DEVICE TO TAKE SAMPLES FROM DROPPING FLOW OF LOOSE MATERIAL Russian patent published in 1995 - IPC

FIELD: measurement technology. SUBSTANCE: device to take samples from dropping flow of loose material is provided with blades controlling flow of material put in cantilever at point of expansion of body on axles located in its upper part on opposite sides. Blades are mounted for synchronous turning in vertical plane from one extreme position to another. Blades are fitted with drive. Sampler is made fast in body. Take-in slot of sampler is positioned below lower ends of blades perpendicular to plane of their turning to take samples from entire plane of section of flow of material dropping and moved with blades. Sampler is equipped with dividing damper. Hole to remove excess of sample of material into space of body is located at level of position of damper. Blades are mounted in parallel to each other and have length not less than length of take-in slot of sampler. In extreme positions one of blades is arranged in parallel to inner wall of body in close vicinity from it. EFFECT: expanded application field, simplified design. 3 cl, 2 dwg
