<p>The present invention relates to a disk plow frame which is connected to a rear side of an agricultural tractor for reclaiming agricultural farmland, especially the variable disk plow frame which is capable of adjusting the angle of left and right side disk plow frames and forward and backward length of a central plowshare. The present invention comprises the following: a tripod (1) which is connected to the rear side of the agricultural tractor; a central frame (3) with a V-shaped plowshare (2) which is connected to the tripod; and side frames (6) which include multiple rows of disk plowshares (5) arranged in a wing mode based on left and right connection stands (4) around the central frame (3). An internal variable frame (8) rotating along the longitudinal direction of the central frame (3) using a lower cylinder (7b) is installed on the central frame (3). Each side frame (6) is connected to each connection stand (4) of the central frame (3) using a hinge shaft (9a), and is connected to variable links (10) which are linked to an upper cylinder (7a) to adjust the angle around the connection stands (4) of the central frame (3).</p> |
