Electric Cultivator Design and its Impact of the Operator
Small type gasoline engine has the advantage of lightweight and low energy, but its emissions of carbon dioxide will lead to global greenhouse gas growing. This study aims to test the performance of the cultivator between different soil and tools. Comparative test electric and gasoline engine type cultivator contains the following items: energy consumption, carbon dioxide emissions in the job and the operator heart rate change. The results show that the width of 60 cm and depth of 3 cm operating conditions weeding, electric cultivators and gasoline engine cultivator average turn time was 2.9 seconds and 3.3 seconds, with an average forward speed were 0.535 and 0.515 m/s. Comparison of the time and forward speed cornering, the electric cultivator superior gasoline engine cultivator, and can successfully achieve high torque output characteristics weeding needed. Energy consumption and carbon emissions test data show that the loam fields, the average power consumption cost of NT $ 21.2/ha; carbon dioxide emissions by an average of 26 kg/ha. This result shows that energy consumption in the consideration of the performance of carbon dioxide emissions, electric cultivators have lower costs. The test results are displayed in the field; the electric cultivator operator heart rate is lower than the gasoline engine cultivator and has significant difference statistically. Therefore, in the field of long-term operating conditions, the electric cultivator helps reduce physical exertion and operator fatigue.
