Description

Technical Field

[0001] This utility model belongs to the field of Chinese medicinal herb cultivation technology, specifically relating to a seed coating device for Chinese medicinal herb cultivation. Background Technology

[0002] The cultivation of Chinese medicinal herbs is generally divided into two methods: seed grain cultivation and seedling cultivation. Seed grain cultivation refers to the process of planting using seeds as the object. Directly sowing seeds into the soil requires pre-treatment of the seeds with a protective layer, which enhances the seeds' disease resistance and ability to adapt to the soil environment.

[0003] In existing technologies, most seed coating equipment uses a stirring method. However, unlike grain seeds such as corn and wheat, medicinal herb seeds are more fragile, and the stirring process can easily damage them, thus affecting their survival rate. Furthermore, there are few seed coating devices specifically designed for medicinal herb cultivation on the market. Therefore, there is a need to propose a seed coating device for the cultivation of medicinal herbs. Utility Model Content

[0004] To overcome the problem that existing seed coating equipment for Chinese medicinal herbs mostly adopts a stirring structure, which easily causes mechanical damage to fragile seeds and affects seed survival rate, this utility model provides a seed coating equipment for planting Chinese medicinal herbs. This equipment replaces traditional stirring with a rotary mixing method, and uses a flexible liner and guide plate to optimize the material flow path, reducing direct impact between seeds and equipment. At the same time, the controller controls the motor speed and running time to ensure uniform coating without damaging the seeds, effectively improving the disease resistance and adaptability of the seeds.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A seed coating device for planting Chinese herbal medicines mainly includes a frame, a motor, a turntable, a rotating shaft, a limiting frame, a mixing cylinder, and a controller. The motor is installed at the bottom of the frame, and the rotating shaft is rotatably installed at the center of the frame. The rotating shaft is connected to the output end of the motor through a belt drive mechanism. The turntable is fixedly installed on the rotating shaft. The limiting frame is installed in a circumferential array at equal intervals on the turntable. The mixing cylinder is installed on the turntable and is limited by the limiting frame. A cover plate is provided at the top of the mixing cylinder. The controller is installed on the frame, and the motor is electrically connected to the controller to control the motor speed and running time.

[0006] The turntable is divided into a first turntable and a second turntable. Both are waist-shaped structures and are installed on the rotating shaft at a 90° stagger. The staggered design allows the mixing cylinder to generate a dynamic centrifugal force distribution during rotation, which further promotes the uniform mixing of seeds and coating materials.

[0007] The limiting frame includes a limiting column, a limiting block, and a limiting bolt. The limiting column is vertically fixed to the edges of the first and second turntables. The limiting column forms a triangular limiting structure around the mixing cylinder. The limiting block is installed on the top of the limiting column and presses against the upper surface of the cover plate. The limiting bolt is installed on the limiting column and threadedly connected to the cover plate to ensure that the mixing cylinder remains stable during high-speed rotation and to prevent loosening or displacement.

[0008] The flexible inner liner is fixed to the inner wall of the mixing cylinder by an adhesive process. The material is food-grade silicone or rubber. The flexible inner liner can effectively buffer the collision between the seeds and the cylinder wall, effectively buffer the mechanical impact of the seeds during the mixing process, avoid damage to the seeds due to collision, reduce the risk of mechanical damage, and improve the uniformity of the coating material adhesion.

[0009] The mixing cylinder is equipped with guide plates that are spirally distributed on the inner wall of the mixing cylinder. These guide plates are used to guide the flow of coating materials and seeds, reduce local accumulation or dead corners, and enhance the mixing effect, especially when processing materials with poor flowability or easy agglomeration. This ensures that the coating process is efficient and uniform, and can significantly enhance the mixing effect.

[0010] The frame is equipped with legs at the bottom, and anti-slip pads are installed at the bottom of the legs. The anti-slip pads are made of a material with a high coefficient of friction to ensure that the equipment remains stable during operation and to prevent displacement or tipping due to vibration.

