Description

Technical Field

[0001] This utility model relates to the technical field of tobacco seedling raising equipment, and in particular to an adaptive light-regulating tobacco seedling raising shed. Background Technology

[0002] In tobacco cultivation, the seedling stage is crucial, as it directly affects the quality and yield of tobacco leaves. Adaptive light-regulating tobacco seedling sheds, as an advanced seedling facility, are designed to provide suitable light regulation for tobacco seedling growth.

[0003] However, when encountering extreme weather such as blizzards, the heavy snow covering the seedling sheds causes the temperature inside to drop significantly, severely affecting the normal growth and development of tobacco seedlings. This results in slow growth and even frost damage, greatly reducing the survival rate and quality of the seedlings. Tobacco is a light-loving crop, and the snow blocks sunlight from penetrating, leading to insufficient light intensity inside the sheds, which further affects the growth of the seedlings.

[0004] To address these shortcomings, we proposed an adaptive light-regulating tobacco seedling greenhouse. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an adaptive light-regulating tobacco seedling shed.

[0006] The objective of this utility model is achieved through the following technical solution: an adaptive light-regulating tobacco seedling greenhouse, comprising a base, an upper surface of which is fitted with a surface glass, and an electric heating wire is attached to the lower surface of the surface glass. A lower glass is installed on the upper surface of the base and on the inner side of the surface glass. Adjacent surface glass and adjacent lower glass are bonded with frames by adhesive. An air outlet pipe is installed through the side surface of the surface glass, and an air inlet pipe is installed through the side surface of the surface glass. The air inlet pipe is connected to a heating box, and a resistance heating rod is installed inside the heating box. A fan is connected to the upper surface of the heating box, and a light sensor is installed on the inner side of the lower glass.

[0007] Furthermore, a grid frame is installed on the inner side of the lower glass, and a supplementary light is bolted to the lower surface of the grid frame. A cleaning frame is installed on the lower surface of the grid frame and on the outer side of the supplementary light. The cleaning frame is slidably connected to a rotating ring, and the outer side of the rotating ring is provided with teeth. The teeth are meshed with a gear, which is installed at the output end of a servo motor. A cleaning brush is installed on the upper surface of the rotating ring, and an air nozzle is opened on the upper surface of the rotating ring. An air pump is connected to the rotating ring through a duct. A dust sensor is installed on the inner side of the cleaning frame.

[0008] Furthermore, the outer glass is made of explosion-proof quartz glass, and the lower glass is made of electrochromic glass.

[0009] Furthermore, guide vanes are interleaved and bonded between the outer and lower glass layers. Furthermore, a dust filter is installed at the air inlet of the fan.

[0010] Furthermore, an integrated controller is glued to the outer surface of the surface glass. This invention has the following advantages:

[0011] (1) In this utility model, the light sensor is used to monitor the light intensity in the greenhouse in real time. When the snow covers the surface of the greenhouse, resulting in insufficient light, the fan and resistance heating rod can be started. The wind passes through the heating box and the wind heats up. The hot air enters the air gap between the surface glass and the lower glass. The heat is dissipated outward through the surface glass and the lower glass. On the one hand, the temperature of the greenhouse is maintained to prevent the tobacco seedlings from being frozen. On the other hand, the snow is indirectly heated to promote the melting of the snow and prevent the snow from blocking the sunlight and preventing the tobacco seedlings from being illuminated. Secondly, the electric heating wire is set to directly heat the contact surface of the snow and shorten the snow melting time.

[0012] (2) In this utility model, a dust sensor is used to monitor the dust concentration on the surface of the supplemental light in real time. When the dust on the surface of the supplemental light exceeds the threshold, the servo motor is started to drive the rotating ring, which drives the cleaning brush to wipe the lower surface of the supplemental light. At the same time, the air pump is started to blow the supplemental light through the air nozzle to ensure the cleanliness of the supplemental light surface, avoid the supplemental light from being blocked by dust, which would lead to a decrease in light intensity and affect the photosynthesis of tobacco seedlings, provide sufficient light for tobacco seedlings, and promote their uniform growth.

[0026] like Figure 1-6 As shown, the adaptive light-regulating tobacco seedling greenhouse includes a base 1. A top glass 2 is installed on the upper surface of the base 1, and an electric heating wire is attached to the lower surface of the top glass 2. A lower glass 3 is installed on the upper surface of the base 1 and on the inner side of the top glass 2. Frames 4 are glued to adjacent top glass 2 and adjacent lower glass 3. An air outlet pipe is installed through the side surface of the top glass, and an air inlet pipe is installed through the side surface of the top glass. The air inlet pipe is connected to a heating box 6. A resistance heating rod 7 is installed inside the heating box 6. A fan 8 is connected to the upper surface of the heating box 6. A light sensor is installed on the inner side of the lower glass 3.

