Description

Technical Field

[0001] This utility model relates to the field of shelling machine technology, and in particular to an intelligent pea shelling machine. Background Technology

[0002] With the continuous development of agricultural mechanization, pea shelling has become an important production link. Traditional pea shelling methods are inefficient, labor-intensive, and prone to pea damage and waste. Therefore, developing an intelligent pea shelling machine to improve shelling efficiency and reduce labor intensity has important practical significance and theoretical value. Through research and analysis of existing pea shelling machines, the following problems were found: low shelling efficiency, high labor intensity, and complex operation. (1) In terms of shelling efficiency, due to imperfect technology, the machine may not be able to process a large number of peas quickly, resulting in a slow overall shelling speed, which is difficult to meet the needs of large-scale production. (2) Technological defects may lead to incomplete shelling of peas, with some shells remaining, or damage to the seeds inside the peas during the shelling process, affecting the quality of the peas. (3) In terms of adapting to different varieties and sizes of peas, insufficient technology may lead to poor machine flexibility. Different varieties of peas have different shell hardness, shape, etc., and existing intelligent pea shelling machines may not be able to adapt well to these differences and cannot perform precise shelling operations for different peas.

[0003] While existing research has proposed some improvement solutions to address these issues, the results have not been ideal. This application aims to solve the problems in the existing technology and improve the performance of pea hulling machines through intelligent technology. Utility Model Content

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] This utility model provides a technical solution: an intelligent pea shelling machine, such as... Figure 1-4 As shown, it includes a frame 1, a hopper 4, a drum 6, a spiral roller 5, a motor 11, a transmission roller, a conveyor belt 9, a fan 14, a camera 13, an air gun 12, and a detachable collection bin 3.

[0030] The hopper 4 is fixed to the top of the frame 1. The lower part of the hopper 4 is provided with a narrow inlet. The roller 6 is fixed to the middle of the frame 11 by screws. The spiral roller shaft 5 is horizontally set inside the roller 6 and connected to the inner wall of the roller 6 by metal screws. The motor 11 drives the spiral roller shaft 5 and the fan 14 to rotate through the transmission roller and the conveyor belt 9 respectively.

[0031] The spiral roller 5 is a hollow structure made of 4A01 aluminum alloy. 4A01 aluminum alloy has good oxidation resistance and corrosion resistance, making it suitable for handling materials with corrosive substances and able to handle the acidic components in pea juice. Furthermore, 4A01 aluminum alloy has a low density, which makes it lighter for the same volume.

[0032] Its surface has multiple keyed grooves; a shelling gap is formed between the inner wall of the roller 6 and the spiral roller shaft 5 for crushing peas. The spiral roller shaft 5 is 1200mm long and φ420mm in diameter. The spiral roller shaft 55 is made of hollow aluminum alloy. According to research, the density of aluminum alloy 4A01 is 2.63~2.85g / cm³. 3 Between these values, the average value ρ = 2700 kg / m³ is taken. 3 The working roller is designed to be hollow, with a weight of m = 20kg. The spiral roller 55 has 36 keyways and 8 grooves, each 18mm wide. This design allows the beans to fall intact without excessively damaging the bean skins, thus enabling better collection and cleaning of damaged bean skins.

[0033] The transmission roller includes a first pulley 7 and a second pulley 10. The output end of the motor 11 is provided with the second pulley 10. The second pulley 10 is connected to the bearing 15 through the conveyor belt 9. The fan 14 is mounted on the bearing 15 and is driven to rotate by the motor 11.

[0034] The fan 14 is located below the roller 66. The fan 14 uses five curved blades and its airflow direction is perpendicular to the outlet of the roller 6. An arc-shaped filter screen 18 is provided below the roller 6. The aperture of the arc-shaped filter screen 18 is larger than the pea kernel and smaller than the pea skin. Baffles 17 are provided at the ends of the arc-shaped filter screen 18. The two baffles 17 are at a 45° angle to the horizontal plane.

[0035] One end of the spiral roller shaft 5 is provided with a first pulley 7, which is connected to a second pulley 10 via a conveyor belt 9 and is driven to rotate by a motor 11.

[0036] The camera 13 and the air gun 12 are mounted below the curved filter 18. The camera 13 is connected to the air gun 12 via a Raspberry Pi. The air gun 12 has multiple independent air holes, and the positions of the air holes are aligned with the detection area of ​​the camera 13 for sorting bad beans.

