Technical Field

[0001] The utility model relates to the technical field of agricultural facilities, in particular to a temperature control and heat preservation curtain device for a greenhouse. Background Technique

[0002] In modern agriculture, as an important facility for controlling the growth environment of crops, the stability of the internal environment of a greenhouse directly affects the growth rate and quality of crops. Especially in cold or areas with large temperature differences, the temperature control and heat preservation functions of greenhouses are particularly important. As an important part of the temperature control system of greenhouses, heat preservation curtains can not only effectively isolate the external low temperature and reduce heat loss, but also adjust the light and temperature in the greenhouse to a certain extent, providing a suitable growth environment for crops. Due to the complex internal environment of greenhouses, with large changes in temperature and humidity, heat preservation curtains are prone to accumulate dust and dirt, affecting the light transmittance and heat preservation effect. It is necessary to regularly disassemble and clean the curtains. The existing curtains usually have a relatively complex structure, are difficult to disassemble and clean, time-consuming and laborious, resulting in the cleaning work being difficult to be effectively carried out, thus affecting the overall operation efficiency of greenhouses.

[0003] Therefore, there is now developed a temperature control and heat preservation curtain device for a greenhouse that can facilitate the disassembly, cleaning and installation of the curtain, reduce the labor intensity of workers, and improve the cleaning efficiency of the curtain. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following describes the present utility model in detail with reference to the accompanying drawings and specific embodiments, but it is not intended to limit the present utility model.

[0020] A greenhouse temperature control and heat preservation curtain device, as Figures 1-6 shown, includes a greenhouse 1, opening and closing doors 2, support frames 3, a motor 4, connecting rods 5, a first rotating shaft 6 and a curtain 7, a limiting frame 8 and a telescopic spring 9, a transmission assembly 10, a second rotating shaft 11, a winding wheel 12, a pulling rope 13, a nut 14 and a screw rod 15. Two front and rear opening and closing doors 2 are rotatably connected to both the front and rear sides of the greenhouse 1. Two front and rear support frames 3 are connected to the upper right side of the greenhouse 1. Positioning grooves are provided on the support frames 3 to facilitate the clamping of the connecting rod 5. A motor 4 is connected to the front support frame 3. A connecting rod 5 is connected to the output shaft of the motor 4. A first rotating shaft 6 is rotatably clamped between the support frames 3. The first rotating shaft 6 is clamped with the connecting rod 5. A curtain 7 is wound around the first rotating shaft 6. A limiting frame 8 is slidably connected between the right sides of the support frames 3. Telescopic springs 9 are connected between the support frames 3 and the limiting frame 8. The limiting frame 8 contacts the first rotating shaft 6. A pull rod is provided on the limiting frame 8 for easy pulling. A second rotating shaft 11 is rotatably connected to the upper left part of the greenhouse 1. A transmission assembly 10 is connected between the second rotating shaft 11 and the connecting rod 5. A winding wheel 12 is connected to the middle of the second rotating shaft 11. A pulling rope 13 is wound around the winding wheel 12. The end of the pulling rope 13 is connected to a nut 14. A screw rod 15 is connected to the curtain 7. The screw rod 15 is threadedly connected to the nut 14. The transmission assembly 10 is composed of a belt and belt pulleys. Belt pulleys are provided on the connecting rod 5 and the second rotating shaft 11, and a belt is wound around the belt pulleys.

[0021] When using this device, first move this device to the erection area of the greenhouse 1. By rotating to open the opening and closing door 2, it is convenient to enter and exit the greenhouse 1. When it is necessary to use the curtain 7 to shade the greenhouse 1, start the motor 4 on the support frame 3, so that the connecting rod 5 rotates, driving the first rotating shaft 6 to rotate, so that the curtain 7 unfolds on the first rotating shaft 6. While the connecting rod 5 rotates, through the rotation of the belt and flat belt in the transmission assembly 10, the second rotating shaft 11 rotates, so that the winding wheel 12 rotates, so that the pulling rope 13 is wound up on the winding wheel 12, so that the pulling rope 13 pulls the unfolded curtain 7 to be laid flat on the greenhouse 1, so that the curtain 7 shades the greenhouse 1. By adjusting the shading area of the curtain 7, the temperature in the greenhouse 1 can be controlled, so that the temperature in the greenhouse 1 is controlled within a suitable range. The limiting frame 8 can limit the first rotating shaft 6 to prevent the first rotating shaft 6 from jumping when rotating, so that the first rotating shaft 6 can rotate smoothly. When it is necessary to remove the curtain 7 for cleaning, start the motor 4 so that the curtain 7 is wound up on the first rotating shaft 6, then unscrew the nut 14 from the screw rod 15, and then pull the limiting frame 8 to slide outwards. The telescopic spring 9 is squeezed and contracted, and then the first rotating shaft 6 is removed from the connecting rod 5, so as to take out the curtain 7 for cleaning. After the cleaning is completed, reconnect the first rotating shaft 6 with the connecting rod 5, loosen the limiting frame 8, and the telescopic spring 9 rebounds, driving the limiting frame 8 to re-position and limit the first rotating shaft 6. Then reconnect the nut 14 and the screw rod 15 to complete the cleaning process, thus playing the role of being able to facilitate the disassembly, cleaning and installation of the curtain 7, reducing the labor intensity of the staff, and improving the cleaning efficiency of the curtain 7.
