Abstract
The utility model belongs to the construction machinery, and particularly relates to an excavating device on an excavator. The excavating device is characterized in that a hydraulic cylinder is arranged between a large arm and a support seat; and the hydraulic cylinder is positioned in a hollow cavity of the large arm. The excavating device has the advantages of long service life and high working stability.
Description
Technical field:
The utility model belongs to engineering machinery, is specifically related to the excavating gear on a kind of excavator.
Background technology:
Its big arm of existing excavator be by and bearing between the hydraulic jack lifting rotate, its hydraulic jack is positioned at the outside of big arm, its shortcoming is in mining process, sandstone soil in the bucket drops, easily collide hydraulic jack, cause the hydraulic jack damage, influenced its application life.
Summary of the invention:
The purpose of this utility model provides a kind of long service life, the excavating gear that job stability is high.
The technical solution of the utility model is: a kind of excavating gear, comprise bearing, big arm, forearm and bucket, big arm one end pivoting support, the other end and forearm one end are hinged; the hinged bucket of the forearm other end; establish hydraulic jack between big arm and forearm; establish hydraulic jack between forearm and the bucket, it is characterized in that: establish hydraulic jack between big arm and bearing, hydraulic jack is positioned at the hollow cavity of big arm.
Owing to adopt technique scheme; between big arm and bearing, establish hydraulic jack; hydraulic jack is positioned at the hollow cavity of big arm; hydraulic jack has been played protective effect; prevented dropping from bucket because of sandstone soil; cause the damage of hydraulic jack, have the hydraulic jack long service life, the advantage that job stability is high.
Description of drawings:
Come the technical solution of the utility model is described further below in conjunction with the drawings and specific embodiments.Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
With reference to the accompanying drawings, a kind of excavating gear comprises bearing 1, big arm 2, forearm 3 and bucket 4, big arm
One end pivoting support 1, the other end and forearm 3 one ends are hinged; the hinged bucket 4 of forearm 3 other ends, establish hydraulic jack 5 between big arm 2 and forearm 3, establish hydraulic jack 6 between forearm 3 and the bucket 4; establish hydraulic jack 7 between big arm 2 and bearing 1, hydraulic jack 7 is positioned at the hollow cavity of big arm 2.
