Description

Technical Field

[0001] This utility model relates to the field of rapeseed cleaning technology, specifically a rapeseed cleaning and filtration device. Background Technology

[0002] In the rapeseed planting industry, the quality of rapeseed seeds has a crucial impact on subsequent sowing results, crop growth, and final yield. However, throughout the entire process from harvest to sowing, rapeseed seeds are often mixed with various impurities, including stones and straw fragments larger than the diameter of the rapeseed seeds, as well as dust and fine sand particles smaller than the diameter of the rapeseed seeds.

[0003] Traditional rapeseed seed cleaning and filtration methods mostly rely on manual screening, which is not only inefficient and wasteful of manpower and resources, but also difficult to guarantee in terms of screening effectiveness. It fails to completely separate impurities of different sizes from the rapeseed seeds, resulting in low seed purity at sowing and consequently affecting the germination rate and growth quality of the rapeseed. With the development of agricultural modernization, higher demands are placed on the efficiency and effectiveness of rapeseed seed cleaning and filtration. Therefore, the development of a high-efficiency and reliable rapeseed seed cleaning and filtration device is urgently needed. Utility Model Content

[0023] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the embodiments without creative effort are all within the protection scope of this utility model.

[0024] Example 1: Reference Figures 1-5The rapeseed cleaning and filtering device shown includes a screening mechanism mounted on a support frame 1. The screening mechanism includes a first screening component, a second screening component, and a collection component, which are sequentially and inclinedly mounted on the support frame 1 from top to bottom; a vibration component mounted on the support frame 1 and controlling the synchronous vibration of the first screening component, the second screening component, and the collection component; a feeding component mounted on the support frame 1 and pouring rapeseed seeds onto the high end of the first screening component; and a storage component mounted on the support frame 1 and located at the low ends of the first screening component, the second screening component, and the collection component, respectively.

[0025] The first screening component is used to screen out impurities larger than the diameter of rapeseed seeds; the second screening component is used to screen out rapeseed seeds; and the collection component is used to collect impurities smaller than the diameter of rapeseed seeds.

[0026] In this embodiment, the feeding assembly includes a feeding bin 2 disposed on the support frame 1 and a guide tube 3 disposed at the bottom of the feeding bin 2. The guide tube 3 guides the rapeseed seeds in the feeding bin 2 to the high end of the first screening assembly.

[0027] like Figures 1-5As shown, in this embodiment, the operator pours the rapeseed seeds to be cleaned and filtered through the feeding assembly to the high end of the first screening assembly. The feeding assembly uses a feeding hopper 2, and the seeds are poured onto the high end of the first screening assembly through the guide pipe 3 set on the feeding hopper 2, ensuring that the rapeseed seeds can smoothly and evenly enter the screening process. After the rapeseed seeds enter the first screening assembly, since the first screening assembly is set at an incline, the seeds and impurities will move towards the lower end along the inclined surface of the first screening assembly under the action of its own gravity and the vibration assembly. The first screening assembly uses its specific structure (with screening rods with a spacing greater than the diameter of the rapeseed) to screen out impurities larger than the diameter of the rapeseed, including larger stones, straw, etc. These impurities will be blocked on the first screening assembly, while the rapeseed seeds and smaller impurities continue to move downwards. After the initial screening, the rapeseed seeds and smaller impurities enter the second screening assembly. Similarly, under the action of inclination and vibration, they move towards the lower end of the second screening assembly. The structure of the second screening component (equipped with screening rods spaced smaller than the diameter of the rapeseed seeds) ensures that only rapeseed seeds remain on the second screening component, while impurities smaller than the rapeseed seed diameter, such as dust and fine sand, pass through and fall onto the collection component. The rapeseed seeds retained in the second screening component continue to move downwards into the storage component. The collection component is also tilted, and dust and fine sand, under the influence of the vibrating component and gravity, move to its lower end and enter the storage component located there. Meanwhile, the impurities and rapeseed seeds retained on the first and second screening components also move to their respective lower ends and enter their corresponding storage components, completing the entire cleaning and filtration process. This process achieves efficient and precise cleaning and filtration of rapeseed seeds, greatly improving seed quality and subsequent sowing results, while also saving labor and time costs, demonstrating significant advantages over traditional screening methods.

