Inverted V-shaped intelligent telescopic fruit tree hail-proof design mechanism

Abstract

The invention aims to provide an inverted V-shaped intelligent telescopic fruit tree hail-proof design mechanism which prevents collapse caused by heavy snow in winter, is effort-saving in stretch and retraction, is long in service life and can intelligently stretch and retract in summer and winter. The mechanism comprises stand columns, a steel wire rope, a polyethylene hail net, an agitating apparatus, pulleys, sliding rings, and bearings. The stand columns can be cement electric poles or creosote impregnated poles; the soil is dug downwards for 1.5-2m for fixing the stand columns; the diameter of each stand column is 100-300mm; the steel wire rope fixes and supports the hail net; steel pipes are connected with the bearings and are fixed and supported by angle steel to form sliding apparatuses; the sliding apparatuses rotate forwards and reversely for stretching and retracting the hail net; the agitating apparatus manually or electrically stretches and retracts the hail net; the sliding rings sleeve the meshes of the hail net and are connected with the steel wire rope to pull the steel wire rope back and forth; the pulleys change the direction of stretching and retracting the steel wire rope to lower the difficulty in stretching and retracting the hail net; the hail net is stretched to be in an inverted V shape; when hail falls down, the inverted V shape enables the hail to slide down from two sides according to a gravity principle, so that fruit trees are prevented from suffering from hail disaster in summer; the hail net is retracted in an effort-saving manner in winter, so that the hail net is prevented from being collapsed by large-area accumulated snow; and therefore, the service life is long.

Description

technical field [0001] The invention relates to an inverted "V" shaped intelligent hail protection mechanism, which belongs to the technical field of agricultural fruit tree protection. [0002] technical background [0003] With the destruction of the natural environment, farmers are facing more and more serious natural disasters. Severe hailstorms in summer have caused farmers to lose their harvest. Farmers are helpless in the face of hail disasters. It is especially important for fruit growers. The price of fruit is high, and the consequences of hailstorms are equivalent to two years of disasters. [0004] The economic loss of farmers after the hail disaster is too great. We combine the needs of farmers, how to prevent disasters and reduce the actual situation of labor force, and develop intelligent pull-out and recycling anti-hail design institutions. Now the left-behind fruit farmers in rural areas are generally older. The old-fashioned hail protection requires manual ...

AI Technical Summary

Problems solved by technology

Now the left-behind fruit farmers in rural areas are generally older. The old-fashioned anti-hail system has to manually go up the high ladder to the hail net every summer. It is dangerous for people and labor-intensive. It takes a lot of manpower to open the hail net.

The cost is also high, and the effect of imitating hail is not good
