DEVICE FOR SAMPLING OF MILLED PEAT Russian patent published in 1998 - IPC

FIELD: devices for mechanized sampling of hard loose materials, in particular, devices for testing the quality of milled peat, bituminous coal, grains. SUBSTANCE: device includes guide frame, sampler for taking samples from railroad cars, drive and control panel. Device is provided with path-control transducers. The first transducer of the first pair is installed with front end of gondola car spaced from axis of guide frame through 1/8-1/10 of its length. The first transducer of the second pair is installed with the middle of gondola car coinciding with frame axis. The first transducer of the third pair is installed at approach of rear end of gondola car to axis of guide frame for 1/8-1/10 of its length. The second transducers of every pair are spaced from the first transducers at a distance equalling the distance between axles of outer (inner) front and rear wheel of gondola car. Transducers in each pair are interconnected in series and electrically connected with drive and control panel. EFFECT: reduced expenditures for testing materials due to mechanized sampling and less fatigue of operator. 6 dwg
