Description

Technical Field

[0001] This utility model relates to the field of Torreya grandis seedling technology, and in particular to a constant temperature and humidity Torreya grandis seedling box.

[0002] Background Technology

[0003] The Chinese patent announcement number CN217850390U discloses a seedling cultivation device for Torreya grandis. Its core innovation lies in the closed-loop irrigation system constructed by a water pump, distribution pipe and sprinkler head. Compared with traditional manual spraying, it can achieve uniform water supply in the cultivation pot and effectively avoid the risk of local water accumulation or drought.

[0004] In practical applications, it has been found that under constant temperature conditions, the photosynthesis, respiration, and enzyme activity of Torreya grandis seedlings remain stable, promoting dry matter accumulation and healthy stem and leaf growth, and avoiding metabolic disorders caused by sudden temperature changes. However, existing devices rely entirely on ambient temperature and humidity, lacking active regulation capabilities, especially in winter when the ambient temperature is too low, thus affecting the growth of Torreya grandis. To address these shortcomings, we propose a constant temperature and humidity seedling box for Torreya grandis used in winter. Utility Model Content

[0035] Please see Figure 1-9 This utility model provides a technical solution: a constant temperature and humidity seedling box for Torreya grandis, comprising: an insulated box 10, an insulated structure, a spray structure, and a supplemental lighting structure.

[0037] The insulation structure consists of a water tank 20 located on the back of the insulation box 10, an electric heating rod 21 fixedly installed on the inner wall of the water tank 20, a water supply assembly located on the outer surface of the water tank 20, and a pipe assembly located inside the insulation box 10. The electric heating rod 21 can heat the water in the water tank 20. Water temperature sensors are installed in both the water tank 20 and the insulation box 10. A humidity sensor is also installed inside the insulation box 10. When the water temperature reaches the design value, the electric heating rod 21 is automatically turned off. A temperature and humidity monitor 80 is fixedly installed on the right side of the insulation box 10. The temperature and humidity monitor 80 can monitor and control the temperature and humidity inside the insulation box 10, as well as control the water temperature in the water tank 20.

[0038] The piping assembly includes a first water supply copper pipe 30 fixedly installed on the left side wall inside the insulation box 10, a second water supply copper pipe 31 fixedly installed on the rear wall inside the insulation box 10, and a third water supply copper pipe 32 fixedly installed on the right side wall inside the insulation box 10. One end of the first water supply copper pipe 30 is connected to one end of the second water supply copper pipe 31. The water supply assembly includes an inlet pipe 40 and a drain pipe 41 fixedly installed on the front of the water storage tank 20. A water pump 42 is fixedly installed on one end of the inlet pipe 40. The end of the second water supply copper pipe 31 away from the first water supply copper pipe 30 is fixedly connected to the drain end of the water pump 42. One end of the third water supply copper pipe 32 is connected to one end of the drain pipe 41. One end of both the inlet pipe 40 and the drain pipe 41 extends into the interior of the water storage tank 20. Driving the water pump 42 can pump water from the water storage tank 20 into the second water supply copper pipe 31.

[0039] The supplemental lighting structure includes a plant supplemental lighting component fixedly installed on the top wall inside the insulated box 10, and a heat dissipation component set on the surface of the plant supplemental lighting component. The plant supplemental lighting component includes multiple lamp holders 60 fixedly installed at equal intervals on the top wall inside the insulated box 10, a lamp cover 61 threadedly connected to the inner wall of the lamp holder 60, and a plant supplemental light 62 fixedly installed on the inner wall of the lamp cover 61. The lamp cover 61 is made of copper. When the plant supplemental light 62 is driven, the plant supplemental light 62 can be used to supplement the light of the Torreya grandis.

