Abstract
Description
Technical Field
[0001] This application relates to the field of agricultural engineering technology, specifically to a device for taking in and releasing insulation blankets for greenhouses. Background Technology
[0002] The greenhouse insulation blanket deployment and retraction device is mainly used to automatically unfold and retract the insulation blanket on the sloping roof of the greenhouse. Through a mechanical transmission structure, it replaces manual operation, thereby regulating the temperature inside the greenhouse. The insulation blanket is used to provide warmth when it is cold, and it is retracted when the temperature is suitable to ensure adequate light, thus improving the convenience and efficiency of greenhouse cultivation.
[0003] However, existing greenhouse insulation blanket retraction devices lack effective protection for the greenhouse roof insulation film when retracting or extending the insulation blanket. The edges of the insulation blanket or the drive components are prone to hard friction with the insulation film, resulting in damage to the film surface and shortening its service life.
[0004] Furthermore, in existing thermal insulation blanket retraction devices, the thermal insulation blanket and protective structure often operate independently. When the thermal insulation blanket is rolled up, the protective structure cannot be rolled up simultaneously, which may block the light of the vegetation inside the greenhouse and affect plant growth. When unfolded, the protective structure and the thermal insulation blanket are not covered in an appropriate order, making it difficult to form effective protection. Utility Model Content
[0005] The purpose of this invention is to provide a device for taking in and taking out insulation blankets for greenhouses, so as to solve the problems mentioned in the background art.
[0006] The technical solution adopted by this application to solve its technical problem is:
[0007] An insulation blanket retraction device for a greenhouse is disclosed. The greenhouse has a sloping roof covered with an insulation film. The device includes a retractable rod, a drive assembly, a rotating arm, and a column. The output end of the drive assembly is keyed to a drive rod. Both ends of the drive rod are fixedly installed to the ends of the retractable rod via flanges. The side wall of the retractable rod is covered with an insulation blanket. One end of the rotating arm is fixedly installed to the drive assembly, and the other end of the rotating arm is hinged to the top of the column. The bottom of the column is buried underground.
[0008] The side wall of the rotating arm is fixedly equipped with a protective component for protecting the insulation film. The protective component includes a fixing frame, a first rotating drum, a second rotating drum, and a connecting mechanism. The top of the fixing frame is fixedly installed on the side wall of the rotating arm. The bottom two ends of the fixing frame are rotatably installed with the side wall of the first rotating drum, respectively. The two ends of the first rotating drum are rotatably installed with the second rotating drum through the connecting mechanism, respectively. The side wall of the first rotating drum is connected to the side wall of the winding rod through a primary transmission mechanism. One end of the first rotating drum and the second rotating drum are connected through a secondary transmission mechanism. The side wall of the second rotating drum is wound up to protect the insulation film.
[0009] Preferably, the drive assembly includes a drive motor and a gearbox. The drive motor is fixedly mounted on the rotating arm, and the output shaft of the drive motor is connected to the input shaft of the gearbox via a belt transmission mechanism. The drive rod is fixedly mounted to the output shaft of the gearbox.
[0010] Preferably, the primary transmission mechanism includes a first sprocket, a second sprocket, and a first chain. The interior of the first sprocket is keyed to the side wall of the drive rod. The first sprocket is connected to the second sprocket via the first chain. The second sprocket is fixedly mounted on the side wall of the first rotating drum.
[0011] Preferably, the secondary transmission mechanism includes a third sprocket, a second chain, and a fourth sprocket. The third sprocket is fixedly installed on the end of the first rotating drum, and the fourth sprocket is fixedly installed on the end of the second rotating drum. The third sprocket is connected to the fourth sprocket via a transmission connection.
[0012] Preferably, the connecting mechanism includes a connecting arm and a sleeve. The two ends of the connecting arm are fixedly connected to the sleeve, and the sleeve is respectively fitted onto the side walls of the first rotating cylinder and the second rotating cylinder. Bearings are installed inside the sleeve, and the two ends of the first rotating cylinder and the second rotating cylinder are rotatably connected in the sleeve.
