  • Publication number: 20150029810
    Abstract: Truck-mounted tipping equipment for mixing and discharging concrete quickly includes an open tipping bucket shaped as a rectangular prism in the front and a semi-truncated cone in the rear that narrows towards a hydraulic discharge trap-door. The mixing and discharge mechanism has a spindle in an oblique position, to which helical fins have been welded serving as an endless screw. The diameter of these fins varies with the helix having a larger radius in the front (nearest to truck's cabin), and a reduced diameter rear part. The spindle keeps the concrete in continuous movement during transportation to prevent it from setting, and continuously moves the concrete towards the rear hydraulic trap-door. The trap-door remains closed until the concrete needs to be discharged. Once the majority of the total load is extracted, the tank is tipped to the rear to discharge the remaining concrete.

  • Patent number: 5772318
    Abstract: A portable hand-held concrete, mortar and gypsum mixer comprises a small gasoline powered implement having a drive shaft extending generally downward from the handles to a gear box. A transverse shaft driven by the drive shaft extends to either side of the gear box. Mounted on the transverse shaft are a plurality of blades shaped to thoroughly agitate and mix a combination of water and the ingredients for concrete, mortar, gypsum or similar heavy, hard to mix materials. Surrounding the blades are thin rings attached to the blades to form a round circumferential surface about the blades and thereby prevent the blades from directly contacting the mixing trough or other means of containing the mix. In the alternative, the plurality of blades may be shaped at their peripheries to form substantially continuous circular circumferences.

  • Patent number: 5718508
    Abstract: A self-cleaning mixer includes a cylindrical housing and a feedscrew extending longitudinally through the housing for mixing water and cement and conveying the slurry through the housing. A chute at the infeed end of the housing receives a batch of material and directs the material into the housing. The feedscrew turns on a hollow shaft including a plurality of outwardly directed nozzles along a portion of the length of the shaft. The housing includes a plurality of inwardly directed nozzles fed from a pair of manifolds. During a cleaning cycle, one of the manifolds is shut off, thereby increasing the water pressure in the other manifold and increasing the force of the spray to enhance cleaning. The housing is slightly inclined to provide gravity feed of slurry in addition to the feedscrew.

  • Patent number: 5609416
    Abstract: A small batch mixer particularly suited for preparing small quantities of mixture blends dry powdered material with an aggregate and a liquid. The ingredients may be cement, sand, and water. The batch mixer has two screw augers. The first auger feeds dry mix into an elongated mixing chamber of constant diameter. The second auger mixes the dry and liquid mix constituents, and conducts blended mixture to a discharge port located at the end of the elongated mixing chamber. The blade of the second auger is formed in three sections. In respective order, these sections include a first section wherein the blade is configured as a screw auger; a second section wherein the blade has intermittent gaps, thereby forming paddles pitched to urge the mixture onward to the third section; and a third section which, like the first section, includes a blade configured as a screw auger. The liquid is metered by a valve controlled in accordance with the feed rate of the solid constituents.
