[0002] Fruit sorting is an important agricultural product processing process that involves classifying harvested fruits according to different standards. This link is crucial to increasing the overall value of fruits, meeting market requirements and ensuring consumer satisfaction.

[0003] After the existing fruit sorting device completes sorting of medium and large fruits, the fruits fall into the fruit collection bag through the discharge end of the conveyor for packaging. However, since the fruits fall into the collection bag directly perpendicular to the bag opening, when there are fruits collected at the bottom of the collection bag, the subsequent fruits are easily damaged by the previously collected fruits during the collection process, thereby affecting the normal sale of the fruits. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide an automatic fruit sorting device to solve the technical problem in the prior art that fruits are easily damaged when they fall vertically into a collection bag, thereby affecting the normal sale of fruits.

[0035] Furthermore, the term "identical" does not necessarily mean that the structures must be identical; slight variations are permitted. The term "perpendicular" simply means that the positional relationship between the structures is more perpendicular than "parallel," not that the structures must be perfectly vertical; rather, they can be slightly tilted.

[0036] See also Figure 1 、 Figure 2 and Figure 5 The utility model provides a technical solution: an automatic fruit sorting device, comprising a first conveyor, wherein a collecting frame 9 is rotatably connected to the unloading end of the first conveyor 2, and a cylinder 10 for adjusting the angle of the collecting frame 9 when collecting fruits is rotatably connected to the frame of the first conveyor 2, wherein the model of the cylinder 10 is MAL63B-X500;

[0037] The collecting frame 9 is a rectangular frame structure, and two hanging racks are relatively provided on the top of the collecting frame 9, and the hanging racks are used to hang collection bags for collecting fruits.

[0038] Two telescopic rods are relatively arranged at the bottom of the collecting frame 9, and the bottoms of the two telescopic rods are commonly connected to a base 12, and a weighing component for weighing fruits is arranged on the base 12.

[0039] In this solution, a collection bag for collecting fruits is placed in the collection frame 9, and the collection bag is hung on the hanging rack. The collection frame 9 is initially tilted so that the bag opening of the collection bag is tilted toward the conveyor belt of the first conveyor 2. When the sorted fruits are transported by the first conveyor 2 to the discharge end, the fruits can be tilted and rolled down to be collected in the collection bag. Compared with fruits directly falling vertically into the collection bag, collisions between fruits can be reduced.

[0040] As the fruits are collected into the collection bag, the fruits in the collection bag are weighed by the weighing assembly. When the collected fruits reach a certain weight, the cylinder 10 pulls the collection frame 9 to move, causing the collection frame 9 to swing horizontally. At this time, the collection bag is in a vertical state to collect more fruits in the collection bag.

[0041] See also Figure 1 、 Figure 2 and Figure 5 In this embodiment, the weighing assembly includes a bottom plate 13 that is slidably connected to the inside of the bottom bracket 12. A number of springs 14 are installed between the bottom plate 13 and the bottom wall of the bottom bracket 12. A first weighing sensor 15 is fixedly connected to the bottom wall of the bottom bracket 12. The model of the first weighing sensor 15 is QB-16-100. The first weighing sensor 15 is located on the movement trajectory of the bottom plate 13.

[0042] In this solution, when the fruits are collected into the collection bag, the fruits press down the bottom plate 13, and relative sliding occurs between the bottom plate 13 and the bottom support 12. When the bottom plate 13 slides down and acts on the detection end of the first weighing sensor 15, the first weighing sensor 15 weighs the fruits collected in the collection bag. When the collected fruits reach a certain weight, the cylinder 10 pulls the collection frame 9 to move, so that the collection frame 9 tends to swing horizontally. At this time, the collection bag is in a vertical state to collect more fruits in the collection bag. When the collection bag containing the fruits is taken out, the bottom plate 13 is reset under the force generated by the deformation of the spring 14 back to its original state, waiting for the next collection of fruits.

[0043] See also Figure 1 and Figure 7 In this embodiment, the telescopic rod includes a first rod body 16 fixedly connected to the collection frame 9, and a second rod body 17 inserted in the first rod body 16, one end of the second rod body 17 extending out of the first rod body 16 is fixedly connected to the base 12, and a tension spring 18 is installed between the end of the second rod body 17 extending into the first rod body 16 and the inner wall of the first rod body 16, and the deformation coefficient of the spring 14 is smaller than the deformation coefficient of the tension spring 18.

[0044] In this solution, when the fruit is collected into the collection bag, the fruit first presses down the bottom plate 13. When the bottom plate 13 is compressed and squeezes the spring 14 and contacts the detection end of the first weighing sensor 15, the bottom support 12 continues to move downward under the pressure of the fruit. When the bottom support 12 moves downward, it drives the second rod 17 to move. When the second rod 17 moves downward and extends out of the first rod 16, it stretches the tension spring 18. The deformation of the tension spring 18 can play a buffering role, thereby avoiding a large impact force between the fruit and the bottom plate 13 when the fruit is collected in the collection bag, thereby reducing damage to the fruit.

