Claims

[Scope of utility model registration request]

The work device attachment hitch 10 of the management machine main body 9 and the attachment part 11 for connecting the work device 7 to the management machine main body,
A management machine configured to be able to be connected and detached by fitting horizontal pins 12 and 13 attached to the upper and lower parts of the mounting part 11 into recesses 14 and 15 formed in the upper and lower parts of the hitch 10. In this working device mounting structure, the upper recess 14 is formed in an upwardly open shape, and the axis P of the upper pin 12 is set in a state in which the upper pin 12 is fitted into the upper recess 14. The lower pin 13 is formed in the lower recess 15 with an open part facing in the direction of the circular arc locus L as the center and toward the working device side, and is fitted into the lower recess 15.
The locking mechanism A is provided with a locking mechanism A that can prevent the machine from moving toward the work equipment side, and this locking mechanism A has an axis in the longitudinal direction of the machine body, and has a rotational position that prevents movement toward the work equipment side. A shaft 16 is provided on the hitch 10, and a pin locking tongue 17 and an operating lever 18 are attached to the rotating shaft 16 so that both 17 and 18 rotate together, and the operating lever 18 is swung. Due to this, the tongue piece 17 is attached to the pin 13 on the lower side.
A working device mounting structure for a management machine configured to switch between a position that interferes with the arc locus L and a position that does not interfere with the arc locus L in the actual swing region.
