Efficient dosing device for oil well shaft

The utility model belongs to the technical field of oil wells, and particularly relates to an efficient dosing device for an oil well shaft, which comprises a storage device, a stirring device and a cleaning device. A stirring rod is rotatably connected to the inner side of the hollow pipe, a limiting ring is fixedly connected to the outer side of the stirring rod, a first gear is fixedly connected to one end of the stirring rod, a rotating shaft is fixedly connected to the tail end of a main shaft of the second motor, and a second gear is fixedly connected to the outer side of the rotating shaft. A connecting frame is driven by a first motor to enable a hollow pipe to rotate, so that a stirring rod is driven by the hollow pipe to rotate, liquid medicine on the inner side of a shell is stirred in the horizontal direction, meanwhile, a rotating shaft is driven by a second motor to enable a second gear to rotate, and a corresponding first gear rotates through the second gear; and the stirring rod drives the lim
