Novel windproof net for greenhouse

Abstract

The invention relates to a novel windproof net for a greenhouse. A plurality of sawteeth are manufactured on the surface of a connecting sheet, which is positioned below a connecting frame; a pawl is articulated with the upper end of the connecting frame through a hinged shaft; a torsional spring, which is used for realizing the automatic reset of the pawl, is sleeved on the outer edge of the hinged shaft; the lower end of the pawl is aligned to the plurality of sawteeth; and the pawl extends out of the end part of the upper end of the connecting frame and is connected with a stay wire for drawing. In the invention, a windproof net is slidingly mounted on a mulch on the surface of a greenhouse, and the windproof net is lifted through the stay wire connected with two sides of the windproof net, and therefore, functions of wind proofing, dust prevention, snow protection and sun shading are realized; and since people can lift the windproof net through the stay wire when standing on the ground without climbing, the operation is safe and very convenient.

Description

technical field [0001] The invention relates to the field of windproof, dustproof and snowproof equipment for crop planting greenhouses, in particular to a novel windproof net for greenhouses. Background technique [0002] Greenhouse is an auxiliary tool for planting or cultivating crops. Its structure includes back wall, side wall, keel and film covering. Side walls are installed on both sides of the back wall, and keel is installed on the back wall between the two side walls. The keel The top cover is installed with a film. Because the film has a certain degree of permeability, sunlight enters the greenhouse through the film to increase the temperature in the greenhouse, and people can also control the humidity in the greenhouse at the same time, realizing the cultivation of off-season vegetables. In addition to crops In addition, the cultivation of seedlings and other plants can also be carried out in the greenhouse. [0003] In the daily management of greenhouses, windp...

AI Technical Summary

Problems solved by technology

[0003] In the daily management of greenhouses, windproof, dustproof, and snowproof are three very important tasks. Among them, 1. Windproof: Since the film is stretched on the keel through multiple laminating lines, once the wind is strong, it is very easy to Blowing the covering film down or blowing it away will cause disasters to crops or seedlings; 2. Dustproof: When the dust or dust is large, it first blocks the normal transmission of sunlight, and the covering film is also easily damaged; 3. Snow prevention: in the In winter, snowflakes do not have much weight, but once the snow reaches a certain thickness, it will also destroy the coating, resulting in damage to the coating

[0004] In the above item 1, people have developed a windproof net, which is a mesh structure made of nylon and other polymer materials, which can effectively compress the entire film to ensure safety, but because its mesh is very small , blocking the normal transmission of sunlight, which is not conducive to the adjustment of the temperature inside the greenhouse

In the above item 2, when the dust or dust on the coating is large, people first wash it with water, and then use a broom or mop to clean the surface of the coating, but this is very easy to damage the coating and cause unnecessary waste

In the above item 3, when the snow on the surface of the film is thick, people use brooms or push plates to clean it, which may also easily cause damage to the film.
