Description

Technical Field

[0001] The invention relates to the technical field of plant cultivation, in particular to a plant cultivation box capable of adjusting light wavelength bands. Background Art

[0002] At present, there is a great demand for agricultural products in China, and the problem of arable land is becoming increasingly serious. Based on this situation, soilless cultivation technology has developed rapidly in recent years, and plant cultivation cabinets are important equipment. However, the common plant cultivation cabinets currently use simple lighting to simulate the environment under the sun to make plants photosynthesize, but simply simulating the simplest light cannot achieve the best photosynthesis of plants. This is because the photosynthesis of plants depends on light and pigments, and the absorption spectra of various pigments are not the same. For example, chlorophyll a and b mainly absorb red, orange, blue, and purple light, carotenoids absorb blue-violet light, and green light is the color light with the lowest absorption rate of various pigments. In addition, different plants have different light sensitivity at different production stages. Plants need to absorb different types of wavelengths of light, so simple light cannot make plants grow in the best state.

[0003] The inventors found in their research that the plant incubators in the prior art have at least the following disadvantages:

[0004] During the plant growth process, the lighting effect is not adaptively adjusted according to the plant's growth stage, resulting in low plant growth efficiency. Summary of the invention

[0005] The purpose of the present invention includes, for example, providing a plant cultivation box with adjustable light band, which can adjust the lighting effect as needed to meet the needs of plants at different stages for light of different wavelengths, thereby improving the growth effect of plants.

[0006] The embodiments of the present invention can be implemented as follows:

[0009] In an optional embodiment, the wavelength adjustment component includes a driving unit and a plurality of wavelength adjusters, the driving unit is mounted on the incubator body, the plurality of wavelength adjusters are all mounted on the driving unit, and the driving unit is used to drive the plurality of wavelength adjusters to move relative to the light source so that the light source can selectively dock with one of the plurality of wavelength adjusters.

[0010] Based on the above scheme, the driving unit drives multiple wavelength adjusters to move, realizes the automatic adjustment of the position of the wavelength adjusters, reduces the difficulty of operation, and improves the adjustment efficiency. In addition, one of the multiple wavelength adjusters can cooperate with the light source to obtain light of the corresponding wavelength, which is beneficial to the growth of plants in the culture chamber.

[0011] In an optional embodiment, the driving unit includes a motor and a mounting bracket, the motor is fixed to the incubator body, the mounting bracket is connected to the output shaft of the motor, the multiple wavelength adjusters are all fixed to the mounting bracket and are arranged at intervals around the output shaft of the motor, and the motor is used to drive the mounting bracket to rotate, so as to drive the multiple wavelength adjusters to rotate.

[0043] In the prior art, when cultivating plants indoors, light needs to be provided for a long time, but the wavelength of the light cannot be flexibly adjusted, and the needs of different plants or the same plant at different stages for light of different wavelengths cannot be met, which is not conducive to the growth of plants.

[0044] In view of this, the designer provides a plant incubator with adjustable light band, which can adjust the wavelength of light as needed to meet the growth needs of plants and facilitate plant growth.

[0045] Please refer to Figure 1-Figure 5 This embodiment provides a plant cultivation box with adjustable illumination wavelength band, including a cultivation box body 100, a positioning mechanism 200 and an illumination mechanism 300. The cultivation box body 100 is provided with a cultivation chamber 101, the positioning mechanism 200 is installed in the cultivation chamber 101, and the positioning mechanism 200 is used to locate the plants to be cultivated; the illumination mechanism 300 includes a light source 310 and a wavelength adjustment component 320, both of which are installed in the cultivation box body 100, and the wavelength adjustment component 320 cooperates with the light source 310 to adjust the wavelength of the light beam emitted by the light source 310 to the cultivation chamber 101.

[0046] As described above, the plant cultivation box with adjustable light band provided in this embodiment works as follows:

[0047] By adjusting the positions of the multiple wavelength adjustment components 320 of the illumination mechanism 300, the light from the light source 310 can enter the culture chamber 101 through the corresponding wavelength adjustment components 320, providing illumination of a set wavelength for the plants in the culture chamber 101. The wavelength of illumination can be adjusted as needed according to the different growth stages and types of the plants, thereby facilitating plant growth.

[0048] The following embodiments illustrate the details of the plant cultivation box with adjustable light wavelength of the present application by way of examples.

[0049] Please refer to Figure 1-Figure 5 In this embodiment, optionally, the wavelength adjustment component 320 includes a driving unit 321 and a plurality of wavelength adjusters 322. The driving unit 321 is installed on the incubator body 100, and the plurality of wavelength adjusters 322 are all installed on the driving unit 321. The driving unit 321 is used to drive the plurality of wavelength adjusters 322 to move relative to the light source 310 so that the light source 310 can selectively dock with one of the plurality of wavelength adjusters 322.

