Description

Technical Field

[0001] This invention relates to the field of agricultural facility engineering technology, specifically to a structure for constructing an insulated greenhouse for agricultural planting. Background Technology

[0002] Agricultural greenhouses are widely used facilities in modern agricultural production. By creating a controlled local climate environment, they effectively extend the crop growth cycle and improve crop yield and quality. The stability of the greenhouse structure, its insulation performance, and the ease of management directly affect the economic benefits of agricultural production.

[0003] Existing agricultural greenhouses typically consist of a ground surface, a supporting frame, a greenhouse film, and a rollable insulation blanket. The supporting frame is usually installed on the ground using methods such as inserting it into the ground or fixing it to a foundation, and the greenhouse film is then placed on top to form an enclosed space. To regulate the temperature inside the greenhouse, an insulation blanket is usually installed on the roof, and a motor-driven roller is used to unfold and roll up the blanket. In addition, when the humidity inside the greenhouse is high, condensation easily forms on the inner surface of the insulation blanket. Current technology either allows it to drip naturally or uses simple drainage channels to collect it.

[0004] However, the aforementioned existing technologies have several shortcomings. First, the installation of the support structure is often not secure enough, especially on soft ground, where it is prone to settling or tilting, affecting overall stability; the installation process is also cumbersome and inefficient. Second, the support structure of the insulation blanket's roll-up system is complex and has poor linkage with the support frame, making it prone to shifting or jamming during long-term use. Furthermore, the methods for handling condensate are inefficient, failing to effectively scrape and collect it; dripping water can adversely affect crop growth and exacerbate humidity inside the greenhouse. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a structure for building an insulated greenhouse for agricultural planting, so as to solve the technical problems of low installation efficiency and poor stability of greenhouse support structure, unstable operation of insulation blanket rolling system and complex support.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a structure for constructing an insulated greenhouse for agricultural planting, comprising a ground, a greenhouse film, and an insulation blanket, and further comprising: multiple supporting devices, disposed on the top of the ground and forming a rectangular frame, each supporting device comprising an outer sleeve and a fixing rod, the fixing rod penetrating the outer sleeve and having a pointed bottom for insertion into the ground, the fixing rod having a connecting ring and a pair of nailing plates, the nailing plates extending to the outside through guide grooves opened on the outer sleeve, and the fixing rod moving downward by striking the nailing plates; a support frame. A mounting device is installed on top of the support device and fixed by the fixing rod and the clamping plate. The clamping plate is connected to the top of the fixing rod by the clamping rod and bolts. A winding device includes a winding shaft, a winding motor and a mounting plate. The winding shaft is located on both sides of the insulation blanket and is rotatably connected to the mounting plate. The winding motor drives the winding shaft to wind up or unwind the insulation blanket. The mounting plate is connected to the ground by a telescopic rod and a mounting component. A condensate collection device includes a mounting frame, a collection belt and a rubber scraper. The rubber scraper is in contact with the surface of the insulation blanket and is used to scrape condensate to the collection belt.

[0007] The invention is further configured such that a limiting member is provided outside the outer sleeve to limit the nail plate, so that the bottom part of the fixing rod is exposed outside the outer sleeve during the initial installation.

[0008] The present invention is further configured such that a connecting plate is provided around the top of the fixing rod, and a groove is provided on the top of the clamping plate. Bolt holes are provided at the bottom of the groove and on the connecting plate respectively, and the clamping plate and the fixing rod are fixed by bolt connection.

[0009] The present invention is further configured such that the plurality of support devices on the short side of the rectangular frame gradually decrease in height towards both sides with the two middle support devices as a reference, forming a trapezoidal structure when viewed from the side.

[0010] The invention is further configured to include a connecting crossbar and a connector. The connecting crossbar is disposed on the top of the fixed rod of the support device serving as a reference and is fixed by an opening and a limiting shaft. The connector is disposed on the top of the connecting crossbar and connected to the middle section of the insulation blanket.

[0011] The invention is further configured such that the mounting plate has a groove, the mounting frame slides within the groove by a slider, and the collecting belt is provided at the bottom of the mounting frame.

[0012] The present invention is further configured such that the mounting plate is provided with a first locking block and a second locking block, which are used to limit the mounting frame and prevent excessive displacement.

[0013] The invention is further configured such that the telescopic rod is rotatably connected to the ground via the mounting member, and rotates as the winding shaft winds up or unwinds to support the mounting plate.

