Shortly explanation of each part as follow. We are developed agriculture Fertilizer mechanical project. This project provides farmer three needs solution crop fertilizing. Shortly explanation of each part as follow. An understanding of soil chemical properties is important because of their effect on nutrient Availability to plants. Also, these properties may usually be favorably altered with the use of lime and/or fertilizer materials. Many plants need 18 elements (see Table 1) for normal growth and completion of their life cycle. These elements are called the essential plant nutrients. Soil amendments containing the essential plant nutrients or having the effect of favorably changing the soil chemistry have been developed and used to enhance plant nutrition. These amendments are our lime and fertilizer materials. With the development of these modern lime and fertilizer materials, as well as equipment for handling and application, amending soil chemical properties became a cheap and easily accomplished task relative to the high returns often achieved. Soil testing developed as a means for answering questions about need for a particular amendment (status of the soil's fertility) and uncertainty about how much to add.

B.6 1,2,3,4Student at Department of Mechanical Engineering, University of Pune, SND COE & RC, Yeola, Dist. Nasik, India [1] A method was generated to spread the fertilizer uniformly over a fallow land by dropping the fertilizer over the impeller disc. The system consists of a three wheels, two at the front and one at the back. These two wheels at the front are used to impel the fertilizer. The two hoppers are used to store the fertilizer; these hoppers are placed at some height from the wheel axle so that the fertilizer falls on to the impeller. The hopper is provided with flow control mechanism. In fertilization, the flow maintenance is necessary. Generally every crop should get sufficient amount of fertilizer. This condition is satisfied by Spring Mechanism. In normal conditions spring is not in tension and hopper is closed. As operator apply tension on the spring, controlling plate moves backward and hopper is open. Below this system there is an impeller. It is mounted on output shaft. Hooper opens on Impeller eccentrically and due to centrifugal action fertilizer spreads in the farm. This high value of centrifugal force is generated by the help of proper gear reduction ratio. The gears are coupled to the shaft of wheel. With this machine, percentage reduction in time required for Fertilization was observed to be 50% and reduction in labor cost as compared to conventional method was 80%.

Vignesh.B1 NavaneethaKrishnan.M2 Sethuraman.N3 1,2Student 3Associate Professor 1,2,3Department of Mechanical Engineering 1,2,3IFET College of Engineering, Villupuram, India [3] A method was generated to spread the fertilizer automatically over the agricultural land by dropping the fertilizer over the impeller disc. A 25cc engine is used to rotate impeller disc in which the fertilizer drains and spreads from hopper where it is introduced. In tractor mounted or manual system they carry four and three wheels respectively. But here two wheels are used in which the bigger front wheel is connected to engine through supporting wheel can be adjustable. The speed of wheel is varied by control lever connected through a cable. In this the fertilizer spreads only in front side of impeller while its back side 180 is covered. The size and width of the fertilizer is reduced to make it less weight and suitable for multi crops. From this method the cost fertilizer spreader is reduced by 50%.

In Feb 2015, Narode R.R, Sonawane A.B, Mahale R.R, Nisal S.S, Chaudhari S.S, Bhane A.B proposed “Manually Operated Fertilizer Spreader”. [4] A method was generated to spread the fertilizer uniformly over a fallow land by dropping the fertilizer over the impeller disc. The system consists of a three heels, two at the front and one at the back. These two wheels at the front are used to impel the fertilizer. The two hoppers are castoff to supply the fertilizer. These hoppers are tie up at certain height from the wheel axle so that the fertilizer drops on to the impeller. The hopper is on condition that with flow control contrivance. In fertilization, the flow maintenance is indispensable. In general every crop ought to get sufficient amount of fertilizer. This condition is gratified by Spring Mechanism. In ordinary conditions spring is not in pressure and hopper is locked. As operator apply pressure on the spring, controlling plate moves backward and hopper is open. Beneath this system there is an impeller. It is astride on output shaft. Hooper opens on Impeller bizarrely and due to centrifugal action fertilizer spreads in the farm. In February 2016, S.Meivel, Dr.R.Maguteeswaren, N.Gandhiraj, G.Srinivasan proposed “Quadcopter UAV Based Fertilizer and Pesticide Spraying System”. The quadcopter is cost in effect substitute to extraordinary cost standard rotorcrafts. UAVs are briskly forthcoming routine for cultivation, production and protection progressions.

2.2 PROBLEM DEFINITION In recent days it has been found that farmers are unable to gain more crop production by use of conventional agriculture methods and also each farmer which have less farm area. So there is big need for the development of farming equipment’s for compensating these drawbacks. It is well known that by using farm equipments farmers yield more crop productions which ultimately have an impact on national economy. It gives prior need of development of agro equipment in field of agriculture. As we can see today the major problem faced by farmers is shortage of labour and also time required for fertilization is more. In order to solve this problem, it was proposed to manufacture a fertilizer spreader machine which will be more economical than other spreader machines available in market for the large farm owner. So, farmers can work more easy and functional.

