The working principle of the invention is as follows:
conveying artificial sandstone with the sand making granularity of 0-5mm into a feeding port 12 of a distributing device 11, wherein the distributing device 11 is obliquely communicated with a feeding port 7, so that sandstone materials fall on an uppermost-stage scattering block 13 of the distributing device 11, the scattering block 13 is in an oblique triangular prism structure and scatters and distributes the materials on two sides of the scattering block 13, the materials obliquely fall onto the scattering block 13 of the next stage along with gravity, the materials are continuously scattered by adjacent scattering plates which are distributed on two sides of the upper-stage scattering plate, and the feeding port 12 can be in a bucket shape to ensure that the uppermost-stage scattering block 13 is scattered and uniformly dispersed step by step;
from the feeding port 12 to the direction of the feeding port 7 of the V-shaped selecting device 2, the number of the scattering blocks 13 at each stage is increased step by step, the size of the scattering blocks 13 at each stage is reduced step by step, the structure is compact, the space is reasonably utilized, the materials are scattered step by step and form a uniform material curtain under the material distributing effect, and the V-shaped reinforcing ribs 14 play a role in enhancing the structural strength of the inner wall of the material distributing device 11 where the scattering blocks 13 are located, so that the material distributing effect is prevented from being influenced by impact deformation;
therefore, materials are pre-separated and fully scattered to enter the feed inlet 7 of the V-type separation device 2 through unpowered scattering and distribution, the problems that due to the fact that the phenomenon of agglomeration is caused, feeding is uneven and the classification efficiency of the powder concentrator is low are solved, air is blown to the air inlet of the V-type separation device 2 through the fan 1, the second driving mechanism 24 enables the rocker arm 242 to be separated from the scale limiting block 243 by loosening the second positioning bolt 27, and the deflection rocker arm 242 drives the deflection plate to deflect synchronously through the second support shaft 241;

materials entering the V-shaped sorting device 2 from the feeding hole 7 are further scattered layer by layer under the action of two groups of first fixed scattering blades 9 and second fixed scattering blades 10 which are inclined oppositely, sand with different grain diameters generates different falling speeds in the falling process, so that relative friction is generated between sand grains for a plurality of times so as to strip mud powder and stone powder on the surfaces of the sand grains, and discharged materials and fine materials in material flows are blown away under the action of wind power;
the telescopic blade 16 parallel to the side of the second fixed scattering blade 10 is supported on the V selecting device 2 through the first supporting shaft 181, the first positioning bolt 20 is loosened, the sliding handle 182 is pulled to enable the sliding hole 19 of the V selecting device 2 of the first supporting shaft 181 to move to change the position of the telescopic blade 16, then the first positioning bolt 20 penetrates through the sliding handle 182 to be positioned and locked with the V selecting device 2, the first driving mechanism 18 drives the telescopic blade 16 to move back and forth on the V selecting device 2 in parallel to the second fixed scattering blade 10, and the total length of the telescopic changed and second fixed scattering blade 10 is formed;
