Description

Technical Field

[0001] This application relates to the field of grain inspection equipment technology, and in particular to a smart grain inspection device. Background Technology

[0002] The statements in this section are merely background information related to this application and do not necessarily constitute prior art.

[0003] Grain inspection technology plays a crucial role in agricultural production and the food industry. Currently, the detection of abnormal grain particles mainly relies on technologies such as computer vision and image processing. Within this framework, grain inspection systems typically require vision cameras. However, existing technologies often only capture partial images of the grain, leading to omissions in the inspection results. Furthermore, it is difficult to distinguish abnormal grains, such as imperfect grains, insect-damaged grains, and moldy grains. On the other hand, current grain inspection technologies have a low degree of automation, often relying on manual intervention, such as classifying and screening grains by visual inspection. This reliance on manual intervention not only reduces inspection efficiency but also increases system maintenance and management costs. Moreover, manual vision methods are easily affected by environmental changes such as lighting conditions and grain angles, leading to instability in the detection process.

[0004] Therefore, it is necessary to provide a smart grain inspection device to solve the above-mentioned technical problems. Summary of the Invention

Both the main tube and branch tubes are connected to a sorting bin, and each sorting bin is equipped with a weighing sensor at the bottom.

[0014] Preferably, Each sorting bin is equipped with a valve at the bottom, and a grain recovery box is located inside the shell at the bottom of the sorting bin.

[0025] refer to Figure 1 as well as Figure 2The diagram below shows the overall structure of a smart grain inspection device according to this application. In one embodiment, the smart grain inspection device according to this application includes: Casing 14; The anti-breakage unloader 4 is connected to the grain suction hopper 7 through the suction pipe 6 and is located inside the upper part of the shell 14. The suction collection pipe 1 is located above the anti-breakage unloader 4; the suction collection pipe 1 is connected to the anti-breakage unloader 4 pipeline through the suction branch pipe 3; one end of the suction collection pipe 1 is connected to a suction fan; the suction force of the suction fan draws the grain in the grain suction hopper 7 into the anti-breakage unloader 4. The vibrating feeder 15 is located below the anti-breakage unloader 4 and is used to receive grain and vibrate and transport the grain so that it falls into the sorting pipe 16 below. The testing instrument used to detect abnormal grains includes: The sorting tube 16 is located below the vibrating feeder 15 and includes a main tube and branch tubes. Both the main tube and branch tubes are connected to a sorting bin below, and each sorting bin is equipped with a weighing sensor at the bottom. A vision camera 18 and an air blowing device are located between the sorting tube 16 and the vibrating feeder 15. When the vision camera 18 detects abnormal grains, the air blowing device activates, causing the abnormal grains to fall into the branch tubes of the sorting tube 16. Normal grains fall into the main tube of the sorting tube 16 under gravity, thus separating the abnormal and normal grains. The content of abnormal and normal grains is then determined by a weighing sensor at the bottom of the sorting bin. The abnormal grains include two of the following: imperfect grains, moldy grains, and insect-damaged grains. In some embodiments, the air blowing device is an air blowing pipe equipped with a solenoid valve for controlling the on / off state of the air blowing pipe, and the air blowing pipe is connected to an external air source pipeline.

[0026] The suction branch pipe 3 is equipped with a suction switch solenoid valve 2; a switch valve is located below the anti-breakage unloader 4; the suction switch solenoid valve 2, the suction fan, the vibrating feeder 15, the weighing sensor, the vision camera 18, and the air blowing device are all electrically connected to the control device; the air blowing device is connected to an external air source pipeline. Valves are provided at the bottom of each sorting bin, and a grain recovery box 13 is located inside the shell 14 at the bottom of the sorting bin.

[0027] The above embodiments can be used to inspect imperfect grains, moldy grains, or insect-damaged grains. In some embodiments, to inspect grain moisture and bulk density grades, refer to... Figure 1A moisture density unmanned intelligent testing instrument 5 is installed between the vibrating feeder 15 and the anti-breakage unloading device 4; the moisture density unmanned intelligent testing instrument 5 is used to test the moisture density of the grain. A distribution pipe 9 is connected below the moisture density unmanned intelligent testing instrument 5. The distribution pipe 9 includes an upper feed pipe and two lower discharge pipes. Two testing instruments for detecting abnormal grains are respectively installed below the two lower discharge pipes. Referring to reference 6, the unmanned intelligent testing instrument 5 for moisture and bulk density grades of this application includes: Grain hopper 5b; A grain bulk density tester is located below the grain hopper 5b, and a flow channel for grain to pass through is formed between the grain hopper 5b and the grain bulk density tester. The grain moisture analyzer is located on both sides of the grain bulk density analyzer; The feeder 5d is located between the grain hopper 5b and the grain bulk density tester; The unloader 5p is located below the grain bulk density tester; The feeder 5d and the discharger 5p are used to control the opening and closing of the flow channel. The purpose of this design is to enable the detection of grain moisture content during bulk density testing to determine the grain grade.

