[0002] In the fruit and vegetable processing and logistics industry, the sorting efficiency and quality of spherical fruits and vegetables have always been key factors affecting the industry's development. Traditional manual sorting methods rely on workers' experience and physical strength, which is not only inefficient but also prone to inaccurate sorting due to factors such as human fatigue, making it difficult to meet the precision requirements of large-scale processing and transportation. With the continuous growth of fruit and vegetable production and the increasingly stringent market standards for fruit and vegetable quality control, the drawbacks of traditional sorting models are becoming increasingly apparent.
[0003] In recent years, although automated sorting equipment has been gradually put into use, existing equipment still has many problems. For example, some equipment cannot effectively achieve single-layer arrangement of fruits and vegetables in the feeding stage, and fruits and vegetables are prone to stacking during the conveying process. This not only leads to errors and omissions in subsequent sorting processes, but may also cause mechanical damage to fruits and vegetables, affecting their appearance quality and economic value.
[0004] In summary, existing spherical fruit and vegetable sorting equipment has many shortcomings in terms of feeding, preventing stacking, preventing damage, and connecting with subsequent sorting processes. It is difficult to meet the comprehensive requirements of modern fruit and vegetable processing industry for sorting efficiency, quality, and environmental protection. There is an urgent need to develop a new type of automatic sorting device that can effectively solve the above problems.

[0041] Example 1:
[0042] Combined with appendix Figures 1-3 6. An automatic sorting device, comprising a feeding device 1, a guide plate 2, and a screening device 3; the feeding device 1 is used to automatically convey spherical fruits and vegetables to the screening device 3.
[0043] Specifically, the main function of the feeding device 1 is to automatically convey the spherical fruits and vegetables to be sorted to the screening device 3.
[0044] Specifically, the feeding device 1 consists of a frame 1-1, a conveyor belt 1-2, and feeding levers 1-3. The frame 1-1 includes an interconnected inclined feeding section and a horizontal conveying section. Inside the frame 1-1, the conveyor belt 1-2, adapted to the inclined feeding section and the horizontal conveying section, is installed. A motor for driving the conveyor belt 1-2 is also installed on one side of the frame 1-1. Multiple feeding levers 1-3 are spaced apart along the conveying direction of the conveyor belt 1-2. Furthermore, a collection bin 1-4 is installed at the feed end of the inclined feeding section of the frame 1-1.
[0045] During the loading process, the spherical fruits and vegetables to be sorted are first placed in the collection bin 1-4. Under the influence of the collection bin 1-4, the spherical fruits and vegetables will automatically roll towards the conveyor belt 1-2. At this time, the motor starts and drives the conveyor belt 1-2, which in turn moves the feeding lever 1-3. Driven by the feeding lever 1-3, the spherical fruits and vegetables can move upwards along the inclined loading section. The purpose of setting up the inclined loading section is to ensure that the spherical fruits and vegetables are arranged in a single layer on the conveyor belt 1-2. When there is a stack of spherical fruits and vegetables, the upper fruits and vegetables will automatically roll down due to gravity, thus creating favorable conditions for subsequent sorting processes.
[0046] Furthermore, multiple portal frames 1-6 are spaced apart in the horizontal conveying section of frame 1-1. Multiple chains 1-7 are suspended from the crossbeams of the portal frames 1-6 along their length. The main function of these chains 1-7 is to provide resistance to the stacked spherical fruits and vegetables, further preventing them from piling up; and at the same time, avoiding damage to the spherical fruits and vegetables.
[0047] In addition, brackets 1-5 are installed at both ends of the feeding rods 1-3 on the belt surface of conveyor belt 1-2, as shown in the attached diagram. Figure 6 As shown, the feeding rod 1-3 and the bracket 1-5 are connected by a rotating mechanism. This design effectively reduces friction between the feeding rod 1-3 and spherical fruits and vegetables, thus better preventing damage to them.
[0048] It is important to note that a certain distance must be maintained between chain 1-7 and the material guide bar 1-3. This is to prevent chain 1-7 from colliding with the material guide bar 1-3 during the operation of conveyor belt 1-2, which would generate unnecessary noise.
