By setting the sponge pad 102, it can prevent the gravel from directly hitting the baffle 101, causing wear to the baffle 101 and reducing the service life of the device. At the same time, it can provide a certain buffer for the gravel and avoid the collision of the gravel with the baffle 101 to produce sparks and cause explosions inside the mine. At the same time, the support spring 106 can provide a second buffer for the descending baffle 101.

[0026] like Figures 1 to 4 As shown, the main body mechanism 2 includes a main shell 201, a display screen 202 is arranged on the main shell 201, two fixing flanges 203 are fixedly connected to both sides of the main shell 201, a switch button 204 is arranged at the bottom of the main shell 201, a plurality of wiring ports 205 are fixedly connected to the top and bottom of the main shell 201, an indicator light 206 is fixedly connected to the bottom of the main shell 201, and a signal receiver 207 is fixedly connected to the top of the main shell 201.
