Coal furnace sampling auxiliary device

The utility model relates to a sampling auxiliary device of a coal charging furnace, the existing sampling auxiliary device of the coal charging furnace can only adopt one coal sample, the later research on the coal quality is inconvenient due to fewer samples, and the following scheme is put forward: the sampling auxiliary device comprises a support plate, a drill rod, a sampling groove, a protective cover, a roller, a strap and an L-shaped handle, two sets of arc-shaped hooks are installed at the left end and the right end of the front side of the supporting plate, a servo motor is fixedly installed in the middle of the upper surface of the supporting plate, a drill rod is installed in the middle of the lower surface of the supporting plate, and the rotating shaft end of the servo motorpenetrates through the supporting plate and extends to the top end of the drill rod to be fixedly connected. And a plurality of groups of sampling grooves are uniformly distributed in the middle of the drill rod. According to
