[0002] For grain purchase and storage, there are general index requirements such as moisture content and impurities, as well as processing quality requirements such as imperfect grains, morphological consistency, and gluten in wheat. Therefore, quality detection is required during purchase and storage. In the related prior art, the inspection ability during grain purchase and storage is weak, the detection results are subjective, time-consuming, and the control ability is insufficient. Summary of the Invention

[0003] The present invention aims to solve at least one of the above technical problems in the prior art. For this purpose, the present invention provides a grain detection device that can automatically perform quality detection of grains and solve the deficiency of subjective detection results.

[0004] The grain detection device according to the first aspect embodiment of the present invention includes: A feeding mechanism, the feeding mechanism includes a first measuring cylinder and a second measuring cylinder, the first measuring cylinder has a set capacity, and the bottoms of the first measuring cylinder and the second measuring cylinder are transparently arranged; A first detection mechanism, the first detection mechanism includes a bulk density detection module and a near-infrared detection module; A first conveying mechanism, the feeding end of the first conveying mechanism is docked with the feeding mechanism; A second conveying mechanism, the feeding end of the second conveying mechanism is docked with the feeding mechanism, and a visual detection component is arranged on the second conveying mechanism; A third conveying mechanism, the third conveying mechanism is simultaneously docked with the discharging end of the first conveying mechanism and the discharging end of the second conveying mechanism, and the third conveying mechanism has a first output end and a second output end; A second detection mechanism, the second detection mechanism is docked with the first output end and is used to detect the safety index of the incoming object; Among them, the grain detection device can hold the grain with the set capacity through the first measuring cylinder, hold the grain through the second measuring cylinder, control the first measuring cylinder and the second measuring cylinder to pass through the near-infrared detection module in sequence for near-infrared detection through the feeding mechanism, and control the first measuring cylinder to pass through the unit weight detection module for unit weight detection; then send the grain in the first measuring cylinder into the third conveying mechanism through the first conveying mechanism, send the grain in the second measuring cylinder into the second conveying mechanism, and send it into the third conveying mechanism after being detected by the visual detection component; the third conveying mechanism sends at least part of the grain in the first measuring cylinder and / or the second measuring cylinder from the first output end into the second detection mechanism to perform safety index detection, and sends the remaining grain out from the second output end.

[0005] The grain detection device according to the embodiment of the present invention has at least the following beneficial effects: When the grain detection device of this embodiment works, it uses the first measuring cylinder to hold the grain with the set capacity, uses the second measuring cylinder to hold a certain amount of grain, and can obtain the water content by performing near-infrared detection on the grain in the first measuring cylinder and the second measuring cylinder, and then judge the dryness of the grain. Then, perform unit weight detection on the grain in the first measuring cylinder to obtain the plumpness, water content, etc. of the grain. After the detection is completed, the grain in the first measuring cylinder and the second measuring cylinder are respectively poured into the first conveying mechanism and the second conveying mechanism. The visual detection component on the second conveying mechanism can perform particle size integrity detection. Finally, part of the grain is sent from the first output end to the second detection mechanism for safety index detection, such as safety indexes like pesticide residues, while the remaining grain is discharged from the second output end.

[0006] The grain detection device of this embodiment divides the sampled grain into a first sample with a known capacity held by the first measuring cylinder and a second sample with an undetermined capacity held by the second measuring cylinder, and performs near-infrared detection on both the first sample and the second sample, so as to obtain two sets of detection data of the same batch of grain, ensuring the objectivity and accuracy of the detection results. At the same time, perform unit weight detection on the first sample to obtain the plumpness and other conditions of this batch of grain. In practical applications, the first measuring cylinder and the second measuring cylinder can have the same structure and size. Therefore, the grain held by the first measuring cylinder is more than that held by the second measuring cylinder. The first conveying mechanism can quickly send the grain in the first measuring cylinder into the third conveying mechanism, while the second sample with less quantity completes visual detection during the conveying process of the second conveying mechanism. Because of its small quantity, it is easier to be evenly dispersed for detection. Finally, the third conveying mechanism can quickly discharge the first sample from the second output end, send the second sample into the second detection mechanism for safety index detection, or select to send part of the first sample quickly sent into the third conveying mechanism into the second detection mechanism, or send part of the second sample into the second detection mechanism.

Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0024] Referring to Figures 1 to 9 , an embodiment of the present invention provides a grain detection device, including: A feeding mechanism 100, the feeding mechanism 100 includes a first measuring cylinder 101 and a second measuring cylinder 102. The first measuring cylinder 101 has a set capacity, and the bottoms of the first measuring cylinder 101 and the second measuring cylinder 102 are transparently provided; A first detection mechanism, the first detection mechanism includes a bulk density detection module 602 and a near-infrared detection module 601; A first conveying mechanism 200, the feeding end of the first conveying mechanism 200 is docked with the feeding mechanism 100; The second conveying mechanism 300, the feeding end of the second conveying mechanism 300 is butted against the feeding mechanism 100, and a vision detection component 700 is arranged on the second conveying mechanism 300; The third conveying mechanism 400, the third conveying mechanism 400 is butted against the discharging end of the first conveying mechanism 200 and the discharging end of the second conveying mechanism 300 at the same time, and the third conveying mechanism 400 has a first output end and a second output end; The second detection mechanism 500, the second detection mechanism 500 is butted against the first output end and is used for detecting the safety index of the incoming object.

[0025] Among them, the grain detection device can hold a set volume of grain through the first measuring cylinder 101, hold grain through the second measuring cylinder 102, control the first measuring cylinder 101 and the second measuring cylinder 102 to pass through the near-infrared detection module 601 in sequence for near-infrared detection through the feeding mechanism 100, and control the first measuring cylinder 101 to pass through the volumetric weight detection module 602 for volumetric weight detection; then send the grain in the first measuring cylinder 101 into the third conveying mechanism 400 through the first conveying mechanism 200, send the grain in the second measuring cylinder 102 into the second conveying mechanism 300, and send it into the third conveying mechanism 400 after being detected by the vision detection component 700; the third conveying mechanism 400 sends at least part of the grain in the first measuring cylinder 101 and / or the second measuring cylinder 102 from the first output end into the second detection mechanism 500 for safety index detection, and sends the remaining grain out from the second output end.

[0026] For the grain detection device of this embodiment, by dividing the sampled grain into a first sample with a known volume held by the first measuring cylinder 101 and a second sample with an undetermined volume held by the second measuring cylinder 102, and performing near-infrared detection on both the first sample and the second sample, two sets of detection data of the same batch of grain can be obtained, ensuring the objectivity and accuracy of the detection results. At the same time, by performing volumetric weight detection on the first sample, the plumpness and other conditions of this batch of grain can be obtained.

[0027] In practical applications, the first measuring cylinder and the second measuring cylinder can have the same structure and size. Therefore, the grain held by the first measuring cylinder is more than that held by the second measuring cylinder. The first conveying mechanism 200 can quickly send the grain in the first measuring cylinder 101 into the third conveying mechanism 400. For the second sample with a small amount, the vision detection is completed during the conveying process of the second conveying mechanism 300. Since its amount is small, it is easier to be evenly dispersed for detection.

[0028] Finally, the third conveying mechanism 400 can quickly discharge the first sample from the second output end, send the second sample into the second detection mechanism 500 for safety index detection, or choose to send part of the first sample quickly sent into the third conveying mechanism 400 into the second detection mechanism 500, or send part of the second sample into the second detection mechanism 500. Since the first sample and the second sample may fall into the third conveying mechanism 400 at the same time, which sample is specifically sent into the second detection mechanism 500 is not restricted, and in practical applications, the timing of the third conveying mechanism 400 sending the sample into the second detection mechanism 500 can be flexibly set according to needs.

[0029] Therefore, the grain detection equipment in the present invention can automatically and efficiently detect multiple qualities of grains, can be applied to detect grains during grain storage, and solves the defects of subjectivity in manual detection, as well as insufficient efficiency and insufficient control.

[0030] It can be understood that the grain detection equipment of this embodiment uses the first measuring cylinder 101 to hold a set volume of grains, uses the second measuring cylinder 102 to hold a certain amount of grains, and can obtain the moisture content by performing near-infrared detection on the grains in the first measuring cylinder 101 and the second measuring cylinder 102, and then judge the dryness of the grains. Then, the specific gravity of the grains in the first measuring cylinder 101 is detected. Since the volume of the first measuring cylinder 101 is determined, the plumpness, moisture content, etc. of the grains can be quickly and accurately obtained. After the detection is completed, the grains in the first measuring cylinder 101 and the second measuring cylinder 102 are respectively poured into the first conveying mechanism 200 and the second conveying mechanism 300. The visual detection component 700 on the second conveying mechanism 300 can perform particle integrity detection. The grains are sent out from the second output end through the third conveying mechanism 400, and at the same time, part of the grains can be sent from the first output end to the second detection mechanism 500 for safety index detection, such as safety indexes such as pesticide residues, aflatoxin, and vomitoxin.