[0028] In this embodiment, traditional manual or simple mechanical screening methods are slow and require a significant amount of time and manpower. Manual screening is prone to fatigue, leading to unstable screening speeds; simple mechanical screening may not achieve a continuous and efficient screening process. This equipment, through the cooperation of multi-stage screening components and vibration components, achieves continuous and automated screening of rapeseed seeds. The equipment can quickly separate rapeseed seeds from impurities of different sizes, greatly improving screening efficiency and processing large quantities of rapeseed seeds in a short time, meeting the needs of large-scale agricultural production. Furthermore, the first and second screening components respectively screen impurities of different sizes, and the reasonable spacing of the screening rods can accurately separate impurities larger than and smaller than the diameter of the rapeseed seeds, ensuring high purity of the screened rapeseed seeds and providing high-quality seeds for subsequent sowing and crop growth.

[0029] Three support bars 4 are arranged obliquely from top to bottom on the support frame 1. The support bars 4 are U-shaped and the opening is located on the side away from the feeding component. The first screening component, the second screening component and the collecting component are respectively arranged in the three support bars 4 from top to bottom.

[0030] The first screening component includes a first screening plate 5 that is inclinedly disposed within a support bar 4, a rotating rod 22 disposed on the bottom side of the opening position of the support bar 4 and rotatably connected to the lower end of the first screening plate 5 in the middle of the rod body, and multiple first screening rods 6 arranged at equal intervals within the openings on the end face of the first screening plate 5. The length direction of the first screening rods 6 is along the length direction of the first screening plate 5, and the distance between adjacent first screening rods 6 is greater than the diameter of the rapeseed.

[0031] like Figures 1-5 As shown, when the mixture of rapeseed seeds and impurities enters from the feeding assembly and falls onto the inclined first screening plate 5, under its own gravity and the action of the subsequent vibration assembly, the seeds and impurities move towards the lower end along the first screening plate 5. Since the distance between adjacent first screening rods 6 is greater than the diameter of the rapeseed seeds, impurities larger than the rapeseed seeds, such as larger stones and thick straw, will be blocked between the first screening rods 6 and cannot pass through. This achieves preliminary screening of impurities larger than the rapeseed seed diameter, laying the foundation for further screening. The rotating rod 22 allows the first screening plate 5 to vibrate stably under the action of the vibration assembly, enhancing the screening effect.

[0032] The second screening component includes a second screening plate 7 inclinedly disposed within the support bar 4, a rotating rod 22 disposed on the bottom side of the opening position of the support bar 4 and rotatably connected to the lower end of the second screening plate 7 in the middle of the rod body, and multiple second screening rods 8 arranged at equal intervals in the openings on the end face of the second screening plate 7. The length direction of the second screening rods 8 is arranged along the length direction of the second screening plate 7, and the distance between adjacent second screening rods 8 is less than the diameter of the rapeseed. The second screening plate 7 is located parallel to the bottom of the first screening plate 5.

[0033] like Figures 1-4 As shown, in this embodiment, the rapeseed seeds and any remaining smaller impurities after initial screening by the first screening component fall onto the second screening plate 7. Under their own weight and the action of the vibration component, they move towards the lower end of the second screening plate 7. Because the distance between adjacent second screening rods 8 is smaller than the diameter of the rapeseed seeds, only the rapeseed seeds remain on the second screening rods 8 and move along the inclined direction. Impurities smaller than the rapeseed seed diameter, such as dust and fine sand, fall through the gaps between adjacent second screening rods 8 onto the collection plate 9, thus achieving precise screening of the rapeseed seeds and further improving seed purity. The rotating rod 22 ensures the stability of the second screening plate 7 during vibration, ensuring the smooth progress of the screening process.

[0034] The collection assembly includes a collection plate 9 that is inclinedly disposed within the support bar 4, and a rotating rod 22 disposed on the bottom side of the opening of the support bar 4 and rotatably connected to the lower end of the collection plate 9 in the middle of the rod body. The collection plate 9 is located parallel to the lower part of the second screening plate 7.

