DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example,
The present invention relates to a working machine connecting device used when connecting various agricultural and horticultural working machines such as a transport working machine and an aerial working machine.

[0002]

2. Description of the Related Art Conventionally, as a working machine connecting device of this kind, a working vehicle is pivotally mounted on the left and right lower portions of a rear portion of a tractor as a traveling machine, and is vertically moved by a pair of left and right hydraulic arms of the traveling machine via respective suspension arms. There is known a so-called three-point link type coupling mechanism including a pair of left and right lower links movably provided and an upper link pivotally mounted on an upper rear portion of the traveling body.

[0003] Various working machines are pivotally connected to the respective ends of a pair of lower links and upper links in a three-point support state, and each of the working machines is pivotally moved up and down by a pair of left and right hydraulic arms of the traveling machine. The work machine body is vertically movably connected by vertically swinging the lower link via the suspension arm.

[0004]

However, in the case of the above-mentioned conventional structure, although it is possible to cope with the work contents and operation conditions of the various working machines by moving the various working machines up and down, it is possible to cope with the traveling direction of the traveling machine. Therefore, for example, in a working machine having a structure that is protruded from a position where wheels and crawler belts of the traveling body are disposed to a side position of the traveling body, During non-operation, such as when the vehicle is not in use or when it is not in use, the presence of a working machine that protrudes laterally may hinder small-turn running, or may cause instability in the driving operation of the traveling machine due to the weight offset laterally. Also, for example, in a rowing machine for forming and repairing a row, as shown in FIG. 11, a rowing work mechanism D is protrudingly arranged at one side position of the running body C, and the running body C is indicated by an arrow in the figure. Turn in the direction Traveling forward while, because that would perform Seiaze work ridge W by Seiaze working mechanism D, the traveling machine body C
An unaligned ridge work part B as an unworked part from the front part of the ridge work mechanism D to the work site is inevitably generated.
Since the unaligned ridge work portion B is left to an artificial work, there is a disadvantage that the work efficiency may be reduced accordingly.
