Description

DETAILED DESCRIPTION OF THE INVENTION Industrial field of application The present invention relates to a traveling device of a mobile agricultural machine and can be used for a reaper and the like.

Problems to be solved by the conventional technology and the invention In a work machine having a small number of reaping strips of a reaper, it is suitable for work to make the traveling wheel width narrower than the number of reaping strips or the reaping width. The position of the center of gravity of the vehicle body with respect to the wheels must be prevented from changing to the left or right depending on whether the vehicle body is used as a single-wheel configuration with a single wheel or as a two-wheel configuration for left and right two-wheeled vehicles.

For this reason, the present invention facilitates the change to both of these forms by replacing both the single-wheel transmission case for a single wheel and the two-wheel transmission case (8) for left and right two wheels on the vehicle body side. At the same time, it also facilitates the extraction of power to the accessory working device.

Means for Solving the Problems This invention is provided with protruding both ends of a transmission shaft 14 on both left and right sides of a transmission case 2 in which a transmission device 1 for transmitting to a traveling wheel is installed, and one side of this transmission case 2 is provided. , A two-wheel transmission case 8 axially mounting a drive shaft 4 and a pair of left and right wheels 7, 7 transmitted from the drive shaft 4 via axles 27, 28.
Of the shaft end 3R side with respect to the transmission shaft 14
The wheels 7 and 7 are provided so as to transmit and rotate from 3R through the drive shaft 4, and the shaft end 5 side with respect to the drive shaft 4 serves as a power take-out shaft portion for an accessory device.
On the other side, there is an input shaft 9 on one side in the left-right direction and a one-wheel transmission case 11 mounted on one side in the left-right direction, which is transmitted from the input shaft 9, and a transmission shaft 14 of the transmission case 2. Is provided so as to be connectable to the shaft end 3L side with respect to the shaft end 3L so as to transmit and rotate the wheel 10 via the input shaft 9 and the shaft end 3R side with respect to the transmission shaft 14 serves as a power take-out shaft portion for an accessory device. The traveling device for a mobile agricultural machine is configured as described above.

Action and effect of the invention When the transmission device (1) is transmitted by driving the engine of the vehicle body, the transmission shaft 14 of the transmission case 2 is transmission-rotated.
