The invention relates to an excavating device, in particular to an efficient excavating device for mineral mining. The efficient excavating device for mineral mining saves time and labor. In order to achieve the aims, the efficient excavating device for mineral mining comprises wheels, an excavating vehicle, a first swing base, a lifting frame, a first connecting rod, a sector gear, an air cylinder, a rack, a sliding rail, a fixed plate, a connecting block, a second connecting rod and the like; the wheels are arranged at the bottom of the excavating vehicle in a left-and-right symmetry manner, the lifting frame and the second swing base are arranged on the top of the excavating vehicle, the lifting frame is located on the left side of the second swing base, and the sector gear is hinged to the second swing base. The effects of saving time and labor and being high in excavating speed and easy to operate are achieved, the air cylinder stretches out and draws back, a breaking hammer is driven to continuously break ores, meanwhile, an excavating hoe continuously excavates the ores, and the two actions can be finished at the same time.
