[0002] With the modernization and scaling up of agricultural production, the requirements for seed quality are increasing. Seed screening, as an important part of agricultural production, directly affects crop yield and quality.

[0003] Traditional seed screening methods rely heavily on manual labor or simple mechanical devices, which are not only inefficient but also produce poor screening results, making it difficult to meet the needs of modern agriculture. During the screening process, missed or incorrect screenings are prone to occur, affecting the final seed quality.

[0004] Therefore, we propose a seed screening device for agricultural sowing. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art and provide a seed screening device for agricultural sowing.

The bottom of the two sets of upright plates that are close to each other has a guide plate fixedly connected downward from right to left. The bottom surface of the casing has a vertically mounted discharge port at the end of the guide plate that is downward.

[0007] Preferably, the interior of the chassis is a hollow rectangle, and the outer surface of the chassis door is provided with a horizontal ventilation groove, which is connected to the interior of the chassis. A filter screen is fixedly connected to the inner surface of the ventilation groove.

[0008] Preferably, the two sets of upright plates are horizontally parallel, the overall shape of the screening frame is a vertical cylinder, the top of the screening frame is an open circular groove, the feed inlet is located above the top surface of the screening frame, and the cross-section of the feed inlet is a frustum that is wider at the top and narrower at the bottom.

[0009] Preferably, the bottom of each set of fixing posts extends vertically downward into the interior of the circular groove, and the inner two sides of the circular groove are horizontally provided with limiting grooves. One end of each set of fixing posts is horizontally T-shaped inside the circular groove, and the two sides of the fixing post surface are movably engaged inside the corresponding limiting groove.

[0010] Preferably, the output end of the drive motor is horizontally fixedly equipped with a main gear that drives the screening frame to rotate. One end of the main gear passes horizontally through the inside of the square groove and meshes with the surface of the caliper. A waste pipe for discharging filtered waste is vertically installed on the bottom surface of the screening frame. The bottom of the waste pipe passes vertically through the guide plate and the outer surface of the machine box. A valve is provided on the outer surface of the waste pipe.

[0011] Preferably, a fixing frame is vertically fixed to the top of the side surface of the two sets of upright plates that are close to each other.

[0012] This utility model provides a seed screening device for agricultural sowing. It has the following beneficial effects:

[0013] This agricultural seed screening device, during use, involves placing seeds into the inlet, which then conveys them to the screening frame. Each set of fixed columns supports the screening frame, and the bottom of each column can rotate within a circular groove. Starting the drive motor causes the main gear to rotate via its output. The main gear meshes with a caliper, and this interaction rotates the entire screening frame. Each set of rotating wheels ensures a smoother rotation, subjecting the seeds inside the frame to centrifugal force. Through the screening holes, the seeds are sieved out and fall onto the top surface of the guide plate. The inclined guide plate, in conjunction with the outlet, discharges the filtered seeds from the machine casing, thus separating seeds from impurities and improving the screening efficiency.