[0027] In one embodiment, the light sensor is used to monitor the light intensity inside the greenhouse in real time. When snow covers the greenhouse surface, resulting in insufficient light, the fan 8 and resistance heating rod 7 can be activated. The air passes through the heating box 6, and the air temperature rises. The hot air enters the air gap between the outer glass 2 and the lower glass 3, and the heat is dissipated outward through the outer glass 2 and the lower glass 3. On the one hand, the temperature of the greenhouse is maintained to prevent the tobacco seedlings from being damaged by frost. On the other hand, the snow is indirectly heated to promote snow melting and prevent the snow from blocking sunlight and preventing the tobacco seedlings from being exposed to light. Secondly, the setting of electric heating wire directly heats the contact surface of the snow, shortening the snow melting time.

[0028] Specifically, a grid frame 10 is installed on the inner side of the lower glass 3. A supplementary light 11 is bolted to the lower surface of the grid frame 10. A cleaning rack 12 is installed on the lower surface of the grid frame 10 and on the outer side of the supplementary light 11. The cleaning rack 12 is slidably connected to the rotating ring 13. The outer side of the rotating ring 13 is provided with teeth 14, which mesh with gears 15. The gears 15 are installed at the output end of the servo motor 16. A cleaning brush 19 is installed on the upper surface of the rotating ring 13. An air nozzle 20 is opened on the upper surface of the rotating ring 13. An air pump 17 is connected to the rotating ring 13 through an air duct 18. A dust sensor 21 is installed on the inner side of the cleaning rack 12.

[0029] In one embodiment, a dust sensor 21 is used to monitor the dust concentration on the surface of the supplemental light 11 in real time. When the dust on the surface of the supplemental light 11 exceeds a threshold, a servo motor 16 is activated to drive a rotating ring 13, which in turn drives a cleaning brush 19 to wipe the lower surface of the supplemental light 11. At the same time, an air pump 17 is activated to blow the supplemental light 11 through an air nozzle 20, ensuring the cleanliness of the surface of the supplemental light 11 and preventing the light intensity from being reduced due to dust blocking the light, which would affect the photosynthesis of tobacco seedlings. This provides sufficient light for the tobacco seedlings and promotes their uniform growth.

[0030] Specifically, the outer glass 2 is made of explosion-proof quartz glass, and the lower glass 3 is made of electrochromic glass. In one embodiment, the explosion-proof quartz glass has excellent light transmittance and good thermal conductivity, which can maximize the utilization of natural light. At the same time, the hot air in the air gap can heat the snow through the outer glass 2, promoting snow melting. The lower glass 3 can adjust the light transmittance through voltage. When there is insufficient light due to storms, the light transmittance can be increased to enhance natural light. In strong light, the light transmittance can be reduced to avoid scorching of smoke seedlings and reduce the energy consumption of supplemental lighting.

[0031] Specifically, a baffle plate 5 is interleaved and bonded between the surface glass 2 and the lower glass 3.

[0032] In one embodiment, the air deflector 5 is used to create an airflow channel in the air gap between the surface glass 2 and the lower glass 3, ensuring that air can flow through the air gap completely.

[0033] Specifically, the air inlet of the fan 8 is equipped with a dust filter 9.

[0034] In one embodiment, the dust filter 9 can filter dust from the air, prevent dust accumulation on the heating element from causing malfunctions, and extend the equipment's lifespan.

[0035] Specifically, the outer surface of the surface glass 2 is bonded with an integrated controller 22 by adhesive.

[0036] In one embodiment, the integrated controller 22 can access sensor data such as temperature, light, and dust, support remote APP monitoring, and can preset multiple scene modes.

[0037] The working process of this utility model is as follows: Its light sensor is used to monitor the light intensity inside the greenhouse in real time. When snow covers the greenhouse surface, causing insufficient light, the fan 8 and resistance heating rod 7 are activated. The airflow passes through the heating box 6, raising the temperature. The hot air enters the air gap between the outer glass 2 and the lower glass 3, and the heat is dissipated outward through the outer glass 2 and the lower glass 3. This maintains the greenhouse temperature on one hand, preventing the tobacco seedlings from freezing, and on the other hand, indirectly heats the snow, promoting its melting and preventing it from blocking sunlight and hindering the tobacco seedlings from receiving light. Secondly, the electric heating wire is designed... The device directly heats the snow-covered contact surface, shortening the snow melting time. A dust sensor 21 monitors the dust concentration on the surface of the supplemental light 11 in real time. When the dust concentration on the surface of the supplemental light 11 exceeds a threshold, a servo motor 16 is activated to drive a rotating ring 13, which in turn drives a cleaning brush 19 to wipe the lower surface of the supplemental light 11. Simultaneously, an air pump 17 is activated to blow air through an air nozzle 20 onto the supplemental light 11, ensuring the cleanliness of the surface and preventing the light intensity from being reduced due to dust blocking the light, thus affecting the photosynthesis of tobacco seedlings and providing sufficient light for the seedlings to promote their uniform growth.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