[0049] A guide plate 2 is connected to the discharge end of the feeding device 1. The guide plate 2 has multiple diversion baffles spaced apart inside, and is set at an angle. Its working principle is based on the gravity of the spherical fruits and vegetables, causing them to roll automatically. The guide plate 2 and its internal diversion baffles enable the spherical fruits and vegetables to roll sequentially in a certain order, thereby improving the accuracy of subsequent sorting.
[0050] The discharge end of the guide plate 2 is connected to a screening device 3, which classifies spherical fruits and vegetables according to their size. The screening device 3 can be any commercially available equipment capable of screening by size.
[0051] Example 2:
[0052] Combined with appendix Figure 1 , 2In addition to embodiments 4 and 5, this utility model also provides an automatic sorting device, the main difference from embodiment 1 lies in the specific structure of the screening device 3. Based on embodiment 1, the screening device 3 includes a fixed frame 3-1, a fan-shaped frame 3-2, and guide rods 3-3. The fan-shaped frame 3-2 is mounted on the top of the fixed frame 3-1, and the smaller end of the fan-shaped frame 3-2 is higher than the larger end. This design is to allow spherical fruits and vegetables to automatically roll along the fan-shaped frame 3-2 under their own weight. Inside the fan-shaped frame 3-2, multiple guide rods 3-3 are installed at intervals along the circumferential direction. The distance between two adjacent guide rods 3-3 at the smaller end of the fan-shaped frame 3-2 is smaller than the distance at the other end. When spherical fruits and vegetables roll along the guide rods 3-3, if the distance between two guide rods 3-3 is greater than the diameter of the spherical fruits and vegetables, the spherical fruits and vegetables will automatically fall from that distance. Below the fan-shaped frame 3-2, multiple arc-shaped guide channels 3-4 are installed. The walls of adjacent arc-shaped guide channels 3-4 fit tightly together, and the arc-shaped guide channels 3-4 are firmly connected to the fixing frame 3-1. When spherical fruits and vegetables fall between two guide rods 3-3, they will accurately fall into the corresponding arc-shaped guide channel 3-4. A material basket for collecting spherical fruits and vegetables of the corresponding size is placed at the discharge end of the arc-shaped guide channel 3-4. After sorting, the spherical fruits and vegetables slide along the arc-shaped guide channel 3-4 into the corresponding material basket, thus completing the entire sorting process.
[0053] Furthermore, the larger end of the fan-shaped frame 3-2 is hinged to the fixed frame 3-1, while the smaller end of the fan-shaped frame 3-2 is elastically connected to the fixed frame 3-1 via a spring 3-5. A drive motor 3-6 is installed inside the fixed frame 3-1, and its output is connected to an eccentric turntable 3-8. The eccentric turntable 3-8 is hinged to a connecting rod 3-7, the other end of which is hinged to the smaller end of the fan-shaped frame 3-2. The operation of the drive motor 3-6 causes the smaller end of the fan-shaped frame 3-2 to sway up and down. This design aims to facilitate the smooth rolling of spherical fruits and vegetables along the guide rod 3-3, preventing them from getting stuck inside the fan-shaped frame 3-2 and thus avoiding accumulation.
[0054] During actual operation, it is necessary to carefully control the eccentricity between connecting rod 3-7 and the output shaft of drive motor 3-6. This is to ensure that the smaller end of the fan-shaped frame 3-2 remains higher than the larger end when it shakes up and down, preventing spherical fruits and vegetables from rolling backward. At the same time, it is also necessary to properly control the speed of drive motor 3-6 to avoid excessive shaking of the fan-shaped frame 3-2. Otherwise, spherical fruits and vegetables may bounce violently on connecting rod 3-7, affecting the sorting effect.
[0055] Furthermore, a rubber pad is laid inside the arc-shaped guide channel 3-4. This is to prevent spherical fruits and vegetables from colliding violently with the arc-shaped guide channel 3-4 when they fall into it, thus avoiding damage to the fruits and vegetables.
[0056] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
