ThesisItem Open Access ERGONOMIC ASSESSMENT OF MANUALLY OPERATED ROTARY MAIZE SHELLER.(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-10-11) GEDAM, KANCHAN VASANTRAO.; Thakare, Dr. S. K.Maize or corn (Zea mays L.) is a plant belonging to the family of grasses (Poaceae) which is most important cereal crop after wheat and rice produced throughout the country. From the carry out survey of existing practices of maize shelling, observed that the procedure of shelling maize is very difficult, and maize shelling efficiency is very low, these problems are solved by hand operated rotary maize sheller. Its work output depends on the machine as well as on the operator. So, for overcoming these problems develop user-friendly and safe mechanism of pedal operated for existing maize sheller with reduced drudgery and minimum seed damage. Therefore, the ergonomic study of maize shelling was felt very necessary. The present research work was carried out with the main objective so as to increase the human-machine system efficiency and also improve the operator’s health and able to operated with great efficiency, accuracy and safety. So, in view to focuses on energy considerations which arise from the physiological and psychophysical responses studied considering pedal length, seat height, backrest height with three different levels on modified pedal mechanism. The interpretation of the results of the study leads to the following major conclusions. Physiological and psychophysical responses were affected by pedal mechanism and minimum values were observed with pedal length 180 mm, sitting height 710 mm and backrest height 400 mm, respectively. The lowest working heart rate, increase in heart rate and oxygen consumption rate were observed to be 101.67 beats min -1, 27.5 beats min -1 and 0.34 lit min-1, respectively whereas body-part discomfort score, overall discomfort score and percentage of maximum oxygen consumption rate were found to be 7, 2.88 and 19.62 %, respectively. However cardiac cost of operation and energy expenditure rate was found to be 9.5 beats kg-1 and 8.81kJ min-1, respectively and highest output capacity i.e. 220 kg h-1 was obtained at same combination. So, working heart rate in existing maize sheller in “very heavy” and in modified maize sheller categorized in “moderately heavy”. It may be concluded that the pedal mechanism can be successfully used as an interface between the human worker and a hand rotary type machine for getting more output from the machine with less effort and fatigue as compare to existing maize sheller.ThesisItem Open Access DEVELOPMENT OF SMALL TRACTOR OPEATED BROAD BED FURROW MAKER.(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-09-24) TELANG, KUNAL HARISHYAM.; Khambalkar, Dr. V.

SMITA NATWARLAL.; Thakare, Dr. S. H.The modern method of sowing is planting with the help of planter. Planter is a device that deposits seeds at equal distance in rows at specified rates and covers them with soil, so it is the time to have the machine which can perform function of planter and raised bed former in one combine unit. Considering the lack of appropriate planting, cultivation and harvesting machinery for mechanized garlic production, it is still grown in relatively small fields using traditional method. It requires about 60-65 man days to sow one hectare which costs around Rs. 16250 per ha. Therefore, in this study an innovatively designed tractor operated, ground wheel driven, ten row raised bed, crop precision planter capable of planting ten rows of garlic cloves at a spacing of 10×15 cm was designed, fabricated and tested at Department of Farm Power and Machinery, College of Agricultural Engineering and Technology, Dr. PDKV, Akola. During the course of experiment, efforts were made to study biophysical characteristics of garlic cloves in terms of size, unit mass, bulk density and angle of repose. Laboratory test for germination percentage was also carried out. For finalization of metering mechanism three different types of metering mechanisms viz. cup type, spoon type and inclined plate of metering mechanism were tested on sticky belt set up and considering the performance of each metering mechanism with respect to average seed spacing, miss index, multiple index, and damage percentage for the forward speed of 1.8, 2.65 and 3.10 km/h. From these experiments, spoon type mechanism was found to have better performance than cup type and inclined plate mechanism. Hence spoon type mechanism was selected and its size was optimized by considering three different sizes of spoon for agri-found G-41 variety. The selected spoon size based on its performance was used in metering mechanism of prototype and was tested for its performance in the field for theoretical field capacity, effective field capacity, field capacity, field efficiency, miss index, multiple index, germination percentage etc for three different speeds of 1.8, 2.6 and 3.1 km/h and for two bed heights of 20 and 30 cm. The data obtained during the course of experiment were analyzed and based on results it is concluded that the tractor mounted, 10 row, raised bed precision planter was found suitable for planting graded garlic cloves on a raised bed of 2.1 m wide with the forward speed of 1.8 to 2.65 km/h for minimum multiple index, miss index, seed damage, fuel consumption, draft and power requirement. Ten row raised bed garlic planter gives best results for 1.8 km/h speed and 20 cm bed height combination. The highest germination of 89 percent with lowest seed rate of 615 kg/ha was observed for the same combination. Lowest miss index of 10.51 per cent and multiple index of 3.14 per cent indicated better performance of the machine. More specifically with a theoretical spacing of 10 cm in the study only 3.14 percent of clove spacing was less than or equals to 5 cm. The level of multiple index is considered to be low and acceptable. This combination demands lowest power of 3.45 hp and gives highest field efficiency of 77 per cent. The maximum germination percentage of 89 percent was recorded at forward speed of 1.8 km/h and 20 cm furrow depth suited to best soil moisture conservation practice. The minimum germination percentage of 65 percent was recorded at forward speed of 3.1 km/h and 30 cm furrow depth. It was observed that there is saving in cost of operation by 78.12 per cent over traditional practices and saving in seed by 20 to 30 per cent with increase in yield by 25 to 30 per cent over traditional method.ThesisItem Open Access DEVELOPMENT AND PERFORMANCE EVALUATION OF SMALL TRACTOR OPERATED FOLDING TYPE STUBBLE COLLECTOR.(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2018-09-23) GUJAR, SEVAK SANTARAM; THAKARE, S.
