ABSTRACT • 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 two wheels,a bevel gear has been attached to the axle of these wheels • A impeller disc has been attached to the bevel pinion. • A hopper whichis used to store the fertilizer is placed above the impeller disc And The fertilizer tends to fall over the Impeller disc • It leads to equal distribution of fertilizer to crop • The flow can be controlled using a flow control mechanism

INTRODUCTION • In the recent days it has been found that farmers are unable to gain more crop production by use of conventional agricultural methods. • So there is big need for the development of engineering system for compensating these drawbacks. • The major problem faced by the farmers is shortage of labor’s and also the time required for Fertilization is more. • So in order to have solution to it, it was proposed to manufacture a Fertilizer Spreader machine.

OBJECTIVE The Fertilizer Spreader machine should satisfy the following objectives: • To Maximize the land cover. • To reduce the time consumption of fertilization process • To be driven manually • To spread the fertilizer uniformly

COMPONENTS • Wheels • Bevel gears • Impeller disc • Hopper • Handle and stand

MATERIAL PROPERTIES 1.WHEELS: Material – Plastic

2.BEVEL GEAR: Material - wood No of teeth in bevel gear – 20 teeth No of teeth in bevel pinion – 10 teeth

3.HOPPER: It is used to store fertilizer Material – Plasti

4.IMPELLER DISC: It is used to spread the fertilizer Material – Steel Dimensions Diameter of Impeller = 22.86 cm Length of Impeller plates = 12.7 cm Height of Impeller plates = 2.54 cm

5.HANDLE AND STAND It is used to the instrument Material – Steel

METHODOLOGY • It is to provide a simple and inexpensive fertilizer spreader in a form of a two wheeled walk behind device. • This device is pushed manually by the rotation of wheels gets converted in to vertical rotation of spreading disc by the set of bevel gear. • The spreading device normally has a bladed. • The centrifugal spreader comprising disc which is rotated aboutvertical axes and onto which the product to be spread on theground is dropped in a suitable manner. • This is a type of spreader which can be operated manually for spreading granular materials in farms.

DESIGN OF FERTILIZER SPREADER

1-Hopper 2-Stand 3-Wheel 1 4-Bevel Gear 5-Axle

6- Bevel Pinion 7-Wheel 2 8-Connecting Rod 9-Impeller Disc 10-Handle

DESIGN CALCULATION Normal walking speed of man = 1.4 m/s = 23.33sec Distance of area = 40.46856 m2 Formula: Distance = speed x time Time = distance / speed Spreading distance d = vt + ½ at2 Acceleration a = velocity / time taken

Solution: Time = 40.46856 / 23.33 = 1.73 sec

To Find Spreading Distance Spreading distance d = vt + ½ at2 Acceleration a = velocity / time taken a = 1.4/ 1.73 = 0.8092 d = 1.4 x 1.73 + ½ x 0.8092 x (1.73)2 d = 2.422+1.2109 d = 3.632sq.feet Spreading distance d = 3.632sq.feet

ADVANTAGES • Time savings. • Less fatigue to labor. • High speed Fertilization. • Applicable for small and medium farms. • No electric power required. • Easy to operate, as no skilled operator required. • Easy to assemble. • It is pollution free. • Maintenance cost is low.

DISADVANTAGES • Machine requires more effort in hard soil. • Operating force varies from person to person. • Manually operated, so it is difficult to run continuously.

COST ESTIMATION

CONCLUSION • By taking trials on the field of our machine and gathering all information of other possible methods we have got following results. • The wastage of excessive use of fertilizer has been reduced • It covers maximum land. • The main objective of our project was to fulfill the need of farmers suffering from the problems of increasing cost of Fertilization, labor cost and availability as it is operated by single person. • 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%

PROJECT PHOTOGRAPHS

STEPS NEED TO BE TAKEN TO IMPROVE • Hopper should be funnel shaped so no fertilizer remains in it. • Bevel gear must be made into accurate dimensions. • Flow control should be regulated
