Description
Technical Field
[0001] The utility model relates to the technical field of wall painting, in particular to a powder supply and spreader. Background Art
[0002] At present, wall painting is done manually. After the worker takes a roller brush and dips it in paint, he or she holds it up and paints on the wall. When painting some higher walls, a scaffold is needed, and the worker stands on it to paint the wall. During painting, the paint content of the roller brush dipped in paint will continue to change during the painting process, resulting in different thicknesses at each location. It needs to be polished several times later, which is very cumbersome. The painter needs to stand on the scaffold. Because the worker's attention is focused on the wall when painting, and indoor scaffolds generally do not have protective mechanisms, the worker may fall from the scaffold when moving, which poses a certain safety risk.
