Two rows of parallel supporting piers 9 are arranged in the three-dimensional airing greenhouse; the pulley track 10 is fixed to the support pier 9.
The bottom of the drying disc 11 is respectively provided with four universal wheels 15 which are matched with the pulley rails 10 and can slide on the pulley rails 10; when fruits need to be aired, the fruits needing to be aired are firstly placed on the airing disc 11 and are transported to the three-dimensional airing greenhouse through the transfer trolley 18 shown in fig. 9, workers lift the airing disc on the sliding rail 10 and move the airing disc 11 through the sliding rail 10, the operation is time-saving and labor-saving, and the airing efficiency is improved.
As shown in FIG. 6, the humidity sensors 12 are uniformly arranged on the beam 5, are positioned at the inner side of the greenhouse film 6, and are connected with the ventilation device 13 and the multifunctional operation room 14. When the temperature and humidity sensor 12 senses that the air humidity in the greenhouse reaches 75-85%, the temperature and humidity sensor 12 transmits a signal to a ventilation device 13 control switch of the multifunctional operation room 14 to control the ventilation device 13 to be automatically opened to blow out water vapor in the greenhouse outdoors, and when the air humidity is reduced to 45-50%, the ventilation device 13 is automatically stopped. After the ventilation system is started, the indoor temperature is reduced along with the reduction of the air humidity, but the reduction range is about 10 ℃, and the great influence on the airing of fruits cannot be caused. Besides being automatically switched on and off according to signals of the temperature and humidity sensor 12, the ventilation device 13 can also be manually controlled by controlling the switch through the ventilation device 13 of the multifunctional operating room 14, and the fruits can still be quickly aired and dried.
The ground of the three-dimensional air-drying greenhouse is a concrete hardened ground 7, so that a large amount of heat can be absorbed in the daytime and released at night, and the greenhouse can be kept at a higher temperature; and the transfer trolley is convenient to pass.
As shown in fig. 7, two rows of parallel support piers 9 with the size of 0.25m × 0.25m × 0.4m and the distance between the support piers of 1.5-1.8m are arranged in the multifunctional three-dimensional airing greenhouse; the pulley track 10 is fixed to the support pier 9.

The bottom of the airing tray 11 is made of a bamboo mat 17, so that the airing tray is not rusted and is easy to deform, and the appearance and the quality of aired fruits are not influenced. The drying plate frame 16 is made of galvanized angle iron in a welded mode, the effect of manufacturing the bamboo mat 17 is achieved, the drying plate 11 can be placed on the supporting piers 9 conveniently, the universal wheels 15 are arranged at the bottom of the drying plate 11 and can slide on the sliding rails 10, the burden of workers is relieved, and the drying efficiency is improved.
In general, in the fruit ripening season, the illumination intensity temperature is high, and because the three-dimensional multifunctional airing greenhouse basically realizes full-day illumination, the indoor temperature can reach 50-70 ℃, and the real observation shows that the temperature in the greenhouse is basically 1.5-2.1 times of the outdoor temperature. Namely, when the outdoor temperature is 25 ℃, the temperature in the drying greenhouse can reach 50-55 ℃.
The comparative research shows that the same amount of fruits can be aired under the same conditions, the open air airing needs 4-6 days, the multifunctional three-dimensional airing greenhouse can be used for ensuring that the fruits are not influenced by external factors, the all-weather airing is realized, the airing time can be shortened to 3-4 days, and the market opportunity can be preempted. Moreover, the quality of the aired fruits is high, and higher economic and social benefits can be generated.
It should be noted that the above-mentioned embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the protection scope of the present invention.
