Description

Technical Field

[0001] This utility model relates to the field of fresh corn seedling technology, and in particular to a constant temperature cultivation device for fresh corn seedling trays with an insulation layer. Background Technology

[0002] Fresh corn refers to corn harvested at the milk stage (kernel moisture content approximately 60%-70%), eaten directly or processed as fresh, tender ears. It is also known as sweet corn, waxy corn, etc. Its characteristics include high sugar content, a sweet and soft texture, and rich nutrition, including protein, vitamins, dietary fiber, and various antioxidants. Unlike traditional kernel corn, fresh corn emphasizes its fresh flavor and marketability, requiring prompt sale or processing after harvest to maintain optimal taste. It is mainly divided into three categories: sweet corn, waxy corn, and sweet-waxy corn.

[0003] Traditional seedling cultivation relies on overall greenhouse heating and small arched sheds for covering. Heat loss is rapid, and it is impossible to provide a stable and uniform root zone temperature for each seedling tray. At night or when cold waves arrive, the insulation effect of plastic film alone is limited, and local low temperatures are likely to occur in the seedbed, resulting in uneven germination, slow seedling growth, or even cold damage. In addition, moisture accumulates in the small arched sheds, and the temperature drops sharply when ventilating, which can easily cause diseases such as damping-off. This creates a contradiction between heat preservation and disease prevention.

[0004] Therefore, it is necessary to design a constant temperature cultivation device for fresh corn seedling trays with an insulation layer to solve the above-mentioned technical problems. Summary of the Invention

[0005] To overcome the shortcomings of traditional seedling cultivation methods that rely on greenhouses and small arched sheds, which have poor heat preservation, rapid heat dissipation, uneven root zone temperature, and are prone to uneven emergence, slow growth, or cold damage, as well as the contradiction between moisture accumulation and ventilation and cooling, which can easily lead to diseases, this utility model provides a constant temperature cultivation device for fresh corn seedling trays with an insulation layer.

[0006] The technical solution of this utility model is as follows: a constant temperature cultivation device for fresh corn seedling trays with an insulation layer, comprising a cultivation cabinet, a sealed door, a handle, a display screen, control buttons, a latch, a first insulation partition, a second insulation partition, a filter screen, a fixing plate, an electric heating tube, a temperature sensor, a sliding frame, a pull rod, and a seedling board. The front of the cultivation cabinet is rotatably connected to the sealed door, the right side of the sealed door is fixedly connected to the handle, the front of the sealed door is fixedly connected to the display screen, and multiple control buttons are fixedly connected in a linear array at the front of the sealed door. The display screen is electrically connected to all of the multiple control buttons. The cultivation cabinet and the right side of the sealed door... Both sides of the compartment are fixedly equipped with latches. The rear of the sealed door is embedded with a first heat-insulating partition. Three sides of the inside of the cultivation cabinet are embedded with a second heat-insulating partition. A filter screen is fixedly connected inside the cultivation cabinet. A fixing plate is fixedly connected inside the cultivation cabinet. An electric heating tube is fixedly connected to the bottom of the fixing plate. Four temperature sensors are fixedly connected inside the cultivation cabinet. All four temperature sensors are electrically connected to the display screen. Multiple sliding frames are vertically distributed and slidably placed inside the cultivation cabinet. A pull rod is fixedly connected to the top of each sliding frame. A seedling board is slidably placed on the top of each sliding frame.

[0007] In one embodiment, each seedling board has a rectangular array of openings at the top, providing multiple seedling troughs.

[0008] In one embodiment, the first insulation partition and the three second insulation partitions are all made of polyurethane.

[0009] In one embodiment, the system also includes a mounting frame and fluorescent lights. The mounting frame is fixedly connected inside the cultivation cabinet, and multiple fluorescent lights are vertically and fixedly connected to the front of the mounting frame.

