The starting position of the charging plate 3 is located below the discharge port of the feeding cylinder 1, which can be understood as a charging area, an open recycling bin 5 is placed below the charging plate 3 in the charging area, the charging plate 3 moves forward under the driving of the driving belt 2 to enter a sorting area, light shielding plates 6 are respectively arranged at two outer sides of the driving belt 2 in the sorting area, a baffle 7 is fixedly connected between the light shielding plates 6, the baffle 7 is located at the inlet of the sorting area, and when the charging plate 3 passes through the baffle 7, the baffle 7 abuts against the plums completely located at the top of the groove 31, so that the extra plums are stirred into the recycling bin 5.
The reason for the baffle is that when the plumes fall from the supply cylinder 1, they drop directly onto the loading plate 3, some of the loading plate recesses 31 will have more than two plumes stuck at their open ends, some recesses 31 will have only one plum, and the recesses 31 of the present device can actually only accommodate one plum, which will have to be significantly higher than the loading plate 31 if a plurality of plumes are stuck at the recess opening, and the loading plate 31 will continue to move forward, and when passing the baffle 7, the extra plumes will abut against the baffle 7 and will be cleaned. The arrangement is to ensure that at most one plum is placed in each groove 31 area so as not to interfere the accuracy of subsequent detection and identification.
Preferably, the groove 31 of the present embodiment is a cylindrical structure with a hemispherical bottom wall, the top wall of the groove 31 is flush with the charging plate 3, the depth of the groove 31 is greater than the diameter of the bottom wall, and the baffle 7 is arranged at a position 10mm above the charging plate 3.

When the color of plums in the charging plate 3 is detected to meet the specified requirements, the controller controls the valve body 9 at the bottom of the groove 31 for containing the plums to be opened, the plums drop to the collecting box 8 below along the trend, and therefore the plums are stored in stages according to different colors, namely according to different maturity.
Wherein the computing and analyzing system stores the reference image information of plums at different maturity, and compares the digitized signals with the reference image information to make analysis.
It will be appreciated that the image processing system stores information about the position distribution of the loading plate recess 31, which facilitates accurate control of the valve body 9 in different positions.
In order to achieve the economic benefits of plums more greatly, it is necessary to grade the plums as finely as possible, and preferably, the present embodiment is provided with four sorting zones, wherein the first sorting zone is used for collecting plums with the maturity of more than 90%, the second sorting zone is used for collecting plums with the maturity of 60-90%, the third sorting zone is used for collecting plums with the maturity of 30-60%, and the fourth sorting zone is used for collecting plums with the maturity of 0-30%.
Preferably, above each sorting zone, a set of vision sensor and colour sensor corresponding thereto is provided to capture the appearance image of the plums, said vision sensor being used to detect and identify the loading of each recess 31, helping to locate the position of the plums; the color sensor compares the captured appearance image with its own stored reference image to make an analysis. When the transmission belt 2 transmits the loading plate 3 to the first sorting area, the sensors of the first sorting area perform detection and identification, and when the color of the plum is detected to be close to a reference image with the maturity of more than 90%, the vision sensor and the color sensor respectively send signals to the controller, and the controller then controls the valve body 9 of the groove 31 where the plum is located to be opened, and the plum falls to the collecting box 8 below along the trend; similarly, when the loading plate 3 moves forward to the second sorting area, the sensor in the second sorting area detects and compares the detected result with the standard image with the maturity of 60-90% to obtain the plums with the maturity; and so on until all the plums are sorted into different collection bins 8. After all the plumes have been sorted, the conveyor transports the loading plate 3 back to the starting position to be ready for the next loading.
