Abstract
The seeder machine is of the unique techniques which is used for sowing seeds in standing stubble of crop residue. The clogging of boot in seeder is very common which results in missing of seed drop in lines. Many a times, a person stands behind the drill to observe it which is very pathetic and unsafe. A monitoring system has been developed to sense and indicate the clogging of boot in seed drills. The developed system has sensing unit, processing unit and audio-visual alarming unit as its integral components. The sensing unit contains ultrasonic sensor which senses the diametral length of the seed tube. An Arduino mega forms processing unit that performs logical operations based on the data received from sensing unit and sends signal to audio-visual alarming unit. The alert unit has 11 LED and a buzzer which gets activated according to the logic fed to the processing unit through code. The developed system was evaluated in lab on simulator and in field for detecting clogging during wheat and rice drilling. It was observed during laboratory evaluation that the clogging was detected and respective LED was ON when average 12.39 and 17.30 grams paddy and wheat was collected in a seed tube, respectively. In field evaluation, the average weight of seeds collected during this interval was 18.33 and 22.33 g for paddy and wheat, respectively. It is observed that there was an average time lag of 15 s in detecting clogging manually and the indication provided by the indication panel. Average distance covered by the seed drill before
detecting the seed clogging manually for paddy and wheat were 2.96 and 1.26 m at seed rate of 35kg/ha and 100 kg/ha, respectively which is 24.85 % higher when detected by the panel provided through LED glow and buzzer. Thus, the developed system was successful in sensing and indicating the clogging of seed boot during planting of paddy and wheat.
