Claims (11)

1. Вставка для удерживания с возможностью высвобождения режущего средства в земляном буре, содержащая цилиндрический элемент, отличающаяся тем, что цилиндрический элемент установлен внутри земляного бура с возможностью перемещения между положением установки, в котором вставка удерживает режущее средство в режущем положении между внешней периферийной поверхностью вставки и внутренней окружной стенкой земляного бура, и положением возвращения, в котором вставка втягивается, высвобождая режущее средство из положения между внешней периферийной поверхностью вставки и внутренней окружной стенкой земляного бура.1. Insert for holding with the possibility of releasing the cutting means in the earthen rock, containing a cylindrical element, characterized in that the cylindrical element is installed inside the earth auger with the ability to move between the installation position, in which the insert holds the cutting means in the cutting position between the outer peripheral surface of the insert and the inner circumferential wall of the earth drill, and the return position, in which the insert is retracted, releasing the cutting means from the position between the outer perimeter The serial insert surface and the inner circumferential wall of the earth auger. 2. Вставка по п. 1, отличающаяся тем, что она содержит ряд радиально размещенных и проходящих продольно шпоночных канавок, образованных вокруг внешней окружной стенки и у нижнего конца элемента для размещения и удержания режущего средства в режущем положении. 2. The insert according to claim 1, characterized in that it contains a series of radially arranged and longitudinally extending keyways formed around the outer circumferential wall and at the lower end of the element for positioning and holding the cutting means in the cutting position. 3. Вставка по п. 2, отличающаяся тем, что верхний конец вставки имеет профиль, вызывающий вращение режущего средства вокруг продольной оси бура, когда режущее средство устанавливается в земляном буре для выравнивания режущего средства с шпоночными канавками. 3. The insert according to claim 2, characterized in that the upper end of the insert has a profile that causes the cutting tool to rotate around the longitudinal axis of the drill when the cutting tool is installed in the earthen drill to align the cutting tool with keyways. 4. Вставка по п. 3, отличающаяся тем, что верхний конец вставки имеет два противоположных пика, способных контактировать с инструментом, используемым для транспортировки режущего средства к земляному буру и от него, причем в рабочем положении при примыкании инструмента к пикам его можно поворачивать относительно продольной оси бура, чтобы выравнять режущее средство с шпоночными канавками. 4. The insert according to claim 3, characterized in that the upper end of the insert has two opposing peaks capable of contacting the tool used to transport the cutting means to and from the earth drill, and in the working position when the tool adjoins the peaks it can be rotated relative to the longitudinal axis of the drill to align the cutting tool with the keyways. 5. Вставка по п. 4, отличающаяся тем, что она содержит направляющее средство для передвижения вставки в продольном направлении между положением установки и положением возвращения. 5. The insert according to claim 4, characterized in that it comprises guide means for moving the insert in the longitudinal direction between the installation position and the return position. 6. Вставка по п. 3, отличающаяся тем, что направляющее средство содержит рейку или канал, образованные на внешней периферийной поверхности вставки и способные зацеплять канал или рейку, соответственно образованные на внутренней периферийной поверхности земляного бура. 6. The insert according to claim 3, characterized in that the guide means comprises a rail or channel formed on the outer peripheral surface of the insert and capable of engaging the channel or rail, respectively formed on the inner peripheral surface of the earth drill. 7. Вставка по п. 6, отличающаяся тем, что она содержит ряд продольно проходящих каналов на внутренней периферийной поверхности вставки для образования канала протекания жидкости, используемой для охлаждения и смазки режущего средства при работе земляного бура. 7. The insert according to claim 6, characterized in that it contains a series of longitudinally extending channels on the inner peripheral surface of the insert to form a fluid flow channel used to cool and lubricate the cutting means during the operation of the earth drill. 8. Вставка по п. 4, отличающаяся тем, что она содержит первый кулачок для зацепления инструмента при движении последнего вверх на первое расстояние для перемещения вставки в положение возвращения. 8. The insert according to claim 4, characterized in that it comprises a first cam for engaging the tool while the latter moves upward at a first distance to move the insert to the return position. 9. Вставка по п. 8, отличающаяся тем, что она содержит средство для расцепления инструмента от кулачка при вытягивании инструмента вверх далее указанного первого расстояния. 9. The insert according to claim 8, characterized in that it comprises means for disengaging the tool from the cam when pulling the tool up further than the first distance indicated. 10. Вставка по п. 9, отличающаяся тем, что первый кулачок представляет собой выемку, выполненную в цилиндрическом элементе. 10. The insert according to claim 9, characterized in that the first cam is a recess made in a cylindrical element. 11. Вставка по п. 10, отличающаяся тем, что средство расцепления содержит конусную поверхность, ведущую в направлении вверх от выемки к внутренней периферийной поверхности цилиндрического элемента. 11.
