US 4,060,225 A · Wheelbarrow with removable mixer

Abstract

A wheelbarrow mounting a container having upright side and end walls includes a generally U-shaped, upwardly opening cutout in one of the end walls. A mixing unit can be mounted to the wheelbarrow by placing a mounting plate of the unit over the cutout. The mixing unit comprises an elongate shaft protruding through the mounting plate into the container and means for driving the shaft. A mixing blade defined by axially spaced first and second arms which are angularly offset with respect to each other and attached to the shaft adjacent the mounting plate and adjacent a free shaft end, respectively, is also provided. The first arm of the blade extends radially away from the shaft and the second arm extends radially and axially away from the free shaft end while a generally longitudinally extending, twisted blade section interconnects free ends of the first and second arms.

Dependent claims

Apparatus for mixing and transporting a cementitious slurry comprising in combination:

a container including upwardly inclined sidewalls for receiving slurry materials including water and means mounting the container for movement over a support surface;
a mixing unit including a mixing blade being at least partially disposed in the container and drive means including a shaft for rotating the blade;
and means for removably mounting the mixing unit to and supporting the unit on an end wall of the container so that slurry materials in the container are intimately mixed by the blade when the drive means is actuated, the mounting means including a mounting plate to which the drive means is secured and through which the shaft extends, the plate including a U-shaped upper end defining a downwardly opening channel for engaging an upper edge of the end wall during the mixing operation;
whereby the slurry can be mixed in the container by temporarily positioning the mixing unit thereon and thereafter removing it for movement of the mixed slurry in the container to a point of use.

Apparatus for mixing and transporting a concrete slurry comprising in combination at least one wheelbarrow including a container for holding a quantity of the slurry during mixing and transport thereof, the container having elongate sides and an end wall;

a mixing unit for agitating and mixing a slurry in the container, the unit having an elongate mixing blade, a shaft mounting the blade, drive means for rotating the shaft about its axis, and means for mounting the mixing unit to the end wall so that the blade extends longitudinal of the container, the mounting means including a mounting plate to which the drive means is secured and through which the shaft extends, the plate including a U-shaped upper end defining a downwardly opening channel for engaging an upper edge of the end wall during the mixing operation, the blade having a curved configuration imparting to particles contacted by it while it rotates about the axis of the shaft a travel component in the direction of the container length so that the slurry circulates longitudinally in the container while the drive means is energized;
whereby the slurry can be mixed in the container with the mixing unit and the mixing unit can be removed therefrom for transport of the mixed slurry to a point of use while the mixing unit can be used to mix a slurry in another container.

A wheelbarrow for mixing and transporting concrete and like cementitious slurries comprising in combination:

an elongate container including relatively long sides and relatively short end walls interconnecting the sides, and means mounting the container for movement about a support surface, an end wall of the container including an upwardly open cutout extending from an uppermost edge of the end in a downward direction;
a mixing unit having a blade, drive means, and a shaft protruding from the drive means and mounting the blade for rotation with the shaft;
a mounting plate for mounting the unit to the container end wall, the mounting plate having a length and a width greater than the corresponding length and width of the cutout so as to completely overlie the cutout and close it, an upper edge of the mounting plate including a downwardly open U-shaped member disposed on the side of the mounting plate facing away from the blade;
means securing the mounting plate to the drive means and forming a gap between opposing sides of the drive means and the plate, respectively, the gap having a sufficient width to accommodate therein the container end wall;
a water supply conduit including a water shut-off valve attached to at least one of the drive units and the mounting plate for supplying water to the container when the mounting plate overlies the cutout;
the blade being defined by axially spaced first and second arms which are angularly offset with respect to each other and attached to the shaft adjacent the mounting plate and adjacent a free shaft end, respectively, the first arm extending radially away from the shaft and the second arm extending radially and axially away from the free shaft end, and a generally longitudinally extended, twisted blade section interconnecting free ends of the first and second arms;
whereby the slurry can be mixed in the container by placing the U-shaped member over the end so that the mounting plate overlies the cutout and the container end wall is disposed in the gap, whereby water required during the mixing operation is directly supplied to the materials in the container from the water conduit and the rotation of the blades imparts to the slurry in the container a circulatory motion generally parallel to the shaft and transverse to the direction of rotation of the blades.
