Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and in particular to a fertilizer injection device for dynamic monitoring of fertilizer injection volume in fertilizer tanks. Background Technology

[0002] In the field of agricultural irrigation and fertilization, traditional fertilization devices generally suffer from problems such as low precision in fertilizer injection control, uneven fertilizer mixing, and easy clogging. Specifically: Insufficient monitoring of fertilizer application: Most equipment relies on manual estimation or simple flow meters, making it difficult to track fertilizer consumption in real time, resulting in excessive or insufficient fertilization, which affects crop growth and wastes resources.

[0003] Poor concentration stability: The lack of real-time monitoring of the electrical conductivity (EC) and pH of the fertilizer solution makes it impossible to dynamically adjust the ratio, which easily leads to local concentration deviations.

[0004] Therefore, in order to solve the aforementioned problems, we propose a fertilizer injection device for dynamic monitoring of fertilizer injection volume in fertilizer tanks. Utility Model Content
