[0026] When in use, the fruit material to be sorted is loaded onto the clamping roller 24 through the loading structure 12, and the first driving component 21 drives the chain 22 to rotate, thereby driving the mounting shaft 23 and the clamping roller 24 to move horizontally, so as to realize the transportation of the fruit material. When the fruit material is transported to the bottom of the camera recognition system 3, the camera recognition system 3 recognizes the fruit material. When the identified material to be sorted moves with the clamping roller 24 to the top opening of the spray valve 16, the spray valve 16 sprays airflow to blow the material to be sorted obliquely upward, and blows the material to be sorted into the limiting cover 15. The limiting cover 15 is blown by the spray valve 16. The material is limited, and at the same time, the buffer component 14 buffers and limits the material in the limiting cover 15 that flies to the top of the opening of the receiving groove 8, so that the material flying to the top of the opening of the receiving groove 8 is decelerated and falls into the receiving groove 8, and the water pump 5 draws the material in the second water tank 10 into the receiving groove 8, and the material that falls into the receiving groove 8 flows to the transition groove 13 with the water flow in the receiving groove 8, so as to realize the sorting of the material. At the same time, the water flowing in the receiving groove 8 buffers and protects the fallen material, avoids the situation that the material falls into the receiving groove 8 and is damaged due to collision, and effectively avoids the damage to the fruit material during the sorting process.

[0027] As a preferred embodiment of the present invention, the buffer component 14 is made of rubber, non-woven fabric or other materials. In this embodiment, the preferred buffer component 14 is made of rubber.

[0028] As a preferred embodiment of the present invention, a first material discharge chute 6 is provided at one end of the frame 1 for discharging materials that are not blown out by the spray valve 16 .

[0029] As a preferred embodiment of the present invention, a second discharge chute 7 is provided at one end of the transition chute 13 away from the receiving chute 8, and a partitioning mesh plate is installed inside the second discharge chute 7 to separate the material discharged into the second discharge chute 7 along with the water flow from the water flow.

[0030] As a preferred embodiment of the present invention, it also includes a first water tank 9, the interior of the first water tank 9 is connected with the interior of the second feeding chute 7, and is used to collect the water flow separated in the second feeding chute 7; the interiors of the first water tank 9 and the second water tank 10 are connected through a connecting water pipe 11, and the sorted materials and water flow flow into the second feeding chute 7 through the transition trough 13, and the partition mesh plate in the second feeding chute 7 separates the materials to complete the feeding of the sorted materials, and the water flow separated in the second feeding chute 7 is collected in the first water tank 9, so as to realize the reuse of water resources.

[0031] As a preferred embodiment of the present invention, the outer diameters of the two ends of the clamping roller 24 are smaller than the outer diameter of the middle position of the clamping roller 24; the positions where the ends of two adjacent clamping rollers 24 are close to each other form a receiving groove 25 for receiving the conveyed material.

[0032] As a preferred embodiment of the present invention, a gap is left between two adjacent installation shafts 23 , and the opening position of the spray valve 16 corresponds to the position of the receiving groove 25 , and the airflow sprayed by the spray valve 16 blows toward the material in the receiving groove 25 .

[0033] As a preferred embodiment of the present invention, the buffer components 14 are installed at intervals on the inner wall of the limit cover 15; the outer diameter of the buffer component 14 on the side close to the spray valve 16 is smaller than the outer diameter of the buffer component 14 on the side away from the spray valve 16, and the buffer component 14 with a small outer diameter first contacts the flying material in the limit cover 15 to perform preliminary buffering and deceleration on the material. After the preliminary deceleration, the material contacts the buffer component 14 with a large outer diameter, thereby realizing multi-layer buffering and deceleration of the material, and the buffering and deceleration effect is better, ensuring that the material will not collide with the inner wall of the limit cover 15, and also ensuring that the material can effectively fall into the receiving groove 8.

[0034] As a preferred embodiment of the present invention, it also includes a material turning mechanism 4 for turning the material conveyed to the bottom of the camera recognition system 3.

[0035] As a preferred embodiment of the present invention, the material turning mechanism 4 includes a flexible belt 41 installed inside the frame 1 through a mounting roller 43, and the flexible belt 41 is located at the bottom of the camera recognition system 3 and the clamping roller 24; it also includes a second driving component 42 for driving the mounting roller 43 and the flexible belt 41 to rotate.

[0036] As a preferred embodiment of the present invention, the flexible belt 41 is made of rubber, silicone or other materials. In this embodiment, the flexible belt 41 is preferably made of rubber.

[0037] As a preferred embodiment of the present invention, it also includes a positioning component 44, which is used to limit the side of the flexible belt 41 close to the clamping roller 24, so that the side of the flexible belt 41 close to the clamping roller 24 is in contact with the bottom of the clamping roller 24. When the clamping roller 24 and the material move to the bottom of the camera recognition system 3, the second driving component 42 drives the mounting roller 43 and the flexible belt 41 to rotate, and because the top of the flexible belt 41 is in contact with the bottom of the clamping roller 24, the rotation of the flexible belt 41 drives the clamping roller 24 to rotate, and the rotating clamping roller 24 drives the material in the receiving groove 25, so that the material in the receiving groove 25 is flipped, ensuring that the camera recognition system 3 fully recognizes the material and improves the sorting effect.

[0038] When in use, the fruit material to be sorted is loaded onto the clamping roller 24 through the loading structure 12, and the first driving component 21 drives the chain 22 to rotate, thereby driving the mounting shaft 23 and the clamping roller 24 to move horizontally, so as to realize the transportation of the fruit material. When the fruit material is transported to the bottom of the camera recognition system 3, the camera recognition system 3 recognizes the fruit material. When the identified material to be sorted moves with the clamping roller 24 to the top opening of the spray valve 16, the spray valve 16 sprays airflow to blow the material to be sorted obliquely upward, and blows the material to be sorted into the limiting cover 15. The limiting cover 15 limits the material blown up by the spray valve 16. At the same time, the buffer component 14 buffers and limits the material in the limiting cover 15 that flies to the top opening of the receiving groove 8, so that the flying The materials at the top of the receiving trough 8 are decelerated and fall into the receiving trough 8, and the water pump 5 pumps the materials in the second water tank 10 into the receiving trough 8. The materials falling into the receiving trough 8 flow to the transition trough 13 with the water flow in the receiving trough 8, so as to realize the sorting of the materials. At the same time, the water flowing in the receiving trough 8 buffers and protects the falling materials, so as to prevent the materials from being damaged due to collision when falling into the receiving trough 8, and effectively avoids the damage to the fruit materials during the sorting process; the sorted materials and water flow through the transition trough 13 and fall into the second unloading trough 7, and the partition mesh plate in the second unloading trough 7 separates the materials to complete the unloading of the sorted materials, and the separated water flow in the second unloading trough 7 is collected in the first water tank 9, so as to realize the reuse of water resources.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
