Description

Technical Field

[0001] This utility model relates to the field of seed screening device technology, and in particular to a seed screening device based on agricultural product planting. Background Technology

[0002] Different varieties of seeds used in agricultural production vary significantly in terms of growth period, yield, disease resistance, drought tolerance, lodging resistance, and adaptability. Seed plumpness is important; unplump seeds may not have matured properly, or they may be due to disease or premature aging in the seed production field. Unplump seeds can affect germination or later disease resistance. Poor seed size and shape uniformity is mainly due to inadequate seed selection and grading. This results in uneven germination, leading to seedlings of varying sizes coexisting, affecting field uniformity. Furthermore, the amount of broken good seeds is also a concern, as seed breakage can occur during threshing, drying, or selection. Some broken seeds may germinate, but they are more susceptible to disease or develop abnormal seedlings. If more than half of the seed is broken, germination may not occur at all. Therefore, seed screening is necessary.

[0003] For example, Chinese Patent Application No. 202420014684.X discloses a seed screening device, including a screening box. The screening box has an inlet at the top and a guide pipe at the bottom. The bottom surface of the left end of the screening box has a slag discharge port. The screening box has an inclined plate inside, and the bottom end of the inclined plate is fixedly connected to the slag discharge port. A filter frame is provided above the inclined plate, and a filter screen is slidably connected inside the filter frame. The left and right ends of the filter frame are respectively provided with a first rotating shaft and a second rotating shaft. Both the first rotating shaft and the second rotating shaft are movably connected to the screening box. The left end of the first rotating shaft is rotatably connected to a convex plate. The upper surface of the convex plate has several equally spaced serrated blocks. A shaking device is provided above the convex plate. The shaking device includes a fixed box. The right end of the fixed box is fixedly connected to the screening box. The right end of the screening box is provided with a rotating device. The seed screening device disclosed in this utility model not only has a better screening effect, but also facilitates material discharge.

[0004] However, in the aforementioned seed screening device, although the filter screen is shaken by a corresponding shaking device to screen seeds during use, seeds may become stuck on the inner walls on both sides during shaking, and some seeds may still not fall off, affecting the screening process. Therefore, those skilled in the art have provided a seed screening device based on agricultural product cultivation to solve the problems mentioned in the background art. Utility Model Content

[0036] The auxiliary screening mechanism 6 includes a mounting shell 61. A drive motor 62 is fixed to the inner wall of one side of the mounting shell 61. A cast iron rotating frame 63 is fixed to the outer side of the output shaft of the drive motor 62. A cast iron column 64 is fixed to the outer side of the cast iron rotating frame 63. A cast iron mounting plate 65 is fixed to the inner wall of one side of the mounting shell 61. A cast iron limiting sleeve 66 is fixed to the outer side of the cast iron mounting plate 65. A cast iron mounting rod 67, which passes through the other side of the cast iron limiting sleeve 66, is movably inserted into one side of the cast iron limiting sleeve 66. An impact connecting block 68 is fixed to one end of the cast iron mounting rod 67. A movable limiting sleeve 69 is installed at one end of the cast iron mounting rod 67. The interior of the movable limiting sleeve 69... A through slot is provided, the size of which is adapted to the size of the cast iron column 64, allowing the cast iron column 64 to move within the through slot of the corresponding movable limiting sleeve 69. The mounting shell 61 and the metal fixing frame 1 are fixedly connected. The drive motor 62 and the mounting shell 61 are fixed together by bolts, which can ensure a stable connection between the mounting shell 61 and the drive motor 62. A through hole is provided inside the mounting shell 61, the size of which is adapted to the size of the impact connecting block 68, allowing the impact connecting block 68 to move normally in the horizontal direction. A limiting hole is provided inside the cast iron limiting sleeve 66, the size of which is adapted to the size of the cast iron mounting rod 67.

[0037] The positioning mechanism 9 includes an anti-slip mat 91, a metal mounting block 92 fixed to one side of the anti-slip mat 91, a metal threaded rod 93 fixed to one side of the metal mounting block 92, a plastic handle 94 fixed to one end of the metal threaded rod 93, two positioning threaded sleeves 95 threadedly connected to the outer side of the metal threaded rod 93, an L-shaped limiting sleeve 96 fixed to the outer side of the bottom collection container 7, anti-slip texture provided on the outer side of the metal handle 8, the corresponding surface of the L-shaped limiting sleeve 96 fitting against the outer side of the anti-slip mat 91, and a through hole opened inside the metal fixing frame 1, the size of which is adapted to the size of the metal threaded rod 93.

[0038] Working principle: During seed screening, seeds are fed into the seed feed hopper 3. Then, the outer shaking device of the double-layer seed screening frame 5 is activated to make the double-layer seed screening frame 5 shake. The two layers of filters in the double-layer seed screening frame 5 can screen the seeds. The screened seeds fall through the discharge port of the double-layer seed screening frame 5. The filtered dust and debris fall directly into the bottom collection container 7 for collection. During filtration, the drive motor 62 can also be activated, so that the output shaft of the drive motor 62 drives the cast iron rotating frame 63 to rotate. The cast iron column 64 pushes the moving limit sleeve 69 to move, so that the cast iron mounting rod 67 moves back and forth, and the impact connecting block 68 intermittently impacts the outer side of the double-layer seed screening frame 5, assisting the outer side of the double-layer seed screening frame 5 to vibrate and shake slightly, reducing the seed dust. During seed screening, the presence of some seeds stuck in the material facilitates the normal falling of seeds. When the bottom collection container 7 is placed at the bottom of the double-layer seed screening rack 5 to collect dust and debris, the anti-slip mat 91 on one side of the metal mounting block 92 is attached to the outside of the bottom collection container 7. At the same time, the L-shaped limiting sleeve 96 on the outside of the bottom collection container 7 is attached to the anti-slip mat 91. By rotating the two positioning threaded sleeves 95 on the outside of the metal threaded rod 93, the corresponding surfaces of the two positioning threaded sleeves 95 are attached to the outside of the metal fixing frame 1, thus fixing the position of the metal threaded rod 93 and the anti-slip mat 91. This ensures that the anti-slip mat 91 is stably attached to the outside of the bottom collection container 7, and it is also relatively easy to remove or clean the bottom collection container 7.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
