Description

Technical Field

[0001] This utility model relates to the field of agricultural production technology, specifically a wheat grain counting device. Background Technology

[0002] In agricultural production, grain processing, and seed breeding, wheat grain counting is a crucial foundational task, and its accuracy directly affects the accuracy of core processes such as yield estimation, seed quality testing, and breeding screening.

[0003] In small- and medium-scale agricultural production, manual counting is the main method for counting wheat grains. However, this method is extremely inefficient, which can seriously affect the progress of production and experiments. Furthermore, it has a high error rate and is easily affected by subjective factors. Prolonged operation can cause visual fatigue and distraction among workers, leading to omissions, duplicates, and incorrect counts. This method cannot meet the needs of high-precision scenarios such as seed quality testing. With the development of agricultural mechanization, semi-automatic wheat grain counting equipment based on mechanical vibration and photoelectric sensing principles has emerged on the market. However, these devices are difficult to integrate counting and screening, so further technological improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a wheat grain counting device that facilitates the counting of wheat grains and allows for the screening of wheat grains during the counting process, thereby ensuring the quality of the wheat grains.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a wheat grain counting device, including a support, a frame rotatably connected to the support, a driving device for controlling the tilt of the frame on the support, a counting plate fixedly connected inside the frame, multiple sets of placement slots on the counting plate, multiple sets of through holes communicating with the placement slots on the counting plate, an air jet pipe fixedly connected to the end of each through hole away from the placement slot, an intelligent control valve installed on each air jet pipe, an input end of each intelligent control valve connected to a gas supply pipe, the input ends of multiple gas supply pipes connected to a centralized gas supply pipe, a gas supply device for supplying gas to the centralized gas supply pipe installed on the support, and a visual inspection device on the frame.

[0006] Preferably, the driving device includes a drive motor fixedly mounted on the bracket, and the output end of the drive motor passes through the bracket and is fixedly connected to the frame.

[0007] Preferably, the gas supply device includes a gas pump, the output end of which is fixedly connected to a telescopic pipe, and the other end of the telescopic pipe is connected to the input end of a centralized gas supply pipe.

[0008] Preferably, a mounting bracket is fixedly connected to the frame, and the visual inspection device includes a color sorting camera and a supplementary light fixedly mounted on the mounting bracket.

[0009] Preferably, a control box is fixedly connected to the bracket, and the drive device, intelligent control valve, air supply device, and visual inspection device are all electrically connected to the control box via wires. The control box integrates a deep learning-based image analysis system, which performs real-time analysis of the acquired images using a pre-trained deep learning model.

[0010] Preferably, the frame has a discharge port, which is located above the counting plate.

[0011] Preferably, a collection box is detachably installed on the frame, the collection box is provided with an inlet corresponding to the discharge port, and an inclined plate is fixedly connected inside the collection box.

[0012] Preferably, a base plate is fixedly connected to the bottom surface of the bracket, and multiple mounting holes are provided on the base plate, with the air pump mounted on the base plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the counting plate with its placement slots can be used to place wheat grains for counting, which is simple and quick to use. The visual inspection device, used in conjunction with the counting plate, can detect whether the wheat grains on the counting plate are placed completely. When wheat grains are missing, it can provide an alert to ensure the accuracy of counting. At the same time, the visual inspection device can also identify wheat grains that do not meet the requirements, and after identification, it can quickly locate the placement slot where the grain is located. By controlling the intelligent control valve on the corresponding jet pipe, gas is precisely released so that the gas acts directly on the unqualified wheat grains and blows them out of the placement slot. With the help of the drive device to tilt the frame, the blown wheat grains can be moved outward, which significantly improves the quality of screening and counting. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-5 As shown, this utility model provides a wheat grain counting device, including a support 1. A base plate 19 is fixedly connected to the bottom surface of the support 1. The base plate 19 has multiple mounting holes, which allow the device to be placed stably for use. A frame 2 is rotatably connected to the support 1. A drive device for controlling the tilt of the frame 2 is provided on the support 1. The drive device includes a drive motor 3 fixedly mounted on the support 1. The output end of the drive motor 3 passes through the support 1 and is fixedly connected to the frame 2. Powered by the drive motor 3, the frame 2 can be rotated and tilted on the support 1.

[0019] A counting plate 4 is fixedly connected inside the frame 2. Multiple sets of placement slots 5 are provided on the counting plate 4. These slots 5 can be used to place wheat grains, allowing for counting of the grains. The counting plate 4 has multiple sets of through holes 6 connected to the placement slots 5. Each through hole 6, away from the placement slot 5, is fixedly connected to a jet pipe 7. Each jet pipe 7 is equipped with an intelligent control valve 8. The input ends of each intelligent control valve 8 are connected to a common gas supply pipe 9. The input ends of multiple gas supply pipes 9 are connected to a centralized gas supply pipe 10. A gas supply device for supplying gas to the centralized gas supply pipe 10 is installed on the bracket 1. The gas supply device includes an air pump 11, which is mounted on the base plate 19. The output end of the air pump 11 is fixedly connected to a telescopic pipe 12, the other end of which is connected to the input end of the centralized gas supply pipe 10.