[0031] Refer to Figure 4 , in some embodiments of the present invention, the feeding mechanism 100 further includes a handling component. The handling component is provided with a first clamping portion 1011 and a second clamping portion 1021 for clamping the first measuring cylinder 101 and the second measuring cylinder 102 respectively. And the handling component includes a translational motion pair 104 and a rotational motion pair 105. Among them, the translational motion pair 104 is used to control the first measuring cylinder 101 to approach the near-infrared detection module 601 and the specific gravity detection module 602 in sequence, and control the second measuring cylinder 102 to approach the near-infrared detection module 601; while the rotational motion pair 105 is used to control the first measuring cylinder 101 and the second measuring cylinder 102 to flip so as to send the contained grains to the first conveying mechanism 200 and the second conveying mechanism 300 respectively.

[0032] During operation, when the first clamping part 1011 and the second clamping part 1021 clamp the first measuring cylinder 101 and the second measuring cylinder 102, the feeding mechanism 100 controls the movement of the first measuring cylinder 101 and the second measuring cylinder 102 to be placed on the bulk density detection module 602 and the near-infrared detection module 601 through the translational kinematic pair 104, and then clamps the first measuring cylinder 101 and the second measuring cylinder 102 and moves them out after the detection is completed. During the movement process, the translation in the horizontal and vertical directions can be combined, and it is not limited to one direction. After the detection is completed, when the feeding mechanism 100 clamps the first measuring cylinder 101 and the second measuring cylinder 102, the first measuring cylinder 101 and the second measuring cylinder 102 are controlled to be flipped and tilted towards the first conveying mechanism 200 and the second conveying mechanism 300 through the rotational kinematic pair 105, and the grains are poured onto the first conveying mechanism 200 and the second conveying mechanism 300.

[0033] Specifically, the translational kinematic pair 104 includes a double-axis slide rail assembly. The double-axis slide rail assembly can translate along the X direction and the Z direction, and its specific translation structure can be set by using the structures in the relevant prior art, and no specific limitation is made here. The rotational kinematic pair 105 is arranged on the double-axis slide rail assembly and can move along the X direction and the Z direction under the drive of the double-axis slide rail assembly. The handling assembly is arranged at the driving end of the rotational kinematic pair 105, so that the first clamping part 1011 and the second clamping part 1021 can be flipped under the control of the rotational kinematic pair 105. The flipping driving form of the rotational kinematic pair 105 and the clamping forms of the first clamping part 1011 and the second clamping part 1021 can both be set with reference to the relevant prior art, and no specific elaboration is made here.

[0034] When pouring the first measuring cylinder 101 and the second measuring cylinder 102, they can be poured synchronously or independently. Those skilled in the art can flexibly set according to needs.

[0035] Refer to Figure 2 and Figure 5 , in some embodiments of the present invention, along the X direction, the second clamping part 1021, the first clamping part 1011, the near-infrared detection module 601, and the bulk density detection module 602 are equally spaced. In this way, when the handling assembly moves the first measuring cylinder 101 to the bulk density detection module 602, the second measuring cylinder 102 can be synchronously moved to the near-infrared detection module 601. When the handling assembly moves the first measuring cylinder 101 to the near-infrared detection module 601, the second measuring cylinder 102 can be synchronously moved to the original position of the first measuring cylinder 101, which is convenient for feeding the grains from the original position of the first measuring cylinder 101 into the first measuring cylinder 101 and the second measuring cylinder 102.

[0036] Furthermore, the feeding mechanism 100 also includes a material taking barrel 103, which is located above the conveying assembly and can dock with the first measuring cylinder 101 and the second measuring cylinder 102 one by one. The capacity of the material taking barrel 103 is greater than the set capacity of the first measuring cylinder 101, and a valve plate 1031 capable of horizontal opening and closing adjustment is provided at the bottom of the material taking barrel 103. The grain detection device uses the material taking barrel 103 to hold grain greater than the set capacity, first controls the material taking barrel 103 to dock with the first measuring cylinder 101, so that the first measuring cylinder 101 holds the set capacity of grain, and then controls the material taking barrel 103 to dock with the second measuring cylinder 102, and pours the remaining grain into the second measuring cylinder 102.

