(.54) РАБОЧЕЕОБОРУДОВАНИЕ ЭКСКАВАТОРА(.54) OPERATING EQUIPMENT

1one

Изобретение отнеситс к землеройней технике и может быть использовано дл рыхлени мерзлых и плотных грунтов , а также асфальтобетонных покрытий .The invention relates to excavation technology and can be used for loosening frozen and dense soils, as well as asphalt concrete pavements.

Известно навесное оборудование к экскаватору дл рыхлени мерзлых и плотных грунтов, выполненное в виде удельного инструмента, например пневмемолота , установленного с возможностью возвратно-поступательного движени в направл ющих, смонтированных на внешней стороне руко ти 1 .Known attachments to an excavator for loosening frozen and dense soils, made in the form of a specific tool, such as a pneumatic hammer, installed with the possibility of reciprocating movement in guides mounted on the outer side of the arm 1.

Недостатком указанного оборудовани вл етс низка производитель- ,5 кость, обусловленна его технико-экономическими данными.The disadvantage of this equipment is low production, 5 bone, due to its technical and economic data.

Наиболее близким к предлагаемому по технической сущности и достигаемому результату вл етс рабочее еберу-2р дование экскаватора, содержащее рабочий орган, кронштейн его подвески, оснащенный профильным башмаком,рычаг , шарнирно соединенный с рабочимThe closest to the proposed technical essence and the achieved result is a working eber-2 building of an excavator containing a working body, a bracket of its suspension, equipped with a profile shoe, a lever pivotally connected to the working

органом одним концом и взаимодействующий с профильным башмаком посредством ролика, установленного на другом конце, и силовой цилиндр управлени рычагом 2.the body at one end and interacting with the profile shoe by means of a roller mounted at the other end, and the control cylinder of the lever 2.

Рабочий орган заглубл ют с пемещью силевого цилиндра, производ т отламывание грунта путем поворота ипи передвижени платформы, затем поднимают рабочий орган из забо и удал ют грунт ковшом.The working body is buried with the space of the power cylinder, the soil is broken off by rotating the platform and then the working body is lifted from the bottom, and the soil is removed with a bucket.

К недостаткам известного решени следует отнести, несовместимость процессов рыхлени и экскащации, недостаточную зону действи навеснего оборудовани , невезмежность установки рабочего органа под нужным углом к разрыхл емой поверхности, что отрицательно вли ет на технологические возможности экскаватора.The disadvantages of the known solution include the incompatibility of the loosening and excavation processes, the insufficient area of attachment of equipment, poor installation of the working body at the right angle to the loosened surface, which adversely affects the technological capabilities of the excavator.

Claims

The purpose of the invention is to expand the technological capabilities of the excavator and increase its productivity in the development of frozen and imoTtoax soils. This goal is achieved by the fact that the suspension arm is pivotally mounted on the axis of the junction of the boom with the arm and is equipped with a hydraulic cylinder for turning the ripper, and the hydraulic cylinders for controlling the lever are connected with the boom. FIG. 1 -study excavator with attachments, total airfield; in fig. 2 - the same in the development of the excavator. On the excavator 1, the working equipment was mounted, including boom 2 J, handle Sj connected to boom 2, axis 4p bucket 5, active ripper 6, lever 7 $ pivotally connected to ripper 6 and cylinders 8 of its control and suspended on the axis 4 of the connection of the boom 2 with the handle 3, and the cylinder 9 controlling the working body 6. Moreover, the cylinders 8 controlling the lever 7 are pivotally connected to the boom 2, the working equipment operates as follows. The manipulator with cylinders 8 and 9 orient the ripper to the place of loosening. The boom 2 is lowered until the ripper 6 is in contact with the ground. The ripper 6 oscillates, continuing to lower the boom 2. As the soil loosens, the ripper 6 deepens. Produce the deepening of the ripper 6 at several points, the latter is removed from the loosening zone, pushing it towards the boom 2 by the Cylinders 8, and the loosened soil is chosen with a bucket 5. The working equipment of the excavator is lowered in when the bucket 5 is in contact with the ground. At the same time, the manipulator with cylinders 8 and 9 lower the ripper 6 onto the ground, excite the latter, the cylinders B deepen the cultivator 6, and the bucket 5 is brought under the loosening soil, fill it and lift the working equipment from the bottom, simultaneously ripping the ripper 6 boom 2, cylinders 8, then rotate the platform and unload the bucket 5. Further, the digging cycle is repeated. Claims of the excavator's working equipment, including boom and arm connected by a hinge axis, bucket, hydraulic control cylinder suspension arm and active ripper lever pivotally connected to the lever, characterized in that, in order to expand its technological capabilities, the suspension arm is pivotally mounted on the joint axis the boom with the arm and is equipped with a hydrocylide rotor for the ripper, and the control hydraulic cylinders are connected to the boom.
