Description

Technical Field

[0001] This application relates to the field of screening equipment technology, and more particularly to a continuous sorting device for potatoes. Background Technology

[0002] Currently, potato screening in the market mainly relies on rotating variable-diameter screens, which screen potatoes according to their external dimensions. However, this method cannot effectively identify potatoes with damaged skin or lower weight, resulting in poor screening performance and affecting the market value of potatoes. Utility Model Content

[0003] The problem this application aims to solve is that existing variable diameter sieves for potatoes can only sieve potatoes based on their external size, and cannot distinguish the skin and weight of potatoes, thus easily resulting in the inclusion of inferior quality potatoes.

[0004] To address the aforementioned technical problems, this application provides a continuous sorting device for potatoes, including a frame. An image-capturing component is mounted on the upper part of the frame to photograph the surface condition of potatoes during transport, using image recognition technology to distinguish potatoes with damaged skin. A weighing component is arranged on one side of the image-capturing component to weigh the photographed potatoes, using a set weight threshold to distinguish potatoes with insufficient weight. A sliding conveyor component is arranged on one side of the weighing conveyor component to transport potatoes with intact skin and acceptable weight. A straight groove for material drop is formed between the weighing conveyor component and the sliding conveyor component on the upper part of the frame. The sliding conveyor component can reciprocate on the upper part of the frame to change the distance between itself and the weighing conveyor component, so that potatoes with damaged skin and insufficient weight fall along the straight groove.

[0005] Because the continuous sorting device of this application is designed with a photo conveying component, a weighing conveying component, and a sliding conveying component, it can automatically detect and classify the surface condition and weight of potatoes by using image recognition technology and weight detection technology. This solves the problem that the existing variable diameter sieve cylinder for potatoes can only screen according to the size of the potatoes and cannot distinguish the surface condition and weight of the potatoes, thus easily mixing in potatoes of poor quality.

[0013] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example

[0014] This application relates to a continuous sorting device for potatoes, such as... Figure 1-6As shown, the sorting device includes a platform 5, with casters 4 around its lower perimeter for easy movement and positioning. The upper part of the platform 5 is sequentially equipped with a photographing conveyor assembly 1, a weighing conveyor assembly 2, and a sliding conveyor assembly 3. The photographing conveyor assembly 1 photographs the surface condition of the potatoes during transport, using image recognition technology to distinguish potatoes with damaged skin. The weighing conveyor assembly 2 weighs the photographed potatoes, using a set weight threshold to distinguish potatoes with insufficient weight. The sliding conveyor assembly 3 transports potatoes with intact skin and acceptable weight. The sliding conveyor assembly 3 can reciprocate on the platform 5 to change its distance from the weighing conveyor assembly 2. When a potato with damaged skin or insufficient weight is detected, the sliding conveyor assembly 3 moves away from the weighing conveyor assembly 2. The directional movement causes unqualified potatoes to fall along the straight groove 6. When qualified potatoes are detected, the sliding conveyor component 3 moves towards the weighing conveyor component 2, conveying the qualified potatoes to the next process. A straight groove 6 for material dropping is formed between the weighing conveyor component 2 and the sliding conveyor component 3 on the upper part of the frame 5, allowing potatoes with damaged skin and low weight to fall along the straight groove 6, thus automatically removing unqualified potatoes. By arranging the photographing conveyor component 1, weighing conveyor component 2, and sliding conveyor component 3 in a row on the upper part of the frame 5, continuous conveying, automatic detection, and classification of potatoes are achieved, improving the efficiency and accuracy of potato screening. At the same time, the reciprocating motion of the sliding conveyor component 3 effectively separates qualified and unqualified potatoes, simplifying the subsequent processing procedures.

[0015] The camera conveying assembly 1 includes a first frame 8, a first conveyor belt 7, uprights 9, a horizontal plate 10, and a camera 11. The first frame 8 is arranged on the upper part of the platform 5 and along its length. The first frame 8 has sufficient strength and stability to support all components of the camera conveying assembly 1, ensuring the smooth operation of the conveyor belt and the stable installation of the camera 11. The first conveyor belt 7 is located on the upper part of the first frame 8 and serves to convey potatoes. The conveyor belt is made of wear-resistant material and has sufficient strength and durability to withstand the weight and friction of the potatoes. The conveyor belt runs continuously at a certain speed, conveying potatoes from the feed end to the discharge end, while ensuring that the potatoes maintain a stable position and posture during the conveying process. A vertically arranged upright 9 is arranged on one side of the first conveyor belt 7. The upright 9 supports and fixes the horizontal plate 10, ensuring that it is stably suspended above the first conveyor belt 7. The height and position of the upright 9 are precisely adjusted to ensure that the camera 11 can accurately aim at the potatoes on the conveyor belt for taking pictures. The horizontal plate 10... The horizontal plate 10 is positioned horizontally above the upright 9, providing a suspended support. It possesses sufficient rigidity and stability to support the weight of the camera 11 and prevent it from swaying or shifting during operation. The length and width of the horizontal plate 10 are designed according to the size and installation requirements of the camera 11, ensuring that the camera 11 can be securely mounted on it. The camera 11 is vertically positioned at the end of the horizontal plate 10, illuminating the potatoes on the upper part of the first conveyor belt 7. The camera 11 has high resolution and fast shooting capabilities, clearly capturing the details of the potato skin. It continuously photographs the potatoes on the conveyor belt, transmitting the image data to the control system for subsequent processing and analysis. After receiving the images captured by the camera 11, the control system uses image recognition technology to identify the condition of the potato skin. By comparing and analyzing the feature information in the images, such as color, texture, and shape, the control system can accurately identify potatoes with damaged skin. Once a damaged potato is detected, the control system will issue a command to trigger subsequent classification and rejection operations.

