Description

Technical Field

[0001] This utility model relates to the field of seed screening technology, specifically to a gravity-based seed selection device. Background Technology

[0002] As the most basic production material in agricultural production, the quality of seeds directly determines the final yield and product quality of crops. In the seed processing process, selection is a crucial step. Through professional gravity-based selection equipment, seeds can be effectively graded and screened, and unqualified seeds can be removed, thereby obtaining high-quality seeds with higher purity and stronger vigor.

[0003] Currently, most traditional seed-selecting equipment on the market is mainly limited to separating light debris (such as glumes and stem fragments) and some granular impurities (such as mud and stones) mixed in with seeds.

[0004] However, these devices have limitations. They generally lack an effective particle size classification mechanism and cannot perform precise vibration separation based on the physical size of the seed particles, resulting in poor uniformity of the screened seeds.

[0005] Furthermore, during the cleaning process, the equipment often overlooks the fine dust adhering to the seed surface and lacks effective dust removal methods. This residual dust not only affects the appearance of the seeds but also absorbs moisture during storage, which may cause the seeds to become damp or even moldy.

[0006] Based on this, the present invention provides a gravity-based seed selection device to solve the above problems. Utility Model Content

[0007] In view of the above situation and to overcome the defects of the prior art, this utility model provides a gravity-based seed sorting device. This utility model has a novel structure and ingenious design, and effectively solves the technical problems of seeds being unable to be sorted and the dust carried by the seeds being unprocessable.

[0008] A gravity-based seed sorting device includes a lower housing and an adjusting housing. The adjusting housing is fixedly connected to the top of the lower housing. A swaying lower support frame is installed inside the adjusting housing. A screen enclosure is installed on the top of the lower support frame. A sorting screen is fixedly connected to the screen enclosure. An air distribution plate is fixedly connected to the bottom of the screen enclosure. The air distribution plate is located between the sorting screen and the lower support frame. A rear feed port is opened on one side of the screen enclosure. Multiple rear adjusting plates are rotatably connected to the bottom of the rear feed port. A side feed port is opened on the other side of the screen enclosure. Multiple side adjusting plates are rotatably connected to the bottom of the side feed port.

[0009] Preferably, a vibration balancing component is provided inside the adjustment box. One side of the vibration balancing component is rotatably connected to one side of the inner wall of the adjustment box. A cylinder is fixedly connected to one side of the inner wall of the lower box. The output end of the cylinder is fixedly connected to the bottom of the other side of the vibration balancing component. Multiple vibration rockers are rotatably connected to the top of the vibration balancing component. The top ends of the multiple vibration rockers are rotatably connected to the bottom of the lower support frame.

[0010] Preferably, a three-phase asynchronous motor and a bearing housing are fixedly connected to the top of the vibration balancing component. A rotating shaft is fixedly connected to the output end of the three-phase asynchronous motor. The rotating shaft is rotatably connected to the bearing housing. A frame cam is fixedly connected to the rotating shaft. A cam guide rod is fixedly connected to one side of the frame cam. The other end of the cam guide rod is rotatably connected to the bottom of the lower support frame.

[0011] Preferably, the adjustment box is provided with a longitudinal adjustment frame and a transverse adjustment frame, the longitudinal adjustment frame is located below the vibration balancer, and the transverse adjustment frame is located between the vibration balancer and the three-phase asynchronous motor.

[0012] Preferably, a rear hopper is fixedly connected to one side of the lower housing, the rear hopper being located below the rear guide port and cooperating with the rear guide port; a side hopper is fixedly connected to the other side of the lower housing, the side hopper being located below the side guide port and cooperating with the side guide port.

[0015] The present invention has the following technical effects.

[0016] 1. This utility model uses a three-phase asynchronous motor, frame cam, cam guide rod, and vibrating rocker arm to convert rotational motion into vibration of the sorting screen surface. This not only allows the seeds to be evenly distributed and flow forward on the screen surface, but also enables them to be divided according to their specific gravity and particle size, effectively improving the sorting accuracy. By setting a rear guide port and a side guide port, it is convenient to discharge the sorted seeds. The rear adjustment plate and the side adjustment plate can be flexibly adjusted to precisely control the discharge speed and flow rate, greatly facilitating the classification of seeds of different grades.

Detailed Implementation

[0025] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 5 The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.

[0026] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0027] This invention relates to a gravity-based seed selection device. Existing selection devices generally lack an effective particle size classification mechanism, making it difficult to achieve precise separation based on seed physical size, resulting in poor uniformity of the finished product.

