Abstract:
To disclose polishing and separation equipment for an agricultural land soil sample.SOLUTION: Polishing and separation equipment for an agricultural land soil sample of the present invention comprises: a polishing box; a rough polishing space that opens upward is provided in the polishing box; and a soil crushing device is provided in the rough polishing space. The soil crushing device can agitate and crush the soil sample. The polishing and separation equipment of the present invention can swiftly initially agitate and crush the soil sample by an agitation-vibration-separation device, and simultaneously vibrating and crushing the soil sample, thus can remove impurities such as plant rhizomes and stones included in the sample, to thereby prevent the impurities from affecting analysis, and to enhance measurement results. A compression rough polishing device utilizes a double compression rod mechanism, and one compression rod is always in an operating state, to thereby allow rough polishing to be performed in a continuously compressed state, and thus efficiency of the rough polishing is improved.SELECTED DRAWING: Figure 1