[0028] Continue to refer to Figure 6 In some embodiments, the grain bulk density tester includes a leakage box 5e and a bulk density box 5f located inside the leakage box 5e; a discharge channel 5s is formed between the leakage box 5e and the bulk density box 5f; a discharge device 5p is fixedly installed at the bottom of the leakage box 5e; the bottom of the bulk density box 5f is fixedly installed on the discharge device 5p. A weighing sensor is provided at the bottom of the bulk density box 5f, and the weighing sensor is fixedly connected to the leakage box 5e. A second material sensor 5c is fixedly installed on the outer side of the bottom of the grain hopper 5b. The purpose of setting up the discharge channel 5s is that when grain enters the bulk density box 5f inside the grain bulk density tester from the grain hopper 5b, some grain will fall into the discharge channel 5s between the bulk density box 5f and the leakage box 5e. The discharge channel 5s serves to recover this part of the grain, for example, by connecting a recovery box below the discharge channel 5s.

[0029] In this application, the inner diameter of the bulk density chamber 5f is designed to be smaller than that of the grain hopper 5b. This ensures that when grain enters the bulk density chamber 5f from the grain hopper 5b, the chamber is completely filled, guaranteeing accurate bulk density measurement. The bulk density chamber 5f is designed as a standard 1L container. When the bulk density chamber 5f is full, refer to... Figure 1If the second material sensor 5c in the figure detects a signal, the control device controls the feeding motor 5n to rotate, the feeding plate 5o separates the excess grain above the bulk density box 5f, and the weighing sensor weighs the grain in the bulk density box 5f to obtain the weight of 1L of grain.

[0030] In some embodiments, the feeder 5d includes a feed motor 5n, a feed frame 5m, and a feed plate 5o; the upper and lower sides of the feed frame 5m are fixedly connected to the grain hopper 5b and the discharge box 5e, respectively; the feed frame 5m has through holes that cooperate with the flow channel; the feed plate 5o is slidably disposed inside the feed frame 5m, with the upper end of the feed plate 5o slidingly connected to the lower end of the grain hopper 5b; the lower end of the feed plate 5o slidingly connected to the upper end of the bulk density box 5f; the feed plate 5o is driven by the feed motor 5n, and under the drive of the feed motor 5o, the feed plate 5o moves within the feed frame 5m to realize the on / off control of the flow channel.

[0031] The unloading device 5p includes an unloading motor 5i, an unloading frame 5k, and an unloading plate 5g; the upper side of the unloading frame 5k is fixedly connected to the material leakage box 5e; the unloading frame 5k has a through hole that cooperates with the flow channel; the unloading plate 5g is slidably disposed inside the unloading frame 5k, and the upper end of the unloading plate 5g is slidably connected to the lower end of the bulk density box 5f; the unloading plate 5g is driven by the unloading motor 5i, and under the drive of the unloading motor 5i, the unloading plate 5g moves within the unloading frame 5k to realize the on / off control of the flow channel.

[0032] In some embodiments, the grain moisture analyzer is a microwave moisture analyzer. (Reference) Figure 1 and Figure 2 In this application, the microwave moisture detector includes a microwave sensor 5h, which is symmetrically arranged on both sides of the material leakage box 5e; the microwave sensor 5h and the microwave speaker 5j are fixedly connected to the material leakage box 5e. The microwave moisture detector is electrically connected to the control device; the weighing sensor, the unloading motor 5i, and the feeding motor 5n are all electrically connected to the control device.

