[0001] This invention relates to the field of maize breeding technology, and in particular to an adjustable-angle light simulation box for maize breeding. Background Technology

[0002] Maize breeding refers to a systematic technical process aimed at ensuring food security and meeting the needs of agricultural production and the market. It involves using scientific methods to screen and regulate maize genetic material to cultivate new varieties with superior traits. Its core focus is on improving key maize traits, including increasing yield, enhancing stress resistance, improving quality, and optimizing agronomic traits.

[0003] The light simulation chamber for maize breeding is a specialized experimental device designed specifically for the maize breeding process. It can precisely control light and related environmental parameters. Its core function is to create a stable and repeatable growth environment for maize breeding materials by artificially simulating the intensity, duration, and spectral characteristics of natural light. This eliminates interference factors such as unstable light, seasonal limitations, and extreme climates in the natural environment, thus supporting breeding research and screening work.

[0004] Traditional light simulation boxes used for maize breeding typically have fixed light sources that cannot be adjusted in angle, resulting in insufficient light coverage of the maize seeds and thus affecting breeding quality. Summary of the Invention

[0005] To address or partially address the problems existing in related technologies, this invention provides an adjustable-angle light simulation box for maize breeding, aiming to provide a light simulation box with adjustable light angle.

[0006] The aforementioned adjustable-angle light simulation box for maize breeding includes a box body, an opening and closing door, and a seedling box. The opening and closing door is provided on one side of the box body, and the seedling box is provided at the bottom of the box body. A light panel is provided inside the box body above the seedling box, and a plant growth lamp tube is provided on the lower side of the light panel. Cylindrical connecting columns are provided at both ends of the plant growth lamp tube. A reflector is provided above the plant growth lamp tube.

One end of the filter cover is rotatably connected to the connecting column, and the other end is rotatably connected to the rotating sleeve. A second locking mechanism is provided.

[0007] In some designs, the filter is a hollow prism, with each side capable of transmitting light of different wavelengths.

[0008] In some designs, the filter is in the form of a hollow triangular or quadrangular prism.

[0009] In some solutions, the first locking mechanism and the second locking mechanism have the same structure; Includes knobs, trapezoidal blocks, buttons, and springs; The knob has a clearance hole in the middle, and a mounting groove is constructed on the side wall of the clearance hole. Two arc-shaped locking pieces are provided in the mounting groove. The bottom of the mounting slot is provided with a mounting hole, which extends radially along the knob and passes through the knob. A trapezoidal block is slidably mounted in the mounting hole, and a button is provided on the trapezoidal block. The two locking pieces are arranged in a circle, with one adjacent end hinged to the knob and the other adjacent end abutting against the two inclined surfaces of the trapezoidal block, and driven to move closer to each other by a spring.

[0010] In some designs, the end of the locking piece that contacts the trapezoidal block is cylindrical.

[0011] In some designs, the plant growth lamp is positioned perpendicular to the opening / closing door; and both the first locking mechanism and the second locking mechanism are positioned close to the opening / closing door.

[0012] In some designs, the inner top of the housing is provided with a guide tube, and the lamp plate is provided with a guide rod, the guide rod extending into the guide tube; A drive mechanism for moving the lamp panel up and down is provided between the inner top of the housing and the lamp panel.

[0016] The technical solution provided by this invention may include the following beneficial effects: This application incorporates a reflector on the plant growth lamp tube. By adjusting the angle of the reflector, the illumination angle of the plant growth lamp tube can be adjusted, thereby achieving adjustable illumination angle and effectively ensuring that the light can fully cover the corn seeds, thus guaranteeing breeding quality.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited to the content described.

