Problems solved by technology

Using the physical interference method of sending wind force towards the ground by a fan set at a higher place from the ground, mixing the upper and lower layers of air in a small environment, adjusting the local air temperature, and increasing the temperature of the near-surface air, soil or ground plants, especially the plant canopy, To achieve the purpose of preventing crops from being damaged by frost or low temperature and promoting the growth of bud shoots. At present, the frost-proof area of ​​small electric fan models is small (the blowing range of the motor fan is about 10-20 meters), and the current foreign large-scale frost-proof models are generally priced Expensive (the blowing range of the motor fan is about 60-70 meters), it is not suitable for small and medium-sized farmers in China

Embodiment Construction

[0060] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0061] Such as figure 1 Shown is the structural representation of blade in the production technology of frost protection machine blade of the present invention; As figure 2 shown as figure 1 Middle blade every 100mm node cross-sectional view, a kind of production technology of anti-frost machine blade of the present invention, comprises the steps:

[0062] 1) Preparation of glass fiber cloth: composed of the following components by weight percentage: SiO2: 58.0-62.2%; TiO2: 0.3-1.5%; Al2O3: 12.0-14.0%; Fe2O3: 0.2-0.4%; CaO: 22.0-23.0% ; LiO2: 0.1-0.5%; MgO: 2.5-2.8%; WO3: 0-1.0%; Na2O: 0.35%; K2O: 0.15%; CeO2: 0.2-0.5%;

[0063] 2) Preparation of the mold: prepare the blade airfoil model, and process the blade mold with a CNC machine tool;

[0064] 3) Preparation of resin mixture: add activated carbon fiber wave absorbing agent into ep...

Abstract

The invention discloses a frost prevention machine blade production technology. The technology comprises 1, glass fiber cloth preparation, 2, mold preparation, 3, resin mixture preparation, 4, blade laying, 5, curing, 6, cooling and 7, demolding. Through material and airfoil shape improvement, the airfoil-shaped blade has high elasticity modulus, high product rigidity, light weight, enough wind power, a wind speed of 1.5m / s or more in a covering range, a winding range of about 40-60m, a simple structure, small investment and high efficiency and satisfies requirements of large, small and medium farmers.

Description

technical field [0001] The invention belongs to the technical field of components of glass fibers or filaments, and in particular relates to a production process for frost-proof machine blades. Background technique [0002] In early spring and late autumn, due to the frequent intrusion of cold air, the temperature drops sharply, especially in clear and windless nights or early mornings, when radiation heat dissipation increases, the temperature of the ground and plant surfaces drops rapidly, and when the plant body temperature drops below 0°C, it will Suffering from frost damage, the cells in the body will dehydrate and freeze, which will damage the plant tissue. After sunset, the vertical direction of the garden will produce a temperature inversion phenomenon in which the temperature of the upper air is significantly higher than that of the lower layer. When the temperature is 5-10°C higher, after sunrise, the opposite temperature inversion phenomenon will occur. Using the...
