Description

Technical Field

[0001] This utility model relates to the field of agricultural planting equipment technology, specifically to a quick-release agricultural greenhouse frame connection device. Background Technology

[0002] As a crucial facility in modern agricultural production, the efficiency of installing and dismantling the frame structure of agricultural greenhouses directly impacts the construction cycle, maintenance costs, and reusability of the greenhouse. Traditional greenhouse frame installation typically uses welding for fixation. While this technology ensures the stability of the frame structure, it also introduces several problems:

[0003] Firstly, during the installation process, welding operations require professional personnel to carry welding equipment on-site, which is greatly constrained by environmental factors such as site power supply and weather. Furthermore, the welding points need to be precisely aligned, resulting in a long construction time for a single greenhouse, making it difficult to meet the needs of agricultural production for timely greenhouse construction. In addition, welding is a permanent fixed structure, and when the greenhouse needs to be dismantled and relocated later (such as for land rotation or land transfer) or when the frame needs to be repaired or replaced, it must be disassembled by cutting. This is not only cumbersome and time-consuming, but also prone to damaging the frame pipes, significantly reducing the reuse rate of the frame and increasing the equipment replacement cost for growers. Therefore, we propose a quick-release agricultural greenhouse frame connection device to solve the above problems. Utility Model Content

A second screw is threadedly connected to the surface of the support plate, and a limiting plate is fixedly mounted on the top of the second screw.

[0008] A folded plate is hinged to the top of both sides of the rectangular frame. The side of the folded plate away from the rectangular frame can be laid flat on the support plate, and its end is constructed with a U-shaped notch, which is adapted to the second screw.

[0009] A support plate is provided on both sides of the rectangular frame. A mounting block is fixed on the top of the support plate. A connecting cylinder is fixed on the side of the mounting block near the rectangular frame. The first screw is threadedly connected to the connecting cylinder.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] This application provides a quick-release agricultural greenhouse frame connection device, mainly to solve the problem that in the existing technology, welding operations require professional personnel to carry welding equipment on-site during the installation process, which is greatly restricted by environmental factors such as site power supply and weather. Furthermore, the welding points need to be precisely aligned, resulting in a long time consumption for building a single greenhouse, making it difficult to meet the needs of timely greenhouse construction in agricultural production. The following technical solution is provided, which will be discussed in conjunction with... Figure 1 - Figure 4 Please provide a detailed explanation:

[0025] A quick-release agricultural greenhouse frame connection device includes:

[0026] A rectangular frame 1, wherein a first screw 2 is threadedly connected to the middle of both ends of the rectangular frame 1;

[0027] A connecting plate 3 is detachably disposed in the middle of the rectangular frame 1. Support plates 4 are fixedly disposed on the upper sides of both sides of the connecting plate 3. A second screw 5 is threadedly connected to the surface of the support plate 4. A limiting plate 6 is fixedly disposed on the top of the second screw 5.

[0028] The folded plate 7 is hinged to the top of both sides of the rectangular frame 1. The side of the folded plate 7 away from the rectangular frame 1 can be laid flat on the support plate 4, and its end is constructed with a U-shaped notch 701. The U-shaped notch 701 is adapted to the second screw 5.

[0029] Support plate 8 is provided on both sides of the rectangular frame 1. Mounting block 9 is fixedly provided on the top of the support plate 8. Connecting cylinder 901 is fixedly provided on the side of the mounting block 9 near the rectangular frame 1. The first screw 2 is threadedly connected to the connecting cylinder 901. Insert pins 802 are fixedly provided on both sides of the bottom of the support plate 8.

[0030] It also includes a connecting rod 10, which is detachably disposed between adjacent mounting blocks 9. Sleeves 902 are fixed on both sides of the mounting blocks 9, and the two ends of the connecting rod 10 are slidably inserted into the sleeves 902.

[0031] Workflow Description:

[0032] Installation process:

[0033] The first step is to slide the two ends of the connecting rod 10 into the sleeves 902 on both sides of the adjacent mounting block 9, so that multiple support plates 8 are connected into a horizontal overall frame through the connecting rod 10, ensuring that the devices installed laterally are on the same horizontal line, laying the foundation for the regularity of the greenhouse frame.

[0034] The second step is to place the support plates 8, which have been horizontally connected, one by one along the direction of the field ridges. Then, use external force to vertically insert the stakes 802 on both sides of the bottom of the support plate 8 into the ground until the top of the support plate 8 is horizontal and stable, thus completing the vertical support installation of the device.

