Excavator bucket
The invention relates to an excavator bucket. The problem that an existing excavator bucket is difficult to adapt to excavation of original sediment materials. According to the excavator bucket, the bucket shape parameters of the bucket are as follows: the digging angle theta 1 of the bucket is more than or equal to 90 degrees and less than or equal to 94 degrees; the opening angle theta 2 is more than or equal to 16 degrees and less than or equal to 20 degrees; the edge angle theta 3 of a side cutter plate is more than or equal to 40 degrees and less than or equal to 50 degrees; the inclination angle theta 4 is more than 0 degree and less than or equal to 3 degrees; the width-depth ratio W/D is greater than or equal to 1 and less than or equal to 1.25; the overhang distance L is greater than or equal to 0.6 D; and the unit cutting force 1/(QV*W):1/(QV*W) is more than or equal to 180N/mm<2>. By optimizing the bucket shape parameters of the bucket, the resistance of excavating and exploiting raw sediment materials by the bucket is reduced, the cutting force of the bucket is large, the cutting speed is high, the operation efficiency is high, and the oil consumption is low.
