Drilling bucket with high soil unloading efficiency

A drilling bucket with high soil unloading efficiency relates to the field of drilling buckets, and comprises a bucket body, a drill bit arranged at the bottom of the bucket body and used for rotary drilling, and a non-return device arranged on the drill bit and used for enabling soil and stone to enter the bucket body and be stored in the bucket body, and the automatic opening and closing deviceis used for automatically connecting or disconnecting the other end of the drill bit and the other end of the side wall. The drilling bucket can solve the problem that the soil unloading efficiency ofthe drilling bucket is low. 一种卸土效率高的钻斗，涉及钻斗领域，包括桶体，桶体底部设置用于旋转钻进的钻头，钻头的一端与桶体的侧壁的一端铰接，还包括：止回装置，设置于钻头上用于使土石进入桶体内部并保存在桶体内部；自动开合装置，用于使钻头的另一端与侧壁的另一端自动连接或自动断开。本实用新型能够解决钻斗卸土效率较低的问题。
