SOIL TILLAGE IMPLEMENT Russian patent published in 1995 - IPC

FIELD: agricultural engineering. SUBSTANCE: implement has a toolbar with an attached tine with a ring and side knives. The lower part with a chisel is displaced forward relative to the upper part in the direction of the implement movement. The rear end of the upper part of the body is displaced back relative to the lower part, and the side profile of each side part is hysteresis. The side parts are asymmetric. One side part is displaces forward relative to the other part by width "b" of the lower side part of the body displaced forward. The side parts are equal in surface area, and the involute of their surface is a couple of hysteresis curves truncated at the narrower ends. One half of the involute is mirror image of the other turned in the involute plane through an angle of 180 deg with alignment of the involuted surface end with the end of the other surface of the body side part. EFFECT: higher tillage quality; lower drag resistance. 5 dwg