[0011] The beneficial effects of this utility model are:

[0012] This equipment uses a turntable to drive the mixing drums, allowing the seeds to roll naturally within the drums. This avoids direct damage to the medicinal herb seeds during mixing, effectively protecting their integrity and improving their survival rate. The turntable's circular motion ensures that the seeds in each mixing drum are processed evenly, guaranteeing uniform coating. The controller allows for convenient control of the motor's speed and running time, enabling flexible adjustment of the equipment's operating parameters based on different medicinal herb seeds and coating requirements, thus improving the equipment's applicability and flexibility. A limit frame restricts the mixing drums, ensuring stable rotation on the turntable and guaranteeing equipment stability while also improving the efficiency of the coating process.

[0018] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0019] This utility model discloses a seed coating device for planting Chinese medicinal herbs. The device mainly includes a frame 1, a motor 2, a turntable 3, a rotating shaft 4, a limiting frame 5, a mixing cylinder 6, and a controller 7. The specific structure and connection relationships of each component are shown in the attached figure. Figure 1 As shown. In practical applications, this equipment replaces the traditional stirring structure with a rotary mixing method, and optimizes the material flow path using a flexible inner lining and guide plate 15, thereby reducing the direct impact between the Chinese herbal medicine seeds and the equipment, ensuring uniform coating without damaging the seeds.

[0020] The frame 1 serves as the basic support structure for the entire equipment. Its bottom is equipped with support legs 16, each fitted with an anti-slip pad made of a high-friction material such as rubber or silicone. This ensures the equipment remains stable during operation and prevents displacement or tipping due to vibration. This design is particularly suitable for outdoor environments such as medicinal herb planting bases, effectively adapting to different ground conditions. The motor 2 is mounted at the bottom of the frame 1 and connected to the rotating shaft 4 via a belt drive mechanism 18. The rotating shaft 4 is rotatably mounted in the center of the frame 1. This layout allows for efficient power transmission from the motor 2 to the rotating shaft 4, while also separating the motor 2 from the mixing drum 6 for easy maintenance and repair.

[0021] A turntable 3 is fixedly installed on the rotating shaft 4. The turntable 3 is divided into a first turntable 8 and a second turntable 9. Both are waist-shaped structures and are installed on the rotating shaft 4 at a 90° angle, so that the mixing cylinder 6 can generate a dynamic centrifugal force distribution during rotation.

[0022] The limiting frame 5 is installed in a circumferential array at equal intervals on the edges of the first turntable 8 and the second turntable 9. The limiting frame 5 consists of limiting columns 10, limiting blocks 11, and limiting bolts 12. The limiting columns 10 are vertically fixed to the edges of the first turntable 8 and the second turntable 9, forming a triangular limiting structure around the mixing cylinder 6. The limiting blocks 11 are installed on the top of the limiting columns 10, pressing against the upper surface of the cover plate 13. The limiting bolts 12 are installed on the limiting columns 10 and threadedly connected to the cover plate 13, thereby ensuring that the mixing cylinder 6 remains stable during high-speed rotation and preventing loosening or displacement. This limiting structure not only improves the safety of the equipment but also facilitates the disassembly and cleaning of the mixing cylinder 6.

[0023] The mixing drum 6 is one of the core components of this equipment. Its inner wall is lined with a flexible inner layer made of food-grade silicone or rubber. This flexible lining effectively buffers the collision between seeds and the drum wall, reducing the risk of mechanical damage and improving the uniformity of the coating material's adhesion. Inside the mixing drum 6, there are guide plates 15 arranged in a spiral pattern on the inner wall to guide the flow of the coating material and seeds, reducing localized accumulation or dead zones. Especially when processing materials with poor flowability or prone to clumping, these spiral guide plates 15 significantly enhance the mixing effect, ensuring an efficient and uniform coating process. A cover plate 13 is located at the top of the mixing drum 6. The cover plate 13 is fixed to the limiting frame 5 by limiting bolts 12, ensuring both airtightness and allowing operators to easily add or remove materials.

