An ultrasonic atomization cultivator for precise spraying from the inside of the root system to the outside

Abstract

The invention provides an ultrasonic atomization cultivation device for accurate spraying from the interior of a root system to the exterior of the root system. The ultrasonic atomization cultivation device comprises a water tank, an atomization room, a piezoelectric vibrator, fog outlet pipelines and an axial flow fan. The ultrasonic atomization cultivation device is characterized in that the water tank is communicated with the atomization room through a water inlet pipeline, and the axial flow fan is arranged on the side wall of the atomization room. The piezoelectric vibrator is arranged in the atomization room and electrically connected with a direct-current power supply. The atomization room is communicated with the fog outlet pipelines, and the fog outlet pipelines comprise the first fog outlet pipeline and the second fog outlet pipeline. The first fog outlet pipeline is connected with the atomization room, penetrates through the side wall of a colonization hole and is connected with the side wall of the colonization hole in a sealed mode. One end of the second fog outlet pipeline is open and the open end of the second fog outlet pipeline extends to the interior of the root system of a plant. A plurality of branch fog outlet pipelines are arranged on the second fog outlet pipeline, and fog outlet holes are formed in the branch fog outlet pipelines. The ultrasonic atomization cultivation device for accurate spraying from the interior of the root system to the exterior of the root system overcomes the defects that the interior of the root system of the plant is dry and the interior of the root system of the plant is wet, so that fog drops of the root system of the plant are evenly distributed, and the fog cultivation effect is improved.

Description

technical field [0001] The invention relates to an ultrasonic atomization cultivator, in particular to an ultrasonic atomization cultivator which sprays precisely from the inside of the root system to the outside. Background technique [0002] The structure of the ultrasonic atomizer is simple, the distribution of the droplets is uniform, and it can realize the ultrasonic sterilization of the nutrient solution, so it has great application prospects in the field of atomization cultivation. [0003] The root system of aeroponic crops is extremely developed, and the existing atomization cultivation system sprays outside the root system. The invention patent with the notification number CN101167438B provides a "low-frequency ultrasonic atomization cultivation device". It is difficult for fog droplets to reach the core of the root system, and the distribution of fog droplets inside the root system is extremely uneven, which leads to the phenomenon of "wet outside and dry inside" ...

AI Technical Summary

Problems solved by technology

It is difficult for the mist to reach the core of the root system, and the distribution of the mist inside the root system is extremely uneven, which leads to the phenomenon of "wet outside and dry inside" in the root system during aeroponics, that is, the outer area of ​​​​the root system is full of mist droplets, but the core is not foggy. The arrival of the drops greatly affects the effect of the aeroponics, and even leads to the failure of the aeroponics

On the other hand, the existing ultrasonic sprayers in atomization cultivation still have disadvantages such as low water and fertilizer utilization efficiency, high energy consumption, and damage to the chemical structure of the nutrient solution through cavitation.
