Abstract
A working attachment of a trench digger consists of a frame and a drive section executive device as rings with teeth. On the frame a conical gearing is installed, there the drive pinion is connected to the shaft of power takeoff of the basic machine, and the driven one is placed on the vertical shaft. At the opposite end of the shaft a cylindrical pinion is fixed. On the front and the back vertical shafts in sequence a set of pinions is installed, those are surrounded with a set of rings. On the outer surface of the rings cutter teeth are installed in such a way that on the even and odd rings, if looking from above, those are at mirror arrangement. The teeth have cutter edge, back section and side sections that are tightened to the rings and have concave surfaces. To the opposite side surface a transition element is attached, with convexity to the side of the upper section of the tooth. The front surface of the tooth has concave character from the cutter edge to the upper point of the back section of the tooth. The teeth are installed in stepped way. The cutter edge of each following tooth rests at the upper point of the back section of the previous tooth with formation of inclined stepped surface at that.
