Description

Technical Field

[0001] This invention relates to the field of planting racks, and more specifically, to an intelligent forage seedling rack. Background Technology

[0002] With the continuous expansion of my country's animal husbandry industry, the demand for forage is also increasing. Currently, people use seedling racks in greenhouses to cultivate forage to ensure the forage supply chain. However, because the forage seedlings grow relatively densely, they cannot photosynthesize evenly, resulting in reduced seedling efficiency. To ensure that the forage seedlings can photosynthesize successfully, it is necessary to install plant growth lights on the seedling racks. However, existing seedling racks equipped with plant growth lights generally have the following problems;

[0003] First, plant grow lights generate a significant amount of heat during continuous operation. Traditional cooling methods rely on natural heat dissipation or forced air cooling, but their efficiency is significantly affected by ambient temperature. Especially in enclosed growing spaces, heat accumulation can easily cause the lamp body temperature to exceed 60°C, shortening the lamp's lifespan and triggering localized heat stress, thus inhibiting the photosynthetic efficiency of the forage grass. Second, to maintain the temperature required for forage grass growth at night, additional electric heating equipment is needed, further increasing energy consumption. Third, existing growing rack ventilation designs often use a single air outlet layout, which cannot adjust the airflow direction according to day and night, thus affecting the forage grass's carbon dioxide requirements during day and night growth.

[0004] Therefore, in order to solve the above problems, an intelligent forage seedling rack was proposed. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the problems existing in the prior art, this invention provides an intelligent forage seedling rack. This solves the problem mentioned in the background art where plant grow lights generate a large amount of heat during continuous operation. Traditional heat dissipation methods rely on natural cooling or forced air cooling, but the efficiency is significantly affected by ambient temperature. Especially in enclosed planting spaces, heat accumulation can easily cause the lamp body temperature to exceed 60°C, not only shortening the lamp's lifespan but also triggering localized heat stress and inhibiting the photosynthetic efficiency of forage. Furthermore, to maintain the temperature required for forage growth at night, additional electric heating equipment is needed, further exacerbating energy consumption. Secondly, existing planting rack ventilation designs mostly use a single air outlet layout, which cannot adjust the airflow direction according to day and night, thus affecting the carbon dioxide requirements of forage during day and night growth.

[0013] The present invention is further configured such that the first heat-conducting shell, the second heat-conducting shell, and the heat-conducting plate are all made of aluminum metal, and multiple limiting blocks are fixedly installed along the upper edge of the inner cavity of the receiving groove. The limiting blocks are located above the heat-conducting plate. A fixing strip is fixedly installed at the upper end of the second heat-conducting shell, and multiple counterweights are fixedly installed at the upper end of the fixing strip, and the counterweights are equidistantly distributed among them.

[0014] The present invention is further configured such that the switching component includes an air inlet pipe disposed on the left side of the housing, the air inlet pipe being disposed in the middle of the housing and connected to the housing, a first exhaust pipe being connected to the upper end of the housing, a first air blowing channel being fixedly installed on the upper end of the planting rack body, the upper end of the first exhaust pipe being connected to the air inlet end of the first air blowing channel, a second exhaust pipe being connected to the lower end of the housing, a second air blowing channel being connected to the lower end of the second exhaust pipe, the second air blowing channel being fixedly installed below the planting rack body, and both the first air blowing channel and the second air blowing channel having multiple air outlets.

[0017] (III) Beneficial Effects

[0018] Compared with existing technologies, this invention provides an intelligent forage seedling rack with the following beneficial effects: During the day, the invention conducts heat from the arc-shaped heat dissipation fins through a first heat-conducting shell that is in contact with the arc-shaped heat dissipation fins, in conjunction with a second heat-conducting shell. Furthermore, the phase change material within the cavities of the first and second heat-conducting shells absorbs and stores heat, further improving the heat conduction effect of the arc-shaped heat dissipation fins. This extends the lifespan of the plant growth lamp, reduces localized heat stress caused by heat accumulation during the day, ensures normal photosynthesis in the forage, and achieves synergistic improvement in both the performance of the plant growth lamp and the forage growth environment.