[0037] It is understandable that, since the first measuring cylinder 101 and the second measuring cylinder 102 can move along the X direction, the material taking cylinder 103 can dock with the first measuring cylinder 101 and the second measuring cylinder 102 through the movement of the first measuring cylinder 101 and the second measuring cylinder 102. In order to improve flexibility, the material taking cylinder 103 can be equipped with a Y-direction slide rail for movement and a Z-direction slide rail for movement.

[0038] In this embodiment, the capacity of the material taking cylinder 103 is greater than the set capacity, so that each sampling can ensure that the first measuring cylinder 101 contains the set capacity of grain, thereby ensuring the detection result.

[0039] During operation, the staff pours grain larger than the set capacity into the material taking cylinder 103, and then aligns and docks the material taking cylinder 103 with the first measuring cylinder 101, and then opens the valve plate 1031, and the grain fills the first measuring cylinder 101 under the action of gravity, and the valve plate 1031 is closed again. At this time, the first measuring cylinder 101 is filled with the set capacity of grain, and then the material taking cylinder 103 is docked with the second measuring cylinder 102 to discharge the remaining grain into the second measuring cylinder 102.

[0040] Reference Figure 6 In some embodiments of the present invention, the first conveying mechanism 200 includes: First receiving hopper 201; A first conveyor belt 202, the first conveyor belt 202 is located below the first receiving hopper 201; The first material leveling component 203 is disposed above the first conveyor belt 202 and defines a material leveling space between the first material leveling component 203 and the first conveyor belt 202 .

[0041] When the first measuring cylinder 101 pours the grain, the first receiving hopper 201 receives the poured grain and collects the grain onto the first conveyor belt 202 for transportation. During the transportation, the first material leveling component 203 evenly spreads the grain so that the grain is spread flat on the first conveyor belt 202 to maintain a uniform thickness.

[0042] Among them, the first material leveling assembly 203 includes a plurality of first material leveling plates. The plurality of first material leveling plates are arranged at intervals along the conveying direction of the first conveyor belt 202, and each first material leveling plate can be adjusted up and down to define a material leveling space with different heights. Along the conveying direction of the first conveyor belt 202, the distance between the plurality of first material leveling plates and the first conveyor belt 202 gradually decreases, so that the thickness of the grain is gradually pressed layer by layer until it is spread flat on the first conveyor belt 202 during conveying.

[0043] Further, a first adjusting plate for adjusting the opening degree is provided at the discharging end of the first receiving hopper 201 to adjust the feeding speed through the first adjusting plate.

[0044] Referring to Figure 6 and Figure 7 , in some embodiments of the present invention, the second conveying mechanism 300 includes: A second receiving hopper 301; A second conveyor belt 302, and the second conveyor belt 302 is located below the first receiving hopper 201; A second material leveling assembly 303, and the second material leveling assembly 303 is arranged above the second conveyor belt 302 and defines a material leveling space with the second conveyor belt 302; The visual inspection assembly 700 is arranged at the discharging end of the second conveyor belt 302.

[0045] The grain poured out of the second measuring cylinder 102 is received by the second receiving hopper 301 and gathered on the second conveyor belt 302, and is conveyed by the second conveyor belt 302. During the conveying process, it is leveled by the second material leveling assembly 303 and spread flat on the second conveyor belt 302.

[0046] Specifically, the second material leveling assembly 303 includes a plurality of second material leveling plates. The plurality of second material leveling plates are arranged at intervals along the conveying direction of the second conveyor belt 302, and each second material leveling plate can be adjusted up and down to define a material leveling space with different heights. Along the conveying direction of the second conveyor belt 302, the distance between the plurality of second material leveling plates and the second conveyor belt 302 gradually decreases, so that the thickness of the grain is gradually pressed layer by layer until it is spread flat on the second conveyor belt 302 during conveying.

[0047] Further, a second adjusting plate 3011 for adjusting the opening degree is provided at the discharging end of the second receiving hopper 301 to adjust the feeding speed through the second adjusting plate 3011.

[0048] Moreover, the first conveying mechanism 200 and the second conveying mechanism 300 are spaced apart along the X direction, and the spacing distance is equal to the distance between the first measuring cylinder 101 and the second measuring cylinder 102, so that the first measuring cylinder 101 and the second measuring cylinder 102 can simultaneously pour grain into the first conveying mechanism 200 and the second conveying mechanism 300.

