Description
Technical Field
[0001] The utility model belongs to the technical field of seed detection, and particularly relates to a rapid detection device for internal cracks of transmissive corn seeds. Background Art
[0002] Seeds are the most basic production materials for crop production and are the key to agricultural production. The quality of seeds directly affects the yield and quality of crops. Corn is one of the most important food crops in China. Controlling the quality inspection of corn seeds is of great significance for ensuring the later planting and harvesting of corn. With the continuous improvement of the degree of agricultural mechanization, agricultural production mostly adopts mechanized operations, but mechanized operations usually cause damage to agricultural products. During the processes of harvesting, drying, and mechanical threshing of corn seeds, they are inevitably mechanically damaged. Especially for corn with a high moisture content that is harvested in the field or not fully dried after harvesting, the probability of mechanical damage is relatively high. A main form of mechanical damage is that seeds have cracks. Cracked seeds are prone to breakage during transportation, are prone to absorb moisture, mildew, and produce pests and diseases during storage, and are also not conducive to the storage of nutrients, ultimately resulting in a decrease in the germination rate of seeds. Therefore, to ensure the quality of seeds, it is necessary to detect whether the seeds have cracks. The utility model provides a rapid detection device for internal cracks of transmissive corn seeds to quickly detect the internal conditions of seeds. Summary of the Invention

Detailed implementation manner
[0016] In order to make the purpose, technical solutions and beneficial effects of the present utility model clearer, the following will combine the accompanying drawings to detail the preferred embodiments of the present utility model for the convenience of those skilled in the art to understand.
[0017] As Figures 1-3 , the present utility model discloses a rapid detection device for internal cracks of transmissive corn seeds. The rapid detection device for internal cracks of transmissive corn seeds includes a detection box 1, a camera 2, a light source 3, a blanking mechanism 4, an infrared sensor 5, a vibration motor 6 and a computer 7. A detection cover 8 is installed on the detection box 1. The camera 2 is installed in the detection cover 8. The light source 3 is installed in the detection box 1 and is located below the camera 2. A conveyor belt 9 is also provided in the detection box 1, and the conveyor belt 9 passes through the space between the camera 2 and the light source 3. One end of the detection box 1 is provided with a blanking port 10. The blanking mechanism 4 is installed on one side of the blanking port 10. The infrared sensor 5 is installed on the blanking port 10. The vibration motor 6 is installed on the blanking mechanism 4. The computer 7 is installed on the detection box 1. The camera 2, the light source 3, the infrared sensor 5 and the vibration motor 6 are all electrically connected to the computer 7; it can realize the rapid detection of internal cracks of corn seeds. The infrared sensor can detect whether the seeds are normally blanked and whether they are blocked during the blanking process. If blocked, the blanking mechanism can be vibrated by the vibration motor to avoid seed blockage. During the detection process, the flow of seeds can be restricted to avoid too many seeds falling onto the conveyor belt or stacking at one time, thus avoiding affecting the detection effect.
[0018] The described blanking mechanism 4 includes a blanking cylinder 11, a material guiding plate 12, a flow limiting plate 13, a first support column 14 and a second support column 15. On the left and right sides of one end of the detection box 1, a first support column 14 is installed. The blanking cylinder 11 is installed on the first support column 14. On the left and right sides of one end of the detection box 1 and in front of the first support column 14, a second support column 15 is provided. The material guiding plate 12 is inclined and installed on the second support column 15. One end of the material guiding plate 12 is located below the blanking cylinder 11, and the other end is located on the blanking port 10. The width of the material guiding plate 12 gradually becomes narrower from top to bottom. A connecting rod 16 is also provided between the material guiding plate 12 and the first support column 14. The vibration motor 6 is installed at the bottom of the material guiding plate 12. During detection, corn seeds are poured into the blanking cylinder and then fall onto the material guiding plate. The material guiding plate includes a bottom plate and baffles around the bottom plate. The width of the material guiding plate gradually becomes narrower from top to bottom, which can limit the flow of the jade, avoiding too many seeds falling onto the conveyor belt at one time and affecting the detection effect.
[0019] The described infrared sensor 5 includes an infrared emitter 17 and an infrared receiver 18. The infrared emitter 17 and the infrared receiver 18 are respectively installed inside the left and right sides of the detection box 1, and the infrared emitter 17 and the infrared receiver 18 are located between the conveyor belt 9 and the other end of the material guiding plate 12. The infrared emitter 17 and the infrared receiver 18 are electrically connected to the computer 7. The infrared emitter and the infrared receiver can detect whether the seeds normally fall from the material guiding plate onto the conveyor belt. If the seeds are not detected falling for a long time, the material guiding plate can be vibrated by the vibration motor to avoid seed blockage and affect the detection efficiency.
[0020] The flow limiting plate 13 is inclined and installed on the material guiding plate 12, and a gradually narrowing blanking cavity is formed between the flow limiting plate 13 and the material guiding plate 12 from top to bottom; it can further limit the flow of seeds, avoiding too many seeds falling at one time and affecting the detection effect.
[0021] At the bottom of the other end of the detection box 1, there is a discharge port 19; the detected seeds can fall from the discharge port, and a box can be used to catch the seeds below the discharge port.
[0022] At the bottom of the detection box 1, there is a support frame 20; it can support the device.
[0023] Working process:
[0024] The working principle of the present utility model is as follows: during detection, corn seeds are poured into the blanking cylinder 11 and then fall onto the material guiding plate 12. The material guiding plate 12 includes a bottom plate and baffles around the bottom plate. The width of the material guiding plate 12 gradually narrows from top to bottom. A gradually narrowing blanking cavity is formed between the current limiting plate 13 and the material guiding plate 12 from top to bottom. The material guiding plate 12 and the current limiting plate 13 can restrict the flow of the corn, preventing too many seeds from falling onto the conveyor belt 9 at one time and stacking up, which may affect the detection effect. The seeds are conveyed to the lower part of the camera 2 through the conveyor belt 9. The light source 3 below the conveyor belt 9 is turned on to irradiate the seeds. The camera 2 can collect the transmission images of the seeds. The computer 7 can identify the collected photos to detect the crack rate of the seeds. The infrared emitter 17 and the infrared receiver 18 can detect whether the seeds normally fall from the material guiding plate 12 onto the conveyor belt 9. If no seeds are detected falling for a long time, the material guiding plate 12 can be vibrated by the vibration motor 6 to prevent seed blockage and affect the detection efficiency.