[0019] Furthermore, at night, the second heat-conducting shell inside the first heat-conducting shell can slide out from the receiving groove, thereby forming a heat-generating area on both sides of the plant growth lamp body in conjunction with the first heat-conducting shell and the second heat-conducting shell. At night, the phase change material inside the first heat-conducting shell and the second heat-conducting shell will solidify from a liquid state to a solid state, thereby releasing the stored heat. Combined with the downward airflow from above at night, the airflow carries heat to form a hot airflow that blows towards the pasture canopy, thereby reducing the need for electric heating at night and further reducing the energy consumption for pasture planting at night.

[0020] The first gear can be rotated during the upward movement of the fixed frame, causing the third rack to drive the rubber plug below to insert into the second exhaust pipe, thereby sealing the second exhaust pipe. This ensures that the airflow entering the shell through the intake pipe can only flow into the first exhaust pipe, thus switching the airflow direction and allowing the airflow to be discharged from the first air blowing channel above the main body of the planting frame. This allows the airflow to wash over the canopy of the pasture from top to bottom at night, quickly expelling the carbon dioxide waste gas released by the pasture's respiration at night through the bottom exhaust port, preventing the accumulation of carbon dioxide from inhibiting the respiration of the pasture. Furthermore, the downward airflow can cooperate with the phase change material in the first and second heat-conducting shells to release heat, thereby allowing the airflow to carry heat and form a hot airflow that blows towards the pasture canopy, thus promoting the stable respiration of the pasture at night.

[0021] During the resetting process of the fixing frame, the third rack can drive the rubber plug above to insert into the first exhaust pipe, thereby blocking the first exhaust pipe and allowing airflow to flow into the second exhaust pipe and be discharged from the second air blowing channel. This ensures that fresh air diffuses upward from the bottom of the planting rack, forming an upward airflow. This ensures that the canopy of pasture can come into contact with sufficient carbon dioxide to achieve photosynthesis. In addition, the upward airflow will carry away the hot air at the bottom generated by the heat dissipation of the plant growth lamp body, preventing heat from accumulating in the lower layer and causing heat stress, and further improving the heat dissipation effect of the plant growth lamp body.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0035] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the directions shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0036] Example 1, referring to Figures 1 to 7 This is the first embodiment of the present invention. This embodiment provides an intelligent forage seedling rack, which can improve the heat dissipation effect of plant growth lamps, reduce the impact of plant growth lamp heat on forage growth, and can utilize the heat of plant growth lamps to generate warm airflow for forage at night, ensuring the growth of forage at night. It includes a lighting auxiliary mechanism 100, which includes a planting rack body 101 and a plant growth lamp body 103 disposed in the middle of the planting rack body 101. A placement rack 102 is disposed below the plant growth lamp body 103. A heat absorption component for absorbing the heat of the lighting lamp is disposed above the plant growth lamp body 103. An extension component for unfolding the heat absorption component is disposed at the left end of the plant growth lamp body 103. An airflow switching mechanism 200 is disposed on the left side of the plant growth lamp body 103. The airflow switching mechanism 200 includes a housing 201 disposed on the left side of the plant growth lamp body 103 and a switching component disposed in the inner cavity of the housing 201 for switching the upper and lower air ducts in a linkage manner.

[0037] In this embodiment, the placement frame 102 is fixedly connected to the planting frame body 101 by welding. In the initial state, the heat-absorbing component is in contact with the heat dissipation part on the plant grow lamp body 103. Through the thermal conductivity of the heat-absorbing component, the heat-absorbing component conducts and absorbs the heat generated by the plant grow lamp body 103 during the day, thereby improving the heat dissipation effect of the plant grow lamp body 103 and avoiding the accumulation of heat during the day that could cause local heat stress and inhibit the photosynthetic efficiency of the pasture. This achieves synergistic improvement of the performance of the plant grow lamp body 103 and the pasture growth environment. At the same time, the phase change material in the heat-absorbing component can accumulate heat and store it above the plant grow lamp body 103, reducing the impact of daytime heat on the pasture. When the temperature drops at night, the extension component is controlled to rotate and unfold the heat-absorbing component, thereby forming heat-releasing areas on both sides of the plant grow lamp body 103. At night, the phase change material solidifies from liquid to solid, releasing the stored heat. Combined with the downward airflow at night, the airflow carries heat to form a hot airflow that blows towards the pasture canopy, thereby reducing the heat loss at night. The need for electric heating further reduces the energy consumption of forage planting. At the same time, during the nighttime deployment of the heat-absorbing components, the switching components inside the housing 201 will be activated, causing the switching components to close the air intake channel below the planting rack body 101 and open the air intake channel above the planting rack body 101. This allows the nighttime airflow to wash over the forage canopy from top to bottom, quickly expelling the carbon dioxide waste gas released by the forage's respiration through the bottom exhaust vent, preventing carbon dioxide accumulation from inhibiting the forage's respiration. Conversely, when the heat-absorbing components reset during the day to absorb heat, the air intake channel below the planting rack body 101 will be opened again, while the air intake channel above the planting rack body 101 will be closed. This ensures that fresh air (containing 0.04% carbon dioxide) diffuses upward from the bottom of the planting rack, forming an upward airflow. This ensures that the forage canopy can come into contact with sufficient carbon dioxide to achieve photosynthesis. Furthermore, the upward airflow will carry away the hot air generated by the heat dissipation of the plant growth lamp body 103, preventing heat accumulation at the lower level and causing heat stress, further improving the heat dissipation effect of the plant growth lamp body 103.

