Description

Technical Field

[0001] This utility model relates to the field of bird netting technology, and in particular to an easily extendable bird netting for agricultural planting. Background Technology

[0002] Bird netting is a mesh fabric made primarily of polyethylene (PE) and heddles. It features UV resistance, corrosion resistance, and high tensile strength. It is widely used in agricultural settings such as orchards and vegetable growing areas to prevent birds from pecking at crops and fruits (such as grapes, cherries, and pears), reducing direct economic losses, lowering the risk of birds spreading pests and diseases, protecting crop health, and providing additional insect control and shade. Some netting can even withstand extreme weather such as hail. The mesh size (3-4.5 cm) and color (yellow, blue, etc.) need to be selected based on the size of the birds and the environment. Three-dimensional installation can enhance the protective effect.

[0003] In current practical applications, bird nets are used to enclose the perimeter and top of plants to provide protection. However, after use, bird nets are not easy to store and tend to get tangled, affecting their usability. Therefore, a more flexible bird net for agricultural planting is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an easily extendable bird-proof net for agricultural planting, solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easily extendable bird-proof net for agricultural planting, comprising at least two fixed frames and a bird-proof net body disposed between the two fixed frames. Each fixed frame has a winding roller inside, and both ends of the bird-proof net body are fixedly connected to and wound around the winding roller. Each winding roller is symmetrically equipped with a shielding plate, and a transmission rod is installed at the bottom of one shielding plate. A first bevel gear is installed on the transmission rod. Each fixed frame is rotatably connected to a rotating rod near the bottom, and one end of the rotating rod extends into the interior of the fixed frame and is equipped with a second bevel gear.

[0006] As a further technical solution of this utility model, the second bevel gear meshes with the first bevel gear, and a crank handle is installed at the other end of the rotating rod outside the fixed frame.

[0007] As a further technical solution of this utility model, the bird net body is wound on the winding roller between two shielding discs, and a fixing rod is installed at the bottom of each fixing frame, and the bottom of each fixing rod is conical.

[0008] As a further technical solution of this utility model, a connecting post is provided through the top of each fixed frame and is rotatably connected thereto. The bottom of the connecting post extends into the interior of the fixed frame and is fixedly connected to the top of another shielding plate.

[0009] As a further technical solution of this utility model, a right-angle plate is installed at the top of each fixed frame, the top of the connecting column passes through the top of the right-angle plate and is rotatably connected to it, and a limiting rod is slidably connected to one side of the right-angle plate.

[0010] As a further technical solution of this utility model, a first baffle is installed near one end of the limiting rod, a second baffle is installed near the other end of the limiting rod, a spring is sleeved on the limiting rod, and a limiting hole adapted to the limiting rod is provided through the connecting column.

[0011] This utility model provides an easily extendable bird net for agricultural planting, which has the following advantages compared with the prior art:

[0012] This design provides an easily extendable bird-proof net for agricultural planting. Through a transmission rod, first and second bevel gears, and a winding roller, rotating the rod drives the second bevel gear, which in turn drives the transmission rod. This rotation of the transmission rod, in turn, causes the winding roller to rotate, allowing the bird-proof net to be wound onto the roller and stored within a fixed frame. The design is convenient to use. When the bird-proof net is needed to enclose the planting area, it can be pulled out from within the fixed frame. This design allows the bird-proof net to be stored within a fixed frame and pulled out to enclose the agricultural planting area when needed. Attached Figure Description

[0018] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution for an easily extendable bird net for agricultural planting, including at least two fixed frames 1 and a bird net body 2 set between the two fixed frames 1. Each fixed frame 1 has a fixed rod 3 installed at its bottom. The bottom of each fixed rod 3 is conical. The fixed rod 3 is inserted into the ground, and a fixed frame 1 is installed outside the agricultural planting area.

[0020] Each fixed frame 1 is equipped with a winding roller 11 inside. Both ends of the bird net body 2 are fixedly connected to and wound around the winding roller 11. Each winding roller 11 is symmetrically equipped with a shielding plate 10. A transmission rod 12 is installed at the bottom of one shielding plate 10. A first bevel gear 13 is installed on the transmission rod 12. A rotating rod 14 is rotatably connected near the bottom of each fixed frame 1. One end of the rotating rod 14 extends into the interior of the fixed frame 1 and is equipped with a second bevel gear 15. The second bevel gear 15 meshes with the first bevel gear 13. The other end of the rotating rod 14 is located outside the fixed frame 1 and is equipped with a crank 16. The bird net body 2 is wound on the take-up roller 11 between two shielding discs 10. Rotating the rotating rod 14 drives the second bevel gear 15 to rotate. The second bevel gear 15 meshes with the first bevel gear 13, driving the transmission rod 12 to rotate. When the transmission rod 12 rotates, it drives the take-up roller 11 to rotate. The bird net body 2 pulled out from the fixed frame 1 can be wound on the take-up roller 11 and stored in the fixed frame 1. When the bird net body 2 is needed, it can be pulled out from inside the fixed frame 1, so that the bird net body 2 is taut between the two fixed frames 1 and used to fence off the agricultural planting area.

[0021] Each fixed frame 1 has a connecting post 4 rotatably connected to its top end. The bottom of the connecting post 4 extends into the interior of the fixed frame 1 and is fixedly connected to the top end of another shielding plate 10. Each fixed frame 1 has a right-angle plate 5 installed at its top end. The top end of the connecting post 4 passes through the top end of the right-angle plate 5 and is rotatably connected to it. A limiting rod 6 slidably connects to one side of the right-angle plate 5. A first baffle 7 is installed near one end of the limiting rod 6, and a [missing information - likely a baffle plate] is installed near the other end of the limiting rod 6. The second baffle 8 has a spring 9 fitted on the limiting rod 6, and the connecting column 4 has a limiting hole that matches the limiting rod 6. When the limiting rod 6 is pulled, it slides on the right-angle plate 5. The second baffle 8 squeezes the spring 9, and the limiting rod 6 retracts into the limiting hole on the connecting column 4, allowing the winding roller 11 to rotate. When the limiting rod 6 is inserted into the limiting hole on the connecting column 4, the connecting column 4 is limited, and the winding roller 11 is also limited. This is used when the bird net body 2 is stored inside the fixed frame 1.

[0022] The working principle of this utility model is as follows: the fixed rod 3 is inserted into the ground, and a fixed frame 1 is installed outside the agricultural planting area. The limiting rod 6 is pulled, and the limiting rod 6 slides on the right-angle plate 5. The second baffle 8 squeezes the spring 9, and the limiting rod 6 exits into the limiting hole on the connecting column 4. The rotating rod 14 is rotated, and the rotating rod 14 drives the second bevel gear 15 to rotate. The second bevel gear 15 meshes with the first bevel gear 13 to drive the transmission rod 12 to rotate. When the transmission rod 12 rotates, it drives the winding roller 11 to rotate, pulling the bird net body 2 out inside the fixed frame 1, so that the bird net body 2 is taut between the two fixed frames 1 to achieve enclosure. When not in use, when the limiting rod 6 is inserted into the limiting hole on the connecting column 4, the connecting column 4 is limited, and the winding roller 11 is limited at the same time, so that the bird net body 2 can be rolled up and stored inside the fixed frame 1.

[0023] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
