[0002] In the field of unmanned operation, the fully automatic reclaimer not only saves the labor intensity of the reclaimer driver, but also simplifies the operation difficulty of the reclaimer and improves the working efficiency of the reclaimer. The fully automatic reclaimer mainly uses a 3D laser scanner to scan the material pile in real time, obtains the actual data of the material yard, and combines the positioning data to generate a three-dimensional model of the material pile and the posture information of the bucket wheel stacker and reclaimer. Through a series of algorithm processing and extraction, it guides the stacker and reclaimer to complete unmanned operation. When working, the arm of the fully automatic reclaimer can rotate 360°. The arm is fixed on the rotary trolley through a steel structure. The arm is rotated when the rotary trolley runs along the rotary track. The fully automatic reclaimer has a belt hanging on the arm. Due to the deviation of the belt and other conditions, the material is spilled and accumulated on the rotary track, which poses a huge risk to the large machine. At present, there is no reliable detection method for whether there are scattered materials and foreign objects on the rotating track of the fully automatic reclaimer during operation, because if there are foreign objects on the rotating track, there will be collisions, causing the rotating trolley to derail and crack the steel structure, and other very serious consequences, and even the overturning of the entire machine. Therefore, it is necessary to design a rotating track protection device to detect whether there are foreign objects when the fully automatic reclaimer is rotating. Utility Model Content
