The utility model discloses a kind of shot blasting machine paint spraying tool, including rack, the roller way is provided on the rack, it is characterized by: the roller way is formed by several rollers interval arrangement, each roller can rotate on rack for conveying steel plate;Each roller is equipped with several steel plate supports with adjustable distance between each other;The steel plate support includes hoop and support protrusion, and the opposite free end between the hoop is connected by bolt nut;The support protrusion is equipped with several, along hoop outer surface radial uniform arrangement, the support protrusion is detachably arranged outside hoop, the support protrusion supports steel plate, while reducing the contact area to steel plate.Detachable steel plate support is used, hoop is fixed by bolt nut, and it can be quickly disassembled and cleaned;After disassembly, smooth roll surface has no complex structure, paint is more easily removed, and maintenance cost is reduced.

The invention provides an underground water solid sampling device and a sampling method, relates to an underground water sampling technology, and particularly discloses a mounting shell, a displacement seat, a sectioning plate, a sealing plate, a driving structure, a buoyancy structure, a pushing structure, a coolant storage shell and an opening and closing structure. An independent sampling area is defined on a target water layer site, then freezing treatment is conducted on the sampling area through a cooling system composed of a coolant storage shell and a cooling cavity, a captured water sample is instantly frozen into solid ice columns, a driving structure controls a displacement base to carry the length of a sectioning plate extending out of a shell, and a sealing plate is driven to synchronously move; the volume of the sampling area can be flexibly adjusted, so that the requirements of different aquifer thicknesses or different sampling volumes can be met.
