Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine planting technology, specifically a drought-resistant and cold-proof device for traditional Chinese medicine planting. Background Technology

[0002] In the cultivation of Chinese medicinal herbs, cold winters and droughts in summer are two major adverse factors affecting their growth. Low winter temperatures can cause the plants to freeze, affecting their growth and even causing death; high summer temperatures can cause soil moisture to evaporate too quickly, leading to water shortages in the herbs, which is also detrimental to their growth.

[0003] In winter, low temperatures pose a serious threat to the growth of traditional Chinese medicinal herbs. Many varieties are susceptible to frost damage, leading to slow growth, poor development, and even death. For example, the roots of some rhizome herbs, such as ginseng and astragalus, are easily damaged by frost at low temperatures, affecting their growth and yield the following year. Common winter protection measures include covering with insulating materials such as straw and plastic film. However, these methods have some significant limitations:

[0004] High maintenance costs: Covering the insulation material requires regular manual inspection and maintenance to ensure its integrity and effectiveness. Under severe weather conditions, such as strong winds and blizzards, the insulation material is easily damaged and needs frequent replacement.

[0005] Unstable heat supply: Insulation materials alone cannot provide a continuous and stable heat supply. In extreme cold weather, the insulation effect of insulation materials is limited and cannot effectively protect medicinal plants from frost damage.

[0006] Inconvenient to operate: Covering and removing insulation materials requires a lot of manpower and time, especially in the case of large-scale planting, which is very inconvenient to operate. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a drought-resistant and cold-proof device for Chinese medicinal herb cultivation, which solves the problem of limitations in existing cold-resistant methods for Chinese medicinal herb cultivation mentioned in the background art.

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: A drought-resistant and cold-proof device for Chinese medicinal herb cultivation, comprising a support frame, a heating chamber, and a heat exchange tube. The heating chamber is installed on the top of the support frame and is filled with water. A sealing cover is fixedly installed on the top of the heating chamber. A heating rod is installed inside the heating chamber. A circulation pump is bolted to the bottom of the heating chamber. The input end of the circulation pump is connected to the inside of the heating chamber. The output end of the heating rod is connected to the heat exchange tube. The heat exchange tube is installed on the top of the Chinese medicinal herb cultivation space via an external support frame. The other end of the heat exchange tube is connected to the inside of the heating chamber and extends upward inside the heating chamber, away from the water inlet of the heat exchange tube. A control valve is provided at the water outlet end of the heat exchange tube. A nozzle is provided at the bottom of the heat exchange tube, and the inside of the nozzle is connected to the inside of the heat exchange tube.

[0009] Preferably, the heat exchange tube is made of copper-aluminum composite material and has a multi-bend structure. The use of copper-aluminum composite material and the multi-bend structure significantly improves heat exchange efficiency. The copper-aluminum composite material combines the high thermal conductivity of copper with the lightweight and corrosion resistance of aluminum, allowing the heat exchange tube to reduce the weight of the device while ensuring efficient heat conduction and enhancing its durability in complex environments. The multi-bend structure greatly increases the contact area between the heat exchange tube and the surrounding air, enabling heat to be transferred to the fins more evenly and quickly, thereby heating the entire medicinal herb planting space. This effectively improves heating efficiency, ensuring a stable supply of heat to the medicinal herbs quickly in low-temperature winter conditions, guaranteeing their normal growth. It also facilitates the even distribution of water flow within the heat exchange tube during summer, providing better support for the spray water replenishment function.

[0010] Preferably, the heat exchange tube is provided with fins on its exterior, and the fins are welded to the heat exchange tube. Multiple fins are provided and distributed in a straight line with equal spacing. This increases the surface area of ​​the heat exchange tube, significantly improving heat transfer efficiency. The welded connection between the fins and the heat exchange tube ensures that heat can be transferred quickly and evenly from the heat exchange tube to the fins, while the equal spacing of the multiple fins further optimizes the heat dissipation process, allowing heat to spread more evenly within the planting space, thus providing more effective cold protection for the medicinal herbs.

