Description

Technical Field

[0001] This invention relates to the field of grain and oil testing technology, and in particular to a device for detecting impurities in grain and oil quality. Background Technology

[0002] Grains and oils are a collective term for cereals, wheat, beans, oilseeds, and their primary processed products. Grain and oil products are agricultural products that are vital to the national economy and people's livelihoods. They are not only a major source of nutrition and energy for the human body, but also a major raw material for light industry and a major feed for animal husbandry and livestock farming.

[0003] In the processing and quality control of grains and oils, the detection of impurities is a crucial step in assessing grain and oil quality and ensuring food safety. Currently available grain and oil impurity detection devices generally suffer from the following technical deficiencies: 1. Most devices use natural feeding, which makes it easy for grains and oils to accumulate or be unevenly distributed on the detection platform. This makes it impossible for the visual inspection equipment to cover all grain and oil particles, resulting in missed detections. During the detection process, grain and oil particles are mostly in a static state, and only the surface particles can be visually identified. The impurities in the bottom particles cannot be detected, further increasing the missed detection rate. 2. After the test is completed, the impurity removal process requires the grain and oil to be transferred to a separate impurity removal device for processing. This step-by-step operation not only prolongs the overall process time and increases labor and equipment costs, but may also introduce secondary pollution or material loss during the transfer process. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a device for detecting impurities in grain and oil. This device can effectively avoid missed detections caused by grain and oil accumulation, enabling continuous detection of grain and oil, and integrating detection and impurity removal to improve overall efficiency.

[0005] To solve the above problems, the technical solution adopted by the present invention is as follows: A device for detecting impurities in grain and oil includes a detection tank. An annular material plate is rotatably connected inside the detection tank. Visual inspection devices are installed on the upper left and right sides of the annular material plate. A hopper is installed on the upper front and rear sides of the annular material plate. A discharge mechanism and a V-shaped spreading plate are respectively installed on both sides of the hopper along the clockwise rotation direction of the annular material plate. A vibration mechanism is installed below the left and right sides of the annular material plate inside the detection tank. The vibration mechanism includes impact balls that can reciprocate up and down against the annular material plate, causing the grain and oil passing under the visual inspection devices to vibrate and flip. A drive shaft is rotatably connected to the center of the detection tank. Multiple dispersing plates are fixedly installed on the side wall of the drive shaft below the annular material plate. A sieve hopper is fixedly installed below the dispersing plates inside the visual inspection devices. A blowing pipe is provided at the bottom of the dispersing plates.

[0008] Preferably, one end of the V-shaped paving plate is fixedly connected to the inner wall of the testing tank, and the other end is fixedly connected to an annular guard plate. The bottom of the annular guard plate abuts against the annular opening of the annular material plate, and the bottom of the V-shaped paving plate is attached to the annular material plate with a gap of 0.5-1cm.

[0009] Preferably, a servo motor is installed on the top of the testing tank, a drive gear is fixed at the output end of the servo motor, a driven gear that meshes with the drive gear is fixed on the drive shaft, a large gear is also fixedly installed on the drive shaft, a gear ring is fixed on the inner side of the annular material plate, the gear ring and the large gear are driven by a transmission gear, the gear shaft of the transmission gear is rotatably connected to the top of the testing tank, and a support plate is supported in the middle of the gear shaft.

[0010] Preferably, the discharge mechanism includes a baffle plate fixedly connected to the side wall of the annular guard plate. The baffle plate is radially arranged and its bottom abuts against the annular material plate. A transmission box is fixedly installed on the inner side of the annular guard plate. A bevel gear pair is installed in the transmission box. One of the bevel gear pairs is connected to a spiral conveying blade, and the other bevel gear pair is connected to a drive shaft. The end of the drive shaft extends out of the transmission box and is fixed with a pinion. The pinion meshes with a driven gear. The spiral conveying blade is radially arranged on the annular material plate, with its bottom abutting against the annular material plate and one side abutting against the baffle plate.

[0011] Preferably, the side wall of the testing tank is provided with a discharge port corresponding to the end of the spiral conveyor blade, the discharge port is connected to a feeding channel, and the end of the feeding channel corresponds to a dispersing plate.

[0012] Preferably, the vibration mechanism further includes a turntable fixedly mounted on the drive shaft, with a plurality of first magnetic blocks embedded in the circumference of the turntable. Both sides of the inner wall of the detection tank are fixedly mounted with booms, and the ends of the booms are elastically mounted with vibration rods via springs. The upper end of the vibration rod is fixedly connected to an impact ball, and the bottom of the vibration rod is fixed with a second magnetic block that magnetically engages with the first magnetic blocks.

