The working principle of the invention comprises the following steps:

The prunes are placed on a feeding conveyor belt 177 one by one, the feeding conveyor belt 177 is started, the prunes are rolled from the feeding conveyor belt 177 to the slideway 3 and then to the prune holders 5, and each prune holder 5 is only rolled into one prune, meanwhile, the sorting conveyor belt 4 is started, the prune holders 5 and the prunes are driven to move below the first camera 21, the prunes can roll in the prune holders 5 under the blowing of the first air nozzle 25, the second air nozzle 26, the third air nozzle 27 and the fourth air nozzle 28, the prunes can be prevented from rolling outside from the prune holders 5 through the arrangement of the baffle 600, in the process of rolling the prunes, whether the surface of the prunes is damaged or not and whether the prune is Mei Da small can be detected through the first camera 21, meanwhile, the numbers on the prune holders 5 corresponding to each prune are recorded, when the prunes reach below the tester 1010 under the driving of the sorting conveyor belt 4, the sweetness of the prune is detected, and meanwhile, the number of the prune tray 5 corresponding to the detected prune is recorded through a second camera, when the prune is driven by a sorting conveyor belt 4 to move to a fruit drop box 166, the number of the prune tray 5 can be detected through a third camera, so that the information of the sweetness, whether the surface is damaged or not and the size detected before the prune with the number is obtained, each fruit drop box 166 is preset with a size range and a sweetness value for sorting the prunes with the same size range and sweetness value, when the prunes with different sizes and sweetness are just moved to the position above the fruit drop box 166 with the preset size and sweetness, the number of the prune tray 5 is determined through the third camera, and then under the action of an air tap 201, while the prune is blown off from the prune tray 5, the motor 300 is always started to drive the transmission shaft 301 and the rubber rod 302 to rotate clockwise (the clockwise direction is based on the clockwise direction in fig. 2), when the prune tray 5 passes under the rubber rod 302 (the prune in the 5 is broken prune and is not blown off by the air tap matched with the prior art), the rubber rod 302 is turned over when the rubber rod 302 touches the baffle 600, the rubber rod 302 is reset when the rubber rod 302 touches the prune, and the prune is pushed into the bad prune blanking box 303.

When the prune rolls from the feeding conveyor 177 to the slideway 3 and then rolls from the slideway 3 to the prune fruit support 5, after the infrared sensor 653 detects that one prune rolls from the lower part of the infrared sensor 643, the electric push rod 651 is started, the stop block 652 moves downwards to block the prune in the slideway 3, after a preset time, the electric push rod 651 is started to drive the stop block 652 to move upwards, so that the prune in the slideway 3 can drop onto the prune fruit support 5 one by one, and each prune fruit support 5 is ensured to drop only one prune.

Through the arrangement of the falling protection device, when the prunes are blown into the blanking plate 402, the prunes can reach the blanking hole 405 along the first inclined plane and the second inclined plane, then fall between the first turnover shell 506 and the second turnover shell 508 of the blanking assembly below from the blanking hole 405, then fall onto the first turnover shell 506 and the second turnover shell 508 of the next blanking assembly along the third inclined plane and the fourth inclined plane until falling onto the last blanking assembly, and then fall onto the bottom of the drop box 166, so that sorting and collecting of the prunes can be realized;

However, the prune rolling off from between the first overturning shell 506 and the second overturning shell 508 basically falls in the middle area, waste is caused by the space on two sides of the middle part, therefore, when the first observation camera 333 observes the prune in the middle area at the time of being fully collected, the electric rail 900 starts to drive the matching plate 901 to move upwards, when the matching plate 901 moves between the first gear 904 and the second gear 905 on the lowest blanking component, a plurality of first gears 902 on the matching plate 901 can be matched with the second gear 905, so that the second gear 507 rotates clockwise, the second overturning shell 508 is enabled to overturn downwards, a state as in fig. 14 is formed, at the moment, when the prune falls to one side of the middle part, when the first observation camera 333 observes the prune in one side area of the middle part to be fully collected, the electric rail 900 starts to drive the matching plate 901 again to move upwards, a plurality of second gears 903 can drive the first gears 904 to rotate, and the second gears 905 can be matched with the second gears 905, due to the fact that the first gears are separated from the second gears, the second gears are in a plurality of first gears, the second gears are in a reset state, the second gears can be matched with the second gears 905, the second gears can be used for being reset, the second gears can be used for being more conveniently and the second gears can be used, the second gears can be used for being used for the next time, the boxes can be emptied, the empty can be emptied by the time, and the empty boxes can be well can be emptied, and the empty can be well can be reduced, and the case can be well emptied.

