Description

Technical Field

[0001] This invention relates to a high-precision intelligent oil sorting device. Background Technology

[0002] Oilseeds and other oilseed particles have the physical characteristics of small particle size, smooth surface, and strong rolling properties. In the sorting process of existing oilseed color sorting equipment, there are common problems such as uneven feeding, material clumping and rolling, and overlapping of particles. Traditional color sorting equipment mostly adopts a fixed flat belt feeding structure, which cannot adapt to the strong rolling characteristics of oilseeds. It is very easy for oilseeds to roll off in batches and accumulate into clumps. Clumps of oilseed particles will block the field of view of the color sorter's CCD lens, making it impossible for the lens to clearly and accurately capture the appearance image of individual oilseed particles.

[0003] Meanwhile, traditional equipment has poor precision in adjusting the feeding speed and a simple and single material diversion structure, which makes it impossible to achieve single-particle dispersion of oil particles. This makes it impossible for the color sorter processor to accurately determine the location of bad materials, and causes deviations in the spray valve's impurity removal action. Ultimately, this results in problems such as low oil color sorting accuracy, incomplete removal of bad materials, and high loss rate of good products, which cannot meet the high-precision sorting production requirements for high-quality oil processing.

[0004] Based on the above problems, there is an urgent need for a high-precision intelligent oil sorting device that can achieve uniform distribution of oil, allow color sorters to accurately capture images, improve screening accuracy, and reduce the number of repeated color sorting operations. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a high-precision intelligent oil sorting device that can achieve uniform distribution of oil, enable color sorters to accurately capture images, improve screening accuracy, and reduce the number of repeated color sorting operations.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A high-precision intelligent oil sorting device includes,

[0008] The frame body has its lower end fixed to the ground, and its upper part is provided with a first platform and a second platform, with the height of the first platform being higher than that of the second platform.

[0009] A feeding device is installed on a first platform. Ground-loaded materials are injected into the feeding device, and the feeding speed is adjusted by the feeding device.

[0010] A chute device is installed at the discharge position of the feeding device, and the chute device is responsible for diverting the oil.

[0011] A color sorter is fixedly installed on the top of the second platform, and the oil that slides down through the chute device falls into the color sorter.

[0012] The material distribution hopper is installed at the discharge position of the color sorter. The bottom of the material distribution hopper is provided with a first discharge port and a second discharge port. The second discharge port corresponds to the discharge direction of the chute device, and the first discharge port is deviated from the discharge direction of the chute device.

[0013] The spray valve device includes multiple spray valves connected in parallel. The spray valve device is connected to the color sorter and is responsible for spraying the defective materials that have been photographed and identified into the first discharge port through high-pressure airflow.

[0014] Preferably, the feeding device includes a cover plate, a movable trough, a conveyor, a storage hopper, and servo push rods. A mounting hole is provided on the top of the cover plate near the left side. A tube is provided at the bottom axis of the storage hopper, inserted through the mounting hole and fixed to the cover plate. Two or more crossbars are fixed to the top of the cover plate and are fixed to the frame. Multiple servo push rods are provided, arranged front and rear on both sides of the cover plate. The movable trough is located below the cover plate. The movable ends of the multiple servo push rods are fixed to the movable trough. The multiple servo push rods are synchronously controlled by a servo system to raise or lower the height of the movable trough. The conveyor is installed through the movable trough. When the movable trough is raised to its limit position by the servo push rods, the conveyor closes the lower opening of the tube, stopping the feeding. The left end of the movable trough is closed. The chute device is fixedly installed on the right end of the movable trough.

[0015] Preferably, a receiving trough is fixedly provided at the bottom of the movable trough, and the height of the receiving trough gradually decreases in the direction away from the chute device. The oil leaking from the conveyor is received through the receiving trough, and a discharge pipe is provided on the left side of the receiving trough.

[0016] Preferably, the conveyor includes drive rollers, tension rollers, a conveyor belt, and a drive motor. Multiple drive rollers are horizontally arranged and rotatably engage with a movable groove via bearings. The tension rollers are rotatably engaged with the movable groove via bearings and are arranged parallel to the drive rollers below them. The conveyor belt is installed between the multiple drive pipes and the tension rollers. The drive motor is fixed to the outside of the movable groove and inserted into and fixed to the drive roller at its end. When the movable groove descends, the distance between the upper surface of the conveyor belt and the inserted pipe increases, thus increasing the material feed rate. When the movable groove reaches its limit position, the conveyor belt closes the inserted pipe, and material feed stops.

[0017] Preferably, the outer surface of the conveyor belt is provided with a groove, and baffles are evenly distributed at the bottom of the groove. A storage trough is formed between adjacent baffles. The baffles are inclined in the conveying direction of the conveyor belt, and their upper edges are lower than the surface of the conveyor belt. A rubber ring is clamped at the bottom opening of the insertion tube. When the conveyor belt moves upward with the movable groove to the limit position, the rubber ring connects with the baffle, so that the oil stops feeding after filling part of the storage trough.