[0023] like Figures 1-6 As shown, this application provides an adjustable angle lighting simulation box for corn breeding, including a box body 1, an opening and closing door 101, and a seedling box 2. The opening and closing door 101 is provided on one side of the box body 1, and the seedling box 2 is provided at the bottom of the box body 1. A light panel 3 is provided inside the box body 1 above the seedling box 2. Plant growth lamps 4 are provided on the lower side of the light panel 3. There are multiple plant growth lamps 4 so that the light emitted by the plant growth lamps 4 can cover all areas of the seedling box 2. Cylindrical connecting posts 401 are provided at both ends of the plant growth lamps 4. The connecting posts 401 have a multi-layer structure with a copper core in the center, which is used to connect an external power source so that the plant growth lamps 4 can emit light. The outer side of the copper core is a connecting layer made of wear-resistant and non-conductive material.

[0024] A reflector 5 is provided above the plant growth lamp tube 4. The reflector 5 is roughly arc-shaped. When the light from the plant growth lamp tube 4 shines on the reflector 5, the light is reflected and shines downwards in parallel, thus confining the light emitted by the plant growth lamp tube 4 to a certain range and shining downwards. One end of the reflector 5 is rotatably connected to the connecting post 401, and the other end is provided with a rotating sleeve 501, which is rotatably mounted on the connecting post 401. The end of the rotating sleeve 501 is provided with a first locking mechanism 7. In this way, when the reflector 5 is rotated, the direction of illumination from the plant growth lamp tube 4 will change, thereby achieving the problem of adjusting the illumination angle of the light source and effectively ensuring that all seeds in the seedling box 2 can be illuminated. After the position of the reflector 5 is adjusted, it is locked by the first locking mechanism 7 to ensure that the illumination angle will not change during the seedling process.

[0025] The reflector 5 and the plant growth lamp 4 are disposed inside the filter 6. One end of the filter 6 is rotatably connected to the connecting post 401, and the other end is rotatably connected to the rotating sleeve 501, and is provided with a second locking mechanism 8. When the plant growth lamp 4 emits light, the light is reflected by the reflector 5 and shines downwards. During this process, the light passes through the filter 6, which filters out part of the light, so that only the light effective for breeding can pass through the filter 6 and shine on the corn seeds, effectively improving seedling efficiency.

[0026] The process of using this application is as follows: Place corn seeds in the seedling box 2, then turn on the plant growth lamp 4. The plant growth lamp 4 emits light, and part of the light shines directly downwards onto the seeds in the seedling box 2. The other part of the light is reflected by the reflector 5 and then shines downwards onto the seeds in the seedling box 2. When it is necessary to adjust the illumination angle of the plant growth lamp 4, first release the lock of the first locking mechanism 7, then rotate the reflector 5. After adjusting the illumination angle, lock the position of the reflector through the first locking mechanism 7.

[0027] During the downward illumination of light, the light passes through the filter 6, which filters out other light rays, ensuring that only the light beneficial to seed growth shines on the seeds, thereby effectively improving seedling efficiency.

[0028] In some specific embodiments, the filter 6 is a hollow prism, and each side can transmit light of different wavelengths. By rotating the filter 6, different sides are placed in the path of light, and the light illuminating the seedling box 2 is different, so that the device can be used for different crop breeding and improve the applicability of the device.

[0029] In this embodiment, the filter 6 is in the shape of a hollow triangular prism or a quadrangular prism.

[0030] In this embodiment, as Figure 4 and Figure 5 As shown, the first locking mechanism 7 and the second locking mechanism 8 have the same structure.

[0031] Includes knob 701, trapezoidal block 702, button 703, and spring 704; One side of the knob 701 is fixedly connected to one end of the rotating sleeve 501 or the filter cover 6. The knob 701 has a clearance hole 7011 in the middle. The connecting post 401 or the rotating sleeve 501 is fitted into the clearance hole 7011. The side wall of the clearance hole 7011 is constructed with a mounting groove 7012. The mounting groove 7012 is provided with two arc-shaped locking pieces 705. The bottom of the mounting groove 7012 is constructed with a mounting hole. The mounting hole extends along the radial direction of the knob 701 and passes through the knob 701. A trapezoidal block 702 with a larger top and a smaller bottom is slidably installed in the mounting hole. A button 703 is provided on the trapezoidal block 702. The upper end of the button 703 extends outward from the mounting hole onto the outer surface of the knob 701.

