At the upper half of a three-layer mouldboard to adjust its angle of bend from the rear side the horizontal grooves are made which are parallel to each other and the junction line of the ploughshare and the mouldboard, and connected by a support plate. At the same time, the elastic plates have a curved shape, they are evenly and vertically attached between the grooves: rigidly in the lower part of the elastic plate and using the adjusting screws - in its upper part. The upper half of the plate is attached to the rack by the turnbuckle with a hinge, and the lower half via support plate is attached using the screws and the hinges to the attachment plate which is rigidly connected through a shoe to the rack.EFFECT: in the working element the ability is provided to adjust the operating width and the installation angle of the ploughshare to the bottom.3 cl, 5 dwg |
