Embodiment in type, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, fall within the protection scope of the utility model.The embodiments of the present invention are described in detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of bucket arm cylinder resilient support system, including elastic mechanism, the elastic mechanism are arranged in swing arm 5
Between bucket arm cylinder 4, the elastic force generated when elastic mechanism is pressurized passes to bucket arm cylinder 4, offsets bucket arm cylinder 4 itself
Gravity, so that bucket arm cylinder 4 is only drawn or pressed two states.
A preferred embodiment of elastic mechanism in above-described embodiment is given below:
With continued reference to shown in Fig. 1, elastic mechanism includes support plate I 1, support plate II 3 and elastomeric element；
Support plate I 1 is fixed on bucket arm cylinder cylinder body, and support plate II 3 is fixed on swing arm sealing plate, and elastomeric element is connected to
Between support plate I 1, support plate II 3.
Support plate I in above-described embodiment, a preferred embodiment of support plate II is given below:
With continued reference to shown in Fig. 1, the top surface of support plate I 1 is arcwall face, after top surface and bucket arm cylinder cylinder body fit closely
It is fixed together by welding manner；The bottom surface of support plate I 1 is connected with the top of elastomeric element.Support plate II 3 is length
Cube plate or square plate, bottom surface are fixed together after fitting closely with swing arm sealing plate by welding manner；Support
The top surface of plate II 3 is connected with the lower part of elastomeric element.
A preferred embodiment of elastomeric element in above-described embodiment is given below:
With continued reference to shown in Fig. 1, elastomeric element is compressed spring 2, by welding with support plate I 1, support plate II
