Improve again, be upwardly formed mounting portion on the working arm upper side wall, the bucket cylinder be articulated with mounting portion it
On, by setting mounting portion, easy to being hinged for bucket cylinder cylinder body.
Improve again, the protective cover for oil tank includes being formed at cover plate above bucket cylinder, is formed at bucket cylinder both sides
Side plate, together with cover plate and side plate vertical welding.
Compared with prior art, the utility model has the advantage of：The protective cover for oil tank of the utility model, first connecting rod,
Quadric chain is formed between second connecting rod and working arm, when bucket cylinder stretches, protective cover for oil tank is moved with piston rod
Dynamic, no matter bucket cylinder, which is in, is shunk or stretches out, and protective cover for oil tank is moved with piston rod and can protected always all the time
Bucket cylinder piston rod, so that in operation process, can protect the cleaning of bucket cylinder piston rod, improve making for bucket cylinder
Use the service life.
