Bucket and mining excavator
The bucket comprises a bucket body, the bucket body is provided with a containing groove used for containing materials, the containing groove is provided with a front opening used for receiving the materials and a bottom opening used for discharging the materials, and bucket teeth are arranged at the position, at the lower end of the front opening, of the bucket body; the bucket bottom door is mounted at one end of the bottom opening of the bucket main body and can pivotally move between an open position and a closed position relative to the bucket main body so as to open and close the bottom opening; the balance beam comprises a body and at least two rope grooves, the body is hinged to the upper end of the front opening of the bucket body, and the at least two rope grooves are symmetrically formed in the two sides of the body and used for being connected with a lifting steel wire rope of the mining excavator. The working range of the bucket can be widened, the unloading height of the excavator is increased, the problems that when the excavator is matched with a crushing station of the same specification to work, bucket bottom impact is large, and bucket opening is difficult are solved, and the weight of the bucket is effectively reduced.
本发明公开了一种铲斗及矿用挖掘机，该铲斗包括：铲斗主体，铲斗主体具有用于容纳物料的容纳槽，容纳槽具有用于接收物料的前部开口和用于排出物料的底部开口，铲斗主体在前部开口的下端设有斗齿；铲斗底门，铲斗底门安装在铲斗主体的底部开口一端，能够相对于铲斗主体在打开位置和闭合位置之间枢转运动，以打开和关闭底部开口；均衡梁，均衡梁包括本体和绳槽，本体铰接在铲斗主体的前部开口的上端，绳槽包括至少两个，至少两个绳槽对称布置在本体的两侧，用于连接矿用挖掘机的提升钢丝绳。本发明能够提高铲斗的工作范围，增加挖掘机的卸载高度，避免挖掘机与同规格的破碎站匹配工作时存在开斗时斗底冲击大、开斗困难等问题，并有效减轻铲斗重量。
