The supporting main body 1 is integrally lifted, so that the functions of automatic ventilation and cooling can be realized in the greenhouse without systems such as ventilation and cooling, and the cultivation conditions of fruits and vegetables are improved to a certain extent.

Further, the driving mechanism 5 comprises a connecting seat 51 and a connecting beam 107, the connecting seat 51 is mounted above the cross beam 102, a push-out hydraulic cylinder 52 is hinged on the connecting seat 51, a connecting head 53 is mounted at the head of a piston rod of the push-out hydraulic cylinder 52, and the connecting head 53 penetrates through the connecting beam 107 and is connected with the connecting beam 107;

the driving mechanism 5 further comprises a first connecting rod 55 and a second connecting rod 56 which form a scissor mechanism, the upper ends of the first connecting rod 55 and the second connecting rod 56 are connected with the folding fan 3, a connecting end 57 is formed at the contact position of the first connecting rod 55 and the second connecting rod 56, the connecting beam 107 penetrates through the connecting end 57, a sliding rail 54 is arranged on the arc-shaped supporting beam 101, one end of the second connecting rod 56, which is far away from the connecting end 57, is provided with a roller 561 matched with the sliding rail 54, one end of the first connecting rod 55, which is far away from the connecting end 57, is provided with an extending mounting rod 551, and the extending mounting rod 551 is fixed on the arc-shaped supporting beam 101;

the piston rod of the pushing hydraulic cylinder 52 extends to push the connecting beam 107 to move, and the roller 561 is moved along the length direction of the slide rail 54.

The first connecting rod 55 and the second connecting rod 56 form a scissor mechanism, the folding fan 3 is mounted on the upper surfaces of the first connecting rod 55 and the second connecting rod 56, in the extending process of the piston rod of the pushing hydraulic cylinder 52, the connecting beam 107 is driven to move through the connecting head 53, the connecting end 57 is driven to move in the moving process of the connecting beam 107, and as the connecting end 57 is the intersection point of the first connecting rod 55 and the second connecting rod 56 (according to the principle of the conventional scissor mechanism, when the pushing hydraulic cylinder 52 extends to do work, the roller 561 will finally move along the length direction of the sliding rail 54), when the connecting end 57 starts to move, the folding fan 3 fixed on the first connecting rod 55 and the second connecting rod 56 will be folded.

The folding fan 3 is divided into two parts according to its state:

A. when the open structure on the ceiling 2 is exposed, namely illumination is needed at the moment, the folding fan 3 is in a retraction state under the action of the driving mechanism 5, the piston rod of the pushing hydraulic cylinder 52 is at the minimum extension, the included angle between the first connecting rod 55 and the second connecting rod 56 is approximately overlapped and is close to the position extending into the mounting rod 551, the open structure is exposed, sunlight can be directly irradiated into the greenhouse, and therefore the fruits and vegetables can be illuminated for enough time;

B. when open structure is covered by folding fan 3 on ceiling 2, do not need illumination this moment, folding fan 3 will be in the state of expanding under actuating mechanism 5's effect this moment, it is located the maximum extension to release pneumatic cylinder 52 piston rod this moment, the state of first connecting rod 55 and second connecting rod 56 is as shown in fig. 2 this moment, contained angle between the two is close to 180, and gyro wheel 561 is close to the foremost of slide rail 54 this moment, open structure is covered by folding fan 3, sunshine can't penetrate into in the big-arch shelter, avoid making the too high fruit vegetables growth situation and quality reduction of temperature in the big-arch shelter because of the illumination of longer time.

The slide rail 54 is rectangular and forms an angle with the ground.

As an alternative embodiment of the slide rail 54, the slide rail 54 is preferably arranged linearly, and the situation when the roller 561 moves along the slide rail 54 during the extension of the pushing hydraulic cylinder 52 is complicated (during the extension of the pushing hydraulic cylinder 52, it is hinged to the connecting seat 51, during the extension of the pushing hydraulic cylinder 52, there is a displacement of the connecting beam 107 in the vertical direction, and the pushing hydraulic cylinder 52 also rotates around the pin on the connecting seat 51, if the slide rail 54 adopts a non-linear structure, it may make the movement complicated), also, as an alternative embodiment to the push-out cylinder 52, the push-out cylinder 52 may be an electric push rod, when the push-out cylinder 52 employs an electric push rod, the controller may control the extension of the push-out cylinder 52, the amount of extension affects the positional relationship between the first link 55 and the second link 56, and ultimately represents the opening/closing degree (opening degree) of the folding fan 3. If the push-out hydraulic cylinder 52 adopts an electric push rod, the advantages compared with the adoption of a hydraulic cylinder are that: the hydraulic cylinder can be stopped only at the two limit positions of opening and closing, and if the hydraulic cylinder is stopped between the two limit positions of opening and closing, redundant control devices are required to be added to realize closed-loop control of the extension amount of the pushing hydraulic cylinder 52.

The limiting roller 1032 is matched with a limiting groove 1041 formed in the bearing support 104, so that the bearing support 104 has a certain guiding function relative to the leg beam 103 in the process that the lifting hydraulic cylinder 105 pushes the supporting main body 1 to move upwards integrally, and the supporting main body 1 can move in a direction parallel to the limiting groove 1041 in the process of moving upwards.

The inside of fly net 4 still is equipped with temperature and humidity sensor, temperature and humidity sensor and controller electric connection.

The insect-proof net 4 is a net structure with certain density, and the insect-proof net 4 can be used for preventing insects, flies and the like from entering the greenhouse and causing bad influence on the growth of fruits and vegetables. Install temperature and humidity sensor additional in the fly net 4, the temperature: may be transferred to a controller which in turn controls the elevation of the supporting body 1 or the opening degree of the folding fan 3. Humidity: the water yield of the irrigation equipment can be adjusted. Finally, the fruits and vegetables cultured in the greenhouse are in a better growth condition, and the growth of the fruits and vegetables is facilitated.
