A mixing device comprises a hollow drum formed by a shell of substantially constant thickness and defining generally a body of revolution, preferably cylindrical, spheroidal or ellipsoidal. The drum includes internal vanes which are defined by corresponding grooves extending inwardly from the external surface of the drum, each groove having detachably positioned therein a comb of spikes. An opening is provided in one axial end of the drum by means of which the interior of the drum can be filled with and emptied of material. A handle is pivotally connected to the drum so that the drum is rollable along a supporting surface and rotatable relative to the handle about an axis coincident with the axis of said body of revolution during which rolling the vanes agitate the material within the drum. A spraying attachment can also be provided which includes a sprayer head connected to the interior of the drum by way of a pipe.
A mixing device comprising a hollow drum formed by a shell of substantially constant thickness and defining generally a body of revolution about a first axis, a handle pivotally connected to said drum so that said drum is rollable along a supporting surface and rotatable relative to said handle, means defining an opening in said drum by means of which the interior of said drum can be filled with and emptied of a material to be mixed therein, and internal axially extending vanes in said drum for agitating said material when said drum is rolled along said supporting surface, each said internal vane being defined by a corresponding groove which extends inwardly from the external surface of said drum, each groove having detachably positioned therein a comb of spikes which project outwardly of said drum away from said first axis.
