Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse sunshade, in particular to an electric sunshade device for a greenhouse. Background Art

[0002] Greenhouse, also known as hothouse, is a facility that allows light to pass through and keeps heat (or heats) for growing plants. It requires an electric sunshade device for greenhouses.

[0003] For example, a greenhouse sunshade device with the authorization announcement number "CN 219812689 U" drives the swing arm to swing through the power output end of the reduction motor, thereby using the swing arm to drive the counterweight rod, so that the counterweight rod can move in conjunction with the guide hole set at the guide bracket, and the counterweight rod is limited by a limit block to prevent the counterweight rod from being separated from the guide hole. When the counterweight rod is close to the connecting rod, the sunshade cloth is retracted, and when the counterweight rod is away from the connecting rod, the sunshade cloth is lowered, which can make the sunshade cloth be quickly retracted and extended, thereby improving work efficiency. However, the device drives the counterweight rod to drive the bracket to move through the swing arm, thereby driving the sunshade cloth to shrink. However, since the material of the sunshade cloth is relatively soft, it is easy to deform when shrinking, resulting in shrinkage failure, which reduces the working quality of the device. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the device drives the counterweight rod to move the bracket through the swing arm, thereby driving the sunshade cloth to retract, but since the material of the sunshade cloth is relatively soft, it is easy to deform when the sunshade cloth is retracted, resulting in retraction failure and reducing the working quality of the device. An electric sunshade device for a greenhouse is proposed.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An electric sunshade device for a greenhouse is designed, comprising a base and a frame, wherein the upper end of the base is fixedly connected to the frame, the lower end of the frame is provided with a flip device, the upper end of the frame is provided with a winding device, a sunshade cloth is installed above the frame, the bottom end of the sunshade cloth is fixedly connected to a sliding rod, and the right side of the frame is fixedly connected to a steel frame.

[0007] Preferably, the flipping device includes a first motor and a first shell, the outer wall of the first shell is fixedly connected to the frame, the first motor is fixedly connected to the first shell through a bracket, the output shaft of the first motor is fixedly connected to a worm, the outer wall of the worm is engaged with the worm wheel, the inner wall of the worm wheel is fixedly connected to a first rotating shaft, and the outer wall of the first rotating shaft is fixedly connected to a rotating rod.

[0008] Preferably, both ends of the worm are rotatably connected to the first housing via bearings, the first rotating shaft is rotatably connected to the first housing via bearings, and the inner wall of the right end of the rotating rod is movably connected to the sliding rod.

[0009] Preferably, the inner wall of the steel frame is slidably connected to the slide rod, and the frame is movably connected to the revolving door via a hinge.

[0010] Preferably, the winding device includes a second motor and a second shell, the outer wall of the second shell is fixedly connected to the frame, the second motor is fixedly connected to the second shell through a bracket, the output shaft of the second motor is fixedly connected to a first gear, the outer wall of the first gear is meshed with the second gear, and the inner wall of the second gear is fixedly connected to a second rotating shaft.

[0011] Preferably, the first gear output shaft is rotatably connected to the second housing and the frame respectively through bearings, the second rotating shaft is rotatably connected to the second housing and the frame respectively through bearings, and a sunshade cloth is wrapped around the outer wall of the second rotating shaft.

[0012] The utility model proposes an electric sunshade device for a greenhouse, the beneficial effect of which is that: through the cooperation of the flipping device and the winding device, the rotation of the output shaft of the first motor and the second motor is started at the same time, the output shaft of the first motor is started to rotate to drive the worm gear to rotate. Since the worm gear has the self-locking characteristic, the rotation of the worm gear drives the worm gear to rotate, and the rotation of the worm gear drives the first rotating rod to rotate synchronously. The first rotating rod rotates and the rotating rod rotates. While the rotating rod rotates, it drives the sliding rod to slide inside the steel frame. The output shaft of the second motor rotates and drives the first gear to rotate. Since the number of teeth of the first gear is less than that of the second gear, the rotation of the first gear drives the second gear to rotate slowly, realizing deceleration transmission while increasing torque. When the second gear rotates, it drives the second rotating shaft to rotate. The rotation of the second rotating shaft drives the sunshade cloth to reel up. The sliding rod is driven to move by the rotating rod, and the second rotating shaft drives the sunshade cloth to reel up, making the sunshade cloth more stable during the reeling process, avoiding the reeling failure caused by the relatively soft material of the sunshade cloth causing deformation, and improving the work quality.

[0025] Working principle:

[0026] When shading is needed for a small household greenhouse, the flipping device 2 and the winding device 3 on both sides are controlled to work at the same time, the flipping device 2 drives the slide bar 6 to rotate clockwise, the slide bar 6 slides inside the steel frame 7, and the winding device 3 drives the sunshade cloth 5 to be released, and the frame 4 is covered and shaded with the cooperation of the slide bar 6 and the sunshade cloth 5 to complete the shading process of the greenhouse.

[0027] The rotation process of the slider:

[0028] Connect the external power supply of the first motor 201, start the output shaft of the first motor 201 to rotate and drive the worm 203 to rotate. Since the worm gear has the self-locking characteristic, the rotation of the worm 203 drives the worm wheel 204 to rotate, and the rotation of the worm wheel 204 drives the first rotating rod 205 to rotate synchronously. The first rotating rod 205 rotates the rotating rod 206, and the rotating rod 206 rotates while driving the slide rod 6 to slide inside the steel frame 7, completing the rotation process of the slide rod.

[0029] The rolling process of the sunshade cloth:

[0030] Connect the external power supply of the second motor 301, start the output shaft of the second motor 301 to rotate and drive the first gear 303 to rotate. Since the number of teeth of the first gear 303 is less than the number of teeth of the second gear 304, the rotation of the first gear 303 drives the second gear 304 to rotate slowly, realizing the reduction transmission while increasing the torque. The rotation of the second gear 304 drives the second rotating shaft 305 to rotate at the same time. The rotation of the second rotating shaft 305 drives the sunshade cloth 5 to reel in, completing the reeling process of the sunshade cloth.
