[0001] This utility model belongs to the field of agricultural planting technology, specifically relating to an agricultural greenhouse support structure. Background Technology

[0002] A greenhouse is a structure made of materials such as bamboo and wood poles, cement poles, lightweight steel pipes, or tubing, forming a frame with columns, tie rods, arches, and compression rods. It is then covered with plastic film to create an arched shed. Greenhouses need to be built in sunny, sheltered, dry, and well-drained locations. A typical plastic greenhouse covers an area of ​​1-3 acres.

[0003] Existing agricultural facilities use greenhouse support structures with fixed-height greenhouse brackets, limiting their support to greenhouses of a single height and restricting the overall usability of the device. While multiple greenhouse brackets can be connected via the insertion of limiting plates and inserts, displacement of these plates or inserts during use can affect the stability of the connection between two brackets, thus impacting the support effectiveness of the brackets. Utility Model Content

[0004] To address the problems mentioned in the background section, this utility model provides an agricultural greenhouse support structure that features both movable adjustment and fixed positioning.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an agricultural greenhouse support structure, including a ground-inserting mechanism, wherein two ground-inserting mechanisms are provided, arranged sequentially from left to right, a limiting plate is fixedly connected to one upper end of the two ground-inserting mechanisms, a positioning component is provided on the limiting plate, a limiting insert plate is fixedly connected to the other upper end of the two ground-inserting mechanisms, a moving block is slidably connected to the side of the limiting plate and the limiting insert plate that are close to each other, a moving component is provided between the moving block and the limiting insert plate and between the moving block and the limiting plate, and a greenhouse bracket is fixedly connected between the two moving blocks;

[0006] The movable component includes a pull rope, and a fixing member is provided on the side wall of the limiting plate and located around the pull rope.

[0007] Preferably, the fixing component includes a U-shaped frame with a threaded hole. A rotating screw is threaded into the threaded hole. A fixed plate is fixedly connected to one end of the rotating screw, and a rubber pad is fixedly connected to the side of the fixed plate away from the rotating screw.

[0008] Preferably, the limiting plate and the limiting plate are both fixedly connected to mounting bases on both sides of the pull rope, and a rotating shaft is rotatably connected between the two mounting bases.

[0009] Preferably, a guide slider is fixedly connected to the side wall of the movable block, and a guide groove is provided on the inner side wall of the limiting plate and the limiting plate at the position corresponding to the guide slider.

[0010] Preferably, the positioning component includes a fixed frame, a positioning post is slidably connected inside the fixed frame, an arc plate is fixedly connected to both sides of the positioning post near the fixed frame, a connecting spring is fixedly connected between the fixed frame and the arc plate, and a positioning groove is provided on the limiting plate and the limiting plate at the position corresponding to the positioning post.

[0011] Preferably, a pull ring is fixedly connected to one end of the positioning post near the fixed frame.

[0012] Preferably, a sliding block is fixedly connected to one end of the arc-shaped plate near the fixed frame, and a sliding groove is provided on the inner sidewall of the fixed frame at the position corresponding to the sliding block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model is equipped with a moving component. Pulling the pull rope moves the component, causing the rotating shaft to rotate. The movement of the pull rope drives the moving block to move, which in turn causes the greenhouse bracket to rise. Once the greenhouse bracket is in contact with the inner top wall of the agricultural greenhouse, pulling the pull rope is stopped, and then the rotating screw is rotated to move along the threaded hole. The rotation of the rotating screw drives the fixed plate to rotate. Once the fixed plate is in contact with the pull rope, the rotation of the rotating screw is stopped. The fixed plate can be used to fix the pull rope, thereby limiting and fixing the moving block and the greenhouse bracket. This facilitates adjusting the height of the greenhouse bracket and makes it easy to support agricultural greenhouses of different heights using the greenhouse bracket.

[0015] 2. This utility model is equipped with a positioning component. When the agricultural greenhouse to be supported is long, the pull ring on the limiting plate near the side wall of one of the greenhouse brackets is held to apply force to move the positioning column. The movement of the positioning column moves the arc plate, which in turn compresses the connecting spring. After the positioning column moves into the fixed frame, the limiting insert plate on the side wall of the other greenhouse bracket is moved and inserted into the limiting plate. Then, the pull ring is released, the connecting spring loses its external force and returns to its original position, moving the arc plate back to its original position. This allows the positioning column to move and insert into the positioning groove. The positioning column and positioning groove can be used to position and fix the limiting insert plate and the limiting plate, thereby limiting and fixing the two greenhouse brackets and ensuring the stability of the connection between the two greenhouse brackets. This ensures the supporting effect of the greenhouse brackets on the agricultural greenhouse. Attached Figure Description

[0025] Please see Figure 1-6 The present invention provides the following technical solution: an agricultural greenhouse support structure, including a ground-inserting mechanism 4, two ground-inserting mechanisms 4 are provided, arranged from left to right, a limiting plate 5 is fixedly connected to one end of the two ground-inserting mechanisms 4, a positioning component 7 is provided on the limiting plate 5, a limiting insert plate 2 is fixedly connected to the other end of the two ground-inserting mechanisms 4, a moving block 3 is slidably connected to the side of the limiting plate 5 and the limiting insert plate 2 that are close to each other, a moving component 6 is provided between the moving block 3 and the limiting insert plate 2 and between the moving block 3 and the limiting plate 5, and a greenhouse bracket 1 is fixedly connected between the two moving blocks 3;

[0026] The moving component 6 includes a pull rope 61, a limiting insert 2, and a fixing member 62 is provided on the side wall of the limiting plate 5 and around the pull rope 61.

