Description

Technical Field

[0001] The invention relates to the technical field of seed coating, in particular to a seed coating device and method. Background Art

[0002] Seed coating device is a kind of equipment used for coating seeds. Its main function is to evenly wrap one or more layers of protective coating on the surface of seeds to improve the germination rate, disease resistance, stress resistance and storage period of seeds. Coating materials usually include fertilizers, pesticides, plant growth regulators, etc., which can effectively prevent the invasion of pests and diseases, enhance the adaptability of seeds, and promote the growth of seeds in adverse environments. Seed coating devices generally include feeding systems, stirring systems, spraying systems, drying systems, etc. to ensure that the coating on the surface of seeds is uniform and firm. Modern seed coating devices also focus on automation and intelligent operation, which can improve production efficiency and operation accuracy.

[0003] The conventional seed coating device in the prior art, especially the mixing drum part thereof, has some obvious deficiencies. Firstly, the conventional mixing drum is large in size and cannot be disassembled, which means that after each batch of seed coating is completed, the coating liquid adhering to the inside of the mixing drum needs to be cleaned for a long time, which not only increases the complexity of the operation, but also increases the production cycle and labor intensity, resulting in a decrease in the overall work efficiency. At the same time, the cleaning process of the conventional mixing drum may not be able to completely remove the residual coating liquid, which may have an adverse effect on the quality of the next batch of seeds, especially when handling different types of coating liquids, the risk of cross contamination is relatively high. Secondly, the conventional mixing drum is not easy to be used, and the quality of the next batch of seeds is not good. The stirring direction of the traditional mixing drum is too single, usually only clockwise stirring is used for mixing, while counterclockwise stirring is used to export the coated seeds. The single stirring direction limits the mixing effect and easily leads to uneven distribution of the coating liquid, thereby affecting the coating quality on the seed surface. This uneven coating may lead to a decrease in the germination rate of the seeds, or deficiencies in disease resistance and stress resistance, affecting the growth effect of the crop. In addition, the single stirring direction also limits the adaptability to seeds of different specifications, making it difficult to meet different production needs, and reducing the flexibility and application range of the equipment. For this reason, we propose a seed coating device and method. Summary of the invention

The first transmission column transmits kinetic energy to the corresponding components through the first kinetic energy transmission mechanism and the second kinetic energy transmission mechanism. When the first kinetic energy transmission mechanism is in operation, it drives the rotating platform and the seed holding mechanism to rotate, causing the seeds to tumble inside the material barrel. At the same time, the second kinetic energy transmission mechanism drives the driving coupling sleeve with the embedded permanent magnet to rotate, driving the transmission coupling rod to rotate. The transmission coupling rod further drives the stirring shaft, the connecting plate and multiple stirring blades to rotate in the material barrel to ensure that the coating liquid and the seeds are fully mixed, thereby achieving uniform coating.

In particular, through the design of the second kinetic energy transmission mechanism, the rotation speed and strength of the stirring blades are optimized, further improving the coating effect. In addition, the close cooperation between the lifting mechanism and the sealing cover effectively avoids the leakage of the coating liquid, ensuring the stability of the equipment operation and the high efficiency of the seed coating.

After the material barrel 901 is placed on the rotating seat 501, the lifting mechanism 4 is started, and the lifting mechanism 4 lifts up the material barrel 901 and the sealing cover 903, so that the top of the sealing cover 903 is tightly fitted with the anti-slip sheet 708, thereby ensuring that the coating liquid is evenly stirred. Subsequently, the driving component 2 is started to drive the turntable 305 to rotate, and simultaneously drives the lifting mechanism 4, the rotating platform 5, the first kinetic energy transmission mechanism 6, the limit clamping mechanism 7, the second kinetic energy transmission mechanism 8 and the seed holding mechanism 9 to revolve.

The planting coating device eliminates the limitation of a single stirring direction through the linkage of multiple mechanisms, can more effectively stir the coating liquid, and ensure uniform coating. In particular, through the design of the second kinetic energy transfer mechanism 8, the rotation speed and strength of the stirring blade 9014 are optimized, further improving the coating effect. In addition, the close cooperation between the lifting mechanism 4 and the sealing cover 903 effectively avoids the leakage of the coating liquid, ensuring the stability of the equipment operation and the high efficiency of the seed coating.