[0010] In one embodiment, the device also includes a one-way valve, a mounting frame, a motor, and fan blades. Four through holes are provided on both sides of the upper part of the cultivation cabinet. A one-way valve is fixedly connected to each through hole. Four mounting frames are fixedly connected in a linear array on both sides of the inside of the cultivation cabinet. A motor is fixedly connected inside each mounting frame. Each motor is electrically connected to a corresponding control button. The output shaft of each motor passes through the corresponding mounting frame and is fixedly connected to a fan blade.

[0011] In one embodiment, four motors on one side and four motors on the other side are symmetrically distributed.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention constructs a complete and efficient heat insulation layer by configuring a first heat insulation partition on the back side of the sealed door and a second heat insulation partition on the bottom side and the left and right sides of the inside of the cultivation cabinet. This heat insulation layer can significantly reduce the loss of internal heat to the external environment, so that the electric heating tube does not need to work continuously at high intensity to maintain the set temperature. Combined with the sealed space formed by the sealed door and the latch, it effectively solves the problem of large temperature fluctuation and rapid heat loss caused by poor heat insulation performance in traditional seedling cultivation methods.

[0013] 2. This utility model uses a motor to drive the fan blades to rotate at high speed, forming a uniform and stable forced convection airflow inside the cultivation cabinet. This allows the hot air to mix fully with the fresh air entering from the filter and be evenly distributed between each layer of seedling boards, achieving efficient heat and gas exchange.

[0023] Example: A constant temperature cultivation device for fresh corn seedling trays with an insulation layer, such as... Figures 1-7 As shown, the system includes a cultivation cabinet 1, a sealed door 2, a handle 3, a display screen 4, control buttons 5, latches 6, a first insulation partition 7, a second insulation partition 8, a filter screen 9, a fixing plate 10, an electric heating element 11, a temperature sensor 1101, a sliding frame 12, a pull rod 13, and a seedling board 14. The front of the cultivation cabinet 1 is rotatably connected to the sealed door 2. A handle 3 is screwed onto the right side of the sealed door 2. A display screen 4 is screwed onto the front side of the sealed door 2. Multiple control buttons 5 are screwed onto the lower front of the sealed door 2 in a linear array. The display screen 4 is electrically connected to all control buttons 5. Latches 6 are fixed on both the upper and lower sides between the cultivation cabinet 1 and the right side of the sealed door 2. A first insulation partition 7 is embedded in the rear of the sealed door 2 and glued to it. The first insulation partition 7 is... Made of polyurethane, the cultivation cabinet 1 has three second insulation partitions 8 embedded in the bottom and left and right sides of the interior, which are glued together. The upper inside of the cultivation cabinet 1 is fitted with a filter screen 9 by screws. The top inside of the cultivation cabinet 1 is fitted with a fixing plate 10 by screws. The bottom of the fixing plate 10 is fitted with an electric heating tube 11 by screws. The upper inside of the cultivation cabinet 1 is fitted with four temperature sensors 1101 by screws. All four temperature sensors 1101 are electrically connected to the display screen 4. Multiple sliding frames 12 are vertically distributed and slidably placed inside the cultivation cabinet 1. Each sliding frame 12 has a pull rod 13 welded to the front of its top. Each sliding frame 12 has a seedling board 14 slidably placed on its top. Each seedling board 14 has multiple seedling troughs in a rectangular array on its top.

[0024] like Figure 1 , Figure 6 , Figure 7 and Figure 8As shown, it also includes a fixing frame 15, fluorescent lamps 16, one-way valves 17, mounting frames 18, motors 19, and fan blades 20. The fixing frame 15 is installed on the rear side of the inside of the cultivation cabinet 1 by screws. Multiple fluorescent lamps 16 are vertically distributed and fixedly connected to the front side of the fixing frame 15. Four through holes are opened on the upper left and right sides of the inside of the cultivation cabinet 1. One-way valves 17 are installed in each through hole by screws. Four mounting frames 18 are installed in a linear array on the left and right sides of the inside of the cultivation cabinet 1 by screws. Motors 19 are installed in each mounting frame 18 by screws. The four motors 19 on the left and the four motors 19 on the right are symmetrically distributed. Each motor 19 is electrically connected to the corresponding control button 5. The output shaft of each motor 19 passes through the corresponding mounting frame 18 and is connected to the fan blades 20 by a coupling.

