[0040] The mounting seat 7 is slidably arranged on the upper part of the main body of the oscillation shaft 1, and the mounting seat 7 is locked in position by means of an adjusting bolt 8.

[0052] The present invention can perform aggregate analysis on two or more soil samples simultaneously. The number of soil samples can be adjusted according to demand by adjusting the corresponding number of cantilevers. The cantilevers are easy to install, and the cantilevers can be evenly controlled in angle by connecting rods. The number of groups of soil samples can be two, three, four, five, etc.
