Description

  The present invention relates to a walking type electric power management machine including an electric drive type tilling shaft.

  When the conventional walking type management machine is moved on the road or the like, it is necessary to remove the resistance rod attached to the rear of the tilling shaft portion and attach the moving wheel to the attachment portion of the resistance rod. There was a problem that the work of attaching and detaching the rod and the moving wheel was complicated (see Patent Documents 1 and 2 below).

Further, when the conventional walking type management machine is moved on the road or the like, the gripping portion is pushed downward, and the tail wheel mounted instead of the resistance rod is grounded while lifting the tilling shaft portion upward. There is a need.
That is, in the conventional walking type management machine, the worker has to take a forward bending posture as compared with the time of tillage work when moving on the road or the like.

As a means to eliminate the trouble of attaching and detaching the resistance rod and the moving wheel, a rotating frame provided with a resistance rod on one end side and a tail wheel on the other end side can be rotated around a rotating shaft extending in the longitudinal direction of the machine body. Has been proposed (see Patent Document 3 below).
In this conventional walking type management machine, the rotary frame is fixed in a working posture so that the one end side provided with the resistance rod is positioned downward during the tilling work, and the tail wheel is provided during the movement. The rotating frame can be fixed in a moving posture so that the other end side is positioned below.

The walking type management machine with the rotating frame can simplify the switching work at the time of the plowing work and the movement, compared to the walking type management machine that needs to attach and remove the resistance rod and the moving wheel. It is necessary to change the posture of the rotating frame when switching between working and moving.
Moreover, the point that an operator must bend forward when moving on the road or the like is not different from the above-mentioned walking type management machine.
