Description

Technical Field

[0001] This utility model relates to the field of cowpea cultivation technology, and in particular to a greenhouse suitable for cowpea cultivation. Background Technology

[0002] Cowpeas, also known as string beans, are annual climbing herbaceous vines or nearly erect herbaceous plants belonging to the genus *Vigna* in the legume family. They are rich in protein, dietary fiber, vitamins, and minerals, and have gained widespread popularity due to their excellent nutritional value and diverse culinary uses.

[0003] Cowpeas can be cultivated in a variety of ways, including traditional open-field planting to make full use of natural sunlight and soil conditions, or greenhouse cultivation. Greenhouse cultivation not only effectively protects against harsh weather but also significantly improves the yield and quality of cowpeas through precise temperature and humidity control, while extending their supply period to meet the continuous market demand for fresh cowpeas.

[0004] Erecting A-frame trellises manually requires a lot of time and physical effort, resulting in high labor intensity, especially in large-scale planting where efficiency is low. Furthermore, subsequent dismantling and recycling increase the labor burden. Additionally, the angle and stability of manually erected trellises are difficult to guarantee, making them prone to tipping over due to insecure construction. Utility Model Content

[0006] Specifically, the technical problem to be solved by this utility model is to provide a greenhouse suitable for cowpea cultivation, so as to solve the technical problems of the current manual construction of "A" frame which is time-consuming, labor-intensive, inefficient, especially when planting on a large scale, and troublesome to dismantle and recycle, and the inconsistent angles, poor stability, and easy to tip over.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] A greenhouse suitable for cowpea cultivation includes a greenhouse frame covered with a protective tarpaulin, and a main body of bean-supporting frames arranged in a row within the greenhouse frame.

[0009] The greenhouse frame includes vertically distributed main columns, and a top beam located below the protective canopy is provided between the main columns. The top beam has linearly arranged slots, and fastening seats are fixedly installed at both ends of the top beam. The top beam is fixedly installed between the main columns by the fastening seats.

[0010] The main body of the bean-building frame includes a base located below the top beam. An assembly seat is fixedly installed on the top of the base. A U-shaped locking block adapted to the assembly seat is slidably connected to the base. The base is detached and installed on the top beam through the assembly seat. An assembly through hole is opened in the base. An assembly bolt for fixing the U-shaped locking block is also provided in the base. One end of the assembly bolt passes through the assembly through hole and extends into the U-shaped locking block, which is located in the top beam. Both ends of the base are hinged to main climbing rods.

[0011] As an improved technical solution, the U-shaped blocks are arranged linearly along the axial direction of the top beam, and the U-shaped blocks correspond to the slots.

[0012] As an improved technical solution, a limiting groove is provided on the inner side of the main climbing rod, and an auxiliary climbing rod is slidably connected to each of the main climbing rods. A ground socket is hinged to one end of the auxiliary climbing rod extending outside the main climbing rod, and a limiting block adapted to the limiting groove is fixedly installed at one end of the auxiliary climbing rod located in the main climbing rod.

[0013] As an improved technical solution, the greenhouse frame also includes a guide beam fixedly installed on the main column by fastening seats. At the end of the guide beam away from the main column, there are secondary columns that are distributed parallel to the main column. Side wall frames for supporting the protective shed fabric are also fixedly installed between the secondary columns.

[0014] As an improved technical solution, a secondary beam for supporting the protective canopy is fixedly installed at one end of the main column that passes through the fastening seat. The secondary beam is located above the top beam and is distributed parallel to the top beam.

[0015] As an improved technical solution, the main column has linearly arranged adjustment holes, and an adjustment seat is slidably connected to the main column. The adjustment seat is provided with an adjustment knob for fixing the adjustment seat and matching the adjustment holes. A sprinkler water tank is also fixedly installed on the adjustment seat. The sprinkler water tanks are connected to each other through a sprinkler pipe, and the sprinkler pipe is located below the top beam.

[0016] As an improved technical solution, each guide beam is slidably connected to a guide slider, and the guide sliders are symmetrically distributed on both sides of the adjustment hole. A connecting rod is provided between the guide slider and the adjustment seat. The top end of the connecting rod is hinged to the corresponding guide slider, and the bottom end of the connecting rod is hinged to the adjustment seat.

