Detailed description of the invention
The foregoing objects of the present invention are accomplished and the problems and shortcomings associated with the prior art, techniques and approaches are overcome by the present invention as described below in the preferred embodiments.
The present invention provides a mobile batching plant which is easy to transport. Further, the mobile batching plant decreases transport, and labour cost.

The present invention is illustrated with reference to the accompanying drawings, throughout which reference numbers indicate corresponding parts in the various figures. These reference numbers are shown in bracket in the following description.
Referring now to figure 2-4, there is shown a mobile batching plant in accordance with the present invention. Specifically, figure 2-4 shows the mobile batching plant (100). The mobile batching plant (100) includes a chassis assembly (1), an aggregate weighing hopper assembly (2), an aggregate storage hopper assembly (3), a panel assembly (4), an aggregate weighing conveyor assembly (5), a skip track assembly (6), at least one skip bucket assembly (7), at least one pan mixer assembly (8), a weighing screw conveyor (9), a cement feeding screw conveyor assembly (10), a middle stand (11), a cement feeding hopper (12), at least one concrete discharge chute (13) and a screw conveyor mobility bracket (14).
The chassis assembly (1) provides a base structure of the mobile batching plant (100). Specifically, the chassis assembly (1) is a fabricated unit which provides support for all the components of the batching plant (100). In an embodiment, the chassis assembly (1) is provided with a plurality of wheels (not numbered) for easy movement thereof. In another embodiment, a towing unit (not shown) is provided which helps in pulling and steering of the batching plant (100), whereby the chassis assembly (1) supports the mobile batching plant (100) for toeing thereof.
The aggregate weighing hopper assembly (2) provides for aggregate, for example, sand, cement, water and admixtures weighing. The aggregate storage hopper assembly (3) provides for storage of the aggregates and the panels assembly (4) provides for increasing the storage capacity of aggregate. The aggregate weighing hopper assembly (2), aggregate storage hopper assembly (3), and the panels

assembly (4) are removably secured to each other and are mounted on the chassis assembly (1).
Further, the weighing screw conveyor (9) collects, weights and discharge cement and fly ash into the pan mixer assembly (8), and the skip bucket assembly (7) receives aggregate material from the aggregate weighing conveyor assembly (5) and discharges the aggregate material into the pan mixer assembly (8). Furthermore, the skip track assembly (6) allows the skip bucket assembly (7) to travel thereon and provides support therefor. In an embodiment, the skip bucket assembly (7) travels over the skip track assembly (6), which is powered by an electric motor (not shown).
The cement feeding screw conveyer assembly (10) feeds cement from the aggregate weighing hopper assembly (2) to the weighing screw conveyor (9) as shown in figure 5. The cement screw conveyer assembly (10) is provided with a pivot (not shown) at the top, middle and bottom portions thereof. Further, a middle stand (11) is provided for supporting the cement feeding screw conveyor assembly (10).