[0011] Preferably, the nozzle includes a connecting pipe connected to the bottom of the heat exchange tube, and one end of the connecting pipe is connected to the outer shell. The inside of the connecting pipe is in communication with the inside of the outer shell. A baffle is provided inside the outer shell, and a spring is provided at the bottom of the baffle. The bottom of the spring is fixedly connected to the top of the connecting block. A water outlet is fixedly installed at the bottom of the connecting block. The outer wall of the water outlet has multiple holes and slots distributed in an annular pattern at equal intervals. Only when the control valve is closed and the pressure inside the heat exchange tube increases, can the water flow overcome the elastic force of the spring and push the baffle downward, so that the water flow enters the water outlet through the connecting block and is evenly sprayed out from the multiple holes and slots of the water outlet, thereby achieving uniform water replenishment to the soil for planting Chinese medicinal herbs and improving drought resistance.

[0012] Preferably, the inner wall of the outer shell is provided with two protruding structures, and the inner wall of the outer shell is slidably connected to both sides of the baffle through the protruding structures. The baffle has notches on both sides, so that the baffle can slide smoothly on the protruding structures of the inner wall of the outer shell. There is a gap between the baffle and the inner wall of the outer shell for water to flow through.

[0013] Preferably, the connecting block has a hollow internal structure, and the outer wall of the connecting block has holes and grooves that are distributed in an annular and equally spaced pattern; this allows water to flow from the heat exchange tube through the connecting pipe into the hollow interior of the connecting block, and then flow evenly to the outlet head through the annular and equally spaced holes and grooves on its outer wall.

[0014] This invention provides a drought-resistant and frost-protective device for the cultivation of Chinese medicinal herbs. It has the following beneficial effects:

[0015] This is a drought-resistant and frost-protective device for Chinese medicinal herb cultivation. In the cultivation environment, the device uses an external support to fix the heat exchange tubes to the top of the cultivation space. During low winter temperatures, the heating rods activate, heating the water in the heating chamber to the set temperature. Then, a circulating pump pumps the hot water into the heat exchange tubes, transferring heat to the fins, which then release the heat into the cultivation space, effectively preventing the medicinal herbs from freezing. The cooled water flows back to the heating chamber through the other end of the heat exchange tubes, achieving recycling. During high summer temperatures, soil moisture evaporates rapidly. At this time, the control valve is closed, blocking the water flow loop in the heat exchange tubes. The circulating pump continues to operate, continuously pumping water from the heating chamber into the heat exchange tubes. The pressure inside the tubes increases, causing the baffles and springs to move downwards. Water flows through the gaps on the outside of the baffles into the outer shell, and then through the connecting block and the water outlet to spray onto the soil, replenishing the soil for medicinal herb cultivation and achieving drought resistance.

[0024] In this embodiment, when the device is used, the heat exchange tube 5 is installed on the top of the space for planting Chinese medicinal herbs through the external support 1. Then, when the temperature is low in winter, the water inside the heating chamber 2 is heated by the heating rod 9. After the water is heated to the specified temperature by the heating rod 9, the water inside the heating chamber 2 can be pumped into the heat exchange tube 5 under the action of the circulation pump 4. Then, the heat inside the heat exchange tube 5 can be transferred to the fins 8. The fins 8 can heat the inside of the Chinese medicinal herb planting space, thereby achieving the effect of stabilizing and preventing cold for the Chinese medicinal herbs.

[0025] Example 2:

[0026] Please see Figure 1-4 This utility model provides a technical solution: the nozzle 6 includes a connecting pipe 601, which is connected to the bottom of the heat exchange pipe 5, and one end of the bottom of the connecting pipe 601 is connected to the outer shell 602. The inside of the connecting pipe 601 is connected to the inside of the outer shell 602.
