Description

Technical Field

[0001] The utility model relates to the technical field of rust removal devices, in particular to a rust removal device for a flue-cured tobacco floating seedling greenhouse. Background Art

[0002] Since floating tobacco seedling cultivation can significantly improve seedling quality, enhance tobacco seedling resistance and root development, effectively reduce the occurrence of field diseases, especially mosaic disease, eliminate premature flowering, increase the number of effective leaves, and facilitate the opening of top leaves, tobacco yield and quality are significantly improved; compared with traditional seedling cultivation methods, floating seedling cultivation has outstanding advantages such as saving seeds, saving seedling land, increasing seedling rate, saving labor, improving production efficiency, and saving input costs. It is conducive to the realization of intensive, large-scale and commercial production of tobacco seedlings. Due to the many advantages mentioned above, floating seedling cultivation is widely adopted by international and domestic tobacco production.

[0003] Floating seedling cultivation has become the primary method for flue-cured tobacco production. This method utilizes soilless cultivation techniques within a plastic film greenhouse, where the temperature and humidity are relatively balanced. By properly controlling the temperature and humidity within the plastic film and greenhouse, strong seedlings are cultivated. Therefore, the plastic film and greenhouse framework, as the hardware materials that provide relatively balanced temperature and humidity conditions, are fundamental to the success of floating tobacco seedling cultivation.

[0004] As floating seedling nurseries, greenhouses operate in high temperatures and high humidity year-round. Their supporting frames, made of steel materials like round steel and square steel, typically begin to rust after five years of operation. In severe weather conditions like strong winds, rain, or snow, the steel pipes can twist, deform, or even break, posing a significant safety hazard. Therefore, greenhouse maintenance, especially of steel pipes, has become a critical issue.

[0005] In order to ensure the normal and safe production of flue-cured tobacco floating seedling greenhouses, each seedling factory is equipped with a special maintenance team. The safety of the steel beams, frames and plastic films of the seedling greenhouses are inspected every day. If any problems are found, they will be dealt with in a timely manner to prevent future troubles.

[0006] As the existing devices are used, the shortcomings of the existing technology are gradually exposed, which are mainly manifested in the following aspects:

[0007] First, as for the maintenance of rusted steel pipes in seedling greenhouses, there are two ways to deal with rusted steel pipes. One is to cut them all off and replace them with new steel, because cutting them all off and replacing them with new steel requires a lot of investment.

[0008] Secondly, another way is to remove the rust from the steel pipe, then repaint it, spray it with silver powder, and let it dry before reuse. Currently, the rust removal is done manually by workers using steel brushes, which has low work efficiency.

[0009] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content