[0045] See also Figure 3 and Figure 6 In this embodiment, the hanging rack includes a vertical portion 19 and a horizontal portion 20 , the vertical portion 19 is fixedly connected to the collection frame 9 , and a limiting plate 21 is vertically inserted into the horizontal portion 20 .

[0046] In this solution, the hanging rack is integrally formed by the vertical part 19 and the horizontal part 20, similar to the shape of a "7". The collection bag can be hung on the collection frame 9 through the hanging rack, and after the hanging is completed, the limiting plate 21 slides down to contact the collection frame 9, which can limit and block the collection bag, thereby ensuring that the collection bag is stably hung on the collection frame 9.

[0047] See also Figure 3 and Figure 6In this embodiment, a through hole 22 is opened on the surface of the limiting plate 21 to pass through the limiting plate 21, and a limiting bolt 23 is threadedly connected to the horizontal portion 20, and the screw portion of the limiting bolt 23 is passed through the through hole 22.

[0048] In this solution, when the limiting bolt 23 is screwed onto the horizontal portion 20, the screw portion of the limiting bolt 23 is passed through the through hole 22, thereby limiting the limiting plate 21 and preventing the limiting plate 21 from being separated from the mounting bracket and lost.

[0049] See also Figure 2 In this embodiment, a guide plate 24 is fixedly connected to the frame of the first conveyor 2 , and the guide plate 24 is located above the collecting frame 9 .

[0050] In this solution, the guide plate 24 supports and guides the fruit when the fruit rolls down and is collected into the collection bag, ensuring that the fruit falls gently and accurately into the collection bag.

[0051] See also Figure 1 、 Figure 2 and Figure 4 , further comprising at least one second conveyor 1 perpendicular to the conveying direction of the first conveyor 2, the feed end of the first conveyor 2 being close to the second conveyor 1, and the conveying space at the top of the first conveyor 2 being connected to the conveying space at the top of the second conveyor 1;

[0052] A sorting assembly for sorting fruits is installed on the frame of the second conveyor 1, and the sorting assembly is directly opposite to the connection between the conveying spaces of the first conveyor 2 and the second conveyor 1;

[0053] A second weighing sensor 3 is provided below the conveyor belt of the second conveyor 1. The model of the second weighing sensor 3 is QB-16-10. An image collector 4 and a distance sensor 5 are installed on the frame of the second conveyor 1. The image collector can be a camera with the model DS-2AM1-613X. The model of the distance sensor 5 is HL-G2.

[0054] The system further includes a controller 25 , which is electrically connected to the image collector 4 , the distance sensor 5 , and the sorting component.

[0055] When the automatic fruit sorting device of the present invention is in use, the fruits are transferred one by one via the feeding table and transported to the conveyor belt of the second conveyor 1. When the fruits are transported by the second conveyor 1 to the connection with the conveying space of the first conveyor 2, the fruits block the energy waves emitted by the distance sensor 5. At this time, the distance sensor 5 cannot receive the reflected signal, and the second conveyor 1 stops transporting the fruits. At this time, the fruits enter the detection area, and then the image collector 4 collects images of information such as the glossiness and appearance of the fruits, and the second weighing sensor 3 detects the weight of the fruits, and sends the collection and detection results to the controller 25 in the form of electrical signals. The controller 25 analyzes the collected image information and detection results to determine whether the fruits meet the sorting standards at that location.

[0056] If the fruit meets the sorting criteria, the controller 25 sends an instruction to the sorting component to perform sorting, and the fruit is sorted to the first conveyor 2, and the fruit is further transported and collected by the first conveyor 2;

[0057] If the controller 25 determines that the fruit does not meet the sorting criteria at that location, the fruit continues to be conveyed downstream through the second conveyor 1, and continues to be judged until the fruit meets the sorting criteria. When the fruit meets the sorting criteria, the sorting components at other locations on the second conveyor 1 sort the fruit to the corresponding conveyor. In this way, the automatic fruit sorting device of the present invention can identify and sort the fruit according to its appearance characteristics such as weight and glossiness, making the fruit sorting work more refined.

[0058] See also Figure 1 、 Figure 2 and Figure 4 In this embodiment, the sorting component includes a mounting plate 6 fixedly connected to the top of the second conveyor 1, the mounting plate 6 is fixedly connected to the image collector 4, and an electric push rod 7 is also fixedly connected to the mounting plate 6. The model of the electric push rod 7 is DG4T, and the output end of the electric push rod 7 is fixedly connected to a push plate 8, and the generating end of the ranging sensor 5 is facing the push plate 8.

[0059] In this solution, when the fruit needs to be sorted, the controller 25 controls the action of the electric push rod 7, and the electric push rod 7 pushes the push plate 8 close to the fruit, and pushes the fruit from the conveying space of the second conveyor 1 into the conveying space of the first conveyor 2 to realize the sorting of the fruit.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