[0038] Specifically, the heat-absorbing component includes an arc-shaped heat dissipation fin 111 disposed above the plant grow lamp body 103. The lower end of the arc-shaped heat dissipation fin 111 is detachably connected to the upper end of the plant grow lamp body 103. Fixing rings 104 are fixedly installed at both ends of the plant grow lamp body 103. Arc-shaped grooves 106 are formed on both sides of the fixing rings 104. A first heat-conducting shell 107 is disposed above the arc-shaped heat dissipation fin 111. Sliding rods 108 are welded to both the left and right ends of the first heat-conducting shell 107. Limiting rods 109 are fixedly installed at both ends of the plant grow lamp body 103. The lower end of the sliding rods 108 is welded with… The plant growth lamp body 103 has a gear ring 110. Both ends of the plant growth lamp body 103 are fixedly connected to the planting frame body 101 via connecting rods 105. The size of the sliding rod 108 is adapted to the size of the arc groove 106, and the sliding rod 108 is movably connected to the arc groove 106. The gear ring 110 is sleeved on the outside of the limiting rod 109, and the gear ring 110 is slidably connected to the outer wall of the limiting rod 109. The inner cavity of the first heat-conducting shell 107 is provided with a receiving groove 116, and the inner cavity of the receiving groove 116 is provided with a second heat-conducting shell 118. Both the first heat-conducting shell 107 and the second heat-conducting shell 118 are provided with cavities 115.

[0039] In this embodiment, during operation, the heat generated by the LED beads in the plant growth lamp body 103 is first conducted and dissipated through the arc-shaped heat dissipation fins 111 during the day. Then, the heat of the arc-shaped heat dissipation fins 111 is conducted through the first heat-conducting shell 107 and the second heat-conducting shell 118, which are attached to the arc-shaped heat dissipation fins 111. Furthermore, the heat is absorbed and stored by the phase change material set in the cavity 115 of the first heat-conducting shell 107 and the second heat-conducting shell 118, which further improves the heat conduction effect of the arc-shaped heat dissipation fins 111. This improves the service life of the plant growth lamp body 103, reduces the local thermal stress caused by heat accumulation during the day, ensures the normal photosynthesis of pasture, and achieves the synergistic improvement of the performance of the plant growth lamp body 103 and the pasture growth environment.

[0040] It is worth noting that the lower part of the first heat-conducting shell 107 is arc-shaped, and the lower end of the first heat-conducting shell 107 is in contact with the upper surface of the arc-shaped heat dissipation fin 111, thereby ensuring the heat conduction effect of the first heat-conducting shell 107 on the arc-shaped heat dissipation fin 111. In addition, the arc-shaped groove 106 on the fixing ring 104 can limit the position of the first heat-conducting shell 107 during rotation, thereby ensuring the stability of the first heat-conducting shell 107 during rotation. At the same time, the setting of the limiting rod 109 can ensure that the gear ring 110 is stably driven to rotate outside the limiting rod 109.

