TECHNICAL FIELD

[01] The utility model relates to the technical field of Dendrobium planting, in particular to a Dendrobium planting greenhouse with automatic defogging function

BACKGROUND

[02] Dendrobium is an orchidaceae aerophyte and many species of it are precious traditional Chinese medicines. For example, Dendrobium candidum can nourish yin and stomach, moisten lung to arrest cough, fight cancer and prolong life, etc. In addition, most flowers of Dendrobium are beautiful and colourful, and their flowering period can last for several months, which is of great value for beautifying home and viewing. Therefore, Dendrobium has a broad market at both home and abroad, and its price also remains high for a long time.

[03] In recent years, the planting area of Dendrobium in China is expanding, and its good economic benefits have been affirmed by most farmers as well. The existing planting method of Dendrobiummainly adopts greenhouses, but at night or rainy days, Dendrobium cannot get the necessary light, which will cause slow growth and decreased yield. At the same time, in the weather with large temperature difference between day and night, it is easy to appear a large amount of spray in the greenhouse, resulting the humidity inside the greenhouse to exceed the normal range, which is not conducive to the normal growth of Dendrobium.

[04] The purpose of the utility model is to provide a Dendrobium planting greenhouse with automatic defogging function to solve the problems raised in the background technology.

[05] To achieve the above purpose, the utility model provides the following technical solutions:

[06] A Dendrobium planting greenhouse with automatic defogging function is comprised of a main body, winding drums, supporting skeletons and seedbeds. There is a door installed on one side of the main body and a mounting rack installed on the top of the greenhouse main body. And at the bottom sides of the main body, fastening nails are uniformly installed. At both sides of the mounting rack, there are winding drums with rotating shafts at the middle of the interior. Besides, both sides of the rotating shafts are connected with winding drums through bearing blocks. The outsides of the rotating shafts are wrapped with curtains with pull cords at two sides far away from the rotating shafts. Supporting skeletons with spray water pipes evenly arranged at the middle position are installed inside the greenhouse main body, wherein the bottom ends of the spray water pipes are evenly installed with spray nozzles. On one side of the main body, there are blast pipes evenly arranged and an exhaust fan is arranged inside each blast pipe; on the other side, there are discharge pipes evenly arranged, and a blower is arranged inside each discharge pipe. In the main body of the greenhouse, there are lighting lamps evenly arranged at the top, seedbeds at the bottom and electric heating pipes on both sides. Wherein, the two bottom sides of each lighting lamp are provided with brightening plates. Moreover, a humidity sensor is installed on the side close to the blast pipes, and under it, a single chip microcomputer is installed on the inner wall. Similarly, a temperature sensor is installed under the single-chip microcomputer. The output ends of the temperature sensor and the humidity sensor are electrically connected with the input end of the single chip microcomputer through wire, and the output ends of the single chip microcomputer are respectively electrically connected with the input ends of the electric heating pipes, the exhaust fans and the blowers through wire.

[07] Preferably, the outer side of the curtain is provided with a light shielding layer, and the inner side is provided with a reflective layer.

[08] Preferably, the top of the supporting skeletons is evenly arranged with longitudinal and horizontal stiffeners.

[09] Preferably, there are barbs at the external sides of the fastening nails.

[010] Preferably, there are dust-proof net covers on the air inlet and outlet of blast pipes (3) and discharge pipes.

[011] Compared with the prior art, the utility model has the following beneficial effects:

[012] In virtue of the winding drums with curtains inside, it is convenient for the Dendrobium planting greenhouse with automatic defogging function to put down the curtains on the main body of the greenhouse in rainy days or at night. And the utility model can strengthen the lighting effects through utilizing curtains to reflect the light emitted by the lighting lamps inside main body, so that only a few lighting lamps are needed to meet the lighting requirements of planting Dendrobium, thereby saving electric energy. At the same time, the transmission area of natural light can be adjusted through curtains, which makes it easy to control the lighting intensity, so as to facilitate the better growth of Dendrobium. The humidity sensor is installed to facilitate the utility model to detect the humidity inside the greenhouse. When a large amount of spray is generated in the greenhouse due to the temperature difference between day and night, the humidity sensor can turn on blowers to eliminate spray and at the same, turn on exhaust fans to suck external air through the single chip microcomputer, so as to achieve the automatic defogging function. In addition, sucking external air into the greenhouse by the exhaust fans can keep the oxygen needed for the growth of Dendrobium. It is easy for the utility model to detect the temperature inside the greenhouse by installing a temperature sensor. When the temperature inside the greenhouse is low, the temperature sensor turns on the electric heating pipe through the control of the single chip microcomputer, and the electric heating pipe starts heating to maintain the temperature required for the growth of Dendrobium. At the same time, the spray water pipes with spray nozzles make it easy to irrigate Dendrobium in large area quickly, which is much more convenient to plant Dendrobium.
