Description

Technical Field

[0001] This utility model relates to the field of seedling sand bed technology, and in particular to a greenhouse humidity-controlled and heat-insulating seedling sand bed. Background Technology

[0002] In traditional greenhouse cultivation systems, seedling sand beds serve as the basic carrier for seedling cultivation. Their environmental temperature and humidity control system is relatively primitive, and they are highly correlated with the overall temperature and humidity environment of the greenhouse. During daily production operations, the greenhouse needs to maintain a relatively stable temperature and humidity environment to ensure plant growth.

[0003] Currently, in traditional greenhouse planting systems, there are multiple seedling sand beds inside the greenhouse. The existing seedling sand beds do not have independent isolation or temperature and humidity control equipment. Because the temperature and humidity of the seedling sand beds cannot be controlled independently, the entire greenhouse space needs to be treated as the object of regulation when adjusting the temperature and humidity of the seedling sand beds, which results in a large waste of energy. Utility Model Content

[0005] To achieve the above objectives, this utility model provides a humidity-controlled and heat-insulating seedling sand bed in a greenhouse, including a seedling planting trough and a humidity-controlled and heat-insulating component. The humidity-controlled and heat-insulating component includes a sand bed frame, a top film, two gable films, two side covering film components, a mist spray component, a drip irrigation component, and a humidifying component.

[0020] This utility model provides a humidity-controlled and heat-insulating seedling sand bed for greenhouse cultivation, including a seedling planting trough 101 and a humidity-controlled and heat-insulating component. The humidity-controlled and heat-insulating component includes a sand bed frame 102, a top film 103, two gable films 104, two side film covering components 105, a mist spraying component 106, a drip irrigation component 107, and a humidifying component 120. The side film covering component 105 includes a climbing guide rod 108, a film rolling device 109, a film rolling rod 110, and a side film 111. The mist spraying component 106 includes an LDP (Liquid Dioxide Discharge Machining). The system includes an E-sprinkler pipe 112, multiple first hose clamps 113, multiple anti-drip atomizing nozzles 114, a first polyester line 115, a first bypass valve 116, and a second bypass valve 117; the drip irrigation component 107 includes a PVC pipe 118 and a drip irrigation interface 119; the humidification component 120 includes multiple second hose clamps 121, a stainless steel pipe 122, a second polyester line 123, and multiple high-pressure cold mist nozzles 124; the aforementioned scheme allows for individual adjustment of temperature and humidity according to seedling needs, saving energy.

[0021] In this specific embodiment, the sand bed frame 102 is located on the side of the seedling planting trough 101; the top film 103 is fixedly connected to the sand bed frame 102 and located on the top of the sand bed frame 102; the two gable films 104 are respectively fixedly connected to the sand bed frame 102 and located on both sides of the sand bed frame 102; the two side covering film components 105 are mirror images of each other on both sides of the sand bed frame 102; the mist spray component 106 is disposed on the sand bed frame 102; the drip irrigation component 107 is disposed on the seedling planting trough 101; and the humidification component 120 is disposed on the sand bed frame 102. The sand bed frame 102 is constructed using hot-dip galvanized steel pipes. Based on the actual usable area and design requirements of the sand bed, hot-dip galvanized steel pipes of appropriate diameter and wall thickness are selected for cutting and welding to form a stable sand bed frame 102 shape, such as a rectangle or other common shapes, providing a supporting foundation for the entire sand bed. The top film 103 and the gable film 104 are made of films with high light transmittance and anti-aging properties as covering materials. Grooves are provided at the edges of the sand bed frame 102. After the top film 103 and the gable film 104 are laid on the sand bed frame 102, spring clips are inserted into the grooves to fix the top film 103 and the gable film 104, ensuring that the top film 103 and the gable film 104 are firmly installed and flat, without wrinkles or damage. The two side-covering film components 105 can unfold and roll up the film to seal the sand bed frame 102; the misting component 106 can spray out atomized water droplets, evenly spraying them onto the seedlings in the seedling planting trough 101, with the water mist evenly diffused throughout the sand bed space, providing a suitable humidity environment for the seedlings; the drip irrigation component 107 can be connected to a drip irrigation device for drip irrigation of the seedlings. The humidifying component 120 can cause water to form natural particles of 1-15 micrometers, which diffuse throughout the space. The water mist absorbs heat in the air, changing from a liquid to a gaseous state, increasing the humidity of the space and achieving the purpose of lowering the air temperature. Through the above methods, the temperature and humidity can be adjusted individually according to the needs of seedling cultivation, eliminating the need to adjust the temperature and humidity of the entire greenhouse, thus saving energy. Furthermore, by adjusting the temperature and humidity of the seedling sand bed individually, compared to adjusting the temperature and humidity of the entire greenhouse, this application also allows for more precise temperature and humidity control.

[0022] The climbing guide rod 108 is fixedly connected to the sand bed frame 102 and is located on the side of the sand bed frame 102; the film winding device 109 is located on the side of the climbing guide rod 108, and the film winding rod 110 is located on the side of the film winding device 109; the side film 111 is fixedly connected to the film winding rod 110 and is located on the side of the film winding rod 110. Two side films 111 and two gable films 104 surround the sand bed frame 102. Workers rotate the handle of the film roller 109 in the forward direction, causing the film roller rod 110 to rotate and roll up the film fixed to the film roller rod 110, thus opening the window. Simultaneously, the film roller 109 rises upwards along the climbing guide rod 108 as the film roller rod 110 rotates. Reverse rotation of the handle of the film roller 109 causes the film roller rod 110 to rotate and unfold the film wrapped around it, thus closing the window. Simultaneously, the film roller 109 moves downwards along the climbing guide rod 108 as the film roller rod 110 rotates. When ventilation is needed, the operator manually rotates the handle of the film roller 109, causing the film roller 109 to roll up the film, thus adjusting the opening size of the ventilation opening. The film roller 109 is existing technology.

