Support lever for greenhouse frame and processing equipment and preparation thereof

Abstract

The invention relates to a knighthead for greenhouse frameworks and a processing device thereof and a preparation method, and the knighthead comprises a metal framework layer. The outer part of the metal framework layer is fixedly provided with a reinforced layer; the inner part of the metal framework layer is filled with a core body made of foamed material; the processing device comprises a stander, a power plant, the stander is provided with a stock tank, the power plant is provided with an output shaft, and the axis of the output shaft is positioned inside the stock tank. The preparation method is as follows: the metal framework layer is arranged inside the stock tank, sizing agent is poured inside the stock tank, glass fiber cloth is put inside the stock tank, the metal framework layer is rotated, the glass fiber cloth is coiled on the metal framework layer, a moving cart moves for coiling a PET film, scraps on the film are washed inside a water tank, the PET film is removed, a layer of unsaturated resin is coated on the outer layer so as to have more stable structure, lighter weight and more convenient installation. The winding way of the glass fiber cloth strengthens the intensity and toughness of the reinforced layer and has more corrosion resistance, and the surface resin and the reinforced layer do not easily scratch the film and have long service life.

Description

technical field [0001] The invention relates to a support rod for a greenhouse frame suitable for agricultural cultivation, planting and breeding, and also relates to a processing method and processing equipment for the support rod for a greenhouse frame. Background technique [0002] In recent years, with the promotion of vegetable greenhouses, greenhouses have been widely used in various regions. According to the different natural environmental conditions in various regions and the needs of different crops and different uses, people have made improvements to traditional greenhouses. Due to the limitations of the original economic conditions, traditional greenhouses are generally constructed of cement columns and transverse skeletons, and the skeletons are generally made of bamboo poles. With the development of the economy and the growing trend of greenhouses, framework materials with stronger structures and more convenient construction are required. The material of steel ...

AI Technical Summary

Problems solved by technology

[0005] In the above technical solution, the internal and external solidification of polymer inorganic materials is adopted, which can achieve the purpose of corrosion resistance, low cost, non-scratch, high strength and high toughness to a large extent, but in practice, due to the slurry filling in The purpose of the steel pipe is first to increase the strength, and the second is to prevent rust and corrosion. However, because the slurry is inside the steel pipe and the length of the steel pipe is long, the slurry cannot be condensed and formed in a short time, and it is also difficult to achieve a seamless connection with the steel pipe. Contact, its anti-corrosion effect is poor

If the slurry cannot be condensed and formed within a short period of time, the processing time will be prolonged first, which will have an adverse effect on transportation and installation

At the same time, since the inside and outside are solidified polymer inorganic materials, the weight of the skeleton actually increases, which is particularly unfavorable for the construction of the greenhouse, because the support of the upper film of the greenhouse needs to be supported by multiple support rods. If the support rods are heavy, The weight of itself puts higher requirements on the lower support, which is not in line with the current development trend of growing greenhouses. Larger and larger greenhouses require fewer supports and stronger supports, so it is necessary to try to reduce the upper support. The weight of the support rods can increase the span of the greenhouse more effectively, so the weight of the support rods is obviously of great significance to the greenhouse, especially when sudden weather conditions come, such as freezing rain and snow in the south, basically all The reason for the destruction of greenhouses is that the load-bearing capacity is poor, so reducing its own weight while ensuring strength and toughness has become the focus of expanding the development of greenhouses

[0006] In this technical scheme, the method of adding glass fiber filaments to the slurry is adopted, but adding glass fiber filaments to the slurry can only achieve the effect of increasing toughness to a certain extent, and its bonding degree is poor, and it is completely dependent on the curing of the slurry for bonding , its combination with the steel pipe is poor, and other additives or adhesives need to be added, making the production more complicated

[0007] The technical solution of this patent discloses processing equipment and processing methods, but during the implementation of this equipment, the slurry can only adhere to the surface of the steel pipe, and it cannot be further cleaned. The processed steel pipe has residual slurry on its surface. After the material is cured, the surface is not smooth, and the good use effect cannot be achieved.

Its work efficiency is low