[0017] After adopting the above technical solution, the beneficial effects of this utility model are:

[0018] 1. This utility model uses a snap-fit ​​method of mounting base and U-shaped clip to hoist the base onto the top beam, and uses mounting bolts to firmly connect the base and the top beam through the mounting through hole, which realizes the rapid hoisting of the main body of the bean frame onto the top beam, thereby effectively shortening the construction time.

[0019] 2. In this utility model, when the main climbing pole is extended, the secondary climbing pole can be extended and retracted according to the growth needs of the cowpea vines. The limiting block slides in the limiting groove inside the main climbing pole to prevent slippage, and the other end of the secondary climbing pole is fixed to the ground by the ground socket, thus realizing the stable climbing of the cowpea vines without the need for subsequent dismantling and recycling.

[0020] 3. This utility model, by adjusting the screw and cooperating with the adjustment hole on the main column to fix the position of the adjustment seat on the main column, allows the height of the sprinkler water tank to be adjusted by the adjustment seat. Then, with the help of the connecting rod on the guide slider that can slide along the guide beam, the adjustment seat is provided with tension to complete the height fixation, so that the sprinkler water tank can provide a uniform and stable irrigation water source for cowpea plants.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0032] like Figures 1 to 7 As shown in the figure, this embodiment provides a greenhouse suitable for cowpea cultivation. This greenhouse includes a greenhouse frame covered with a protective fabric 2. The greenhouse frame contains a series of bean-supporting frame bodies. The greenhouse frame includes vertically distributed main columns 1. A top beam 3 is located between the main columns 1, below the protective fabric 2. The top beam 3 has linearly arranged slots 302. Fastening seats 301 are fixedly installed at both ends of the top beam 3. The top beam 3 is fixedly installed between the main columns 1 via the fastening seats 301. The bean-supporting frame body includes a base 4 located below the top beam 3. An assembly seat 401 is fixedly installed on the top of the base 4. A U-shaped locking block 5, adapted to the assembly seat 401, is slidably connected to the base 4. The base 4 is detachably installed onto the top beam 3 via the assembly seat 401. The base 4 has an assembly through hole 402 and also provides a mounting hole for fixing the U-shaped locking block 5. The mounting bolt 6 passes through the mounting through hole 402 and extends into the U-shaped clip 5, with one end located in the top beam 3. Both ends of the base 4 are hinged to the main climbing rod 7. The protective shed cloth 2 is used to block the harsh weather and protect the cowpea growing environment. The main body of the bean frame is used to support the cowpea plants and is in a folded state when not in use. The main column 1 serves as the main support structure of the greenhouse. The top beam 3 is used to connect the main column 1 and hoist the main body of the bean frame. The fastening seat 301 is used to fix the main column 1 and the top beam 3. The U-shaped clip 5 is sleeved on the top beam 3 and can move along its axial direction. The base 4 is engaged with the U-shaped clip 5 on the top beam 3 through the mounting seat 401. The mounting bolt 6 can pass through the mounting through hole 402 to fix the mounting seat 401 and the U-shaped clip 5 connected to the base 4 to the top beam 3. The main climbing rod 7 on the base 4 can guide the cowpea vines to grow upward in the unfolded state.

[0033] The U-shaped locking blocks 5 are arranged linearly along the axial direction of the top beam 3, and the U-shaped locking blocks 5 correspond to the locking slots 302. The U-shaped locking blocks 5 can slide along the axial direction of the top beam 3 and never disengage from the top beam 3. When they correspond to the locking slots 302, they complete the locking with the top beam 3.

[0034] A limiting groove 701 is provided on the inner side of the main climbing pole 7. A secondary climbing pole 8 is slidably connected to each main climbing pole 7. One end of the secondary climbing pole 8 extending outside the main climbing pole 7 is hinged to a ground socket 801. A limiting block 802, adapted to the limiting groove 701, is fixedly installed at one end of the secondary climbing pole 8 within the main climbing pole 7. The secondary climbing pole 8 can protrude from the main climbing pole 7, thus facilitating the climbing of the cowpea vine. The ground socket 801 is used to assist in fixing the bottom of the secondary climbing pole 8, and the limiting block 802 prevents the secondary climbing pole 8 from sliding out of the main climbing pole 7.

