In this way, the waste rock conveyed by the waste throwing belt falls onto the sampling plate 22 for primary sampling work. After completion, the sampling plate 22 can be lifted to send the material from the second discharge port 27 to the crushing device, or it can be rotated downward to send the material from the first discharge port 15 to the waste rock bin. When the cylinder 39 in the driving component 3 of the present utility model works, it drives the power shaft 35 to rotate through the power rod 36, and then applies a rotational force to the main shaft 21 on the sampling component 2. When the main shaft 21 rotates clockwise, the end of the sampling plate 22 is lifted, and the waste rock on the sampling plate 22 falls from the second discharge port 27 onto the conveyor belt of the crushing device along the guide plate 23 for the crushing and sizing process. When the main shaft 21 rotates counterclockwise, the end of the sampling plate 22 turns downward, so that the waste rock on the sampling plate 22 directly falls into the waste rock bin from the first discharge port 15. Automatic control is implemented through the cylinder 39 to achieve automatic and regular sampling, which is more practical.