[0013] Preferably, the bottom of the dispersion plate is inclined, the bottom of the air blower is provided with a row of air blow holes, the drive shaft is hollow and connected to multiple air blowers, and the upper end of the drive shaft is connected to an air inlet pipe through a rotary joint.

[0014] Preferably, the bottom of the screen hopper is connected to a discharge pipe, a bracket is fixedly installed inside the discharge pipe, the bottom of the drive shaft is rotatably connected to the bracket, a conical discharge seat is fixedly sleeved on the side wall of the discharge pipe, and the circumferential side wall of the conical discharge seat is provided with multiple discharge ports.

[0015] The beneficial effects of this invention are as follows: 1. By installing a pair of vision inspection devices, a ring-shaped material plate, a pair of V-shaped spreading plates, a pair of discharge mechanisms, and a drive shaft, the motor is started. The drive gear drives the driven gear to rotate, which in turn drives the drive shaft to rotate. Then, the large gear drives the transmission gear to rotate, and finally, the ring-shaped material plate rotates slowly through the gear ring, achieving thorough inspection. Grain and oil in the pair of hoppers continuously fall onto the ring-shaped material plate through the flat material outlet. As the ring-shaped material plate rotates, it reaches the V-shaped spreading plate, spreading the grain and oil concentrated in the middle to both sides, forming a thin layer with a thickness of 0.5-1cm. After focused inspection by the CCD vision inspection system, the captured image can cover the entire surface of the grain and oil, ensuring comprehensive inspection. After inspection, the ring-shaped material plate is continuously discharged through the discharge mechanism, realizing a continuous inspection process with high efficiency.

[0016] 2. By installing a vibration mechanism, the drive shaft synchronously drives the turntable to rotate. The first magnetic block alternately attracts and separates from the second magnetic block as the turntable rotates. Under the elastic force of the spring, the vibration rod drives the impact ball to repeatedly strike the annular material plate, causing the grain and oil particles on the annular material plate to vibrate and turn over. During the process of the first magnetic block attracting the second magnetic block, the annular material plate stops vibrating, which does not affect the shooting process and ensures that all particles can be identified by the visual inspection equipment, further reducing the missed detection rate.

[0017] 3. By installing a discharge mechanism, dispersing plates, a screen hopper, and air blowers, the driven gear synchronously drives a pair of small gears to rotate, which in turn drives the spiral conveyor blades to rotate rapidly through the transmission shaft and bevel gear pair. This continuously discharges the grain and oil collected at the baffle plate and discharges it again to the middle area of ​​the testing tank through the discharge channel. At the same time, the drive shaft drives multiple dispersing plates to rotate. The dispersing plates continuously impact the sliding grain and oil, dispersing it and spreading it throughout the screen hopper. The grain and oil slide down from the top edge of the screen hopper. During the sliding process, the air inlet pipe pumps air into the hollow drive shaft, which then enters multiple air blowers and is finally blown downwards through multiple air holes, blowing impurities away from the screen hopper. The impurities are discharged through the conical discharge seat and multiple discharge ports, while the grain and oil are discharged through the discharge pipe, achieving continuous impurity removal.

[0018] 4. By using a servo motor and gear transmission (drive gear - driven gear, large gear - transmission gear - gear ring, driven gear - small gear), the synchronous operation of the annular material plate, spiral conveyor blade, drive shaft, turntable and dispersing plate is achieved, realizing a continuous detection and impurity removal process, which greatly improves efficiency.

[0021] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Reference Figure 1-7A device for detecting impurities in grain and oil quality includes a detection tank 1. An annular material plate 8 is rotatably connected inside the detection tank 1. Visual inspection devices 4 are installed on the upper left and right sides of the annular material plate 8. The visual inspection devices 4 are CCD visual inspection systems. A detection cover 6 is installed at the bottom of the detection end of the visual inspection device 4. The opening area of ​​the detection cover 6 is the detection area. The opening of the detection cover 6 is close to the annular material plate 8 with a gap of 1-1.5cm, which can focus the detection area, avoid external interference, and accurately identify impurities in grain and oil.

