Description

Technical Field

[0001] This utility model relates to the field of seed screening technology, specifically to a seed screening device that prevents clogging. Background Technology

[0002] As is well known, seed screening is one of the methods for cleaning crop seeds. Seed sieves with different mesh sizes and shapes are used to remove impurities (mud clods, sand particles, crop seeds, weed seeds, insect galls, husks, etc.), chaff, and small seeds, while retaining large, plump, and uniform high-quality seeds to improve seed quality.

[0003] Chinese patent (publication number: CN219168905U) discloses an anti-clogging seed screening device. The device features a conical block inside a conical barrel, with multiple pull ropes around its perimeter. One end of each pull rope has a mounting block, which is fixed to the inner wall of the conical barrel with screws. The bottom of the conical block is located inside the discharge pipe. When seeds fall, the conical block diverts the flow, preventing them from concentrating in the discharge pipe and thus preventing clogging during discharge. This improves seed discharge efficiency and consequently, seed screening efficiency, making it highly practical. However, the filter screen becomes clogged due to excessive residual impurities, and cannot be automatically cleared, making it cumbersome to use.

[0004] To address the aforementioned issues, we have made improvements by proposing an anti-clogging seed screening device. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model provides a seed screening device for preventing clogging, including a housing. The upper and lower ends of the housing are respectively provided with an inlet and an outlet. A material frame is provided inside the housing. A drive mechanism is installed on the outside of the material frame. Multiple through-hole slots are opened at the bottom of the material frame. A connecting frame is provided below the material frame. Multiple mounting frames are fixedly connected to the top of the connecting frame, and the mounting frames extend into the through-hole slots. A filter screen is connected to the top of the mounting frames. Telescopic electric cylinders are fixedly connected to the four corners of the bottom of the material frame. A connecting rod is fixedly connected to the output end of the telescopic electric cylinder, and the top of the connecting rod is fixedly connected to the connecting frame.

[0007] As a preferred technical solution of this utility model, the driving mechanism includes a pair of side plates, which are respectively fixedly connected to the left and right sides of the material frame. A rotating plate is hinged to the bottom of each pair of side plates, and a column and a motor are respectively installed at the bottom of the pair of rotating plates. The column and the motor are fixedly installed inside the outer shell.

[0008] As a preferred embodiment of this utility model, the bottom end of the material frame is fixedly connected to a plurality of guide posts, and the side of the connecting frame is fixedly connected to a plurality of collars, with the collars sleeved on the outside of the guide posts.

[0009] As a preferred embodiment of this utility model, guide rails are fixedly connected to both the front and rear sides of the inner shell, and sliders are slidably connected inside the guide rails. A telescopic rod is hinged to the outer side of the slider, and the end of the telescopic rod is hinged to the outer side of the material frame.

[0010] As a preferred embodiment of this utility model, the feed inlet is provided with a plurality of guide blocks and guide rings, which are alternately arranged.

[0011] As a preferred embodiment of this utility model, the upper surfaces of the guide ring and the guide block are both fixedly connected with multiple blocking strips.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model uses a telescopic electric cylinder to connect a connecting rod, causing the mounting frame and filter screen to exit the through hole groove, thus opening the through hole groove. Then, the drive mechanism works to make the material frame swing, causing impurities to fall and be discharged from the outlet, thus assisting in the discharge of impurities and making it more convenient to use.

[0014] 2. In this utility model, after the seeds enter the feed inlet, they pass through the guide block and the guide ring in sequence. The seeds are blocked by the blocking strips on the guide block and the guide ring, which reduces the falling speed of the seeds and prevents the seeds from rushing out of the feed frame.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Example: Figure 1 - Figure 4 As shown, a seed screening device for preventing clogging includes a housing 1. The upper and lower ends of the housing 1 are respectively provided with an inlet 2 and an outlet 3. A quantitative feeding mechanism is installed at the top of the inlet 2. A material frame 4 is provided inside the housing 1. A driving mechanism is installed on the outside of the material frame 4. Multiple through-hole slots 11 are opened at the bottom of the material frame 4. A connecting frame 15 is provided below the material frame 4. Multiple mounting frames 13 are fixedly connected to the top of the connecting frame 15, and the mounting frames 13 extend into the interior of the through-hole slots 11. A filter screen 12 is connected to the top of the mounting frames 13. Telescopic electric cylinders 17 are fixedly connected to the four corners of the bottom end of the material frame 4. A connecting rod 16 is fixedly connected to the output end of the telescopic electric cylinder 17, and the top of the connecting rod 16 is fixedly connected to the connecting frame 15.

