Face shovel type bucket of mining excavator and excavator
The face shovel type bucket of the mining excavator and the excavator are characterized in that the bucket is connected to the front portion of a bucket rod and is driven by the bucket rod to stretch out or retract back, a bucket body is connected with a lifting beam, the lifting beam is connected with a steel wire rope and used for being driven by the steel wire rope to ascend or descend, and the bucket body comprises a bucket body and a bucket lip; the bucket lip is arranged on the front portion of the bucket body, the whole bucket lip is of an arc-shaped structure, the bucket lip comprises a left bucket lip body, a middle bucket lip body and a right bucket lip body, and the left bucket lip body and the right bucket lip body are connected to the two sides of the middle bucket lip body; a plurality of bucket teeth and sheaths are arranged on the upper portion of the bucket lip at intervals. The large-arc bucket lip avoids stress concentration, reduces the probability of defect generation, and reduces downtime and maintenance cost caused by bucket lip faults.
本发明公开了一种矿用挖掘机正铲式铲斗及挖掘机，铲斗连接在斗杆的前部，在斗杆带动下伸出或缩回，铲斗斗体上连接有提梁，提梁与钢丝绳连接，用于在钢丝绳带动下进行提升或下降，铲斗斗体包括斗体本体和斗唇，斗唇设置在斗体本体的前部，斗唇整体为圆弧形结构，斗唇包括左侧斗唇、中部斗唇和右侧斗唇，左侧斗唇和右侧斗唇连接在中部斗唇的两侧；斗唇的上部间隔设置有多个斗齿和护套。大圆弧斗唇避免了应力集中，减少了缺陷产生的几率，减少了因斗唇故障而造成的停机时间和维修费用。
