Improved working tool for loosening the soil in the rows of berry crops
Technologies for the care of berry plantations involve the use of manual labor for tillage between the bushes of plants. The lack of mechanized soil care between plant bushes stops many farmers from planting new plantations. The purpose of the research is to improve the layout of the working tool for loosening the soil in the rows of berry crops. An experimental setup with a device for inter-waste tillage was developed and tested at the institute. It was found that the asymmetric working body with a radius of rotation of the teeth loosening more than 0,5 m practically does not work. The minimum and economically feasible radius of rotation of the loosening teeth located at the same distance from each other on the arc of the circle of the asymmetric working tool is justified. The dependence of the loop width of the elongated cycloid and the length of the soil tillage area on the distance between the plant bushes in the rows of berry crops to determine the required number of loosening teeth is presented. The scheme of the improved working tool in the form of a rotating asymmetric circular sector with loosening teeth located on the arc of the circular sector is presented. An expression defining the angular measure of the circular sector is obtained.
