A concrete mixing carrier, comprising a vehicle chassis and a mixing drum provided thereon. A drum housing of the mixing drum is cubic, supported horizontally on the vehicle chassis, and able to form an unloading state where a front portion is higher and a rear portion is lower; the mixing drum forms a closed drum housing; a feed inlet and a discharge outlet are respectively provided on a rear end plate; a rotary inner drum formed by splicing movable blades is provided in the drum body, and adjacent movable blades have therebetween a movement margin for rotation; each strip-shaped movable blade is supported at both ends by paired rollers respectively; stirring blades overhang towards inside of the drum body, backs of back plates are provided with drive racks, and drive gears, mutually engaged with the drive racks, are provided at corresponding positions of the drum body using a supporting bracket.

Mobile mixing attachments, skidsteers with mobile mixing attachments, mobile mixing devices and related methods are provided. A mobile mixing attachment for use on a skid-steer can include a rotatable mixing drum having a body that forms an internal cavity and having a forward end and a bottom end. The mixing drum can include a mouth at the forward end of the body that provides access to the internal cavity of the mixing drum. The mobile mixing attachment can include a drum chassis configured to hold and rotate the mixing drum and an attachment plate secured to a rear portion of the drum chassis proximal to the bottom end of the body. The attachment plate configured to engage one or more attachment couplers on lift arms of a skid-steer. The mobile mixing device also comprises a scoop comprising a forward scooping lip and a rear loading end positioned in front of the mouth of the mixing drum. The scoop is secured to the drum chassis.

A portable mixing apparatus for mixing components is disclosed. The apparatus comprises a container for receiving components to be mixed, a frame for supporting the container in a first orientation for mixing components and a driving assembly couplable with the container for rotating the container. The frame comprises: a first handle for gripping with a first hand of a user, the first handle being disposed above a centre of mass of the portable mixing apparatus, when orientated in the first orientation, the first handle extending forwardly of the apparatus over the container; a second handle for gripping with a second hand of the user while the first hand grips the first handle, the second handle being disposed below the centre of mass of the portable mixing apparatus when orientated in the first orientation, the first and second handle being arranged to enable the user to carry the mixing apparatus and re-orientate the apparatus between the first orientation and a second orientation for emptying the components from the container.

A kneader includes a drum and a battery case. An intake port for taking in material to be kneaded is formed in the drum. An accommodation part is formed in the battery case. An opening for inserting a removable battery, or for retrieving the removable battery, is formed in the accommodation part. The battery case is retained in the kneader while oriented in a manner other than an orientation in which the opening faces the drum.

The invention provides compositions and methods directed to carbonation of a cement mix during mixing. The carbonation may be in a stationary mixer or a transportable mixer, such as a drum of a ready-mix truck.

The mixing machine is a motorized cement mixer that designed to mix cement in batches of less than 1 cubic foot. The mixing machine comprises a mixing bucket, a paddle insert, a motor, a drive system, a housing, and a control system. The mixing bucket is used to contain the cement or concrete mixture. The paddle insert is an insert designed to go into the mixing bucket. The paddle insert further comprises a plurality of paddles that are used to agitate the concrete mixture to insure efficient mixing. The motor and drive system are used to rotate the mixing bucket to efficiently mix the concrete mixture, and to prevent the concrete mixture from setting in the mixing bucket. The mixing machine comprises a mixing bucket, a paddle insert, a motor, a drive system, a housing, and a control system.
