FIELD: testing engineering.
SUBSTANCE: device comprises cell and drive provided with crank mechanism. The cell is made of the adjustable faces that are inclined at an angle larger than the natural slope of the material that fills the cell, controlled sloping walls, bottom made of a support, and pivots for controlled sloping sides. The sloping side of the cell is spring-loaded. The cell has a bellows made of corrugations that tightly connects the controlled face and sloping side. The cell is mounted in the housing that has sides and base made in block with the base of the cell.
EFFECT: enhanced reliability and efficiency.
