Background

The furrow opener is the main working component of the seeding machine. A seed ditch with a certain depth can be formed on a seedbed according to the agricultural technical requirements, seeds (fertilizers) are guided to fall, and wet soil is covered. The working quality of the furrow opener directly influences the sowing quality.

The seedbed is the environment for seed germination, rooting and emergence, so that the humidity of soil and the quality of soil have great influence on the germination of seeds. The firmness of the soil can affect the germination and rooting of the seeds by absorbing soil moisture. The soil is too soft and loose, which affects the moisture transportation of the seeds and the germination condition of the seeds. But too hard to help the growth of the root system of the seedling. In no-tillage land, the firmness of the soil is greatly increased, so that the development of seeds is facilitated, a furrow opener is required to loosen the soil, and the soil below and on two sides of the seeds is ensured to be loose. Moreover, from some documents, people rarely research the viscosity reduction and soil removal of the furrow opener to reduce the furrow opening resistance. The phenomena of the quality reduction of ditching, the increase of working resistance and the like can occur after the clay is arranged in the ditcher, the seeding quality is greatly influenced, and the crop yield is finally reduced. Therefore, viscosity and drag reduction is a problem to be solved in the design of the furrow opener.
