[0029] like Figure 1-Figure 5 As shown, a film greenhouse comprises a support frame 1, on which a plurality of arched beams 2 are arranged and installed, a cross beam 3 is arranged between the tops of two adjacent arched beams 2, and ventilation mechanisms 4 are respectively hingedly connected on both sides of the cross beam 3, and the ventilation mechanism 4 is covered with a first film. By hingedly connecting the ventilation mechanisms 4 on both sides of the cross beam 3, the film greenhouse can be ventilated on one side according to the real-time wind direction, or both sides can be ventilated at the same time to enhance the ventilation effect of the greenhouse, and one end of the ventilation mechanism 4 away from the cross beam 3 is respectively against the first film fixing rod 5, a water guide trough 6 is installed at the connection between the arched beam 2 and the support frame 1, a second film fixing rod 7 is installed in the water guide trough 6, and a second film fixing rod 7 is arranged between the first film fixing rod 5 and the second film fixing rod 7. The film is extended into the water channel 6 through the second film fixing rod 7, so that the water droplets condensed on the inner surface of the second film can directly slide into the water channel 6, avoiding the water droplets on the film from falling into the crops or soil, causing diseases. At least two third film fixing rods 8 are arranged around the support frame 1, and a third film is arranged between the third film fixing rods 8. By arranging the first film, the second film and the third film instead of the traditional glass structure, the cost is reduced and the load-bearing capacity of the film greenhouse is reduced. An automatically retractable shading mechanism 9 is also provided on the support frame 1 and at the bottom of the arched beam 2. The shading mechanism 9 can shade the crops in the greenhouse to ensure that the crops can grow normally in the hot summer.

[0030] like Figure 1 As shown, the support frame 1 includes a plurality of support columns 101, and the third film fixing rod 8 is arranged along the vertical direction of the support column 101. A support rod 102 is provided between the two support columns 101 at the bottom of the arched beam 2. A reinforcing rod 103 is connected between the support rod 102 and the arched beam 2 and the cross beam 3.

[0031] like Figure 1-Figure 3 As shown, the sunshade mechanism 9 includes two sets of brackets 901 arranged opposite to each other, the two sets of brackets 901 are respectively installed at both ends of the support rod 102, and a plurality of first connecting ropes 902 are arranged between the two sets of brackets 901;

[0032] A number of rollers 903 are rotatably installed on each group of brackets 901, and a synchronous transmission belt 905 driven by a first motor 904 is sleeved between the rollers 903. Fixed blocks 906 are relatively installed on the two synchronous transmission belts 905, and a second connecting rope 907 is fixedly installed between the two fixed blocks 906. A sunshade net 908 is arranged between the second connecting rope 907 and the first connecting rope 902. The synchronous transmission belt 905 is driven to move synchronously by the first motor 904. During the movement of the synchronous transmission belt 905, the fixed block 906 and the second connecting rope 907 are driven to move synchronously, so that the second connecting rope 907 is moved away from or close to the first connecting rope 902, thereby driving the sunshade net 908 to expand or contract synchronously, thereby realizing an automatic shading function.

[0033] In this embodiment, the first motor 904 is installed at one end of the film greenhouse, and the output shaft of the first motor 904 is connected to the transmission shaft. The transmission shaft passes through two rollers 903 arranged opposite to each other on the two sets of brackets 901, and drives the synchronous transmission belt 905 to rotate synchronously through the two rollers 903.

[0034] In addition, a support member is provided at the bottom of the sunshade net 908 and between two adjacent support rods 102 to prevent the sunshade net 908 from collapsing. The support member may be a rod-type structure or a rope-type structure.

[0035] like Figure 2-Figure 3 As shown, each bracket group 901 includes a plurality of plates, which are arranged and installed at the ends of the support rod 102, and the roller 903 is rotatably installed on the plates through the support shaft, and the first connecting rope 902 is fixed between two opposite plates at both ends of the support rod 102.

