Excavator mechanical arm with prolonged service life
The invention relates to an excavator mechanical arm with a prolonged service life. The excavator mechanical arm comprises a body. Excavation fingers are arranged at the excavation end of the body in parallel, multiple convex ribs are evenly distributed on the inner wall of the bottom end of the body and are parallel with one another and perpendicular to the excavation end of the body, the two sides of each convex rib are connected with inner wall sliding slopes at the bottom end of the body, and multiple balls are evenly distributed in the center of each convex rib and embedded into the outer surface of the convex rib and can rotate freely. Each excavation finger comprises a finger rod and a finger tip, wherein the finger rod is connected to the excavation end of the body, and the finger tip is detachably connected to the finger rod. Grooves are formed in the outer surfaces of the finger rods, rotating rolls are arranged in the grooves, and the two sides of each rotating roll are installed on the inner walls of the two sides of the corresponding groove in a rotating mode.
