Plant greenhouse and stepless light-adjusting method thereof

Abstract

The invention discloses a plant greenhouse which mainly comprises a greenhouse roof, greenhouse side walls, an outer net device, an inner net device, wet curtains, side windows and seedbeds. The greenhouse roof is arranged above the greenhouse side walls, the outer net device is arranged above the greenhouse roof, the inner net device is arranged below the greenhouse roof, the tops of the wet curtains are fixed on the greenhouse side walls, the side windows are arranged on the outer sides of the wet curtains, the seedbeds are arranged below the greenhouse roof, inclined through holes are densely distributed on an outer net, a vertical plane identical with the inclining direction of the inclined through holes is parallel to a vertical plane where an upper rotating shaft is positioned, and fixed supporting legs are arranged on the lower portion of each seedbed frame. The plant greenhouse has the advantages that the whole outer net can realize one inclining action, the inclined through holes are densely distributed on the outer net, and light-transmitting areas of the inclined through holes change along inclining of the outer net, so that light-transmitting effect of the outer net can be adjusted, stepless light adjusting is realized, and light-adjusting effect is better.

Description

[0001] This patent application is a divisional application for an invention patent application (the application number is 2011101945461, the application date is 2011-7-11, and the name is plant greenhouse) technical field [0002] The invention relates to agricultural equipment, in particular to a greenhouse for plants. Background technique [0003] 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 set in the greenhouses. When in use, the artificial simulation of climate is realized by automatic adjustment of temperature, humidity, light, etc., so as to provide a suitable production environment for plants. [0004] The existing greenhouse mainly includes the top of the greenhouse, the side walls of the greenhouse, the outer net device, the inner mesh device, the wet curtain, the side window and the seedbed.

Problems solved by technology

[0005] 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

[0007] 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 planting in greenhouses, thereby affecting the yield
