[0021] 5. The fruit sorting device and system can separate the fruits according to their sizes by setting two adjusting rods, so that it is convenient to grade the fruits according to their sizes. The distance between the two adjusting rods can be adjusted by setting a bidirectional threaded rod, a knob, a moving block, a slide groove and a slider, so that it is convenient to adjust according to the sizes of different fruits, thereby improving the practicality of the device.

[0022] 6. The fruit sorting device and system can generate airflow by arranging an air pump, an exhaust frame and a mesh plate to reduce the falling force generated by the falling fruit, thereby avoiding damage caused by bumps during the falling process of the fruit, making the fruit sorting more stable and reducing the bad fruit rate.

[0042] A fruit sorting system comprises a feeding mechanism 2, a diverter frame 3 and a sorting device, wherein the feeding mechanism 2 is arranged on the top of an operating platform 1, and the feeding mechanism 2 comprises a first roller conveyor belt 201, a first motor 202, a first pulley 203, and a slag discharge plate 204, wherein the first roller conveyor belt 201 is fixedly mounted on the top of the operating platform 1, the first motor 202 is fixedly mounted on the outer wall of the first roller conveyor belt 201 and is fixedly connected to the rotating shaft of the first roller conveyor belt 201, the driving wheel of the first pulley 203 is fixedly connected to the rotating shaft of the first roller conveyor belt 201, and the driven wheel of the first pulley 203 is fixedly connected to the rotating shaft of the second roller conveyor belt 4, the slag discharge plate 204 is fixedly connected to the inner wall of the first roller conveyor belt 201, and the two ends of the diverter frame 3 are respectively fixedly connected to the outer wall of the first roller conveyor belt 201 and the outer wall of the second roller conveyor belt 4;

[0043] Working principle: spherical fruits are placed on the first roller conveyor belt 201, and the first motor 202 is started to drive the first roller conveyor belt 201 to convey the fruits. Impurities such as leaves and branches in the fruits will fall onto the slag discharge plate 204 through the gap between the rollers on the first roller conveyor belt 201, and then slide down the slag discharge plate 204, so as to remove impurities from the fruits. The cleaned fruits will be conveyed to the second roller conveyor belt 4 through the diversion frame 3 for separate conveyance. When the fruits are conveyed to the cross plate 520, the electric telescopic rod 5 is started to move. 15 drives the pressing plate 516 to descend, so that the pressing plate 516 contacts the top of the fruit to fix the fruit. At this time, the fruit is squeezed by the film pressure sensor 517. The hardness of the fruit is judged by the pressure value monitored by the film pressure sensor 517, and the maturity of the fruit is judged according to the hardness of the fruit. The water pump 503 is started to spray the clean water in the water tank 502 from the nozzle 505 through the water pipe 504 to wash the fruit. At the same time, the second motor 508 is started to drive the first rotating rod 509 to rotate, and the first rotating rod 509 The rotation of the second pulley 512 drives the rotating drum 510 to rotate, and the rotation of the rotating drum 510 drives the brush plate 511 to rotate, brushing the surface of the fruit to remove stains on the surface of the fruit, and the waste water generated by the flushing will fall into the waste water tank 514 through the filter screen 513 for collection, and the color of the fruit is identified by the visual detection probe 507, and the maturity of the fruit is judged by the color. When the hardness and color of the fruit meet the maturity standard of the fruit, the third motor 518 drives the second rotating rod 519 to rotate, and the second rotating rod 519 is driven by the third motor 518 to rotate. The rod 519 drives the cross plate 520 to rotate, and the ripe fruits are rotated to the rear end of the second roller conveyor belt 4 through the rotation of the cross plate 520. When the fruits do not meet the maturity standard, the second rotating rod 519 drives the cross plate 520 to flip, and the unripe fruits are rotated to the outside of the second roller conveyor belt 4, so that the unripe fruits are discharged through the discharge port and the discharge frame 521, and the ripe fruits are conveyed along the second roller conveyor belt 4 to the inclined plate 8, and then discharged through the inclined plate 8, thereby achieving the purpose of sorting the fruits according to their maturity.

[0044] See also Figure 1-8On the basis of the above embodiment, in another embodiment of the present invention, preferably, a classification mechanism 6 is provided on one side of the second roller conveyor belt 4, and the classification mechanism 6 includes an adjusting rod 601, a slide groove 602, a bidirectional threaded rod 603, a moving block 604, a slider 605, and a partition 606.

The slider 605 is fixedly connected to the top of the bidirectional threaded rod 603 and is slidably connected to the inner wall of the slide groove 602. The partition 606 is fixedly connected to the inner wall of the second roller conveyor belt 4.

[0045] Preferably, the classification mechanism 6 also includes an air pump 607, an exhaust frame 608, a mesh plate 609, and a blanking plate 610.

[0046] Preferably, the number of the partitions 606 is four, and the four partitions 606 are evenly arranged on the inner wall of the second roller conveyor belt 4. By setting up multiple partitions 606, it is convenient to carry out multi-level classification according to the size of the fruit, which is convenient for subsequent sales.

[0047] Working principle: The two-way threaded rod 603 is driven to rotate by turning the knob. The rotation of the two-way threaded rod 603 will drive the two moving blocks 604 to rotate in the opposite direction, thereby driving one end of the adjusting rod 601 to swing through the slider 605 and the slide groove 602, and adjusting the distance between the two adjusting rods 601 at various positions. The distance between the two adjusting rods 601 above each partition 606 is gradually increased according to the size of the fruit, and the fruit rolling down from the inclined plate 8 will slide onto the two adjusting rods 601. When the size of the fruit is smaller than the distance between the two adjusting rods 601, it will fall onto the mesh plate 609, thereby achieving the purpose of classifying the fruit according to the size. By starting the air pump 607, air is sprayed from the mesh holes of the mesh plate 609 through the exhaust frame 608, and the falling fruit is blown, thereby reducing the falling force of the fruit and avoiding damage to the fruit caused by the falling fruit. The falling fruits of different sizes are collected separately through the blanking plate 610.
