Abstract
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.
Claims20
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;
- and
- a 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.

- 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;
- and
- a 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.
