Folding rain shelter for grapes

Abstract

The invention discloses a folding rain shelter for grapes. The folding rain shelter for grapes comprises a plurality of supports which are arranged linearly, and also comprises two guide rails, a plurality of arc-shaped beams the heights of which are sequentially reduced and a deploying and retracting mechanism. The two guide rails are arranged at two sides of the tops of the supports in parallel, a plurality of crossbeams which correspond to the supports one by one are fixed between the two guide rails, the crossbeams are fixedly connected with the supports, the upper surface of each guide rail is provided with a sliding groove, the plurality of arc-shaped beams are sequentially arranged according to the height variation, two ends of each arc-shaped beam are respectively arranged in two sliding grooves, and are respectively in sliding fit with the sliding grooves, and the upper surfaces of the plurality of arc-shaped beams are wrapped by a flexible rain shading layer. In a day with heavy rain, the deploying and retracting mechanism can pull the arc-shaped beams to deploy the flexible rain shading layer for keeping off the rain, and grape vines can be prevented from being damaged by heavy rain; in a sunny day, the deploying and retracting mechanism can pull the arc-shaped beams to retract the flexible rain shading layer, and grapes can be fully irradiated and ventilated; and the folding rain shelter for grapes is good in using effect and high in practicality.

Description

technical field [0001] The invention relates to the technical field of grape planting, in particular to a foldable grape canopy. Background technique [0002] Grapes are the most widely planted and most productive fruit vines in the world. The yield of grapes is determined by many factors. Light and ventilation are important factors that determine the yield and quality of grapes. When growing grapes, trellises are needed to support the vines. The current grape trellises do not have the rainproof function, and the rainstorm will cause serious damage to the grape vines. If it occurs in the young fruit stage or the berry ripe stage, it will seriously affect the grape yield, and the damage is extremely great. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing a foldable grape canopy which has good rainproof effect and does not affect light and ventilation. [0004] Above-mentioned technical probl...

AI Technical Summary

Problems solved by technology

The current grape trellises do not have the function of rainproof. Heavy rain will cause serious damage to the grape vines. If it occurs in the young fruit period or the berry ripening period, it will seriously affect the grape yield, which is extremely harmful.
