Description

Technical Field

[0001] This utility model belongs to the technical field of camellia seed collection equipment, specifically relating to a seed collection device. Background Technology

[0002] Camellia seeds typically require air drying to remove the pericarp before being crushed to extract the seeds. Currently, camellia seeds are collected manually, a method that is inefficient and physically demanding. Utility Model Content

[0003] This invention provides a seed collection device, which aims to solve the problems of low efficiency and high labor intensity of operators in the existing technology for collecting camellia seeds.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A seed collection device includes a conveying component, a pre-screening component for removing impurities and unqualified seeds, a sorting component for removing seeds with unqualified color, a drying component for drying the pericarp, a peeling component for crushing the pericarp, and a post-screening component for removing the pericarp. Camellia seeds screened by the pre-screening component pass sequentially through the sorting component, the drying component, and the peeling component via the conveying component and enter the post-screening component under gravity.

[0006] The peeling assembly includes a support frame, on which a pressing roller is mounted. The pressing roller is rotatably connected to the support frame. An elastic element is provided between the pressing roller and the support frame to prevent the pressing roller from applying excessive pressure to the seeds on the conveying assembly. The pressing roller is slidably connected to the support frame via a slide block, and the pressing roller and the slide block are rotatably connected. The slide block is slidably connected to the support frame.

[0007] A further improved solution: The bracket is provided with a guide groove for guiding the slide block, the slide block is slidably connected in the guide groove, the guide groove includes a top wall and a bottom wall opposite to the top wall, the elastic element is provided between the slide block and the top wall, and the elastic element is provided between the slide block and the bottom wall.

[0008] Based on the above technical solution: the sliding connection structure between the guide groove on the support and the slide, combined with the design of the elastic element, significantly improves the stability and adjustment flexibility of the device. Elastic elements are installed between the top and bottom walls of the guide groove and the slide, ensuring that the slide remains stable during movement and preventing displacement or jamming caused by external forces or vibrations. The buffering effect of the elastic element not only reduces frictional loss between the slide and the guide groove but also enhances the device's adaptability to different working conditions.

[0009] A further improved solution: the elastic element is a spring, and guide posts are provided on the top wall, the bottom wall and the slide, with the two ends of the elastic element respectively sleeved on the corresponding guide posts.

[0010] Based on the above technical solution: the elastic element adopts a spring design and is precisely positioned and fixed by guide posts on the top wall, bottom wall, and slide block, significantly improving the stability and adjustment accuracy of the device. The guide posts ensure that the spring maintains linear motion during compression or extension, avoiding uneven force distribution or jamming caused by offset or torsion. This structural design not only enhances the service life of the elastic element but also allows for more precise adjustment of the pressure of the fruit pressing roller, adapting to the processing needs of fruit peels of different thicknesses and hardnesses. Simultaneously, the optimized distribution of the guide posts improves the force transmission path, making the slide block more stable during movement, further enhancing the reliability and working efficiency of the device.

[0011] A further improved solution: A rubber sleeve is fitted on the side wall of the pressing roller that contacts the seed, the rubber sleeve is adhered to the pressing roller, and the rubber sleeve is patterned.

[0012] Based on the above technical solution, the rubber sleeve and its surface pattern design on the side wall of the fruit pressing roller significantly improve the practicality of the device and the seed protection effect. The elastic material of the rubber sleeve can buffer pressure, preventing mechanical damage when the fruit pressing roller directly contacts the seeds, while ensuring that the fruit peel is crushed evenly. The pattern on the rubber sleeve increases the friction with the fruit peel, preventing the peel from slipping during the crushing process and improving peeling efficiency. The adhesive fixing method ensures the stability and durability of the rubber sleeve, avoiding frequent replacements.

[0013] A further improved solution: There are at least two peeling components, and the at least two peeling components are distributed along the conveying direction of the conveying component.

