Technical field

The invention relates to the field of agricultural machinery, in particular to an electric transplanter and an application thereof.

Background technique

The traditional plant transplanter uses the internal combustion engine as the power source for the agricultural machinery. When the agricultural machinery operator operates the traditional plant transplanter for plant transplant, the internal combustion engine that is powered by burning diesel, gasoline, etc. will generate harmful gases, especially the agricultural machinery in the bump. When it is used in an environment where the soil is not flat or the soil is relatively soft, the internal combustion engine needs to provide a large power to increase the torque of the agricultural machine and ensure the normal operation of the agricultural machine. This will cause the combustion of the internal combustion engine to be insufficient, so that the internal combustion engine emissions are increased. The composition and concentration of harmful substances in the gas, which will bring greater impact and harm to the environment and the operators of the agricultural machinery.
