Greenhouse

Abstract

The invention discloses a greenhouse, which mainly comprises a greenhouse roof, a greenhouse lateral wall, an outside screen device, an inside screen device, a wet curtain, a lateral window and a seedling bed, wherein the greenhouse roof is arranged above the greenhouse lateral wall; the outside screen device is arranged above the greenhouse roof; the inside screen device is arranged below the greenhouse roof; the top of the wet curtain is fixed on the greenhouse lateral wall; the lateral window is arranged on the outer side of the wet curtain; the seedling bed is arranged below the greenhouse roof; and inclined through holes are distributed on an outside screen densely; and a vertical surface which is consistent with the inclined direction of the inclined through holes is parallel to a vertical surface on which an upper rotating shaft is positioned. The greenhouse has the advantages that: the integral outside screen can incline, the inclined through holes are distributed on the outside screen densely, and the light-transmitting areas of the inclined through holes are changed with the change of the inclination of the outside screen; and thus, the light-transmitting effect of the outside screen is adjustable, a mode of stepless dimming is adopted, and the dimming effect is high.

Description

technical field [0001] The present invention relates to agricultural equipment, in particular to a greenhouse. Background technique [0002] With the development of society and the improvement of automation, plant factories are more and more widely used in agriculture. Plant factories usually mainly include closed spaces such as greenhouses, and plants are placed in greenhouses. When in use, artificial simulation of climate is realized through automatic adjustment of temperature, humidity, light, etc., so as to provide plants with a suitable production environment. [0003] The existing greenhouse mainly includes the greenhouse roof, the side wall of the greenhouse, the external net device, the internal net device, the wet curtain, the side window and the seedbed. The net device is arranged under the roof of the greenhouse, the top of the wet curtain is fixed on the side wall of the greenhouse, the side window is arranged outside the wet curtain, and the seedbed is arranged...

AI Technical Summary

Problems solved by technology

Among them, the external network and the internal network are the main devices for adjusting the light, and the light adjustment is mainly realized by opening or closing the external network and the internal network. In fact, this working method only has two states of on and off, and does not have a real sense In order to be able to really and effectively adjust the light in the greenhouse according to the intensity of sunlight, usually there are multiple layers of external nets or internal nets, and the light transmittance between the nets of each layer is different, and different nets are opened according to needs. Although the adjustment effect is good, it has the disadvantages of complex structure, high cost and inconvenient control.

[0004] The wet curtain is the main equipment for adjusting humidity in the greenhouse. In order to keep the existing wet curtain moist, a pump must be used to fill and humidify the wet curtain after a certain time interval. The water transported by the pump flows down from the top of the wet curtain to make the whole wet curtain The curtain is soaked, but this method has the following two disadvantages: 1. The pump needs to run at intervals, and the power consumption is large; 2. The humidity of the wet curtain is uneven after water injection. The final humidity is low, which brings inconvenience to the humidity control in the greenhouse. During the period of low humidity, it may be necessary to turn on the humidifier to increase the humidity, which causes additional power consumption

[0005] There are usually side windows on the outside of the wet curtain, and the side windows are hung on the side wall of the greenhouse. The bottom frame structure is provided at the bottom of the side window, and the side frame is provided on the side. The upper hook frame and the bottom frame of the existing greenhouse side windows 1. There is a problem of poor sealing at the side frame, and the outside air is easy to form convection with the internal air through the leaks of the hook, bottom frame, and side frame, which brings inconvenience to the temperature control and humidity control of the greenhouse.

[0006] The existing seedbeds are usually fixed. In order to facilitate maintenance, aisles are provided between the seedbeds. Although such a structure is easy to operate, it has the following disadvantages: the accommodation space of the greenhouse is limited, and the seedbeds and aisles occupy a large area. Space, which will inevitably reduce the amount of greenhouse planting, thereby affecting the yield