[0018] Preferably, the baffle plate has a disconnection groove on both sides, the width of the disconnection groove is smaller than the particle size of the oil, and the depth of the disconnection groove is less than 1 / 2 of the width of the baffle plate.

[0019] Preferably, the front and rear sides of the cover plate are bent downward to form side baffles, and the bottom of the side baffles is provided with a U-shaped groove to accommodate the central shaft of the transmission roller.

[0020] Preferably, the chute device includes a side cover and a chute plate. The side cover is fixed to the right end of the movable chute. An opening groove is provided on the upper part of the side cover. A portion of the conveyor belt is located in the opening groove. A discharge port is provided at the bottom of the side cover. The chute plate is fixed to the bottom of the side cover so that the oil falling from the discharge port falls onto the chute plate. The end of the chute plate is inserted into the feeding position of the color sorter. Multiple parallel chutes are provided on the surface of the chute plate.

[0021] Preferably, the upper end of the chute is provided with a V-shaped guide groove, and the lower end face of the side cover is in contact with the inner bottom surface of the chute plate. At this time, the guide groove is located inside the side cover, so that the oil falling through the discharge port is received by the guide groove and distributed to the chute.

[0022] Preferably, a groove is provided on the top of the side cover, through which a slide plate can be slidably installed up and down. The upper end of the slide plate is bent vertically to the right. A first servo push rod is fixed on the right side of the side cover. The telescopic end of the first servo push rod is fixedly connected to the slide plate. Dispersing rods are evenly distributed on the side of the slide plate facing the movable groove. The oil falling from the conveyor belt is dispersed by the dispersing rods. The distance between adjacent dispersing rods is greater than the particle size of the oil.

[0023] The beneficial effects of this invention are:

[0024] 1. This invention optimizes the structure of the feeding device by setting grooves, baffles, and storage troughs on the surface of the conveyor belt, which completely solves the problem of strong rolling and easy rolling of oilseed particles such as rapeseed. The oilseeds can be evenly stored in the storage trough, achieving uniform lateral distribution. At the same time, the height of the conveyor belt can be precisely adjusted by servo push rods, achieving precise control of the feeding speed within the range of 0~10mm. When the machine stops, the insertion pipe can be completely sealed to prevent leakage and residual material discharge.

[0025] 2. The chute device of the present invention is equipped with multiple independent chutes, combined with a V-shaped guide chute and a sliding dispersion rod structure, which can further disperse and divert the falling oil, so that the oil particles fall into the color sorter one by one and evenly, completely avoiding the situation of material clumping and stacking and blocking the CCD lens, ensuring that the lens can clearly capture the image information of each oil particle, and greatly improving the color sorting recognition accuracy.

[0026] 3. The disconnecting grooves on both sides of the baffle plate can effectively compensate for fitting errors during equipment assembly and operation, providing space for the baffle plate to deform elastically. At the same time, when pressing down to insert the tube, the elastic deformation of the baffle plate can also improve the sealing performance of the rubber ring. In addition, the design of the disconnecting groove width being smaller than the oil particle size can prevent oil leakage, thus balancing equipment operation stability and material utilization rate.

[0027] 4. The overall structure of the equipment is highly interconnected. Through multi-level optimization of precise material feeding control, uniform diversion in the middle, and single-piece material dropping at the end, combined with mature color sorting and spray valve impurity removal structure, the good product loss rate of oil sorting is greatly reduced, the accuracy of defective material rejection is improved, and it is suitable for the needs of large-scale and high-precision processing and production of high-quality oil.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0053] See Figure 1 The high-precision intelligent oil sorting device shown includes,

[0054] The frame body 1 has its lower end fixed to the ground, and a first platform 11 and a second platform 12 are provided on the upper part of the frame body 1. The height of the first platform 11 is higher than that of the second platform 12.

[0055] The feeding device 2 is installed on the first platform 11. Ground-loaded materials are injected into the feeding device 2, and the feeding speed is adjusted by the feeding device 2.

[0056] The chute device 3 is installed at the discharge position of the feeding device 2 and is responsible for diverting the oil.

[0057] Color sorter 4 is fixedly installed on the top of the second platform 12, and the oil that slides down through the chute device 3 falls into the color sorter 4.

[0058] The material distribution hopper 5 is installed at the discharge position of the color sorter 4. The bottom of the material distribution hopper 5 is provided with a first discharge port 51 and a second discharge port 52. The second discharge port 52 corresponds to the discharge direction of the chute device 3, and the first discharge port 51 is deviated from the discharge direction of the chute device 3.

