Description

Technical Field

[0001] The present invention relates to the technical field of seedling cultivation, and specifically relates to a forestry seedling cultivation device. Background Art

[0002] Seedling cultivation refers to cultivating seedlings in a nursery, hotbed or greenhouse for transplanting into the land. It is mainly to better meet the growth needs of seedlings, improve the efficiency and quality of seedling cultivation, and adapt to different seedling cultivation environments and goals. Existing forestry seedling cultivation devices are usually divided into seedling beds and seedling trays. A seedling tray refers to a tray with multiple small grids for planting seeds or seedlings, which is convenient for management and transplantation.

[0003] For example, Chinese Patent No. CN119631761A discloses a forestry seedling cultivation device, including a seedling tray. A plurality of placement holes are evenly arranged on the seedling tray. Installation grooves are arranged on both the front and rear sides of each row of placement holes. Installation holes communicating with the placement holes are arranged on the installation grooves. Removable cutting bag components can be installed in the front and rear installation grooves of the placement holes in the same row. The cutting bag component includes a support rod, a handle, a mounting block and a blade. The support rod is arranged in the installation groove. There are two handles which are respectively installed at both ends of the support rod. The number of mounting blocks and blades is equal to the number of placement holes in the same row. The mounting block is slidably connected to the installation hole. One end of the mounting block is connected to the support rod, and the other end of the mounting block is connected to the blade. The cutting bag component in the present invention can cut open the seedling bag during the lifting process, which is convenient for removing the seedling bag during transplantation. Of course, if a decomposable seedling bag is used, the seedling bag does not need to be removed, and the root system of the sapling can grow out from the separated part to ensure the growth of the sapling.

[0004] However, the above scheme still has problems in traditional equipment that the sunshade board and irrigation valve need to be adjusted manually respectively, with low efficiency and easy to cause problems such as water evaporation or uneven light, and it is impossible to adjust the irrigation amount synchronously according to the light intensity of the saplings. When the light intensity is high and the soil evaporation is large, the irrigation amount cannot be increased in time, which may lead to the death of the saplings due to water shortage. When both the light intensity and the soil evaporation are low, the irrigation amount needs to be reduced in time to avoid the air in the soil being squeezed out, resulting in the lack of oxygen in the root system of the saplings.

[0014] Preferably, a rotating shaft is fixedly installed on one side of the shaft frame through which the rotating shaft of the cam passes. Both sides of the sunshade are fixedly connected to the rotating shaft. A fixed ring is fixedly installed on the side wall of the shaft frame. A hydraulic wheel fixedly connected coaxially with the rotating shaft is arranged in the fixed ring. A rotating plate is fixedly installed on the outer wall of the hydraulic wheel. A fixed plate is fixedly installed on the inner wall of the fixed ring.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] Second, the sliding box that adjusts up and down reciprocally can also adjust the pressure on the bottom surface of the seedling cultivation box in the sliding box. When the liquid level height in the sliding box is higher, the pressure on the bottom surface of the seedling cultivation box is greater, and vice versa, the pressure on the bottom surface of the seedling cultivation box is smaller. That is, when the soil evaporation rate changes greatly or rapidly, the irrigation amount can be immediately adjusted accordingly, so that the soil evaporation rate and the irrigation amount are non-linearly coupled, further improving the survival rate of the seedlings or seeds.

[0022] III. When the present invention drives the sunshade to change color and adjust through the color-changing component, the hydraulic wheel can also be used to drive the sunshade to increase the incident angle and reflection amount of the light irradiating the sunshade at the same time. Meanwhile, the rotating shaft drives the cam to adjust the irrigation rate of the irrigation component, so that the adjustment of the color-changing component, the irrigation amount of the irrigation component, and the refraction ability of the sunshade change linearly and synchronously. Then, the humidity sensor is used to drive the sliding box to non-linearly adjust the irrigation amount of the irrigation component through the electromagnet, further improving the coupling between the components and reducing the impact of the external environment temperature on the growth and development of seeds or seedlings.

