An apparatus for separating and removing gravel of a field is provided to prevent damages to a cultivating apparatus plowing up or harrowing the field, and to reduce the work load. In an apparatus for separating and removing gravel of a field, in which power transmitted from a driving shaft(42) of an engine(40) is transmitted to a blade driving shaft(25) and first and second moving track wheels(21,22) through first and second power transmission units(13,12), and rotary bars(16) connected to the operating handle are vertically rotated by first bent bars(19), connecting rods(17) and second bent bars(18) according to the vertical rotation of an operating handle(20) positioned at the front side of a body(50), the apparatus is characterized in that gravel separating transfer blades(15) formed at predetermined blade intervals on a blade driving shaft(25) of the rotary bars, the gravel separating transfer blades are formed to be horizontally symmetrical to each other around the central blade thereof on the driving shaft, the gravel separating transfer blades rotate while forming a spiral track along end portions thereof such that gravel separated from the field is automatically transferred to the left or right side. |
