Integrated sieve device for particle size screening of soil samples

An integrated sieve device for particle size screening of a soil sample, the integrated sieve device comprising:

• a particle size screening unit having at least one sieve and configured to screen the soil sample by particle sizes and to drop the soil sample;
• a body housing in a cylindrical shape, wherein a part of a lateral surface of the body housing is open, wherein the particle size screening unit is detachably coupled to an inner lateral surface of the body housing in a direction that the part of the lateral surface of the body housing is open,
• wherein a pair of convex portions are formed on an inside of the lateral surface of the body housing,
• wherein a pair of groove portions are formed on an outside of a lateral surface of the particle size screening unit, and
• wherein the pair of convex portions are respectively coupled to the pair of groove portions such that the particle size screening unit is pivotable in a predetermined angle;
• a sample reception unit mounted at a lower portion of the particle size screening unit coupled to the body housing and configured to collect soil and water discharged below the particle size screening unit by being screened by the sieve;
• and
• a water supply unit mounted at an inlet formed on an upper end of the body housing and configured to supply water into the particle size screening unit.
