Agricultural wind-resistant protective fence

Abstract

The invention discloses an agricultural wind-resistant protective fence, and belongs to the technical field of agricultural cultivation protection. The agricultural wind-resistant protective fence comprises a plurality of pile bodies and a wind blocking structure arranged between two adjacent pile bodies. The wind blocking structure comprises a wind blocking plate, a rotating shaft and a guide plate, the wind blocking plate is vertically arranged between the two pile bodies, and the middle of the wind blocking plate is rotationally connected with the pile bodies through the rotating shaft; the lower end of the guide plate is connected with the lower parts of the pile bodies, and the upper end of the guide plate inclines to the pile bodies and extends upwards; and when the wind blocking plate rotates by a certain angle under the action of wind power, an obliquely-upward wind dispelling channel is formed between the wind blocking plate and the guide plate. According to the agricultural wind-resistant protective device, crops can be protected, and the influence of wind and sand on the crops is prevented; and the agricultural wind-resistant protective device can be suitable for a strong wind environment, is high in wind resistance and is more stable.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding protection, and in particular relates to an agricultural wind-resistant protective fence. Background technique [0002] Harm to crops includes mechanical damage and physiological damage. Strong winds cause blades to be mechanically scratched, crops to fall, trees to break, and flowers and fruits to fall, affecting yields. Strong winds also cause wind erosion of soil, movement of sand dunes, and damage to farmland. Blindly cultivate wasteland in arid areas, the wind will lead to desertification of the land. Strong winds and snowstorms in pastoral areas can disperse herds and aggravate frost damage. Local winds, such as tidal winds with high salt content from the sea, high temperature and low humidity foehn and dry hot winds, all seriously affect the flowering and fruit setting of fruit trees and the grain filling of cereal crops. The strong winds in the early spring in the north o...

AI Technical Summary

Problems solved by technology

The strong wind in early spring in the north often causes wind damage to trees, and partial crown and eccentric phenomena appear. Partial crown will bring difficulties to tree pruning and affect the function of trees; eccentric trees are prone to frost damage and sunburn, affecting the normal operation development