[0040] The heat dissipation assembly consists of a spiral heat dissipation copper pipe 70 fixedly installed on the surface of the lampshade 61, and a connecting pipe 71 for connecting two adjacent spiral heat dissipation copper pipes 70 to each other. All the spiral heat dissipation copper pipes 70 on the lampshade 61 form a unidirectional series water path through the connecting pipe 71. The end of the first water supply copper pipe 30 away from the second water supply copper pipe 31 is fixedly connected to the left end of the spiral heat dissipation copper pipe 70 on the lampshade 61 on the left side of the heat preservation box 10. The end of the third water supply copper pipe 32 away from the drain pipe 41 is fixedly connected to the left end of the spiral heat dissipation copper pipe 70 on the lampshade 61 on the right side of the heat preservation box 10. When the water pump 42 is driven, the water pump 42 can draw water from the water storage tank 20 into the second water supply copper pipe 31. The water entering the second water supply copper pipe 31 will flow along the first water supply copper pipe 30, the spiral heat dissipation copper pipe 70, the connecting pipe 71 and the third water supply copper pipe 32 respectively, and then be discharged into the water storage tank 20 along the drain pipe 41.

[0041] The electric heating rod 21 can raise the water temperature in the water storage tank 20 to the temperature required for Torreya grandis cultivation. After the water passes through the second water supply copper pipe 31, the first water supply copper pipe 30, the connecting pipe 71, and the third water supply copper pipe 32, the heat radiation from these pipes can control the temperature inside the insulation box 10, ensuring a constant temperature and reducing the problem of slow growth of Torreya grandis caused by low winter temperatures. In addition, the plant grow light 62 generates heat when it is working. When the water passes through the lamp cover 61, it carries away the heat from the lamp cover 61. The spiral heat dissipation copper pipe 70 absorbs the residual heat from the lamp cover 61, reducing the surface temperature of the lamp cover 61 while recovering heat energy, thereby reducing the energy consumption of the electric heating rod 21.

[0042] The spray structure includes a rectangular spray pipe 50, a spray head 51 fixedly installed on the lower surface of the rectangular spray pipe 50, a connecting pipe 52 fixedly installed on the upper end of the rectangular spray pipe 50, and a support frame 53 fixedly installed on the upper end of the rectangular spray pipe 50. The upper end of the support frame 53 is fixedly connected to the inner top wall of the heat preservation box 10. The upper end of the connecting pipe 52 is connected to the interior of the first water supply copper pipe 30. A first solenoid valve 33 is fixedly installed on the surface of the first water supply copper pipe 30, and a second solenoid valve 54 is fixedly installed on the surface of the connecting pipe 52. When the first solenoid valve 33 is closed and the second solenoid valve 54 is opened, the water in the first water supply copper pipe 30 will enter the rectangular spray pipe 50 and be discharged by the spray head 51 to spray the Torreya grandis seedlings. The warm water in the first water supply copper pipe 30 is used for spraying, avoiding root cold stress caused by traditional cold water irrigation.

[0043] Specifically, the working principle and operation method of this utility model are as follows:

[0044] Temperature control process: The electric heating rod 21 raises the water temperature in the water storage tank 20 to the set value. The water pump 42 drives the hot water to flow sequentially through the second water supply copper pipe 31 → the first water supply copper pipe 30 → the spiral heat dissipation copper pipe 70 → the third water supply copper pipe 32. The temperature inside the heat preservation box 10 is stabilized at a constant temperature through the heat radiation of the copper pipes.

[0045] Humidity and spraying work together

[0046] Humidity control: The temperature and humidity monitor 80 detects the moisture content of the substrate. When the humidity is below 60%, the first solenoid valve 33 is closed and the second solenoid valve 54 is opened. Warm water enters the spray head 51 through the connecting pipe 52 and is atomized and sprayed. The humidity error is controlled within ±5%.

[0047] Coupling of supplemental lighting and heat dissipation

[0048] When the plant grow light 62 is turned on, it generates heat. The surface temperature of the lamp cover 61 is carried away by the circulating water through the spiral heat dissipation copper pipe 70. The waste heat of the lamp cover 61 is recovered and returned to the water storage tank 20 through the third water supply copper pipe 32, reducing the energy consumption of the electric heating rod 21.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