[0028] Furthermore, its dust removal methods are insufficient, failing to effectively remove dust adhering to the seed surface, which not only affects the appearance and marketability but also creates a risk of moisture absorption and mold growth during subsequent storage.

[0029] As an example, such as Figure 1 and Figure 2 The present invention includes a lower housing 1 and an adjusting housing 2. The adjusting housing 2 is fixedly connected to the top of the lower housing 1. A swaying lower support frame 6 is provided inside the adjusting housing 2. A screen enclosure 14 is provided on the top of the lower support frame 6. A sorting screen 15 is fixedly connected to the screen enclosure 14. An air distribution plate 7 is fixedly connected to the bottom of the screen enclosure 14. The air distribution plate 7 is located between the sorting screen 15 and the lower support frame 6. A rear guide port 16 is opened on one side of the screen enclosure 14. Multiple rear adjusting plates 17 are rotatably connected to the bottom of the rear guide port 16. A side guide port 19 is opened on the other side of the screen enclosure 14. Multiple side adjusting plates 20 are rotatably connected to the bottom of the side guide port 19.

[0030] In this embodiment, by driving the lower support frame 6 to shake regularly, the screen enclosure 14 connected to it and the sorting screen 15 fixed thereon will vibrate synchronously, causing the seeds on the sorting screen 15 to form a uniform distribution and directional flow, thereby achieving automatic sorting based on particle size and specific gravity differences. The sorted seeds are discharged through the rear guide port 16 and the side guide port 19, which is convenient for workers to classify and collect. By adjusting the opening angle of the rear adjustment plate 17 and the side adjustment plate 20, the flow rate and speed of each discharge port can be flexibly controlled, thereby adapting to the processing needs of different seeds and improving the convenience of operation and processing efficiency.

[0031] As an example, such as Figure 2 The adjustment box 2 is equipped with a vibration balancing component 4. One side of the vibration balancing component 4 is rotatably connected to one side of the inner wall of the adjustment box 2. A cylinder 30 is fixedly connected to one side of the inner wall of the lower box 1. The output end of the cylinder 30 is fixedly connected to the bottom of the other side of the vibration balancing component 4. Multiple vibration rocker arms 5 are rotatably connected to the top of the vibration balancing component 4. The top ends of the multiple vibration rocker arms 5 are rotatably connected to the bottom of the lower support frame 6.

[0032] As an example, such as Figure 2A three-phase asynchronous motor 9 and a bearing seat 11 are fixedly connected to the top of the vibration balancing component 4. A rotating shaft 10 is fixedly connected to the output end of the three-phase asynchronous motor 9. The rotating shaft 10 is rotatably connected to the bearing seat 11. A frame cam 12 is fixedly connected to the rotating shaft 10. A cam guide rod 13 is fixedly connected to one side of the frame cam 12. The other end of the cam guide rod 13 is rotatably connected to the bottom of the lower support frame 6.

[0033] As an example, such as Figure 2 The adjustment box 2 is equipped with a longitudinal adjustment frame 3 and a transverse adjustment frame 8. The longitudinal adjustment frame 3 is located below the vibration balance component 4, and the transverse adjustment frame 8 is located between the lower support frame 6 and the three-phase asynchronous motor 9.

[0034] In this embodiment, the three-phase asynchronous motor 9 drives the rotating shaft 10 to rotate stably on the bearing seat 11, thereby driving the frame cam 12 fixed on the rotating shaft 10 to perform circular motion. The frame cam 12 drives the cam guide rod 13 connected to it through its inner contour. The cam guide rod 13 continuously pushes the lower support frame 6, causing it to vibrate regularly, and finally transmits the vibration to the sorting screen surface 15, forming an effective sieving motion to achieve seed diversion. During the vibration of the lower support frame 6, the top of the vibrating rocker arm 5 rotates with the lower support frame 6, and the bottom rotates with the vibration balance component 4, forming a stable swing support. This not only effectively transmits the vibration to the sorting screen surface 15, ensuring that the sorting screen surface 15 runs more smoothly during the vibration screening process, but also, through the operation of the cylinder 30, pushes the vibration balance component 4 to rotate in the adjustment box 2, thereby adjusting the angle of the upper sorting screen surface 15 for use with seeds of different particle sizes.

[0035] As an example, such as Figure 4 A rear hopper 18 is fixedly connected to one side of the lower box 1. The rear hopper 18 is located below the rear guide port 16 and cooperates with the rear guide port 16. A side hopper 21 is fixedly connected to the other side of the lower box 1. The side hopper 21 is located below the side guide port 19 and cooperates with the side guide port 19.

