Description

Technical Field

[0001] This utility model relates to the field of vegetable greenhouse technology, specifically to a vegetable greenhouse ventilation roller shutter assembly. Background Technology

[0002] As an important agricultural facility, vegetable greenhouses create suitable environmental conditions for vegetable growth, greatly improving vegetable yield and quality, and occupying a key position in modern agriculture. In the realization of the many functions of vegetable greenhouses, ventilation roller shutters play a vital role. Ventilation is a key link in maintaining a good growing environment inside the greenhouse, as it can regulate the temperature and humidity inside the greenhouse.

[0003] The utility model patent with announcement number CN217905390U discloses a vegetable planting greenhouse, including a plastic greenhouse. A water collection trough is installed in the center of the interior of the plastic greenhouse. The water collection trough is embedded in the ground. The soil layers on both sides of the water collection trough are inclined, and the inclination direction of the soil layers is downward from the plastic greenhouse towards the water collection trough.

[0004] Although this utility model uses an inclined ground to allow surface water to be filtered through a soil interception net and flow into a water collection trough for collection and treatment, thus avoiding waste of irrigation water, and the height of the soil interception net can be adjusted according to the soil layer by rotating a screw to ensure that the soil interception net always has an interception effect on the soil layer, and the soil interception net can be removed by pulling out a telescopic plate for easy cleaning, it has some drawbacks. Ventilation adjustment is often inconvenient, often requiring manual winding and unwinding, which is not only labor-intensive and time-consuming, but also unable to respond promptly to sudden weather changes, making it difficult to quickly adjust the ventilation status and affecting the stability of the vegetable growing environment. Utility Model Content

[0005] The purpose of this utility model is to provide a ventilation roller shutter assembly for vegetable greenhouses to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A ventilation roller shutter assembly for a vegetable greenhouse includes a ground surface on which several sets of greenhouse supports are regularly fixed. The assembly also includes several ventilation roller shutter assemblies, each mounted on one of the sets of greenhouse supports. Each ventilation roller shutter assembly includes a guide rail and two movable plates. The guide rail is fixed to the top surface of the middle greenhouse support in each set. Both movable plates are slidably connected to the guide rail. An mounting plate is fixed between the top ends of the two movable plates.

[0008] Preferably, the ventilated roller shutter assembly further includes a plurality of gear teeth, which are fixed to the top surface of the guide rail;

[0009] Preferably, a rotating shaft is rotatably connected between the two movable plates, and a drive gear is fixed to the outer wall of the rotating shaft, the drive gear meshing with the gear teeth;

[0010] Preferably, sliders are fixed at the bottom of the opposite surfaces of the two movable plates, and grooves corresponding to the positions and sizes of the sliders are opened on both the front and rear sides of the guide rail.

[0011] Preferably, a motor is fixed to the top surface of the mounting plate, and the output shaft of the motor is connected to the rotating shaft via a belt drive.

[0012] These four settings, through the configuration of gear teeth, drive gears, sliders and grooves, and motor transmission, make the movement of the ventilation roller shutter assembly more stable, precise, convenient and automated, saving manpower and improving the timeliness of adjustment, and preventing the ventilation roller shutter assembly from obstructing the greenhouse support when not in use.

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Please see Figures 1-5 The present invention provides the following technical solution:

[0030] A greenhouse ventilation roller shutter assembly includes a ground 100 on which several sets of greenhouse supports 200 are regularly fixed. It also includes several ventilation roller shutter assemblies 300, each mounted on a set of greenhouse supports 200. Each ventilation roller shutter assembly 300 includes a guide rail 301 and two movable plates 303. The guide rail 301 is fixed to the top surface of the middle greenhouse support 200 in each set. Both movable plates 303 are slidably connected to the guide rail 301. An mounting plate 307 is fixed between the top ends of the two movable plates 303. A rotating rod 310 is rotatably connected to each of the two movable plates 303. A winding roller 313 is fixed to both ends of the rotating rod 310. The winding roller 313 is used to wind up the covering film. The ventilation roller shutter assembly 300 includes two movable plates 303 slidably connected to the guide rail 301. The top of the movable plate 303 is fixedly mounted with a plate 307, and the movable plate 303 is rotatably connected to a rotating rod 310 with a winding roller 313, so that the vegetable greenhouse has a ventilated roller curtain structure that can be flexibly rolled up and rolled up. This allows for easy adjustment of the ventilation in the greenhouse by rolling up and unfolding the film, meeting the needs of different ventilation conditions during vegetable growth.

