Description

Technical Field

[0001] This utility model relates to the field of rice breeding equipment technology, specifically a rice breeding isolation cover for rice breeding racks. Background Technology

[0002] In the field of rice breeding, the role of breeding isolation covers is crucial in creating a pure, stable, and suitable environment for rice growth. They not only effectively block external interference factors such as pollen and pests, but also regulate internal conditions such as temperature, humidity, and light to a certain extent, thereby ensuring the purity and quality of rice breeding and improving the breeding success rate.

[0003] However, the rice breeding isolation covers commonly available on the market have revealed many shortcomings in practical applications. From a structural design perspective, traditional isolation covers are mostly integrated, fixed structures. During installation, they require significant manpower and time for assembly, and their position and shape are essentially fixed after installation, making it difficult to flexibly adjust them according to the actual spatial layout of the breeding site and the needs of different rice growth stages. For example, in the early stages of rice growth, the plants are shorter and require less space, but existing isolation covers cannot easily reduce the internal space, resulting in wasted space. Conversely, as the rice grows taller and denser in the later stages, existing isolation covers may not provide sufficient vertical and horizontal space, restricting normal rice growth. Utility Model Content

[0004] To address the shortcomings mentioned in the background art, the purpose of this utility model is to provide a rice breeding isolation cover for rice breeding racks. A rotary motor drives a screw to rotate. Since the screw is threadedly connected to a movable seat, it can move the movable seat up and down, thereby moving the connecting ring and support frame connected to it. This allows for flexible adjustment of the internal space of the isolation cover, meeting the space requirements of rice at different growth stages and avoiding space waste or insufficient space.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A rice breeding isolation cover for a rice breeding rack includes a base, on which a support rod is mounted. The support rod has a square cross-section and a connecting ring is fitted onto the support rod. A support frame, also square in structure, is fixedly connected to one side of the connecting ring. Multiple support frames and connecting rings are provided, and the multiple support frames are evenly distributed longitudinally. A plastic film tube is fitted onto each of the multiple support frames and is fixedly connected to the support frame. The bottom of the plastic film tube is connected to the base. A sealing cap is provided on the uppermost support frame, and a support assembly is provided between adjacent support frames.

[0007] More preferably, the plastic film tube has open ends, a square cross-section, and is made of transparent PVC material.

[0008] More preferably, the support assembly includes a connecting shaft, on which a left rod and a right rod are rotatably connected. The connecting shaft is fixedly connected to a connecting ring, and the ends of the left and right rods between two adjacent connecting shafts are rotatably connected.

[0009] More preferably, a connecting seat is fixedly installed on the top of the base, a screw is movably installed on the connecting seat, the screw is arranged parallel to the support rod, a movable seat is threaded onto the screw, and the connecting seat is fixedly connected to the lowermost connecting ring through the lowermost connecting shaft.

[0010] More preferably, the movable seat is fixedly connected to a second connecting ring arranged in a bottom-up order via a connecting shaft.

[0011] More preferably, a support frame is fixedly installed on the base, a rotary motor is fixedly installed on the support frame, the output end of the rotary motor is connected to a screw drive, a limit block is fixedly connected on the support frame, and the screw slides through the limit block.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model uses a rotary motor to drive the screw to rotate. Since the screw is threadedly connected to the movable seat, it can drive the movable seat to move up and down, thereby driving the connecting ring and support frame connected to it to move, realizing flexible adjustment of the internal space of the isolation cover, meeting the space requirements of rice at different growth stages, and avoiding the problem of space waste or insufficient space.

[0014] 2. This utility model uses a plastic film tube made of transparent PVC material, which can ensure good light conditions, provide sufficient light for rice, and is beneficial to the photosynthesis and growth of rice.

[0015] 3. This utility model uses a support assembly consisting of a connecting shaft, a left rod, and a right rod, as well as a limiting block to limit the screw, and a support frame to support the rotating motor and the screw. This makes the entire isolation cover structure stable, effectively resisting the influence of harsh weather conditions, ensuring the stability of the environment inside the isolation cover, and reducing the risk of physical damage to rice plants and isolation failure.