[0059] The spray valve device 6 includes multiple spray valves connected in parallel. The spray valve device 6 is connected to the color sorter 4 and is responsible for spraying the defective materials that have been photographed and identified into the first discharge port 51 through high-pressure airflow.

[0060] In the above technical solution, a mature color sorter 4 is used. The color sorter 4 is equipped with a light source and at least two CCD lenses. The light source illuminates the sample, and the CCD lenses take pictures and transmit the pictures to the processor. The processor determines the location of the bad material to be removed and then opens the spray valve at that location at a timed interval. After the solenoid valve of the spray valve opens, a high-speed airflow is sprayed out, blowing the bad particles to the first discharge port 51, thus completing the separation of good and bad oil materials.

[0061] Compared with traditional color sorting equipment, the advantage of this technical solution is that the material is evenly distributed from the moment it enters the color sorter 4 through the specially designed feeding device 2 and chute device 3, so that the oil is evenly dispersed when it enters the color sorter 4, avoiding clumping and blocking the CCD lens after passing through, thus improving the screening accuracy.

[0062] See Figure 2 and Figure 3 As shown, the feeding device 2 includes a cover plate 21, a movable trough 22, a conveyor 23, a storage hopper 24, and servo push rods 25. A mounting hole is provided on the top of the cover plate 21 near the left side. A tube 241 is provided at the bottom axis of the storage hopper 24, inserted through the mounting hole and fixed to the cover plate 21. Two or more crossbars 210 are fixed to the top of the cover plate 21 and are fixed to the frame body 1. Multiple servo push rods 25 are provided, arranged front and rear on both sides of the cover plate 21. The movable groove 22 is located below the cover plate 21. The movable ends of the plurality of servo push rods 25 are fixed to the movable groove 22. The plurality of servo push rods 25 are synchronously controlled by a servo system to raise or lower the height of the movable groove 22. The conveyor 23 is installed through the movable groove 22. When the movable groove 22 is raised to the limit position by the servo push rods 25, the conveyor 23 closes the lower opening of the insertion tube 241, and the material discharge stops. The left end of the movable groove 22 is closed. The chute device 3 is fixedly installed at the right end of the movable groove 22.

[0063] In the above technical solution, the feeding speed of the oil is adjusted by changing the height of the conveyor 23, and the height adjustment range of the conveyor 23 is between 0 and 10 mm.

[0064] The greater the distance between the conveyor 23 and the insertion tube 241, the faster the material feeding speed.

[0065] When the conveyor 23 stops and rises to its limit position, the insertion pipe 241 can be blocked to prevent material discharge.

[0066] See Figure 2As shown, a receiving trough 221 is fixedly provided at the bottom of the movable trough 22. The height of the receiving trough 221 gradually decreases in the direction away from the sliding chute device 3. The oil leaking from the conveyor 23 is received through the receiving trough 221. A discharge pipe 222 is provided on the left side of the receiving trough 221.

[0067] Oilseeds (the oilseeds in this case are rapeseed) have a strong rolling ability, and some oilseeds will inevitably roll into the movable trough 22. This part of the leaked material can be received by the receiving trough 221 and discharged through the discharge pipe 222.

[0068] See Figure 2 and Figure 4 As shown, the conveyor 23 includes a drive roller 231, a tension roller 232, a conveyor belt 233, and a drive motor 234. Multiple drive rollers 231 are horizontally arranged and rotatably engage with a movable groove 22 via bearings. The tension rollers 232 are rotatably engaged with the movable groove 22 via bearings and are arranged parallel to the drive rollers 231 below them. The conveyor belt 233 is installed between the multiple drive rollers 231 and the tension rollers 232. The drive motor 234 is fixed to the outside of the movable groove 22 and is inserted and fixed to the drive rollers 231 at its end. When the movable groove 22 descends, the distance between the upper surface of the conveyor belt 233 and the insertion tube 241 increases, thus increasing the material feed rate. When the movable groove 22 reaches its limit position, the conveyor belt 233 closes the insertion tube 241, stopping the material feed.

[0069] See Figure 4 and Figure 5 As shown, the outer surface of the conveyor belt 233 is provided with a groove 2330, and baffles 2331 are evenly distributed at the bottom of the groove 2330. A storage trough 2332 is formed between adjacent baffles 2331. The baffles 2331 are inclined towards the conveying direction of the conveyor belt 233, and their upper edges are lower than the belt surface of the conveyor belt 233. A rubber ring 2410 is clamped at the bottom opening of the insertion tube 241. When the conveyor belt 233 moves upward with the movable groove 22 to the limit position, the rubber ring 2410 connects with the baffles 2331, so that the oil stops feeding after filling part of the storage trough 2332.

