Improved oscillating bar screening machine

The utility model relates to the technical field of screening, in particular to an improved oscillating bar screening machine which comprises a base and a box body, the box body is fixedly connected to the upper surface of the base, a screening mechanism is arranged in the box body, an inclined plate is fixedly connected to the inner wall of the box body, and a fixing plate is fixedly connected to the outer wall of the box body. The fixing plate is fixedly connected with the top plate through the supporting columns. A first motor drives a disc to rotate, the disc drives a first supporting rod to move, the first supporting rod drives a sieve plate to move, the sieve plate drives a second supporting rod to move, the second supporting rod drives a roller to move, the roller rolls on a sliding way, the sieve plate screens materials on the surface when moving, and the materials meeting the requirements enter a collecting box through the sieve plate. Materials which cannot pass through the screening plate move in t
