Description

Technical Field

[0001] This utility model relates to the field of grape planting equipment technology, and in particular to a grape trellis support device. Background Technology

[0002] A grape trellis is a specialized structure used to provide support for the growth of climbing plants such as grapes. It is typically constructed using bamboo, wood, or other suitable materials. Its core function is to provide support for the climbing growth of grapevines, ensuring the plant successfully completes its flowering and fruiting cycle. It is a widely used basic agricultural facility in vineyards and plays a vital role in improving the yield and quality of grapes.

[0003] Existing grape trellis technologies suffer from the following drawbacks: Traditionally, grape trellises are constructed using bamboo poles wrapped with wire. While improvements have emerged, such as replacing bamboo poles with stone pillars, the wire-wrapping method remains. Over long-term use, these structures are prone to wire loosening and difficulty in precisely controlling the trellis's posture, leading to malfunctions like tilting and displacement. Furthermore, the overall structure is not easily movable. Some other solutions use steel pipes as the building material; however, the load-bearing capacity of steel pipes is insufficient to meet the load requirements of grapevines bearing fruit, and the poor contact and adhesion between the wires and the smooth outer wall of the steel pipes makes them prone to insecure fixing. Utility Model Content

[0004] The purpose of this utility model is to address the deficiencies in the existing technology by proposing a grape trellis support device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A grape trellis support device includes side steel rods, wire tensioners, and horizontal steel wires; The wire tensioner includes a U-shaped frame, a fixed shaft, a sleeve, and a positioning frame. The fixed shaft is fixedly connected between the two opposite side walls of the U-shaped frame. The sleeve is rotatably connected to the fixed shaft. A positioning ratchet is fixedly connected to the side wall of the sleeve. The positioning frame is rotatably connected to the U-shaped frame to limit the unidirectional rotation of the positioning ratchet. The side steel rod has several mounting holes, and the U-shaped frame is detachably installed in the mounting holes; The end of the horizontal steel wire is fixedly connected to the sleeve.

[0006] Furthermore, the positioning ratchet is provided in two sets, symmetrically arranged on both sides of the sleeve, and the sleeve is provided with fixing holes, and the end of the horizontal steel wire is fixedly connected to the fixing holes.

[0007] Furthermore, the fixing holes are provided in two sets, and the two sets of fixing holes are arranged in parallel; two horizontal steel wires are arranged in parallel on the sleeve.

[0008] Furthermore, the cross-section of the side steel rod is rectangular or U-shaped, and the mounting hole is opened on the side wall of the side steel rod.

[0011] Beneficial effects

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Reference Figures 1-4 A grape trellis support device includes a side steel rod 2, a steel wire tensioner 5, and a horizontal steel wire 4; The wire tensioner 5 includes a U-shaped frame, a fixed shaft, a sleeve 53, and a positioning frame 54. The fixed shaft is fixedly connected between the two opposite side walls of the U-shaped frame. The sleeve 53 is rotatably connected to the fixed shaft. A positioning ratchet 52 is fixedly connected to the side wall of the sleeve 53. The positioning frame 54 is rotatably connected to the U-shaped frame to limit the unidirectional rotation of the positioning ratchet 52. Several mounting holes are provided on the side steel rod 2, and the U-shaped frame is detachably installed in the mounting holes; The end of the horizontal steel wire 4 is fixedly connected to the sleeve 53.

[0022] By setting up a wire tensioner 5 consisting of a U-shaped frame, a fixed shaft, a sleeve 53, and a positioning frame 54, the sleeve 53 can rotate around the fixed shaft, and a positioning ratchet 52 is fixed to the side wall of the sleeve 53. The positioning frame 54 can restrict the unidirectional rotation of the positioning ratchet 52. In actual use, the end of the horizontal steel wire 4 is fixed to the sleeve 53, and the horizontal steel wire 4 is tightened by rotating the sleeve 53. The cooperation between the positioning ratchet 52 and the positioning frame 54 can effectively prevent the sleeve 53 from rotating in the opposite direction, so that the horizontal steel wire 4 is always kept taut, which completely solves the problem of easy loosening and insecure fixation of traditional wire winding methods. At the same time, the side steel pole 2, as the main support, has stronger load-bearing strength and deformation resistance than traditional bamboo poles and stone pillars. It can effectively resist the influence of external forces such as wind and grapevine load, avoid the trellis from tilting or collapsing, and ensure the reliability of support during the growth of grapevines.

