Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0018] like Figures 1 to 3 As shown, an excavator includes a machine body 20 , a slewing device 30 , an excavating device 10 and a running device 40 , and the machine body 20 is mounted on the running device 40 through the slewing device 30 .
[0019] Excavator 10 comprises: driving arm 101, driving arm oil cylinder 102, arm 103, arm oil cylinder 104, outer bucket 109, outer bucket oil cylinder 105, outer bucket linkage mechanism 107, inner bucket 1010, inner bucket Oil cylinder 106 and inner bucket linkage 108 .
[0020] The rear end of the driving arm 101 is hingedly mounted on the machine body 20 , and the front end is hingedly mounted on the stick 103 . One end of the driving arm cylinde...

The invention discloses an excavating device and an excavator. The excavating device comprises a machine body, an excavating device, a rotating device and a traveling device, wherein the machine body is installed on the traveling device through the rotating device. The excavating device comprises a driving arm, a driving arm oil cylinder, a bucket rod, a bucket rod oil cylinder, an outer bucket, an outer bucket oil cylinder, an outer bucket link mechanism, an inner bucket, an inner bucket oil cylinder and an inner bucket link mechanism; one end of the bucket rod oil cylinder is hinged to the middle of the driving arm, the other end of the bucket rod oil cylinder is installed at the rear end of the bucket rod, the inner bucket and the outer bucket are hinged to the front end of the bucket rod, the inner bucket can be contained in the outer bucket, one end of the outer bucket oil cylinder is hinged to the rear end of the bucket rod, and the other end of the outer bucket oil cylinder is connected with the outer bucket through the outer bucket link mechanism. The excavating device has the advantages that power is transmitted to the inner bucket and the outer bucket through independent oil cylinders respectively, the inner bucket and the outer bucket can act synchronously as well as move independently, and the excavating efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of engineering equipment, and in particular relates to an excavating device and an excavator. Background technique [0002] At present, in the field of construction machinery, excavators are an important construction equipment. However, for most excavators, their working process is slewing-excavation-unloading-returning, and there are a large number of invalid actions that have nothing to do with excavation work in their working process, which leads to low working efficiency of the excavator. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art, and provide an excavating device and an excavator, which can improve the working efficiency of the excavator. [0004] In order to solve the problems in the prior art, the present invention discloses an excavating device, which includes a driving arm, a driving arm cylinder, an arm and an arm cylin...
