A state in which two bucket-shaped lift arms i ... that scoop up the bale B are arranged in a row in front and back, and four roll bales B ... are scooped onto the vehicle body g by the respective bucket-shaped lift arms i ... In this case, the device is used to be transported to a desired place as it is.

[0005]

A conventional roll bale transporter A as described above is of the type shown in FIG.
In the configuration shown in the above, the roll bale B is easily deformed when loading and unloading the roll bale B onto the truck bed, and the roll bale B is transported while being loaded on the truck bed. The swinging of the bale B often causes damage to the film wrapped around the outer periphery of the roll bale B. In order to obtain a good quality silage, it is essential to repair the damaged portion of the wrap film. There is a problem that the work is troublesome.

[0006] In a wagon-type roll bale transporter A shown in FIG. 5, four roll bale B at a time are used.
Can be transported to a desired place without causing any damage during the transport process, but the number of lift arms i ... corresponding to the number of roll bales B ... which can be transported at one time is attached to the vehicle body g. There is a problem that the production cost increases due to the necessity of the provision.

Further, in the wagon-type roll bale transporter A, when the transported roll bale B is unloaded, the roll bale B is moved to the surface by the open rotation of the lift arm i. However, there is a problem that the film wrapped on the outer peripheral surface of the roll bale B is often damaged because the discharge is performed by rolling the roll bale.

The present invention has been made in order to solve the above-mentioned problem occurring in the conventional roll bale transporter A. Even if a small tractor having relatively low horsepower is used, the roll bale B ... Loading, transporting, and unloading are possible, and by simply incorporating one loading grip arm into the vehicle body, a large number of roll bales B can be loaded and transported at once, and transported It is an object of the present invention to provide a new means that allows a large number of roll bales B to be unloaded in a continuous state while being unloaded to a high place.
