Multi-functional hail prevention net frame

Abstract

The invention discloses a multi-functional hail prevention net frame. Vertical rods are ranked in a multi-line and multi-row mode, horizontal iron wires are arranged between top ends of two side rods in the first and last lines, two parallel net hanging iron wires are arranged between the horizontal iron wires between two adjacent rows of the vertical rods, net hanging iron wires are also arranged on two rows of the side rods, pulleys are arranged at the cross positions of the net hanging iron wires and the horizontal iron wires, guide pulleys are arranged at the cross positions of each vertical rod in the first line and the horizontal iron wires, reels are arranged below the guide pulleys, and a plurality of rings are disposed at two edges of a hail prevention net and sequentially ring the net hanging iron wires. The hail prevention net frame is of a curtain type folding and unfolding structure, so that the hail prevention net can be conveniently and freely folded and unfolded by only one person, meanwhile, weathering of the hail prevention net is reduced, and service life of the hail prevention net is prolonged.

Description

technical field [0001] The invention relates to a network frame, more specifically to a multifunctional hailproof network frame. Background technique [0002] For fruit growers, hail is the main natural disaster. In the slightest, it can cause damage to the leaves of fruit trees, damage the fruit surface, and reduce the commodity rate; in severe cases, it can cause leaves and fruits to be broken and fall off, or branches and trunks to rupture. Preventing hail disasters people mainly take the method of man-made weather modification such as anti-hail cannon always, this method can only alleviate disaster loss, can not eliminate the harm to orchard. Building anti-hail nets is a new technology measure to prevent hail in orchards in recent years. It can not only prevent hail, but also prevent strong winds and bird damage. At present, the main method of building anti-hail nets is the whole flat net structure and the ridge structure. The flat net structure is not resistant to stro...

AI Technical Summary

Problems solved by technology

At present, the main method of building anti-hail nets is the whole flat net structure and the ridge structure. The flat net structure is not resistant to strong winds and hail due to the small number of vertical poles, which may easily cause the vertical poles to break and the hail net to collapse. And it is difficult to build, and it is not easy to collect the net; at present, the construction of the ridge structure hailproof net mainly adopts square cement poles and iron poles, covered with single-row trees or double-row masts, and most of them are handmade cement poles, whose tensile and flexural properties are not strong. Moreover, most of them are independently supported and cannot form an overall structure. There are also problems of net collapse and pole collapse after strong wind and hail to varying degrees.
