The invention relates to a scraper structure of an improved automatic filter press. The scraper structure of the improved automatic filter press comprises a fixed shaft (3) and a rotating shaft (4), wherein the fixed shaft (3) is arranged between two side plates (12), the rotating shaft (4) is rotatably sleeved on the fixed shaft (3), a baffle plate (11) is downwardly extended on the lower portion of the rotating shaft (4), a gliding slot is run through the baffle plate (11), and is arranged from top to bottom and is vertical to the fixed shaft (3), a driving shaft (10) is inserted into the gliding slot, one end of the driving shaft (10) is fixed on a fixed base (5), a rotating screw (9) and a spring (7) are sleeved on the other end of the driving shaft (10), a scraper fixed connecting part (4) is arranged on the upper portion of the rotating shaft (4), and a scraper is fixed on the upper end of the upper portion of the rotating shaft (4). The scraper structure of the improved automatic filter press is simple in structure, easy to produce and assemble, and is convenient to generalize and use.
