This engineering project looks at Fabrication of metal panel door. Security of life and property cannot be overemphasized. Human beings need privacy in their various homes and offices which necessitate the need for doors among other security services. It has been a major challenge for the people to have doors of high quality and that are also durable at affordable prices by an average Nigerian. This project was done purposely to fabricate a metal panel door of high quality capable of giving maximum securities to life and properties at affordable prices. Locally available materials such as mild steel and cast of different sizes and shapes, forms and formats with a thickness of 1mm x 2mm were used with available indigenous technology without compromising the standard. The metal panel door consists of a frame unit, panel unit, stopper, hinges, and lock. Has its total dimension and weight to be 2135mm x 1220mm and 5639.8703N respectively. In other to prevent corrosion green anticorrosive (Glossy paint) was used. | Abstract
This engineering project looks at Design, construction and testing of beans threshing machine. The main objective of this project is to design construct and test of beans threshing machine at Bayero University Kano, Nigeria, to determine its performance and ease the drudgery problems associated with threshing of beans by a small scale farmers as well as large farmers. Evaluation was carried out with IT08K-150-27 soybeans variety at different level of moisture contents, 14.5%, 10.5% and 14% and at different drum speed 360 r/min, 466 r/min and 633 r/min with mass inputs of 1.5kg, 2.35kg and 2.0kg. the overall mean results obtained for performance indicators in terms of threshing efficiency are 95.3%, 97.0% and 92.46%,percntage of grain damage2.53%, 2.11% and 3.10% are and grain recovery are 98.1%, 98.37% and 98.09%. The evaluation results indicated the highest output of threshing efficiency of 97.0% at threshing speed 466rpm with an output of 120k/hr was achieve. The beans threshing machine is simple to operate and maintain simple without formal education. The unit cost of this threshing machine was 96,000(ninety six thousand naira only). | Abstract
This engineering project looks at the Fabrication of electrical popcorn machine. An electric popcorn machine is a machine that is used to pop com for human consumption. It uses electricity as its source of energy, transfer heat energy, that is used to rotate due to the convention of electrical energy from the source to mechanical energy in the motor, the stirrer turns the corn so that it will not burn. This project went as far as meeting most of the requirements of advancement in technology, which lead to making work easy and comfortable for the user. To be candid, the burden of mankind because of the existence of technology for this reasons, the government is expected to encourage the young technologist and engineers who have graduated and those who are yet to be graduated from school. By providing them with financial assistance, installation of functional and adequate equipment and facility various installations, competent and qualified personnel and in addition making education free for those who are not financially buoyant. By so doing, we will be boasting of technological advancement if we are ready to adopt indigenous technical experience rather than that of western one, which rather more expansion and at-time inappropriate. | Abstract
This engineering project looks at the Design and fabrication of a portable cassava grater. There is a need for the hygienic processing of cassava. Prevalent condition in the commercial grating area of this staple food shows susceptibility of food contamination. This project addresses the need for the development of a home-scale cassava grater where the materials, the tuber s of cassava being grated can be properly monitored. Some design considerations used in this project are the machine should be efficient during use in the household as well as moveable (portable) and Safety or easily operated. Another problem considered is that cassava produces a large amount of cyanogenic glycosides, so in selecting materials, for construction, adequate care must be taken not to use materials that cannot degrade/corrode easily due to the acidic content in cassava. The main component which is made from mild steel which consists of major parts namely, the mainframe which is constructed with angle iron which gives strength and rigidity to the war all matins, the hopper/s receptacle through which cassava is admitted into the machine for grating, the grating unit consist of the shaft, perforated mesh rolled sheet, circular disc and rival pins, the discharge unit which direct the flow of the grated cassava to a storage pit or receptacle, and the electric motor which is made from cast iron and winding horsepower of the machine. The capacity of the grater fabricated was 158kg/hr. The unit cost is #62,100 as against the #75,000 for the current grating unit in the market. | Abstract
Design and fabrication of corn sheller machine. A machine for corn shelling is highly and greatly needed for consistency of corn usage at local and international levels. With regard to this indispensable need, this improved corn shelling machine was designed to operate by removing or shelling 6.34kg of grains per hour and allowing the cob to drop off through a designed space. The process also allows the corn chaff to be blown by a fan attached below the cylindrical drum. The fan blade was intentionally made to rotate anticlockwise to achieve the direction of blowing out the corn chaff. The machine is power-driven by 0.75kw[1hp] electric motor through the means of belt drive. The shelling is done by a thresher contained in the chamber and driven by a pulley belt arrangement. The machine was tested to achieve the 6.34kg maize per hour capacity. It has an overall dimension of 890 ×470×180mm and a shaft speed of 1450 rpm. The machine was designed to achieve up to 75% efficiency.. | Abstract
This engineering project looks at The design and assembling of a tricycle engine (Paggio). In many developing countries, motorcycles and tricycle are increasingly becoming the common means of transport especially among low-income urban dwellers (urban poor) and many rural people. The high ownership and use of motorcycle in the urban areas in eastern Nigeria has come with its accompanying challenges like motorcycle accidents involving fatalities environmental and public health concerns from the emissions non-compliance to motor traffic regulations for instance helmet use is generally low in this region all of this which make a tricycle a more comfortable and affordable for commuter. The high incidence of tricycle ownership and use has also been contributing significantly to the betterment of many livelihoods of urban residents in Nigeria as a whole and at the instance Imo State for example. The increasing growth in the number of tricycles has come to solve the mobility needs of many urban residents in the light of poor and inadequate public transport system, poor road conditions particularly those leading into the peri- urban areas where many people reside as a result of urban sprawl. It also comes along with a host of opportunities including employment to tricycle mechanics and tricycle spare parts dealers, local revenue generating sources through taxes/levies on tricycle owners/riders as well as tricycle registration and licensing. The tricycle comprises body layout, front and rear longitudinal members, main floor unit, engine position, wheel bases, luggage space, the rear seat panel, boot floor, rear bumper, electrical and lighting system, chassis, ignition system, handle bar, fuel tank, brake and gear selector, engine access booth, two side mirrors, back and front tires, exhaust pipe and adjustable seat. Some of this which are not detail explain in this course of the work rather the paper work focuses on the Engine design layout and operation cycle of the engine, designs parameters (calculations) with engine parts and their major functions.. |