[0037] A funnel device 19 is provided below the filter screen 18 and above the camera 13. Several circular holes are opened at the bottom of the funnel device 19. The independent air holes of the air gun 12 correspond one-to-one with the circular holes opened at the bottom of the funnel device 19. The diameter of the holes matches the size of the peas and is used to adjust the vertical falling path of the peas.

[0038] The intelligent pea shelling machine requires a roller, a fan 14, an air gun 12, a camera 13, and a Raspberry Pi to perform dynamic operations. The roller and fan 14 are connected to the motor 11 via a transmission belt and a conveyor wheel, and obtain kinetic energy from the motor 11.

[0039] The filtration device consists of an arc-shaped filter screen 18, a fan 14, and a baffle 17. After the beans are shelled, they fall onto the filter screen and fall through the holes. The bean skins are blown into the air by the fan 14 and onto the collecting baffle 17, thus completing the filtration after shelling.

[0040] This device uses five-bladed curved fan blades to improve airflow and reduce noise, resulting in smoother airflow. Air is blown more evenly, requiring less rotation speed and producing lower noise.

[0041] The curved filter screen 18 uses a curved, round-hole screen and is installed below the roller 6. Exposed peas and damaged pea skins fall onto the filter screen. Because the curved filter screen 18 is curved, the peas will roll to the lowest hole due to their own gravity, preventing peas from piling up or getting stuck. The holes are designed to be round, allowing the peas to fall through. Damaged pea skins are too large compared to the holes in the filter screen, so they are caught by the screen and then blown away by the air blown by the fan 14, thus completing the filtration process.

[0042] The baffle 17 is positioned opposite the pea outlet at a 45° angle to the horizontal plane. Its purpose is to collect pea debris and prevent pea skin debris from falling to other locations, thus avoiding difficulties in collecting pea skins.

[0043] The detection device consists of a row of air guns 12, a row of cameras 13, and a small Raspberry Pi computer. The air guns 12 and cameras 13 are mounted below the curved filter 18 and above the collection plate, with their overall position on the side of the pea sheller, in the center of the pea sheller.

[0044] A funnel is added above camera 13, with 10 holes at the bottom corresponding to the size of peas. The peas fall through these holes, which helps to adjust the direction of the peas' fall, allowing them to fall vertically. This reduces the calculation of peas being blown away by the air gun, making it more convenient for camera 13 to detect peas and for the air gun to work. The peas are detected intact and in a regular pattern by camera 13, and then the 10 air guns blow away any bad peas.

[0045] The detachable collection chamber 3 is fixed to the frame 1 by a snap-fit ​​structure and is located directly below the funnel device 19.

[0046] The jet gun 12 is mounted on the air gun bracket 16.

[0047] The working principle of this invention is as follows: Pea pods first enter the shelling area through the feed inlet under gravity. After entering the hopper 4, the pods fall as a thin layer through the narrow feed opening at the bottom into the roller 6, where they collide and rub against the roller shaft. Under the impact and friction of the roller shaft, the pea shells break, thus achieving shelling. The spiral roller shaft contacts the container wall to crush and squeeze the peas to remove the shells. As they fall, they are subjected to the regulated airflow from the fan 14. The pea skins, being lighter, are carried by the airflow into the collection device, while the pea kernels, being heavier, continue to fall, thus achieving the purpose of separating the shells and kernels. The beans, under gravity, pass through the filter holes of the filter screen and fall into the detection device. In mid-air, they enter the detection range of the camera 13. The image captured by the camera 13 is fed back to the main program, which judges the quality of the beans. Good beans continue to fall to the collection device, while bad beans are blown by the air gun to another collection device, completing the classification of the beans.

[0048] The main method of mechanical connection is through different types of metal screws.

[0049] 1. Improve the stability and reliability of connectors: When screws are used to fix two parts together, their thread characteristics can form a fixed mechanical structure, preventing relative movement and loosening of the connectors during operation, thereby ensuring the stability and reliability of the connectors.

[0050] 2. Reduced workload: Screw fixing is simpler and faster than traditional connection methods such as welding and riveting. It requires more basic tools and equipment, and the operation process is relatively simple, which can greatly reduce the workload and reduce production costs.

[0051] 3. Easy to maintain and replace: Screw-fixed connections are easy to disassemble, maintain and replace. For equipment and machines that require repair or replacement of parts, using screws can save a lot of time and costs.

[0052] The motor 11 used in this application is a Siemens 1LE0001; the camera 13 is a Logitech C270 scanning camera 13.

[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