[0016] The weighing and conveying assembly 2 includes a second frame 13, a second conveyor belt 12, a bracket 14, and a weighing sensor 15. The second frame 13 is arranged on the upper part of the platform 5 and is connected end-to-end with the first frame 8 along its length. The second frame 13 is made of high-strength material, has good load-bearing capacity and stability, and can ensure that no deformation or vibration occurs during potato conveying, thereby ensuring weighing accuracy. The second conveyor belt 12 is supported on the upper part of the second frame 13 and plays the role of conveying potatoes. The second conveyor belt 12 is made of wear-resistant and anti-slip material, which can ensure that potatoes do not slip or break during conveying. At the same time, the running speed of the second conveyor belt 12 is adjustable to suit various conditions. To meet different processing needs, the bracket 14 is arranged on the upper part of the platform 5 and serves as a suspended support. The bracket 14 is made of lightweight materials to reduce the impact of its own weight on the weighing accuracy. The structural design of the bracket 14 is reasonable, which can ensure that while supporting the second frame 13, it does not affect the normal operation of the second conveyor belt 12. The weighing sensor 15 is arranged on the upper part of the bracket 14 and abuts against the second frame 13. The weighing sensor 15 adopts high-precision sensor technology and can detect the weight of the second frame 13 and the potatoes supported on it in real time and accurately. The weighing sensor 15 is connected to the control system and can transmit the detected weight data to the control system in real time for processing and analysis.

[0017] The sliding conveyor assembly 3 includes a third frame 17, a third conveyor belt 16, a screw sleeve 21, a screw 20, a motor 22, guide rods 18, and a slider 19. The third frame 17 is arranged on the upper part of the platform 5 and is connected end-to-end with the second frame 13 along its length. The third frame 17 adopts a robust frame structure design to ensure the stability and load-bearing capacity of the conveying process. The third conveyor belt 16 is supported on the upper part of the third frame 17 and is responsible for conveying potatoes. The third conveyor belt 16 is made of wear-resistant material and has a long service life. At the same time, its surface is designed with anti-slip texture to ensure that potatoes will not slip during the conveying process. To improve the stability of the reciprocating motion of the third frame 17 and the third conveyor belt 16 along the surface of the platform 5, guide rods 18 are symmetrically arranged on both sides of the screw 20. The guide rods 18 are made of high-strength material and have excellent straightness and wear resistance, which can effectively guide the sliding of the third frame 17. The lower part of the third frame 17 is equipped with a slider 19 that slides and engages with the guide rod 18. The slider 19 has a sliding cavity that matches the guide rod 18, reducing frictional resistance during sliding and making the movement of the third frame 17 smoother. A threaded sleeve 21 is arranged at the middle of the bottom length of the third frame 17 and is connected to it. A screw 20 is arranged on the upper part of the platform 5 along the length of the bottom of the third frame 17 and is engaged with the threaded sleeve 21. When the screw 20 rotates, the engagement between the threaded sleeve 21 and the screw 20 drives the third frame 17 to reciprocate along the surface of the platform 5. A motor 22 is arranged at one end of the screw 20 and is connected to it and can drive it to rotate. The motor 22 is connected to the screw 20 through a transmission device and provides power for the rotation of the screw 20. By controlling the forward and reverse rotation and the speed of the motor 22, the movement direction and speed of the third frame 17 can be precisely controlled.

[0018] During use, first ensure the power connection of the entire device is normal. Then, follow the prompts of the control system to start each component step by step. On the control system interface, set the relevant parameters of the photo-conveying conveyor component 1, the weighing conveyor component 2, and the sliding conveyor component 3 according to production needs. For example, set the running speed of the conveyor belt, the frequency and resolution of the photo taking, and the weighing accuracy. Place the potatoes to be processed at the feed end of the photo-conveying conveyor component 1. As the first conveyor belt 7 runs, the camera 11 will automatically take a picture of each potato passing by. The control system receives and processes these images, and uses image recognition technology to detect the surface condition of the potatoes, identifying damaged or unqualified potatoes. Potatoes that have been photographed and identified will be transferred to the weighing conveyor component 2. As the second conveyor belt 12 runs, the weighing sensor 15 will automatically record the weight of each potato. The control system will receive and record this weight data in real time. The potatoes are sorted according to a preset weight range. Based on the results of photography and weighing, the control system sends instructions to the sliding conveyor assembly 3 to classify and transport the potatoes to different locations. Qualified potatoes are transported to a designated qualified product area, while unqualified potatoes, such as damaged or underweight potatoes, are transported to another designated unqualified product area. The position and speed of the sliding conveyor assembly 3 can be adjusted in real time according to production needs to ensure that the potatoes are accurately and efficiently classified and transported. Operators can monitor the entire sorting process in real time through the control system interface, including the potato transport status, photography and weighing results, etc. The system will automatically record all operation data, including the image, weight and classification result of each potato. This data can be used for subsequent quality analysis and production optimization. If the device malfunctions or is abnormal, the control system will issue an early warning in a timely manner and guide the operator to take appropriate action.
