Description

Technical Field

[0001] This utility model relates to the field of seed screening, and in particular to a drum-type seed screening device for research and development. Background Technology

[0002] Seed sieving equipment is a specialized machine used to grade and screen seeds according to size, shape, or specific gravity. It usually uses vibrating screens for grading and screening, separating seeds into different grades through screens with different apertures or airflow to ensure the uniformity and purity of seeds during the research and development process.

[0003] When screening seeds using planar vibration, the accumulated seeds need to be screened step by step, which is inefficient and ineffective. In addition, some soil will remain on the seed surface during the screening process, and it is extremely difficult to clean up the soil when it falls off directly. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rotary drum-type seed screening device for research and development, which improves the screening efficiency and the ease of cleaning up the soil and debris generated during screening.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A rotary drum-type seed screening device for research and development includes:

[0007] A bottom support plate for bottom support, with mounting blocks fixedly connected to both top sides of the bottom support plate, and a support sleeve fixedly connected to the top of the mounting blocks. A screening frame is set inside the support sleeve, and a mounting ring is fixedly connected to the right inner side of the support sleeve. The screening frame is rotatably connected to the inner side of the mounting ring. A drive motor is fixedly connected to the left side of the support sleeve, and a rotating column is fixedly connected to the output end of the drive motor. The outer side of the rotating column passes through the inner side of the bottom support plate and is fixedly connected to the middle of the screening frame. A screening traction assembly is installed on the outer side of the screening frame to achieve efficient screening of seeds.

[0008] A collection frame is fixedly connected to the top center of the bottom support plate, a fixing plate is fixedly connected to the lower left side of the support sleeve, an air pump is fixedly connected inside the fixing plate, an air extraction pipe is fixedly connected to the output end of the air pump, the left side of the collection frame is fixedly connected to the bottom end of the air extraction pipe, and a collection component is installed inside the collection frame for screening out debris and cleaning soil from the seeds.

[0009] Furthermore, the collecting component has a connecting column nested inside, a collecting filter frame is fixedly connected to the inner side of the connecting column, a plurality of limiting frames are fixedly connected to the right side of the collecting frame, and positioning blocks are fixedly connected to both sides of the connecting column, with the outer sides of the positioning blocks correspondingly inserted into the interior of the limiting frames.

[0010] Furthermore, the screening traction assembly includes multiple collection filter frames fixed around the perimeter of the screening frame, an external discharge filter frame fixedly connected to the outer side of the collection filter frames, and an external discharge pipe fixedly connected to the inner side of the lower side of the mounting ring.

[0011] Furthermore, a limiting arc groove is provided on the outer right side of the screening frame, and multiple lubricating balls are rotatably connected to the inner side of the mounting ring, with the outer side of the lubricating balls slidably connected to the inside of the limiting arc groove.

[0012] Furthermore, multiple support rods are fixedly connected to the outer circumference of the rotating column, and the outer sides of the support rods are respectively fixedly connected to the inner side of the screening frame.

[0013] Furthermore, an outer lever plate is fixedly connected to the right side of the connecting column to provide leverage for disassembling the connecting column.

[0014] Furthermore, a sealing sleeve is fixedly connected to the outside of the connecting column.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the rotation of the rotating column drives the screening frame to rotate, and the collection filter frame drives the outer discharge filter frame to rotate. The seeds inside the screening frame are quickly discharged to the inside of the outer discharge filter frame as they tumble, and are discharged through the inclined discharge pipe, thereby improving the screening efficiency of the device and accelerating the screening of seeds.

[0017] 2. In this utility model, the air pump generates suction force on the air extraction pipe, thereby expelling the air inside the collection frame to the outside, creating suction force. The soil and impurities inside fall into the collection filter frame and are then extracted to the outside for cleaning, improving the convenience of cleaning the soil and impurities generated during screening and facilitating the daily use of the device.

[0025] 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.

[0026] Reference Figure 1 , Figure 3 and Figure 5This utility model provides an embodiment of a rotary seed sieving device, comprising: a bottom support plate 1 for bottom support; mounting blocks 2 fixedly connected to both sides of the top of the bottom support plate 1; a support sleeve 3 fixedly connected to the top of the mounting blocks 2; a sieving frame 5 disposed inside the support sleeve 3; a mounting ring 4 fixedly connected to the right inner side of the support sleeve 3; the outer side of the sieving frame 5 rotatably connected to the inner side of the mounting ring 4; a drive motor 10 fixedly connected to the left side of the support sleeve 3; a rotating column 21 fixedly connected to the output end of the drive motor 10; the outer side of the rotating column 21 penetrating the inner side of the bottom support plate 1 and fixedly connected to the middle of the sieving frame 5. The screening frame 5 is equipped with a screening traction assembly for efficient seed screening. The screening traction assembly includes multiple collection filter frames 15 fixed around the outside of the screening frame 5. An external discharge filter frame 14 is fixedly connected to the outside of the collection filter frame 15. An external discharge pipe 6 is fixedly connected to the lower inside of the mounting ring 4. A limiting arc groove 16 is opened on the right side of the outside of the screening frame 5. Multiple lubricating balls 17 are rotatably connected around the inside of the mounting ring 4. The outside of the lubricating balls 17 is slidably connected to the inside of the limiting arc groove 16. Multiple support rods 22 are fixedly connected around the outside of the rotating column 21. The outside of the support rods 22 are respectively fixedly connected to the inside of the screening frame 5.

