Description

Technical Field

[0001] This utility model belongs to the field of agricultural planting technology, specifically relating to an improved greenhouse frame for climbing vegetable crops. Background Technology

[0002] Vegetable cultivation requires farmers to utilize vertical greenhouse structures to improve greenhouse cultivation effects, ensure the growth and quality of vegetables in large-scale farmland, mitigate climatic and ecological disturbances in farmland, and enhance the universality and efficiency of greenhouse agriculture.

[0003] In vegetable greenhouses, to aid the vertical growth of climbing vegetables, facilitate later management and harvesting, and ensure ventilation and lighting conditions between crops, trellis ropes are used to provide climbing and support for these crops (such as cucumbers, tomatoes, and lychees). Currently, the trellis ropes are installed by fixing multiple trellis wires between adjacent horizontal bars in the greenhouse frame, each positioned above and parallel to the corresponding row of climbing vegetables. Several trellis ropes, with their lower ends fixed to the ground, are then vertically attached to these wires to support each vine. However, due to the large span and length of greenhouses, and the large number and weight of crops suspended from the frame, this increases the load on the greenhouse structure. Excessive weight or improper fixing can easily cause deformation or damage to the frame at both ends, severely affecting the greenhouse's strength and stability. Therefore, it is necessary to improve the current greenhouse structure to address these issues. Utility Model Content

[0004] The technical problem solved by this utility model is to provide an improved greenhouse frame for climbing vegetable crops. Based on the structural characteristics of existing greenhouse frames, multiple parallel reinforcing rods are provided between the horizontal tie rods at the ends of the longitudinal beams and their adjacent horizontal tie rods. The ends of the reinforcing rods perpendicular to the horizontal tie rods are detachably and fixedly connected to the corresponding ends of the horizontal tie rods through quick-connect fittings. This improves the structural strength at both ends of the greenhouse frame and solves the problem of deformation or damage at both ends of the greenhouse frame due to excessive weight of the vines when planting climbing vegetable crops. It also improves the end strength of the greenhouse frame in use and ensures the stability and safety of the greenhouse frame during use.

[0005] The technical solution adopted in this utility model is as follows: an improved greenhouse frame for climbing vegetable crops, including two parallel longitudinal beams, several arched rods with both ends fixedly connected to the two longitudinal beams and evenly distributed parallel to the length of the longitudinal beams, several longitudinal tie rods parallel to the longitudinal beams and fixedly connected to the several arched rods, several uprights with their upper ends fixedly connected to the longitudinal beams and their lower ends pre-embedded and fixed in the soil, and several horizontal tie rods distributed along the length of the longitudinal beams. The longitudinal rods are located below the several arched rods and fixedly connected to the several horizontal tie rods. Several central support columns are provided between the two longitudinal beams and distributed along their length. The upper end of the central support column is fixedly connected to the middle of the corresponding arched rod, and the lower end of the central support column is pre-embedded and fixed in the soil. When there is a horizontal tie rod at the location of the central support column, it is fixedly connected to the horizontal tie rod. Several parallel reinforcing rods are provided between the horizontal tie rods at the ends of the longitudinal beams and their adjacent horizontal tie rods. The reinforcing rods are perpendicular to the horizontal tie rods, and the ends of the reinforcing rods are detachably fixedly connected to the corresponding horizontal tie rods through quick connectors.

[0006] Among them, the cross braces at other positions on the longitudinal beam are staggered with reinforcing bars as needed.

[0007] Furthermore, the quick connector includes an L-shaped connecting block and a clamping block. The horizontal side of the L-shaped connecting block faces upward and the vertical side faces the reinforcing rod. The upper end face of the clamping block and the bottom surface of the notch formed by the horizontal and vertical plates of the L-shaped connecting block are both provided with grooves that are adapted to the horizontal tie rod. The horizontal tie rod is adapted to the clamping hole formed by the two grooves after the clamping block and the L-shaped connecting block are fastened together. The L-shaped connecting block and the clamping block are clamped and fixed by two bolts that fix the L-shaped connecting block and the clamping block together. The end face of the L-shaped connecting block facing the reinforcing rod is provided with a connecting hole, and the end of the reinforcing rod is inserted into the connecting hole. The L-shaped connecting block and the reinforcing rod are detachably fixed together by bolts that pass through the through holes on the L-shaped connecting block and the reinforcing rod.

[0008] Advantages of this utility model compared to the prior art:

[0009] 1. Based on the structural characteristics of existing greenhouse frames, this technical solution incorporates multiple parallel reinforcing bars between the horizontal tie rods at the ends of the longitudinal beams and their adjacent horizontal tie rods. The ends of these reinforcing bars, perpendicular to the horizontal tie rods, are detachably and securely connected to their corresponding ends via quick-connect fittings. This improves the structural strength at both ends of the greenhouse frame and solves the problem of deformation or damage at the ends of the frame due to excessive weight of the vines when planting climbing vegetables.

[0010] 2. This technical solution uses a quick connector including an L-shaped connecting block and a clamping block. When installing the reinforcing rod, simply fix the L-shaped connecting blocks at both ends of the reinforcing rod, then place the reinforcing rod on the two adjacent horizontal tie rods through the L-shaped connecting blocks, and fix the clamping block to the L-shaped connecting block. The connection structure is reasonably designed, the operation process is simple, and the overall strength is good after connection.