[0023] Seeds enter the outer casing 1 through the feed inlet 2 and then fall into the feed frame 4. The drive mechanism moves the feed frame 4 inside the outer casing 1. Qualified seeds pass through the filter screen 12 and are discharged from the outlet 3. Impurities remain inside the feed frame 4. After a batch of seeds has been screened, the telescopic electric cylinder 17 operates to disengage the mounting frame 13 and the filter screen 12 from the through hole groove 11 via the connecting rod 16, opening the through hole groove 11. Then, the drive mechanism swings the feed frame 4, causing impurities to fall and be discharged from the outlet 3, thus assisting in the discharge of impurities and making it more convenient to use.

[0024] Specifically, such as Figure 1 and Figure 4 As shown, the drive mechanism includes a pair of side plates 19, which are fixedly connected to the left and right sides of the material frame 4 respectively. The bottom ends of the pair of side plates 19 are hinged with rotating plates 20. The bottom ends of the pair of rotating plates 20 are respectively equipped with columns 21 and motors 22, and the columns 21 and motors 22 are fixedly installed inside the housing 1. The operation of the motor 22 drives one of the rotating plates 20 to rotate. The rotating plate 20 drives the side plate 19 to rotate, thereby causing the material frame 4 to move inside the housing 1. The side plate 19 and rotating plate 20 on the other side of the material frame 4 move on the column 21, cooperating with the movement of the material frame 4.

[0025] Specifically, such as Figure 4 As shown, multiple guide posts 14 are fixedly connected to the bottom of the material frame 4, and multiple collars 18 are fixedly connected to the side of the connecting frame 15. The collars 18 are sleeved on the outside of the guide posts 14. During the downward movement of the connecting frame 15, the collars 18 move down along the guide posts 14 to guide the connecting frame 15 and make its movement more stable.

[0026] Specifically, such as Figure 1 As shown, guide rails 5 are fixedly connected to the front and rear sides of the interior of the outer shell 1. A slider 6 is slidably connected inside the guide rail 5. A telescopic rod 7 is hinged to the outside of the slider 6, and the end of the telescopic rod 7 is hinged to the outside of the material frame 4. When the material frame 4 moves inside the outer shell 1, the slider 6 slides inside the guide rail 5, and supports the material frame 4 in conjunction with the extension and retraction of the telescopic rod 7, making the material frame 4 more stable.

[0027] Specifically, such as Figure 1 and Figure 2 As shown, the feed inlet 2 is equipped with multiple guide blocks 8 and guide rings 9. The guide blocks 8 and guide rings 9 are arranged alternately. Multiple blocking strips 10 are fixedly connected to the upper end face of the guide rings 9 and guide blocks 8. After the seeds enter the feed inlet 2, they pass through the guide blocks 8 and guide rings 9 in sequence. The seeds are affected by the blocking strips 10 on the guide blocks 8 and guide rings 9, which reduces the falling speed of the seeds and prevents the seeds from rushing out of the feed frame 4.

[0028] Working principle: Seeds enter the outer shell 1 through the feed inlet 2, and pass through the guide block 8 and guide ring 9 in sequence. The seeds are slowed down by the blocking strips 10 on the guide block 8 and guide ring 9, and then fall into the material frame 4. The motor 22 drives one of the rotating plates 20 to rotate. The rotating plate 20 drives the side plate 19 to rotate, which in turn makes the material frame 4 move inside the outer shell 1. Qualified seeds pass through the filter screen 12 and are discharged from the discharge port 3. Impurities remain inside the material frame 4. When a batch of seeds has been screened, the telescopic electric cylinder 17 works to push the mounting frame 13 and the filter screen 12 out of the through hole groove 11 through the connecting rod 16, so that the through hole groove 11 is opened. Then the drive mechanism works to make the material frame 4 swing, so that the impurities fall and are discharged from the discharge port 3.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