Specific implementation mode

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1 to 11 , the present invention provides a technical solution: a forestry seedling cultivation device, including a base 1, a seedling tray 7 is fixedly installed above the base 1 through an installation groove, a plurality of seedling boxes are arranged in the seedling tray 7, and a transparent sunshade 5 is arranged above the seedling tray 7;

[0037] It also includes a color-changing component that can gradually change the color of the sunshade 5 according to the light intensity to adjust the light-shielding ability of the sunshade 5 to sunlight;

[0038] It also includes an irrigation component for drip irrigation of the saplings in the seedling box and can synchronously adjust the drip irrigation rate when the color-changing component adjusts the light-shielding ability of the sunshade 5 to sunlight.

[0039] When this device is in use, first, put appropriate soil into the seedling-growing box inside the seedling tray 7, bury the seeds into the soil and compact it. Then, pour an appropriate amount of water into the seedling-growing box, and place the seedling tray 7 under the sunshade 5, so that sunlight can pass through the sunshade 5 to irradiate the seeds in the seedling-growing box, thereby promoting the respiration of the seeds, activating the enzymes in the seeds, and accelerating the germination process. When the sunlight intensity changes, the color-changing component can gradually change the color of the sunshade 5 according to the sunlight intensity. For example, when the sunlight intensity is relatively low in the early morning or evening, the color of the sunshade 5 is lighter at this time, and the light-shielding ability of the sunshade 5 to sunlight is reduced. While when the sunlight intensity is relatively high at noon or in the afternoon, the color of the sunshade 5 is darker at this time, and the light-shielding ability of the sunshade 5 to sunlight is stronger, so that the sapling seeds can always maintain an appropriate sunlight intensity when the sunlight intensity changes. At the same time, irrigate the seeds in the seedling-growing box through the irrigation component. When the sunlight intensity changes, the external environmental temperature also changes synchronously at this time. For example, the external air temperature is relatively high at noon or in the afternoon. At this time, the transpiration of the soil is relatively strong. To avoid excessive evaporation of water in the soil from affecting the germination or growth of the seeds, the drip irrigation rate for the seedling-growing box can be increased through the irrigation component. While when the external environmental temperature decreases and the transpiration of the soil weakens, the irrigation component reduces the drip irrigation rate for the seedling-growing box, so that the irrigation flow rate, the sunlight intensity, and the sunshade ability of the sunshade 5 achieve dynamic coupling, ensuring that the development environment of the seeds or seedlings always remains suitable, thereby improving the germination rate and survival rate of the seeds or seedlings.

[0040] In this way, through the cooperation between the color-changing component and the irrigation component, the change of the external sunlight intensity changes the light-shielding ability of the sunshade 5 by adjusting the color of the sunshade 5, and cooperates with the irrigation component to synchronously adjust the drip irrigation rate for the seeds or seedlings, so that the irrigation flow rate, the sunlight intensity, and the sunshade ability of the sunshade 5 achieve dynamic coupling, ensuring that the development environment of the seeds or seedlings always remains suitable, thereby improving the germination rate and survival rate of the seeds or seedlings.

[0041] To avoid the influence of extreme environments on the development of seeds or seedlings. For example, at night, the sunlight intensity is extremely low but the soil evaporation rate is extremely high, or during the rainy season, the sunlight intensity is high but the air humidity is high and the soil evaporation has no effect on the seeds or seedlings. To avoid phenomena such as water shortage and drying up or waterlogging and lack of oxygen for the seeds or seedlings, a humidity detection device can also be set in the seedling tray 7, and the irrigation component can be forcibly turned on or off when the soil humidity in the seedling-growing box reaches the preset value, ensuring that the seeds or seedlings are in a suitable development environment.

[0042] Further, the color-changing component includes a hydraulic tank 2 fixedly installed on one side of the base 1 through a bracket, and a liquid storage tank 3 is fixedly installed on the other side of the base 1 through a bracket. A hydraulic plate 22 is slidably installed in the hydraulic tank 2, and a transparent floating plate 9 is slidably installed in the sunshade 5. A dark liquid is provided in the hydraulic tank 2, and the hydraulic tank 2 is connected to the inside of the sunshade 5 below the floating plate 9 through a hose. A transparent colorless liquid is provided in the sunshade 5 above the floating plate 9, and the inside of the sunshade 5 above the floating plate 9 is connected to the liquid storage tank 3 through a hose;

[0043] The color-changing component further includes a driving component for driving the hydraulic plate 22 to slide vertically up and down reciprocally in the hydraulic tank 2 for adjustment.

