Abstract
PURPOSE: To easily perform a formation of a trench fertilizing and filling back by a mechanism wherein inclined and rotating trenching device and spiral type filling back device both of which are freely removed are fitted through shafts to both sides of lower parts of a power transmission case.
CONSTITUTION: A pair of rotary type trenching device 5 fitted in a V-shape to a rotating shaft are rotated through a power transmission case 4 in an up-cut milling system to form a trench 20 having a wider width at the upper part. At this time, the digged soil is piled 21 at a far away part of the trench 20. After a fertilizer is thrown into the trench 20, the trenching device 5 are removed and filling back device 6 are mounted. The axis of a spiral wing 22 of the filling back device 6 is formed to be inclined lower and lower when the wing 22 goes far from the case 4 and in a small diameter. The soil transporting operation to the case 4 side becomes better through the inclined rotation of this spiral wing 22. Further, even when a quantity of soil increases at nearer parts to the trench 20, an effective measure can be taken because the sprial has a large diameter.
