Description

Technical Field

[0001] This invention relates to the field of greenhouse planting equipment technology, and in particular to a quick-assembly and disassembly support device for greenhouse vegetable insect-proof netting. Background Technology

[0002] In the process of greenhouse vegetable cultivation, in order to prevent pests such as aphids, whiteflies, and diamondback moths from attacking vegetable plants, and to avoid fruit and vegetable residues and soil pollution caused by excessive pesticide spraying, insect-proof nets are usually built inside or outside the greenhouse to achieve green pest control through physical barriers and ensure the quality of vegetable cultivation.

[0003] Currently, traditional greenhouse insect-proof netting support structures are mostly fixed welded frames or tied supports, with a fixed and non-adjustable overall structure, resulting in many defects. First, the overall size of traditional supports is fixed, making it impossible to flexibly adapt to the actual span of the greenhouse and the width of the planting beds, resulting in poor versatility. Second, the installation and dismantling process of the supports is cumbersome, requiring the use of wrenches, ropes, and other tools, resulting in high manual labor intensity and long assembly and disassembly times, which is not conducive to rapid seasonal installation and storage. Third, traditional supports are mostly fixed structures, unable to be flexibly moved, which can easily cause obstruction and hinder operations during greenhouse land preparation, vegetable transplanting, and ventilation and lighting adjustments. Fourth, traditional supports cannot be compressed or disassembled for storage, occupying a large amount of storage space and making transportation and storage extremely inconvenient.

[0004] Therefore, in view of the technical defects of existing insect-proof net support devices, such as inconvenience in disassembly and assembly, inability to extend and adjust, poor mobility, and large storage space occupation, this invention proposes a greenhouse vegetable insect-proof net support device that can be quickly disassembled and assembled, extended and adjusted, and flexibly moved, so as to meet the needs of large-scale and refined greenhouse vegetable cultivation. Summary of the Invention

[0005] The purpose of this invention is to provide a quick-assembly and disassembly support device for greenhouse vegetable insect-proof nets, so as to solve the technical problems of traditional insect-proof net supports in the prior art, such as fixed and unadjustable supports, cumbersome assembly and disassembly, inconvenient movement, large storage volume, and weak versatility.

[0006] A quick-assembly and disassembly support device for greenhouse vegetable insect-proof netting includes an insect-proof netting, at least two sets of movable column assemblies, and a telescopic scissor mesh frame. The movable column assembly includes a column body and a base with locking casters; the base is fixedly installed at the bottom end of the column body, and the base is equipped with casters with brake locking function; a strip-shaped perforated plate is fixedly provided on the bottom side wall of the column body, and the strip-shaped perforated plate has an elongated sliding groove along the height direction of the column body; a connecting plate is fixedly provided on the top side wall of the column body. The retractable scissor grid frame comprises multiple sets of interlocking grid rods. Both ends of the scissor grid frame are respectively assembled with corresponding movable column assemblies. The upper end of the scissor grid frame is hinged to the connecting plate on the upper part of the column body by rotating screws. The lower end of the scissor grid frame is slidably assembled in the elongated groove of the perforated plate and locked and positioned by passing a butterfly bolt through the perforated plate. The scissor mesh frame can be stretched and compressed. The insect net is directly fixed to the scissor mesh frame or placed on top of the scissor mesh frame, with the scissor mesh frame providing support for the insect net.

[0007] Furthermore, the scissor grid frame is a detachable structure, which is composed of multiple scissor units spliced ​​together. Adjacent scissor units are detachably connected by hinge pins, which can increase or decrease the number of scissor units according to the actual span of the greenhouse, thereby expanding or reducing the length.

[0008] Furthermore, the butterfly bolt is located at the lower end of the scissor grid frame. The butterfly bolt is adapted to be installed in the elongated groove of the strip plate. The butterfly bolt can slide up and down along the groove. Tightening the butterfly bolt can lock it in place, and loosening the butterfly bolt allows the scissor grid frame to extend and retract freely.

[0009] Furthermore, at least two sets of the movable column assemblies are provided, respectively arranged at both ends of the scissor grid frame, and multiple sets of movable column assemblies together provide multi-point support for the stretched and unfolded scissor grid frame.

[0010] Furthermore, the base is a horizontally arranged beam structure, the casters are installed at both ends of the beam, and the casters are equipped with brake components. When the casters are unlocked, the entire device can be moved. When the casters are braked and locked, the placement position of the entire device is fixed.

[0011] Furthermore, the grid members of the scissor grid frame are rectangular frame members, and multiple members are cross-hinged to form diamond-shaped telescopic units. All diamond-shaped telescopic units are sequentially hinged end to end to form an overall telescopic frame.

[0012] Furthermore, the hinge pins between the scissor units of the scissor grid frame are quick-release pins. Pulling out the quick-release pins allows the scissor grid frame to be disassembled, enabling the device to be disassembled, stored, and transported.

[0013] The beneficial effects of this invention are as follows: 1. This invention features a telescopic scissor mesh frame, which, in conjunction with the sliding locking structure of the perforated plate on the column body, allows for rapid stretching and compression of the mesh frame without the need for specialized tools. This significantly simplifies the process of laying and storing insect netting, reduces manual labor intensity, and greatly improves assembly and disassembly efficiency.