[0031] In this embodiment, please refer to Figures 1-5 The ventilation roller shutter assembly 300 also includes several gear teeth 302, which are fixed on the top surface of the guide rail 301. By fixing several gear teeth 302 on the top surface of the guide rail 301, a basic structure is provided for subsequent cooperation with the drive gear 306. The setting of the gear teeth 302 makes the ventilation roller shutter assembly 300 have a more stable transmission structure during movement, which can more accurately control the movement position of the ventilation roller shutter assembly 300, and thus more accurately adjust the ventilation volume of the greenhouse.

[0032] A rotating shaft 305 is rotatably connected between the two movable plates 303. A drive gear 306 is fixed on the outer wall of the rotating shaft 305. The drive gear 306 meshes with the gear teeth 302. When the rotating shaft 305 rotates, the drive gear 306 rolls on the gear teeth 302, causing the movable plates 303 to slide along the guide rail 301. This structure makes the movement of the ventilation roller shutter assembly 300 more convenient and labor-saving, while improving the stability and reliability of the movement of the ventilation roller shutter assembly 300.

[0033] Slider 304 is fixed at the bottom of the opposite side of the two movable plates 303. The front and rear sides of the guide rail 301 are provided with grooves that correspond to the position and size of the slider 304. The cooperation between the slider 304 and the groove further restricts the movement trajectory of the movable plate 303, so that the movable plate 303 can only slide along the guide rail 301. This avoids the movable plate 303 from shaking or deviating during movement, enhances the overall stability of the ventilation roller shutter assembly 300, and ensures the smooth operation of rolling up and unfolding the film covering.

[0034] A motor 308 is fixed on the top surface of the mounting plate 307. The output shaft of the motor 308 is connected to the rotating shaft 305 via a belt 309. The motor 308 serves as a power source, driving the rotating shaft 305 to rotate via the belt 309, which in turn drives the drive gear 306 to move, thereby realizing the movement of the ventilation roller shutter assembly 300. This setup enables the automated operation of the ventilation roller shutter assembly 300, which is more efficient and convenient than manual operation, saves labor costs, and improves the timeliness of greenhouse ventilation adjustment.

[0035] In this embodiment, please refer to Figures 1-5 The output shaft of motor 308 is coaxially connected to a drive gear 311, and the rotating rod 310 is coaxially connected to a driven gear 312. The drive gear 311 and the driven gear 312 mesh with each other. When motor 308 is working, the drive gear 311 and the driven gear 312 mesh with each other to drive the rotating rod 310 to rotate, so that the take-up roller 313 can synchronously perform the action of winding or unfolding the film. This ensures the stability of power transmission of the take-up roller 313 during the winding and unfolding of the film, and ensures that the film can be wound or unfolded evenly, avoiding problems such as uneven film wrapping.

[0036] Both take-up rollers 313 extend to the edge of each set of greenhouse supports 200. A support plate 314 is fixed on the top surface of each set of greenhouse supports 200. The support plate 314 is used to assist in supporting the take-up rollers 313. The setting of the support plate 314 distributes part of the weight of the take-up rollers 313, reduces the load pressure on the moving plate 303 and the rotating rod 310, extends the service life of the relevant components of the ventilation roller curtain assembly 300, and makes the take-up rollers 313 more stable during rotation, which is conducive to improving the quality of film covering, winding and unfolding.

[0037] Each of the two take-up rollers 313 has a limit wheel 315 fixed at one of its opposite ends. The support plate 314 has a through groove that corresponds to the position and size of the limit wheel 315. The cooperation between the limit wheel 315 and the through groove restricts the axial displacement of the take-up roller 313 during rotation, prevents the take-up roller 313 from axially moving during rotation, ensures the stability of the take-up roller 313 during the winding and unfolding of the film covering process, further improves the winding and unfolding effect of the film covering, and ensures that the greenhouse ventilation roller curtain assembly 300 can operate stably for a long time.

[0038] Finally, it should be noted that the motor 308 involved in this utility model is a general standard part or a component known to those skilled in the art. Its structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0039] When the vegetable greenhouse ventilation roller shutter assembly of this utility model is in use, the motor 308 starts when the covering film is unfolded, and drives the rotating shaft 305 to rotate through the belt 309, which drives the gear 306 to roll on the gear teeth 302, so that the moving plate 303 moves along the guide rail 301. At the same time, the driving gear 311 drives the driven gear 312 to rotate, driving the winding roller 313 to release the covering film to cover the greenhouse.

[0040] During the winding and film covering process, the motor 308 reverses, the moving plate 303 moves in the opposite direction, and the winding roller 313 synchronously winds up and covers the film until it reaches the ground 100, achieving an unobstructed state.

[0041] The slider 304 slides in the groove to limit the movement of the moving plate 303, and the limit wheel 315 prevents the winding roller 313 from moving axially, thus ensuring the stability of the system operation.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
