Technical Field
[0001] This utility model relates to the field of grain testing technology, and in particular to a novel double-sided grain imperfection analyzer. Background Technology
[0002] Grain has been a staple food for people since ancient times. Both the south and the north cultivate a great deal of grain every year, and various regions also store grain. However, due to the differences in climate between the north and the south, there are also great differences in grain quality. Furthermore, analysis shows that grain quality also affects its storage and is beneficial to manufacturers that use grain as raw material to produce various products.
[0003] Traditional grain quality testing mainly relies on manual sampling and selection. This not only requires a complicated process, but also consumes a lot of manpower, material resources, and space. In addition, the selection of grain requires constant human observation, which is a great challenge to the eyes in the long run. Another testing method is to use equipment for selection. However, the number of grain imperfection analysis devices available on the market is not only small, but their designs are also too complicated. The grain testing process has many steps, and the steps cannot be connected in an orderly manner, which makes the testing cycle too long and affects the testing efficiency.
[0004] Therefore, it is necessary to develop a new grain testing device to achieve the goal of orderly and efficient testing. Utility Model Content

[0027] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0028] Example: Figure 1 and 2 As shown, the novel double-sided grain imperfection analyzer of this embodiment includes a chassis 1 and a material storage and discharging assembly 2, a transparent grain carrier plate 3, a first translation assembly, a material leveling and scraping assembly 4, a second translation assembly, two sets of cameras 5, and a material collection and weighing assembly 6, all respectively disposed in the chassis 1. The material storage and discharging assembly 2 is disposed on the upper left side inside the chassis 1. The grain carrier plate 3 is horizontally disposed below the material storage and discharging assembly 2. The first translation assembly is connected to the grain carrier plate 3 and is used to drive the grain carrier plate 3 to translate left and right. The material leveling and scraping assembly 4 is disposed in the upper left side inside the chassis 1. The material feeding and unloading component 2 is located on the right side and above the grain carrier plate 3. The second translation component is connected to the material leveling and scraping component 4 and is used to drive the material leveling and scraping component 4 to move left and right. The material collection and weighing component 6 is located on the lower right side of the machine box 1. The two sets of cameras 5 are respectively located above and below the grain carrier plate 3 and are respectively connected to the machine vision system. The top of the machine box 1 is provided with an inlet (c in the figure) corresponding to the position of the material storage and unloading component 2. The side wall of the machine box 1 is provided with an outlet (d in the figure) corresponding to the position of the material collection and weighing component 6.
[0029] The usage process is as follows:
[0030] Grain is fed into the storage and unloading assembly 2 through the feed inlet at the top of the chassis 1. When testing is required, the grain carrier plate 3 is moved horizontally by the first translation component to a position below the unloading inlet of the storage and unloading assembly 2 (ideally, the right side of the grain carrier plate 3 should be below the unloading inlet). Then, the storage and unloading assembly 2 begins to unload the grain. Simultaneously, the first translation component drives the grain carrier plate 3 to move horizontally to the right, ensuring that the grain is evenly spread from right to left on the grain carrier plate 3. During this process, the evenly spreading and scraping component 4 can be adjusted to ensure the grain is evenly spread on the grain carrier plate 3. After spreading is complete... The first translation component moves the grain carrier plate 3 back between the two sets of cameras 5 (so that the middle part of the grain carrier plate 3 is between the two sets of cameras 5). Next, the two sets of cameras 5 take pictures of the upper and lower surfaces of the grain material on the grain carrier plate 3 from above and below, and feed the images back to the vision system for analysis. After the analysis is completed, the second translation component moves the material leveling and scraping component 4 from left to right on the grain carrier plate 3, hanging the grain material on the grain carrier plate 3 from the right side onto the collection and weighing component 6. The material is weighed in the collection and weighing component 6, and after weighing, the grain material is taken out through the discharge port at the bottom of the machine box 1. The entire device has a reasonable structural design and can automatically and continuously complete the processes of grain feeding, storage, unloading, detection, dropping, weighing, and collection. The detection efficiency is high and the results are accurate.
[0031] In this embodiment, the machine vision system is a conventional technology in the field and will not be described in detail here.
[0032] In this embodiment, the chassis 1 includes a frame 11 and a housing 12 covering the frame 11. The upper side of the housing 12 is provided with a door that can be opened or closed (e in the figure).
