Adjustable windproof net for orchard

Abstract

The invention discloses an adjustable windproof net for an orchard and belongs to the technical field of windproof nets. The windproof net comprises two first fixed upright posts, a cross beam, a plurality of second fixed upright posts and movable upright posts, wherein the top ends of the first upright posts are connected by the cross beam; the upper ends of the second fixed upright posts are connected with the cross beam; the lower ends of the second fixed upright posts are arranged on the ground; a protecting net is arranged between each movable upright post and the corresponding second fixed upright post; a fixing rope is arranged at the upper ends of the second fixed upright posts; the protecting nets and the upper ends of the movable upright posts are suspended on the fixing rope; a plurality of through holes are formed in the second fixed upright posts and the movable upright posts; pulling ropes are arranged in a mode of penetrating through the through holes; a plurality of fixed pulleys are arranged on the first fixed upright posts; the heights of the fixed pulleys arranged on the two first fixed upright posts are identical; a traction device is arranged on the outer side of one first fixed upright post; and the pulling rope bypasses the two fixed pulleys and the traction device. The adjustable windproof net disclosed by the invention can be folded and unfolded at any time and has the advantages of obvious windproof effect, high stability and easiness in construction.

Description

technical field [0001] The invention relates to the technical field of windproof nets, in particular to an adjustable orchard windproof net. Background technique [0002] In recent years, due to the continuous deterioration of the global natural ecological environment and frequent occurrence of extreme and severe weather conditions, it has seriously affected the production of fruit trees. For example, strong winds in early spring can easily lead to the death of branches of fruit trees; during the growth of new shoots and leaf expansion, strong winds will break young shoots and damage leaves, seriously affecting the accumulation of photosynthetic products in leaves, and seriously affecting the growth of trees and buds in the current year. negative impact. [0003] When the orchard is established, complete shelterbelt facilities can effectively slow down the wind speed, resist the mechanical damage of the trees caused by strong winds, increase the air temperature and humidity...

AI Technical Summary

Problems solved by technology

[0004] At present, due to the need to occupy a certain area of ​​land for the construction of windbreak forests, the reasonable preparation of required trees and shrubs, and the survival of seedlings, etc., the windbreak forests built around newly-built orchards are often incomplete. Practical application results, some orchards do not even consider building windbreaks
