Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vegetable special fertilizer, in particular to a vegetable special fertilizer and a small package dispensing device thereof. BACKGROUND

[0002] In agricultural production, the planting of vegetables is extremely critical for the demand for fertilizer. With the improvement of people's living standards, higher requirements have been put forward for the quality, yield and stress resistance of vegetables. The traditional vegetable fertilizer has an unreasonable nutrient ratio. Commonly, the nitrogen, phosphorus and potassium ratio cannot accurately adapt to the needs of different growth stages of vegetables. Moreover, the lack of trace elements is also a common problem. During the growth of vegetables, elements such as zinc and boron play an indispensable role in physiological processes such as photosynthesis, pollen germination and pollination and fertilization. However, traditional vegetable fertilizers often ignore the addition of these elements, making vegetables prone to small leaf disease, flowers but no fruit and other symptoms, which seriously affects the quality and yield of vegetables. In addition, traditional vegetable fertilizers are mostly 40kg / bag or 50kg / bag, which is not convenient for use in current greenhouse planting and other application scenarios.

[0003] However, during the small packaging 20 or 25kg / bag dispensing process, especially when handling fertilizer particles with more dust (vegetable fertilizer uses a high amount of powder coating powder to avoid caking), the outer surface of the packaging bag, especially the area where the label or logo is to be pasted, is prone to adhere to material powder, dust or other contaminants. If the label is pasted directly on such a contaminated surface, the adhesion of the label will be greatly reduced, and phenomena such as edge lifting and falling off are likely to occur. This not only affects the appearance of the product, but more importantly, it can lead to the loss of product information (such as batch number, production date, ingredient description, etc.), which poses risks to product traceability, use and compliance.

[0004] In current automated packaging production lines, although the sealing process has been highly automated, the function of effectively cleaning the specific area of the packaging bag at the same time or immediately after sealing to ensure that the label is firmly pasted is often not fully integrated and optimized. Some production lines may need to add independent cleaning stations or use manual wiping methods, which undoubtedly increases the complexity, floor space and production cost of the equipment, and reduces the overall automation level and production efficiency.

[0005] Therefore, how to integrate an automatic cleaning device in the existing automated packaging and sealing process to effectively clean the surface of the attached dust and improve the adhesion reliability of the label is a technical problem that needs to be solved in the current packaging equipment field. SUMMARY

[0006] The purpose of the present application is to provide a special vegetable fertilizer, which effectively improves the quality, stress resistance and yield of vegetables through unique formula design and advanced tower granulation process.
