Technical field
The utility model relates to excavating equipment component technology field, is specifically related to a kind of collapsible working arm of excavating machine of amplitude-variable.
Background technology
Traditional excavator need to increase job area, generally excavator swing arm, dipper can be lengthened to increase job area, the simple excavator swing arm bucket arm length that increases, although can increase job area on degree, but traditional swing arm is a curved arc shape integral body, angle can not be adjusted, lift high, dig and deeply still be subject to swing arm curved arc restriction.Therefore simple lengthening swing arm, bucket arm length can not thoroughly solve the technical problem that excavator satisfies increases the job area demand.
The utility model content
Feature and advantage of the present utility model are partly statement in the following description, perhaps can describe obviously from this, perhaps can learn by putting into practice the utility model.
for solving the problem of prior art, the utility model provides a kind of collapsible working arm of excavating machine of amplitude-variable, the utility model changes simple swing arm and the bucket arm length of increasing, to enlarge the technology path of excavator working range, be flexibly connected at least one section luffing arm between swing arm and dipper, so just make the excavation height of excavator and the structural limitations that excavation depth is not subjected to swing arm, greatly increased the excavation scope, and in equal job area, luffing arm size is short, therefore more flexible, can mate larger bucket or large-scale attaching, operating efficiency is higher, more economical.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be:
the utility model provides a kind of collapsible working arm of excavating machine of amplitude-variable, comprise swing arm and dipper, also comprise at least one section luffing arm and corresponding amplitude oil cylinder that is flexibly connected successively, this luffing arm of first paragraph and this swing arm are flexibly connected, this luffing arm of final stage and this dipper are flexibly connected, the cylinder body of corresponding this amplitude oil cylinder of this luffing arm of first paragraph is fixed on this swing arm, this luffing arm of its piston rod and first paragraph is flexibly connected, the piston rod of the corresponding amplitude oil cylinder of this luffing arm of final stage and this dipper are flexibly connected, the cylinder body of corresponding this amplitude oil cylinder of remaining this luffing arm is fixed on this luffing arm the last period, the piston rod of this amplitude oil cylinder and this luffing arm are flexibly connected.
According to embodiment of the present utility model, the tail end of this luffing arm of first paragraph and the head end of this swing arm are flexibly connected.
According to embodiment of the present utility model, the head end of this luffing arm of final stage and the tail end of this dipper are flexibly connected.
According to embodiment of the present utility model, the cylinder body of corresponding this amplitude oil cylinder of this luffing arm of first paragraph is fixed on the tail end of this swing arm.
According to embodiment of the present utility model, the piston rod of corresponding this amplitude oil cylinder of this luffing arm of first paragraph and the tail end of this luffing arm of first paragraph are flexibly connected.
According to embodiment of the present utility model, the luffing arm that is flexibly connected successively is end to end.
the beneficial effect of utility model: the utility model provides a kind of collapsible working arm of excavating machine of amplitude-variable, the utility model changes simple swing arm and the bucket arm length of increasing, to enlarge the technology path of excavator working range, be flexibly connected at least one section luffing arm between swing arm and dipper, so just make the excavation height of excavator and the structural limitations that excavation depth is not subjected to swing arm, greatly increased the excavation scope, and in equal job area, luffing arm size is short, therefore more flexible, can mate larger bucket or large-scale attaching, operating efficiency is higher, more economical.