[0023] Secondly, the LDPE irrigation pipe 112 is disposed inside the sand bed frame 102; multiple first hose clamps 113 are respectively disposed on the sides of the LDPE irrigation pipe 112 and the sand bed frame 102; multiple anti-drip atomizing nozzles 114 are respectively fixedly connected to and communicate with the LDPE irrigation pipe 112, and are respectively located on the sides of the LDPE irrigation pipe 112. The LDPE irrigation pipe 112 is fixed to the sand bed frame 102 by the first hose clamps 113. The LDPE irrigation pipe 112 is connected to an external water source. The anti-drip atomizing nozzles 114 can spray out tiny water droplets atomized from water, which are evenly sprayed onto the seedlings on the seedling planting trough 101. The water mist is evenly diffused throughout the sand bed space, providing a suitable humidity environment for the seedlings.

[0024] Meanwhile, the first polyester line 115 is disposed on the side of the LDPE irrigation pipe 112 and the sand bed frame 102; the first bypass valve 116 is fixedly connected to the LDPE irrigation pipe 112 and located at the front end of the LDPE irrigation pipe 112; the second bypass valve 117 is fixedly connected to the LDPE irrigation pipe 112 and located at the end of the LDPE irrigation pipe 112. Connecting the LDPE irrigation pipe 112 to the sand bed frame 102 using the first polyester line 115 improves the installation stability of the LDPE irrigation pipe 112. The first bypass valve 116 controls the connection and closure of the LDPE irrigation pipe 112, and the second bypass valve 117 can be used for the periodic flushing and maintenance of the LDPE irrigation pipe 112.

[0025] In addition, the PVC pipe 118 is disposed inside the seedling planting trough 101; the drip irrigation interface 119 is fixedly connected to and communicates with the PVC pipe 118, and is located on the side of the PVC pipe 118. The PVC pipe 118 can be connected to a drip irrigation device, and the drip irrigation interface 119 can be used for drip irrigation of seedlings.

[0026] Finally, multiple second hose clamps 121 are respectively disposed on the side of the sand bed frame 102; the stainless steel pipe 122 is disposed on the multiple second hose clamps 121; the second polyester thread 123 is disposed on the side of the sand bed frame 102 and the stainless steel pipe 122; multiple high-pressure cold mist nozzles 124 are respectively fixedly connected to and communicate with the stainless steel pipe 122, and are respectively located on the side of the stainless steel pipe 122. The second hose clamps 121 are used to connect the sand bed frame 102 and the stainless steel pipe 122, and the second polyester thread 123 is wound around the sand bed frame 102 and the stainless steel pipe 122 to connect the sand bed frame 102 and the stainless steel pipe 122. High-pressure water enters the stainless steel pipe 122, and the high-pressure cold mist nozzles 124 can make the water form natural particles of 1-15 micrometers, which diffuse throughout the space. The water mist absorbs heat in the air, changes from liquid to gas, increases the humidity of the space, and achieves the purpose of lowering the air temperature.

[0027] In using this invention, the sand bed frame 102 provides a supporting foundation for the entire sand bed. The top film 103, the gable film 104, and the side film 111 are made of films with high light transmittance and anti-aging properties as covering materials. The high light transmittance of the film allows more natural light to penetrate into the sand bed during the day, providing sufficient light conditions for seedling photosynthesis and promoting seedling growth. Its anti-aging properties ensure that the film is not easily aged or damaged under the influence of environmental factors such as long-term light exposure and temperature and humidity changes, maintaining a good covering and heat preservation effect. When ventilation is required, the operator manually rotates the handle of the film roller 109, which rolls up the film to adjust the opening size of the ventilation opening, providing a suitable air circulation environment for the seedlings in a timely manner, promoting gas exchange, and reducing the occurrence of pests and diseases. The anti-drip atomizing nozzle 114 sprays out tiny water droplets, evenly covering the seedlings in the seedling planting trough 101. The water mist evenly diffuses throughout the sand bed space, providing a suitable humidity environment for the seedlings. Furthermore, because the water droplets are extremely small, the process of increasing humidity will not cause any impact or damage to surrounding objects. High-pressure water enters the stainless steel pipe 122, and the high-pressure cold mist nozzle 124 can form water into natural particles of 1-15 micrometers, which diffuse throughout the space. The water mist absorbs heat in the air, changing from a liquid to a gaseous state, increasing the humidity and lowering the air temperature. The drip irrigation interface 119 can be connected to a drip irrigation device for drip irrigation of the seedlings, meeting the water needs of the sand bed under different conditions. Through the above methods, temperature and humidity can be adjusted individually according to seedling needs, eliminating the need to adjust the temperature and humidity of the entire greenhouse, saving energy. Moreover, by adjusting the temperature and humidity of the seedling sand bed individually, compared to adjusting the temperature and humidity of the entire greenhouse, this application also allows for more precise temperature and humidity control.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
