This invention relates to the field of mining excavator technology, specifically a rotatable hydraulic mining excavator, comprising an excavator body, an excavation mechanism mounted on the excavator body, and a control mechanism. A bucket is mounted on the excavation mechanism, with a planar thread embedded in the gap between two adjacent fixed blocks. A protective shell located outside the motor is fixedly connected inside the bucket, and a cover plate is screwed onto the protective shell. The bucket can be rotated directly by the boom, which drives the arm to lift, bringing the top of the bucket close to the coal mine at the top of the tunnel. The motor is then controlled by the excavator body's control components. When the motor rotates, it drives the rotating disc to rotate. Because the planar thread on the side wall of the rotating disc is embedded between two adjacent fixed blocks, the rotating rod is pushed out when the planar thread rotates. This allows the coal mine at the top of the tunnel to be excavated via a lever, eliminating the need to rotate the boom and arm to change the bucket's direction, thus reducing the operational difficulty for construction workers.