[0013] Preferably, a mounting plate is fixedly connected to the side wall of the swing arm, and the fixing bracket is fixedly mounted on the mounting plate by screws.
[0014] Preferably, the first and second rotating drums are arranged in parallel.
[0015] The beneficial effects of this application are:
[0016] This technical solution, by setting up protective components and utilizing the linkage structure composed of a fixed frame, a first rotating drum, and a second rotating drum, ensures that the protective blanket always covers the surface of the insulation film during the process of putting the insulation blanket in and taking it out. This avoids direct contact between the edge of the insulation blanket or the driving component and the film surface, which would cause hard friction. Furthermore, with the help of a primary transmission mechanism and a secondary transmission mechanism, the synchronous linkage of the insulation blanket and the protective blanket can be achieved.
[0017] When rolling up, the protective blanket and the insulation blanket are rolled up simultaneously to avoid blocking sunlight from reaching the vegetation inside the greenhouse; when unfolding, the protective blanket is laid before the insulation blanket, with the sides of the insulation blanket covering the bottom of the protective blanket. This ensures the insulation effect and effectively enhances the protection of the insulation film, thereby improving the efficiency and management convenience of the greenhouse.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0040] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.
[0041] Please see Figure 1-4 The embodiments provided by this utility model are as follows:
[0042] like Figure 1 and Figure 2 As shown, a heat insulation blanket retraction device for a greenhouse is disclosed. The top surface of the greenhouse is set as a sloping roof 1, and a heat insulation film is laid on the sloping roof 1. The heat insulation blanket retraction device includes a retracting rod 4, a drive assembly 5, a rotating arm 6, and a column 7. The output end of the drive assembly 5 is keyed to a drive rod 54. Both ends of the drive rod 54 are fixedly installed to the ends of the retracting rod 4 through flanges. The side wall of the retracting rod 4 is covered with a heat insulation blanket 2. One end of the rotating arm 6 is fixedly installed to the drive assembly 5, and the other end of the rotating arm 6 is hinged to the top of the column 7. The bottom of the column 7 is buried underground. The drive assembly 5 includes a drive motor 51 and a gearbox 53. The drive motor 51 is fixedly installed on the rotating arm 6. The output shaft of the drive motor 51 and the input shaft of the gearbox 53 are connected by a belt transmission mechanism 52. The drive rod 54 is fixedly installed to the output shaft of the gearbox 53.
[0043] When the insulation blanket 2 on the inclined roof 1 needs to be unfolded or retracted, the drive motor 51 is powered on and rotates. The power is transmitted to the input shaft of the gearbox 53 through the belt transmission mechanism 52. The gearbox 53 accelerates or decelerates through the gear set (adjusted according to the unfolding or retracting speed requirements of the insulation blanket 2), and then transmits the power to the output shaft. The output power of the drive motor 51 is decelerated and increased in torque by the gearbox 53, which drives the winding rod 4 to rotate in both directions. This allows the insulation blanket 2 rolled up on the side wall of the winding rod 4 to be unfolded or rolled up, realizing the unfolding or retracting of the insulation blanket 2. One end of the rotating arm 6 is fixed to the drive component 5, and the other end is hinged to the column 7, so that the drive system can be adjusted with the angle of the inclined roof 1. The column 7 is buried deep in the ground to provide stable support. The overall structure ensures the power transmission and stability of the unfolding or retracting process of the insulation blanket 2.
[0044] like Figure 1 , Figure 3 and Figure 4As shown, a protective assembly for protecting the insulation film is fixedly installed on the side wall of the rotating arm 6. The protective assembly includes a fixing frame 8, a first rotating cylinder 9, a second rotating cylinder 10, and a connecting mechanism 13. The top of the fixing frame 8 is fixedly installed on the side wall of the rotating arm 6. Specifically, a mounting plate 61 is fixedly connected to the side wall of the rotating arm 6. The fixing frame 8 is fixedly installed on the mounting plate 61 by screws. The fixing frame 8 is fixed to the rotating arm 6 by the mounting plate 61 and screws to ensure structural rigidity and avoid vibration.
