Description

Technical Field

[0001] This utility model relates to the field of agricultural greenhouse technology, specifically a double-arch, double-film, double-cotton-quilt type greenhouse. Background Technology

[0002] Greenhouses play a vital role in agricultural production, overcoming limitations imposed by natural conditions to some extent, improving agricultural efficiency, optimizing environmental control, and promoting diversified planting. Currently, commonly used greenhouses are mainly staggered double-arch double-film greenhouses and multi-span greenhouses. These types of greenhouses still have certain technical shortcomings, especially in Xinjiang, my country, where their performance disadvantages are particularly pronounced.

[0003] Specifically, staggered double-arch double-film solar greenhouses have low solar utilization efficiency and poor winter insulation performance. Although multi-span greenhouses have the advantage of contiguous space, they are poorly adapted to Xinjiang, have weak overall insulation performance, and are unable to cope with low winter temperatures and drastic temperature differences in spring and autumn; moreover, their complex structure leads to high energy consumption, making them unsuitable for both practicality and economy in southern Xinjiang. Summary of the Invention

[0004] This utility model aims to address the technical deficiencies of existing technologies by providing a double-arch, double-film, double-cotton-quilt greenhouse, thereby solving the technical problem that conventional greenhouses still need to improve in terms of performance.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution:

[0006] The double-arch, double-film, double-quilt greenhouse includes a rear wall, inner trusses, outer trusses, outer PO film, vents, inner PO film, insulation quilts, quilt rolls, motor rotors, slopes, and quilt retaining bars. The inner and outer trusses connect the rear wall to the ground. The outer PO film is attached to the outer truss, and the inner PO film is attached to the inner truss. Ventilations are located at the top and bottom of the outer PO film, and at the bottom of the inner PO film. Insulation quilts are placed on both the outer and inner PO films, with the rear ends of the quilts fixed and the front ends wrapped around the motor rotors to form quilt rolls. The insulation quilts on the outer PO film cover the slope of the rear wall. Quilt retaining bars are connected to the inner and outer trusses, extending upwards above the outer truss.

[0007] Preferably, several membrane slots are provided on the inner truss and the outer truss.

[0008] Preferably, the top of the greenhouse is provided with several vertical planting ropes hanging downwards, and several horizontal planting ropes and several longitudinal planting ropes are connected to the bottom of the several vertical planting ropes.

[0009] Preferably, a roll-up machine slide is provided between the inner truss and the outer truss.

[0010] Preferably, the inner PO film is wound onto the film winding machine.

[0011] Preferably, the device also includes a motor support rod, on which a blanket rolling machine is mounted, and the motor rotating rod is connected to the motor main shaft of the blanket rolling machine.

[0012] Preferably, several longitudinal connecting rods are connected between adjacent inner trusses and between adjacent outer trusses.

[0013] Preferably, an insect-proof net is installed at the ventilation outlet. The installation structure of the insect-proof net includes: several membrane slots are provided on the inner truss and the outer truss; the edges of the insect-proof net and the PO membrane are embedded in the membrane slots and pressed and fixed by spring clips; and the tail screw fixes the edges of the insect-proof net and the PO membrane in the membrane slots.

[0014] Preferably, the installation structure of the film winding machine includes: the film winding machine is fixedly connected to the film winding machine fixing rod, a film winding rod is connected to the output shaft of the film winding machine, and several film fixing clips are provided on the film winding rod.

[0015] Preferably, the greenhouse is equipped with several drip irrigation tapes connected to a water supply pipe, a valve is provided between the drip irrigation tape and the water supply pipe, and the end of the drip irrigation tape is sealed with a plug.

[0016] In the above technical solution, the rear wall is a masonry foundation structure. The inner and outer trusses form a double-arched truss structure. Based on this double-arched truss, double-layered PO film and double-layered insulating blankets are installed to fully ensure the insulation effect. Ventilation vents are used for ventilation. The insulating blankets are rolled onto a motor rotor to form a blanket roll. The motor rotor is connected to a blanket rolling machine, which can roll up or spread the insulating blankets. The rear end of the outer insulating blanket must cover the slope of the rear wall to enhance the insulation effect. Blanket guide bars are used to limit the position of the blanket roll.

[0017] In the preferred technical solution, the PO film is fixed at multiple points using film slots. Planting ropes in the vertical, horizontal, and longitudinal directions can be used for planting operations. A roll-up machine track can be used to set up the roll-up machine. The film roller is used to roll up or spread the inner PO film. A motor support rod is used to install and support the roll-up machine. Longitudinal connecting rods connect adjacent trusses, ensuring the arched support structure of the greenhouse is a unified structure. Insect-proof nets can be installed at the ventilation openings; these nets are secured in the film slots using spring clips and also secured with self-drilling screws. The film roller can be mounted on a film roller fixing rod, which is connected to the roller and rotates with its main shaft, allowing the PO film wound on the film roller to be spread or rolled up; film clamps are used to fix the PO film to the film roller rod. Drip irrigation tape can be installed inside the greenhouse. Irrigation water from the water supply pipeline drips out through the micropores on the drip irrigation tape. The valve located between the drip irrigation tape and the water supply pipeline can control the opening. The plug at the end allows water droplets to be output from the micropores at the bottom of the drip irrigation tape.

[0018] This utility model provides a double-arch, double-film, double-quilt greenhouse. The greenhouse adopts a brick wall double-arch, double-film, double-quilt structure, and is innovatively equipped with three independent roller curtain systems: an inner insulation film, an inner quilt, and an outer quilt. It can be flexibly adjusted according to temperature and light, and has the advantages of structural stability and long service life.

[0019] Moreover, this invention significantly improves the greenhouse's heat preservation performance and adaptability to ambient temperature, precisely meeting the temperature requirements for winter vegetable cultivation in southern Xinjiang and maintaining a stable internal temperature even in low-temperature environments. The invention also offers flexible environmental control; for the nearly 20°C diurnal temperature difference in spring and autumn, the opening and closing of the cotton quilt and the state of the greenhouse film can be flexibly adjusted to precisely control the internal temperature and sunlight intensity, adapting to the environmental needs of different crop growth stages. Furthermore, this invention boasts high space utilization, employing a flower-beam arched design to effectively optimize the greenhouse's spatial layout, expanding the planting area while increasing land utilization and crop yield.
