Abstract

A rotary mixer has a mixing chamber with a rotor to reclaim the work surface. The rotary mixer has a supply container located on the frame adjacent to the front end thereof. The supply container contains an additive for mixing with the reclaimed work surface. A transport assembly connects the supply container to a distribution assembly. The distribution assembly is located in front of the mixing chamber and receives the additive from the transport assembly and deposits the additive on the work surface.

First claim

What is claimed is:

1. A rotary mixer comprising:
a frame defining a front end;
an operator station disposed on the frame;
a mixing chamber supported from the frame, the mixing chamber having a rotor to reclaim a work surface;
a supply container located on the frame in front of the mixing chamber, the supply container configured to contain an additive for mixing with the reclaimed work surface and having an opening in a bottom surface;
a transport assembly connecting the supply container to a distribution assembly wherein the transport assembly receives additive through the opening in the bottom surface; and
the distribution assembly located in front of the mixing chamber and at a distance from the supply container, the distribution assembly receiving the additive from the transport assembly and depositing the additive on the work surface.

2. The rotary mixer of claim 1 , further comprising a controller configured to measure and control an amount of the additive being deposited on the work surface.

3. The rotary mixer of claim 1 , wherein the transport assembly gravity feeds the additive from the supply container to the distribution assembly.

4. The rotary mixer of claim 1 , wherein the transport assembly includes a conveyor designed to move the additive from the supply container to the distribution assembly.

5. The rotary mixer of claim 4 further comprising a controller configured to control an amount of the additive moved from the supply container to the distribution assembly.

6. The rotary mixer of claim 1 , wherein the supply container is located in front of the operator station.

7. The rotary mixer of claim 1 , wherein the distribution assembly contains an auger to control an amount of the additive being deposited on the work surface.

8. The rotary mixer of claim 7 further comprising a controller configured to control the speed of the auger.

9. A rotary mixer comprising:
a frame defining a front end and a rear end;
an operator station disposed on the frame between the front end and the rear end thereof;
a set of ground engaging members disposed adjacent to each of the front end and the rear end of the frame;
a mixing chamber supported from the frame between the sets of ground engaging members disposed adjacent to the front end and the rear end of the frame, the mixing chamber having a rotor to reclaim a work surface;
a supply container located on the frame in front of the mixing chamber, the supply container configured to contain an additive for mixing with the reclaimed work surface and having an opening in a bottom surface;
a transport assembly connecting the supply container to a distribution assembly wherein the transport assembly receives additive through the opening in the bottom surface; and
the distribution assembly located in front of the mixing chamber and at a distance from the supply container, the distribution assembly receiving the additive from the transport assembly and depositing the additive on the work surface.

10. The rotary mixer of claim 9 further comprising a controller configured to measure and control an amount of the additive being deposited on the work surface.

11. The rotary mixer of claim 9 , wherein the transport assembly gravity feeds additive from the supply container to the distribution assembly.

12. The rotary mixer of claim 9 , wherein the transport assembly includes a conveyor designed to move additive from the supply container to the distribution assembly.

13. The rotary mixer of claim 12 further comprising a controller configured to control an amount of the additive moved from the supply container to the distribution assembly.

14. The rotary mixer of claim 9 , wherein the supply container is located in front of the operator station.

15. The rotary mixer of claim 9 , wherein the distribution assembly contains an auger to control an amount of the additive being deposited on the work surface.

16. The rotary mixer of claim 15 further comprising a controller configured to control the speed of the auger.