[0035] like Figures 1-4 As shown in this embodiment, after the rapeseed seeds are screened through the second screening component, dust, fine sand particles, etc., fall onto the collection plate 9. Under the action of its own gravity and the vibration component, the dust, fine sand particles, etc., move along the collection plate 9 towards the lower end, and finally enter the storage component located at the lower end of the collection plate 9, completing the collection of dust and fine sand particles after cleaning and filtration. The rotating rod 22 also helps the collection plate 9 to remain stable during vibration, ensuring that the seeds can move smoothly into the storage component.

[0036] like Figures 1-5 As shown, the rapeseed seed diameter is typically between 1.5 mm and 2.4 mm. To ensure clean filtration of the rapeseed seeds, in this embodiment, the gap between adjacent first screening rods 6 is greater than 2.4 mm, and the gap between adjacent second screening rods 8 is less than 1.5 mm.

[0037] The vibration assembly includes three horizontal bars 11 arranged laterally on the support frame 1 and located on one side of the high end of the three support bars 4; three vertical sliding bars 14 that pass through the middle of the horizontal bars 11 and have limiting slots 12 opened in the length direction; sliders 21 that are rotatably arranged on the bottom side of the high end of the three support bars 4 and are slidably sleeved on the different sliding bars 14; and a vibration element arranged on the support frame 1 and controlling the reciprocating movement of the three sliding bars 14 in the limiting slots 12.

[0038] like Figure 3 and Figure 4As shown, in this embodiment, when the slide bar 14 moves within the limiting slot 12, it works in conjunction with the slider 21 on the slide bar 14 to rotate the first screening plate 5, the second screening plate 7, and the collecting plate 9 around the rotating rod 22. This causes the first screening plate 5, the second screening plate 7, and the collecting plate 9 to swing and vibrate within the support bar 4, achieving synchronous vibration of the first screening plate 5, the second screening plate 7, and the collecting plate 9. The vibration component provides a support base through the crossbar 11, the limiting slot 12 restricts and guides the movement of the slide bar 14, the slide bar 14 transmits power, the slider 21 connects the slide bar 14 and the support bar 4 and realizes vibration conversion, and the vibration component provides power. All parts work together to achieve synchronous and stable vibration control of the three support bars 4 and the screening components on them. This vibration method allows the rapeseed seeds to fully tumble and move during the screening process, making full contact with the screening rod, improving the efficiency and accuracy of screening. It can effectively separate impurities of different sizes from the rapeseed seeds, greatly improving the screening effect and seed quality compared to screening methods that do not use vibration components or have unstable vibration.

[0039] The vibrating component includes a vertical rod 13 that is vertically arranged and connected to one end of three sliding rods 14; a limiting rod 15 that is mounted on the support frame 1 and located below the vertical rod 13; a connecting rod 17 that passes through the sliding groove 16 along the length of the limiting rod 15 and is fixedly connected to the bottom end of the vertical rod 13 at one end; and a drive motor 20 that is mounted on the support frame 1 and has a rotating disk 19 connected to its output end. A linkage rod 18 is rotatably connected between the eccentric position of the end face of the rotating disk 19 and the end of the connecting rod 17. The top side of the limiting rod 15 has a sliding groove 16 along its length.

[0040] like Figure 3 As shown, in this embodiment, the various parts of the vibrating component cooperate with each other. The drive motor 20 drives the rotating disk 19 to rotate. The rotating disk 19 drives the connecting rod 17 to reciprocate linearly within the slide groove 16 of the limiting rod 15 via the linkage rod 18. The connecting rod 17 then drives the vertical rod 13 to reciprocate. The vertical rod 13 further drives the three sliding rods 14 to reciprocate linearly within the limiting slot 12. Finally, the slider 21 drives the support bar 4 and the screening components on it to vibrate. This design allows the screening components to obtain stable and regular vibration, enabling the rapeseed seeds to fully tumble and move during the screening process, making full contact with the screening rod. This effectively improves the efficiency and accuracy of screening, and can accurately separate impurities of different sizes from the rapeseed seeds. Compared with traditional or unstable vibration screening methods, this greatly improves the screening effect and seed quality.

[0041] like Figures 1-4As shown in this embodiment, three guide plates 10 are provided on the support frame 1 below the openings of the three support bars 4, respectively, to guide the debris, rapeseed and fine sand particles screened on the first screening plate 5, the second screening plate 7 and the collection plate 9 into the corresponding storage components.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