[0014] Based on the above technical solution, the peeling components employ a design with at least two distributed along the conveying direction, significantly improving the efficiency and reliability of camellia seed peeling. The distribution of multiple peeling components ensures that the pericarp is gradually crushed at different stages, avoiding seed damage that might result from excessive pressure in a single step. Simultaneously, this distribution method can adapt to pericarps of varying dryness or thickness, improving the device's adaptability to different batches of raw materials. Through staged processing, the separation of seeds and pericarps is more thorough, further reducing the workload of subsequent screening components.

[0015] A further improved solution: The pre-screening component is a pre-electric screen, which is inclined and the lower end of the pre-electric screen is located above the conveying component. The material on the screen of the pre-electric screen enters the conveying component under the action of gravity.

[0016] Based on the above technical solution: the pre-stage electric screen adopts an inclined structural design, which significantly improves the initial screening efficiency of camellia seeds. Due to the inclined angle, seeds and impurities naturally separate under gravity during the screening process. The material remaining on the screen (i.e., seeds that meet the requirements) automatically slides down to the conveyor assembly, requiring no additional power and reducing energy consumption. At the same time, this design reduces manual intervention, ensuring the continuity and stability of the screening process. The inclination angle of the pre-stage electric screen can be flexibly adjusted according to the characteristics of different batches of raw materials, making it highly adaptable and effectively removing impurities and broken seeds, providing a high-quality raw material foundation for subsequent sorting, air-drying, and other processes.

[0017] A further improved solution: the subsequent screening component is a subsequent electric screen, the subsequent electric screen is inclined, and the higher end of the subsequent electric screen is located below the conveying component.

[0018] Based on the above technical solution, the post-stage electric sieve adopts an inclined structural design, which significantly improves the final separation efficiency of camellia seeds and pericarps. By positioning the higher end below the conveying component, the seeds and pericarps naturally separate under gravity during the sieving process. The lighter pericarps are removed, while the seeds pass smoothly through the sieve holes for collection. This design not only reduces power consumption but also ensures the continuity and smoothness of the sieving process. Furthermore, the inclination angle can be flexibly adjusted according to the characteristics of the seeds and pericarps to adapt to the processing needs of different batches of raw materials.

[0019] A further improved solution: The conveying assembly includes a frame, on which a drive shaft and a driven shaft are disposed, the drive shaft being driven by a motor, and the conveying assembly further includes a conveyor belt wound around the drive shaft and the driven shaft.

[0020] Based on the above technical solution, the conveyor assembly adopts a structure design with a drive shaft and a driven shaft working together on a conveyor belt, significantly improving the stability and efficiency of camellia seed transport. The motor-driven drive shaft drives the driven shaft synchronously through the conveyor belt, achieving continuous and uniform seed transport and avoiding the inefficiency of traditional manual handling. The rigid support of the frame ensures the stable operation of the conveyor belt, reducing the risk of vibration and deviation.

[0021] A further improved solution: The air-drying assembly includes a fan and a heater for heating the airflow output by the fan, the airflow output by the fan being heated by the heater and then blown onto the seeds on the conveying assembly.

[0022] Based on the above technical solution, the air-drying component, through the combined design of a fan and a heater, significantly improves the efficiency and uniformity of camellia seed air-drying. The airflow output by the fan, heated by the heater, forms a stable hot air that directly acts on the seeds on the conveying component, accelerating the evaporation of moisture from the pericarp while avoiding localized overheating or uneven drying. The heater's temperature control function adjusts the air temperature according to the characteristics of the seeds and pericarp, ensuring a gentle and efficient drying process and preventing seed damage due to high temperatures. This design not only shortens the air-drying time but also improves the consistency of seed quality, providing ideal conditions for the subsequent peeling process.

[0023] A further improved solution: The sorting component includes a spectrophotometer for detecting the color of seeds on the conveying component and a robotic arm for removing seeds on the conveyor belt whose color does not meet the requirements. The robotic arm removes the seeds on the conveying component that do not meet the requirements based on the data detected by the spectrophotometer.

