[0014] 1. The utility model is provided with a first spring, a second spring, a first hydraulic damper, a second hydraulic damper and a buffer pad. When an object falls from the top of the mining machinery, the fallen object falls on the protective frame, the protective frame moves downward, and the protective frame pushes the vertical rod to slide downward, squeezing the first spring and the first hydraulic damper, thereby playing a first-level buffering and protective role. When the pressure is too large, the buffer pad falls on the top of the mining machinery to protect the top of the mining machinery.
