AI Technical Summary

Technical Problem

In existing soilless cultivation technology, the fixed installation of the nutrient solution tank causes the nutrient solution to remain stagnant, which easily leads to stratification and sedimentation, resulting in uneven nutrient solution composition and affecting plant growth, as well as the yield and quality of soilless cultivation.

Method used

Design an automatic nutrient solution circulation supply device for hydroponics. The device uses a water pump assembly to achieve automatic circulation of the nutrient solution, and a shaking frame assembly to make the upper nutrient solution tank rotate back and forth to promote uniform mixing of the nutrient solution. The device also incorporates an epoxy resin smooth coating to reduce nutrient solution residue and a filter cartridge to remove impurities.

Benefits of technology

It achieves uniform supply of nutrient solution, ensures the stability of the plant growth environment, improves the yield and quality of hydroponics, extends the service life of the device, and ensures the hygiene and safety of the nutrient solution.

Abstract

This utility model relates to the field of hydroponics, specifically disclosing an automatic nutrient solution circulation supply device for hydroponics, including a nutrient solution circulation mechanism and a support mechanism. The nutrient solution circulation mechanism includes an upper nutrient solution tank assembly and a lower nutrient solution tank assembly, with a water pump assembly installed between the upper and lower nutrient solution tank assemblies. The support mechanism includes a support frame assembly, on which a shaking frame assembly is mounted. The support frame assembly includes a support frame, on which a set of limiting baffles are fixedly installed. This utility model uses a connecting rod that rotates left and right to drive the limiting frame to rotate left and right, thereby causing the upper nutrient solution tank to rotate left and right, with its rotation limited by the limiting baffles. This movement allows the nutrient solution in the upper nutrient solution tank to shake, promoting thorough and uniform mixing of the nutrient solution and preventing uneven nutrient solution composition from affecting plant growth.