[0023] A hopper 3 is installed on the upper front and rear sides of the annular material plate 8. The hopper 3 is fixedly installed on the top of the testing tank 1, and the bottom of the hopper 3 extends into the tank and connects to a flat material inlet 31. The flat material inlet 31 is radially arranged, and the gap between the bottom of the flat material inlet 31 and the annular material plate 8 is 3-5cm. A discharge mechanism and a V-shaped spreading plate 10 are respectively installed on both sides of the hopper 3 along the clockwise rotation direction of the annular material plate 8. One end of the V-shaped spreading plate 10 is fixedly connected to the inner wall of the testing tank 1, and the other end is fixedly connected to an annular guard plate 9. The bottom of the annular guard plate 9 abuts against the annular opening of the annular material plate 8, and the bottom of the V-shaped spreading plate 10 is attached to the annular material plate 8 with a gap of 0.5-1cm. The grain and oil in the pair of hoppers 3 continuously fall onto the annular material plate 8 through the flat material inlet 31. As the annular material plate 8 rotates, it reaches the V-shaped spreading plate 10, spreading the grain and oil concentrated in the middle to both sides, forming a thin layer of 0.5-1cm thickness, reducing the false detection rate.

[0024] Furthermore, a servo motor 2 is installed on the top of the testing tank 1. A drive gear 22 is fixed to the output end of the servo motor 2. A driven gear 23 that meshes with the drive gear 22 is fixed on the drive shaft 14. A large gear 25 is also fixed on the drive shaft 14. A gear ring 27 is fixed to the inner side of the annular material plate 8. The gear ring 27 and the large gear 25 are driven by a transmission gear 26. The gear shaft 24 of the transmission gear 26 is rotatably connected to the top of the testing tank 1, and a support plate 7 is supported in the middle of the gear shaft 24. When the motor 2 is started, the driven gear 23 is driven to rotate through the drive gear 22, which in turn drives the drive shaft 14 to rotate. Then, the large gear 25 drives the transmission gear 26 to rotate, and finally, the gear ring 27 drives the annular material plate 8 to rotate slowly, thus achieving full testing.

[0025] Vibration mechanisms 15 are installed on both the left and right sides below the annular material plate 8 inside the testing tank 1. The vibration mechanism 15 includes an impact ball 37 that can reciprocate up and down to impact the annular material plate 8, causing the grain and oil particles passing under the visual inspection device 4 to vibrate and turn over. The vibration mechanism 15 also includes a turntable 13 fixedly installed on the drive shaft 14. Multiple first magnetic blocks 35 are embedded in the circumference of the turntable 13. A hanging arm 36 is fixedly installed on both sides of the inner wall of the testing tank 1. The end of the hanging arm 36 is elastically installed with a vibration rod 39 through a spring 40. The upper end of the vibration rod 39 is fixedly connected to the impact ball 37. The bottom of the vibration rod 39 is fixed with a second magnetic block 38 that magnetically attracts and cooperates with the first magnetic blocks 35. The drive shaft 14 synchronously drives the turntable 13 to rotate. The first magnetic blocks 35 alternately attract and separate from the second magnetic blocks 38 as the turntable 13 rotates. Under the elastic force of the spring 40, the vibration rod 39 drives the impact ball 37 to reciprocate up and down to impact the annular material plate 8, causing the grain and oil particles on the annular material plate 8 to vibrate and turn over, further reducing the false detection rate.

[0026] The center of the testing tank 1 is rotatably connected to a drive shaft 14. Multiple dispersing plates 16 are fixedly installed on the side wall of the drive shaft 14 below the annular material plate 8. A sieve hopper 17 is fixedly installed in the visual inspection device 4 below the dispersing plate 16. A blowing pipe 28 is provided at the bottom of the dispersing plate 16. The discharge mechanism sends out the tested grain and oil, which are dispersed by the dispersing plate 16 and then blown away by air to remove impurities.

[0027] Furthermore, the bottom of the dispersing plate 16 is inclined, and the bottom of the blowing pipe 28 is provided with a row of blowing holes 29. The drive shaft 14 is hollow and connected to multiple blowing pipes 28. The upper end of the drive shaft 14 is connected to the air inlet pipe 21 through a rotary joint. The air inlet pipe 21 pumps air into the hollow drive shaft 14, then into the multiple blowing pipes 28, and finally blows it downward through multiple blowing holes 29, blowing the impurities away from the screen hopper 17.

