Automatic Seed Sowing Machine ppt

The aim of this project is to design and develop a solar operated seed sowing machine. The seed sewing machine is a key component of agricultural field. The various technique used in India for seed sowing and fertilizer placement are manual, ox and tractor operator. But we wanted lowest cost but efficient also, so we made this remotely operated seed sawing machine

2. ABSTRACT In the farming process, often used conventional seeding operation takes more time and more labour. To meet the future food demands, the farmers have to implement the new techniques which will not affect the soil texture but will increase the overall crop production . Sowing machine should be suitable to all farms, all types of corps, robust construction, also it should be reliable, this is basic requirement of sowing machine. We made it from raw materials thus it was so cheap and very usable for small scale farmers . For effective handling of the machine by any farmer or by any untrained worker, we simplified its design. Also, its adjusting and maintenance method also simplified.

3. INTRODUCTION Automation saves a lot of tedious manual work and speeds up the production processes. Seed has been an important agricultural commodity since the first crop plant was domesticated by pre-historic man. In this model seed sowing process is automated to reduce the human effort and increase the yield. The plantation of seeds is automatically done by using DC motor . The seed block can be detected and solved using water pressure . As agriculture is extensively supported by technical means like seeding, mowing or harvesting machines, it is widely considered to be a field with a high potential for robotic application as it is a small step from these semi automatically operated machines to fully autonomous robots in both greenhouse and open field applications.

4. OBJECTIVE 1. The main objective of this project is to design and fabricate smart seed sowing machine. 2. As we all know the main requirement in the industry or any firm is man power . 3 . Make this smart machine economical and user friendly for Indian farmers to operate. 4 . To implement functionality of adding the number of seeds to be sowed using keypad. 5. To make this vehicle Electrically powered so that the farmer need not worry about self efforts.

5. METHODOLOGY A battery operated D.C. motor is used transmits the rotary motion to the shaft with the help of chain drive, and there is another connection of sprocket and chain to the rotary motion. Seed Sowing process.. Structural frame Battery powered wheels Seed storage tank. Seed sowing disc Seed bucket. Seed chamber.

6. VARIOUS PARTS OF SOWING MECHANISM BATTERY CHARGER : UPG D1724 SEALED LEAD ACID BATTERY CHARGER (6V/12V SWITCHABLE SINGLE-STAGE WITH ALLIGATOR CLIPS). 500 MAH

7. BATTERY :

8. Chain Drive : In our project there are two chain drives one which used to control the flow rate of seeds and another which is used to transmit the power from motor to peg wheel.

9. Gears : Gears are used to transmit the power from one shaft to another mechanism. In our machine we are using 4-5 gears which having bucket teeth. It has no. of teeth on different steps which is used for control the speed of disc.

10. Hopper : Hopper is made by mild C. R. Sheet which contains Seed .

11. Wheel: The rim of the wheel is made from a plastic . & it has very low cost though. Seed storage tank : Storage device is one of the important devices of the system. Shaft: It is made of C. I. on which disc and four gear sprockets is mounted. It is used to transfer the power from ground wheel to each disc.

12. Dc Motor: Stepper DC motor A dc motor is a device that converts direct current (electrical energy) into mechanical energy. Two dc motors are used for driving the wheels connected to the robot. L293d is a dc motor driver used for driving dc motors.

14. Sr. No. Components Specifications 1. C. R. Sheet Length 550mm 2. Height of the sheet 4mm (3 Layers ) 3. Width of the sheet 350mm 4. Wheels 4 – (140mm Each ) 5. Power Transmission Ground Wheel to shaft 6. Storage Tank Height 300mm 7. Width of the tank 150mm 8. Length 350mm 9. Motor 200rpm 10. Battery Capacity 12 Volts 11. Operating Speed 1.o to 2.0 (km/hr.) 12. Labour Requirement 4 to 5 13. Machine Weight 15.9 kg Specification of Components

15. Calculations Power = Force * Velocity = 200 * 0.08 * 2 * 3.14 * 11/60 = 18.42 watt Torque = p/ω = 18.42 * 2 * 3.14 * 11/60 = 21.20 N-m Used 20 teeth’s gear for transmission. Energy Storage Capacity of Battery = 12v Used Dc Motor for Forward Reverse

16. Advantages: 1. These machines are adequately designed with auto seed feeding system planting channel for optimal growing conditions. 2. Adjustable seeding rate. 3. Seed monitor and hectare counter. 4. Spring loaded plunger for seed dropping. 5. No extra manpower required. 6. It is compact in size.

17. Dis-advantages: 1. Needs prepared soil at the correct temperature. 2. Small seeds often get sowed too thickly and need to be thinned. 3. No control over the depth of seed placement.

18. Application: Gardening. Farming The design of furrow openers of seed drills varies to suit the soil conditions of particular region .

19. Why This Project ? This project is more suitable for a common man as it have much more advantages i.e . no fuel cost, no pollution, and no fuel residue, less wear and tear. physical exercise. Mass productions can cut the cost of the device.
