CAPACITOR BANK BASED AGRICULTURE SPRAYER
Field of Invention
The invention relates to the agriculture machine for the purpose of the spraying pesticides.
Background of the invention
Conventional systems are operating with petrol engine with lack of information about the current parameters.
These are the concern for the inventors to find an effective system that will factor the above said deficiencies of the present system.
Objective of the Invention
The objective of the invention is to work with electrical motor through capacitor bank for clean, eco friendly and information about the spraying.
Statement of Invention
Capacitor bank based agriculture sprayer consist of DC motor, motor speed control circuit, capacitors, flow meter, liquid level indicator, motor RPM indicator, automatic filling system, solar power pack unit and PWM controlled LED .
Once the capacitor is charged using solar power pack unit it is ready to drive the DC motor. The liquid is filled using an automatic system. It consists of pumping motor and delivery hose which is fit with the liquid reservoir of the

sprayer. As soon as the pumping motor is ON, liquid flow from the collection point to the sprayer reservoir until the reservoir is full and the pumping motor goes OFF. Now the hose is detached from the reservoir. The filling information is indicated by the PWM controlled LED. The sprayer DC motor is switched ON and speed control knob is varied to suit our required RPM. The air blower attached with the shaft of the DC motor rotates and its velocity is calculated and indicated using PWM controlled LED. Then the flow cock is turned ON and it is spraying on the field. All the sensors, switches, driving unit, indicating units are connected with the ATMEGA328 micro controller. As soon as the reservoir becomes empty it gives warning signal using buzzer and controller switch OFF the motor then ready for refilling.

DETAILED DESCRIPTION OF THE INVENTION.
Capacitor bank based agriculture sprayer consist of DC motor, motor speed control circuit, capacitors, flow meter, liquid level indicator, motor RPM indicator, automatic filing system, solar power pack unit and PWM controlled LED.
Once the capacitor is charged using solar power pack unit it is ready to drive the DC motor. The liquid is filled using an automatic system. It consists of pumping motor and delivery hose which is fit with the liquid reservoir of the sprayer. As soon as the pumping motor is ON, liquid flow from the collection point to the sprayer reservoir until the reservoir is full and the pumping motor

goes OFF. Now the hose is detached from the reservoir. The filling information is indicated by the PWM controlled LED. The sprayer DC motor is switched ON and speed control knob is varied to suit our required RPM. The air blower attached with the shaft of the DC motor rotates and its velocity is calculated and indicated using PWM controlled LED. Then the flow cock is turned ON and it is spraying on the field. All the sensors, switches, driving unit, indicating units are connected with the ATMEGA328 micro controller. As soon as the reservoir becomes empty it gives warning signal using buzzer and controller switch OFF the motor then ready for refilling.
Capacitors c9, Cl0,cll,cl2,cl3,cl4,cl5,cl6,cl7 and cl8 are connected in
series to store 24 v DC. This capacitor bank is connected in parallel with cl9
capacitor and BAT1 battery. This setup is connected to the H - bridge motor
driver circuit. The motor driver circuit consists of two IR2112 Half bridge driver
chips(U2,U3),four IRF540N MOSFETs (Q2,Q3,Q4,Q5), diodes
(D5,D6,SD7,D8,D9,D10), Resistors (R6,R7,R8,R9,R10,R11,R12,R13), capacitors (C1,C2,C3,C4,C5,C6,C7,C8) and fuse.
Pumping unit consist of pump ON button, level switch, pumping motor, relay RL1, Transistor Q6, resistors (R14,R15,R16,R17). Buzzer unit consist of BUZ 1, transistor Ql and resistor R4. Sensors used in the system are airflow sensor RV3, liquid sensor RV4, reservoir level sensor RV2, tachogenerator and speed control potentiometer RBI. Indicator unit consist of PWM controlled LEDs (D1,D2,D3,D4) and resistors( R1,R2,R3,R5). ON/OFF switch SI.
