Description
ii
Изобр етение относитс к бурению, а именно к устройствам дл отбора проб при геологических изыскани х дорог, водных переправ, jmmt эйектропередач , объектов промышленного и гражданского проектировани .The invention relates to drilling, in particular, to devices for sampling in geological surveys of roads, water crossings, jmmt eject transmissions, industrial and civil engineering objects.
Известно устройство дл отбора проб грунта из стенок скважины при шнековом бурении, включающее шнековую колонну и пробоприемник в виде двух шарнирных крышек, закрепленных на лопаст х шнека l .A device for sampling soil from the borehole walls during auger drilling is known, which includes an auger column and a sample receiver in the form of two hinged caps attached to the blade x of the auger l.
Недостатком данного устройства вл етс малый объем отбираемой пробы.The disadvantage of this device is a small sample volume.
Известно также устройство дл отбора проб грунта из стенок скважиНЫ , включающее полую шнековую колонну и пробоприемник, расположенный в чинековой колонне и перекрытый шарнирно закрепленной крьпнкой 2.It is also known a device for sampling soil from the walls of a well, comprising a hollow auger column and a sample receiver, located in a chine column and covered with a hinged arm 2.
Недостатком данного устройства вл етс то, что при подъеме устройства не исключена возможность проворота его против часовой стрелки. Б результате может самопроизвольно раскрытьс пробоприем шк и высыпатьс часть пробы. Все это снижает надежность работы устройства.The disadvantage of this device is that when lifting the device it is not possible to turn it counterclockwise. As a result, the sample can be spontaneously opened and the part of the sample is poured out. All this reduces the reliability of the device.
Целью изобретени вл етс повышение надежности работы устройства.The aim of the invention is to improve the reliability of the device.
Указанна цель достигаетс тем, что пробоприемник выполнен в виде полуцилиндра с режущей кромкой, а This goal is achieved by the fact that the sample receiver is made in the form of a half cylinder with a cutting edge, and
10 крьшгка -в виде двуплечего рычага, причем шарнир крышки расположен по оси полуцилиндра.10 bolt -in the form of two shoulders of the lever, with the hinge of the cover is located along the axis of the half-cylinder.
На фиг.1 схематически изображено предлагаемое устройство, общий вид; In Fig.1 schematically shows the proposed device, a General view;
(S на фиг.2 - разрез А-А на фигу.(S in FIG. 2 - section A-A in FIG.