[0024] Based on the above technical solution, the sorting component achieves high precision and automation in camellia seed color sorting through the collaborative work of a spectrophotometer and a robotic arm. The spectrophotometer can quickly and accurately detect seed color and transmit the data to the control system, ensuring that seeds with abnormal colors are efficiently identified. The robotic arm precisely locates and removes unsuitable seeds based on the detection results, avoiding the errors and inefficiencies of manual sorting. This automated sorting method not only significantly improves sorting efficiency but also ensures the consistency of seed quality, providing high-quality raw materials for subsequent processes.

[0025] The beneficial effects of this utility model are as follows:

[0026] This utility model proposes a camellia seed collection device that integrates a conveying component, a pre-screening component, a sorting component, an air-drying component, a peeling component, and a post-screening component, achieving an automated process from seed collection to preliminary processing. First, the pre-screening component efficiently removes impurities and unsuitable seeds, ensuring the quality of seeds entering subsequent processes. The sorting component further eliminates seeds with abnormal colors using color recognition technology, improving the overall seed quality. The air-drying component simulates natural air-drying, ensuring uniform drying of the pericarp and facilitating subsequent peeling. The peeling component employs a pressing roller design, with pressure adjusted by elastic elements to avoid damaging the seeds while ensuring effective crushing of the pericarp. Finally, the post-screening component further separates the pericarp from the seeds, completing the entire collection process.

[0027] This device significantly improves the efficiency of camellia seed collection and reduces the labor intensity of manual operations. Through automated processes, it minimizes errors caused by human intervention, ensuring seed purity and consistency. Furthermore, its modular design allows it to adapt to production needs of varying scales, making it highly practical and worthy of widespread application. Overall, this device not only solves the problem of inefficiency in traditional manual collection methods but also improves the standardization of seed processing, providing technical support for the large-scale production of camellia seeds.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model. All other embodiments obtained by users of the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0035] refer to Figures 1 to 3 A seed collection device includes a conveying component 1, a pre-screening component 2 for removing impurities and unqualified seeds, a sorting component 3 for removing seeds with unqualified color, a drying component 4 for air-drying the pericarp, a peeling component 5 for crushing the pericarp, and a post-screening component 6 for removing the pericarp. Camellia seeds screened by the pre-screening component 2 pass sequentially through the sorting component 3, the drying component 4, and the peeling component 5 via the conveying component 1 and enter the post-screening component 6 under gravity.

[0036] The peeling assembly 5 includes a bracket 7, on which a pressing roller 8 is mounted. The pressing roller 8 is rotatably connected to the bracket 7. An elastic element 9 is provided between the pressing roller 8 and the bracket 7 to prevent the pressing roller 8 from applying excessive pressure to the seeds on the conveying assembly 1. The pressing roller 8 is slidably connected to the bracket 7 via a slide block 10. The pressing roller 8 and the slide block 10 are rotatably connected, and the slide block 10 is slidably connected to the bracket 7.

[0037] The bracket 7 is provided with a guide groove 11 to guide the slide 10. The slide 10 is slidably connected within the guide groove 11. The guide groove 11 includes a top wall and a bottom wall opposite to the top wall. An elastic element 9 is provided between the slide 10 and the top wall, and between the slide 10 and the bottom wall. The elastic element 9 is a spring. Guide posts are provided on the top wall, the bottom wall, and the slide 10. The two ends of the elastic element 9 are respectively sleeved on the corresponding guide posts. A rubber sleeve is provided on the side wall of the pressing roller 8 that contacts the seed. The rubber sleeve is adhered to the pressing roller 8 and has a pattern. There are at least two peeling components 5, which are distributed along the conveying direction of the conveying component 1. The pattern of the rubber sleeve can be designed as a multi-level anti-slip texture to enhance friction and reduce seed rolling damage. In addition, the two peeling components 5 are arranged in a stepped manner along the conveying direction. The front component pre-presses and breaks the peel, and the rear component deeply separates the peel, so as to achieve efficient processing in stages.

