Anti-seismic anti-wind automatic agricultural plastic greenhouse

Abstract

The invention discloses an anti-seismic anti-wind automatic agricultural plastic greenhouse. Arch-shaped steel frames connected through transverse supporting steel strips are arranged between a firstarch-shaped brick and a second arch-shaped brick in a greenhouse frame. A first winding shaft and a second winding shaft are installed in a limiting box fixed to the greenhouse frame. Plastic cloth iswound on the first winding shaft and the second winding shaft. The edges of the plastic cloth are fixedly provided with limiting rings. A first water reservoir and a second water reservoir are arranged at the lower portion of the greenhouse frame. A first water conveying pump is arranged in the first water storage pool. A second water conveying pump is arranged in the second water storage pool. An automatic watering device in the greenhouse frame is composed of a limiting guide rail, a vertical water conveying pipe, a transverse water conveying pipe, watering nozzles, straight rail teeth, a limiting gateway, a limiting slider, a supporting plate, a third electric motor and a transmission gear, and the problems are solved that an existing agricultural plastic greenhouse cannot realize theeffect of automatically winding and unwinding plastic cloth, cannot realize automatic watering, cannot realize water resource conservation, and is poor in anti-seismic anti-wind performance.

Description

technical field [0001] The invention relates to the technical field of plastic greenhouses, in particular to an earthquake-resistant and wind-resistant automatic agricultural plastic greenhouse. Background technique [0002] The plastic greenhouse makes full use of solar energy, has a certain heat preservation effect, and can adjust the temperature and humidity in the greenhouse within a certain range through the plastic cloth roll film. Therefore, in the northern part of my country, plastic greenhouses mainly play the role of thermal insulation cultivation in advance of spring and delay in autumn. Generally, spring can be advanced 30-35 days, and autumn can be delayed by 20-25 days, but overwintering cultivation cannot be carried out; In the southern region, plastic greenhouses are not only used for heat preservation and overwintering cultivation of vegetables and flowers in winter and spring, but also can be replaced with shade nets for shading and cooling in summer and aut...

AI Technical Summary

Problems solved by technology

[0003] The current agricultural plastic greenhouses have the problems of simple structure, low degree of automation, and cannot realize the effect of automatic rolling and unwinding of plastic sheets, automatic irrigation, water conservation, and low earthquake and wind resistance.