[0032] The two locking plates 705 are arranged in a circle. One adjacent end is hinged to the knob 701, and the other adjacent end abuts against the two inclined surfaces of the trapezoidal block 702. They are driven to move closer to each other by a spring 704. Specifically, the two ends of the spring 704 are hinged to one end of the two locking plates 705. Under normal conditions, the spring 704 is tightened, so that the two locking plates 705 hold the connecting post 401 or the rotating sleeve 501 tightly, thereby preventing the reflector 5 or the filter 6 from rotating.

[0033] When button 703 is pressed down, button 703 moves trapezoidal block 702 downward, trapezoidal block 702 opens the ends of the two locking pieces 705 to both sides, thereby separating the locking pieces 705 from the connecting post 401 or rotating sleeve 501.

[0034] Thus, when rotating the reflector 5 or the filter 6, simply press down the button 703 and then rotate the corresponding knob 701 to adjust the reflector 5 or the filter 6. At the same time, when adjusting the reflector 5, since the filter 6 is still held by the rotating sleeve 501 by the second locking mechanism 8, the filter 6 will rotate accordingly. This effectively avoids the problem of having to adjust the filter 6 when only adjusting the reflector 5, thus improving the convenience of using the device.

[0035] In this embodiment, the end of the locking piece 705 that contacts the trapezoidal block 702 is cylindrical, which helps to reduce the friction between the locking piece 705 and the side of the trapezoidal block 702, thereby reducing wear on both and improving the service life of the device. At the same time, after releasing the button 703, it effectively ensures that the trapezoidal block 702 can rise and reset smoothly.

[0036] In some specific embodiments, the plant growth lamp tube 4 is arranged perpendicular to the opening and closing door 101, and the first locking mechanism 7 and the second locking mechanism 8 are both arranged close to the opening and closing door 101; so that the staff can adjust the reflector 5 and the filter 6 by opening the opening and closing door 101, making it more convenient to use.

[0037] In some specific implementations, such as Figure 1 As shown, the top of the inner part of the housing 1 is provided with a guide tube 102, and the lamp plate 3 is provided with a guide rod 301. The guide rod 301 extends into the lamp plate 301. Through the guide tube 102 and the guide rod 301, the lamp plate 3 is limited so that the lamp plate 3 can only move up and down.

[0038] A drive mechanism 9 for driving the lamp panel 3 to move up and down is provided between the inner top of the housing 1 and the lamp panel 3.

[0039] When the height of the lamp panel 3 needs to be adjusted, the drive mechanism 9 is activated, thereby driving the lamp panel 3 to move up and down, thus adjusting the height of the lamp panel 3, that is, adjusting the height of the plant growth lamp tube 4.

[0040] In this embodiment, as Figure 6 As shown, the driving mechanism 9 includes a connecting plate 901, a linear driving element 902, a slider 903, and a guide wheel 904; The lamp plate 3 is provided with two parallel connecting plates 901. The connecting plates 901 are provided with sliding grooves 9011, which are approximately Z-shaped. The slider 903 is slidably installed on the inner top of the housing 1 and is driven to move by a linear drive element 902, and is located between the two connecting plates 901. Guide wheels 904 are rotatably installed on both sides of the slider 903, and the guide wheels 904 are embedded in the sliding grooves 9011.

[0041] Thus, when the linear drive element 902 is activated, it drives the slider 903 to slide, thereby causing the guide wheel 904 to move along the slide groove 9011. Since the height of the guide wheel 904 remains unchanged, the slider 903 drives the lamp plate 3 to move up and down.

[0042] In this embodiment, the linear drive element 902 is an electric telescopic rod or a cylinder.

[0043] In some specific embodiments, the seedling box 2 is slidably installed at the bottom of the box body 1, and the front end of the seedling box 2 is provided with a handle, making it more convenient to pull out and put in the seedling box 2.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