[0023] The side steel pole 2 has several mounting holes. The fastening screws 51, which are fixedly connected to the outer wall of the wire tensioner 5, pass through the mounting holes and the wire tensioner is installed on the side steel pole 2 with nuts. This detachable installation method allows the operator to flexibly adjust the installation position of the wire tensioner 5 on the side steel pole 2 according to the actual needs such as the growth height and planting density of the grapevines, thereby adjusting the layout height and spacing of the horizontal steel wires 4 to adapt to the climbing needs of grapevines at different growth stages.

[0024] In other preferred embodiments, two sets of positioning ratchet 52 are provided, symmetrically arranged on both sides of the sleeve 53, and the sleeve 53 is provided with fixing holes, and the end of the horizontal steel wire 4 is fixedly connected to the fixing holes.

[0025] Two sets of positioning ratchet 52 are symmetrically arranged on both sides of the sleeve 53, and cooperate with the positioning frame 54 to form a two-way limiting structure. Compared with the single-sided ratchet design, it can more evenly bear the torque generated when the horizontal steel wire 4 is tightened, effectively avoid the sleeve 53 being shifted on one side, and ensure the meshing stability of the positioning ratchet 52 and the positioning frame 54.

[0026] Specifically, two sets of fixing holes are provided, and the two sets of fixing holes are arranged in parallel; two horizontal steel wires 4 are arranged in parallel on the sleeve 53. The two horizontal steel wires effectively distribute the load pressure generated by the climbing of grapevines and fruit hanging, avoiding the tensile deformation or breakage of steel wires caused by local stress concentration. The structure with the double steel wires arranged in parallel forms a stable support plane, which can more evenly support the grapevine branches and fruits, reduce the problem of tilting and swaying of the frame due to excessive force on one side, and significantly improve the overall load-bearing capacity and wind resistance of the support device.

[0027] In other preferred embodiments, the side steel rod 2 has a rectangular or U-shaped cross-section, and the mounting holes are formed on the side wall of the side steel rod.

[0028] In other preferred embodiments, at least one intermediate steel rod 3 is further included. The intermediate steel rod 3 has a positioning groove corresponding to the mounting hole. The positioning groove includes a positioning section and a wire feeding section. The area of ​​the positioning section is larger than the area of ​​the wire feeding section, and the height of the lower end of the positioning section is lower than the height of the lower end of the wire feeding section.

[0029] The addition of the central steel rod 3 effectively fills the support gap between the side steel rods 2, forming a multi-point collaborative support frame structure with the side steel rods 2, significantly enhancing the overall deformation resistance and rigidity of the grape trellis. Simultaneously, the positioning groove limits the movement of the horizontal steel wire 4, preventing it from shifting laterally under stress or wind, ensuring that the horizontal steel wire 4 always maintains its preset parallel position, further improving the stable support for the grapevine branches, leaves, and fruit, and effectively resisting the impact of severe weather on the trellis.

[0030] The positioning groove adopts a stepped structure design of positioning section and wire feeding section, and the area of ​​positioning section is larger than that of wire feeding section, while the lower end of positioning section is lower than the lower end of wire feeding section, forming a convenient insertion and locking installation path.

[0031] In other preferred embodiments, a side tension wire 1 is also provided in the mounting hole of the side steel rod 2. One end of the side tension wire 1 is fixedly connected to the mounting hole, and the other end is fixedly connected to the anchor. This structure can effectively transfer the lateral tensile force and vertical load borne by the side steel rod 2 to the ground foundation, greatly enhancing the stability of the side steel rod 2.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