[0049] In some embodiments of the present invention, the visual detection component 700 includes: A weighing module 702, with a weighing platform that can be turned upwards provided at the upper end of the weighing module 702; A visual module 701, which is arranged above the weighing module 702.

[0050] Wherein the height of the weighing platform is lower than that of the second conveyor belt 302, so that the grains conveyed by the second conveyor belt 302 can be directly sent onto the weighing platform. Since the grains on the second conveyor belt 302 are already evenly spread out, the weight of the grains fed onto the weighing platform can be effectively controlled when feeding, so that each time visual detection is performed, the grains of the same weight are detected. After the grains are fed onto the weighing platform, the upper visual module 701 takes pictures of the grains, and the particle size integrity detection can be clearly carried out.

[0051] After the detection is completed, the grains can be discharged by turning the weighing platform upwards.

[0052] Furthermore, the weighing module 702 is also configured with a vibration module to ensure that the grains are spread out flat on the weighing platform, facilitating visual detection.

[0053] And the weighing module 702 can move between the second conveyor belt 302 and the third conveying mechanism 400, which is beneficial to improving the conveying efficiency.

[0054] Refer to Figure 8 , in some embodiments of the present invention, the visual detection component 700 includes a weighing module 702, and a cleaning frame 703 that can be adjusted in height and lowered is provided on the peripheral side of the upper end of the weighing module 702. A cleaning brush 704 is provided at the bottom of the side of the cleaning frame 703 away from the third conveying mechanism 400. Support seats 7031 are provided on the opposite sides of the cleaning frame 703 to connect to the slide rails for translation relative to the weighing module 702.

[0055] During operation, the cleaning frame 703 is lower than the upper end of the weighing module 702, so that the grains are smoothly fed onto the weighing module 702, and then the cleaning frame 703 rises to protrude upwards relative to the upper end of the weighing module 702, forming a circle of limit on the peripheral side of the upper end surface of the weighing module 702. Vibration is started to evenly disperse the grains for facilitating visual detection. After the visual detection is completed, the cleaning frame 703 continues to rise until the cleaning brush 704 is docked with the upper end surface of the weighing module 702, and then the cleaning frame 703 moves along the conveying direction of the second conveying mechanism 300, and the cleaning brush 704 is used to push all the grains onto the third conveying mechanism 400.

[0056] A working process of the grain detection equipment of the present application includes: First, the sampled grain is fed into the material taking cylinder 103, and the sampling capacity is greater than the set capacity of the first measuring cylinder 101 and less than the sum of the capacities of the first measuring cylinder 101 and the second measuring cylinder 102. Move the material taking cylinder 103 above the first measuring cylinder 101 to dock with the first measuring cylinder 101. After filling the first measuring cylinder 101, move the first measuring cylinder 101 to the near-infrared detection module 601 for near-infrared detection, and synchronously move the second measuring cylinder 102 to the original position of the first measuring cylinder 101 so that the second measuring cylinder 102 is aligned with the material taking cylinder 103, and pour the remaining grain in the material taking cylinder 103 into the second measuring cylinder 102. After the first measuring cylinder 101 finishes the near-infrared detection, move the first measuring cylinder 101 to the volumetric weight detection module 602 for volumetric weight detection, and synchronously move the second measuring cylinder 102 to the near-infrared detection module 601 for near-infrared detection. After both the first measuring cylinder 101 and the second measuring cylinder 102 finish the detection, move the first measuring cylinder 101 and the second measuring cylinder 102 to the feeding ends of the first conveying mechanism 200 and the second conveying mechanism 300 respectively, and synchronously flip the first measuring cylinder 101 and the second measuring cylinder 102 to pour the grain into the first conveying mechanism 200 and the second conveying mechanism 300 respectively. Use the first conveying mechanism 200 to evenly convey the grain in the first measuring cylinder 101 to the third conveying mechanism 400, and use the second conveying mechanism 300 to convey a set weight of grain to the visual detection component 700 for visual detection. After the detection is completed, send the grain to the third conveying mechanism 400. Use the third conveying mechanism 400 to send part of the grain to the second detection mechanism 500 for safety index detection, and send the remaining grain out.

[0057] The grain that can be detected in the present invention can be wheat or other varieties of grain.

[0058] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
