[0002] The function of the furrow opener is to open a furrow and guide the seeds or fertilizers into the furrow during the sowing operation, and to cover the soil with seeds or fertilizers. In the process of crop planting, furrowing is an important operation link, and the quality of furrowing operation has an extremely important impact on the yield of crops. When planting crops, different furrow openers should be selected according to the sowing requirements of the crops, regional climate and soil conditions. Furrow openers can be divided into two categories according to the different angles of entry into the soil: acute-angle furrow openers and obtuse-angle furrow openers. Acute-angle furrow openers have better soil entry ability and poor passing ability; obtuse-angle furrow openers have poor soil entry ability and better passing ability.
