Screw-driven pumping unit

The invention relates to the technical field of oil pumping units, and discloses a screw driving type oil pumping unit which comprises a base, a base opening is formed in the middle of the base, outer supports are fixedly mounted on the two sides of the upper surface of the base, a lower transverse frame is fixedly mounted on the inner sides of the outer supports, and an oil well mounting opening is formed in the middle of the lower transverse frame. A main screw rod is movably installed on the upper surface of the lower transverse frame, one side of the main screw rod penetrates through the bottom of the lower transverse frame and extends to the position below the lower transverse frame, and a load bearing is fixedly installed at the joint of the lower transverse frame and the main screw rod. The main screw, the turbine, the spiral rolling bearing and the worm are used in cooperation, the device cannot be disjointed in the using process, oil injection work can be directly conducted due to the arrangement of