[0028] Specifically, the discharge mechanism includes a baffle plate 11 fixedly connected to the side wall of the annular guard plate 9. The baffle plate 11 is radially arranged and its bottom abuts against the annular material plate 8. A transmission box 34 is fixedly installed on the inner side of the annular guard plate 9. A bevel gear pair 33 is installed in the transmission box 34. One bevel gear pair 33 is connected to the spiral conveying blade 12, and the other bevel gear pair 33 is connected to the drive shaft. The end of the drive shaft extends out of the transmission box 34 and is fixed with a pinion 5. The pinion 5 meshes with the driven gear 23. The spiral conveying blade 12 is radially arranged on the annular material plate 8, with its bottom abutting against the annular material plate 8 and one side abutting against the baffle plate 11. The side wall of the detection tank 1 corresponds to the spiral conveying blade 12. The end of the rotary conveyor blade 12 is provided with a discharge port, which is connected to the discharge channel 32. The end of the discharge channel 32 corresponds to the dispersing plate 16. The driven gear 23 synchronously drives a pair of small gears 5 to rotate, which in turn drives the rotary conveyor blade 12 to rotate rapidly through the transmission shaft and bevel gear pair 33, continuously discharging the grain and oil collected at the baffle plate 11. The grain and oil are then discharged again through the discharge channel 32 to the middle area of ​​the detection tank 1. At the same time, the drive shaft 14 drives multiple dispersing plates 16 to rotate. The dispersing plates 16 continuously impact the sliding grain and oil, dispersing it and spreading it throughout the screen hopper 17, so that the grain and oil slide down from the top edge of the screen hopper 17, thus removing impurities thoroughly.

[0029] The bottom of the sieve 17 is connected to the discharge pipe 18, and a bracket 30 is fixedly installed inside the discharge pipe 18. The bottom of the drive shaft 14 is rotatably connected to the bracket 30. A conical discharge seat 19 is fixedly sleeved on the side wall of the discharge pipe 18. The circumferential side wall of the conical discharge seat 19 is provided with multiple discharge ports 20, which blow impurities away from the sieve 17 and discharge them through the conical discharge seat 19 and multiple discharge ports 20. Grain and oil are discharged through the discharge pipe 18, realizing continuous impurity removal.

[0030] The motor 2 is started, which drives the driven gear 23 to rotate via the drive gear 22, which in turn drives the drive shaft 14 to rotate. The large gear 25 then drives the transmission gear 26 to rotate, and finally the gear ring 27 drives the annular material plate 8 to rotate slowly, achieving full detection. Grain and oil in a pair of hoppers 3 continuously fall onto the annular material plate 8 through the flat material outlet 31. As the annular material plate 8 rotates, it reaches the V-shaped spreading plate 10, spreading the grain and oil concentrated in the middle to both sides, forming a thin layer with a thickness of 0.5-1cm. After focused detection by the CCD vision inspection system, the captured image can cover the entire surface of the grain and oil, ensuring comprehensive detection. After the detection is completed, the annular material plate 8 is continuously discharged through the discharge mechanism, realizing a continuous detection process.

[0031] The drive shaft 14 synchronously drives the turntable 13 to rotate. The first magnetic block 35 rotates with the turntable 13 and alternately attracts and separates from the second magnetic block 38. Under the elastic force of the spring 40, the vibration rod 39 drives the impact ball 37 to repeatedly strike the annular material plate 8, causing the grain and oil particles on the annular material plate 8 to vibrate and turn over. During the process of the first magnetic block 35 attracting the second magnetic block 38, the annular material plate 8 stops vibrating, which does not affect the shooting process and ensures that all particles can be identified by the visual inspection device 4, further reducing the missed detection rate.

[0032] Driven gear 23 synchronously drives a pair of small gears 5 to rotate, which in turn drives the spiral conveyor blades 12 to rotate rapidly through the transmission shaft and bevel gear pair 33, continuously discharging the grain and oil collected at the baffle plate 11. The grain and oil are then discharged again through the discharge channel 32 to the middle area of ​​the detection tank 1. At the same time, drive shaft 14 drives multiple dispersing plates 16 to rotate. The dispersing plates 16 continuously impact the sliding grain and oil, dispersing it and spreading it throughout the screen hopper 17. The grain and oil slide down from the top edge of the screen hopper 17. During the sliding process, air inlet pipe 21 pumps air into the hollow drive shaft 14, which then enters multiple blower pipes 28 and is finally blown downward through multiple blower holes 29, blowing impurities away from the screen hopper 17. The impurities are discharged through the conical discharge seat 19 and multiple discharge ports 20, and the grain and oil are discharged through the discharge pipe 18, achieving continuous impurity removal.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
