Description

Loader-digger

Technical field

The utility model is mainly concerned with the engineering mechanical device field, refers in particular to a kind of excavation loading special equipment.

Background technology

Along with the technology of engineering machinery constantly develops, the special equipment under the various operating modes has appearred being adapted in a large number.Because the spatial constraints in tunnel, bigger digging machine or the loader of the work radius of gyration can not enter wherein, or can not work efficiently therein, thus occurred anterior responsible excavation push away take off, loader-digger (being called for short: dig installation) that the rear portion is responsible for carrying.The structure of loader-digger generally comprises walking mechanism, digs and take off mechanism and conveying mechanism in the prior art.Analyze theoretically, loader-digger is owing to the common relatively excavator of action cycle of work will be lacked, general 4-5 just can finish a work period second, and excavator was generally wanted about 10 seconds, and the length of each swing arm is greater than loader-digger on the excavator, stressed big than loader-digger, so loader-digger should dispose the bigger shovel that digs, overall efficiency just should be than common excavator height.If but existing loader-digger is not considered spatial constraints, real work efficient is lower than common excavator.Anatomize, find that there is following problem in existing loader-digger, thereby cause efficient not high:
