Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, specifically to an automatic coating machine for small-grained seeds. Background Technology

[0002] Seed coating refers to the process of using an adhesive to coat the seed surface with substances such as fungicides, insecticides, micronutrients, plant growth regulators, colorants, and fillers, forming a pellet-shaped seed unit. Coated seeds are heavier, making them suitable for mechanical sowing. The active ingredients in the coating enhance the seed's resistance to adverse conditions, provide nutrients for seedlings, accelerate germination, and promote seedling establishment. There are two main types of seed coating methods: manual coating and mechanical coating. Manual coating involves placing the seeds in a large pot or plastic bag, adding an appropriate proportion of seed coating agent, and then manually rolling and stirring to evenly coat the seed surface. While simple to operate, these methods often suffer from problems such as multiple seeds and insecure coating. Mechanical coating utilizes various seed coating machines.

[0003] Existing seed coating machines require manual operation to add seeds, powders, and liquids separately into a mixing container for mixing, resulting in low work efficiency and uneven mixing. Utility Model Content

[0059] Please refer to Figure 1 , Figures 5 to 7This utility model provides an automatic coating machine for small-grained seeds, including a machine body 1 and a coating mechanism 2, a seed material supply mechanism 3, a powder supply mechanism 4, and a liquid supply mechanism 5 installed on the machine body 1. The coating mechanism 2 includes a coating box 21, a turntable 22, and a connecting structure 23. The coating box 21 has an inner cavity 211 and a first inlet 212, a second inlet 213, a third inlet 214, and an outlet 215 connecting the inner cavity 211 to the external environment. The turntable 22 is disposed in the inner cavity 211, and the connecting structure 23 is disposed in the inner cavity 211 and located above the turntable 22. The connecting structure 23 is provided with a connecting channel 231. 1. The inlet of the connecting channel 2311 is connected to the first feed inlet 212 and the second feed inlet 213, and the outlet of the connecting channel 2311 is located at the center of the inner cavity 211; the seed material supply mechanism 3 is used to supply seed material to the first feed inlet 212; the powder material supply mechanism 4 is used to supply powder material to the second feed inlet 213; the liquid supply mechanism 5 includes a liquid outlet pipe 51 and a nozzle 52, the liquid outlet pipe 51 passes through the third feed inlet 214 and the connecting channel 2311, and the liquid outlet of the liquid outlet pipe 51 extends out of the outlet of the connecting channel 2311, and the nozzle 52 is connected to the liquid outlet of the liquid outlet pipe 51.

[0060] In this embodiment, the powder supply mechanism 4 and the seed material supply mechanism 3 add powder and seed material to the first feed port 212 and the second feed port 213, respectively. The connecting structure 23 is used to concentrate the powder and seed material into the center of the inner cavity 211, and then drive the turntable 22 to rotate, so that the powder and seed material are evenly distributed on the turntable 22, thereby making the powder and seed material mix more evenly. Then, the nozzle 52 sprays liquid, and then the turntable 22 rotates, so that the powder coats the outer surface of the seed material. In this way, no manual operation is required, the work efficiency is high, and the mixing is more uniform.

[0061] Furthermore, in this embodiment, the liquid outlet pipe 51 extends from the third feed inlet 214 into the connecting channel 2311, and the liquid outlet of the liquid outlet pipe 51 extends outside the outlet of the connecting channel 2311; the nozzle 52 is connected to the liquid outlet of the liquid outlet pipe 51, thereby positioning the liquid outlet pipe 51 at the center of the inner cavity 211, facilitating the uniform spraying of liquid into the inner cavity 211, and preventing liquid from being sprayed into the connecting channel 2311, thus avoiding blockage of the connecting channel 2311. Additionally, the width of the connecting channel 2311 is greater than the diameter of the liquid outlet pipe 51 to prevent blockage by powder and seed materials.

[0062] Furthermore, referring to Figures 5 to 7In this embodiment, the connecting structure 23 is configured as a connecting hopper 231 that runs vertically through the interior, with the tip of the connecting hopper 231 pointing downwards and the upper end of the connecting hopper 231 connected to the upper cavity wall of the inner cavity 211; the connecting channel 2311 is formed in the connecting hopper 231, and the outlet of the connecting hopper 231 is larger than the diameter of the liquid outlet pipe 51, so that powder and seed material can fall from the outlet of the connecting hopper 231 onto the turntable 22.

[0063] Specifically, continue to refer to Figures 5 to 7 In this embodiment, the turntable 22 includes a disc body 221 and a guide cone 222. The axis of the disc body 221 extends vertically, and the guide cone 222 is connected to the center of the disc body 221 and coaxially arranged with the disc body 221, with the tip of the guide cone 222 pointing upwards. On the one hand, materials and powders can fall directly from the outlet of the connecting hopper 231 onto the guide cone 222, slide down the outer surface of the guide cone 222 onto the disc body 221, and be distributed around the periphery of the guide cone 222. This allows the materials and powders to be more evenly distributed on the disc body 221 during mixing, making subsequent uniform mixing easier. On the other hand, when the turntable 22 rotates, the guide cone 222 prevents the powder and materials from moving to the center of the turntable 22, ensuring that the materials and powders always move between the periphery of the guide cone and the periphery of the disc body 221, improving mixing efficiency and coating quality.

[0064] In this embodiment, refer to Figure 5 The coating mechanism 2 further includes a cover plate 24 and a drive assembly 25. The cover plate 24 is movably connected to the discharge port 215, allowing it to move closer to or further away from the discharge port 215. The drive assembly 25 drives the cover plate 24 to move. After coating is completed, the drive assembly 25 drives the cover plate 24 to open, the turntable 22 rotates, and the coated seeds flow out from the discharge port 215 under the rotational force within the inner cavity 211.

[0065] Specifically, refer to Figure 5 and Figure 8The coating mechanism 2 includes a rocker arm 26 and a rotating shaft 27. One end of the rocker arm 26 is connected to the rotating shaft 27, and the other end of the rocker arm 26 is connected to the cover plate 24. The drive assembly 25 includes a drive motor 251 and at least two gears 252. The drive motor 251 is mounted on the coating box 21, and the two gears 252 mesh with each other. One of the gears is connected to the drive shaft of the drive motor 251, and the other end is connected to the rotating shaft 27. In this embodiment, the drive assembly 25 is located on the upper side of the cover plate 24. The rocker arm 26 extends vertically, and the upper end of the rocker arm 26 is rotatably connected to the coating box 21 through the rotating shaft 27. The lower end of the rocker arm 26 is connected to the cover plate 24. The drive shaft of the drive motor 251 rotates, causing the two gears 252 to rotate, which in turn drives the rotating shaft 27 to rotate. This causes the lower end of the rocker arm 26 to lift upwards, thereby opening the discharge port 215 with the cover plate 24, or lowering the lower end of the rocker arm 26 to close the discharge port 215 with the cover plate 24. Thus, the structure is simple and stable.

[0066] In another embodiment, the drive assembly 25 may also be configured as a cylinder, the cylinder seat of which is connected to the coating box 21, and the cylinder rod of which is connected to the cover plate 24, for driving the cover plate 24 away from or closer to the discharge port 215.

[0067] In this embodiment, refer to Figure 5 The coating mechanism 2 further includes a motor 28 and a guide plate 29. The motor 28 is located on the lower side of the coating box 21 and is connected to the turntable 22. The rotation of the drive rod of the motor 28 drives the turntable 22 to rotate. The guide plate 29 is connected to the outer side of the coating box 21 and is positioned corresponding to the discharge port 215. The guide plate 29 forms a downwardly angled guide channel, which allows the coated seeds to fall out of the discharge port 215 in an orderly manner, facilitating the collection of the coated seeds.

[0068] In this embodiment, refer to Figure 2 , Figure 3 and Figure 12 The liquid supply mechanism 5 further includes a storage tank 53, a connecting pipe 54, and a metering booster pump 55. The storage tank 53 is used to store liquid. The two ends of the connecting pipe 54 are respectively connected to the storage tank 53 and the inlet of the metering booster pump 55. The outlet of the metering booster pump 55 is connected to one end of the liquid outlet pipe 51, and the other end of the liquid outlet pipe 51 is connected to the nozzle 52, which is configured as an atomizing nozzle. The metering booster pump 55 is used to spray the liquid in the storage tank 53 through the connecting pipe 54 and the liquid outlet pipe 51 from the atomizing nozzle.

