As described above, when a liquid spraying operation such as a chemical solution is performed using a power spraying machine instead of a powder spraying operation, a metering shutter attached to the bottom of the chemical tank is required. Instead, it is necessary to attach a chemical plate bottom plate as a blind plate for chemical solution spraying work, and it is necessary to constitute a chemical solution sucking section for locking the chemical solution outlet pipe to the chemical solution tank bottom plate.

However, in the method in which a chemical solution suction hole is additionally formed on the side surface substantially at the center of the chemical solution tank bottom plate to integrally form the cylindrical chemical solution suction portion, post-processing is performed after the formation of the cylindrical chemical solution suction portion. Therefore, a side hole must be provided as a chemical solution suction hole, which is extremely troublesome.

A method for holding the chemical suction nipple with a stay provided by welding to a chemical liquid tank bottom plate is as follows.
It is necessary to prepare special parts such as a chemical nipple and a stay in advance, and it is troublesome to manufacture the stay, such as welding the stay.

The present invention has been made in view of the above circumstances, and does not require any post-processing and special parts in the structure of the chemical solution sucking portion formed substantially at the center of the bottom plate of the chemical solution tank. It is an object to provide a tank bottom plate.