[0044] According to the above embodiments, a specific embodiment of the color-changing component is provided. Specifically, refer to Figure 2 , when the external light intensity changes, the driving component drives the hydraulic plate 22 to slide vertically up and down reciprocally in the hydraulic tank 2 for adjustment. When the external light intensity is high, the hydraulic plate 22 moves downward, pressing the dark liquid (such as dyed alcohol or kerosene, etc.) in the hydraulic tank 2 into the sunshade 5, causing the floating plate 9 to move upward. At this time, the transparent colorless liquid (such as brine) above the floating plate 9 is pressed into the liquid storage tank 3. As the light intensity increases, more and more dark liquid enters the sunshade 5, and the sunshade layer formed by the dark liquid becomes thicker and thicker, and the ability to block sunlight becomes higher and higher. When the external light intensity decreases, at this time, the hydraulic plate 22 moves upward, sucking the dark liquid below the floating plate 9 into the hydraulic tank 2, and the light-shielding ability of the sunshade 5 can be gradually reduced.

[0045] In this way, by driving the hydraulic plate 22 to slide vertically up and down reciprocally in the hydraulic tank 2 through the driving component, the ratio between the transparent colorless liquid and the dark liquid in the sunshade 5 is changed, so that the sunlight always maintains an appropriate light intensity, thereby improving the survival rate of seeds or seedlings.

[0046] It is worth mentioning that since both dyed alcohol and kerosene have the characteristics of heat absorption and expansion, when the dark liquid in the sunshade 5 is exposed to high-intensity light, it can accelerate the color adjustment speed of the color-changing component to the sunshade 5 through its own expansion, improving the sensitivity of the device to light intensity. At the same time, the sunshade 5 can be set in the shape of an arch or a concave lens, etc., so that the refraction of light after entering the sunshade 5 can be used to further avoid direct sunlight on the seeds or seedlings, and the shape of the sunshade 5 can be selected according to the characteristics of seeds or seedlings in different latitudes or different seasons.

[0047] Further, the irrigation assembly includes a bottom cavity 11 formed in the base 1. An irrigation pipe 10 is fixedly installed in the bottom cavity 11. The irrigation pipe 10 is connected to the bottom end of the seedling-growing box in the seedling-growing tray 7 through small holes, and capillary cores are provided in the small holes. Shaft brackets 4 are fixedly installed on both sides of the base 1. A sliding cavity is formed in the shaft bracket 4. A sliding box 17 capable of reciprocating up and down for adjustment is installed in the sliding cavity. The bottom end of the sliding box 17 is connected to the irrigation pipe 10 through a pipe buried in the shaft bracket 4. The top end of the sliding box 17 is connected to the outside through an air inlet pipe 16 buried in the shaft bracket 4. The sliding box 17 is connected to an external water supply device. A rotatable cam 14 is installed in a rotating groove formed in the shaft bracket 4, and the cam 14 can contact and press against the air inlet pipe 16.

[0048] According to the above embodiments, a specific embodiment of an irrigation assembly is provided. Specifically, refer to Figure 4 , when the external environmental temperature changes, the cam 14 can be driven to rotate by an external structure at this time. When the cam 14 presses the air inlet pipe 16, the water in the sliding box 17 is affected by the air pressure in the air inlet pipe 16 and cannot enter the seedling-growing box through the irrigation pipe 10, so that the liquid level in the irrigation pipe 10 cannot break through the small holes at the bottom end of the seedling-growing box and enter the seedling-growing box. It can only slowly absorb water through the capillary cores in the small holes to compensate the water in the soil. When the cam 14 gradually disengages from the contact with the air inlet pipe 16, the water in the sliding box 17 enters the seedling-growing box through the water pressure of the communicating vessel formed by the sliding box 17, the irrigation pipe 10 and the seedling-growing box until the water levels in the seedling-growing box and the sliding box 17 are on the same plane. The greater the gas exchange amount outside the air inlet pipe 16, the smaller the influence of the air pressure in the air inlet pipe 16 on the water in the sliding box 17, that is, the drip irrigation flow rate also increases synchronously, and the adjustment of the irrigation rate can be completed. And when the external environmental temperature changes, to avoid insufficient or excessive drip irrigation flow rate, the sliding box 17 that reciprocates up and down for adjustment can also adjust the pressure on the bottom surface of the seedling-growing box in the sliding box 17 at this time. The higher the liquid level in the sliding box 17, the greater the pressure on the bottom surface of the seedling-growing box, and vice versa, the smaller the pressure on the bottom surface of the seedling-growing box. It can immediately follow up the irrigation amount when the soil evaporation amount changes greatly or quickly, so that the soil evaporation amount and the irrigation amount achieve non-linear coupling, and further improve the survival rate of seedlings or seeds.

