The Design and Analysis of the System about Wind Sorting Fruit from Leaves Based on the Blueberry Picking Machine

摘要

As the plant areas of blueberries expand unceasingly,the realization of harvesting mechanization becomes more and more urgent.The fruit collection devices of the picking machine are designed with three-dimensional software Pro/E based on the blueberry picking machine.Meanwhile,wind sorting is used to realize the separation of fruit and leaves.In this paper,wind-sorting box is studied on the basis of the principle of wind sorting.The simulations of wind-sorting box inner are made with software FLUENT.A reliable basis is provided for the feasibility of wind sorting and a further analysis is made for the shape and the position of the inlet of wind-sorting box.And the structure of wind-sorting box is optimally designed.The improvement of the efficiency of wind sorting not only provides a theoretical basis for the separation of fruit-leaves of small berries,but also has an important meaning in agricultural machinery.