[0014] The invention is further configured such that the rubber scraper is disposed on one side of the top of the connector and is in contact with the surface of the insulation blanket.

[0015] The present invention is further configured such that the support frame is provided with a limiting hole for engaging with the top of the fixing rod, and is limited and fixed by the clamping plate.

[0016] In summary, the present invention has the following main beneficial effects: This invention significantly improves overall insulation performance by forming a stable air insulation layer between the greenhouse film and the insulation blanket, fully utilizing the physical properties of the insulation material. Simultaneously, its unique support device uses hammering nails to move the fixing rod downwards and locking it with a clamping plate, enabling rapid and secure installation of the support frame and flexible height adjustment. This effectively overcomes the shortcomings of traditional greenhouse installations, such as cumbersome installation and poor stability. Furthermore, the integrated high-efficiency condensate collection and scraping mechanism effectively avoids the adverse effects of condensate on crops, thus achieving overall greenhouse structural stability, uniform and reliable insulation, and environmental control.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of the present invention will now be described.

[0021] A type of insulated greenhouse structure for agricultural planting, such as Figure 1-8 As shown, it mainly includes the ground 1, greenhouse film 2, insulation blanket 3, support device 7, winding device and condensate collection device.

[0022] Multiple support devices 7 are provided, installed on the top of the ground 1, forming a rectangular structural frame. The long side of this rectangular frame is designated as the row, and the short side as the column. Each support device 7 specifically includes a vertically arranged outer sleeve 15 and a fixing rod 18. The fixing rod 18 penetrates the internal cavity of the outer sleeve 15, and its bottom is machined into a sharp shape for easy insertion into the ground 1. A connecting ring 16 is fixedly fitted onto the portion of the fixing rod 18 inside the outer sleeve 15, close to the ground. A pair of nail plates 19 are symmetrically fixed to both sides of the connecting ring 16. These nail plates 19 extend outwards and pass through guide grooves 17 formed in the wall of the outer sleeve 15, thus exposing themselves to the outside of the outer sleeve 15. During installation, by striking the exposed nail plates 19 downwards, the entire fixing rod 18 can be driven to move downwards along the trajectory of the guide grooves 17, causing its sharp bottom to insert into the ground 1, achieving initial fixation. In order to keep the bottom part of the fixing rod 18 exposed outside the outer sleeve 15 during the initial installation so that it can be directly inserted into the ground, a limiting member 14 is also provided on the outside of the outer sleeve 15. The limiting member 14 can limit the initial position of the nail plate 19.

[0023] At the top of each row of support devices 7, a support frame 9 is mounted. This support frame 9 has a limiting hole corresponding to the top of the fixing rod 18, allowing the top of the fixing rod 18 to pass through this hole, thus initially positioning the support frame 9. To securely clamp and fix the support frame 9, a retaining plate 20 is also provided at the top of the fixing rod 18. The bottom center of the retaining plate 20 has a downward-extending retaining rod 29, while the top of the fixing rod 18 has a retaining hole that matches the retaining rod 29. Initial alignment and connection are achieved by inserting the retaining rod 29 into the retaining hole. To further strengthen the connection, a connecting plate 30 is fixed around the top outer periphery of the fixing rod 18. A groove is formed at the top of the retaining plate 20, and a set of bolt holes 28 are formed at the bottom of the groove and at corresponding positions on the connecting plate 30 below. By passing bolts through these aligned bolt holes 28 and tightening them, the retaining plate 20 and the fixing rod 18 can be securely connected together. In the actual installation process, the support frame 9 is first placed on top of the fixed rod 18, then the clamping plate 20 is installed and pressed tightly onto the support frame 9, and finally locked with bolts. When the fixing plate 19 is hammered to move the fixed rod 18 downward, it will simultaneously drive the fixed clamping plate 20 downward, thereby pressing the support frame 9 tightly onto the top of the outer sleeve 15, completing the stable installation of the entire support device 7 and the support frame 9.

