Detailed Description

The utility model will be further described with reference to the accompanying drawings.

The utility model provides a laboratory soil detects with multistage screening drying device, includes box 1, box 1 upper end is provided with import hopper 2, box 1 lower extreme is provided with export hopper 3, import hopper 2 with be screening drying zone 4 between the export hopper 3, it has screening mechanism 5 that a plurality of slopes set up to distribute step by step along the blanking direction in the screening drying zone 4, a plurality of screening mechanism 5 end to end, and the junction transition department all is provided with breaks mechanism 6, a plurality of screening granularity level of screening mechanism 5 progressively decreases progressively along the blanking direction and sets up, is located the end screening mechanism 5 tail end is provided with filter residue export 7, a plurality of drying mechanism 8 have evenly been laid to box 1 inner wall.