[0035] The third step is to align the first screw 2 at the middle of both ends of the rectangular frame 1 with the connecting cylinder 901 on the top mounting block 9 of the support plate 8, and rotate the first screw 2 to make it threadedly engage with the connecting cylinder 901 until the rectangular frame 1 is tightly connected to the mounting block 9. At this time, multiple rectangular frames 1 and the support plate 8 together form the main support frame of the greenhouse skeleton.

[0036] Fourth, place the greenhouse frame pipes on the arc-shaped top of the connecting plate 3 in the middle of the rectangular frame 1. After ensuring that the pipes are aligned, flip the folding plate 7 so that the side away from the rectangular frame 1 is laid flat on the support plates 4 on both sides of the connecting plate 3, and the U-shaped notch at the end of the folding plate 7 is fully adapted to the second screw 5 on the support plate 4. Finally, rotate the second screw 5 clockwise to move the top limiting plate 6 down until the limiting plate 6 is in close contact with the top of the folding plate 7. Repeat this step to fix all the greenhouse frame pipes in sequence, and the installation of the entire greenhouse frame will be completed.

[0037] Disassembly process

[0038] When the greenhouse needs to be disassembled or moved, first rotate the second screw 5 in the opposite direction to move the limiting plate 6 upward and disengage it from the folding plate 7, then fold and retract the folding plate 7; after removing the frame pipes, rotate the first screw 2 in the opposite direction to separate the rectangular frame 1 from the support plate 8, pull out the support plate 8 from the ground, and pull out the connecting rod 10 between the adjacent mounting blocks 9, so that each component can be disassembled and stored, achieving quick disassembly.

[0039] The device uses modular components such as a rectangular frame 1, a support plate 8, and a connecting plate 3. It is fixed by threaded connection (first screw 2 and connecting cylinder 901, second screw 5 and support plate 4) and hinge (folded plate 7 and rectangular frame 1). No welding is required during installation. The modular components are quickly connected by threads and hinges, which improves installation efficiency. At the same time, each component is detachable and can be disassembled without cutting, avoiding damage to the skeleton pipe caused by traditional welding and disassembly, and greatly improving the reusability of the skeleton and connecting device.

[0040] like Figure 1 As shown, in some embodiments, the top of the connecting plate 3 is arc-shaped. More specifically, the arc-shaped design of the top of the connecting plate 3 allows the greenhouse film to adhere to its surface and form a smooth transition, avoiding local squeezing and friction at the contact point between the film and the connecting plate 3 due to sharp edges, reducing the risk of film damage and extending the service life of the film. At the same time, the arc-shaped structure can guide rainwater to slide down quickly along the curved surface, preventing rainwater from accumulating on the top and around the connecting plate 3 and forming water accumulation, avoiding water seepage that could damage the film or cause additional load to the frame due to increased weight, thus ensuring the overall stability of the greenhouse.

[0041] like Figure 3As shown, in some embodiments, a rectangular groove 101 is provided in the middle of the rectangular frame 1, and the connecting plate 3 is slidably embedded in the rectangular groove 101. More specifically, the rectangular groove 101 in the middle of the rectangular frame 1 and the connecting plate 3 form a precise fitting structure. During installation, the connecting plate 3 can be directly slid into the rectangular groove 101 without repeated alignment, achieving rapid positioning and significantly shortening the installation time. During disassembly, the connecting plate 3 only needs to be slid out along the rectangular groove 101 without disassembling other parts, making the operation simple. At the same time, the rectangular groove 101 limits the connecting plate 3 to prevent it from shifting after installation, ensuring the stability of the subsequent frame fixation, and taking into account both rapid disassembly and assembly and structural stability.

[0042] like Figure 4 As shown, in some embodiments, the surface of the support plate 8 is provided with rectangular channels 801 at equal intervals. More specifically, the support plate 8 is provided with rectangular channels 801 at equal intervals. Under the premise of ensuring structural strength, the amount of material used is greatly reduced and its own weight is significantly reduced. The lightweight design makes it easier to carry the support plate 8 and easier to control the verticality when inserting it into the ground, reducing the difficulty of installation. At the same time, the weight reduction does not weaken the support performance. The regular arrangement of the rectangular channels 801 can distribute the force and ensure the stable support of the support plate 8 for the greenhouse frame, taking into account both convenience and practicality.

[0043] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
