Atomized culture device for vegetables

Abstract

The invention provides an atomized culture device for vegetables. The culture device is characterized in that a base, a nutrient solution recovery mechanism and planting steps are concentrically mounted in the culture device in sequence from bottom to top, the planting steps are fixed on the nutrient solution recovery mechanism, and the nutrient solution recovery mechanism is mounted on the base through tires in a rolling manner; a prime mover and transmissionmechanism is located below the base and is in transmission connection with the bottom of the nutrient solution recovery mechanism, and the nutrient solution recovery mechanism drives the planting steps to rotate on the base under the driving of the prime mover and transmissionmechanism; an atomizing assembly is arranged in a planting step cavity and connected with an external nutrient solution box; through holes are formed in both the base and the nutrient solution recovery mechanism, nutrient solution spray sprayed by the atomizing assembly is liquefied in the planting step cavity, then flows out through the through holes in the base and the nutrient solution recovery mechanism and flows back to the nutrient solution box through a pipeline, and the nutrient solution is recycled. According to the atomized culture device for the vegetables, incidence rateand culture cost of the vegetables can be reduced while vegetable yield is increased and vegetable quality is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a vegetable atomization cultivation device. Background technique [0002] Vegetables are an essential food for people's daily life, but with the increasing population, decreasing land and the influence of seasons on the growth of vegetables on the ground, the supply of vegetables in winter and spring is in short supply; some areas even cannot grow vegetables all year round, and some areas People's lives are difficult, and the output of vegetables cultivated by the original land resources is limited, so the traditional land production and nutrient solution culture are difficult to meet people's needs. At the same time, with the improvement of urban people's living standards and quality of life, the traditional vegetable production methods can produce limited vegetables, and the use of traditional land-based fertilizers is seriously exceeding the standard, which has ...

Problems solved by technology

The main problems of these two kinds of atomized root system culture are: there are generally large droplets in the atomization, and the distribution of the droplets is uneven. Especially when there are many roots in the root box, the problem is more prominent. If it is easier to liquefy at low temperature It condenses into water; for high-speed rotary atomization, it has high requirements on the quality of the motor, and damages often occur during use, which affects the normal use of the entire device; at the same time, the traditional aerosol farming system is a combination of soilless farming system and atomization system. For example, the soilless farming system is connected with an atomization system, and the aerosol cultivation is carried out in a multi-system manner.

However, if the ultrasonic nebulizer is placed in the nutrient solution, since the nebulizer is fixed, it is necessary to control the level of the nutrient solution to ensure that the liquid inlet of the nebulizer is higher than the level of the nutrient solution to affect the atomization. At the same time, since the nebulizer is set in the water tank, when the nebulizer fails, it is necessary to disassemble the culture device before replacing the nebulizer, which will cause trouble in maintenance; the application number is 201510347468.2, the patent name In the patent document called "a mist generating device", it is disclosed that an atomizing device is embedded in the middle of the float so that the atomizing device is always located in the liquid to ensure continuous mist generation.

The position of the mist outlet is controlled by changing the rotation direction of the fan to ensure the nutrient solution and humidity required by the plant roots and leaves, and the mist generating device of the invention is arranged on the planting plate, which can be easily and simply replaced from the planting plate, but The nutrient solution falling from the roots is mixed with the initial nutrient solution, which will destroy the previous ratio of nutrient solution, and at the same time will continue to accumulate germs, which is not good for plant growth; the application number is 201620337046.7, and the patent name is "New Water Atomization Cultivation Device In the patent document of ", disclose a kind of three-dimensional atomized culture method, but it is because the side of the round platform of the culture rack is short-sighted, so that the plants are always in an oblique growth state, so that the plants with larger roots at the top are cultivated Inverted growth is easy to occur during the process, and at the same time, the number of temperature sensors will increase as the number of plants increases, which not only costs high, but also interferes with the structure and space, which is not conducive to the absorption of nutrient solution by the roots of the plants
