The size and shape of the fruits selected by the orange classifier are basically the same, which is conducive to packaging, storage and processing. Therefore, it is widely used in fruit classifiers. Through the evaluation of the shape, size, color, fruit surface defects and damage of all appearance quality indicators of the fruit It can analyze the characteristic information of each fruit, judge the grade of each fruit and the position information of the fruit, and then realize the intelligent real-time detection and classification of it, and then the fruit is graded and packaged. The application of fruit classifiers in actual production will help improve labor productivity and fruit commodity value, and increase agricultural benefits and farmers' income, with huge economic and social benefits.
The working principle of the orange grading machine is: after pouring the picked fruit into the fruit washing tank, start the control device of the machine, so that it can be cleaned, transported, cleaned, transported, converted from multiple rows to a single column, grading recognition and offline sorting operations. , can fully realize automatic classification. Therefore, the secondary machine includes the following parts: fruit washing tank, washing conveyor, fruit washing machine, waxing machine, fruit wax drying machine, transportation device, multi-row fruit production line into a single line mechanism, fruit grade identification device, offline fruit classification structure.
In order to reduce fruit collision and improve fruit yield, some classifiers use buoyancy method, vibration method and grid method for classification. Fruit selection screens with different mesh sizes are installed in the upper part of the fruit selection tank, and the vibrating part is set in the washing tank. During sorting, the fruit is first fed into the tank, and when the vibrating part vibrates, the fruit in the tank gains kinetic energy and moves. When the fruit is moved to the grid corresponding to its size, the fruit pours out of the water through the grid, stays in the corresponding grid slot, and then receives, that is, the fruit grading process is completed. The advantage of this method is that the collision between the fruits is avoided, and the fruits can be cleaned at the same time of sorting.