[0027] Specifically, the fastener 62 includes a U-shaped frame 621, on which a threaded hole 622 is provided. A rotating screw 623 is threaded into the threaded hole 622. A fixed plate 624 is fixedly connected to one end of the rotating screw 623. A rubber pad 625 is fixedly connected to the side of the fixed plate 624 away from the rotating screw 623.

[0028] By adopting the above technical solution, after pulling the pull rope 61 moves the moving block 3 to a certain height, the rotating screw 623 is rotated to rotate and move along the threaded hole 622. The rotating screw 623 rotates and moves, causing the fixed plate 624 to rotate and move. When the fixed plate 624 moves and fits against the pull rope 61, the rotating screw 623 is stopped. The fixed plate 624 can be used to fix the pull rope 61, and under the action of the rubber pad 625, friction between the fixed plate 624 and the pull rope 61 can be avoided, thereby preventing wear on the pull rope 61.

[0029] Specifically, mounting bases 64 are fixedly connected above the limiting plate 2 and the limiting plate 5, and on both sides of the pull rope 61. A rotating shaft 63 is rotatably connected between the two mounting bases 64.

[0030] By adopting the above technical solution, when the pull rope 61 is pulled to move, the rotating shaft 63 rotates between the two mounting seats 64. Under the rotation of the rotating shaft 63, the movement of the pull rope 61 can be guided, and friction between the pull rope 61 and the limiting plate 2 and the limiting plate 5 can be avoided, thereby preventing wear of the pull rope 61.

[0031] Specifically, a guide slider is fixedly connected to the side wall of the movable block 3, and guide grooves are provided on the inner side walls of the limiting plate 2 and the limiting plate 5 at positions corresponding to the guide slider.

[0032] By adopting the above technical solution, the moving block 3 moves and drives the guide slider to move inside the guide groove. With the sliding cooperation between the guide slider and the guide groove, the movement of the moving block 3 can be guided, thereby improving the stability of the movement of the moving block 3.

[0033] In this embodiment, when supporting the agricultural greenhouse, the entire device is fixed inside the greenhouse using the ground-insertion mechanism 4. Then, the pull rope 61 is pulled to move it, and the rotating shaft 63 rotates between the two mounting seats 64. The movement of the pull rope 61 causes the moving block 3 to move inside the limiting plate 2 and the limiting plate 5. The movement of the moving block 3 causes the greenhouse bracket 1 to rise. When the greenhouse bracket 1 moves and fits against the inner top wall of the agricultural greenhouse, the pull rope 61 is stopped. Then, the rotating screw 623 is rotated to move along the threaded hole 622. The rotation of the rotating screw 623 causes the fixed plate 624 to rotate. When the fixed plate 624 moves and fits against the pull rope 61, the rotation of the rotating screw 623 is stopped. The fixed plate 624 can be used to fix the pull rope 61, thereby limiting and fixing the moving block 3 and the greenhouse bracket 1. This makes it easy to adjust the height of the greenhouse bracket 1, and thus makes it easy to use the greenhouse bracket 1 to support agricultural greenhouses of different heights.

[0034] Example 2

[0035] The difference between this embodiment and Embodiment 1 is that: the positioning component 7 includes a fixed frame 71, a positioning post 72 is slidably connected inside the fixed frame 71, and arc-shaped plates 74 are fixedly connected to both sides of the end of the positioning post 72 near the fixed frame 71. A connecting spring 75 is fixedly connected between the fixed frame 71 and the arc-shaped plates 74. Positioning grooves 73 are provided on the limiting plate 2 and the limiting plate 5 at positions corresponding to the positioning post 72.

[0036] Specifically, a pull ring is fixedly connected to one end of the positioning post 72 near the fixing frame 71.

[0037] By adopting the above technical solution, when it is necessary to move the positioning column 72, the operator can apply force by holding the pull ring to move the positioning column 72, which makes it convenient for the operator to move the positioning column 72.

[0038] Specifically, a sliding block is fixedly connected to one end of the curved plate 74 near the fixed frame 71, and a sliding groove is provided on the inner side wall of the fixed frame 71 at the position corresponding to the sliding block.