[0049] Further, a sliding plate 18 is slidably installed on the side wall of the shaft bracket 4. A transmission gear 19 is rotatably installed in an annular groove formed in the shaft bracket 4, and the transmission gear 19 is driven by an external motor. Rack teeth capable of meshing with the transmission gear 19 are provided on the side walls of the sliding plate 18 and the sliding box 17.

[0050] According to the above embodiments, the irrigation rate can be adjusted by rotating the cam 14 in cooperation with the air inlet pipe 16. To prevent excessive water from flowing into the seedling box in the sliding box 17, resulting in too high water content in the soil and excessive oxygen content in the soil, causing phenomena such as oxygen deficiency in the seeds or seedlings. When the external motor drives the transmission gear 19 to rotate, thereby driving the sliding box 17 to slide downward through the rack, the irrigation rate is reduced at this time. At the same time, the transmission gear 19 will also drive the sliding plate 18 to move upward to block the nozzle of the air inlet pipe 16, further reducing the irrigation rate. When the sliding box 17 slides upward, the irrigation demand increases at this time. The sliding box 17 drives the sliding plate 18 to move downward away from the nozzle of the air inlet pipe 16, and the irrigation rate can be further increased;

[0051] Furthermore, a humidity sensor 12 is fixedly arranged at the center position of the seedling tray 7, an electromagnet 20 is arranged on the inner bottom surface of the sliding cavity, and a magnetic plate that can repel the electromagnet 20 is arranged on the bottom surface of the sliding box 17. The electromagnet 20 is electrically connected to the humidity sensor 12 through an electrical signal.

[0052] While adjusting the irrigation rate as described above, in cooperation with the humidity sensor 12, if the external temperature environment rises but the soil evaporation rate does not rise, that is, the humidity sensor 12 detects that the water content in the soil is sufficient. At this time, the electromagnet 20 is used to drive the sliding box 17 to slide downward, driving the sliding plate 18 to block the nozzle of the air inlet pipe 16 to avoid overwatering. When the humidity sensor 12 detects that the water content in the soil is insufficient, the irrigation component can be driven to drip-irrigate the soil when the external environmental temperature has not changed, avoiding the impact of complex environments on the development of seeds or seedlings.

[0053] In this way, through the cooperation between the humidity sensor 12 and the sliding box 17, the irrigation component can provide sufficient water for the soil in a complex environment. That is, when the light environment and the soil evaporation rate change synchronously, the coupling degree of the irrigation amount and the light environment is adjusted by the reciprocating sliding of the sliding box 17 up and down. When the light environment and the soil evaporation rate change inconsistently, the irrigation component can be driven to start or pause by the electromagnet 20, enabling the device to meet complex external environmental changes and expanding the applicable range of the device.

[0054] Furthermore, a rotating shaft 13 is fixedly installed on one side where the rotating shaft of the cam 14 passes through the shaft frame 4. Both sides of the sunshade 5 are fixedly connected to the rotating shaft 13. A fixed ring 6 is fixedly installed on the side wall of the shaft frame 4. A hydraulic wheel 15 coaxially and fixedly connected to the rotating shaft 13 is arranged in the fixed ring 6. A rotating plate 25 is fixedly installed on the outer wall of the hydraulic wheel 15. A fixed plate is fixedly installed on the inner wall of the fixed ring 6. The space between the fixed plate and the rotating plate 25 is connected to the inside of the sunshade 5 above the floating plate 9. The bottom end of the fixed ring 6 is connected to the liquid storage tank 3 through a hose.

