Technical Problem

[0003]然而现有的检测装置采用顶部监控的方式，来观察溜槽的堵塞状态，但向下倾斜监控的观察方式，位置较为固定，容易出现检测上的失误；

Benefits of technology

[0017] 1. This utility model utilizes the planar structure on the outer wall of the chute box, with a wear-resistant glass plate embedded for isolation, and through-beam photoelectric sensors and multiple sets of light receivers set on both sides respectively. The laser of the through-beam photoelectric sensor passes through the detection area inside the chute box and the receiver receives it normally. When the sensor descends to a certain position and the detected object blocks the laser, the sensor signal changes abruptly. This signal is immediately sent to the PLC. The PLC responds within milliseconds and immediately cuts off the "pulse" sent to the servo driver or outputs an "emergency stop" signal.
