DEVICE FOR SAMPLING OF BULK MATERIALS

摘要

The device is used in metallurgy and other industrial sectors for sampling of bulk materials, mainly fine-grained ones. It improves the reliability and the representation of the samples and reduces costs. The sampling device includes a lead screw connected in its upper part to a drive fitted onto a plate to which a friction mechanisms is attached interacting with a disk and coaxially mounted rod and tube. Along the rod and the tube axis, along a spiral with the same pitch, stanted and open pockets are formed having a width equal to a half of the pitch of spiral, and the bases of the diametrically pleced pockets are formed along the radius. Pouring the material out of the pockets is effected from the inclination of the pockets to the axis at an angle of 40 to 60 .