[0033] As a preferred implementation method, such as Figure 3 As shown, the aforementioned material storage and unloading assembly 2 includes a feeding bin 21, a buffer bin 22, a first gate assembly 23, a second gate assembly 24, and a belt conveyor 25. The feeding bin 21 is open at both the upper and lower ends, with its upper opening located below the feed inlet. The first gate assembly 23 is installed at the lower end of the feeding bin 21 and is used to open or close the lower opening of the feeding bin 21. The buffer bin 22 is open at both the upper and lower ends, with its upper opening connected to the lower opening of the feeding bin 21. A grain outlet is provided on the lower right side of the buffer bin 22. The belt conveyor 25 is installed at the lower opening of the buffer bin 22, with the lower end of the buffer bin 22 in contact with the conveying surface of the belt conveyor 25. The second gate assembly 24 is located at the grain outlet and is used to open or close the grain outlet. The discharge end of the belt conveyor 25 extends above the grain carrier plate 3.
[0034] In the above implementation scheme, when feeding grain, the first gate assembly 23 and the second gate assembly 24 are closed first, and the grain falls into the feeding hopper 21 through the feed inlet. After feeding is completed, the first gate assembly 23 is opened, and the grain falls into the buffer hopper 22 and onto the conveying surface of the belt conveyor 25. Next, the second gate assembly 24 is opened, the belt conveyor 25 is running, and its conveying surface moves the grain to the right through the grain outlet and onto the waiting grain carrier plate 3 from its discharge end. After feeding is completed, the second gate assembly 24 is closed, and the grain carrier plate 3 is moved horizontally between the two sets of cameras 5 for detection.
[0035] It should be noted that: at the same time the second gate assembly 24 opens, the first gate assembly 23 closes. After closing, the next batch of grain can be put into the feed hopper 21 for testing. The two batches of grain are tested sequentially and will not be mixed.
[0036] In this embodiment, both the first gate assembly 23 and the second gate assembly 24 can be electric gate valves of the prior art.
[0037] As a preferred implementation method, such as Figure 5 As shown, the first translation component includes two first guide rails 81, a first motor 82, a first rack 83, and a first gear 84. The two first guide rails 81 are respectively installed on the left and right sides inside the housing 1 and extend in the left and right direction. The front and rear sides of the grain carrier plate 3 are slidably connected to the first guide rails 81 through first sliders. The first rack 83 is horizontally installed at the lower end of either the front or rear side of the grain carrier plate 3 in the left and right direction. The first motor 82 is fixedly installed on either the front or rear side of the housing 1, and the first gear 84 is coaxially mounted on its motor shaft. The first gear 84 meshes with the first rack 83.
[0038] In the above implementation scheme, the first motor 82 operates, driving the first gear 84 to rotate, thereby causing the first rack 83 and the grain carrier plate 3 connected to it to move left and right along the first guide rail 81. Its structural design is reasonable, the operation is stable, and the movement accuracy is also high.
[0039] As a preferred implementation method, such as Figure 4 As shown, the above-mentioned material leveling and scraping assembly 4 includes an annular mounting frame 41, a left scraper 42, a right scraper 43, and two sets of height adjustment mechanisms 44. The upper edges of the front and rear sides of the grain carrier plate 3 are respectively provided with baffles extending in the left and right directions. The left scraper 42 is disposed at the left and right ends of the mounting frame 41. The left scraper 42 and the right scraper 43 both extend in the front and rear direction and are vertically disposed between the baffles. The two sets of height adjustment mechanisms 44 are respectively mounted at the left and right ends of the mounting frame 41 and are connected to the left scraper 42 and the right scraper 43 in a corresponding manner. The second translation assembly is connected to the mounting frame 41.
[0040] In the above implementation scheme, the height of the corresponding left scraper 42 or right scraper 43 is adjusted by the height adjustment mechanism 44, so that the left scraper 42 or right scraper 43 moves downward to contact the grain carrier plate 3 or moves upward to separate, thereby realizing the adjustment of the spreading height of grain grains on the grain carrier plate 3 (specifically, when the lower end of the left scraper 42 or right scraper 43 is adjusted to a certain height h from the grain carrier plate 3, the spreading thickness of the grain material on it will not exceed the height h as the grain carrier plate 3 is translated). Furthermore, when the lower end of the left scraper 42 or right scraper 43 contacts the grain carrier plate 3, the grain material on the grain carrier plate 3 can be scraped as the material spreading and scraping component 4 is translated (specifically, as the material spreading and scraping component 4 moves to the right, the left scraper 42 or right scraper 43 can scrape the grain material on the grain carrier plate 3 off from the right side). This design is very reasonable and ingenious, and can realize the dual function of spreading and scraping.
[0041] In this embodiment, the height adjustment mechanism 44 can be a conventional lead screw motor (the lead screw shaft of the lead screw motor is provided with a lead screw nut, which is connected to the left and right scrapers. When the lead screw shaft rotates, the lead screw nut and the left and right scrapers do not rotate but move up and down), or an electric push rod, or other lifting mechanisms.