[0055] According to the above embodiments, a specific embodiment for driving the rotation of the cam 14 is provided. When the external light environment changes, at this time, the hydraulic plate 22 slides to drive the dark liquid to enter or be sucked out of the hydraulic tank 2, and the transparent colorless liquid in the sunshade plate 5 enters the fixed ring 6 to drive the hydraulic wheel 15 to rotate through pressure, driving the rotating shaft 13 and the sunshade plate 5 to rotate together, thereby changing the irradiation angle of sunlight on the sunshade plate 5. For specific reference, see Figure 11 , where α in the figure is the incident angle when the sunshade plate 5 does not rotate, and β is the incident angle behind the sunshade plate 5. When the sunshade plate 5 changes color to change its sunshading ability, the incident angle of sunlight when shining on the sunshade plate 5 can also be increased by rotating the sunshade plate 5, thereby improving the light reflection ability of the sunshade plate 5 and avoiding direct sunlight on seeds or seedlings at noon.

[0056] In this way, when the color-changing component drives the sunshade plate 5 to change color and adjust, the hydraulic wheel 15 can also drive the sunshade plate 5 to increase the incident angle and reflection amount of the light irradiating the sunshade plate 5 at the same time. At the same time, the cam 14 is driven by the rotating shaft 13 to adjust the irrigation rate of the irrigation component, so that the adjustment of the color-changing component, the irrigation amount of the irrigation component, and the refraction ability of the sunshade plate 5 change linearly and synchronously. Then, the humidity sensor 12 drives the sliding box 17 to perform non-linear adjustment on the irrigation amount of the irrigation component through the electromagnet 20, further enhancing the coupling between each component and thus reducing the impact of the external environmental temperature on the growth and development of seeds or seedlings.

[0057] Further, a solar panel 8 is fixedly installed on the top surface of the hydraulic tank 2, and a storage battery 24 for storing electric energy is fixedly installed inside the bracket. The storage battery 24 and the humidity sensor 12 form an energized circuit.

[0058] According to the above embodiments, the solar panel 8 generates electricity and cooperates with the storage battery 24 to store the generated electricity, which can supply power to the humidity sensor 12 in the field environment, further expanding the application range of the device.

[0059] Example 1:

[0060] Further, the driving component includes a cylinder 26 fixedly installed on the bottom surface. The output shaft of the cylinder 26 penetrates into the hydraulic tank 2 and is fixedly connected to the bottom surface of the hydraulic plate 22. The storage battery 24 supplies power to the cylinder 26 through a current sensor.

[0061] According to the above embodiments, when the external light intensity increases, the power generation of the solar panel 8 also increases synchronously. When the power generation of the solar panel 8 reaches the preset value, that is, when the current sensor detects that the current in the storage battery 24 reaches the preset value, the cylinder 26 is started to drive the hydraulic plate 22 to move downward, driving the color-changing component and the irrigation component to adjust synchronously. When the light intensity decreases, the decrease in power generation drives the cylinder 26 to reset, completing the reciprocating sliding adjustment of the hydraulic plate 22 up and down.

[0062] Embodiment 2:

[0063] Furthermore, the driving component includes a fixed box 23 fixedly installed on the top surface of the hydraulic tank 2. The bottom end of the fixed box 23 is communicated with the hydraulic tank 2. A liquid or gas material capable of absorbing heat and expanding is provided inside the fixed box 23. A heat absorption plate 21 is fixedly installed on the side wall of the fixed box 23.

[0064] According to the above embodiment, when the external light intensity increases, the temperature of the heat absorption plate 21 rises to reach the sensitive range of the liquid (such as kerosene) or gas (such as helium) material inside the fixed box 23. When the liquid or gas absorbs heat and expands, it can drive the hydraulic plate 22 to move downward. When the external light intensity decreases, when the liquid or gas gradually contracts, it drives the hydraulic plate 22 to move upward, completing the reciprocating sliding adjustment of the hydraulic plate 22.

[0065] Furthermore, a rotatable rotating disk is provided at the bottom end of the base 1.

[0066] According to the above embodiment, by providing a rotatable rotating disk at the bottom end of the base 1, the uniformity of the light intensity received by the seeds or seedlings in the seedling raising box can also be improved by rotating the seedling raising tray 7.

[0067] The standard parts used in this embodiment can be directly purchased from the market. For the non-standard structural components described in the specification and drawings, they can also be directly processed according to the existing common technical knowledge without any doubt. At the same time, the connection methods of each component adopt the mature conventional means in the existing technology, and the machines, parts and equipment all adopt the conventional models in the existing technology. Therefore, no specific description will be made here.

[0068] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
