Claims

[Scope of utility model registration request]

In an unloader that loads and unloads granular materials by grabbing them with a grab bucket, the lower end of the granular material fall prevention plate is provided on the unloader so that the lower end of the granular material fall prevention plate can be lifted up and down in the direction toward the loading and unloading side of the granular materials, and the lower end of the plate is provided with a hard bottom having a counterweight at the lower end. A side screen is suspended from the tip of the particulate matter fall prevention plate, and the lower end of the screen support frame is suspended at a position below the particulate matter fall prevention plate and can be lifted up and down in the direction of loading and unloading of the particulate matter. A hard lower screen provided on the prevention plate and having a counterweight at the lower end at the tip of the screen support frame is suspended by wrapping with the lower part of the upper screen, and the unloader, the particulate matter fall prevention plate, and the screen support frame. A device for preventing particulate matter from falling onto the sea surface, characterized in that the screen support frame is connected to a wire or a chain of a hoisting device fixed to the unloader.