[0070] Considering the rolling nature of oil, this technical solution creatively sets a groove 2330 on the outside of the conveyor belt 233, and is equipped with evenly distributed baffles 2331, so that the oil falling from the insertion tube 241 is effectively stored in the storage trough 2332, which avoids the problem of oil rolling off compared with the traditional flat belt.

[0071] Secondly, the baffle plate 2331 is inclined towards the conveying direction of the conveyor belt 233, so when the conveyor belt runs to the right side of the movable trough 22, the storage trough 2332 gradually pours out the oil inside by tilting downwards.

[0072] Secondly, the oil particles have strong rolling properties, and the storage groove 2332 formed by the baffle plate 2331 can make the oil particles evenly distributed laterally, making the subsequent material drop more uniform.

[0073] See Figure 4 , Figure 5 and Figure 6 As shown, the baffle plate 2331 has a disconnection groove 2333 on both sides. The width of the disconnection groove 2333 is smaller than the particle size of the oil, and the depth of the disconnection groove 2333 is less than 1 / 2 of the width of the baffle plate 2331.

[0074] Considering the fit error, even if the conveyor belt 233 rises to the top of the baffle 2331 and exceeds the lower edge of the rubber ring 2410, the upper part of the baffle 2331 can still have space for elastic deformation by disconnecting the groove 2333.

[0075] The width of the disconnect groove 2333 is smaller than the particle size of the oil to prevent the oil from rolling out from the disconnect groove 2333.

[0076] See Figure 13 As shown, the setting of the disconnect groove 2333 makes the upper part of the baffle plate 2331 more flexible and flexible. When the material is closed, the insertion tube 241 drops in height and is pressed between multiple baffle plates 2331 by the rubber ring 2410. The combination of the baffle plates 2331 seals the lower part of the rubber ring 2410, thereby reducing the amount of material leakage when the rubber ring 2410 is closed.

[0077] See Figure 2 , Figure 7 and Figure 8 As shown, the front and rear sides of the cover plate 21 are bent downward to form side baffles 211, and the bottom of the side baffles 211 is provided with a U-shaped groove 212 that accommodates the central axis of the transmission roller 231.

[0078] The side baffle 211 is designed to reduce the chance of oil spillage and to keep the oil completely stored inside the movable trough 22.

[0079] See Figure 9 , Figure 10 and Figure 11 As shown, the chute device 3 includes a side cover 31 and a chute plate 32. The side cover 31 is fixed to the right end of the movable groove 22. An opening groove 310 is provided on the upper part of the side cover 31. A portion of the conveyor belt 233 is located in the opening groove 310. A discharge port is provided at the bottom of the side cover 32. The chute plate 32 is fixed to the bottom of the side cover 32, so that the oil falling from the discharge port falls onto the chute plate 32. The end of the chute plate 32 is inserted into the feeding position of the color sorter 4. Multiple parallel chutes 321 are provided on the surface of the chute plate 32.

[0080] In the above technical solution, the width of the chute 321 is slightly larger than the particle size of the oil being sorted, with the diameter of conventional oil as a reference value.

[0081] This ensures that the oil particles in the chute 321 fall off one by one, facilitating accurate identification by the color sorter 4 and avoiding the problem of overlapping oil particles falling off.

[0082] See Figure 11 As shown, the upper end of the chute 321 is provided with a V-shaped guide groove 322, and the lower end face of the side cover 31 is in contact with the inner bottom surface of the chute plate 32. At this time, the guide groove 322 is located inside the side cover 31, so that the oil falling through the discharge port is received by the guide groove 322 and distributed to the chute 321.

[0083] The guide chute 322 is designed to allow oil particles to smoothly enter the chute 321.

[0084] Secondly, the lower end face of the side cover 31 contacts the inner bottom surface of the slide plate 32, so that the particles entering the guide groove 322 can only roll down through the slide 321.

[0085] See Figure 9 , Figure 10 and Figure 12 As shown, a groove is provided on the top of the side cover 31, through which a slide plate 33 can be slidably installed. The upper end of the slide plate 33 is bent vertically to the right. A first servo push rod 34 is fixed on the right side of the side cover 31. The telescopic end of the first servo push rod 34 is fixedly connected to the slide plate 33. Dispersing rods 35 are evenly distributed on the side of the slide plate 33 facing the movable groove 22. The oil falling from the conveyor belt 233 is dispersed by the dispersing rods 35. The distance between adjacent dispersing rods 35 is greater than the particle size of the oil.

[0086] In the above technical solution, the oil particles conveyed from the upper surface of the conveyor belt 233 are dispersed by the dispersing rod 35 when they fall through the intermittent up and down sliding of the slide plate 33, and pass through the gap of the dispersing rod 35.

[0087] Furthermore, the horizontal distribution of the storage tank 2332 allows for a more even distribution of the oil.

[0088] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