[0041] Furthermore, the extension assembly includes two electric telescopic rods 114 positioned above the main body 101 of the planting frame. The lower ends of the electric telescopic rods 114 are connected to the upper ends of the main body 101 of the planting frame by bolts. A fixing frame 113 is installed at the output end of the electric telescopic rods 114. A first rack 112 is fixedly installed on the lower end of the fixing frame 113 near the gear ring 110. A heat-conducting plate 119 is fixedly installed on the lower end of the second heat-conducting shell 118. Two first racks 112 are symmetrically arranged and mesh with the gear ring 110. The size of the receiving groove 116 is larger than that of the second heat-conducting shell 118. The cavity 115 is filled with modified paraffin wax. Multiple balls 120 are rolled on both ends of the heat-conducting plate 119 and are evenly distributed. The smooth surface of the balls 120 is in contact with the inner wall of the receiving groove 116. The first heat-conducting shell 107, the second heat-conducting shell 118 and the heat-conducting plate 119 are all made of aluminum. Multiple limiting blocks 117 are fixedly installed on the upper edge of the inner cavity of the receiving groove 116. The limiting blocks 117 are located above the heat-conducting plate 119. A fixing strip 121 is fixedly installed on the upper end of the second heat-conducting shell 118. Multiple counterweights 122 are fixedly installed on the upper end of the fixing strip 121 and are evenly distributed.

[0042] In this embodiment, at night, the electric telescopic rod 114 is extended, causing the fixed frame 113 to move upward. The fixed frame 113 then causes the first rack 112 to move upward, which in turn causes the gear ring 110 to rotate. The gear ring 110 rotates along the surface of the limiting rod 109, which in turn causes the sliding rod 108 connected to the gear ring 110 to rotate as well. This causes the sliding rod 108 to rotate the connected first heat-conducting shell 107 downward, thereby causing the two first heat-conducting shells 107 to rotate to both sides of the plant growth lamp body 103, with the first heat-conducting shells 107 tilting downward. Meanwhile, since the first heat-conducting shell 107 is in a downward tilted state, the second heat-conducting shell 118 inside the first heat-conducting shell 107 will slide out from the receiving groove 116, thereby forming a heat-releasing area on both sides of the plant growth lamp body 103 in conjunction with the first heat-conducting shell 107 and the second heat-conducting shell 118. At night, the phase change material inside the first heat-conducting shell 107 and the second heat-conducting shell 118 will solidify from liquid to solid, thereby releasing the stored heat. Combined with the downward airflow from above at night, the airflow carries heat to form a hot airflow that blows towards the pasture canopy, thereby reducing the need for electric heating at night and further reducing the energy consumption for planting pasture at night.

[0043] It is worth noting that by using the limiting block 117 and the heat-conducting plate 119 together, the sliding position of the second heat-conducting shell 118 can be limited, thereby preventing the second heat-conducting shell 118 from separating from the first heat-conducting shell 107. Furthermore, both the first heat-conducting shell 107 and the second heat-conducting shell 118 are provided with sealing caps on their left sides, which facilitates the replacement or addition of phase change materials.

[0044] During use, during the daytime, the heat generated by the LED beads in the plant grow light body 103 is first conducted away through the arc-shaped heat dissipation fins 111. Then, the heat is conducted away through the first heat-conducting shell 107 and the second heat-conducting shell 118, which are attached to the arc-shaped heat dissipation fins 111. Furthermore, the phase change material within the cavity 115 of the first and second heat-conducting shells 107 and 118 absorbs and stores the heat, further improving the heat conduction effect of the arc-shaped heat dissipation fins 111. This extends the lifespan of the plant grow light body 103 and reduces the risk of heat buildup during the day. Localized heat stress inhibits the photosynthetic efficiency of pasture, achieving synergistic improvement in the performance of the plant growth lamp body 103 and the pasture growth environment. At night, the time relay transmits a signal to the PLC controller, which controls the electric telescopic rod 114 to extend. The electric telescopic rod 114 drives the fixed frame 113 to move upward, which in turn drives the first rack 112 to move upward. The first rack 112 drives the gear ring 110 to rotate, and the gear ring 110 rotates along the surface of the limit rod 109, thereby driving the sliding rod 108 connected to the gear ring 110 to rotate as well. The first heat-conducting shell 107 rotates downwards, causing both first heat-conducting shells 107 to rotate to both sides of the plant growth lamp body 103. The first heat-conducting shells 107 are tilted downwards. Simultaneously, because the first heat-conducting shells 107 are tilted downwards, the second heat-conducting shells 118 inside the first heat-conducting shells 107 slide out from the receiving groove 116. This causes the first heat-conducting shells 107 and 118 to form heat-dissipating areas on both sides of the plant growth lamp body 103. At night, the phase change material inside the first heat-conducting shells 107 and 118 solidifies from a liquid state to a solid state, releasing the stored heat. At night, the airflow from above blows down, carrying heat to form a hot airflow that blows towards the pasture canopy, thereby reducing the need for electric heating at night and further reducing the energy consumption for pasture planting at night. During the day, the PLC controller controls the electric telescopic rod 114 to retract and reset. The electric telescopic rod 114 drives the fixed frame 113 to move downward, which in turn drives the first heat-conducting shell 107 to rotate upward. When the first heat-conducting shell 107 rotates to its position, the second heat-conducting shell 118 slides down and resets along the inner wall of the receiving groove 116 by the weight of the fixing strip 121 and the counterweight 122 until the heat-conducting plate 119 is in contact with the inner wall of the first heat-conducting shell 107.