[0024] The greenhouse film 2 covers the exterior of the overall frame formed by the support frame 9, forming the main enclosed space of the greenhouse. An insulation blanket 3 is installed at the top inside the greenhouse for insulation at night or in low temperatures. The winding device controls the unfolding and winding of the insulation blanket 3, and mainly includes a winding shaft 22, a winding motor 6, and a mounting plate 8. Two winding shafts 22 are provided, located directly below the two long edges of the insulation blanket 3. Both ends of each winding shaft 22 are rotatably connected to a mounting plate 8 via bearings. The winding motor 6 is fixedly mounted on one of the mounting plates 8, and its output shaft is connected to the end of the winding shaft 22, driving the winding shaft 22 to rotate forward and backward, thereby enabling the insulation blanket 3 to be rolled up (to allow light to pass through) or unrolled (to lay out for insulation). To provide stable support for the mounting plate 8 and the entire winding device, a mounting component 4 is installed on the ground 1 corresponding to both ends of each winding shaft 22. Each mounting piece 4 is rotatably connected to a telescopic rod 5 (such as an electric push rod or a gas spring), the top of which is hinged to the mounting plate 8. In this way, when the winding shaft 22 winds up or unwinds the insulation blanket 3, the weight change can be adapted and supported by the extension and retraction of the telescopic rod 5, ensuring the smooth operation of the winding motor 6.

[0025] Specifically, the two rows of support devices 7 located along the short side of the rectangular frame are not at the same height. Taking the two support devices 7 at the middle of the short side as a reference (as the highest point), the height of the support devices 7 gradually decreases towards both sides, so that when viewed from the side, the tops of the multiple support devices 7 form a trapezoidal structure, which is beneficial for drainage and wind resistance of the greenhouse roof. A connecting crossbar 13 is fitted on the top of the fixing rod 18 of the two highest support devices 7 that serve as references. The fixing method of the connecting crossbar 13 is similar to that of the support frame 9, which is also pressed and fixed by a clamping plate 20 or other structure at the top of the fixing rod 18. An opening 11 is provided at the end of the two connecting crossbars 13 that are close to each other. A connecting plate 10 is mounted on the top of the two connecting crossbars 13, and its direction is parallel to the long side of the rectangular frame. A connector 12 is fixed at the center of the top of the connecting plate 10. The connector 12 connects upward to the middle section of the insulation blanket 3, which serves as a central support. A limiting shaft passes through both the opening 11 and the corresponding hole at the bottom of the connector 12, thereby fixing the relative position of the connecting crossbar 13 and the connector 12.

[0026] For the treatment of condensate, this invention includes a dedicated condensate collection device. This device mainly comprises a mounting frame 23, a collection belt 21, and a rubber scraper 26. The mounting frame 23 is located on the side of the mounting plate 8 near the greenhouse film 2, and its length is approximately equal to the height of the greenhouse film 2. A long groove is formed on the mounting plate 8 corresponding to the position of the mounting frame 23, and the mounting frame 23 is inserted into this long groove via a slider 24 for limited sliding. The collection belt 21 is fixed to the bottom of the mounting frame 23 to collect the scraped condensate. A rubber scraper 26 is installed on the top side of the connector 12, with its scraping blade closely adhering to the surface of the insulation blanket 3. When the insulation blanket 3 passes over the rubber scraper 26 during rolling or unrolling, the condensate on its surface is scraped off. The scraped water flows downwards along the mounting frame 23 and is eventually collected by the collection belt 21, preventing it from dripping onto the crops. To prevent the mounting frame 23 from coming off or displacing too much during the sliding process, a first locking block 25 and a second locking block 27 are also provided on the mounting plate 8. They work together to limit the sliding stroke of the slider 24 and ensure that the condensate collection device is always in an effective working position.

[0027] Multiple support devices 7 are placed on the ground 1 in a rectangular layout. The sharp fixing rods 18, which are partially exposed on the outer sleeve 15, are directly inserted into the ground to achieve rapid initial positioning and fixation without the need for complex foundation construction.

[0028] The support frame 9 is fitted onto the top of the fixed rod 18, and then the clamping plate 20 is installed and quickly locked to the connecting plate 30 with bolts. By uniformly hammering the fixing plate 19, the fixed rod 18 is driven to sink and press the clamping plate 20, thus completing the secure installation and height adjustment of the support frame 9 in one go. The process is efficient and the connection is reliable.

[0029] Based on actual needs, the height of the support devices 7 on both sides of the short side of the rectangle can be flexibly adjusted to form a trapezoidal canopy. Subsequently, the connecting crossbars 13, connecting plates 10, and connecting parts 12 can be easily installed to form a stable central support system that can adapt to different drainage and wind resistance requirements.

[0030] The winding device, including a winding shaft 22, a motor 6, a mounting plate 8, and a telescopic rod 5, and the condensate collection device, including a mounting frame 23, a scraper 26, and a collection belt 21, can all be installed as independent modules. Each module is connected to the main structure via simple rotating connections, slider slots, or bolt fixings, making assembly and disassembly easy and maintenance flexible.