[0036] In this embodiment, a portion of the seeds after diversion is discharged through the rear feed port 16 and falls into the rear hopper 18, while another portion of the seeds is discharged through the side feed port 19 and falls into the side hopper 21, thereby collecting the sorted seeds and facilitating subsequent processing by the staff.

[0037] As an example, such as Figure 2 and Figure 3 An air inlet 26 is provided on one side of the lower housing 1. A fan silencer 27 is installed inside the air inlet 26. An exhaust fan 28 is fixedly connected inside the lower housing 1. The exhaust fan 28 works in conjunction with the air inlet 26.

[0038] As an example, such as Figure 4 A fixed frame 22 is fixedly connected to the top of the regulating box 2, and a wind hood 23 is fixedly connected to the fixed frame 22. A sealing structure is provided between the wind hood 23 and the regulating box 2, so that the lower box 1 and the regulating box 2 are in a sealed state. The wind hood 23 is located above the sorting screen surface 15. An air outlet 24 and a feed inlet 25 are opened on the top of the wind hood 23. Another exhaust fan is set on the top of the wind hood 23 to exhaust air from the inside of the wind hood 23. Multiple inspection ports 29 are provided on the lower box 1.

[0039] In this embodiment, seeds to be sorted are placed into the feed inlet 25 and fall onto the sorting screen 15. The exhaust fan 28 operates to draw external air into the lower chamber 1 through the air inlet 26. When the exhaust fan 28 is running, the fan silencer 27 set at the air inlet 26 can effectively reduce operating noise and improve the working environment. The airflow drawn in forms a stable upward flow in the lower chamber 1, and after evenly penetrating the air distribution plate 7, it acts on the sorting screen 15. Thus, while the seeds are vibrating and sorting, the dust carried in them is blown away and cleaned. The dust-laden airflow then enters the upper hood 23, and the exhaust fan connected to the air outlet 24 on the hood 23 continuously draws out the dust-laden gas, thereby achieving continuous dust removal.

[0040] Working principle of this utility model:

[0041] Workers feed the seeds to be sorted into the feed inlet 25 on the fan hood 23. The seeds then scatter onto the sorting screen 15. At this time, the three-phase asynchronous motor 9 starts and drives the rotating shaft 10 to rotate. Through the cooperation of the frame cam 12 and the cam guide rod 13, the rotational motion is converted into regular mechanical vibration and transmitted to the entire sorting screen 15. Under the continuous vibration, the seeds form a uniform thin layer on the screen and are efficiently separated according to the differences in particle size and specific gravity. The sorted seeds are discharged from the rear feed inlet 16 and the side feed inlet 19 respectively and fall accurately into the corresponding rear hopper 18 and side hopper 21, thus completing the classification and collection of seeds of different grades, which is convenient for workers to operate uniformly.

[0042] During the screening process, the exhaust fan 28 is started simultaneously, continuously drawing outside air into the lower chamber 1. The airflow evenly penetrates the air distribution plate 7 from bottom to top in the lower chamber 1, continuously blowing on the seeds on the sorting screen 15, effectively removing light impurities and dust attached to their surface. The dust-laden airflow enters the upper hood 23 under negative pressure, and is finally concentratedly extracted by the exhaust fan set at the air outlet 24 at the top of the hood 23, realizing the simultaneous operation of sorting and dust removal, and ensuring the operation of the equipment.

[0043] The present invention has the following technical effects.

[0044] 1. This utility model uses a three-phase asynchronous motor 9, a frame cam 12, a cam guide rod 13, and a vibrating rocker arm 5 to convert rotational motion into vibration of the sorting screen surface 15. This not only allows the seeds to be evenly distributed and flow forward on the screen surface, but also enables them to be divided according to their specific gravity and particle size, effectively improving the sorting accuracy. By setting a rear guide port 16 and a side guide port 19, it is convenient to discharge the sorted seeds. The rear adjustment plate 17 and the side adjustment plate 20 can be flexibly adjusted to precisely control the discharge speed and flow rate, greatly facilitating the classification of seeds of different grades.

[0045] 2. This utility model uses an air inlet 26, a fan silencer 27, and an exhaust fan 28 to create an upward airflow inside the regulating box 2, which acts on the entire sorting screen 15. While the seeds are being vibrated and sorted, the airflow effectively removes and eliminates light dust and impurities. The dust is then discharged through the air outlet 24 on the air hood 23, achieving simultaneous sorting and dust removal, and significantly improving the final cleanliness of the seeds.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
