Automatic rock wool nutrient solution detecting device for agricultural greenhouse

The invention relates to an automatic rock wool nutrient solution detecting device for an agricultural greenhouse. The device comprises a horizontal movement module, a rotating module, a syringe movement module, a syringe liquid suction module, a sensor movement module and a device cleaning and waste liquid recovering module. The horizontal movement module is connected with the rotating module through a bottom plate. The rotating module is connected with the syringe movement module through a connecting plate. The syringe liquid suction module is installed on a syringe supporting plate of the syringe movement module. The sensor movement module is installed on the bottom plate through an aluminum alloy profile. The device is used for extracting a rock wool nutrient solution and detecting the pH value, electric conductivity and other parameters of the solution and is a special detecting device integrating automatic collecting, analyzing and cleaning. The device has a series of advantages of being small in size,
