Therefore, they should not be construed as limitations on this utility model.

[0025] like Figures 1-2 As shown, an automatic greenhouse temperature control device for ecological agriculture includes a greenhouse body 1, with two hinged doors 2 on the greenhouse body 1, two ventilation openings on both sides of the greenhouse body 1, a support rod 4 inside the greenhouse body 1, a temperature sensor 5 on the surface of the support rod 4, a heater 3 inside the greenhouse body 1, a ventilation mechanism 6 on the greenhouse body 1 to accelerate air circulation, and a blocking mechanism 7 inside the greenhouse body 1 to block the ventilation openings, with two sets of blocking mechanisms 7. A control terminal 8 is mounted on the surface of the support rod 4, and a display screen 9 is mounted on the front of the greenhouse body 1. In this embodiment, the heater 3 is specifically a steam-powered light-tube radiator, which works based on the principles of heat conduction and convection. It transfers heat to the surface of the radiator through internally flowing steam, thereby heating the surrounding air and raising the temperature inside the greenhouse. Its structural feature is the use of a light-tube design, which reduces thermal resistance and improves thermal efficiency. It is widely used for heating in greenhouses. The display screen 9 mainly displays the crops grown inside. Product information and temperature display: During use, the temperature sensor 5 monitors the temperature inside the greenhouse body 1. If the temperature is too high, the information data is transmitted to the control terminal 8. The control terminal 8 then activates the ventilation mechanism 6 and two sets of shielding mechanisms 7. The two sets of shielding mechanisms 7 unblock the vents, allowing air circulation inside the greenhouse body 1. The ventilation mechanism 6 draws in outside air, increasing the efficiency of air circulation and improving the efficiency of heat dissipation inside the greenhouse body 1, thus achieving a cooling effect. When the temperature drops to a specified value, the control terminal 8 stops the ventilation mechanism 6, and the shielding mechanisms 7 reset, continuing to shield the vents. When the temperature is low, the temperature sensor 5 transmits the information data to the control terminal 8, which then activates the heater 3 to increase the heat inside the greenhouse body 1, raising its temperature to a specified value. When the temperature drops to the specified value, the control terminal 8 stops the heater 3. This allows for automatic temperature control inside the greenhouse body 1 without manual operation, making it highly practical.

[0026] like Figures 1-3As shown, the ventilation mechanism 6 includes two fixed frames 601, which are respectively fixedly installed on both sides of the greenhouse body 1 and correspond to the ventilation openings. Each of the two fixed frames 601 is fitted with an insect-proof net 602, and the fixed frames 601 and the insect-proof net 602 are fixed together with screws. In this embodiment, the insect-proof net 602 is set to prevent insects from entering when the greenhouse body 1 is ventilated.

[0027] like Figures 3-4 As shown, three mounting frames 603 are fixedly installed inside the left fixed frame 601. A fixed rod 604 is fixedly installed on one side of each of the three mounting frames 603. A cross shaft 605 is rotatably installed on each of the three fixed rods 604. A fan blade 606 is fixedly installed on the right side of each of the three cross shafts 605. In this embodiment, when the three cross shafts 605 rotate simultaneously, the three fan blades 606 rotate accordingly, drawing outside air into the interior of the greenhouse body 1, accelerating the air circulation inside, and thus accelerating the loss of temperature inside the greenhouse body 1, achieving a cooling effect.

