Growing vegetables by covering plastic films on greenhouses is to artificially create a suitable ecological environment, adjust the vegetable production season, regulate market demand, promote high-quality and high-yield vegetables, and is one of the effective means to increase farmers' income. Greenhouse planting has certain requirements for internal environmental factors such as temperature and humidity. Therefore, farmers need to roll up or put down the plastic film of the greenhouse according to weather changes to keep the internal environment stable.

This device makes the window open automatically outward through the cooperation of components such as motors, steering gears, rotating shafts, gears, and racks. However, when using this device, multiple columns need to be arranged outside the wall for the installation of components. Therefore, extra space is required during use. At the same time, due to the existence of external columns, the opening degree of the window is limited, affecting the ventilation effect. Content of the Utility Model

Specific embodiments
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] As Figure 1-5 shown, the present utility model provides a technical solution: a ventilation device, which is arranged on the wall 1 of the planting greenhouse, includes a window 2. A ventilation opening is provided on the wall 1, and a frame body is fixedly connected inside the ventilation opening. The window 2 is located inside the frame body. On one side of the wall 1 inside the greenhouse, two slide rails 3 are fixedly connected, and the two slide rails 3 are distributed on the left and right sides of the frame body. Fixed plates 9 are provided on both the left and right sides of the window 2, and the sliders on the two slide rails 3 are fixedly connected to the adjacent fixed plates 9. Lifting mechanisms are provided on both of the two fixed plates 9, and the lifting mechanisms are fixedly connected to the window 2.
[0022] According to the overall structure of the device, a ventilation opening is provided on the wall 1, and a frame body and a window 2 are provided inside the ventilation opening, and the window 2 is located inside the frame body, avoiding occupying the space outside the wall 1. The window 2 can be moved out of the frame body through the lifting mechanism, and then the window 2 can be moved up and down through the slide rail 3, so as to open and close the ventilation opening, facilitating ventilation in the greenhouse, and the window 2 can be moved to different heights according to the ventilation requirements for different degrees of ventilation.
[0023] As Figure 2 shown, support plates 4 are fixedly connected between both of the two slide rails 3 and the wall 1. The cross sections of the two support plates 4 are both U-shaped and are symmetrically arranged.
[0024] The slide rail 3 is supported by the support plate 4, so that there is a certain space between the slide rail 3, the lifting mechanism and the wall 1, facilitating the complete removal of the window 2 from the frame body.
[0025] As Figure 2 shown, screws 12 are movably connected to the inner sides of the support plates 4, and movable blocks 13 are threadedly connected to the screws 12. The movable blocks 13 are fixedly connected to the fixing plates 9, and the screws 12 are drivingly connected to a motor 5.
[0026] The screw 12 is rotated by the motor 5 to move the movable block 13 up and down, thereby driving the window 2 to move, so as to open and close the ventilation opening, facilitating ventilation in the greenhouse.
[0027] Such as Figure 1 , 5 As shown, a motor 5 is fixedly connected to the inner side of the wall 1 below the window 2. Cross universal joints 6 are provided at both the output end of the motor 5 and below the support plate 4. The output shaft of the motor 5 and the bottom end of the screw 12 are respectively fixedly connected to the output ends of the adjacent cross universal joints 6. A transmission shaft 7 is rotatably connected between the cross universal joints 6.
[0028] The screw 12 is rotated by the motor 5 to drive the movable block 13 to drive the window 2 to move. Moreover, the power of the motor 5 is evenly transmitted to the two screws 12 through the cross universal joints 6 and the transmission shaft 7 composed of two meshing bevel gears inside, so that the two screws 12 rotate synchronously, avoiding damage to the window 2 caused by offset when the window 2 moves.
[0029] Such as Figure 2 As shown, the lifting mechanism includes two cylinders 10. The two cylinders 10 are both fixedly connected to the fixing plate 9 and are symmetrically arranged up and down. The telescopic ends of the two cylinders 10 are both fixedly connected with connecting plates 14, and the connecting plates 14 are fixedly connected with the window 2.
[0030] The air pump 8 drives the window 2 to move horizontally, so that the window 2 is moved out of the frame body, facilitating the window 2 to move upward to open the ventilation opening.
[0031] Such as Figure 3 , 4 As shown, a first sealing plate 15 with an L-shaped cross section is fixedly connected to the inner side of the frame body. A U-shaped second sealing plate 11 is fixedly connected to the outer side of the window 2. An airbag 16 is fixedly connected to the inner side of the second sealing plate 11. An air pump 8 is fixedly connected to the window 2, and a trachea penetrating the second sealing plate 11 is fixedly connected between the air pump 8 and the airbag 16.
[0032] When the window 2 is located inside the frame body, a closed space is formed by the first sealing plate 15 and the second sealing plate 11. At this time, the air pump 8 inflates the airbag 16, so that the airbag 16 expands and closely adheres to both the inner sides of the first sealing plate 15 and the second sealing plate 11, thereby sealing the gap between the window 2 and the frame body and avoiding temperature changes caused by air exchange inside and outside the greenhouse.
[0033] A fruit and vegetable planting ecological control device includes the above-mentioned ventilation device.
[0034] Working principle: When in use, the device is connected to an external power supply. When ventilation is required, the cylinder 10 is started, the telescopic end of the cylinder 10 contracts, and the window 2 is driven to move through the connecting plate 14, so that the window 2 is moved out of the frame. Then the motor 5 is started, and the motor 5 drives the transmission shaft 7 to rotate through the cross steering gear 6. The transmission shaft 7 then drives the screws 12 on both sides to rotate through the cross steering gear 6, so that the movable block 13 moves up, thereby driving the window 2 to move up through the fixed plate 9 and the cylinder 10, so as to open the vent for ventilation, and the upward movement of the window 2 can be controlled according to the ventilation needs. The vents are opened to different sizes. When ventilation is not needed, the motor 5 drives the screw 12 to rotate in the opposite direction through the cross-steering gear 6 and the transmission shaft 7 to move the window 2 downward. Then the telescopic rod of the cylinder 10 is extended to move the window 2 back into the frame, thereby closing the vents and blocking ventilation. When the weather temperature is low, the air pump 8 is started. The air pump 8 inflates the air bag 16 through the air pipe to expand the air bag 16. The air bag 16 fits tightly with the first sealing plate 15 and the second sealing plate 11 to seal, thereby avoiding air leakage from the gap between the window 2 and the frame to affect the internal temperature of the greenhouse.
[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