[0027] When the screening equipment is working, the seeds to be screened are first placed into the screening frame 5. The drive motor 10 is started to drive the rotating column 21 and the support rod 22 to rotate synchronously, thereby driving the screening frame 5 and the outer discharge filter frame 14 to rotate as a whole. Under the action of centrifugal force, the seeds in the screening frame 5 continuously tumble and diffuse outward. Smaller-diameter seeds enter the outer discharge filter frame 14 through the frame holes. Since the outer discharge filter frame 14 adopts an inclined design, the seeds that enter will automatically roll to the right along the inclined surface and finally be quickly discharged through the outer discharge pipe 6. This combination design of rotary screening and inclined flow guide effectively improves the seed separation efficiency and screening speed, and realizes rapid seed grading.

[0028] Reference Figure 2 , Figure 3 and Figure 4A collection frame 9 is fixedly connected to the top center of the bottom support plate 1. A fixing plate 12 is fixedly connected to the lower left side of the support sleeve 3. An air pump 11 is fixedly connected inside the fixing plate 12. An air extraction pipe 13 is fixedly connected to the output end of the air pump 11. The left side of the collection frame 9 is fixedly connected to the bottom end of the air extraction pipe 13. A collection component is installed inside the collection frame 9 for screening debris and cleaning soil in the seeds. A connecting column 20 is nested inside the collection component. A collection filter frame 15 is fixedly connected to the inner side of the connecting column 20. Multiple limiting frames 8 are fixedly connected to the right side of the collection frame 9. Positioning blocks 18 are fixedly connected to both sides of the connecting column 20. The outer sides of the positioning blocks 18 are respectively inserted into the inner side of the limiting frames 8. An outer push plate 7 is fixedly connected to the right side of the connecting column 20 for leveraging the disassembly of the connecting column 20. A sealing sleeve 19 is fixedly connected to the outer side of the connecting column 20.

[0029] During the screening process, the vacuum pump 11 evacuates the inside of the collection frame 9 through the vacuum pipe 13, creating a negative pressure suction at the bottom slot of the support sleeve 3. This suction draws the mud and debris from outside the outer filter frame 14 into the collection filter frame 15. After the impurities are collected, the outer push plate 7 pulls the connecting column 20 outward, allowing the collection filter frame 15 to be removed from the collection frame 9 for quick cleaning. This negative pressure adsorption combined with the detachable collection device significantly improves the convenience of impurity cleaning and makes equipment maintenance more efficient.

[0030] Working principle: Seeds to be screened are placed inside the screening frame 5. The drive motor 10 is then started, rotating the rotating column 21. The simultaneous rotation of the rotating column 21 and the support rod 22 generates rotational force on the screening frame 5. The collecting filter frame 15 connects to the inner side of the outer discharge filter frame 14, thus synchronously rotating the screening frame 5 and the outer discharge filter frame 14. The inner wall of the screening frame 5 contacts the seeds, causing them to tumble and disperse outwards. The seeds are then discharged through the holes in the screening frame 5 and enter the inner side of the outer discharge filter frame 14, accelerating the rapid separation of the seeds. Furthermore, when the seeds enter the inner side of the outer discharge filter frame 14, they are dispersed along with the outer discharge filter frame 14. The inclined surface of the filter frame 14 rolls to the right, thereby discharging the seeds outward through the external discharge pipe 6, improving the efficiency of seed separation and sieving. During the seed sieving process, the air pump 11 is activated, and the air inside the collection frame 9 is accelerated and pulled outward through the air extraction pipe 13, thereby transmitting suction force to the top of the collection frame 9. The groove at the bottom of the support sleeve 3 generates suction force, thereby drawing the soil and debris generated outside the external filter frame 14 into the interior of the collection filter frame 15. At this time, the external deflector 7 generates an outward pulling force on the connecting column 20, thereby detaching the collection filter frame 15 from the interior of the collection frame 9, thus completing the cleaning and collection of soil.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