[0036] like Figure 1 and Figure 4 As shown, the ventilation mechanism 4 includes a ventilation frame 401, a first film covers the ventilation frame 401, one end of the ventilation frame 401 is hingedly mounted on the cross beam 3, and the other end rests on the first film fixing rod 5. The ventilation frame 401 is also hingedly connected to the end of the first film fixing rod 5 close to the first film fixing rod 5 with a rack 402, the rack 402 is movably mounted on the gear frame 403, and is meshed with the gear provided on the gear frame 403 for transmission, the gear frame 403 is mounted on a driving rod 405 driven by a second motor 404, the driving rod 405 is rotatably mounted on the bottom of the arched beam 2, specifically, the driving rod 405 is rotatably mounted on a connecting plate, and the connecting plate is fixedly mounted on the arched beam 2, the driving rod 405 is driven to rotate by the second motor 404, the driving rod 405 drives the gear provided on the gear frame 403 to rotate synchronously, and the gear drives the rack 402 to move upward through meshing to open the ventilation frame 401, or moves downward to close the ventilation frame 401.

[0037] like Figure 1 and Figure 4As shown, the ventilation rack 401 includes a number of connecting rods 4011 connected in sequence, and the several connecting rods 4011 together form a rectangular frame structure, the fourth film fixing rods 4012 are respectively installed on the several connecting rods 4011, and the fifth film fixing rod 10 is installed on the crossbeam 3. The first film is arranged between the fourth film fixing rod 4012 and the fifth film fixing rod 10. By arranging the fourth film fixing rod 4012 and the fifth film fixing rod 10, it is convenient to fix the film, and the fixing is convenient and the installation is convenient.

[0038] like Figure 5 As shown, the first film fixing rod 5, the second film fixing rod 7, the third film fixing rod 8, the fourth film fixing rod 4012 and the fifth film fixing rod 10 all include a rod body 11, and a groove 12 is provided on the rod body 11. The first film, the second film and the third film are all pressed in the groove 12 by a clamping member 13. In this embodiment, the opening end of the groove 12 is smaller than the inner cavity of the groove 12. The clamping member 13 is made of an elastic plastic part or a spring, which is convenient for clamping the film in the groove 12 and is not easy to damage the film. The installation is convenient and quick, and the assembly efficiency is high.

[0039] For ease of understanding, the working process of this embodiment is given below:

[0040] like Figure 1-Figure 5 As shown, when ventilation is needed, the second motor 404 drives the driving rod 405 to rotate. During the rotation of the driving rod 405, the gear on the gear frame 403 is driven to rotate synchronously. The gear is meshed with the rack 402 for transmission, and drives the rack 402 to move upward. During the movement, the rack 402 pushes the ventilation frame 401 to rotate upward around the cross beam 3, thereby realizing ventilation of the film greenhouse. Since the two sides of the cross beam 3 are respectively hingedly connected with the ventilation mechanism 4, the film greenhouse can be ventilated on one side or on both sides, which is convenient and has a good ventilation effect. The second motor 404 rotates in the opposite direction, which will drive the ventilation frame 401 to rotate downward, thereby realizing the closure of the film greenhouse.

[0041] When shading is needed, the first motor 904 drives the two synchronous transmission belts 905 to move synchronously, and then drives the fixed blocks 906 on the two synchronous transmission belts 905 to move synchronously, so that the second connecting rope 907 set between the two fixed blocks 906 also moves synchronously. Since the first connecting rope 902 is fixed on the bracket 901 and will not move, during the movement of the second connecting rope 907, it will drive one end of the sunshade net 908 to move away from the first connecting rope 902, thereby realizing shading for crops in the film greenhouse. When the first motor 904 rotates in the opposite direction, the second connecting rope 907 moves toward the direction close to the first connecting rope 902, thereby realizing the contraction of the sunshade net 908.

[0042] In summary, the utility model provides a film greenhouse, which reduces costs by adopting film instead of traditional glass, and at the same time can achieve ventilation on both sides and automatic shading, with a compact structure and easy assembly.

[0043] It should be understood that the purpose of these embodiments is only to illustrate the utility model and is not intended to limit the protection scope of the utility model. In addition, it should also be understood that after reading the technical content of the utility model, those skilled in the art can make various changes, modifications and / or variations to the utility model, and all of these equivalent forms also fall within the protection scope defined by the claims attached to this application.
