by the indicator light 1341 facilitates the operator to identify that the detection component 13 in the two groups is damaged. When one group of detection components 13 is damaged, the other group of detection components 13 measures the speed of the belt conveyor 1, and the damaged detection component 13 can be repaired.