[0011] 3. This technical solution has a simple structure, flexible installation location, low cost, and improves the end strength of the shed frame when put into use, ensuring the stability and safety of the shed frame during use, and has high use value. Attached Figure Description

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0017] Improved greenhouse frame for climbing vegetable crops, such as Figure 1-2 As shown, the structure includes two parallel longitudinal beams 1, several arched rods 2 whose two ends are fixedly connected to the two longitudinal beams 1 and are evenly distributed parallel to the length of the longitudinal beams 1, several longitudinal tie rods 3 that are parallel to the longitudinal beams 1 and fixedly connected to the several arched rods 2, several columns 4 whose upper ends are fixedly connected to the longitudinal beams 1 and whose lower ends are pre-embedded and fixed in the soil, and several transverse tie rods 5 distributed along the length of the longitudinal beams 1. Longitudinal rods 8 are located below the several arched rods 2 and fixedly connected to the multiple transverse tie rods 5. Between the two longitudinal beams 1... Multiple central support columns 6 are provided along the length direction. The upper end of each central support column 6 is fixedly connected to the middle of the corresponding arched rod 2, while the lower end of the central support column 6 is pre-embedded and fixed in the soil. When there is a horizontal tie rod 5 at the location of the central support column 6, it is fixedly connected to the horizontal tie rod 5. Multiple parallel reinforcing rods 7 are provided between the horizontal tie rod 5 at the end of the longitudinal beam 1 and its adjacent horizontal tie rod 5. The reinforcing rods 7 are arranged perpendicular to the horizontal tie rods 5, and the ends of the reinforcing rods 7 are detachably fixedly connected to the corresponding horizontal tie rods 5 through quick-connect fittings. Figure 1 (Only one point is shown in the diagram). In the above structure, based on the structural characteristics of the existing shed frame, multiple parallel reinforcing rods 7 are provided between the horizontal tie rod 5 at the end of the longitudinal beam 1 and its adjacent horizontal tie rod 5. The ends of the reinforcing rods 7, which are perpendicular to the horizontal tie rods 5, are detachably and fixedly connected to the corresponding ends of the horizontal tie rods 5 through quick connectors. This improves the frame strength at both ends of the shed frame and solves the problem of deformation or damage at both ends of the shed frame due to excessive weight of the hanging vines when planting climbing vegetable crops.

[0018] Among them, the horizontal tie rods 5 at other positions on the longitudinal beam 1 are staggered with the reinforcing rods 7 as needed, so as to meet the strength requirements of the positions with larger loads at different positions. The installation is flexible and convenient, and can be adjusted according to different crops.

[0019] like Figure 2As shown, the specific structure of the quick connector is as follows: The quick connector includes an L-shaped connecting block 9 and a clamping block 10. The horizontal side of the L-shaped connecting block 9 faces upward and the vertical side faces the reinforcing rod 7. The upper end face of the clamping block 10 and the bottom surface of the notch formed by the horizontal and vertical plates of the L-shaped connecting block 9 are both provided with grooves 11 that are adapted to the horizontal tie rod 5. The horizontal tie rod 5 is adapted to fit into the clamping hole formed by the two grooves 11 after the clamping block 10 and the L-shaped connecting block 9 are fastened together. The horizontal tie rod 5 is clamped and fixed by the L-shaped connecting block 9 and the clamping block 10 through two bolts that fix the L-shaped connecting block 9 and the clamping block 10. The end face of the L-shaped connecting block 9 facing the reinforcing rod 7 is provided with a connecting hole 12, and the end of the reinforcing rod 7 is inserted into the connecting hole 12 and connected through the L-shaped connecting block 10. Bolts through the through holes on block 9 and reinforcing rod 7 detachably connect L-shaped connecting block 9 to reinforcing rod 7. In the above structure, a quick connector including L-shaped connecting block 9 and clamping block 10 is used. When installing reinforcing rod 7, it is only necessary to fix L-shaped connecting blocks 9 at both ends of reinforcing rod 7, then place reinforcing rod 7 on two adjacent horizontal tie rods 5 through L-shaped connecting blocks 9, and fix clamping block 10 to L-shaped connecting blocks. The connection structure is reasonably designed, the operation process is simple, and the overall strength is good after connection. In order to facilitate hole alignment, one of the through holes on reinforcing rod 7 and L-shaped connecting block 9 can be processed into an oblong hole. In this way, after L-shaped connecting block 9 and clamping block 10 are fixedly connected to clamp the horizontal tie rod 5, it is only necessary to tighten the bolts connected to reinforcing rod 7 and L-shaped connecting block 9.

[0020] This technical solution addresses the shortcomings of existing greenhouses in use by designing a structure to enhance the strength of the greenhouse frame, thereby improving the strength of the frame and ensuring its strength and stability during use. The structure is simple, flexible in installation location, and low in cost. It improves the end strength of the greenhouse frame, ensuring its stability and reliability during use, and has high practical value.
