The invention discloses paint mixing equipment for construction machinery. The equipment structurally comprises a paint mixing device, a paint film forming solution adding port, an auxiliary film forming matter adding port, a film matter adding port, a display screen, control buttons, an observing window, rotating shaft plates, a taking side plate, a support pallet and a handle, wherein the paintfilm forming solution adding port, the auxiliary film forming matter adding port and the film matter adding port are formed in the upper end of the paint mixing device; the film matter adding port isformed in the right side of the auxiliary film forming matter adding port, and the paint film forming solution adding port is formed in the left side of the auxiliary film forming matter adding port.When all ingredients enter a stirring chamber, the ingredients are stirred by a stirring motor, the mixture is poured into a paint finished product integration box by guide wheels after stirring is completed, the paint finished product integration box is opened up through the handle, a product is taken out, paint preparation is performed mechanically instead of manually, the artificial labor is greatly saved, and the productivity is also greatly improved.
