A mobile concrete mixing unit has an aggregate bin divided into two compartments by a water tank provided within the aggregate bin. A hydraulic reservoir is provided within the water tank in order to cool the hydraulic fluid within the hydraulic reservoir and warm the water within the water tank. The water tank also helps to keep the aggregate warm and flowable when used in low temperatures. A lower portion of the water tank includes sides that slope inwardly so that aggregate within the bin can drop freely onto a conveyor belt without bridging between the water tank and the sidewalls of the aggregate bin.

1. A mobile concrete mixing unit comprising: a mobile frame;an aggregate bin mounted to the mobile frame, the aggregate bin including a front wall, a rear wall, and sidewalls that span between the front and rear walls, each of the sidewalls sloping inwardly towards each other at a lower portion;a water tank located within the aggregate bin, the water tank spanning between the front wall and the rear wall, the water tank dividing an upper portion of the aggregate bin into a first storage area and a second storage area, the first and second storage areas being open at their lower ends, the water tank including a water outlet for dispensing water;a conveyor belt mounted to the mobile frame below the lower ends of the first and second storage areas;a hydraulics system for providing power to the mixing unit, the hydraulics system including a reservoir of hydraulic fluid, the reservoir of hydraulic fluid being located at least partially within the water tank;a cement bin mounted on the mobile frame; anda control system to control operation of the conveyor belt, hydraulics system, and water outlet to mix aggregate from the aggregate bin, cement from the cement bin, and water from the water tank to form a concrete mixture, whereby heat from the hydraulics system is transferred into water within the water tank to cool the hydraulics system and warm the water within the water tank. 2. The mobile concrete mixing unit of claim 1, wherein: a lower portion of the water tank slopes downwardly and inwardly to prevent aggregate within the aggregate bin from bridging. 3. The mobile concrete mixing unit of claim 2, further comprising a first baffle within the water tank. 4. The mobile concrete mixing unit of claim 3, wherein the first baffle comprises a first plate spanning across a width of the water tank, the first plate including a plurality of openings to permit flow of water through the first baffle. 5. The mobile concrete mixing unit of claim 4, further comprising a second baffle within the water tank spanning across the width of the water tank, the second baffle having a second plate including a second plurality of openings to permit flow of water through the second baffle. 6. The mobile concrete mixing unit of claim 2, further comprising a divider flange extending downwardly from the lower portion of the water tank towards the belt. 7. The mobile concrete mixing unit of claim 6, further comprising a resilient separator mounted to the divider flange and extending below the divider flange into close engagement with the belt. 8. The mobile concrete mixing unit of claim 1, wherein the reservoir of hydraulic fluid includes a hydraulic fluid inlet connected to an outlet of the hydraulics system and a hydraulic fluid outlet connected to a suction line of the hydraulics system; and wherein the reservoir of hydraulic fluid includes a hydraulic divider plate separating the hydraulic fluid inlet and the hydraulic fluid outlet to cause a flow of hydraulic fluid within the reservoir to thereby increase heat transfer between the hydraulic fluid within the reservoir and the water within the water tank. 9. The mobile concrete mixing unit of claim 1, further comprising: a support rod mounted between one of the sidewalls of the aggregate bin and a sidewall of the water tank. 10. The mobile concrete mixing unit of claim 9, wherein the mobile frame includes a plurality of ribs that support the aggregate bin on the mobile frame, and further wherein the support rod is aligned with one of the ribs. 11. The mobile concrete mixing unit of claim 1, wherein a portion of the water tank extends through the rear wall of the aggregate bin. 12. A mobile concrete mixing unit comprising: a mobile frame;an aggregate bin mounted to the mobile frame, the aggregate bin including a front wall, a rear wall, and sidewalls that span between the front and rear walls, each of the sidewalls sloping inwardly towards each other at a lower portion;a water tank located within the aggregate bin, the water tank spanning between the front wall and the rear wall, the water tank dividing an upper portion of the aggregate bin into a first storage area and a second storage area, the first and second storage areas being open at their lower ends, the water tank including a water outlet for dispensing water;a conveyor belt mounted on the mobile frame below the lower ends of the first and second storage areas;wherein a lower portion of the water tank slopes inwardly away from the sidewalls of the aggregate bin whereby a cavity between the lower portion of the water tank and the sidewalls of the aggregate bin prevents aggregate within the aggregate bin from bridging between the sidewalls of the aggregate bin and the lower portion of the water tank;a hydraulics system for providing power to the mixing unit, the hydraulics system including a reservoir of hydraulic fluid, the reservoir of hydraulic fluid being located within the water tank; anda control system to control operation of the conveyor belt, hydraulics system, and water outlet to mix aggregate from the aggregate bin, cement from a cement bin, and water from the water tank to form a concrete mixture, whereby heat from the hydraulic system is transferred into water within the water tank to cool the hydraulics system and warm the water within the water tank. 13. The mobile concrete mixing unit of claim 12, further comprising a first baffle within the water tank. 14. The mobile concrete mixing unit of claim 13, wherein the first baffle comprises a first plate spanning across a width of the water tank, the first plate including a plurality of openings to permit flow of water through the first baffle. 15. The mobile concrete mixing unit of claim 14, further comprising a second baffle within the water tank spanning across the width of the water tank, the second baffle having a second plate including a second plurality of opening to permit flow of water through the second baffle. 16. The mobile concrete mixing unit of claim 15, further comprising a divider flange extending downwardly from the lower portion of the water tank towards the belt. 17. The mobile concrete mixing unit of claim 16, further comprising a resilient separator mounted to the divider flange and extending below the divider flange into close engagement with the belt. 18. The mobile concrete mixing unit of claim 12, wherein the reservoir of hydraulic fluid includes a hydraulic fluid inlet connected to an outlet of the hydraulics system and a hydraulic fluid outlet connected to a suction line of the hydraulics system; and wherein the reservoir of hydraulic fluid includes a divider plate separating the hydraulic fluid inlet and the hydraulic fluid outlet to cause a flow of hydraulic fluid within the reservoir to thereby increase heat transfer between the hydraulic fluid within the reservoir and the water within the water tank. 19. The mobile concrete mixing unit of claim 12, further comprising: a support rod mounted between one of the sidewalls of the aggregate bin and a sidewall of the water tank. 20. The mobile concrete mixing unit of claim 19, wherein the mobile frame includes a plurality of ribs that support the aggregate bin on the mobile frame, and further wherein the support rod is aligned with one of the ribs.