[0014] 2. This invention uses a movable column assembly with locking casters, and the whole device can be moved flexibly. The placement of the support device can be adjusted according to the needs of greenhouse planting operations and the growth position of vegetables, avoiding obstruction of ventilation and light. It is suitable for various operation scenarios such as greenhouse land preparation, transplanting, and harvesting, and is more practical.

[0015] 3. The scissor grid frame adopts a multi-segment splicable structure, which can freely increase or decrease the number of units according to the greenhouse span and planting bed width, making it suitable for use in greenhouses of different specifications. It is highly versatile. At the same time, the compressible and disassembleable structural design greatly reduces the storage volume and reduces the difficulty of storage and transportation.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] In the description of the embodiments of the present invention, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is usually placed during use, they are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0021] Furthermore, the use of terms such as "horizontal," "vertical," and "sag" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0022] A quick-assembly and disassembly support device for greenhouse vegetable insect-proof netting includes an insect-proof netting, at least two sets of movable column assemblies 100, and a telescopic scissor mesh frame 200.

[0023] The movable column assembly 100 includes a column body 101 and a base 102 with locking casters 103. The base 102 is fixedly installed at the bottom end of the column body 101, and the base 102 is equipped with casters 103 with brake locking function. A strip-shaped perforated plate 104 is fixedly provided on the bottom side wall of the column body 101. The strip-shaped perforated plate 104 has an elongated groove along the height direction of the column body 101. A connecting plate 105 is fixedly provided on the top side wall of the column body 101.

[0024] Specifically, the base 102 is a horizontally arranged beam structure, and casters 103 are installed at both ends of the beam. The casters 103 are equipped with brake components. When the casters 103 are unlocked, the entire device can be moved in any direction to adapt to the insect-proof netting construction needs of different planting areas in the greenhouse. After the casters 103 are braked and locked, the placement position of the entire device can be quickly fixed to prevent the device from shifting or shaking during use and to ensure the stability of the support.

[0025] The telescopic scissor grid frame 200 includes multiple sets of cross-hinged grid rods. Both ends of the scissor grid frame 200 are respectively assembled with corresponding movable column assemblies 100. The upper end of the scissor grid frame 200 is hinged to the connecting plate 105 on the upper part of the column body 101 by rotating screws, so that the upper end of the scissor grid frame 200 can rotate freely to adapt to the angle changes during the telescopic process. The lower end of the scissor grid frame 200 is slidably assembled in the elongated groove of the perforated plate 104, and the lower end of the scissor grid frame 200 is locked and positioned by passing through the perforated plate 104 with a wing bolt 201.

[0026] The wing bolt 201 is located at the lower end of the scissor grid frame 200. The wing bolt 201 is adapted to be installed in the long strip groove of the strip plate 104. The wing bolt 201 can slide freely up and down along the groove. The operator can lock the lower position by manually tightening the wing bolt 201 without the need for tools, thus fixing the unfolded size of the scissor grid frame 200. By manually loosening the wing bolt 201, the scissor grid frame 200 can be freely extended and retracted, making the operation convenient and efficient.

[0027] In this embodiment, at least two sets of movable column assemblies 100 are provided, respectively arranged at both ends of the scissor grid frame 200. Multiple sets of movable column assemblies 100 cooperate to form a multi-point support structure, which effectively improves the overall stability of the scissor grid frame 200 after unfolding and avoids deformation and tilting of the support due to the weight of the insect net and the action of wind.

[0028] The scissor mesh frame 200 has rectangular frame members. Multiple members are cross-hinged to form diamond-shaped telescopic units. All diamond-shaped telescopic units are sequentially hinged end to end to form an overall telescopic frame. This structure has uniform stress distribution, smooth telescopic movement without jamming, and high flatness after unfolding. It can stably support the insect-proof net, ensuring that the insect-proof net is laid flat and without wrinkles, thus improving the insect-proof effect.

[0029] Meanwhile, the scissor grid frame 200 features a detachable structure, composed of multiple scissor units. Adjacent scissor units are detachably connected by hinged pins, which are quick-release pins. Workers can easily disassemble the scissor units by pulling out the quick-release pins. The number of scissor units can be freely increased or decreased according to the actual span of the greenhouse and the width of the planting beds, allowing for flexible expansion and reduction of the device's length, making it suitable for greenhouses of different sizes. When not in use, the scissor grid frame 200 can be completely compressed, folded, and disassembled for storage, greatly reducing its storage volume and saving warehouse space, while also facilitating short- and long-distance transportation.

[0030] The specific usage method of this device is as follows: First, assemble the corresponding number of scissor lift units according to the width of the greenhouse planting area to complete the scissor lift grid frame 200; move two or more sets of movable column components 100 to the designated position and lock the column position with the locking casters 103; manually stretch the scissor lift grid frame 200 to the required span and height, adjust the lower end position along the groove of the perforated plate 104, and after adjustment, manually tighten the wing bolts 201 to complete the locking and positioning; finally, fix the insect net directly on the scissor lift grid frame 200 or place it on top of the grid frame to complete the rapid construction of the insect net.

[0031] When disassembly and storage are required, simply loosen the wing bolt 201 and compress the scissor grid frame 200 to complete the folding. If storage is required, the quick-release pin can be pulled out to separate the scissor unit, and the casters 103 can be unlocked to move and store the entire device. No professional tools are required throughout the process, making disassembly and assembly convenient and efficient.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
