AUTO LOADING AND UNLOADING MOBILE CEMENT PROCESSING PLANT
The presented model will demonstrate a complete mobile cement processing plant which can be set up locally at a construction site, performing the functions of loading, weighing, mixing ingredients and finally unloading of cement. The technology in use at present involve cement carriers that only perform the mixing process and must be loaded with cement mix at off-site loading stations, in many cases at locations far from the construction site itself, at additional transport costs, consequently causing loss of time and negatively affecting productivity and general practicality. The equipment presented here proposes a solution to these problems, especially for small to medium size construction companies operating in locations where installing or access to a complete concrete processing plant is impractical.
Because it combines several normally separate equipments into one, it can be used in a small space, and to economic advantage, because of the smaller investment involved in purchasing, installing, operating and maintaining just one piece of equipment, rather than several. Not only will the equipment provide an increase in productivity and less total construction time, but upon job completion the unit can be immediately deployed elsewhere, which will make it extremely valuable for any construction company.
For a visual understanding of the appliance in question, refer to the attached illustration. FIGURE 1 - A complete view and layout of the unit. In reference to the illustration observe at the top the mechanical loader, and situated between the cement container and the operator cabin, the operator platform.
The loading system consists of a hydraulic oil container (1) hydraulic arm control levers (2) manipulated by the operator, working from a platform (5) which is accessible by ladder (6). The operator control panel will also provide a digital readout (15) of the weight of the ingredients. At the base of the loader (7) is a conventional adjustable support (3).
The loading mechanism, which is fixed on a base (8) comprises of a jointed hydraulic arm (9), (10) which moves by use of hydraulic pistons (11), (12), (13), (14) and the bucket (4). To the right, the cement mixing compartment (22) with hydraulic rotation speed limiter (21), (19) working with a hydraulic motor, powered by a hydraulic pump (16). Supply to the container (22) passes through water ducts (17) running along the lower part of the vehicle platform. Water levels are verified via hydrometer (20). When processing has ended, cement is collected at the tap (18).
To the lower right, dosage administrator (23) with support arms (24), (25) a digital scale (28) for measuring the ingredients, and the dosage opening (26) activated by pistons (27).
The dosage administrator (23) and the container (22) can be accessed via ladder (29) facilitating observation of the mixing process, controlled by the operator.
The implementation described above improves the economical and practical factors of cement fabrication from the use of a single mobile platform which combines a mechanical arm (4) a dosage administration system (28) with a digital scale (23) and a cement mixer
(22).
The dimensioning of capacity, weight and volume can vary, depending on the specific condition where a constructor plans to use the rig.
Where it differs from the present norm, is in its hydraulic, electronic and mechanical mechanisms with which it can load, weigh and process the ingredients required to make cement.
Locating the vehicle platform next to the raw materials, an operator working from the loader platform will be able to rotate the loading mechanism through 180° via the platform controls, enabling him to load materials onto the electronic scale. Water and ingredients are measured and passed on into the mixing compartment, the operator then initiates the mixing process, following which, the cement mix is ready to be unloaded at an appropriate location on the construction site, either by way of the hydraulic arm, or the tap.
