Background Art

The weeder is one of the main weeding equipment in agricultural work. It uses the high-speed rotation of the engine to drive the blade to weed and break the roots, saving the working time of weeding workers and reducing a lot of human resources. However, due to the strong vitality of grass roots and grass seeds, even if the root system is partially broken, there are still weeds with strong vitality that can revive. The current means to solve this problem are usually to spray pesticides or use flames to burn the soil. Spraying pesticides can easily cause soil pollution and affect the environment. Using flames to burn the soil can easily cause the fire to spread. It is easy to cause fire when used in flammable environments such as mountains, and it poses a great threat to the personal safety of operators.

Weeding is very important in agricultural production. Grass growing in farmland greatly affects the growth of crops, so a weeder is needed for weeding. Different weeds require a weeder with blades of different spacings. Because the volumes of different weeds are different, the blade spacing of the weeder needs to be adjusted. Therefore, a weeder is proposed.
