Abstract
Description
Technical Field
[0001] This utility model relates to the field of plant cultivation and maintenance technology, and in particular to a fixed maintenance device for grafted plants grown in greenhouses. Background Technology
[0002] Greenhouse grafting is a technique for grafting plants in a controlled environment, widely used in agriculture and horticulture. By grafting in a greenhouse, environmental conditions such as temperature, humidity, and light can be better controlled, improving the grafting survival rate and accelerating plant growth. After grafting, the grafted seedlings need to be supported and fixed to ensure their survival rate and healthy growth. To prevent damage to the grafting site from wind or other external forces, thin bamboo poles or wooden sticks are usually inserted next to the grafted seedlings, and the plants are gently tied to simple supports to provide additional support. This method requires the support specifications to correspond one-to-one with the grafted seedlings, which cannot flexibly adapt to the support needs of grafted seedlings of different sizes. Furthermore, the stability of using a single support is limited, which may cause the grafted seedlings to fall over, which is not conducive to their growth and development.
[0003] To address the aforementioned issues, a fixed maintenance device has been developed for grafting and cultivation in greenhouses. Utility Model Content

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0018] A type of fixed maintenance device for grafted plants grown in greenhouses, such as Figures 1-3 As shown, the device includes a first fixed rod 1, with three limiting members 12 slidably connected to the first fixed rod 1. Each limiting member 12 is connected to the first fixed rod 1 by a spring 13. A second fixed rod 2 is slidably connected to the first fixed rod 1. Limiting grooves are provided on the upper left and right sides of both the first and second fixed rods 1 and 2. A limiting hole is provided on the second fixed rod 2, allowing the limiting members 12 to engage with the limiting hole. A mounting member 3 is connected to the lower part of the first fixed rod 1. A worm gear 4 is rotatably connected to the right side of the mounting member 3. An assisting member is provided on the rear side of the worm gear 4. A connecting rod 5 is also connected to the lower part of the first fixed rod 1. The connecting rod 5 is located below the mounting member 3. A worm wheel 6 is connected to the right side of the connecting rod 5. The left and right sides of the connecting rod 5... Each of the first and second fixing rods is rotatably connected to a ground nail 7, which has a threaded structure to enhance stability in contact with the soil. Each ground nail 7 is threadedly connected to a stabilizing member 8, which has a structure that is narrower at the top and wider at the bottom. Rotating plates 9 are rotatably connected to the upper left and right sides of the first fixing rod 1 and the second fixing rod 2. Each rotating plate 9 has a hook 10 hanging on the front. Each of the first fixing rod 1 and the second fixing rod 2 is equipped with an adjustment component 11, which includes an adjustment knob and a pull rope. Each of the first fixing rod 1 and the second fixing rod 2 is equipped with an adjustment knob, which has anti-slip texture. A pull rope is fitted between the adjustment knob and the adjacent rotating plate 9, and one end of the pull rope is fixed to the adjacent adjustment knob.
[0019] It should be noted that greenhouse grafting is a plant grafting technique performed in a controlled environment, widely used in agriculture and horticulture. Grafting within a greenhouse allows for better control of environmental conditions such as temperature, humidity, and light, improving graft survival rates and accelerating plant growth. After grafting, the grafted seedlings need to be supported and secured to ensure survival and healthy growth. First, the ground nails 7 are inserted into the soil around the seedling. The threaded structure of the ground nails 7 enhances their grip. Then, the stabilizing component 8 is rotated to bring it into contact with the soil surface, increasing the contact area between the device and the ground, thus enhancing the overall stability of the device. Since the grafting angle of the seedling is not fixed, an assistive component can be used to rotate the worm gear 4, causing the worm wheel 6 to rotate, thereby connecting the connecting rod 5 and the first fixing rod 1. The second fixing rod 2 can be adjusted according to the actual grafting angle of the grafted seedling. Then, slide the second fixing rod 2 so that the limiting member 12 slides backward and the adjacent spring 13 is compressed. Then, adjust the second fixing rod 2 to a suitable position according to the actual grafting height of the grafted seedling. When the limiting hole corresponds to the limiting member 12, the limiting member 12 returns to its original position under the action of the spring 13, so that the limiting member 12 is engaged in the limiting hole, thereby completing the adjustment of the fixed height of the device. This method can flexibly adapt to the fixing needs of grafted seedlings with multiple grafting heights and angles. Then, fix the grafted seedling with the hook 10 and rotate the adjustment knob to adjust the hanging rope to a suitable length, thereby adjusting the opening and closing angle of the rotating plate 9, so as to adjust the grafted seedling to a suitable position for receiving and fixing, which is beneficial to the growth and development of the grafted seedling.
