Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, specifically to a sorting device for tuberous root crops. Background Technology

[0002] With the continued acceleration of agricultural modernization, the agricultural production sector is undergoing profound changes, with increasingly higher demands for crop harvesting efficiency and quality. Root crops, such as the widely cultivated and popular potato, the nutritious sweet potato, and the emerging tiger nut, have firmly established themselves as crucial players in the global agricultural production landscape.

[0003] The emergence of mechanized harvesting methods has improved harvesting efficiency to some extent. However, when faced with tuberous root crops of different sizes, shapes, and qualities, existing mechanical sorting equipment often falls short, unable to accurately classify and screen them according to pre-set standards. In addition, due to the unique growth habits of tuberous root crops, their long-term deep burial in the ground inevitably results in a large amount of soil adhering to the crop surface, and even during harvesting, soil clods of similar size to the crop may be mistakenly dug up along with it.

[0004] Chinese patent CN110122037A discloses an integrated harvesting and sorting machine for tuberous root crops, which uses thin ropes with varying gaps as sorting tools. This device does demonstrate certain sorting advantages, effectively separating crops of different sizes. However, it proves ineffective when dealing with tuberous root crops covered in clumps of soil, especially those clumps the same size as the crop itself. Because the thin ropes cannot accurately distinguish the material differences between the soil clumps and the crop, and cannot effectively separate them through simple gap filtering, the harvested crop product still contains numerous soil clumps and impurities. Utility Model Content

[0005] To address the above problems, this utility model proposes a sorting device for tuberous root and rhizome crops, the specific technical solution of which is as follows:

[0006] A sorting device for tuberous root crops includes a first visual detection component and a second visual detection component. Both the first and second visual detection components use pulsed LEDs for imaging. The detection surfaces of the first and second visual detection components are arranged facing each other to form a feed inlet. Below the feed inlet, from top to bottom, are arranged a soil clod sorting component consisting of a soil clod sorting control console and a soil clod diversion plate, a defective product sorting component consisting of a defective product sorting control console and a defective product diversion plate, and a good product sorting component consisting of a good product sorting control console and a good product diversion plate. The soil clod sorting control console, defective product sorting control console, and good product sorting control console are arranged sequentially from top to bottom. Arranged below the first vision inspection component, the soil clod diversion plate, the defective product diversion plate, and the good product diversion plate are arranged sequentially from top to bottom below the second vision inspection component. A premium product diversion platform is provided below the good product diversion plate. Each sorting component's control panel has a lever assembly on the side near the diversion plate for diverting materials to the diversion plate. Premium products can fall from the inlet to the premium product diversion platform. The first vision inspection component is communicatively connected to the second vision inspection component, the soil clod sorting control panel, the defective product sorting control panel, and the good product sorting control panel.

[0007] Furthermore, a premium product buffer plate is provided on the lower side of the good product sorting control console, a soil block buffer plate is provided below the second vision detection component, a defective product buffer plate is provided below the soil block diversion plate, and a good product buffer plate is provided below the defective product buffer plate.

[0008] Furthermore, in any sorting assembly, there are multiple sets of lever assemblies, arranged at intervals along the front-to-back direction. Each lever assembly includes a lever and a motor, which are connected by multiple connecting rods. The lever can extend under the drive of the motor and thus lie horizontally between the sorting control console and the deflector plate.

[0009] Furthermore, each buffer plate has a rubber layer on its surface.

[0010] Furthermore, the end of the drainage plate closest to its corresponding control panel is higher than the other end.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. By using pulsed LED double-sided detection, the characteristics and volume of objects can be obtained, thus achieving comprehensive detection of objects. Based on the quality and damage of tuberous root crops, materials are divided into clods, substandard products, good products, and superior products. Instructions are then issued to each sorting component for sorting, avoiding the drawback of traditional sorting equipment being unable to separate clods, while improving sorting accuracy.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] The present invention provides the following specific implementation scheme:

