The cylinder rod of cylinder is connected with the rotational support point on the cursor, and the principal arm is provided with placement corresponding with master cylinder
Groove, multiple startup cylinders are fixed with the bottom of resettlement groove, start the end connecting partition of cylinder, dividing plate is provided with and the master
The identical deep-slotted chip breaker of cylinder side face.
A kind of digging arm of above-mentioned excavator, the equidistant straight line arrangement in resettlement groove of the multiple startup cylinder, and
Positioned at the underface of the master cylinder.
A kind of digging arm of above-mentioned excavator, the cursor are provided with the transmission cylinder being connected with the Excavating bucket.
A kind of digging arm of above-mentioned excavator, the principal arm are provided with fixing axle, and fixing axle is by supporting cylinder with digging
Dig the connection of owner's body.
A kind of digging arm of above-mentioned excavator, the principal arm are fixed in excavator main body.
Beneficial effects of the present invention are：The cursor of the digging arm is provided with rotational support point and the fixed strong point, even
Fitting is flexibly connected with the fixation strong point on cursor, and principal arm is provided with fixed seat, and master cylinder is flexibly connected in fixed seat, main
Rotational support point connection in the cylinder rod and cursor of cylinder, principal arm are provided with resettlement groove corresponding with master cylinder, disposed
The bottom of groove is fixed with multiple startup cylinders, starts the end connecting partition of cylinder, and dividing plate is provided with to coincide with master cylinder side face
Deep-slotted chip breaker, master cylinder primarily serve drive cursor rotate purpose, usually master cylinder fold in the resettlement groove of principal arm,
When needing to use, start cylinder band dynamic dividing plate and rise, the side face of deep-slotted chip breaker and master cylinder on dividing plate coincide, so as to by master cylinder
Ejected out of resettlement groove, highest is raised to by the dividing plate for controlling the startup cylinder close to cursor side to connect so that master cylinder
It is in certain angle of inclination relative to principal arm so that master cylinder most laborsaving and not easy damaged when driving cursor to rotate.
Brief description of the drawings
Fig. 1 is the schematic diagram of the present invention；