When prune is collected in the middle of the fruit drop box 166, through the arrangement of the first moving plate 704, the second sloping plate 734, the first clamping groove 706, the first sloping plate 703, the first sloping plate 702, the second moving plate 804, the second clamping groove 806, the fourth sloping plate 834, the third sloping plate 803 and the second sloping plate 802, when prune drops onto the top surfaces of the first turnover shell 506 and the second turnover shell 508, the first sloping plate 702 and the second sloping plate 802 contacted with prune can move downwards under the gravity action of prune, the first sloping plate 702 can drive the first sloping plate 703 to move downwards, the first sloping plate 703 can drive the second sloping plate 734 to move, the second sloping plate 734 can drive the third sloping plate to move downwards, the third sloping plate 834 can drive the fourth sloping plate 834 to move, the fourth sloping plate 834 can drive the second moving plate 804 to enter the second clamping groove 806, so that the first turnover shell 506 and the second turnover shell 506 can be clamped by the gravity action of prune, the second turnover shell 506 can be blocked by the second turnover shell 506 and the second turnover shell 803, and the second turnover shell 506 can not drop the second turnover shell 506 can be guaranteed to be turned over by the first turnover shell 506 and the second turnover shell 803, and the second turnover shell 506 can be kept in a preset state;

When the first observation camera 333 observes that the prune collected in the drop box 166 is fast in height and contacts with the lowest blanking component, the working cylinder 501 is started to move the lowest blanking component into the mounting groove 500, and as the prune in the drop box 166 is higher and higher, other blanking components are sequentially returned into the mounting groove 500 from bottom to top, so that the influence on the placement of the prune in the drop box 166 is avoided.

When the second overturning shell 508 is overturned by the driving assembly, the second overturning shell 508 is limited by the cooperation of the first teeth 902 and the second gear 905, so that the impact force generated when the prune Mei Diaola is on the second overturning shell 508 is avoided to cause the second overturning shell 508 to overturne, and if the prune is in contact with the first overturning shell 506 when falling, the prune is also in contact with the first pressing plate 702 on the first overturning shell 506 firstly (the torsion force of the first torsion spring and the second torsion spring is larger than the tension force of the first tension spring and the second tension spring, so that the first tension spring and the second tension spring are pulled firstly under the gravity of the prune, and the first pressing plate and the second pressing plate are firstly moved downwards) to push the first pressing plate 702 to move downwards, so that the first moving plate 704 enters into the first clamping groove 706 to limit, and the first overturning shell 506 is not overturned due to the impact force of the prune, so that the prune assembly can be always kept in the state of fig. 14, and the prune is collected according to the stroke to the appointed side in the falling fruit box 166;

Similarly, when the first overturning housing 506 is overturned by the driving assembly, the first overturning housing 506 and the second overturning housing 508 can be kept in the state of fig. 13, and the prunes can not be overturned due to the impact caused by the falling of the prunes, so that the prunes can be collected on the designated other side of the drop box 166 according to the stroke, and the drop box can be placed in a preset sequence, so that the space of the drop box can be maximally utilized by arranging the first shifting plate 704, the second sloping plate 734, the first clamping groove 706, the first sloping plate 703, the first pressing plate 702, the second shifting plate 804, the second clamping groove 806, the fourth sloping plate 834, the third sloping plate 803 and the second pressing plate 802, and the first overturning housing 506 and the second overturning housing 508 in the middle part and at two sides.

The embodiments of the present invention are disclosed as preferred embodiments, but not limited thereto, and those skilled in the art will readily appreciate from the foregoing description that various extensions and modifications can be made without departing from the spirit of the present invention.