[0033] In some embodiments, a first material sensor 5a is also fixedly installed on one side of the grain hopper 5b's inlet; both the first material sensor 5a and the second material sensor 5c are electrically connected to the control device. The first material sensor 5a serves as a grain over-limit alarm, see reference... Figure 1When performing grain bulk density testing, the unloader 5p needs to be closed first, that is, the unloader plate 5g is used as the bottom plate of the bulk density box 5f, and then grain is fed into the grain hopper 5b. When the second material sensor 5c detects the grain signal, the grain feeding can be stopped, the feeder 5d can be closed, and then the bulk density and moisture of the grain can be tested. However, when the second material sensor 5c malfunctions and cannot detect the grain well, the first material sensor 5a plays the role of an over-limit alarm. When the first material sensor 5a detects the grain, it transmits the signal to the control device, and the control device issues an alarm message to remind the staff.

[0034] The above embodiments can achieve two of the following inspections: defective grains, moldy grains, or insect-damaged grains. To achieve multiple inspections, in some other embodiments, an additional set of anti-breakage unloader 4, vibrating feeder 15, sorting pipe 16, vision camera 18, and air blowing device is provided. Unlike the previous embodiment, a feeding pipe 8 is provided between the vibrating feeder 15 and the anti-breakage unloader 4. The top opening of the feeding pipe 8 is located below the anti-breakage unloader 4, and the bottom opening of the feeding pipe 8 is connected to the hopper 150 of the vibrating feeder 15. That is, the bottom opening of the feeding pipe 8 is connected to an inspection instrument for inspecting abnormal grains. An inspection instrument for inspecting abnormal grains is provided below the vibrating feeder 15.

[0035] The vibrating feeder 15 of this application, see reference. Figure 3 and Figure 4 ,include: Rack 151, The hopper 150 is located above the movable feed plate 152; the frame 151 is a shell-shaped structure with an open top, and the hopper 150 is located on the top of the frame. The vibrating feeder is used to vibrate and evenly convey the grain material coming out from below the hopper 150; the hopper 150 is fixedly connected to the frame 151. The V-groove conveyor plate 154 is fixed at one end inside the frame 151 and extends to the outside of the frame 151 at the other end. The through-type lead screw motor 153 is located above the V-groove conveyor plate 154 and is fixedly installed on one side of the frame 151; The movable feeding plate 152 is located above the V-groove conveying plate 154. One end is rotatably connected to the frame 151, and the bottom of the other end abuts against the lead screw of the through-type lead screw motor 153. When the through-type lead screw motor 153 is powered on, it drives the movable feeding plate 152 to vibrate through the lead screw, thereby realizing the vibration treatment of the grain material. In some embodiments, in order to better facilitate the conveying of grain materials by the V-groove conveyor plate 154, the V-groove conveyor plate 154 is inclined downward from one end inside the frame 151 to the other end outside the frame 151. This is because if the V-groove conveyor plate 154 is set horizontally, the grain materials can only be conveyed by "rolling" on the V-groove conveyor plate 154 by relying on the physical structure of the grain materials themselves. On the one hand, it is uncontrollable, and on the other hand, the physical structure of the grain materials themselves is irregular, resulting in poor applicability.

[0036] However, if the tilt angle of the V-groove conveyor plate 154 is too large, it will cause the grain material to be conveyed too quickly, which is not conducive to the actual detection of the grain material. Therefore, in this embodiment, the tilt angle value of the V-groove conveyor plate 154 is set. : in: This refers to the length of the V-groove conveyor plate 154. This refers to the maximum height of the material conveyed by the V-groove conveyor plate 154.

[0037] In some embodiments, the V-groove conveyor plate 154 is horizontally arranged. In this embodiment, unlike the previous embodiment, a vibrator 155 is provided at the bottom of the V-groove conveyor plate 154, and the vibrator 155 is fixedly installed inside the frame 151. The top of the vibrator 155 abuts against the bottom of the V-groove conveyor plate 154, and a shock-absorbing pad is provided at the bottom of the frame 151. Although the V-groove conveyor plate 154 is horizontally arranged, the vibrator 155 enables the conveying of grain materials on the V-groove conveyor plate 154. Furthermore, by adjusting the vibration frequency of the vibrator 155, the conveying speed of the grain materials on the V-groove conveyor plate 154 can be adjusted to a certain extent.

[0038] In some embodiments, the bottom of the V-groove conveyor plate 154 is connected to the frame 151 via a shock-absorbing device. The shock-absorbing device includes a connecting block, and the bottom of the connecting block is fixedly connected to the frame 151 via a shock-absorbing spring. The top of the connecting block is provided with a V-shaped opening that mates with the outside of the V-groove conveyor plate 154, and the V-groove conveyor plate 154 is fixedly disposed within the V-shaped opening.