[0045] Example 2, refer to Figures 1 to 10 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an intelligent forage seedling rack, which solves the problem that the airflow direction cannot be adjusted according to day and night, thus affecting the forage's demand for carbon dioxide. The switching component includes an air inlet pipe 206 located on the left side of the housing 201. The air inlet pipe 206 is located in the middle of the housing 201 and is connected to the housing 201. The upper end of the housing 201 is connected to a first exhaust pipe 202. The upper end of the planting rack body 101 is fixedly installed with a first air blowing channel 203. The upper end of the first exhaust pipe 202 is connected to the air inlet end of the first air blowing channel 203. The lower end of the housing 201 is connected to a second exhaust pipe 204. The lower end of the second exhaust pipe 204 is connected to a second air blowing channel 205. The second air blowing channel 205 is fixedly installed below the planting rack body 101. Both the first air blowing channel 203 and the second air blowing channel 205 have multiple air outlets.

[0046] In this embodiment, the first air blowing channel 203 and the second air blowing channel 205 work together to form airflow channels at both the top and bottom of the planting rack body 101. This avoids the problem that a single air outlet layout cannot meet the ventilation needs of the forage under different conditions during the day and night, thus affecting the production of the forage. Furthermore, the housing 201 is designed to control the air intake of the first exhaust pipe 202 and the second exhaust pipe 204, thereby achieving the switching of airflow direction during the day and night, further ensuring the carbon dioxide requirements of the forage during its growth process during the day and night.

[0047] Specifically, a support plate 207 is welded to the lower part of the planting frame body 101 near the shell 201. A rotating rod 208 is provided on the side of the support plate 207 near the shell 201. A first gear 209 is fixedly installed in the middle of the rotating rod 208. A second rack 210 is fixedly installed on the lower end of the fixing frame 113 near the shell 201. A second gear 211 is fixedly installed on the end of the rotating rod 208 away from the support plate 207. A third rack 213 is provided on the rear side of the second gear 211. Rubber plugs 214 are fixedly installed at both the upper and lower ends of the third rack 213. The rotating rod 208 is located near the support plate 201. One end of 7 is rotatably connected to the support plate 207 via a bearing. The side of the rotating rod 208 near the intake pipe 206 is rotatably connected to the housing 201 via a sealed bearing. The second rack 210 meshes with the first gear 209. A limit frame 212 is fixedly installed at the upper end of the inner cavity of the housing 201. The limit frame 212 is movably connected to the third rack 213. The third rack 213 meshes with the second gear 211. The size of the rubber plug 214 is adapted to the inner cavity size of the first exhaust pipe 202 and the second exhaust pipe 204. The rubber plug 214 is movably connected to the inner cavity of the first exhaust pipe 202 and the second exhaust pipe 204, respectively.

