Evaluation parameters afeccting the performance of vibrating vertical tillage equipment - First stage

Paper ID- AMA-05-08-2021-10508

The purpose of this study was to evaluate alternatives to reduce energy consumption applied to soil clearing. To do this, we developed an experimental device and evaluated the operation of the vibration-induced parameters. System integrated components for on-site evaluation: Frame tool carrier with introduction of three-point hitch and depth control mechanism system: Introduction of three sensors to measure tillage force, torque and frequency of subsoiler vibration Met. The oscillating impact force was applied through the rod and crank mechanism in the subsoiler whose motion was provided by the hydraulic motor. The device evaluation was complemented by a signal regulator and data collection system that allowed the registration of variables of interest such as system traction, penetration, applied torque and vibration velocity. The sensor calibration results showed a system correlation of 95% or more. In the field system verification at different speeds, amplitudes and depths of tillage, the traction force was reduced by up to 50% by using vibration-induced tillage compared to the non-vibration tillage state. This study showed a significant 33% increase in traction and torque magnitude when the working depth increased from 0.30 to 0.40 m. The traction force increased by 21% when the vibration amplitude decreased from 0.0707 to 0.060 m. No significant difference was found when the tractor velocity increased from 1.5 to 2.5 kmh -1. For future research, the device developed makes it possible to determine how tilling amplitude and working depth and vibration frequency affect traction in tilling work.

Development of a front mounted cultivator for power tiller

Paper ID- AMA-05-08-2021-10507

We designed and developed a front-mounted hydraulically driven cultivator in consideration of the negative traction force developed by the rotary cultivator and the traction capacity of the power cultivator. A suitable linkage system was designed and a cultivator was installed in front of the power cultivator. Field performance of power cultivators was measured with both front-mounted cultivators and rotary cultivators and with rotary cultivators only. These results show that the power cultivator has a 50% improvement in tillage performance index and soil when operated with a combination of front-mounted cultivator and rotary cultivator, compared to when operated with a rotary cultivator alone. Size and fuel consumption were shown to decrease significantly by 50% and 13%, respectively.

Design, development and evaluation of manually-operated check row planter for dry sowing of rice

Paper ID- AMA-05-08-2021-10506

A manually operated regular row seeder for dry sowing of rice capable of planting two rows of rice at intervals of 25 cm x 25 cm was designed, manufactured and tested. The effective field capacity of the seeder was found to be 0.023 ha / h at a field efficiency of 47.38%, and the seeding rate was 10.1 kg / ha. Miss index, multiple index, and seed damage were 6.6%, 13.3%, and 2.1%, respectively. A comparative study was conducted to evaluate the performance of transplanting, spot seeding, and regular row seeding machines in the System of Rice Intensification (SRI). To sow on 1 hectare of land, the sowing machine required Rs.853 / ha (1US $ = 72Rs), which was less than manual transplanting and spot sowing in SRI. The developed seeder saved 66.7% and 72.4% cost compared to manual transplantation and spot seeding.

Development a table top centrifugal dehuller for small millets

Paper ID- AMA-05-08-2021-10505

Millets with great health benefits, small nutritious grains are growing worldwide for food and feed. Due to the typical structure, hardness and small size of the shell grains, millet threshing remains a constraint. This study deals with the performance evaluation of the developed low-cost tabletop centrifugal threshing machine. Threshing experiments were performed on five millets at three moisture contents (11.1, 13.6 and 16.2% db) and three peeling rates (6000, 5,500, and 6000 rpm), namely foxtail millet, little millet, millet, kodomillet and barnyardgrass. The water content of the grains had a significant effect on threshing performance compared to the threshing rate, which had a lesser or negligible effect on time. The highest average threshing efficiencies obtained for millet, little millet, and millet were 92.7, 91, and 93.5%, respectively, at a grain water content of 13.6% (db) and a threshing rate of 5,500 rpm. The highest average threshing efficiencies for barnyardgrass and barnyardgrass were 80.9% and 74.4% at 11.1% (db) water content and threshing rate of 6000 rpm, respectively. For the same experimental combination, the rate of destruction was less than 5% for millet, little millet, and millet, but 5.7 and 9.2% for codomillet and barnyardgrass, respectively. The average threshing shell grain ratios to foxtail millet, little millet, millet, codomillet and barnyardgrass were 2.4,5.7,2.3,14.2 and 18.1%. The approximate cost of converting 1 kg of millet to rice is INR 0.97 ($ 0.01).

Development and testing of a coconut dehusking machine

Paper ID- AMA-05-08-2021-10504

Nigeria is known for its annual production of over 265,000 tonnes / year of palm. Palm dehulling has been done manually using machete. Due to the difficulties involved in manual palm dehulling, it is necessary to mechanize the work by developing an indigenous palm shell peeling machine. This machine consists of spikes, chain drive, gears, electric motors, bearings, shafts, reduction gears and sprockets. The machines performed best with local varieties of palm with an average water content of 5.08% (db), giving average mechanical capacity and percentage throughput of 175 coconuts / h and 84%, respectively.