[0039] In some embodiments, a photoelectric sensor 156 is fixedly installed at the bottom of one end of the V-groove conveyor plate 154 that extends outside the frame 151. After the photoelectric sensor 156 is fixed, its detection direction is horizontal, and the photoelectric sensor 156 is electrically connected to the control device.

[0040] During use, the grain material falling from the hopper 150 lands on the movable feed plate 152. Under the action of the through-type screw motor 3, the movable feed plate 152 vibrates the grain material, which then falls onto the V-groove conveyor plate 154 under gravity. If the V-groove conveyor plate 154 has an inclination angle... The grain material will then be slowly conveyed out by the V-shaped trough conveyor plate 154 and finally fall at the end of the V-shaped trough conveyor plate 154. If the V-shaped trough conveyor plate 154 has no inclination angle, the grain material will also be slowly conveyed out by the V-shaped trough conveyor plate 154 under the action of the vibrator 155 and finally fall at the end of the V-shaped trough conveyor plate 154. When the photoelectric sensor 156 detects the grain material falling, the control device receives the signal, which facilitates the control device to control the next step of grain detection and processing.

[0041] In this application, the inspection instruments for abnormal grains include an unmanned intelligent inspection instrument 10 for imperfect grains, an unmanned intelligent inspection instrument 11 for moldy grains, and an unmanned intelligent inspection instrument 12 for insect-damaged grains. The unmanned intelligent inspection instruments 10, 11, and 12 are described in detail.

[0042] To achieve multi-angle and all-round visual inspection of grains, in this application, the number of visual cameras 18 is four. Specifically, the path of the grains vibrating and conveyed by the vibrating feeder 15 falling onto the sorting pipe 16 is a vertical straight line segment. The visual cameras 18 are located in any vertical plane within the vertical straight line segment, and the visual cameras 18 are located on the four quadrant angle bisectors of the four quadrants of the Cartesian coordinate system within the vertical plane, with the straight line containing the vertical straight line segment as the Y-axis and the horizontal line within the vertical plane passing through any point on the vertical straight line segment as the X-axis.

[0043] This application provides a smart grain inspection method, based on the aforementioned smart grain inspection device, comprising the following steps: S1: Close the discharge port below the anti-breakage unloader 4, open the suction switch solenoid valve 2, power on the suction fan, and the grain in the grain suction hopper 7 is sucked into the anti-breakage unloader 4 through the suction pipe 6. S2: When the grain in the anti-breakage unloader 4 reaches the set weight, the suction fan is powered off; S3: Open the discharge port below the anti-breakage unloader 4. The grain in the anti-breakage unloader 4 enters the unmanned intelligent moisture and bulk density tester 5 to test the moisture and bulk density of the grain. S4: After completing the moisture and bulk density tests of the grain, the grain in the unmanned intelligent moisture and bulk density tester 5 falls into the distribution pipe 9; the grain entering the distribution pipe 9 enters the two vibrating feeders 15 below the two lower discharge pipes respectively. S5: The vibrating feeder 15 vibrates and conveys the grain, which falls into the sorting tube 16 below. at this time: If the vision camera 18 captures abnormal grains, the blowing device 19 starts blowing air to make the abnormal grains fall into the sorting tube 16. If the vision camera 18 does not capture abnormal grains, the air blowing device 19 will not start blowing, and the normal grains will fall into the main tube of the sorting tube 16 under the action of gravity. S6: Normal grains in the main tube and abnormal grains in the branch tube of the sorting tube 16 fall into the two sorting bins 17 below it respectively; S7: Obtain the weight of each sorting bin 17 to determine the proportion of abnormal grains in the grain.

[0044] This application discloses a highly automated intelligent grain inspection device that requires no manual intervention and can automatically complete the inspection process. It can simultaneously perform grain moisture and bulk density determination tests, as well as inspections for defective, moldy, and insect-damaged grains, providing all results in a single test. Furthermore, in terms of grain visual recognition, only four vision cameras are needed. By employing the camera placement described in this application, multi-angle and omnidirectional imaging of the grain can be achieved, solving the technical problem in existing technologies where imaging often only captures partial views of the grain, leading to missed inspection results.

[0045] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

[0046] While the specific embodiments of this application have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of this application. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of this application are still within the scope of protection of this application.
