Press such scheme, described sieving plate is fan-shaped, and the xsect of sieving plate is identical with the xsect of charge cask, the sieve aperture that gathers on sieving plate, sieve diameter >=4.75mm.
Press such scheme, described sieving plate is fan-shaped framework, by linear beam, Curved beam and column, forms sandwich construction, plug-in mounting screen cloth in interlayer, the sieve aperture that gathers on screen cloth, sieve diameter >=4.75mm.
Press such scheme, described sieving plate is four, is followed successively by from top to bottom the first sieving plate, the second sieving plate, the 3rd sieving plate, the 4th sieving plate, and described layering opening and arc opening are four.
Press such scheme, described water filling nozzle is conical nozzle.
Press such scheme, described sieving plate thickness is 1.5mm～2.5mm, and layering open height is 3.5mm～4.5mm.
The beneficial effects of the utility model are: a kind of pick-up unit of homogeneity of concrete is provided, by each layer of coarse aggregate quality after drying, has contrasted, weighed fresh concrete homogeneity; It is simple in structure, easy and simple to handle, sense cycle is short.