[0022] like Figure 1-4 As shown, this utility model provides a sorting device for tuberous root crops, including a first visual detection component 3 and a second visual detection component 17. Both the first visual detection component 3 and the second visual detection component 17 use pulsed LEDs for imaging. The first visual detection surface 2 of the first visual detection component 3 and the second visual detection surface 19 of the second visual detection component 17 are arranged facing each other, forming a feed inlet between the first visual detection surface 2 and the second visual detection surface 19. Below the feed inlet, from top to bottom, are arranged a soil clod sorting component consisting of a soil clod sorting control console 4 and a soil clod diversion plate 15, a defective product sorting component consisting of a defective product sorting control console 5 and a defective product diversion plate 13, and a good product sorting component consisting of a good product sorting control console 6 and a good product diversion plate 11. The soil clod sorting control console 4, the defective product sorting control console 5, and the good product sorting control console 6 are arranged below the first visual detection component 3 from top to bottom. The soil clod diversion plate 11... 5. The defective product guide plate 13 and the good product guide plate 11 are arranged from top to bottom on the lower side of the second vision detection component 17. The good product guide plate 11 is provided with a premium product guide platform 8 on its lower side. Each sorting component's control panel is provided with a lever assembly for pushing materials toward the guide plate on the side closest to the guide plate. Premium products can fall from the feed inlet onto the premium product guide platform 8. The first vision detection component 3 is communicatively connected to the second vision detection component 17, the soil clod sorting control panel 4, the defective product sorting control panel 5, and the good product sorting control panel 6. The first vision component has a control system inside, which receives the images transmitted from the second vision component, combines them with the images it captures, and then controls the soil clod sorting control panel 4, the defective product sorting control panel 5, and the good product sorting control panel 6 to perform sorting actions.

[0023] Furthermore, the first visual detection component 3 and the second visual detection component 17 employ pulsed LED double-sided detection combined with hyperspectral imaging technology and lidar technology to collaboratively acquire and analyze crop features. Hyperspectral imaging can obtain the reflectance information of crops in hundreds of continuous spectral bands, and different crops exhibit significant differences in reflectance across different spectral bands. Legumes, due to the characteristics of their internal chemical components (such as protein and fat content), exhibit specific reflectance spectral curves in the near-infrared spectral region; tuber crops, rich in starch and other substances, have spectral reflectance characteristics significantly different from legumes. The crops are scanned using a hyperspectral imager to acquire hyperspectral image data. Using spectral analysis algorithms, reflectance data of the crops in various spectral bands are extracted, and feature selection is performed to identify the most representative spectral bands for distinguishing crop types, thereby obtaining information on the morphology, structure, defects, and other features of the object's surface.

[0024] Furthermore, a premium product buffer plate 7 is provided on the lower side of the good product sorting control console 6, and a premium product outlet is formed between the premium product buffer plate 7 and the premium product diversion table 8. A soil block buffer plate 16 is provided below the second vision detection component 17, and a soil block outlet is formed between the soil block buffer plate 16 and the soil block diversion plate 15. A defective product buffer plate 14 is provided below the soil block diversion plate 15, and a defective product outlet is formed between the defective product buffer plate 14 and the defective product diversion plate 13. A good product buffer plate 12 is provided below the defective product buffer plate 14, and a good product outlet is formed between the good product buffer plate 12 and the good product diversion plate 11.

[0025] Furthermore, in any sorting assembly, there are multiple sets of lever assemblies, arranged at intervals along the front-back direction. Each lever assembly includes a lever 1 and a motor. The lever 1 and the motor are connected by multiple connecting rods 20. The lever 1 can extend under the drive of the motor and thus lie horizontally between the sorting control console and the deflector plate. The control system controls the motors in all lever assemblies individually.

[0026] Furthermore, each buffer plate has a rubber layer on its surface.

[0027] Furthermore, the end of the flow guide plate closest to its corresponding control panel is higher than the other end, which facilitates material discharge.

[0028] Furthermore, during installation, the upper end of the feed inlet is the discharge end of the feed conveyor belt 18, the lower end of the premium product outlet is the feed end of the premium product conveyor belt 9, and the good product outlet and the defective product outlet are both located on the upper side of the defective and good product conveyor belts 10. Both defective and good products can fall onto the defective and good product conveyor belts 10, and the soil clod diversion plate 15 discharges the soil clods out of the device.

[0029] This embodiment utilizes pulsed LED double-sided detection to acquire information such as object characteristics and volume, thereby achieving comprehensive detection of the object. Based on the quality and damage of tuberous root crops, the material is divided into clods, substandard products, good products, and superior products. Instructions are then issued to each sorting component for sorting, avoiding the drawback of traditional sorting equipment being unable to separate clods, while improving sorting accuracy.

[0030] Each lever 1 operates independently, avoiding the inefficiency of traditional sequential sorting. It can simultaneously detect multiple block-shaped crops, and independently control each lever 1 based on the crop quality information fed back by the vision detection component, thereby improving operational efficiency.
