Abstract
The invention discloses a uniform lighting system for stand column cultivation in a greenhouse. Through the transmission of a nut slider, a lead screw, a connection rod and a rocker, a light reflection curtain driving motor drives a light reflection curtain on the north wall of the greenhouse to rotate; the upper ends of a plurality of cultivation stand columns are respectively supported by a same water pipe through transmission stand columns and plastic linear bearings; the lower ends of the cultivation stand columns are respectively supported by the ground through thrust bearings; and the two ends are capable of rotating relative to the ground and the water pipe. One end of a plastic rack which is parallel to the water pipe is connected onto the wall of the greenhouse through a spring and the other end is dragged by a winding drum driving motor through a steel wire rope and a winding drum. Limiting guard boards at a plurality of positions are capable of ensuring the positioning of the flexible plastic rack while restraining and ensuring the meshing between a gear and the plastic rack. By realizing uniform lighting for stand column cultivation in the greenhouse with low cost, low energy consumption, simplicity and reliability, not occupying space and effectively preventing the transmission system from generating new sheltering to the light, the uniform lighting system for stand column cultivation in the greenhouse can be used for the uniform lighting for stand column cultivation in the greenhouse.
Description
Technical field
The present invention relates to agricultural equipment field, particularly a kind of greenhouse pillar is cultivated even lighting system.
Background technology
Column is cultivated by cultivating on the column of establishing, and can make full use of greenhouse space, thereby greatly improve the output of vegetables and flowers, has wide promotion prospect.But, compared with the cultivation of ground, the column of establishing forms light and blocks, causing cultivating before the inhomogeneous and greenhouse of the daylighting of column the moon (backlight) sun (to light) face the daylighting problem of non-uniform between (north) each column after (south) gives prominence to, thereby had a strong impact on the yield and quality of vegetable or flower, become the key obstacle of column culture technique application.The propositions such as Li Pingping have also been developed rotation screw cultivation upright post system (Li Pingping, Liu Jizhan. utility model patent: rotation screw stereo flower cultivating system (patent No.: ZL03279436.3)), but it only drives by motor the rotation daylighting that realizes the single small-sized column of balcony, cultivation for the large quantification great pillar in greenhouse is produced, its lower end single point supporting poor stability, and the installation of single motor drive, cost and operation maintenance are all difficult to meet the actual needs of agricultural production.Xing Cuihua, Chen Baifeng, Zhang Lihua etc. utilize Reflecting curtain carry out even daylighting in greenhouse (Xing Cuihua. reflective membrane is in the application [J] in plastic greenhouse and orchard. new rural area, 2005 (7): 12; Chen Baifeng. the application [J] of Agricultural reflector in Vegetable Production in Solar Greenhouse: Shanxi Agricultural science, 2009,37 (5): 53～55; Zhang Lihua. the research [J] of greenhouse by solar heat Reflecting curtain suspension angles. Agriculture in Jiangxi journal 2010,22 (6): 160～161.), but ground or its inclination angle of manual adjustment are fixed on in Reflecting curtain lower end, there is the burning seedling phenomenon near ground, and take up room and operate inconvenience, daylighting lack of homogeneity, is difficult to meet the even daylighting needs that greenhouse pillar is cultivated.Not yet there are at present even lighting equipment and technical method for greenhouse pillar cultivation.