[0038] Specifically: The pre-stage screening component 2 is a pre-stage electric screen, which is inclined, with its lower end positioned above the conveying component 1. The material on the pre-stage electric screen enters the conveying component 1 under gravity. The post-stage screening component 6 is a post-stage electric screen, also inclined, with its higher end positioned below the conveying component 1. The conveying component 1 includes a frame with a drive shaft and a driven shaft mounted on it. The drive shaft is driven by a motor. The conveying component 1 also includes a conveyor belt wound around the drive shaft and the driven shaft. The air-drying component 4 includes a fan and a heater for heating the airflow output by the fan. The airflow output by the fan is heated by the heater and then blown onto the seeds on the conveying component 1. The sorting component 3 includes a spectrophotometer for detecting the color of the seeds on the conveying component 1 and a robotic arm for removing seeds from the conveying belt that do not meet the color requirements. The robotic arm removes the seeds from the conveying component 1 based on the data detected by the spectrophotometer.

[0039] A spectrophotometer is a high-precision optical detection device used for real-time analysis of the color characteristics of camellia seeds. Its workflow is as follows: The spectrophotometer has a built-in light source of a specific wavelength (such as an LED or xenon lamp) that evenly illuminates the seed surface on a conveyor belt. The light reflected from the seeds is received by the instrument's sensors and decomposed into different wavelengths of light by the spectrophotometer system. The system compares the collected spectral data with a preset standard color model (such as RGB or Lab values) and calculates the color difference (ΔE). If the color difference exceeds a set threshold, the seed is identified as having an abnormal color. The detection results are transmitted to the control system in real time, marking the location information of the abnormal seeds. A robotic arm, acting as the actuator, completes seed sorting based on the spectrophotometer data: the robotic arm, driven by a servo motor or pneumatics, precisely moves to the marked abnormal seed location on the conveyor belt. Flexible grippers or vacuum suction cups are used to grasp the seeds, avoiding damage to qualified seeds. After grasping, the robotic arm transfers the abnormal seeds to a waste collection tank or separates them by airflow. Some systems may be equipped with multi-stage sorting channels for further subdivision based on color differences. The robotic arm and conveyor belt are synchronized in speed, and encoder feedback ensures accurate timing of actions, avoiding missed detections or misoperations. A spectrophotometer and robotic arm form a closed-loop control system, completing the detection-execution cycle within milliseconds. The system can learn the color distribution of different batches of seeds, dynamically adjusting sorting thresholds to improve adaptability. Backup robotic arms or sorting channels are provided to ensure that a single point of failure does not affect overall efficiency.

[0040] The working principle of this embodiment:

[0041] First, the collected camellia fruit peels are evenly placed on the pre-screening unit 2. A vibrating screen removes impurities and damaged seeds, ensuring the quality of seeds entering subsequent processes. The screened seeds then enter the sorting unit 3, which automatically removes seeds with abnormal colors based on color recognition technology, retaining only those that meet the standards. Subsequently, the seeds enter the drying unit 4, where air circulation gradually dries the fruit peels, preparing them for the peeling process.

[0042] Adjust the pressure of the pressing roller 8 to ensure it effectively crushes the fruit peel without damaging the seeds. The elastic element 9 is designed for flexible adjustment based on the thickness and hardness of the fruit peel. The crushed fruit peel and seed mixture falls into the subsequent screening assembly 6 under gravity, where the peel and seeds are separated by the screen, ultimately collecting pure camellia seeds. Throughout the process, the operator only needs to monitor the equipment's operating status and adjust parameters as needed, without frequent manual intervention.

[0043] This utility model is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this utility model. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope of the claims of this utility model are within the protection scope of this utility model.