[0028] like Figures 3-4 As shown, a first synchronous pulley 607 is fixedly installed on the left side of the first cross shaft 605; a second synchronous pulley 608 is fixedly installed on the left side of the second cross shaft 605; a first synchronous belt 611 is provided on the outer wall of the first synchronous pulley 607 and the second synchronous pulley 608; a third synchronous pulley 609 is fixedly installed on the left side of the third cross shaft 605; a fourth synchronous pulley 610 is fixedly installed on the left side of the second synchronous pulley 608; a second synchronous belt 612 is provided on the outer wall of the third synchronous pulley 609 and the fourth synchronous pulley 610; and a second synchronous belt 612 is fixedly installed inside the left fixed frame 601. A support base 613 is provided, and a motor 614 is provided on the top of the support base 613. The fourth synchronous pulley 610 is provided at the output end of the motor 614. In this embodiment, the motor 614 is stably supported by the support base 613. When the motor 614 is started, it drives the fourth synchronous pulley 610 to rotate, and the second synchronous pulley 608 rotates accordingly. With the cooperation of the first synchronous belt 611 and the second synchronous belt 612, the first synchronous pulley 607, the second synchronous pulley 608, the third synchronous pulley 609 and the fourth synchronous pulley 610 rotate synchronously, and the three cross shafts 605 rotate accordingly.

[0029] like Figure 2 As shown, the shielding mechanism 7 includes a long plate 701, which is fixedly installed on the inner wall of the greenhouse body 1. A cylinder 702 is provided on the top of the long plate 701, and a shielding plate 703 is provided on the telescopic end of the cylinder 702. The shielding plate 703 is in contact with the greenhouse body 1. In this embodiment, when the cylinder 702 is activated, the shielding plate 703 is moved upward, which will block the ventilation opening and prevent the temperature inside the greenhouse body 1 from being lost.

[0030] like Figure 2As shown, the number of cylinders 702 is set to two and they are symmetrically distributed. In this embodiment, the stability of the lifting and lowering of the baffle plate 703 is improved by setting the number of cylinders 702.

[0031] In summary, the heater 3 is specifically a steam-powered radiator with a flat tube. Its working principle is based on heat conduction and convection. It transfers heat to the radiator surface through internally flowing steam, thereby heating the surrounding air and raising the temperature inside the greenhouse. Its structural feature is the use of a flat tube design, which reduces thermal resistance and improves thermal efficiency. It is widely used for heating in greenhouses. The display screen 9 mainly displays information about the products grown inside and the temperature. During use, the temperature sensor 5 monitors the temperature inside the greenhouse body 1. If the temperature is too high, the information data is transmitted to the control terminal 8. The control terminal 8 activates the ventilation mechanism 6 and the two sets of shielding mechanisms 7. The shielding mechanisms 7 unblock the ventilation openings, allowing air circulation within the greenhouse body 1. The ventilation mechanism 6 draws in outside air, increasing air circulation efficiency and improving the efficiency of heat dissipation within the greenhouse body 1, thus achieving a cooling effect. When the temperature drops to a specified value, the control terminal 8 stops the ventilation mechanism 6, and the shielding mechanisms 7 reset, resuming their shielding of the ventilation openings. When the temperature is low, the temperature sensor 5 transmits information data to the control terminal 8, which then activates the heater 3 to increase the temperature of the greenhouse body 1. The heat inside the greenhouse body 1 is used to raise its temperature to a specified value. When the temperature drops to the specified value, the control terminal 8 will stop the heater 3 from operating, thus enabling automatic temperature control inside the greenhouse body 1 without manual operation. This is highly practical. The insect-proof net 602 prevents insects from entering the greenhouse body 1 during ventilation. When the three cross shafts 605 rotate simultaneously, the three fan blades 606 rotate accordingly, drawing outside air into the interior of the greenhouse body 1, accelerating air circulation and reducing heat loss from the greenhouse body 1. As a result, the motor 614 is stably supported by the support base 613. When the motor 614 is started, it drives the synchronous pulley four 610 to rotate, and the synchronous pulley two 608 rotates accordingly. With the cooperation of the synchronous belt one 611 and the synchronous belt two 612, the synchronous pulley one 607, the synchronous pulley two 608, the synchronous pulley three 609 and the synchronous pulley four 610 rotate synchronously. The three cross shafts 605 rotate accordingly, start the cylinder 702, and drive the shield 703 to move upward, which will block the ventilation opening and prevent the temperature inside the greenhouse body 1 from being lost. By setting the number of cylinders 702, the stability of the lifting and lowering of the shield 703 is improved.
