Description

Изобретенгуе относитс к рабочим орга нем землеройных машинj используемых дл строительства различных объектов и сооружений .The invention relates to the working bodies of earth-moving machines used for the construction of various objects and structures.

Известен ковш экскаватора,- преднаана- ченный дл копани траншей различной заданной шир1шы, у которого боковые стенки установлены с возможностью перемещени относительно корпуса в направлении, перпендикул рном оси копани и фиксации их в заданном положении l.The excavator bucket is known, intended for digging trenches of various predetermined width, in which the side walls are mounted with the possibility of movement relative to the body in the direction perpendicular to the digging axis and fixing them in the predetermined position l.

Недостатками такого ковша вл етс сложность устройства автоматизированного привода, обеспечивающего параллельное выдвижение боковых стенок ковща и невоэможность импользовани ковща дл пр мой лопаты,The disadvantages of such a bucket are the complexity of an automated drive device that provides parallel extension of the side walls of the bucket and the impossibility of using the bucket for a straight shovel,

Известен также ковщ экскаватора, включающий челюсти с днищем и закругленной частью, установленные на общей оси с воаможностью поворота во взаимно противоположных на:аравлени х посредством силового цилиндра 2J.Also known is the excavator bucket, which includes the jaws with the bottom and the rounded off part, mounted on a common axis with the possibility of turning into mutually opposite ones on the plane by means of the power cylinder 2J.

Такой ковш допускает использование его без перемонтажа в качестве пр мой и об- Such a bucket allows its use without rewiring as a direct and secondary

ратной лопаты. Однако он не может быть использован дл рыть транщей переменно ширины и вертикальных выемок.military shovels. However, it cannot be used to dig trenches of variable width and vertical grooves.

Целью изобретени вл етс создание ковша, который может быть использован без перемонтажа дл рыть траншей переменной ширины и вертикальных выемок.The aim of the invention is to create a bucket that can be used without rewiring to dig trenches of variable width and vertical grooves.

Указанна цель достигаетс тем, что закругленные части челюстей установлены внахлест, а поверхность их контакта выполнена по форме цилиндра, ось которого совпадает с осью поворота челюстей.This goal is achieved by the fact that the rounded parts of the jaws are overlapped, and the surface of their contact is made in the shape of a cylinder, the axis of which coincides with the axis of rotation of the jaws.

На чертеже изображен предлагаемый ковщ экскаватора.The drawing shows the proposed excavator bucket.

Claims

The excavator bucket includes a smaller jaw 1 and a larger jaw 2 with bottoms, overlapped and hinged on axis 3. The contact surface 4 of the jaws is shaped like a cylinder, the axis of which coincides with the axis of rotation 3 of the jaws. Axis 3 is fixed on the crocodile 5 mounted on the handle 6 of the excavator. The cutting edges 7 of the jaws 1 and 2 are sharpened at an acute angle along the entire perimeter. In the upper part of the jaws 1 and 2 there are straps 8 and 9, to which are attached the rods 10 of the actuator, e.g. with the bracket. The device operates as follows. Under the action of the rods 1O of the power cylinder 11, the rotation 8 and 9 are rotated about the axis 3, which in turn rotate the jaws 1 and 2 by an external angle. At the same time, the value of the bucket parameter, the definite trench digging width, is changed. Due to the constructive implementation of the jaws 1 and 2, their expansion to certain limits does not cause the formation of a gap between the rounded parts of the jaws. The cutting edges 7 perform the function of partially cleaning the working surfaces of the bucket. The described bucket can perform work on a fragment of vertical grooves in the form of wells and m for foundation shoes separately hundred hundred columns. To do this, the jaws 1 and 2 are moved apart until a gap is formed, the carpet is lowered onto the ground. bucket jaws and it produces a closing lift. Claims of an excavator bucket, including jaws with a bottom and a rounded part, mounted on a common axis can be rotated in mutually opposite directions by means of a power cylinder, characterized in that with the aim of using it without rewiring to dig trenches of variable width and vertical grooves rounded parts of the jaws are overlapped, and the surface of their contact is made in the shape of a cylinder, the axis of which coincides with the axis of rotation of the jaws.
