Uniform lighting system for stand column cultivation in greenhouse

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 [0001] The invention relates to the field of agricultural equipment, in particular to a greenhouse column cultivation uniform lighting system. Background technique [0002] The pillar cultivation can make full use of the greenhouse space by cultivating on the erected pillars, thereby greatly increasing the output of vegetables and flowers, and has broad promotion prospects. However, compared with ground cultivation, erected columns form light shielding, resulting in uneven lighting on the shady (backlit) and sunny (light-facing) sides of the cultivation columns and uneven lighting between the front (south) and rear (north) columns of the greenhouse. The problem is prominent, which has seriously affected the yield and quality of vegetables and flowers, and has become a key obstacle to the application and promotion of column cultivation technology. Li Pingping and others have proposed and developed a movable spiral cultivation column system (Li Pingping, L...

Problems solved by technology

However, compared with ground cultivation, erected columns form light shielding, resulting in uneven lighting on the shady (backlit) and sunny (light-facing) sides of the cultivation columns and uneven lighting between the front (south) and rear (north) columns of the greenhouse. The problem is prominent, which has seriously affected the yield and quality of vegetables and flowers, and has become a key obstacle to the application and promotion of column cultivation technology

Li Pingping and others have proposed and developed a movable spiral cultivation column system (Li Pingping, Liu Jizhan. Utility model patent: movable spiral three-dimensional flower cultivation system (patent number: ZL03279436.3)), but it only realizes a single small balcony by motor drive. The rotating lighting of the column, for the cultivation and production of a large number of tall columns in the greenhouse, the stability of the single-point support at the lower end is poor, and the installation, cost and operation and maintenance of a single motor independent drive are difficult to meet the actual needs of agricultural production

Xing Cuihua, Chen Baifeng, Zhang Lihua, etc. used reflective curtains to uniformly light the greenhouse Application in Production [J]: Shanxi Agricultural Sciences, 2009, 37(5): 53~55; Zhang Lihua. Study on Hanging Angle of Reflective Curtain in Solar Greenhouse [J]. Journal of Jiangxi Agricultural Sciences 2010, 22(6): 160~161 .), but the lower end of the reflective curtain is fixed on the ground or its inclination is manually adjusted, and the phenomenon of burning seedlings close to the ground occurs, and it takes up space and is inconvenient to operate, and the uniformity of lighting is poor, which is difficult to meet the uniform lighting needs of greenhouse column cultivation

At present, there is no uniform lighting equipment and technical method for greenhouse column cultivation
