Soilless culture device with automatic spraying function

Abstract

The invention discloses a soilless culture device with an automatic spraying function. The soilless culture device comprises a bracket and cultivation frames; the upper end of the bracket is fixedly connected with a water supply tank; the top end of the water supply tank is fixedly connected with a water inlet; the lower part of the water supply tank is fixedly connected with water outlets; the upper part of the water supply tank is fixedly connected with a motor; and the inner side of the water supply tank is fixedly connected with the cultivation frames. According to the soilless culture device with the automatic spraying function of the invention, the multi-layer water supply tank structure is adopted, so that water cultured plants at each layer can be automatically watered through theautomatic water supply system; the complete water supply system can be built through the bracket, so that nutrient solutions and water can be automatically supplied to cultivated plants at high layers; and cultivated plants at the same layer can be directly sprayed with water through a mobile spraying kettle.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a soilless cultivation device with an automatic spraying function. Background technique [0002] Soilless cultivation refers to a cultivation method in which water, peat or forest leaf humus, vermiculite and other media are used as substrates for plant roots to fix plants, and the plant roots can directly contact the nutrient solution. The composition of the nutrient solution in soilless cultivation is easy to control, and It can be adjusted at any time; but the existing soilless cultivation device also has the following problems in practical application: [0003] 1. In the process of soilless cultivation, due to the needs of crop growth, constantly choose to absorb nutrients and absorb a large amount of water, coupled with the evaporation and consumption of the cultivation bed surface, liquid supply pipeline and liquid supply pool, the concentration of nutrient solution has ch...

[0004] 2. In the process of soilless cultivation, it is also necessary to regularly spray water on the cultivated vegetable leaves. For the convenience of spraying, most of the cultivation devices now consist of one layer or lower layers. The cultivation area is too large and the space cannot be used rationally, resulting in certain waste of space resources;

[0005] 3. In the process of soilless cultivation, the waste nutrient solution needs to be replaced regularly to maintain the stability of the nutrient solution in the pool. The existing replacement of the nutrient solution is cumbersome and requires special extraction of the nutrient solution in the nutrient pool.
