Description

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. This is a structure that cannot be moved in the lateral direction.For example, work of a structure that is protruded from one of the wheels and the crawler belt of the traveling body to the one side position or the other side position of the traveling body. When the machine is not in operation, such as during transport or when not in use, the presence of a working machine that protrudes to the side may hinder small-turn travel, or the weight of the machine may be deviated to the side to reduce the driving operation of the traveling machine. It may cause instability, and depending on the work content of the working machine, it may be desirable to project it to one side position or the other side position of the traveling machine body, which reduces the flexibility of the working machine arrangement. By there has the disadvantage that it may cause a decrease in work efficiency.
