UNDERCOVER SOIL DISRUPTER Russian patent published in 2015 - IPC A01B13/16 A01B13/08 A01B15/00 E02B11/02 

FIELD: agriculture.

SUBSTANCE: undercover soil ripper comprises milling chisel plough knife with a rack (2) and a hollow mole blade. Inside the mole blade on the shaft (6) the thrust bearings (7) are mounted. The shaft (6) is connected through the connecting insert (12) to the soil disrupter (15) in the form of a conical spring. The connecting insert (12) has left-handed threaded recesses. The housing of the hollow mole blade with the thread on both ends is cut horizontally lengthwise in half. The halves (3, 4) of the mole blade are welded to the milling chisel plough and covered by the expansion head (8) and a nut (9) with the sealing ring (10). The side slits of the mole blade housing are sealed with flat gaskets in the form of an I-beam. The spring of the disrupter in the front part is made in the form of a cylinder in the middle part in the form of a cone with the angle of expansion α=15…25°, in the rear part in the form of the rotation paraboloid y=xn, where n=0.5…0.7. The cross-section of the spring in the working part is made in the form of a wedge with an angle of inclination to the axis of the spring wire β=10…20°. The working face of the spring is coated with a layer of wear-resistant material.

EFFECT: ensuring quick assembly and disassembly of the mole blade and intensive quality soil crumbling.
