Technical Field

[0001] This utility model relates to the field of greenhouse ventilation regulation technology, specifically an agricultural greenhouse ventilation regulation device. Background Technology

[0002] Greenhouses were originally specialized equipment for vegetable production, but their application has become increasingly widespread with the development of production. Currently, greenhouses are used for potted flowers and cut flowers; in fruit tree production, they are used to cultivate grapes, strawberries, watermelons, melons, peaches, and citrus fruits, etc.

[0003] According to patent application number CN202322471541.X, this utility model relates to the field of greenhouse cultivation and discloses an intelligent greenhouse automatic ventilation adjustment device. Under the action of a second spring, the sliding plate moves back, causing the cleaning brush to move back. This process repeats, and the cleaning brush moves back and forth to effectively clean the filter. In use, this utility model does not require manual adjustment, and the ventilation volume is different during the day and night, so it cannot be adjusted according to the day and night conditions.

However, the two application numbers mentioned above, CN202322471541.X and CN201820818774.9, require manual adjustment when ventilating the greenhouse. During the day, ventilation requires opening the top vents to expel hot air, while at night, ventilation requires opening the bottom vents to introduce cold air. The top vents need to be closed at night, and the bottom vents need to be closed during the day. Furthermore, the ventilation volume differs between day and night, making it inconvenient to adjust according to the day and night conditions. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a ventilation regulation device for agricultural greenhouses. This device solves the problem that when ventilating a greenhouse, the top vents need to be opened during the day to expel hot air, while the bottom vents need to be opened at night to introduce cool air. The top vents need to be closed at night, and the bottom vents need to be closed during the day. This requires manual adjustment, and the ventilation volume differs between day and night, making it inconvenient to adjust according to the daytime and nighttime conditions.

[0014] Beneficial effects

[0015] This utility model provides a ventilation and regulation device for agricultural greenhouses. Compared with the prior art, it has the following advantages:

[0016] 1. This agricultural greenhouse ventilation and regulation device allows air to circulate freely inside the glass greenhouse when the ventilation plate is at the top, as there are no obstructions. At night, a motor rotates the ventilation plate downwards, positioning it to the side of the fixed plate and cleaning rod. The fixed plate blocks the air vents on the surface of the ventilation plate, reducing the ventilation volume and creating a difference in ventilation volume between the top and bottom of the plate. The position can be adjusted, and an electric push rod allows the cleaning rod to enter the air vents, preventing blockage and ensuring ventilation. The ventilation volume is adjusted simultaneously, improving work efficiency and reducing manual operation.

[0017] 2. When the ventilation plate is located below the ventilation plate, the ventilation regulating device for agricultural greenhouses will maintain a certain distance between the cleaning rod and the ventilation plate, preventing the cleaning rod from blocking the air holes and ensuring that the gas can flow through the air holes.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4This utility model provides a technical solution: an agricultural greenhouse ventilation adjustment device, including a glass greenhouse body 1, with adjustment mechanisms 2 on both sides of the glass greenhouse body 1, and an installation plate 3 at the bottom of the adjustment mechanism 2, the installation plate 3 being fixedly connected to the glass greenhouse body 1.

[0026] The adjustment mechanism 2 includes a motor 201 located inside the glass enclosure 1. An adjustment plate 202 is provided at the end of the output shaft of the motor 201. The adjustment plate 202 is in contact with the glass enclosure 1. A ventilation plate 203 is embedded on the top surface of the adjustment plate 202. Air holes 204 are provided on the surface of the ventilation plate 203. A fixing plate 205 is provided on the side of the adjustment plate 202 away from the glass enclosure 1, and the fixing plate 205 is in contact with the adjustment plate 202. A push plate 206 is provided above the mounting plate 3. A cleaning rod 207 is provided on the side of the push plate 206 near the fixing plate 205. There are multiple cleaning rods 207 and air holes 204, and the number of cleaning rods 207 is equal. The cleaning rods 207 are fixedly connected to the push plate 206.

[0027] The inner wall of the glass canopy 1 is provided with a support rod 208. A crossbar 209 is fixedly installed on the top of the motor 201. The crossbar 209 is fixedly connected to the support rod 208. Both ends of the mounting plate 3 are provided with positioning pins 4, and the positioning pins 4 penetrate the mounting plate 3. One end of the glass canopy 1 is provided with a door panel 5. The door panel 5 is movably connected to the glass canopy 1 through a hinge. The top of the mounting plate 3 is provided with an electric push rod 210. One end of the electric push rod 210 is provided with a moving rod 211, and the moving rod 211 is fixedly connected to the push plate 206.

[0028] Please see Figure 1-2 5. A guide rod 212 is provided below the cleaning rod 207, and the guide rod 212 is fixedly connected to the glass canopy 1. The guide rod 212 passes through the push plate 206. The surface of the fixed plate 205 is provided with a hole 213. The top cleaning rod 207 extends into the interior of the hole 213. The cleaning rod 207 is adapted to the air hole 204. The diameter of the hole 213 is equal to that of the air hole 204.

[0029] During operation, the positioning pin 4 is first moved downwards, extending into the ground. The mounting plate 3 through which the positioning pin 4 passes is fixedly connected to the glass canopy 1, improving the stability of the glass pump body and facilitating long-term use. During daytime use, the motor 201 is used, and the motor 201 is fixedly connected to the support rod 208 via the crossbar 209 to prevent the motor 201 from falling downwards. The output shaft end of the motor 201 is connected to the adjusting plate 202, causing the adjusting plate 202 to rotate. Because the adjusting plate 202 is in contact with the glass canopy 1, This ensures the rotation of the adjusting plate 202, which in turn causes the ventilation plate 203 to rotate, moving it to the top. When the ventilation plate 203 is at the top, the lack of obstructions allows air to circulate inside the glass enclosure 1. For nighttime use, the motor 201 is also used. Since the ventilation plate 203 is at the top, the motor 201 allows the adjusting plate 202 to rotate 180 degrees, moving the ventilation plate 203 to the bottom and placing it to one side of the pushing plate 206. This ensures that a portion of the ventilation plate 203 contacts the fixing plate 205. Together, the fixing plate 205 can partially block the ventilation plate 203, thus blocking the air holes 204 on the surface of the ventilation plate 203, reducing the airflow and creating different airflow levels at the top and bottom of the ventilation plate 203. This allows for position adjustment and simultaneous adjustment of airflow, improving work efficiency. When the ventilation plate 203 is at the bottom, the cleaning rod 207 is kept at a certain distance from the ventilation plate 203, preventing it from blocking the air holes 204 and ensuring airflow through them. Furthermore, when the ventilation plate 203 is at the bottom, the electric push rod 21... 0. The electric push rod 210 can move the moving rod 211 simultaneously, and the push plate 206 and cleaning rod 207, which are fixedly connected to the moving rod 211, move together. Since the guide rod 212 passes through the push plate 206, the push plate 206 can move along the guide rod 212, so that the push plate 206 and the cleaning rod 207 move in a straight line. At this time, the cleaning rod 207 is aligned with the air hole 204. The movement of the cleaning rod 207 can merge with the air hole 204 to clean the surface of the air hole 204, prevent dust from clogging the air hole 204, ensure use at night, and facilitate subsequent use during the day.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
