Plant greenhouse

Abstract

The invention discloses a plant greenhouse, which mainly comprises a greenhouse top, a greenhouse side wall, an outer net device, an inner net device, a wet curtain, a side window and a seedbed, wherein the greenhouse top is arranged above the greenhouse side wall; the outer net device is arranged above the greenhouse top; the inner net device is arranged below the greenhouse top; the top of the wet curtain is fixed on the greenhouse side wall; the side window is arranged on the outer side of the wet curtain; the seedbed is arranged below the greenhouse top; inclined through holes are densely distributed in an outer net; and a vertical surface of which the direction 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 plant greenhouse has the advantages that: the whole outer net can realize an inclining action, the inclined through holes are densely distributed in the outer net, and the light penetration area of the inclined through holes is changed along with the inclination of the outer net; therefore, a light penetration effect of the outer net is adjustable, and the plant greenhouse is arranged in a stepless dimming mode which has a better dimming effect.

Description

technical field [0001] The invention relates to an agricultural equipment, in particular to a plant 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 roof of the greenhouse, the side wall of the greenhouse, the external net device, the internal net device, the wet curtain, the side window and the seedbed. Above the roof of the greenhouse, the internal 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 o...

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 the outer net or the inner net is equipped with multiple layers, and the light transmittance between the nets of each layer is different, and different nets are opened according to the needs, so that Although the adjustment effect of this method is good, it has the disadvantages of complex structure, high cost and inconvenient control.

[0004] The wet curtain is the main equipment for adjusting the 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 The wet curtain is soaked, but this method has the following two disadvantages: 1. The pump needs to run at intervals, and the power consumption is relatively large; 2. The humidity of the wet curtain is uneven after water injection, and the humidity is high during water injection. After a period of time, the 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 walls of the greenhouse. The bottom frame structure is provided at the bottom of the side windows, and the side frame is provided on the side. The upper hook frame of the existing greenhouse side windows, There is a problem of poor sealing at the bottom frame and side frame, and the external 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 set 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
