This article relates to a mobile agricultural machine that can also be used as a transport vehicle.

[Conventional technology]

This type of mobile agricultural machine that can also be used as a transport vehicle has a structure that allows it to be used as a transport vehicle by removing the installed work equipment and using the work equipment mounting part as a loading platform. Rollers are provided at the front and rear of the working device so that the working device can be moved on the loading platform with little effort, and the running surface of the rollers and the working device can be placed and supported directly on the loading platform of the traveling vehicle body. Recesses into which the rollers are inserted are formed respectively. (For example, in the 1980s
(Refer to Publication No. 149932) [Problem to be solved by the invention] However, when starting to pull out the working device from the normal mounting position, a large force was required to make the rollers of the working device escape from the recessed part of the loading platform. .

An object of the present invention is to provide a mobile agricultural machine that can also be used as a transport vehicle, which allows the roller to escape from the recess and the working device to be pulled out with minimal effort.

[Means for solving problems]

The characteristic structure of the mobile agricultural machine that can also be used as a transport vehicle of the present invention is that it is equipped with a jack up member that can be forcibly adjusted up and down between the front and back of the roller, and a recess for the roller on the outside in the direction of pulling out the working equipment is formed to extend to the outer end of the loading platform. Its functions and effects are as follows.

[Effect]

In other words, the working device can be easily pushed up toward the pull-out direction by using the jack up member that can be forcibly adjusted up and down, and the recess for the roller located on the outside in the pull-out direction is formed to extend to the outer edge of the loading platform. Instead of pushing up the entire working device, the working device is simply pushed up so that only the inner roller in the drawing direction escapes from the recess, so the effort required for this purpose can be reduced compared to the conventional method.

[Effect of idea]

As a result, it has become possible for even one person to escape the roller from the recess and pull out the working device from its normal mounting position with less effort than before.