[0069] To ensure precise quantity of seed material input, refer to Figure 9 and Figure 10 The seed material supply mechanism 3 includes a first mounting frame 31, a first vibration box 32, a first vibrator 33, a first weighing sensor 34, a first discharge box 35, and a first dropping plate 36. The first mounting frame 31 is mounted on the machine body 1. The first vibration box 32 is mounted on the first mounting frame 31 and has a first vibration groove 3211. The side wall of the first vibration groove 3211 has a first opening 3212.

The first dropping plate 36 is movably connected to the first discharge box 35 to open or close the outlet of the first discharge box 35.

[0070] In this embodiment, the first vibration groove 3211 is used to hold the seed material. The first vibrator 33 drives the first vibration box 32 to vibrate, causing the seed material to fall from the first opening 3212 into the first discharge box 35. Since the first discharge box 35 is supported by the first weighing sensor 34, the weight of the seed material inside the first discharge box 35 can be obtained. After the weight of the seed material in the first discharge box 35 reaches a preset value, the first vibrator 33 stops operating. Then, the first dropping plate 36 opens the outlet of the first discharge box 35, and the material in the first discharge box 35 enters the inner cavity 211 through the first inlet 212. Thus, automatic quantitative addition of the seed material is completed, ensuring precise feeding.

[0071] Furthermore, in this embodiment, reference is made to Figures 9 to 11 The seed material supply mechanism 3 further includes a first guide member 37, a first hopper 38, a first rotating motor 391, and a first rocker arm 392.

The first box body 321 is connected to the first support 322, and the first vibration groove 3211 is formed in the first vibration box 32. The first support 322 is fixedly connected to the first base 323 through the first elastic support member 324. The first exciter 33 is connected to the first support 322. The first exciter 33 uses a phase-shift triggering method to set two vibration amplitude levels, thereby adjusting the seed dropping speed. The first elastic support member 324 is located between the first support 322 and the first base 323 to buffer the dynamic load transmitted to the first box body 321.

[0073] Specifically, refer to 13 to Figure 15 The powder supply mechanism 4 includes a second mounting frame 41, a second vibration box 42, a second vibrator 43, a second weighing sensor 44, a second discharge box 45, and a second dropping plate 46. The second mounting frame 41 is mounted on the machine body 1. The second vibration box 42 is mounted on the second mounting frame 41 and has a second vibration groove 4211. The side wall of the second vibration groove 4211 has a second opening 4212. The second vibrator 43 is connected to the second vibration box 42 and is used to drive the second vibration box 42 to vibrate toward the second opening 4212. The second weighing sensor 44 is mounted on the second mounting frame 41 and is located on one side of the second vibration box 42. The second discharge box 45 is connected to the second weighing sensor 44. The inlet of the second discharge box 45 corresponds to the second opening 4212, and the outlet of the second discharge box 45 communicates with the second feed inlet 213. The second dropping plate 46 is movably connected to the second discharge box 45 to open or close the outlet of the second discharge box 45.

[0074] In this embodiment, the second vibration groove 4211 is used to feed powder into the second discharge box 45. The second vibration groove 4211 contains powder, which is vibrated by the second vibrator 43, causing the powder to fall from the second opening 4212 into the second discharge box 45. Since the second discharge box 45 is supported by the second weighing sensor 44, the weight of the seed material in the second discharge box 45 can be obtained. After the weight of the seed material in the second discharge box 45 reaches the preset value, the second vibrator 43 stops operating. Then, the second dropping plate 46 opens the outlet of the second discharge box 45, and the material in the second discharge box 45 enters the inner cavity 211 through the second inlet 213. In this way, the automatic quantitative addition of powder is completed, and the feeding is precise.

[0075] In addition, continue to refer to Figures 13 to 15 In this embodiment, the powder supply mechanism 4 further includes a second guide member 47, a second hopper 48, and a second rotary motor 49.
