Abstract

Изобретение относитс к строительству . Цель - повьшение произв-сти бурени за счет автоматического управлени выгрузкой грунта из ковшового бура. На стреле базовой машины подвешены электропривод 2, установленный в кожухе 3 с возможностью осе-. вого перемещени , св занный с ковшовым буром 4, и стабилизатор. Ковшовый бур 4 имеет крышку 8, днице 9 и механизм разгрузки.Последний выполнен из установленных на крьш1ке 8 рычага, соединенной с ним посредством т ги 12, подпружиненной с двух сторон траверсы 1I и закрепленного в ней фиксатора 15 с наконечником, пропущенным через ковш бура. Днище 9 установлено одним концом шарнирно и выполнено на другом конце с пазом,в котором размещен наконечник фиксатора 15. Кожух 3 имеет неподвижный упор 16, а стабипи- затор выполнен в виде направл ющей стойки. Дл выгрузки грунта из бура 4 ему придают вращение. Рычаг набегает на упор 16 и отклон етс . Траверса 11 поворачиваетс вместе с фиксатором 15 до совмещени его наконечника с пазом в днице 9 и вывода из го. Днище 9 открываетс и грунт из бура выпадает. 5 ил. (б (ЛThe invention relates to construction. The goal is to increase drilling performance by automatically controlling the unloading of soil from a bucket drill. On the boom of the base machine are suspended electric drive 2, mounted in the casing 3 with the possibility of axle. displacement associated with a bucket drill 4, and a stabilizer. The bucket drill 4 has a lid 8, a flange 9 and a unloading mechanism. The latter is made of a lever 8 mounted on the grinder 8 connected to it by means of a pull 12, traverse 1I spring-loaded on both sides and a fixture 15 fixed in it with a tip passed through a drill bucket. The bottom 9 is pivotally mounted at one end and made at the other end with a groove in which the tip of the retainer 15 is placed. The casing 3 has a fixed stop 16, and the stabilizer is designed as a guide post. For unloading soil from auger 4, rotation is attached to it. The lever hits the support 16 and is deflected. The yoke 11 is rotated together with the latch 15 until its tip is aligned with the groove in the flank 9 and removed from the go. The bottom 9 opens and the ground from the drill falls out. 5 il.

Claims

Claim

Installation for drilling wells, including the base machine, on the boom of which is suspended an electric drive mounted in a casing with the possibility of axial movement and connected with a bucket drill having a lid and a bottom, a stabilizer for moving the casing, characterized in that, in order to increase drilling performance due to automatic control of the unloading of soil from the bucket drill, the latter is equipped with an unloading mechanism, and the casing is equipped with a fixed stop located at the lower end, while the bucket drill unloading mechanism is made and h of a lever mounted on the cover of the bucket auger, from a beam connected to it by a rod spring-loaded on both sides and from a latch fixed to it with a tip, passed through the bucket, the bottom of the bucket auger is pivotally mounted at one end and grooved at the other end, in which the clamp tip is placed with the possibility of withdrawing it from the groove when the lever interacts with the casing stop, while the stabilizer is made in the form of a guide rack.