[0039] By adopting the above technical solution, the movement of the arc plate 74 drives the sliding block to move inside the sliding groove. With the cooperation of the sliding block and the sliding groove, the movement of the arc plate 74 can be guided, which in turn can guide the movement of the positioning column 72.

[0040] In this embodiment, when the agricultural greenhouse to be supported is long, the pull ring on the limiting plate 5 near one of the greenhouse brackets 1 is held to apply force to move the positioning post 72. The movement of the positioning post 72 moves the arc plate 74, which in turn presses the connecting spring 75. After the positioning post 72 moves into the fixed frame 71, the limiting insert 2 on the side wall of the other greenhouse bracket 1 is moved and inserted into the limiting plate 5. Then the pull ring is released, and the connecting spring 75 returns to its original position after losing external force, moving the arc plate 74 back to its original position. This allows the positioning post 72 to move and insert into the positioning groove 73. The positioning post 72 and the positioning groove 73 can be used to position and fix the limiting insert 2 and the limiting plate 5, thereby limiting and fixing the two greenhouse brackets 1, ensuring the stability of the connection between the two greenhouse brackets 1, and thus ensuring the supporting effect of the greenhouse brackets 1 on the agricultural greenhouse.

[0041] The structure and principle of the ground-inserting mechanism 4, which consists of a base plate, reinforcing components, insert rods, a ground-breaking cone, a receiving hole, a movable rod, a control block, a limiting seat, a tie rod, a movable ball bearing, and a baffle, have been disclosed in Chinese patent application number 202323452132.1, which describes an agricultural greenhouse support structure for agricultural facilities. Its working principle is as follows: A base plate is fixedly connected below the limiting insert plate 2 and the limiting plate 5. Reinforcing components are fixedly installed on both sides of the lower end of the base plate. The reinforcing components include insert rods and movable rods. The insert rods are fixedly connected to both sides of the lower end of the insert rods. The movable rods are movably inserted into the insert rods and also movably inserted into the base plate. A control block is fixedly installed at the upper end of the movable rod, and a control block is fixedly installed at the lower end of the insert rod. Equipped with a soil-breaking cone, multiple insertion rods have storage holes at all four ends on their outer sides that penetrate the interior of the rods. Multiple baffles are fixedly installed on the upper outer side of the insertion rods, with the baffles positioned above the storage holes and having a triangular side profile. Multiple limiting seats 4 are fixedly installed on the lower outer sides of multiple movable rods, arranged in a circular array. A tie rod is rotatably installed on the side end of the limiting seat, located inside the storage hole. A movable ball bearing is rotatably installed on the lower end of the tie rod. During use, when the worker squeezes the movable rod downwards, it can push the bottom of multiple tie rods to slide outwards and unfold, allowing the tie rods to penetrate into the soil outside the insertion rods, thus reinforcing the insertion rods. Because the insertion rods have soil-breaking cones at their bottoms, it is easy to quickly drive the insertion rods into the soil.

[0042] The working principle and usage process of this utility model are as follows: When supporting an agricultural greenhouse, the device is fixed inside the greenhouse using the ground-insertion mechanism 4. Then, the pull rope 61 is pulled to move the device, causing the rotating shaft 63 to rotate between the two mounting seats 64. The movement of the pull rope 61 moves the moving block 3 within the limiting plate 2 and the limiting plate 5. The movement of the moving block 3 causes the greenhouse bracket 1 to rise. Once the greenhouse bracket 1 is in contact with the inner top wall of the greenhouse, the pull rope 61 is stopped. Then, the rotating screw 623 is rotated, moving it along the threaded hole 622. The rotation of the rotating screw 623 causes the fixed plate 624 to rotate. Once the fixed plate 624 is in contact with the pull rope 61, the rotation of the rotating screw 623 is stopped. The fixed plate 624 can be used to fix the pull rope 61, thereby limiting and fixing the moving block 3 and the greenhouse bracket 1, facilitating adjustment of the height of the greenhouse bracket 1, and thus facilitating the use of… The greenhouse bracket 1 supports agricultural greenhouses of different heights. When the agricultural greenhouse to be supported is long, the pull ring on the limiting plate 5 near the side wall of one of the greenhouse brackets 1 is held to apply force to move the positioning column 72. The movement of the positioning column 72 moves the arc plate 74, which in turn presses the connecting spring 75. After the positioning column 72 moves into the fixed frame 71, the limiting insert 2 on the side wall of the other greenhouse bracket 1 is moved and inserted into the limiting plate 5. Then the pull ring is released, and the connecting spring 75 returns to its original position after losing external force, moving the arc plate 74 back to its original position. This allows the positioning column 72 to move and insert into the positioning groove 73. The positioning column 72 and the positioning groove 73 are used to position and fix the limiting insert 2 and the limiting plate 5, thereby limiting and fixing the two greenhouse brackets 1 and ensuring the stability of the connection between the two greenhouse brackets 1. This ensures the supporting effect of the greenhouse bracket 1 on the agricultural greenhouse.
