Description

Technical Field

[0001] This utility model relates to the field of plant climbing frame technology, specifically a simplified net frame that facilitates the climbing of yam vines. Background Technology

[0002] Yam is the dried rhizome of a plant belonging to the genus Dioscorea in the family Dioscoreaceae. It is a valuable food and medicine. Yam is a perennial climbing herb, and its vines need to be trellised and netted during cultivation.

[0003] Traditional yam planting trellises typically consist of wooden or iron rods bound together in a triangular structure, with the netting then attached to the triangular frame. This method, which uses the rods inserted into the soil for fixation, offers poor stability and wind resistance. Therefore, wind-resistant planting trellises have emerged on the market. For example, utility model patent CN206923370U discloses a trellis for preventing purple yam vines from being blown over by the wind. This trellis includes a frame and several climbing nets. The frame consists of a fixed cement base frame and several uprights fixed to the base frame. The base frame is buried in the soil. The uprights are arranged in two rows, connected by horizontal bars. Each horizontal bar corresponds to two climbing nets, with the upper and lower ends of the climbing nets fixed to the horizontal bar and the ground, respectively. While this type of growing frame offers better stability and wind resistance, its fixed base frame is made of cement, making it heavy and immovable. Its complex structure can also obstruct yam harvesting. Furthermore, the netting angle adjustment mechanism is cumbersome, requiring the use of a crank to adjust the height of the crossbar to change the netting angle. During routine maintenance, the crank is easily accidentally activated, causing the crossbar to shift and potentially pulling on the yam vines, resulting in damage. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned technical problems and provide a lightweight and simplified net frame that facilitates the climbing of yam vines.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a simplified net frame for easy climbing of yam vines, comprising a support frame and a hanging net. The support frame includes a base frame and multiple side frames installed on the base frame. The base frame has an inverted T-shaped cross-section, with its horizontal part buried in the soil and an opening groove on the top surface of its vertical part. Each side frame includes two side rods hinged together at their ends. The side rods are hollow tubular structures, and a limiting post is movably provided at one end of each side rod that is far apart from the other. Multiple limiting holes are provided on the side wall of the opening groove, and the multiple limiting holes are arranged along the length of the opening groove. The limiting post cooperates with the limiting holes to fix the side frame. A telescopic reinforcing rod is provided between the two side rods, and the telescopic reinforcing rod and the two side rods form a stable triangular structure. The two ends of the telescopic reinforcing rod are movably connected to the side rods. Multiple hooks are provided at both ends of the hanging net, and multiple hanging rings are provided on the left and right sides of the side rods. The hanging net is installed on the side rods of two adjacent supports through the hooks and hanging rings.

[0006] Furthermore, the limiting post includes a fixed part and a telescopic part. The fixed part is installed inside the side rod, and its end face is flush with the side wall of the side rod. The fixed part has telescopic grooves at both ends and a spring inside. The telescopic part is located inside the telescopic groove, and the two ends of the spring are respectively connected to the telescopic groove and the end of the telescopic part.

[0007] Furthermore, a notch is provided above the limiting hole, and the width of the notch is smaller than the diameter of the limiting hole.

[0008] Furthermore, the fixing part is rotatably connected to the side rod, and the end of the telescopic part away from the telescopic groove is provided with a limiting piece. The limiting piece and the limiting post form a U-shaped structure. The thickness of the limiting piece corresponds to the notch, so that the limiting piece can pass through the notch.

[0009] Furthermore, the telescopic reinforcing rod includes a grooved rod and a sliding rod that cooperate with each other. The grooved rod has a strip-shaped through hole on its side wall, and the sliding rod has a threaded post at one end near the grooved rod. The threaded post passes through the strip-shaped through hole and is fitted with a fastening nut on its outer side.

[0010] Furthermore, the cross-section of the sliding rod is C-shaped, and the cross-section of the sliding rod is a horizontally inverted T-shaped structure, with the two fitting together tightly.

[0011] The beneficial effects of this utility model are as follows: This product adopts an innovative design and has a simple structure. The base frame uses a unique inverted T-shaped structure, burying the horizontal part in the soil, significantly increasing the contact area with the soil, thus achieving a more stable fixing effect; the side frame consists of two side rods hinged together, making it easier to adjust the angle between them. The side rods are securely fixed through the cooperation of the limiting posts and limiting holes. Furthermore, the connection between the hanging net and the side rods uses a simple hook and ring combination, making the installation process simple and efficient.

[0012] The side poles feature a hollow tubular structure, making them lightweight and durable. Telescopic reinforcing bars are installed between the two side poles, significantly enhancing the stability of the support while maintaining its lightweight nature. The base frame, buried in the ground, is more robust than traditional simple grid structures, improving wind resistance. Attached Figure Description
