2. Description of the Related Art A chemical tank for storing a chemical or the like to be sprayed on a field is sometimes mounted on a (small) self-propelled vehicle for transportation.

In a conventional structure for mounting a chemical tank on a self-propelled vehicle, a bolt has a head portion embedded in a lower wall of the chemical tank and a shaft protruding downward from a lower wall of the chemical tank. On the other hand, the frame of the self-propelled vehicle is provided with an insertion hole through which the shaft of the bolt is inserted vertically from above to below. When the chemical tank is mounted on a self-propelled vehicle, a plurality of workers lift the chemical tank (generally, the capacity is 300 to 1,000 liters and the weight is large), while the chemical tank is self-propelled. Carry it on the frame of the vehicle, lower the chemical tank so that the shaft of the bolt is inserted into the insertion hole on the frame side, place the chemical tank on the frame, and install the bolt shaft from under the insertion hole. The nut is screwed into the part to fix the chemical liquid tank to the frame. When removing the chemical tank from the self-propelled vehicle, the procedure is reversed.

[0004]

[Problems to be Solved by the Invention] Mounting and unloading a conventional chemical solution tank on a self-propelled vehicle requires a large number of workers and also requires time and effort.

An object of the present invention is to provide a tank device for mounting on a traveling vehicle, which can save labor, labor and efficiency in loading and unloading operations on the traveling vehicle.