[0020] Compressed gas can be generated by the air pump 11. The generated gas can be sent into the centralized gas supply pipeline 10 through the telescopic pipe 12. Then, the gas can be evenly distributed to the gas delivery pipeline 9 and the jet pipeline 7. The opening and closing of the jet pipeline 7 can be controlled by the intelligent control valve 8 on the jet pipeline 7. When the intelligent control valve 8 is open, the gas can be blown into the corresponding placement slot 5 through the jet pipeline 7 and the through hole 6, which can blow the wheat grains placed inside out.

[0021] A visual inspection device is installed on the frame 2. A mounting bracket 16 is fixedly connected to the frame 2. The visual inspection device includes a color sorting camera 17 and a supplementary light 18 fixedly mounted on the mounting bracket 16. A control box is fixedly connected to the bracket 1. The drive device, intelligent control valve 8, air supply device, and visual inspection device are all electrically connected to the control box via wires. When in use, the visual inspection device provides uniform and stable illumination to the placement area on the counting plate 4 through the supplementary light 18 to eliminate the influence of uneven light on the detection accuracy. Then, the color sorting camera 17 can acquire images of all placement slots 5 on the counting plate 4. The control box integrates a deep learning-based image analysis system. This system analyzes the acquired images in real time through a pre-trained deep learning model. The deep learning model adopts a convolutional neural network structure and is trained with a large amount of wheat grain image data. It can accurately identify the presence state of wheat grains in each placement slot 5 and automatically determine whether the wheat grains meet the quality requirements based on the fusion analysis of multiple features such as color, shape, and texture. For example, it can accurately identify unqualified wheat grains such as insect-damaged grains, shriveled grains, and broken grains. Compared to traditional image comparison methods, deep learning models offer higher recognition accuracy and adaptability, effectively handling the impact of diverse wheat grain shapes and varying lighting conditions. If the deep learning model detects a missing wheat grain in a placement slot 5, it sends a "missing signal" to the control box. The control box then alerts staff via audio and visual cues, allowing for re-detection after wheat grains are replenished, ensuring accurate counting. If a defective wheat grain is detected, the system can precisely locate its position in placement slot 5 using an image and record the corresponding air jet pipe 7. This allows for the subsequent opening of the appropriate intelligent control valve 8, which injects gas to blow the wheat grain out and remove it.

[0022] A discharge port 13 is provided on the frame 2, positioned above the counting plate 4. A collection box 14 is detachably installed on the frame 2, with an inlet corresponding to the discharge port 13. An inclined plate 15 is fixedly connected inside the collection box 14. In use, by tilting the frame 2 towards the discharge port 13, the blown-out substandard wheat grains move along the surface of the counting plate 4 towards the discharge port 13 under the influence of gravity and the tilt of the frame 2, eventually falling into the collection box 14 below. The inclined plate 15 inside the collection box 14 prevents the wheat grains from detaching from the collection box 14, facilitating subsequent centralized cleaning.

[0023] In use, the drive motor 3 can be operated through the control box to rotate the frame 2 to a horizontal position, ensuring that the counting plate 4 remains stable and providing a stable plane for placing wheat grains. Then, the staff can evenly place the wheat grains to be counted into multiple sets of placement slots 5 in the counting plate 4. Each set of placement slots 5 corresponds to a fixed position of the wheat grain to be counted. The initial positioning of the wheat grains is achieved through physical limiting, avoiding the wheat grains from rolling around and causing counting deviations. During this process, the control box controls the air supply device to start, and the air pump 11 generates compressed gas, which is delivered to the centralized air supply pipeline 10 through the telescopic pipe 12, and then distributed to each jet pipe 7. At this time, the intelligent control valve 8 on all jet pipes 7 is in the closed state, and the gas is temporarily stored in the pipeline. Afterwards, the color sorting camera 17 and the supplementary light 18 are used to collect images of the wheat grains in all placement slots 5 on the counting plate 4. The deep learning-based image analysis system in the control box processes the collected images in real time and automatically identifies the existence and quality status of the wheat grains in each placement slot 5 through the deep learning model. If there are no wheat grains in a certain placement slot 5, the system can send a corresponding signal to the control box to prompt the staff to replenish them, ensuring the accuracy of the counting base.

[0024] Meanwhile, based on multi-feature analysis using a deep learning model, the system can efficiently identify whether the wheat grains in the placement trough 5 meet the quality requirements. If unqualified wheat grains are detected, the system accurately determines their location in the placement trough 5 using image positioning technology. Then, the control box sends a command to the intelligent control valve 8 on the corresponding jet pipe 7 to open it. The compressed gas in the centralized air supply pipe 10 acts directly on the unqualified wheat grains through the jet pipe 7 and the through hole 6, blowing them out of the placement trough 5. Then, the drive motor 3 works again, causing the frame 2 to tilt towards the discharge port 13. Under the action of gravity and the tilt of the frame 2, the blown-out unqualified wheat grains can move along the surface of the counting plate 4 towards the discharge port 13, and finally fall into the collection box 14 below through the discharge port 13 for easy subsequent centralized cleaning.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
