Sample preparation device for preparing small quartz sand sample from quartz ore

The utility model relates to the field of physical analysis, in particular to a sample preparation device for preparing small sample quartz sand from quartz ore, which comprises a groove body and a knocking rod, the groove body is made of tungsten-molybdenum alloy, the outer bottom of the groove body is round, the opening of the groove body is round, the knocking rod is made of tungsten-molybdenum alloy, the rod body is cylindrical, and the outer bottom of the groove body is round. The diameter of the cylinder at the upper end of the knocking rod is increased, and the knocking surface at the lowermost end of the knocking rod is semicircular. The sample preparation device has the advantages that the tank body and the knocking bar of the sampler for chemical analysis of the quartz ore are made of the tungsten-molybdenum alloy, the hardness of the tungsten-molybdenum alloy is greater than 7, other pollution to the quartz sand during preparation of the quartz sand is avoided when the quartz ore is knocked, and th
