[0002] After the fruits are picked, they are generally graded according to their size, color, etc. During the grading process, a special sorting device is needed to sort the fruits. The sorting device uses a color sensor to sort the fruits during the sorting process, but the existing sorting devices still have certain applicability defects during use. Patent publication number CN220277650U is a fruit intelligent grading and sorting device based on artificial intelligence machine vision. On the basis of the traditional visual recognition sorting and grading device, the device adds an intelligent host and a control system to the visual recognition device, making the device further in accuracy and recognition efficiency. At the same time, it simplifies the screening and diversion device structure of the reference patent, making it more convenient during work or maintenance. The above-mentioned device transports fruits through a conveyor belt. After the visual recognition device identifies inferior fruits, the inferior fruits will be removed from the upper end of the conveyor belt by a tossing arm. The tossing arm rotates horizontally at the upper end of the conveyor belt, and the fruits are horizontally transported at the upper end of the conveyor belt. The tossing arm uses its own inclined state to guide the fruits for discharge. In this process, the fruits transported behind the inferior fruits will be squeezed, and it is easy for good fruits and inferior fruits to be discharged at the same time. In addition, the transmission efficiency of the conveyor belt needs to be controlled, which can easily affect the sorting efficiency of the device.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In a specific embodiment, Figure 1-Figure 2As shown, in order to solve the problem of limited sorting efficiency of the existing device, the utility model includes a device body 1, and a conveyor belt 2 is arranged inside the device body 1; a discharge port 3 is fixedly installed on the outside of the device body 1, and a support plate 4 is fixedly installed on the upper end of the device body 1, and a color sensor 5 is fixedly installed inside the support plate 4; a sorting structure is arranged inside the support plate 4, and the sorting structure can achieve the effect of automatically removing inferior fruits. A driving motor 6 is arranged at the lower end of the sorting structure, and the driving motor 6 is fixedly installed on the upper end of the support plate 4, and an output shaft 7 is fixedly installed on the output end of the driving motor 6, and a fixed rod 8 is fixedly installed on the outside of the output shaft 7; two groups of sliding rods 9 are slidably installed inside the fixed rod 8, and a toggle plate 10 is fixedly installed on the end of the sliding rod 9 away from the fixed rod 8, and a connecting rod 11 is fixedly installed on the end of the toggle plate 10 close to the fixed rod 8, and the connecting rod 11 is located inside the other group of toggle plates 10.

[0025] When the fruit sorting device based on the color sensor is used, the fruits to be sorted are sorted through the conveyor belt 2. During this process, the color sensor 5 at the upper end of the support plate 4 will detect the color of the fruit surface. When it is detected that the fruit surface is damaged or partially rotten, the sorting structure will work and the problematic inferior fruits will be discharged from the discharge port 3. During this process, the driving motor 6 will drive the fixed rod 8 to rotate through the output shaft 7, and the fixed rod 8 will drive the toggle plate 10 to rotate through the sliding rod 9 and push the inferior fruits on the upper end of the conveyor belt 2 down, so that the inferior fruits are sorted out from the fruits. By changing the movement direction of the toggle plate 10 and the fruit, blockage in the fruit sorting process can be avoided, thereby improving the efficiency of the device in sorting fruits.

[0026] like Figure 1-Figure 7 As shown, in order to solve the problem that the existing device can only sort fruits of a single size, a fixed block 12 is fixedly installed on the outer side of the toggle plate 10, and a threaded rod 13 is installed through the inside of the fixed block 12, and a bevel gear 14 is fixedly installed on the outer side of the threaded rod 13. A driving rod 15 is rotatably installed inside the fixed rod 8, and a bevel gear 2 16 is fixedly installed on the end of the driving rod 15 close to the bevel gear 14, and the bevel gear 2 16 is meshed with the bevel gear 14, and a fixed gear 17 is fixedly installed on the end of the driving rod 15 away from the bevel gear 2 16, and a gear ring 18 is rotatably installed on the outer side of the output shaft 7, and the gear ring 18 is meshed with the fixed gear 17.

[0027] When the fruit sorting device based on the color sensor is used, the distance between the two groups of toggle plates 10 can be adjusted so that the toggle plates 10 are convenient for sorting fruits of different sizes. In this process, the ring gear 18 needs to be rotated, and the fixed gear 17 meshing with it is rotated during the rotation of the ring gear 18. During the rotation of the fixed gear 17, the bevel gear 2 16 is driven to rotate by the driving rod 15. At this time, the bevel gear 2 16 will drive the threaded rod 13 to rotate through the bevel gear 14. Then, the two groups of fixed blocks 12 can drive the two groups of toggle plates 10 away from each other, thereby changing the distance between the two groups of toggle plates 10. In this process, the connecting rod 11 will slide inside the toggle plate 10, and the sliding rod 9 will slide inside the fixed rod 8. By changing the distance between the two groups of toggle plates 10, the device can be suitable for sorting fruits of different sizes.

[0028] Based on the above embodiments, Figure 1-Figure 2 and Figure 8 As shown, in order to solve the problem that the existing device cannot automatically separate the size of fruits, a grading structure is provided on the outside of the device body 1, and the inside of the grading structure can achieve screening of fruits according to size. A guide plate 19 is provided inside the grading structure, and the guide plate 19 is fixedly installed on the outside of the device body 1, and a worm 20 is fixedly rotatably installed at the lower end of the guide plate 19, and a turntable 21 is fixedly installed at one end of the worm 20. A rotating shaft 22 is rotatably installed at the lower end of the guide plate 19, and a worm wheel 23 and a separation plate 24 are fixedly installed on the outside of the rotating shaft 22, and the worm wheel 23 is meshed and connected with the worm 20.

[0029] When the fruit sorting device based on color sensor is used, the conveyor belt 2 will convey the fruit to the upper end of the guide plate 19 and discharge it through the guide plate 19. In this process, the fruit can be graded by adjusting the spacing between the two groups of isolation plates 24. In this process, the turntable 21 needs to drive the worm 20 to rotate. During the rotation of the worm 20, the rotating shaft 22 will be driven to rotate through the worm wheel 23, and during the rotation of the rotating shaft 22, the isolation plate 24 will be driven to rotate, thereby changing the gap size between the two groups of isolation plates 24. After the isolation plates 24 are adjusted, small-sized fruits will fall through the gap between the two groups of isolation plates 24, while large-sized fruits will roll down from the end of the isolation plates 24, thereby completing the size grading process of the fruit by the device, effectively improving the convenience of using the device and increasing the overall practicality.
