[0024] Please refer to the appendix. Figures 1-5 This utility model provides a fruit picking and sorting machine, including a first sorting box 1, a first support 2 vertically fixed at the bottom corner of the first sorting box 1, a fruit adding port 3 fixedly connected to the top of the first sorting box 1, and a second sorting box 4, a second support 5 vertically fixed at the bottom corner of the second sorting box 4, the second sorting box 4 being located below the first sorting box 1, both the first sorting box 1 and the second sorting box 4 are provided with vibrating sorting components, both the bottom of the first sorting box 1 and the bottom of the second sorting box 4 are provided with small fruit collecting components, a fruit conveying component is provided between the first sorting box 1 and the second sorting box 4, and a large fruit collecting component is also provided at the bottom of the second sorting box 4;
[0025] The vibrating screening assembly includes two screening boxes 6, which are located in the first screening box 1 and the second screening box 4 respectively. The bottom of each screening box 6 is inclined, and a number of screening holes 7 are evenly opened at the bottom of the screening box 6. The diameter of the screening holes 7 is arranged from small to large, which is used to screen small-volume fruits and large-volume fruits.
[0026] The vibrating screening assembly also includes a support plate 8, which is horizontally fixed to both sides of the inner wall of the first screening box 1 and both sides of the inner wall of the second screening box 4. A servo motor 9 is fixed to the top of each support plate 8, and a rotating shaft 10 is fixed to the output shaft of the servo motor 9. Two cams 11 are fixed to the surface of each rotating shaft 10. End plates 12 are fixed to the four corners of the screening box 6. Limiting holes 13 are vertically opened in the center of each end plate 12, and limiting rods 14 are vertically inserted into each limiting hole 13. The bottom ends of the limiting rods 14 are fixed to the top of the support plate 8, and springs 15 are sleeved on the surface of each limiting rod 14. The top ends of the springs 15 are fixed to the bottom of the end plate 12, and the bottom ends of the springs 15 are fixed to the support plate. 8. Connecting plates 16 are fixed to the top and side of the end plate 12. Cams 11 and connecting plates 16 correspond to each other. Cams 11 can abut against the lower surface of the corresponding connecting plate 16. Specifically, when the servo motor 9 is running, it can drive the cams 11 to rotate through the rotating shaft 10. When the cams 11 rotate, they can intermittently push the support plate 8. When the support plate 8 is pushed up, it drives the screening box 6 to move up and stretches the spring 15. When the support plate 8 and the screening box 6 move down under the action of gravity, the spring 15 is compressed. The elastic force of the spring 15 can effectively prolong the up and down swaying of the screening box 6, so that the fruit in the screening box 6 is vibrated and can be screened by several screening holes 7.
[0027] The small fruit collection assembly includes a first feeding hopper 17. The top of the first feeding hopper 17 is fixedly connected to the bottom of the first screening box 1 on the side away from the second screening box 4. The bottom of the first feeding hopper 17 is fixedly connected to a feeding pipe 18, which is spiral in shape. A first small fruit collection box 19 is placed below the feeding pipe 18. Specifically, small-volume fruits that have been vibrated and screened in the screening box 6 located in the first screening box 1 can be collected by the first feeding hopper 17 and then spirally fed into the first small fruit collection box 19 through the feeding pipe 18 for collection.
[0028] The fruit conveying assembly includes a second feeding hopper 20. The top of the second feeding hopper 20 is fixedly connected to the bottom of the first screening box 1, and the bottom of the second feeding hopper 20 is fixed to the top of the second screening box 4. The bottom of the second feeding hopper 20 extends into the interior of the second screening box 4. Specifically, large-volume fruits that have been vibrated and screened in the screening box 6 located in the first screening box 1, as well as small-volume fruits that have not yet been screened out, can be fed into the screening box 6 located inside the second screening box 4 through the second feeding hopper 20 for secondary vibrating screening.

A second small fruit collection box 22 is placed below the third feeding hopper 21. Specifically, small-volume fruits that have been vibrated and screened twice in the screening box 6 located in the second screening box 4 can be fed into the second small fruit collection box 22 through the third feeding hopper 21 for collection.
[0030] The large fruit collection component includes a fourth hopper 23, the top of which is fixedly connected to the bottom of the second screening box 4. A large fruit collection box 24 is placed below the fourth hopper 23. Specifically, large-volume fruits that have undergone secondary vibration screening in the screening box 6 located in the second screening box 4 can be fed into the large fruit collection box 24 through the fourth hopper 23 for collection.
[0031] It should be noted that this utility model is electrically connected to an external main controller and 220V AC mains power, and the main controller can be an existing technology device that controls switches, etc.
[0032] The usage process of this utility model is as follows: First, the operator controls the servo motor 9 to start vibrating the screening box 6 located in the first screening box 1 and the second screening box 4. Then, the operator adds the harvested fruit into the screening box 6 in the first screening box 1 through the fruit inlet 3. Small fruits that have been vibrated and screened in the screening box 6 within the first screening box 1 can be collected through the first feeding hopper 17, and then spirally fed into the first small fruit collection box 19 through the feeding pipe 18. Large fruits that have been vibrated and screened in the screening box 6 within the first screening box 1, as well as small fruits that have not yet been screened, can be collected through the first feeding hopper 17. The second hopper 20 discharges the fruit into the screening box 6 located inside the second screening box 4 for secondary vibration screening. Small-volume fruits after secondary vibration screening in the screening box 6 inside the second screening box 4 can be discharged into the second small fruit collection box 22 via the third hopper 21 for collection. Large-volume fruits after secondary vibration screening in the screening box 6 inside the second screening box 4 can be discharged into the large fruit collection box 24 via the fourth hopper 23 for collection. That is, this utility model can perform secondary vibration screening and separation of harvested fruits, thereby better separating large-volume fruits from small-volume fruits and making the screening more thorough.
