Description

Technical Field

[0001] This utility model relates to the field of hail-proof and rainproof shed film technology, specifically agricultural hail-proof and rainproof shed film. Background Technology

[0002] Greenhouse film refers to special plastic film used in the construction of facility agriculture production. It is of great significance to the growth, yield and income of greenhouse crops. In agricultural production, crops often need to be protected from rain, birds and frost to improve the quality of crops. Generally, rain protection is achieved by radiating rain-proof greenhouse film on the outside of the crops.

[0003] Existing technologies, such as CN219612686U, describe an agricultural rain-proof and windproof greenhouse film. The upper film and the reinforcing net are composed of different proportions depending on the width of the bottom. This ensures that while enhancing the stability, the film allows for rapid airflow and prevents rain leakage, making it suitable for planting various plants.

[0004] However, this greenhouse film still has some shortcomings in its use: 1. The greenhouse film has poor wind resistance and hail protection capabilities. It is easily damaged and cannot effectively protect crops from harm, which leads to a decrease in crop yield and quality. In addition, the greenhouse film does not facilitate rapid ventilation inside the greenhouse.

[0005] 2. The greenhouse film is not convenient for heat preservation, especially in cold seasons or regions. Relying solely on the upper and lower films for protection may cause crops to suffer from low-temperature freezing damage, thereby affecting their normal growth and yield. Utility Model Content

[0006] The purpose of this utility model is to provide an agricultural hail and rainproof greenhouse film to solve the problems mentioned in the background art, such as the film's weak wind resistance and hail protection, its susceptibility to damage, and its inability to effectively protect crops from harm, which leads to a decrease in crop yield and quality. Furthermore, the film is not conducive to rapid ventilation inside the greenhouse, and it is not convenient for heat preservation, especially in cold seasons or regions. Relying solely on the upper and lower films for protection may result in low-temperature freezing damage to crops, thereby affecting their normal growth and yield.

[0007] To achieve the above objectives, this utility model provides the following technical solution: Agricultural hail and rainproof shed film includes an arc-shaped support beam. The top of the arc-shaped support beam abuts against a protective shed fabric. A bearing rod is provided on the side of the protective shed fabric. A first positioning block is fixedly connected to the side of the bearing rod. A first slot is opened on the side of the first positioning block. A fixing rod is engaged in the first slot. The fixing rod is located at the end of the protective shed fabric. A connecting ring is fixedly connected to the end of the protective shed fabric. The connecting ring is engaged with the fixing rod. The protective shed fabric consists of three layers: upper, middle, and lower. The two sides of the middle layer are fixedly connected to the upper and lower layers respectively through double-sided coating. The protective shed fabric is made of HDPE polyethylene and UV anti-aging and anti-ultraviolet additives.

[0008] As a preferred embodiment of this utility model, the bottom of the arc-shaped support beam is provided with a heat-insulating film, the bottom of the heat-insulating film is provided with a positioning rod, the side of the positioning rod is fixedly connected with an installation hook, the end of the heat-insulating film is fixedly connected with a winding rod, the side of the bearing rod is fixedly connected with a second positioning block, the side of the second positioning block is provided with a second slot, and the winding rod is engaged with the second slot.

[0009] As a preferred embodiment of this utility model, a fixing bolt is provided at the bottom of the positioning rod. The fixing bolt passes through the positioning rod and the insulation film and extends into the arc-shaped support beam. The fixing bolt is threadedly connected to the positioning rod.

[0010] As a preferred embodiment of this utility model, a support rod is fixedly connected to the bottom of the arc-shaped support beam, and a ground spike is fixedly connected to the bottom of the support rod. The arc-shaped support beam, the support rod, and the ground spike are integrated into one piece, and the arc-shaped support beam, the support rod, and the ground spike are all made of stainless steel.

[0011] As a preferred embodiment of this utility model, the bottom of the bearing rod is fixedly connected to a mounting base plate, and the bottom of the mounting base plate is provided with anti-slip texture.

[0012] As a preferred embodiment of this utility model, two winding rods are provided, and the two winding rods are respectively located at both ends of the insulation film.

[0013] As a preferred embodiment of this utility model, the mounting hooks are provided in two sets, and the two sets of mounting hooks are positioned opposite each other.

[0014] As a preferred embodiment of this utility model, the protective canopy is located on top of the insulation film, and the insulation film is made of polyvinyl chloride.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, by using a protective tarpaulin, connecting ring, fixing rod, and first positioning block in combination, multiple protective functions of the hail-proof and rain-proof greenhouse film are achieved. The protective tarpaulin enhances the wind resistance and hail resistance of the greenhouse film, effectively resisting damage to crops from severe weather and improving crop yield and quality. The protective tarpaulin is composed of an upper film, a middle film, and a lower film, which not only enhances the waterproof performance of the greenhouse film but also improves its puncture resistance. The combined use of the connecting ring, fixing rod, and first positioning block allows the greenhouse film to be quickly gathered together, facilitating rapid ventilation inside the greenhouse and improving the practicality and convenience of the greenhouse film.

[0016] 2. In this utility model, the combined use of an insulation film, positioning rod, winding rod, second positioning block, arc-shaped support beam, and installation hook further enhances the insulation effect of crops, making it particularly suitable for cold seasons or nighttime insulation needs. The insulation film effectively reduces heat loss inside the greenhouse, providing a warm growing environment for crops. The combined use of the positioning rod, winding rod, installation hook, and second positioning block enables rapid unfolding and rewinding of the insulation film, facilitating flexible adjustments to insulation measures according to weather changes. It also facilitates the maintenance and management of the greenhouse film. The arc-shaped support beam not only enhances the structural stability of the greenhouse but also optimizes the light distribution inside, allowing crops to receive sunlight evenly, promoting photosynthesis, and further improving crop yield and quality.
