The sieving instrument comprises a base plate, an elastic vibration module, an upright column, a frame beam, a vibration table mounted on the elastic vibration module, and the sieve box is arranged on the vibration table; the elastic vibration module, the upright column and the frame beam are mounted on the base plate; a feeding box is fixedly mounted at the upper part of the frame beam, and an outlet of the feeding box extends into the sieve box; carrying platform are mounted on the upright column, a plurality of storage boxes are arranged on the carrying platform; the sieve box is divided into a plurality of grids from bottom to top by a plurality of sieve pore plates arranged horizontally, and one storage box is correspondingly arranged at the discharge port of each grid, and the discharge port of each grid is aligned with the feeding port of the corresponding storage box; and the vibration table tilts on one side. The sieving instrument is quick and convenient to use, and reliable in accuracy.
