When the rolling ball 334 rotates, the weighing trough 335 rotates the powder inside. At the same time, other parts of the rolling ball 334 block the conical hole 332 to prevent the powder inside the conical hole 332 from falling. When the weighing trough 335 filled with powder reaches the discharge nozzle 336, it is discharged, and the number of times the pressing block 339 is pressed is selected according to the weight of the required sampling to realize rapid quantitative sampling and improve the sampling efficiency of the device.