[0024] Controller 7 is mounted on one side of the frame 1 and electrically connected to motor 2. It controls the speed and running time of motor 2. Controller 7 integrates a microprocessor and a touchscreen interface. Operators can input the required speed and running time parameters via the touchscreen, and controller 7 will precisely adjust the operating state of motor 2 based on the input parameters. This intelligent control method not only improves the ease of operation of the equipment but also allows for adjustment of operating parameters according to the characteristics of different types of Chinese herbal medicine seeds and patina materials, thereby achieving the best patina effect. For example, for more fragile seeds, a lower speed and shorter running time can be set, while for harder seeds, the speed can be appropriately increased and the running time extended.

[0025] In actual operation, the operator first places the medicinal herb seeds to be coated and the coating material into the mixing drum 6 according to the specified ratio, then covers it with the cover plate 13 and secures it with the limiting bolts 12. Subsequently, the speed and running time of the motor 2 are set via the controller 7. After starting the equipment, the motor 2 drives the rotating shaft 4 to rotate via the belt drive mechanism 18. The rotating shaft 4 drives the first rotating plate 8 and the second rotating plate 9 to rotate synchronously, ensuring that the seeds and coating material in the mixing drum 6 are fully mixed at multiple angles. Simultaneously, the flexible inner lining of the mixing drum 6 buffers the collision between the seeds and the drum wall, while the spiral guide plate 15 guides the material to flow along the drum wall, further reducing local accumulation or dead zones. Throughout the operation, the controller 7 monitors the working status of the motor 2 in real time and automatically adjusts the speed and running time according to preset parameters to ensure an efficient and uniform coating process. After coating is completed, the operator can stop the equipment via the controller 7, loosen the limiting bolts 12, remove the cover plate 13, and remove the coated seeds from the mixing drum 6. The mixing drum 6 is very easy to disassemble and clean. Simply unscrew the limiting bolt 12 completely to remove the mixing drum 6 from the limiting frame 5, thus avoiding cross-contamination between different batches of materials. In addition, the overall structure of the equipment is compact and easy to transport, making it suitable for use in places such as Chinese herbal medicine planting bases.

[0026] Work process:

[0027] The operator first prepares the medicinal herb seeds requiring patina and the corresponding patina material. Then, the seeds and patina material are placed into the mixing drum 6 in a suitable ratio. After placement, the cover plate 13 is placed on top, and the mixing drum 6 is fixed in place using the limiting frame 5. The limiting column 10 of the limiting frame 5 forms a triangular limiting structure around the mixing drum 6, ensuring that the mixing drum 6 will not shake during operation. The limiting block 11 is installed on the top of the limiting column 10 and presses against the upper surface of the cover plate 13. Then, the limiting bolt 12 is used to thread it to the cover plate 13 to further fix the mixing drum 6. Next, the operator sets the speed and running time of the motor 2 through the controller 7. The controller 7 is electrically connected to the motor 2 and can precisely control the operating parameters of the motor 2 to meet the patina requirements of different medicinal herb seeds. After the parameters are adjusted, the motor 2 is started. The output end of the motor 2 drives the rotating shaft 4 to rotate through the belt drive mechanism 18, thereby causing the turntable 3 to start rotating. Since the mixing drum 6 is mounted on the turntable 3, the mixing drum 6 will move along with the rotation of the turntable 3. During the movement of the mixing drum 6, the seeds and coating material inside are mixed under the action of the guide plate 15. The guide plate 15 is spirally distributed on the inner wall of the mixing drum 6. When the mixing drum 6 rotates, the seeds and coating material flow along the spiral path of the guide plate 15, achieving uniform mixing. At the same time, due to the use of this non-stirring coating method, damage to the fragile Chinese herbal medicine seeds is avoided, improving the seed survival rate. When the running time set by the controller 7 is reached, the motor 2 automatically stops running, and the turntable 3 also stops rotating. The operator loosens the limit bolt 12 and the limit block 11, opens the cover plate 13, removes the coated seeds from the mixing drum 6, and cleans the mixing drum 6 again to prepare for the next use.

[0028] In summary, this invention replaces traditional stirring with rotary mixing, optimizes the material flow path using a flexible inner liner and guide plate 15, and combines intelligent control technology to achieve efficient coating treatment of Chinese herbal medicine seeds. This equipment not only significantly reduces mechanical damage to the seeds but also ensures uniform coating and ease of operation, demonstrating broad application prospects and promotional value.
