[0001] This utility model relates to the field of seed processing technology, and in particular to a seed coating device for seed processing. Background Technology
[0002] With the continuous development of society and the continuous progress of science and technology, the technology related to seed processing is also constantly improving. Seed coating is a process in which a seed coating agent containing a variety of ingredients such as insecticides, fungicides, compound fertilizers, trace elements, plant growth regulators, slow-release agents and film-forming agents is evenly coated on the surface of the seed using mechanical or manual methods, forming a smooth and firm film.
[0003] The seed coating equipment currently in use can only coat seeds, but cannot screen seeds or coat larger, high-quality seeds. This results in poor seed coating quality, which is detrimental to the use of the coating equipment. Utility Model Content
[0004] The purpose of this invention is to address the following shortcomings in the existing technology: the seed coating devices currently used can only coat seeds, but cannot screen seeds or coat larger, high-quality seeds, resulting in poor seed coating quality and hindering the use of the coating device. Therefore, this invention proposes a seed coating device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A seed coating device includes a coating box and a screening shell. The screening shell is connected to the coating box via a guide plate. A partition is fixedly connected inside the screening shell. An L-shaped sieve plate is inclined and connected to the partition via multiple first springs. A fixing plate is fixedly connected to one side of the screening shell. A rotating component is provided on the fixing plate.
[0007] Two discharge ports are opened on one side of the screening shell. A feed pipe and two electric push rods are fixedly connected to the screening shell. A sealing cover plate is fixedly connected to the drive end of each electric push rod. A sliding assembly is provided on the screening shell. The sliding assembly includes two sliders that are slidably mounted on the screening shell. Each slider is connected to the corresponding sealing cover plate by a pull rope. A blocking plate is fixedly connected to each slider.
[0008] Preferably, the screening housing has two sliding openings for the slider to slide back and forth, and a second spring is fixedly connected in each sliding opening. The second spring and the slider are fixedly connected, and the cross-section of each slider is I-shaped.
[0009] Preferably, the upper end of the guide plate is fixedly connected to an intercepting plate with a V-shaped cross-section, and the upper surface of the intercepting plate is in contact with the lower surface of the L-shaped screen plate.
[0010] Preferably, a servo motor is fixedly connected to the fixed plate, and the rotating assembly includes a rotating shaft fixedly connected to the drive end of the servo motor, with a first rotating block and a second rotating block fixedly connected to the rotating shaft.
[0011] Preferably, a collection frame is provided inside the screening housing, and two handles are fixedly provided on one side of the collection frame.
[0012] Preferably, both the screening shell and the partition plate have openings for connecting the L-shaped screen plate, and the upper surface of the partition plate is set as an arc surface.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] Seeds are fed into the feed pipe and fall onto an L-shaped sieve plate from both sides of the partition. A servo motor moves the L-shaped sieve plate back and forth to screen the seeds. Smaller seeds pass through the sieve holes and fall into the collection frame. An electric push rod drives the sealing cover plate to move vertically upward, offsetting the sealing cover plate from the corresponding discharge port. Some larger seeds on the L-shaped sieve plate slide through the discharge port onto the guide plate and enter the coating tank inside the coating box. This allows for continuous and thorough screening of the seeds, followed by coating of the larger seeds. The coating quality is high, which is beneficial for the use of the coating device.

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.
[0022] Reference Figures 1-4 A seed coating device includes a coating box 2 and a screening shell 1. The coating box 2 includes a coating tank and a liquid tank. The coating tank and liquid tank are equipped with relevant components for seed coating. Its working principle has been disclosed in document CN220830722U. The screening shell 1 is connected to the coating box 2 via a guide plate 10. A partition plate 15 is fixedly connected inside the screening shell 1. An L-shaped sieve plate 3, arranged at an inclination, is connected to the partition plate 15 via multiple first springs 18. One side of the screening shell 1... A fixed plate 5 is fixedly connected, and a rotating assembly is provided on the fixed plate 5. Two discharge ports are opened on one side of the screening housing 1. A feed pipe 14 and two electric push rods 4 are fixedly connected to the screening housing 1. A sealing cover plate 11 is fixedly connected to the drive end of each electric push rod 4. A sliding assembly is provided on the screening housing 1. The sliding assembly includes two sliders 13 that are slidably mounted on the screening housing 1. Each slider 13 is connected to the corresponding sealing cover plate 11 through a pull rope 12. A blocking plate 16 is fixedly connected to each slider 13.