[0025] like Figure 1-4 As shown, a rice breeding isolation cover for a rice breeding rack includes a base 1, on which a support rod 2 is mounted. The support rod 2 has a square cross-section, and a connecting ring 3 is fitted onto the support rod 2. A support frame 4, also square in structure, is fixedly connected to one side of the connecting ring 3. Multiple support frames 4 and connecting rings 3 are provided, and the multiple support frames 4 are evenly distributed longitudinally. A plastic film tube 5 is fitted onto each of the multiple support frames 4, and the plastic film tube 5 is fixedly connected to the support frame 4. The bottom of the plastic film tube 5 is connected to the base 1. A sealing cap 6 is provided on the uppermost support frame 4, and a support assembly 7 is provided between two adjacent support frames 4. This structural design can effectively create a stable isolation space and facilitates the installation and disassembly of the plastic film tube 5, making it easy to replace and maintain.

[0026] The plastic film tube 5 has open ends, a square cross-section, and is made of transparent PVC material. The transparent PVC material ensures good light conditions, providing ample sunlight for the rice, which is beneficial for photosynthesis and growth. It also possesses good flexibility and durability.

[0027] The support assembly 7 includes a connecting shaft 8, on which a left rod 9 and a right rod 10 are rotatably connected. The connecting shaft 8 is fixedly connected to a connecting ring 3, and the ends of the left rod 9 and right rod 10 between adjacent connecting shafts 8 are rotatably connected. This structure effectively enhances the stability between adjacent support frames 4, making the overall structure of the isolation cover more stable. It also ensures that the spacing between adjacent connecting rings 3 is the same.

[0028] A connecting seat 11 is fixedly installed on the top of the base 1. A screw 12 is movably installed on the connecting seat 11. The screw 12 is arranged parallel to the support rod 2. A movable seat 13 is threadedly connected to the screw 12. The connecting seat 11 is fixedly connected to the lowermost connecting ring 3 through the lowermost connecting shaft 8.

[0029] The movable seat 13 is fixedly connected to the second connecting ring 3 arranged in a bottom-to-top order via the connecting shaft 8. The movable seat 13 can be moved up and down by the screw 12, which can adjust the height of some of the connecting rings 3 and the support frame 4 to meet different breeding needs.

[0030] A support frame 14 is fixedly installed on the base 1, and a rotary motor 15 is fixedly installed on the support frame 14. The output end of the rotary motor 15 is connected to the screw 12 for transmission. A limit block 16 is fixedly connected to the support frame 14, and the screw 12 slides through the limit block 16. The rotary motor 15 drives the screw 12 to rotate. Since the screw 12 is threadedly connected to the movable seat 13, it can drive the movable seat 13 to move up and down, thereby driving the connecting ring 3 and the support frame 4 connected to it to move. This allows for flexible adjustment of the internal space of the isolation cover, meeting the space requirements of rice at different growth stages and avoiding space waste or insufficient space.

[0031] Working principle:

[0032] Using this device, rice breeding operations are carried out inside the isolation chamber. Based on the rice growth, the rotary motor 15 is activated to adjust the internal space of the isolation chamber. Activating the rotary motor 15 drives the screw 12 to rotate. Due to the threaded connection between the screw 12 and the movable seat 13, the movable seat 13 moves up and down along the screw 12. When the movable seat 13 moves upward, it drives the connected connecting ring 3 and support frame 4 upward, increasing the distance between adjacent support frames 4 and thus expanding the internal space of the isolation chamber. Conversely, when the movable seat 13 moves downward, it shrinks the internal space of the isolation chamber. Because the multiple connecting rings 3 are connected by the connecting shaft 8, left rod 9, and right rod 10, the multiple connecting rings 3 move simultaneously, changing the distance between adjacent connecting rings 3 at the same time.
