Description
Technical field
The present invention relates to grabbing to put forward machinery manufacturing technology field, specifically a kind of dust-collecting type is broken to grab bucket.
Background technology
Grab bucket is that a kind of folding mainly by the two combination buckets in left and right or multiple jaws captures and drawn off hanging for bulk material
Tool, grab bucket can be divided into two major classes of fluid pressure type grab bucket and mechanical grab bucket by type of drive, and fluid pressure type grab bucket is equipped with folding knot in itself
Structure, is typically driven with hydraulic jack, and hydraulic grab is applied in hydraulic pressure class special equipment than wide, such as hydraulic crawler excavator, liquid
Hoist tower etc. is pressed, and mechanically grab bucket is configured without opening-closing structure in itself, is generally driven by rope or connecting rod external force, it is special by operation
Point can be divided into twin rope grab and single rope grab, most commonly twin rope grab, although the species of existing grabbing arrangement is various more
Sample, but grab bucket can be frequently seen in actual life and captures some big thing blocks, because the size, the shape that capture thing differ,
The space of grab bucket is caused not make full use of, disposable crawl thing is less, and operating efficiency is low, and often can be appreciated that on-site
Grab bucket can produce substantial amounts of dust in the course of the work, and working environment is severe, and serious have impact on the healthy of operator,
Simultaneously during crawl, the thing of doping in thing block, staff does not know about simultaneously, may be doped with the metal that can not be crushed
Class thing block, when doping carries out broken, can cause irreversible damage, and if damaging, staff to device
It is difficult to carry out it maintenance replacement, delays in work is stagnated, influences the process of work.
The content of the invention
In order to solve the above problems, the invention provides a kind of broken grab bucket of dust-collecting type, grab bucket crawl can be solved
Big thing block, because the size, the shape that capture thing differ, causes the space of grab bucket not make full use of, disposable crawl thing compared with
Few, operating efficiency is low, and often can be appreciated that grab bucket can produce substantial amounts of dust, working environment in the course of the work on-site
Badly, it is serious to have impact on the healthy of operator, while during crawl, the thing of doping in thing block, work
Personnel do not know about simultaneously, may be doped with the metal class thing block that can not be crushed, and when doping carries out broken, device can be caused can not
The damage of reverse, and if damage, staff is difficult to carry out it maintenance replacement, and delays in work is stagnated, and influences work
