[0002] The top height adjusting device for a greenhouse is an agricultural mechanical device aiming to improve the controllability of the internal environment of the greenhouse. It allows the operator to adjust the top height of the greenhouse according to the growth stage of the crops, climatic conditions or other agricultural production requirements. Such a design can optimize the lighting, temperature and ventilation conditions, thus promoting the healthy growth of crops and improving the yield and quality. Summary of the Invention

[0003] To solve the above technical problems, the utility model provides a top height adjusting device for a greenhouse.

[0004] The utility model is realized by adopting the following technical scheme: A top height adjusting device for a greenhouse, including a greenhouse main frame. Both the front end and the rear end of the greenhouse main frame are fixedly connected with several first reinforcing ribs. Both sides of the greenhouse main frame are fixedly connected with several second reinforcing ribs. The middle part of the inner wall of the greenhouse main frame is fixedly connected with a bottom fixing plate. Both sides of the upper surface of the bottom fixing plate are fixedly connected with lifting rods.

[0005] Through the above technical scheme, the greenhouse main frame provides the main supporting structure of the greenhouse, ensuring the overall stability and load-bearing capacity of the greenhouse, which is crucial for withstanding extreme weather such as wind and snow in the natural environment. The first reinforcing ribs and the second reinforcing ribs improve the overall stability of the greenhouse by increasing the lateral and longitudinal stiffness of the frame, reducing the structural deformation caused by wind force or uneven distribution of the weight of the internal crops. The bottom fixing plate fixes the greenhouse main frame on the ground, providing additional stability and preventing the greenhouse from shifting or collapsing under external forces. The lifting rods allow the operator to adjust the top height of the greenhouse, which is very useful for creating a suitable microclimate environment, especially at different growth stages of the crops when different space heights are required.

[0006] As a further improvement of the above scheme, both ends of the lifting rod are fixedly connected with connecting plates, and the top of the connecting plate is fixedly connected with a top fixing plate.

[0007] Through the above technical scheme, the connecting plates strengthen the fixation between the lifting rods and the top fixing plate, and the top fixing plate is connected with the bow-shaped frame, facilitating the height adjustment of the greenhouse top.

[0008] As a further improvement of the above scheme, both sides of the front end and the rear end of the greenhouse main frame are fixedly connected with connecting rods, and the inner wall of the connecting rod is provided with a chute.

[0009] Through the above technical solution, the lifting of the heightening frame is facilitated by the connecting rod and the sliding groove, and it is limited to avoid deviation during the height adjustment process.

[0010] As a further improvement of the above solution, the inner wall of the sliding groove is slidably connected with a heightening frame, and several heightening frame reinforcing ribs are fixedly connected to the inner wall of the heightening frame.

[0011] Through the above technical solution, the movement of the heightening frame through the sliding groove provides a mechanical advantage for adjusting the height of the greenhouse, while the heightening frame reinforcing ribs enhance its structural strength to ensure safety during the adjustment process.

[0012] As a further improvement of the above solution, an arch frame is fixedly connected to the top of the heightening frame, arch frame reinforcing ribs are fixedly connected to the inner wall of the arch frame, and the arch frame is connected to the top fixing plate.

[0013] Through the above technical solution, the design of the arch frame helps to disperse the top load, reduce the pressure on the main frame of the greenhouse, and at the same time promote the natural sliding of rainwater and snow, reducing the risk of structural damage.

[0014] As a further improvement of the above solution, a greenhouse door is fixedly connected to the middle of one side of the main greenhouse frame.

[0015] Through the above technical solution, the design of the greenhouse door provides a convenient access passage, facilitating the entry and exit of personnel and equipment, while maintaining the control of the internal environment of the greenhouse.

[0016] As a further improvement of the above solution, outer covering films are fixedly connected to the outer surfaces of the main greenhouse frame and the heightening frame, a top covering film is fixedly connected to the top of the arch frame, and top baffles are fixedly connected to both sides of the arch frame.

[0017] Through the above technical solution, these covering components protect the crops from the influence of adverse external climate conditions, and at the same time create an optimal growth environment by adjusting light and temperature.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] The utility model allows the operator to adjust the top height of the greenhouse according to the growth needs of crops by setting multiple structural component devices, optimizing the lighting and ventilation conditions, thereby creating a more suitable microclimate environment. By means of the first reinforcing rib and the second reinforcing rib, the transverse and longitudinal stiffness of the frame is increased, the overall stability of the greenhouse is improved, and the structural deformation caused by wind force or uneven distribution of the weight of internal crops is reduced. The design of the bow-shaped frame helps to disperse the top load, reduce the pressure on the main frame of the greenhouse, and at the same time promote the natural sliding of rainwater and snow, reducing the risk of structural damage. The top height adjustment device of the greenhouse can effectively control the internal environment, meet the growth needs of crops, and improve the crop yield and quality.