[0035] The greenhouse frame also includes a guide beam 9 fixedly installed on the main column 1 by a fastening seat 301. At the end of the guide beam 9 away from the main column 1, there are auxiliary columns 10 distributed parallel to the main column 1. Side wall frames 11 for supporting the protective shed fabric 2 are also fixedly installed between the auxiliary columns 10. The side wall frames 11 can form a frame structure by cooperating with the auxiliary columns 10 and the main column 1, thereby increasing the lateral wind resistance of the protective shed fabric 2.

[0036] The main column 1 has a secondary beam 12 fixedly installed at one end through the fastening seat 301 to support the protective shed 2. The secondary beam 12 is located above the top beam 3 and is distributed parallel to the top beam 3. The secondary beam 12 can further enhance the support effect of the protective shed 2 and prevent the main body of the bean frame from accidentally touching the protective shed 2 when it is unfolded or retracted.

[0037] The main column 1 has linearly arranged adjustment holes 101. An adjustment seat 13 is slidably connected to the main column 1. The adjustment seat 13 is provided with an adjustment knob 14 for fixing the adjustment seat 13 and matching the adjustment hole 101. A sprinkler water tank 15 is also fixedly installed on the adjustment seat 13. The sprinkler water tanks 15 are connected to each other through a sprinkler pipe 16, and the sprinkler pipe 16 is located below the top beam 3. The adjustment seat 13 can adjust the height of the sprinkler water tank 15 by adjusting the knob 14 in the corresponding adjustment hole 101, and provide irrigation for the cowpea plants through the sprinkler pipe 16.

[0038] Guide sliders 17 are slidably connected to the guide beam 9, and the guide sliders 17 are symmetrically distributed on both sides of the adjustment hole 101. A connecting rod 18 is provided between the guide slider 17 and the adjustment seat 13. The top end of the connecting rod 18 is hinged to the corresponding guide slider 17, and the bottom end of the connecting rod 18 is hinged to the adjustment seat 13. The guide slider 17 can slide along the guide beam 9 and provide tension to the adjustment seat 13 through the connecting rod 18, thereby assisting the adjustment screw 14 to fix the height of the adjustment seat 13.

[0039] When constructing a greenhouse for cowpea cultivation, first install the main support column 1 vertically on the ground to ensure its stability. Then, fix the top beam 3 between the main support columns 1 using fastening base 301. Cover the top beam 3 with protective tarpaulin 2 and place the base 4 under the top beam 3. Hoist the base 4 onto the top beam 3 by engaging the mounting base 401 with the U-shaped clip 5. Securely connect the base 4 to the top beam 3 by passing the mounting bolts 6 through the mounting through hole 402. When in use, unfold the main climbing pole 7 to guide the cowpea vines to grow upwards.

[0040] When the main climbing pole 7 is extended, the secondary climbing pole 8 can be extended and retracted according to the growth needs of the cowpea vines. Its limiting block 802 slides in the limiting groove 701 inside the main climbing pole 7 to prevent the secondary climbing pole 8 from sliding out. The other end of the secondary climbing pole 8 is fixed to the ground through the ground socket 801, which further enhances the support effect and ensures that the cowpea vines can climb stably, so that there is no need to dismantle and recycle it.

[0041] By adjusting the screw 14 in conjunction with the adjustment hole 101 on the main column 1, the position of the adjustment seat 13 on the main column 1 is fixed, so that the water tank 15 connected through the sprinkler pipe 16 can be adjusted in height through the adjustment seat 13, ensuring that the water tank 15 can provide a uniform and stable irrigation water source for the cowpea plants. The connecting rod 18 on the guide slider 17 that can slide along the guide beam 9 provides tension to the adjustment seat 13, assisting the adjustment screw 14 in fixing the height of the adjustment seat 13.

[0042] During use, the guide beam 9 and the side wall frame 11 enhance the greenhouse's lateral wind resistance, and the secondary beam 12 further enhances the support effect, ensuring that it completely covers the entire greenhouse frame and plays a role in blocking severe weather.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
