However, existing cultivation devices are difficult to effectively simulate the impact of wind force from different wind directions on the growth of high-altitude vegetation seedlings. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a cold- and drought-resistant cultivation device for plateau vegetation is provided to solve the problem that existing cultivation devices cannot effectively simulate the impact of wind force from different wind directions on the growth of plateau vegetation seedlings.

[0004] A cold- and drought-resistant cultivation device for plateau vegetation includes: planting plateau vegetation seedlings in soil in a cultivation container with suitable humidity; cooling the seedlings and then allowing them to flow upwards via a fan, pass through a dehumidification box for dehumidification, and then be transported to an air duct; at this time, a motor controls a rotating column to rotate, so that the plateau vegetation seedlings in the cultivation box are subjected to low-temperature winds from the side and top directions blown by the exhaust plate, providing low-temperature, drought, and strong wind environmental simulation conditions for the growth of plateau vegetation seedlings in the cultivation box, which facilitates the simulation effect of natural environmental conditions of the cultivation device and improves the cultivation quality of plateau vegetation cultivation device.

The upper surface of the vegetation cultivation box is connected to a rotating column via a bearing. A motor is connected to the surface of the rotating column via a gear meshing assembly. An exhaust plate is fixed to the lower end of the rotating column. An exhaust mesh opening 1 and an exhaust mesh opening 2 are distributed on the lower and side surfaces of the exhaust plate. An air guide pipe is installed through the inner side of the rotating column. The air guide pipe is connected to a fan via an air supply pipe. The lower end of the fan is connected to a dehumidification box. A perforated moisture-absorbing mesh plate is inserted into the dehumidification box. A refrigeration device is connected to the lower end of the dehumidification box. The inner side of the refrigeration device is connected to the vegetation cultivation box via a cooling chamber.

[0006] Furthermore, culture vessels are inserted into the inner side of the ventilation frame; and the culture vessels are arranged in a circular pattern. A collection tray is placed at the lower end of the ventilation frame.

[0011] Furthermore, the air duct is connected to exhaust port one and exhaust port two through the diversion cavity. Beneficial effects

[0012] This utility model's plateau vegetation cold- and drought-resistant cultivation device utilizes an exhaust plate, air guide pipe, rotating column, gear meshing assembly, and motor to form a rotary blower mechanism. The rotating column drives the exhaust plate to rotate and exhaust air. A fan at a certain speed delivers the low-temperature airflow, cooled and dehumidified by the refrigeration equipment and dehumidification box, to the exhaust plate mesh opening for discharge. This allows the plateau vegetation seedlings in the cultivation container to be exposed to low-temperature airflow from the sides and above, facilitating efficient multi-directional low-temperature airflow.

[0018] Reference Figures 1 to 4 As shown, this utility model provides a cold and drought resistant cultivation device for plateau vegetation, including: a vegetation cultivation box 1, and a ventilation board frame 11 inserted into the vegetation cultivation box 1; The upper end of the vegetation cultivation box 1 is connected to a rotating column 22 via a bearing. The surface of the rotating column 22 is connected to a motor 24 via a gear meshing assembly 23. An exhaust plate 2 is fixed at the lower end of the rotating column 22. An exhaust mesh outlet 1 27 and an exhaust mesh outlet 28 are distributed on the lower end and side end of the exhaust plate 2. An air guide pipe 21 is installed through the inner side of the rotating column 22. The air guide pipe 21 is connected to a fan 5 via an air supply pipe 51. The lower end of the fan 5 is connected to a dehumidification box 4. A porous moisture-absorbing mesh plate 42 is inserted into the dehumidification box 4. A refrigeration device 3 is connected to the lower end of the dehumidification box 4. The inner side of the refrigeration device 3 is connected to the vegetation cultivation box 1 via a cooling chamber 31.