[0042] As a preferred implementation method, such as Figure 4 As shown, the second translation component includes two second guide rails 71, a second motor 72, a second rack 73, and a second gear 74. The two second guide rails 71 are respectively mounted on the left and right sides inside the housing 1 and extend in the left and right direction. The front and rear sides of the mounting bracket 41 are slidably connected to the second guide rails 71 through second sliders. The second motor 72 is mounted on either the front or rear side of the mounting bracket 41, with its motor axis pointing downwards and the second gear 74 coaxially mounted thereon. The second rack 73 is horizontally mounted on either the front or rear side of the mounting bracket 41 in the left and right direction and meshes with the second gear 74.
[0043] In the above implementation scheme, the second motor 72 operates, driving the second gear 74 to rotate, thereby causing the second motor 72 and the mounting bracket 41 to translate relative to the second rack 73, that is, causing the mounting bracket 41 to translate left and right along the second guide rail 71. This structure is reasonably designed, runs smoothly, and has high movement accuracy.
[0044] As a preferred implementation method, such as Figure 6As shown, the aforementioned material weighing assembly 6 includes a receiving hopper 61, a storage hopper 62, a weighing device 63, a material box 64, a mounting plate 65, and a third gate assembly 66. The weighing device 63 is mounted at the bottom of the chassis 1 (the entire assembly is mounted at the bottom of the chassis 1 via a bracket). The mounting plate 65 is horizontally mounted on the upper end of the weighing device 63. One end of the mounting plate 65 is close to the discharge port and has a discharge port at one end. The storage hopper 62 is open at both the upper and lower ends, and its lower open end is mounted above the discharge port. The storage hopper 62 is open at both the upper and lower ends, and its lower open end is connected to the upper open end of the storage hopper 62. The third gate assembly 66 is mounted at the lower open end of the storage hopper 62 and is used to open or close the lower open end of the storage hopper 62. The upper open end of the receiving hopper 61 is located below the right side of the grain carrier plate 3. The material box 64 is located below the discharge port.
[0045] In the above implementation scheme, after the grain is scraped off the right side of the grain carrier plate 3, it falls into the receiving hopper 61. From there, it falls into the storage hopper 62 (the third gate assembly 66 is pre-closed). The weighing device 63 monitors the weight of a batch of grain in real time and sends feedback to the control system. After weighing, the third gate assembly 66 opens, and the grain falls through the discharge port into the waiting material box 64 below. After the material has finished discharging, the material box 64 is removed through the discharge port. The entire structure is reasonably and ingeniously designed, effectively realizing the collection, weighing, and discharging of grain.
[0046] In this embodiment, the third gate assembly 66 can be a commercially available electric gate valve.
[0047] In this embodiment, the entire device is equipped with a control system (controller), which is connected to all electrical components in the device to achieve automated control operation.
[0048] As a preferred implementation method, such as Figure 7 As shown, it also includes a material box pulling mechanism 9. The material box pulling mechanism 9 includes a pulling base plate 91, a pulling baffle 92, a pulling guide rail 93, and an auxiliary wheel 94. The pulling base plate 91 is horizontally arranged, the pulling baffle 92 is vertically installed at one end of the pulling base plate 91, the material box 64 is installed at the upper end of the pulling base plate 91, the pulling guide rail 93 is horizontally installed at the lower end of the pulling base plate 91, and the bottom wall of the housing 1 is provided with a slide 95 adapted to the pulling guide rail 93. The auxiliary wheel 94 is installed at the lower part of the other end of the pulling base plate 91 and rolls in contact with the bottom wall of the housing 1. The pulling baffle 92 can drive the pulling base plate 91 and the pulling guide rail 93 to move relative to the slide 95 through the discharge port under the action of external force, and move the material box 64 to below the discharge port, or pull it out from the discharge port.
[0049] In the above implementation scheme, when the material box pulling mechanism 9 pushes the material box 64 below the discharge port, the pulling baffle 92 precisely blocks the discharge port. After the material is discharged, the pulling baffle 92 is pulled outward, and the pulling guide rail 93 slides relative to the slide block 95. The material box 64 is then moved out of the discharge port until it is removed. The material box 64 is then removed, the grain is emptied, and it is placed back (or an empty material box 64 is placed). The material box pulling mechanism 9 is then operated to push it back into the discharge port. This design facilitates the placement and removal of the material box 64, making the operation very convenient.
[0050] In this embodiment, both sets of cameras 5 are equipped with light sources at their lenses. The light sources are connected to the control system, and when the cameras 5 take pictures, the light sources are turned on or provide supplementary lighting, making the images captured by the cameras 5 clearer and the detection results more accurate.