AGRICULTURE FERTILIZER FEEDING MACHINE

In a system design we mainly concentrated on the following parameters, system selection based on physical constraints. While selecting any machine it is going to be used in large scale industry or small scale industry in our case it is to be used by small scale industries. So space is a major constrain. The mechanical design has directly norms with the system design. Hence the foremost job is to control the physical parameter, so that the distinction obtained after mechanical design can be well fitted into that. In system design we mainly concentrated on the following parameters. 1. Arrangement of various components: Keeping into view the space restrictions the components should be laid such that their easy removal or servicing is possible. More over every component should be easily seen none should be hidden. Every possible space is utilized in component arrangement. 3.1 Method of Manufacturing Process This chapter will cover the details explanation of methodology that is being used to make this project complete and working well.

Manufacturing involves making products from raw materials by various processes or operations. Manufacturing is generally a complex activity, involving people who have a board range of disciplines and skills and wide verity of Machine, equipment, and tooling with various levels of automation, including computers, robots and material handling equipment or devices. Manufacturing is the process of converting the raw material, components or parts into the finished product that meet a customer’s expectations or specifications. 8

AGRICULTURE FERTILIZER FEEDING MACHINE

Manufacturing process are the steps through which the raw materials are transformed into which the design is made. These materials are then modified through manufacturing process to become the required part. Manufacturing processes can include treating (such as heat treating or coating)’ Machine or reshaping the material. The manufacturing process can also include tests and checks for quality assurance during or after the manufacturing and planning the production process prior to manufacturing. Manufacturing is the production of merchandise for use or sale using labor, Machine tools, chemical & biological processing or formulation. The term may refer to a range of human activity from handicraft high tech, but it most commonly applied to the industrial production, in which the raw material are transformed into finished goods on a large or small scale. Such finished goods may be used for manufacturing other, more complex products, such as aircrafts, household appliances or automobiles, or sold to wholesaler, who in turn sells them to retailers, who then sell to end users (customers). The manufacturing sector is closely connected with engineering and industrial design. 3.2.3 Performed operations: In our project we performed some manufacturing operating operations so as to complete our project and to perform those operations we used followings some manufacturing processes they are: 1. Cutting. 2. Drilling. 3. Grinding. 4. Tapping. 5. Welding. 6. Finishing. 7. Hammering. 3.3.4 Cutting Operation:-

AGRICULTURE FERTILIZER FEEDING MACHINE

Cutting operation is done for to cut the pipes for making an cylinder and condenser is a required dimensions from it. The power hacksaw is used to cutting purpose of pipe and also we required cutting operation through power hacksaw for cutting of air receiver material so as to make receiver and condenser. The material of air receiver and condenser is mild steel. So it does required additional stress for cutting operation.

Fig.3.3.1 Cutting

3.3.6 Drilling operation:Drilling is a cutting process that uses a drill-bit to cut or enlarge a hole of circular cross section in solid materials. The drill bit is a rotary cutting tool, often multipoint. The bit is passes against the work piece and rotated inside the work piece so as to produce a drill on it. The most important type of drill is the twist droll. In our project we performed a drill operation on end surface plate which is used to connect the air connection, pressure gauge, regulating valve inside the cylinder. The drill is required to allow filter air to the air conditioning effect. 3.3.7 Grinding operation:10

AGRICULTURE FERTILIZER FEEDING MACHINE

Grinding may be defined as the act of shaping or wearing down a surface or sharpening an edge by means of the cutting action of thousands of abrasive grains on the surface of the grinding wheel. Excessive grinding shortens the useful life of a tool. Taping is the manufacturing process used in produce the thread. Threading is the process of creating a screw thread.

AGRICULTURE FERTILIZER FEEDING MACHINE

Welding Arc welding is one of several fusion processes for joining metals. By applying intense heat, metal at the joint between two parts is melted and caused to intermix directly, or more commonly, with an intermediate molten filler metal. Upon cooling and solidification, a metallurgical bond is created. Since the joining is an intermixture of metals, the final element potentially has the same strength properties as the metal of the parts. This is in sharp contrast to non-fusion processes of joining (i.e. soldering, brazing etc.) in which the mechanical and physical properties of the base materials cannot be duplicated at the joint.

Welding: -3.3.4 for welding the angles together. In arc welding, the intense heat needed to melt metal is produced by an electric arc. The arc is formed between the actual work and an electrode (stick or wire) that is manually or mechanically guided along the joint. The electrode can either be a rod with the purpose of simply carrying the current between the tip and the work. Or, it may be a specially prepared rod or wire that not only conducts the current but also melts and supplies filler metal to the joint. Most welding in the manufacture of steel products uses the second type of electrode.

CONCLUSION:The proper guidance of project head and the sincere efforts of our group have led to the successfully accomplishment of our concerned projects. “AGRICULCHER FERTILIZER SYSTEM” was interesting to work on and was also gained in this project work... This knowledge of project will definitely be helpful in our future. So we must maintain that this final year project was an essential part of our engineering education enhancing our technical knowledge and practical skill. Our aim was to lift the maximum weight in minimum power consumption as to reduce the solar panel and motor cost. Hence we are provided our aim by design a suitable gear box to get maximum mechanical advantages .due to gear box the maximum torque required to lift the load is not coming directly on the motor shaft as we had seen it in the gear box design .so at the end shaft the speed is reduced which we are required & sufficient torque is increase to lift the load. Hence motor is revolving with min. load over its shaft with minimum solar capacity.
