Title: DEVELOPMENT OF AN IMPROVED SEED DRILL CHOKE INDICATOR

(Patent No. 232368 – A sensing device for use with a tractor)

Patent: Patent has been granted for the developed invention entitled “A sensing device for use with a tractor” in accordance with the provision of the patent Act 1970.

Inventors: A.K. Rai, K. Sivadasan and S.N. Murty (Directorate of Instrumentation, JNKVV, Jabalpur).

About the Device: Seed cum fertilizer drills are extensively used with tractor for sowing seeds and application of fertilizers in Agricultural fields. Modern seed cum fertilizer drills are famous for its proper seed rate, uniform distribution and correct placement of seeds in soil, while sowing nine channels seed cum fertilizer drills are generally manufactured in the country and are being used. Seed pass through the seed tubes of the seed cum fertilizer drills before dropping into furrows in fields. Due to excess moisture in soil or some other reason the seed tubes often get choked/blocked while sowing. To detect such choking a labourer is to be employed simply for monitoring the seeding operation. But due to human error often he fails to detect the choking immediately, resulting omission of seeding in certain rows in fields. This causes non uniform distribution and also reduces the yield. The above problem is more serious when sowing is done in night times. Keeping this in view, DST, New Delhi sponsored and Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur has developed the device to eliminate the above said problems by online monitoring of seeding activity and removal of choking channels whenever it occurs. The improved seed cum fertilizer drill choke indicator will be an attachment to the seed cum fertilizer drill available in the market. This innovation enhances the accuracy of seeding and fertilizer placement of the classical seed cum fertilizer drill. The implement consists of two parts viz. the Electronic part and the Mechanical part. The electronic part senses and indicates the choking in the seed channels and then sends audio and visual signals to the driver. After knowing that the choking has happened, driver can initiate the mechanical part to remove the choking.

Field trial of Improved Seed Drill Choke Indicator at JNKVV Farm

Main features of the improved system:

• During normal sowing condition, green LED of the status indication panel glows.
• While sowing, any one or more seed tubes of the seed drills, if get choked, corresponding red LED of that channel glows together with audio alarm.
• When the driver gets the audio-visual signals of choking he activates the choke removing system to remove the channel’s choke.
• After removal of choking, green LED will glow indicating the normal sowing condition.
• The status of the seed and fertilizer box is also monitored by the system. During sowing operation when seed and fertilizer box becomes empty, the system indicates this status by glows a yellow LED along with audio alarm.
• The system can be made operational using the tractor battery or a separate rechargeable 9 volt battery.
• Since the status indication panel of the system is small in size, it can be fitted near the seat of the tractor driver, so that he can take corrective measures according to the audio-visual indication.
• The modified sensing technology is used with new IR LED, which has high radiant intensity, directivity of light and low forward voltage. It encased in such a way that the sensing system is more reliable, flexible, rough use, easy to handle and easy for maintenances.
• For different crops (like wheat, paddy, gram, maize etc.) spacing of row to row are vary and adjustment of tynes spacing are required, so that choke removing fingers modified such a manner, its spacing are adjustable according to tynes spacing.

Title: MICROCONTROLLER BASED RICE POLISH MEASUREMENT SYSTEM

(Patent No.: 228921 – An apparatus for measurement of the polish percentage of rice)

Patent: Patent has been granted for the developed invention entitled “An apparatus for measurement of the polish percentage of rice” in accordance with the provision of the patent Act 1970.

Inventors: Bharati Dass, S.K. Jain and S.N. Murty (Directorate of Instrumentation, JNKVV, Jabalpur).

About the Device: The operation of removing bran layer from brown rice is known as polishing. This operation is very critical and the milling quality and quantity of rice depends on polishing process. The polishing operation in rice milling is important in terms of obtaining optimum polish percentage, avoiding breakage losses and consumption of energy. By quantitatively measuring the polish level one can enhance the quality of rice during polishing operation. The rice polish measurement system is microcontroller based and gives the reading directly in terms of polish percentage of rice samples for the calibrated varieties. The system consists of optical head unit, sample holder and single board computer. Rice samples approximately 180 gm are poured in the sample holder for taking measurement. The system is having the feature to calibrate for different varieties of rice.
