CULTIVATOR HAVING LIGHT EMITTING FUNCTION WITH EXCELLENT DISTINGUISHABILITY FOR FULL WIDTH USING PIEZOELECTRIC ENERGY HAVESTING

摘要

PURPOSE: A cultivator having a light emitting function capable of identifying the full width by using piezoelectric energy harvesting permanently generates electric energy using a piezoelectric sheet. CONSTITUTION: A loading part includes traction wheels and a loading box. A boarding part is arranged between a main body part and the loading part and includes a seat. A steering part (140) is arranged between the main body part and the boarding part and controls a driving direction. A light emitting part (150) emits light to the front side to identify the full width of the main body part. A piezoelectric part is loaded on the loading part and supplies electric energy to the light emitting part by converting vibration energy generated by the engine into the electric energy.
