INTRODUCTION

Wheel Powered Cart Brush. We ended taking up this study without hesitation and doubt because we believed that this would be a great deal and sure cooperate to improve the principle and ways of cleaning surroundings. As engineering students studying in this university, supposedly, we are concerned that our knowledge and learnings can be use in good and helpful ways especially with having a beautiful surroundings and clean and green environment. One of the purposes why we have engineers and students studying engineering is to bring help in every, even in a small ways to improved and developed having an easy way of living and to ease every individual’s work. Having good and clean surroundings, we have utilities in our school. They stand to maintain the orderliness and cleanliness of our surroundings. One of these is cleaning the roads where we usually find them working or whether they’re using machinery but those which are consumed more energy and takes many times to do the work. In addition, those machines involve financial negotiations. In places to places, we can see that this situation happens not only in our school which workers uses pressurized water to cleanse paths that are rotten by dirt. We all knows that job will be easier if we have proper machines designed to this kind of work that will help the workers to ease and to give more efficient way of cleaning. In addition, it will take the workers tedious and hardworking job. It will also take less energy and less water consuming if we make this kind of machinery.

Due to mechanical work of the said project, we can’t make sure that smoke and noise will not be distraction to the students for it is not working with motor compared to grass cutting machine, and the importance of the said project is it will make the job of the workers easier and less time comparing to other machine that they used this time. Especially in Southern Luzon State University that some pathways are rotten, it will be a good advantage that we have this kind of machine and it will be a good deal if the study of development and improvement of this project will be continued.

Background of the Study Looking at the general overview of this topic research, the idea of the thesis begins when we are walking outside the admin building and saw one of the utility of our school uses pressurized water to clean area that is rotten. We saw that the machine consumed more water rather than the work to be done. These scenario bring us to an idea to improved and bring there working into easier way. This topic may not be as wider as the other topics but it will have a big contribution to our community with problem to slippery outdoors especially during rainy season. In area with so many people, this problem is common but it can be minimized with the help of Wheel Powered Cart Brush. The construction of the said machine use rotating brush. This would be the main cleaning part and placed in front of the machine. The specialty of this machine is for outdoors so the brush needed will designed for hard operating process. In addition, this machine will be more efficient than actual cleaning or cleaning using pressurized water

from the pump. It will be easy to recommend using this machine for ground cleaning operation for it has more advantages than other operation. Having clean surroundings is important for it helps us to have a good quality of living. The CIRI once said; “It is imperative that the focus be on ‘cleaning green,’ that is cleaning first, cleaning for health and hygiene, as well as cleaning in an environmentally preferable manner.” - Cleaning Industry Research Institute (CIRI)

Objectives of the Study The study generally aimed to design with improving way of cleaning and help the workers to have an efficient and easier ways to this job using Wheel Powered Cart Brush. Specifically, this study intended to meet the following objectives: 1. To design and fabricate a pathways cleaning machine powered by wheel. 2. To compare the performance of wheel powered cart brush to pressurized washer from the pump in terms of: 2.1. Time 2.2. Efficiency 2.3. Human effort 3. To minimized the use of water from pressurized water from the pump and maximized the conservation of energy using wheel powered cart brush.

Significance of the Study

Considering that science and technology plays a very important role in a society, the findings of this study will rebound in benefit of individuals. This technical study intended to design a machine that will serve as a substitute to old way of ground cleaning operation and to usual pressurized water used as a machinery. This research study entitled “Wheel Powered Cart Brush” will be beneficial to the workers as it will help them to ease their job and will give a more efficient way of cleaning. It will also require a lesser effort compared to actual way cleaning and with using of pressurized washer that consumed more water. In addition, the time consumed in operation will decrease because the machine will fasten the job. For the researcher, this study means applying their knowledge in the field of machine design. This study could also be a good start for the researchers to introduce an alternative, advanced way of ground cleaning operation in a more efficient and faster way. For the readers or future researchers, this study will serve as reference material for material for additional knowledge and valuable information not only in their study but also in conducting researches about environmental cleanliness and orderliness, thus, ground cleaning operation.

Scope and Limitation The proposed research study primarily focused on improvement and advancement of ground cleaning operation. Design calculations and assumptions were made as a consideration to come up with realistic and effective design for more favorable results and quality output.

The study concentrated in determining the effectiveness of improved way of cleaning compared to actual way and using of pressurized washer. Moreover, the machine is design for ground surface cleaning purposes only and since it is design with wheels, it may not reach the corners of the walls but with hoping for continuation of the study, we’re sure these limits will be eliminated. This study limits the machine in cleaning the surfaces that are not concrete and not flatten in order to protect the machine from destruction. The machine designed for flat surfaces only since the wheels are not adjustable. In addition, since the machine is not automatic, it will require a manual stirring from the workers but with this method, it can help the machine to clean the surface accurately and without exception of areas.

Definition of Terms All the terms below are list of the words that tackled during the research. They are defined operationally and how they were being used in the study. 

Brush, plastic: a part of the machine which act as the floor cleaner moved by shaft connected to the wheel shaft via chains and sprocket.



Cart: a usually two or four wheeled vehicle moved by pull or push force.



Chain and sprocket: the acting mechanism or the heart of the machine and make it do the job.



Chassis: is the internal frame work or a construction of metals standing as the body of the machine and support the man-made object.



Grime: a general term refers to dirt that covers the surface. Examples are moss, algae, liverwort, lichen, etc.



Pillow Block: is a pedestal used to provide support for a rotating shaft with the help of compatible bearings & various accessories.



Prototype: is a first, typical or preliminary model of something, especially a machine, from which other forms are developed or copied.



Shaft is a long, narrow part or section forming the handle of a tool or club, the body of a spear or arrow, or a similar implement.



Static Friction: is a force that keeps an object at rest. It must be overcome to start moving the object.



Wheel: is a circular object that revolves on an axle and is fixed below a vehicle or other object to enable it to move easily over the ground.
