PLOUGH FOR 45 HP TRACTOR WITH COUPLING DEVICE ADJUSTABLE ON THREE DIRECTIONS

摘要

The invention relates to a plough for the 45 HP tractor with a coupling device adjustable on three directions, meant for ploughing carried out in any type of soil having a specific resistance of up to 90 N/cm, at adjustable working depths of up to 24 cm. According to the invention, the plough consists of a framework (1) on which some plough bodies (2 and 3) can be mounted together with some supports (4) fixed by means of some swinging bolts (5) and some shearing screws (6), a disc coulter (7) and a resting wheel (X), where the framework (1) consists of a traction bar (a) of square cross-section which is designed so that it can move by translation, in order to adjust a width (c) at a desired value along an axis (d-d) and fix it with a screw (e) for ensuring a normal working width of the first plough body (2), depending on the tractor wheel track while having the possibility of rotation in the horizontal plane to enlarge or narrow an angle ( α ) and of locking, by means of two adjusting screws (f and g), as to adjust the total working width, while, in the vertical plane it can be positioned at a preset distance (h) from the coupling point to the central tie rod located at a desired distance (i).
