Referring to FIGS. 1-6, an embodiment of the present application provides a , including an operating table 1, one side of the operating table 1 is xedly connected to a servo motor I 2, an output end of the servo motor I 2 is xedly connected to a driving roller 3, a top of the operating table 1 is rotatably connected to a driven roller 4, a conveyor belt 22 for conveying fruits is drivingly connected between the driving roller 3 and the driven roller 4, a plurality of blocking strips 23 are xedly connected to an outer side of the conveyor belt 22, the top of the operating table 1 is xedly connected to an auxiliary roller 24, the outer side of the auxiliary roller 24 is drivingly connected to an inner side of the conveyor belt 22, and two detection and sorting mechanisms are arranged at the top of the operating table 1; and a plurality of collection mechanisms are arranged on an outer side of the operating table 1, the servo motor I 2 drives the driving roller 3, the driven roller 4 and the conveyor belt 22 to rotate, causing the conveyor belt 22 to convey tomato fruits at a uniform speed through the plurality of blocking strips 23 on the outer side. Referring to FIG. 1, FIG. 4 and FIG. 6, the detection and sorting mechanisms include two xing columns I 5, a bearing frame 6 is xedly connected to a top of the xing column I 5, one side of the bearing frame 6 is xedly connected to a visual detection camera body 7, the other side of the bearing frame 6 is xedly connected to a servo motor II 8, an output end of the servo motor II 8 is xedly connected to a turntable 9, an outer side of the turntable 9 is rotatably connected to a bottom of the bearing frame 6, and the outer side of the turntable 9 is xedly connected to a plurality of stirring meshes 10. The top of the operation table 1 is xedly connected to two xing columns II 11, an outer side of the xing column II 11 is xedly connected to an electric push rod 12, one side of the electric push rod 12 is xedly connected to a push plate 13, and an outer side of the push plate 13 is slidably connected to a top of the xing column II 11. One side of the push plate 13 is xedly connected to a servo motor III 14, and an output end of the servo motor III 14 is xedly connected to a rubber dish 15. The tomato fruits are detected through the visual detection camera body 7. After discovering tomato fruits of poor quality, the servo motor II 8 drive the turntable 9 and the stirring meshes 10 to rotate, stirring them out of the top of the conveyor belt 22. Moreover, the electric push rods 12 are utilized to push the push plates 13, driving the servo motors III 14 and the rubber dishes 15 to clamp the tomato fruit, and the servo motors III 14 drive the rubber dishes 15 and turn over the tomato fruits, causing the tomato fruits to be conveyed by the conveyor belt 22 for a second detection. Referring to FIG. 1, FIG. 3 and FIG. 5, the collection mechanisms include two blanking plates I 16, one side of the blanking plate I 16 is xedly connected to a top of the operating table 1, a top of the blanking plate I 16 is xedly connected to two blocking plates 17, one side of the operating table 1 is xedly connect to a blanking plate II 25, outer frames 18 are arranged at bottoms of the blanking plates I 16 and the blocking plates 17, and the outer frames 18 are arranged on outer sides of the operating table 1. An inner side of the outer frame 18 is xedly connected to a plurality of telescopic rods 19, and springs 20 are sleeved on outer sides of the telescopic rods 19. Tops of the telescopic rods 19 are xedly connected to a collection basket 21, and a bottom of the collection basket 21 is xedly connected to tops of the springs 20. The tomato fruits of poor quality are guided by the blanking plate I 16 and the blocking plates 17, causing the rolling tomato fruits to move into the collection basket 21 at the top of the outer frame 18, while the good tomato fruits roll into another collection basket 21 through the blanking plate II 25. When the tomato fruits roll into the collection baskets 21, the impact force between the collection baskets 21 and the tomato fruits is cushioned by the plurality of telescopic rods 19 and springs 20 at the bottom of the collection baskets 21, causing the tomato fruits to fall intact into the collection baskets 21. Moreover, when the collection baskets 21 are not replaced in time, after too many tomato fruits have accumulated inside the collection baskets 21, the collection baskets 21 will move downward inside the outer frames 18, thereby increasing the volume of the collection baskets 21, and preventing the tomato fruits from falling onto the ground. An operating principle of the present invention is as follows. During the inspection of the tomato fruits, the cleaned tomato fruits are rst conveyed to the top of the conveyor belt 22 one by one, causing each tomato to be placed between two blocking strips 23. Under the rotation of the driving roller 3, the driven roller 4 and the conveyor belt 22 driven by the servo motor I 2, and with the support of the three auxiliary rollers 24, the tomatoes on the top of the conveyor belt 22 can be conveyed to one side. When the tomatoes pass through the rst xing column I 5 and are detected by the visual detection camera body 7 on one side of the bearing frame 6, the servo motor I 2 will drive the conveyor belt 22 and the blocking strips 23 to move them directly below the bearing frame 6 after discovering tomato fruits of poor quality, and the servo motor II 8 drives the turntable 9 and the stirring meshes 10 to rotate, and sweeps them to one side of the blanking plate I 16, so that the tomato fruits can roll to the top of the blanking plate I 16. Under the shelter of the blocking plate 17, the tomato fruits can roll along the blanking plate I 16 to the collection basket 21 at the top of one side of the outer frame 18, and the servo motor I 2 continues to drive the conveyor belt 22 and the blocking strips 23 to convey the tomato fruits. When the tomato fruits move to the middle of the two xing columns II 11, the two electric push rods 12 push the push plates 13, driving the servo motors III 14 and the rubber dishes 15 to clamp the tomato fruits. When the tomato fruit is clamped by the two rubber dishes 15, the two servo motors III 14 drive the tomato fruit to rotate, causing the tomato fruit to turn over, and the two electric push rods 12 drive the push plates 13 to move backward, causing the tomato fruit to continue to be conveyed backward at the top of the conveyor belt 22 and the blocking strips 23 after being turned over. Secondary detection is performed through the second visual detection camera body 7 for secondary sorting. The detected tomato fruits are rolled into the collection basket 21 through the blanking plate II 25 on one side of the conveyor belt 22. When the number of tomato fruits inside the collection basket 21 gradually increases, the collection basket 21 presses the plurality of telescopic rods 19 and springs 20 at the bottom under the action of weight, causing the collection basket 21 to move downward when the tomato fruits are loaded too much, thereby ensuring better collection of the tomato fruits.