[0023] Two sliding openings are provided on the screening housing 1 for the sliding of the slider 13. A second spring is fixedly connected in each sliding opening. The second spring and the slider 13 are fixedly connected. The cross-section of each slider 13 is I-shaped. During the movement of the sealing cover 11, the slider 13 will slide along the sliding opening under the elastic force of the second spring, so that the pull rope 12 is always taut. The upper end of the guide plate 10 is fixedly connected to the intercepting plate 17 with a V-shaped cross-section. The upper surface of the intercepting plate 17 is in contact with the lower surface of the L-shaped screen plate 3. The V-shaped intercepting plate 17 can effectively intercept smaller seeds and prevent small seeds that penetrate the L-shaped screen plate 3 from falling onto the guide plate 10.
[0024] A servo motor is fixedly connected to the fixed plate 5. The rotating assembly includes a rotating shaft 7 fixedly connected to the drive end of the servo motor. An electromagnetic brake is provided at the drive end of the servo motor. A first rotating block 6 and a second rotating block 9 are fixedly connected to the rotating shaft 7. The servo motor drives the rotating shaft 7 to rotate back and forth. During the back and forth deflection of the first rotating block 6, it will squeeze and detach from the L-shaped sieve plate 3 multiple times. The L-shaped sieve plate 3 moves back and forth at the same time to facilitate the screening of seeds. During the rotation of the second rotating block 9, it will hit and detach from the lower surface of the guide plate 10 multiple times. The guide plate 10 vibrates so that the seeds above it slide into the coating tank. The connection strength between the guide plate 10 and the screening shell 1 and the coating box 2 is sufficient and there will be no breakage.
[0025] A collection frame 8 is provided inside the screening housing 1. Two handles are fixedly provided on one side of the collection frame 8. Smaller seeds will fall into the collection frame 8 after passing through the sieve holes on the L-shaped sieve plate 3. The collection frame 8 can be pulled out from the screening housing 1 by manually pulling the handles, so as to facilitate the centralized processing of small seeds in the collection frame 8. The screening housing 1 and the partition plate 15 are provided with openings for connecting the L-shaped sieve plate 3. The upper surface of the partition plate 15 is set as an arc surface. The connection between the L-shaped sieve plate 3 and the openings on the screening housing 1 and the partition plate 15 is well sealed, effectively preventing seeds from passing through the openings. The arc surface can prevent seeds from accumulating on the upper surface of the partition plate 15.
[0026] In this invention, in the initial state, both sealing covers 11 are in contact with the surface of the screening housing 1 and seal the two discharge ports. Both blocking plates 16 are in contact with the upper inner wall of the screening housing 1 and are offset from the feed pipe 14. When seeds are put into the feed pipe 14, they will fall from both sides of the partition 15 onto the L-shaped screen plate 3. At the same time, the servo motor drives the rotating shaft 7 to rotate back and forth. During the back and forth deflection of the first rotating block 6, it will squeeze and detach from the L-shaped screen plate 3 multiple times. After the L-shaped screen plate 3 is squeezed and moved, since the two ends of each first spring 18 are fixedly connected to the screening housing 1 and the L-shaped screen plate 3 respectively, the first spring 18 deforms, which allows the L-shaped screen plate 3 to move back and forth, so as to screen the seeds above it. Smaller seeds will pass through the sieve holes on the L-shaped screen plate 3 and fall into the collection frame 8 for collection.
[0027] One of the electric push rods 4 drives the sealing cover plate 11 to move vertically upward. After the sealing cover plate 11 moves, it will be offset from the corresponding discharge port, that is, it will no longer seal and block the discharge port. Some of the large seeds on the L-shaped screen plate 3 will slide through the discharge port onto the guide plate 10 and enter the coating tank in the coating box 2. During the movement of the sealing cover plate 11, the two ends of the non-elastic and wear-resistant pull rope 12 are fixedly connected to the slider 13 and the sealing cover plate 11 respectively. Under the elastic force of the second spring, the slider 13 will slide along the sliding opening, so that the pull rope 12 is always in a taut state until the blocking plate 16 is located directly below the feed pipe 14. The blocking plate 16 can partially block the feed pipe 14, preventing new seeds from falling to one side of the L-shaped screen plate 3. By making the two electric push rods 4 work intermittently and staggered, the seeds can be continuously and fully screened. After that, the large seeds can be coated. The coating quality of the seeds is high, which is beneficial to the use of the coating device.
