The design of rice direct seeding machine

Abstract

In order to change the existing status of big turning radius of the large direct seeding machines with diesel and gasoline as fuel and improve the low efficiency and time-consuming condition of the machine driven by human or animal, an electric rice planter was designed. The mechanical parts and circuit design had been finished. The rear wheel shaft, seeding wheel, seeding frame and other key parts had been designed. The charging circuit of the maintenance-free storage battery and the power supply circuit of the DC motor had been given. The main technical parameters of the rice planter as follows, L * B *H: 1700 * 1200 *1200 (mm), row distance* planting distance*width = 250 * 200 *1000 (mm). The rice planter driven by DC motor and maintenance-free battery has a compact structure, a small turning radius, and it can be used in hills and mountainous regions.