[0048] In this embodiment, at night, as the electric telescopic rod 114 extends, it drives the fixed frame 113 to move upward. The fixed frame 113 also drives the second rack 210 to move upward. During the upward movement of the second rack 210, it drives the first gear 209 to rotate, which in turn drives the rotating rod 208 to rotate. This causes the second gear 211 on the rotating rod 208 to rotate, which in turn drives the third rack 213 to move downward. The third rack 213 then drives the rubber plug 214 below to insert into the second exhaust pipe 204, thereby venting the second exhaust pipe. By sealing the air duct 204, the airflow entering the housing 201 through the air inlet 206 can only flow into the first exhaust pipe 202, thereby switching the airflow direction and causing the airflow to exit from the first air blowing channel 203 above the planting rack body 101. This allows the airflow to wash over the canopy of the pasture from top to bottom at night, quickly expelling the carbon dioxide waste gas released by the pasture's respiration at night through the bottom exhaust port, preventing carbon dioxide accumulation from inhibiting the pasture's respiration. Furthermore, the downward-blowing airflow can interact with the first heat-conducting shell 107 and the second heat-conducting shell 1. The phase change material within 18 releases heat, causing the airflow to carry heat and form a hot airflow that blows towards the pasture canopy, thus promoting stable respiration of the pasture at night. During the day, the PLC controller controls the electric telescopic rod 114 to retract and reset. The electric telescopic rod 114 drives the fixed frame 113 to move downward, which in turn drives the first heat-conducting shell 107 to rotate upward. When the first heat-conducting shell 107 has rotated to its position, the fixed frame 113 stops moving. At the same time, the second rack 210 on the fixed frame 113 moves downward, which in turn drives the third rack 213 to move upward, causing the third rack... Strip 213 drives the rubber plug 214 above to be inserted into the first exhaust pipe 202, thereby blocking the first exhaust pipe 202 and allowing airflow to flow into the second exhaust pipe 204 and be discharged from the second air blowing channel 205. This ensures that fresh air diffuses upward from the bottom of the planting rack, forming an upward airflow. This ensures that the grass canopy can come into contact with sufficient carbon dioxide to achieve photosynthesis. In addition, the upward airflow will carry away the hot air at the bottom generated by the heat dissipation of the plant growth lamp body 103, preventing heat from accumulating in the lower layer and causing heat stress, and further improving the heat dissipation effect of the plant growth lamp body 103.

[0049] It is worth noting that since the size of the rubber plug 214 is adapted to the inner cavity size of the first exhaust pipe 202 and the second exhaust pipe 204, the sealing effect of the rubber plug 214 on the first exhaust pipe 202 and the second exhaust pipe 204 is guaranteed. Furthermore, the setting of the limiting frame 212 ensures the stability of the upward movement of the third rack 213, thereby facilitating the sealing of the first exhaust pipe 202 or the second exhaust pipe 204. The setting of the support plate 207 ensures the stability of the rotating rod 208.

[0050] The rest of the structure is the same as in Example 1.

[0051] During use, at night, the electric telescopic rod 114 extends, causing the fixed frame 113 to move upward. The fixed frame 113 also causes the second rack 210 to move upward. As the second rack 210 moves upward, it in turn drives the first gear 209 to rotate, which in turn drives the rotating rod 208 to rotate. This causes the second gear 211 on the rotating rod 208 to rotate, which in turn drives the third rack 213 to move downward. The third rack 213 then drives the rubber plug 214 below to insert into the second exhaust pipe 204, thereby venting the second exhaust. Pipe 204 is sealed to ensure that the airflow entering the housing 201 through the air inlet pipe 206 can only flow into the first exhaust pipe 202, thereby switching the airflow direction and causing the airflow to be discharged from the first blowing channel 203 above the planting rack body 101. This allows the airflow to wash over the canopy of the pasture from top to bottom at night, quickly expelling the carbon dioxide waste gas released by the pasture's respiration at night through the bottom exhaust port, preventing carbon dioxide accumulation from inhibiting the pasture's respiration. Furthermore, the downward-blowing airflow can interact with the first heat-conducting shell 107 and the second heat-conducting shell 11. The phase change material inside the 8 unit releases heat, causing the airflow to carry heat and form a hot airflow that blows towards the pasture canopy, thus promoting stable respiration of the pasture at night. During the day, the PLC controller controls the electric telescopic rod 114 to retract and reset. The electric telescopic rod 114 drives the fixed frame 113 to move downward, which in turn drives the first heat-conducting shell 107 to rotate upward. When the first heat-conducting shell 107 has rotated to its position, the fixed frame 113 stops moving. At the same time, the second rack 210 on the fixed frame 113 moves downward, which in turn drives the third rack 213 to move upward, causing the third rack 210 to rotate downward. Strip 213 drives the rubber plug 214 above to be inserted into the first exhaust pipe 202, thereby blocking the first exhaust pipe 202 and allowing airflow to flow into the second exhaust pipe 204 and be discharged from the second air blowing channel 205. This ensures that fresh air diffuses upward from the bottom of the planting rack, forming an upward airflow. This ensures that the grass canopy can come into contact with sufficient carbon dioxide to achieve photosynthesis. In addition, the upward airflow will carry away the hot air at the bottom generated by the heat dissipation of the plant growth lamp body 103, preventing heat from accumulating in the lower layer and causing heat stress, and further improving the heat dissipation effect of the plant growth lamp body 103.