[0025] When this device is needed, the user first opens the sealed door 2 using handle 3, then places the seedling tray 14 containing corn seeds into each sliding frame 12 in sequence. The seedling tray allows for the neat placement of the seeds. After placement, the sealed door 2 is closed, and the lock 6 securely locks the sealed door 2 to the cultivation cabinet 1, forming a sealed cultivation space. At this time, the user can set the required cultivation temperature, light exposure time, and other parameters using control button 5. The display screen 4 will display the setting information and the current status inside the cabinet in real time. The heating element 11 starts working and generates heat. Since the heating element 11 is located in the cabinet... At the top, heat naturally diffuses downwards into the seedling space through convection and radiation. Simultaneously, motor 19 starts, and the output shaft fan blades 20 rotate at high speed. The four motors 19 on the left and four on the right are symmetrically distributed, working together to create a uniform and stable forced convection airflow within the cultivation cabinet 1. The rotating fan blades 20 blow the hot air generated by the heating element 11 into the interior space of the cultivation cabinet 1, agitating the internal air and forcing it to mix with the fresh air entering from the filter 9. This mixture is then evenly blown across each layer of seedling trays 14. This process greatly improves heat exchange efficiency and avoids heat loss. The temperature difference between the upper and lower layers caused by air accumulation at the top allows heat to be transferred to the seedling board 14 and the seeds within it via airflow, providing continuous and uniform heat for germination and growth. Temperature sensor 1101 monitors the temperature inside the cultivation cabinet 1 in real time, transmitting the data to display screen 4, which displays the temperature parameters. When the monitored temperature is below the set value, control button 5 maintains or activates the heating element 11 and motor 19. When the temperature reaches or exceeds the set value, the heating element 11 automatically shuts off to save energy or reduces its power, thus achieving constant temperature control. This is achieved through forced circulation by motor 19 and fan blades 20. During the process, gas exchange between the inside and outside of the cultivation cabinet 1 is carried out through the one-way valve 17 at the top. When the fan blades 20 agitate the airflow or temperature fluctuations cause local negative pressure, fresh air from outside is drawn into the cultivation cabinet 1 through the filter screen 9. The filter screen 9 can effectively filter dust and impurities in the air to ensure the cleanliness of the incoming air. The first heat insulation partition 7 behind the sealing door 2 and the second heat insulation partitions on the bottom and left and right sides of the inside of the cultivation cabinet 1 work together to greatly reduce the loss of heat from the inside of the cabinet to the external environment. This allows the heating tube 11 to maintain a constant internal temperature without continuous high-intensity operation, playing a key role in energy saving and consumption reduction.

[0026] Multiple fluorescent lamps 16 will light up at regular intervals to simulate natural light and provide the necessary light source for corn seedlings to photosynthesize. Users can monitor the temperature parameters inside the cabinet in real time through the display screen 4 on the sealed door 2 without opening the sealed door 2. When it is necessary to observe the growth of the seedlings or manage them, the sealed door 2 can be opened, and the pull rod 13 can be directly grasped to smoothly pull the entire sliding frame 12 along with the seedling board 14 on it forward. The operation is labor-saving and convenient.

[0027] When the seedling cultivation period ends and the seedlings need to be removed, first turn off the heating element 11, fluorescent lamp 16 and motor 19 by controlling button 5. After the temperature inside the cabinet naturally drops to a safe range, open the latch 6 and open the sealing door 2 through handle 3. Then, the user can pull out the slide frame 12 along with the seedling board 14 one by one through the pull rod 13 to complete the harvesting of seedlings. Finally, put the empty seedling board 14 back into the slide frame 12, push all the slide frames 12 back into their original positions inside the cultivation cabinet 1, close the sealing door 2 and lock the latch 6 to complete the reset process of the entire device and prepare it for the next use.
