초록 ▼

A pigmentation dispenser utilizes a hopper having two rotors therein, a first rotor above a second rotor. The second rotor moves the pigmentation material through an outlet opening and deposits it on a conveyor containing a concrete mix. The concrete mix and pigmentation material are then moved to a mixer which mixes them together. A cleanout is also in communication with the hopper and the second rotor can be reversed to move the pigmentation toward the cleanout.

대표청구항 ▼

What is claimed is: 1. Apparatus for adding pigmentation material to a concrete mixture, comprising: a hopper for containing the pigmentation material and having a bottom wall; a lower horizontal rotor with flighting positioned adjacent the bottom wall of the hopper and having opposite first and second ends; an upper horizontal rotor with flighting positioned in the hopper above the lower rotor; an outlet opening adjacent the first end of the lower rotor; a cleanout opening adjacent the second end of the lower rotor, the cleanout opening being normally closed to prevent pigmentation material from exiting through the cleanout opening; a drive system to rotate the upper and lower rotors; the drive system being adapted to rotate the lower rotor in opposite first and second directions for moving the pigmentation material towards the outlet and cleanout openings, respectively; a conveyor below the outlet opening for carrying the concrete mixture and receiving the pigmentation material discharged through the outlet opening; the conveyor having a discharge end; a concrete mixer adjacent the discharge end of the conveyor for receiving the concrete mixture and pigmentation material from the conveyor and for mixing the concrete mixture and pigmentation material together. 2. The apparatus of claim 1 wherein the upper rotor flighting is in the shape of a helical ribbon having an open center along the longitudinal axis thereof. 3. The apparatus of claim 2 wherein the upper rotor includes radial beater bars for mixing the pigmentation material during the rotation of the upper rotor. 4. The apparatus of claim 1 wherein the lower rotor flighting is in the shape of a helical ribbon having an open center along the longitudinal axis thereof. 5. The apparatus of claim 4 wherein an elongated mixing rod is within the open center and is attached to the lower rotor flighting. 6. The apparatus of claim 5 wherein the mixing rod is positioned off center from the longitudinal axis of the lower rotor. 7. The apparatus of claim 1 wherein the outlet opening includes an exit tube, the lower rotor extending within the exit tube. 8. The apparatus of claim 7 wherein the hopper includes a hopper chamber and the exit tube extends outwardly beyond the hopper chamber, the lower rotor having one portion extending within the exit tube and having a second portion within the hopper chamber and being exposed directly to the pigmentation material within the hopper chamber. 9. The apparatus of claim 1 wherein the upper rotor has a diameter larger than the lower rotor. 10. The apparatus of claim 1 wherein the upper rotor and the lower rotor both include helical ribbon flighting that has an elongated open center. 11. The apparatus of claim 10 wherein the lower rotor includes a longitudinal axis and an elongated rod is attached to the helical ribbon flighting off-center from the longitudinal axis. 12. The apparatus of claim 1 further comprising a plug removably mounted in the cleanout opening for normally closing the cleanout opening.
