Abstract

A mixing and delivery machine for flowable materials having on-site and towable mobility for mixing, hydrating, and delivering an admixture such as cementious mix, concrete, binder, graveled sand, mold sand and various other mixtures via an extended auger and elevatable hopper is used to facilitate both loading and releasing the hopper contents into the feed end of the auger. The auger is driven by a primemover and a wheel set on the machine facilitates the raising and lowering of the delivery end of the mixing auger.

Claims

1. A machine for mixing and conveying temporarily flowable solid materials to a delivery location comprising:

a base frame;

an elongated conveyor frame connected to said base frame;

a mixing conveyor mounted within said conveyor frame;

a material delivery hopper connected to said base frame;

an outlet located in a lower end of said delivery hopper for selectively admitting materials from the hopper into a proximal end of said conveyor; and

fluid delivery system connected to said base frame for admitting a fluid into said conveyor wherein an admixture of materials are deposited into a proximal end of said mixing conveyor by said hopper and fluid is added to said conveyor and the admixture of materials and fluid are combined within the conveyor to deliver a mixture;

2. A machine for mixing and conveying temporarily flowable solid materials to a delivery location as defined in claim 1 wherein said conveyor comprises:

a set of side walls and a base residing on a conveyor frame so as to define a trough-like containment for the materials and fluid;

a delivery port resident at the distal end of said mixing conveyor; and

a containment end wall located at the proximal end of said mixing conveyor.

a set of side walls and a base residing on a conveyor frame so as to define a trough-like containment for the materials and fluid;

a delivery port resident at the distal end of said mixing conveyor; and

a containment end wall located at the proximal end of said mixing conveyor.

3. A machine for mixing and conveying temporarily flowable solid materials to a delivery location as defined in claim 1 and further comprising:

means connected to said machine for selectively adding fluid to said admixture for mixing with particulate material within said mixing conveyor

4. A machine for mixing and conveying temporarily flowable solid materials to a delivery location as defined in claim 2 and further comprising:

lifting system for said hopper, said lifting system including at least two legs pivotally connected between said base frame and said hopper; and

means for pivoting said hopper from a lowered position with respect to said base to a parked end of said mixing conveyor.

5. A machine for mixing and conveying temporarily flowable solid materials to a delivery location as defined in claim 4 and further comprising:

at least a pair of movement wheels depending from of the base frame to facilitate movement of said machine to a desired deposit site.

6. A machine for mixing and conveying temporarily flowable solid materials to a delivery location as defined in claim 5 and further wherein said means for mixing comprises:

a variable speed direct drive connection between said base frame and said mixing conveyor.

7. A machine for mixing and conveying temporarily flowable solid materials to a delivery location as defined in claim 6 and further comprising:

said means of mixing materials includes a hydraulic motor.

8. A machine for mixing and conveying temporarily flowable solid materials to a delivery location as defined in claim 6 and further comprising:

said means for mixing materials includes an electric motor.

9. A machine for mixing and conveying temporarily flowable solid materials to a delivery location as defined in claim 5 and further comprising:

a drive connection between said means for mixing and said mixing conveyor comprising

a transmission system.

10. A machine for mixing and conveying temporarily flowable solid materials to a delivery location as defined in claim 5 and further comprising:

a stabilizer arm extending from the base frame and having a projection in the direction of pivotal travel of the hopper as defined by the support arms for stabilizing the hopper in a lowered condition.

11. A machine for mixing and conveying temporarily flowable solid materials to a delivery location as defined in claim 2 wherein said conveyor further comprises:

a drive shaft longitudinally positioned within said trough and journaled for rotation within said trough; and

auger blades mounted upon said drive shaft such that rotation of said drive shaft rotates said auger blades and concomitantly servers to advance particulates material within said trough from a proximal end beneath said hopper to a distal end and mix the particulate material with fluid within the trough as the auger advances the material and fluid within the trough.

12. A machine for mixing and conveying temporarily flowable solid materials to a delivery location as defined in claim 11 wherein:

said auger blade is divided into a plurality of independent sections serially connected along said drive shaft and the pitch of said auger blades are different in at least two sections of the auger.

13. A machine for mixing and conveying temporarily flowable solid materials to a delivery location as defined in claim 12 wherein:

the pitch increases in each section of the serially connected independent auger sections so that lateral transport of material decreases and mixing increases as material and fluid advance to the distal end of the auger.
