The invention provides an automatic sand sieving machine comprising a rack. The upper end of the rack is provided with a shell, and the shell is internally provided with a screen frame horizontally; the rear end of the inner wall of the shell is fixedly provided with a motor and a gear ring arranged below the motor, and an output shaft of the motor is connected to a first gear engaged with a second gear; the second gear is engaged in the gear ring, and rotatably provided with a rotating shaft fixed to the rear end of the screw frame by screws; and the right and left sides of the lower end of the screen frame are symmetrically provided with sliding rail structures fixed to the inner wall of the shell. The automatic sand sieving machine provided by the invention is simple in structure, and the screen frame can do circular motion in work, so that automatic sand sieving is achieved; thus, the efficiency is improved, and the sand sieving quality is improved; and the automatic sand sieving machine lays a foundation for the next working procedure.
Description
technical field [0001] The invention relates to the technical field of mold sand casting, in particular to an automatic sand screening machine. Background technique [0002] Molding sand is usually made of raw sand, binder (commonly used clay or tung oil, etc.) 30-50% of the total casting waste. At present, most of the sand is manually screened, and the sand is manually screened with a sieve, which is not only inefficient and wastes manpower and material resources, but also has poor results, which will affect the following processes. Contents of the invention [0003] 【1】Technical problems to be solved [0004] The technical problem to be solved by the present invention is to provide an automatic sand screening machine with simple structure, which can realize automatic sand screening and improve the quality of sand screening. [0005] 【2】Technical solution to solve the problem [0006] The present invention provides an automatic sand screening machine, comprising a fra...