[0045] The bottom ends of the fixed frame 8 are rotatably mounted to the side walls of the first rotating cylinder 9. The two ends of the first rotating cylinder 9 are rotatably mounted to the second rotating cylinder 10 through the connecting mechanism 13. The connecting mechanism 13 includes a connecting arm 131 and a sleeve 132. The two ends of the connecting arm 131 are fixedly connected to the sleeve 132. The sleeve 132 is respectively fitted onto the side walls of the first rotating cylinder 9 and the second rotating cylinder 10. Bearings are installed inside the sleeve 132. The two ends of the first rotating cylinder 9 and the second rotating cylinder 10 are rotatably connected in the sleeve 132.
[0046] Among them, the bottom ends of the fixed frame 8 are also fixedly connected with sleeves 132. The fixed frame 8 rotates on the side wall of the first rotating cylinder 9 through the sleeves 132. The sleeves 132 at the bottom of the fixed frame 8 and the first rotating cylinder 9 form a rotating pair, so that the first rotating cylinder 9 can rotate freely, while the bearing reduces the frictional resistance.
[0047] The first rotating drum 9 and the second rotating drum 10 are arranged in parallel. The sleeve 132 is sleeved on both ends of the first rotating drum 9 and the second rotating drum 10 through bearings, so that the two can rotate independently relative to the fixed frame 8, while maintaining a parallel distance through the connecting arm 131.
[0048] When the rotating arm 6 rotates around the column 7, the fixed frame 8 swings synchronously with the rotating arm 6, while the first rotating cylinder 9 and the second rotating cylinder 10 can maintain their relative positions with the roof insulation film due to the rotating connection, avoiding hard friction.
[0049] like Figure 3 As shown, the side wall of the first rotating drum 9 is connected to the side wall of the take-up rod 4 via a primary transmission mechanism 11. The primary transmission mechanism 11 includes a first sprocket 111, a second sprocket 112, and a first chain 113. The interior of the first sprocket 111 is keyed to the side wall of the drive rod 54. The first sprocket 111 is connected to the second sprocket 112 via the first chain 113. The second sprocket 112 is fixedly mounted on the side wall of the first rotating drum 9. When the drive rod 54 rotates, the keyed first sprocket 111 rotates synchronously. Power is transmitted to the second sprocket 112 via the first chain 113, thereby driving the first rotating drum 9 to rotate. This ensures that the rotation speed of the take-up rod 4 and the first rotating drum 9 are synchronized, avoiding damage to the insulation blanket 2 or protective components due to speed differences, and providing power for the take-up and take-up of the protective blanket 3.
[0050] like Figure 4As shown, one end of the first rotating drum 9 and the second rotating drum 10 are connected by a secondary transmission mechanism 12. The side wall of the second rotating drum 10 is rolled up to protect the protective blanket 3 for the insulation film. The secondary transmission mechanism 12 includes a third sprocket 121, a second chain 122 and a fourth sprocket 123. The third sprocket 121 is fixedly installed on the end of the first rotating drum 9 and the fourth sprocket 123 is fixedly installed on the end of the second rotating drum 10. The third sprocket 121 is connected to the fourth sprocket 123 through the fourth sprocket 123.
[0051] When the first rotating drum 9 rotates, the third sprocket 121 at the end drives the fourth sprocket 123 through the second chain 122, causing the second rotating drum 10 to rotate synchronously. When the insulation blanket 2 is rolled up, the second rotating drum 10 simultaneously rolls up the protective blanket 3 so that the protective blanket 3 can also be rolled up, preventing the vegetation under the protective blanket 3 from blocking the sunlight. When the insulation blanket 2 is released, since the second rotating drum 10 is located below the winding rod 4, the insulation blanket 2 can be released first, and then the side of the insulation blanket 2 can cover the lower sides of the protective blanket 3. The protective blanket 3 can prevent the driving component 5 from rubbing against the insulation film, so that the protective blanket 3 always covers the surface of the insulation film and avoids the edge of the insulation blanket 2 from scratching the film surface.
[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