[0019] First, the highland vegetation seedlings are planted in soil in a cultivation container 12 with suitable humidity. The cultivation container 12 is then placed on the ventilation rack 11 inside the vegetation cultivation box 1. The door of the vegetation cultivation box 1 is closed, and the cooling temperature of the refrigeration equipment 3 and the speed of the fan 5 are set. This allows the air inside the vegetation cultivation box 1 to flow into the cooling chamber 31 of the refrigeration equipment 3. After cooling, the air flows upward through the fan 5, passes through the dehumidification box 4 for dehumidification, and is then transported to the air duct 21. At this time, the motor 24 controls the rotating column 22 to rotate, so that the low-temperature air entering through the air duct 21 is transported to the exhaust vent 27 and exhaust vent 28 of the exhaust plate 2. This allows the highland vegetation seedlings inside the vegetation cultivation box 1 to be exposed to the low-temperature wind blowing from the side and top of the exhaust plate 2, providing a low-temperature, arid, and windy environment for the growth of the highland vegetation seedlings inside the vegetation cultivation box 1. This enhances the simulation effect of the natural environment conditions of the cultivation device and improves the cultivation quality of the highland vegetation cultivation device.

[0020] In this embodiment, a culture dish 12 is inserted into the inner side of the ventilation frame 11; and the culture dish 12 is arranged in a circular pattern. A collection tray 13 is placed at the lower end of the ventilation frame 11. A supplementary light 15 is installed on the upper inner wall of the plant cultivation box 1, and a ventilation slot 14 is opened on the right end face of the plant cultivation box 1; and the ventilation slot 14 is connected to the cooling chamber 31.

[0021] In a preferred embodiment, the cultivation container 12 is used for transplanting and cultivating highland vegetation seedlings. The waste tray 13 catches soil and other debris that falls from the cultivation container 12, facilitating daily cleaning. The supplemental lighting 15 provides suitable light for the growth of the highland vegetation seedlings. The vegetation cultivation box 1 uses a ventilation slot 14 on the right side to allow air inside the box to enter the refrigeration equipment 3 for cooling before returning it to the box, ensuring that the highland vegetation seedlings inside the cultivation box 1 grow and are cultivated in a low-temperature environment.

[0022] In this embodiment, the refrigeration device 3 contains a refrigeration device group 33, and a heat exchange tube 32 is arranged around the outside of the cooling cavity 31; and the heat exchange tube 32 is connected to the refrigeration device group 33.

[0023] As a preferred implementation, the refrigeration device group 33 mainly consists of components such as a compressor, condenser, throttling device, and evaporator. Through the phase change cycle of the refrigerant between the compressor, condenser, expansion valve and evaporator, heat is transferred from the low temperature environment to the high temperature environment. The low temperature refrigerant exchanges heat with the gas flowing in the cooling chamber 31 through the heat exchange tube 32, thereby reducing the temperature of the air inside the chamber.

[0024] In this embodiment, a motor 24 is fixedly supported on the upper surface of the vegetation cultivation box 1, and a gear meshing assembly 23 is shaft-connected to the lower end of the motor 24. A sealing cover plate 41 is screwed onto the front surface of the dehumidification box 4. The upper end of the air duct 21 is connected to the air supply duct 51 through a rotating pipe joint 25, and a diversion chamber 26 is opened on the inner side of the exhaust plate 2. The air duct 21 is connected to the first exhaust port 27 and the second exhaust port 28 through the diversion chamber 26.

[0025] In a preferred embodiment, the motor 24 drives the two sets of gears in the gear meshing assembly 23 to rotate, thereby causing the rotating column 22 to rotate, which in turn causes the lower exhaust plate 2 to rotate and move, thereby changing the exhaust direction of the exhaust plate 2. This allows the air supply duct 51 to deliver the dehumidified low-temperature airflow through the air guide duct 21 to the exhaust net outlet 27 and the exhaust net outlet 28, so that the highland vegetation seedlings in the cultivation container 12 are exposed to low-temperature winds blowing from the side and above.

[0026] This utility model of a cold- and drought-resistant cultivation device for plateau vegetation can effectively solve the problem that existing cultivation devices are unable to effectively simulate the impact of wind force from different wind directions on the growth of plateau vegetation seedlings. It can efficiently provide low-temperature winds from multiple directions, ensuring that plateau vegetation is in a cold- and drought-resistant cultivation environment with strong winds, enhancing the simulation effect of natural environmental conditions in the cultivation device, improving the cultivation quality of plateau vegetation cultivation devices, and is applicable to cold- and drought-resistant cultivation devices for plateau vegetation.