[0050] It should be understood that the driving unit 321 drives the multiple wavelength adjusters 322 to move, thereby realizing automatic adjustment of the position of the wavelength adjusters 322, reducing the difficulty of operation and improving the adjustment efficiency. Moreover, one of the multiple wavelength adjusters 322 can cooperate with the light source 310 to obtain light of a corresponding wavelength, which is beneficial to the growth of the plants in the culture chamber 101.

[0051] Optionally, the driving unit 321 includes a motor 3211 and a mounting bracket 3212, the motor 3211 is fixed to the incubator body 100, the mounting bracket 3212 is connected to the output shaft of the motor 3211, and multiple wavelength adjusters 322 are fixed to the mounting bracket 3212 and arranged at intervals around the output shaft of the motor 3211. The motor 3211 is used to drive the mounting bracket 3212 to rotate, so as to drive the multiple wavelength adjusters 322 to rotate.

[0052] It is worth noting that the multiple wavelength adjusters 322 are all installed on the mounting frame 3212, the positions of the multiple wavelength adjusters 322 are stable, and the relative positions of the multiple wavelength adjusters 322 are fixed and not easy to move, which makes it easy to flexibly adjust the positions of the wavelength adjusters 322 through set strategies, and the regulation is convenient and fast.

[0053] It should be understood that the mounting frame 3212 can be an annular frame, and the number of wavelength adjusters 322 is multiple, and the multiple wavelength adjusters 322 are arranged in an annular shape on the mounting frame 3212. Specifically, the multiple wavelength adjusters 322 are arranged in a circular ring. Driven by the motor 3211, each wavelength adjuster 322 can move to a position docking with the light source 310, so as to filter the light of different wavelengths of the light source 310.

[0054] Please refer to Figure 1-Figure 5Optionally, the wavelength adjuster 322 includes a light shielding tube 3221 and a filter 3222. The light shielding tube 3221 is provided with a light path transmission channel with both ends open. The filter 3222 is installed in the light path transmission channel. The light shielding tube 3221 is connected to the mounting frame 3212. One end of the light shielding tube 3221 is used to connect with the light source 310, and the other end of the light shielding tube 3221 is used to communicate with the culture chamber 101. The light shielding tube 3221 can be a cylinder or a rectangular tube. The filter 3222 can be bonded or screwed in the light shielding tube 3221. The filter 3222 mainly allows the light of the corresponding wavelength to pass through, so as to be emitted from the light shielding tube 3221 into the culture chamber 101, so as to effectively illuminate the plants. The light beam adjustment structure is simple and the cost is low.

[0055] In this embodiment, optionally, a light hole 102 connected to the culture chamber 101 is provided on the culture box body 100; an elastic light shielding cover 110 is installed on the culture box body 100, and the elastic light shielding cover 110 has a first end and a second end opposite to each other in a preset direction, the first end is connected to the light hole 102; the second end is used to connect with an end of the light shielding tube 3221 away from the light source 310; and the second end has a tendency to move away from the first end, so that the second end is pressed against the light shielding tube 3221. By connecting the culture box body 100 and the wavelength adjuster 322 through the elastic light shielding cover 110, the gap between the light shielding tube 3221 and the elastic light shielding cover 110 can be reduced or even zero, so as to prevent external light from entering the culture chamber 101 from the joint between the two, thereby ensuring that the culture chamber 101 mainly enters the light of the corresponding wavelength, and ensuring the smooth growth of the plants.

[0057] It should be understood that the foldable cylinder 111 can be folded and retracted along its own axial direction, and after the foldable cylinder 111 is folded, the elastic reset member 113 is compressed, and has an elastic force to lengthen the foldable cylinder 111. When the light-shielding cylinder 3221 moves between the docking plate 112 and the light source 310, the foldable cylinder 111 and the elastic reset member 113 are both compressed, and under the action of the elastic force, the docking plate 112 and the light-shielding cylinder 3221 are in close contact, and the gap between the two is small, and it is not easy to let light through, and it is safe to use.

[0058] Furthermore, the docking plate 112 includes a hollow plate body 1121, a first guide plate 1122 and a second guide plate 1123. The hollow plate body 1121 is installed and connected to the second end of the foldable cylinder 111. The first guide plate 1122 and the second guide plate 1123 are both installed on the hollow plate body 1121 and distributed on two opposite sides of the hollow plate body 1121. The plate surfaces of the first guide plate 1122 and the second guide plate 1123 facing away from the incubator body 100 are both set as guide slopes, and the distance between the guide slope and the incubator body 100 gradually decreases in the direction from the side where the guide slope is connected to the hollow plate body 1121 to the other side, so that the guide slope can guide the light-shielding cylinder 3221 to dock with the hollow plate body 1121.

[0059] It is worth noting that the docking plate 112 is set as a special-shaped plate, and part of the docking plate 112 is provided with a guide slope, so that the light-shielding tube 3221 can be guided to enter the hollow plate body 1121, so that the light-shielding tube 3221 can be docked with the hollow plate body 1121 and the light source 310 at the same time, preventing the light-shielding tube 3221 from interfering with the docking plate 112 and the light source 310 when it rotates toward the docking plate 112.
