DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The house management work machine 1 is provided with front wheels 4 and 4 and rear wheels 5 and 5 on both front and rear sides and left and right sides of a traveling chassis 3 which is a traveling device 2. And a work device 6 for performing tillage, medium tillage, fertilization, and the like, which are various types of work, and the house management work machine 1 will be illustrated and described.

A pair of front wheels 4, 4 and a pair of rear wheels 5, 5 arranged below the traveling chassis 3 are connected to respective wheel motors 7 in an interlocking manner, and are also connected to the traveling direction. A steering angle sensor 8 is provided for pivotally supporting the vehicle so as to be able to turn freely, and for detecting a steering angle for separately controlling the front and rear wheels 4 and 5. A battery 9 as a power source is provided between the front and rear wheels 4 and 5 on the lower side of the steering chassis 3 so as to be able to move up and down. The battery 9 is a battery motor 10 provided on the upper side of the traveling chassis 3. In connection with the forward and reverse rotation of, the construction is such that it can move up and down to the field scene via the connection shafts 11 on both the left and right sides.

In conjunction with the forward and reverse rotation of the battery motor 10, when the battery 9 is lowered to the field scene via the rotating device 12, the traveling platform 3 and the working device 6 are rotated left and right. It has a flexible configuration. The working device 6 for performing various operations in the house, such as tillage, medium tillage, and fertilization.
Is detachably provided at the rear of the traveling chassis 3,
The transmission mechanism 13a in the transmission case 13 provided on the upper side of
The transmission case 13 is configured to be rotationally driven by being linked to a work motor 14 provided above the transmission case 13. The working device 6 is configured to be rotationally driven via the PTO shaft 13b of the transmission mechanism 13a.

The power source for each of the motors 7, 10, 14 is a battery 9. By using the battery 9, the house management work machine 1 can be used as a machine that does not generate exhaust gas, thereby ensuring safety of work. And environmental considerations.
