METHOD OF AND APPARATUS FOR MEASURING MINING DEPTH OF A DEPOSIT BEING MINED BY A DEEP-DIGGING EXCAFATOR

摘要

1. The invention concerns a device for measurement of depth of mined deposit by deep-scooping engine equipped with hoisting line winch, on whose drum is wound line with elimination of slackness, with scoop suspended on this line, in said device is potentiometric converter levelling measurement unit, characterised in that gear wheel (3) of drum's (2) drive of hoisting winch is in gear via intermediate gear wheel (4) with worm gear (5), whereas worm wheel's shaft is coupled via axially set clutch with toroidal potentiometer's shaft (6), and output of potentiometer (6) is connected to input of current transistor amplifier, to whose output are connected measurement or recording devices.IMAGE
