Description

Technical Field

[0001] This utility model relates to the technical field of greenhouse auxiliary facilities, specifically a greenhouse roller shutter device with snow-proof function. Background Technology

[0002] Greenhouse curtain rolling machines are devices used to control the rolling up and down of greenhouse insulation blankets or straw curtains. They mainly serve to keep the greenhouse warm at night or in winter. In winter, snow accumulation is inevitable. Snow accumulation can make the curtain too heavy, causing the motor to overload. If the snow is not cleared in time, it can also freeze after melting, affecting the rolling up and down. Currently, for curtain rolling machines without snow removal mechanisms, farmers need to manually clear the snow after it falls, which is labor-intensive and difficult. Some curtain rolling machines with snow removal mechanisms on the market have complex structures, high maintenance costs, and are expensive, which is too costly and puts a heavy economic burden on farmers. Therefore, a snow removal structure based on the most widely used bracket-type curtain rolling machine is proposed. Utility Model Content

[0003] To address the above technical problems, this utility model provides a greenhouse roller shutter device with snow-proof function.

[0004] To solve the above-mentioned technical problems, the present invention provides a greenhouse roller shutter device with snow-proof function, comprising a greenhouse, a side wall ladder and an annex fixedly connected to one side of the greenhouse, a walkway for people to walk on the top of the rear wall of the greenhouse, an insulation curtain covering the greenhouse, one end of the insulation curtain being fixedly connected to the top of the greenhouse, the insulation curtain being broken in the middle vertically, a two-section bracket hinged to the front of the greenhouse, the two sections of the bracket being hinged together, a machine head hinged to the other end of the bracket, and a first double-output shaft motor and a second... The system includes a dual-output shaft motor and a third dual-output shaft motor. The first dual-output shaft motor is located between the second and third dual-output shaft motors. The output end of the first dual-output shaft motor is fixedly connected to a roller shutter roller. The other end of the insulation curtain is fixedly connected to the roller shutter roller. The output end of the second dual-output shaft motor is fixedly connected to an upper cleaning roller. The output end of the third dual-output shaft motor is fixedly connected to a lower cleaning roller. Rollers are connected to both ends of the roller shutter roller, the upper cleaning roller, and the lower cleaning roller. A baffle is provided between the upper cleaning roller and the roller shutter roller. One side of the baffle is fixedly connected to the machine head.

[0005] Furthermore, both ends of the upper and lower cleaning rollers are connected to the roller shutter roller via connecting plates, and the other side of the baffle is fixedly connected to the connecting plate.

[0007] Furthermore, a controller is fixedly connected to the lower part of the bracket, and the first dual-output shaft motor, the second dual-output shaft motor, and the third dual-output shaft motor are all controlled by the controller.

[0008] This utility model has the following advantages compared with the prior art:

[0009] 1. This utility model uses an upper cleaning roller to rotate and lift snow from the insulation curtain, and a baffle to slide the snow onto the greenhouse film. Then, as the machine head moves downwards, the lower cleaning roller removes the snow. This utility model has a simple structure, is easy to maintain, and has low cost. This device can clean snowfall during the day when the insulation curtain is raised, and at night when the insulation curtain is lowered, making it highly practical. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figures 1 to 5The greenhouse curtain device shown includes a greenhouse 1, with a side wall ladder 101 and an annulus 102 fixedly connected to one side of the greenhouse 1. The annulus 102 is used to house the control system inside the greenhouse, such as temperature control devices and humidity control devices, and can also be used to temporarily store vegetables. A walkway is provided on the top of the rear wall 103 of greenhouse 1. Greenhouse 1 is covered with an insulation curtain 10. One end of the insulation curtain 10 is fixedly connected to the top of greenhouse 1. The insulation curtain 10 is vertically broken in the middle to facilitate the movement of the machine head 3 without obstructing its movement. A two-section support 2 is hinged to the front of greenhouse 1. The two ends of the support 2 are hinged together, and the other end of the support 2 is hinged to the machine head 3. A first dual-shaft motor 301, a second dual-shaft motor 302, and a third dual-shaft motor 303 are fixedly connected inside the machine head 3. The first dual-shaft motor 301 is located between the second dual-shaft motor 302 and the third dual-shaft motor 303. A roller shutter 4 is fixedly connected to the output end of the first dual-shaft motor 301. The other end of the insulation curtain 10 is fixedly connected to the roller shutter 4. When the first dual-axis motor 301 rotates, it drives the roller shutter 4 to rotate, and at the same time causes the insulation curtain 10 to wind or unwind. Since the other end of the insulation curtain 10 is fixedly connected to the top of the greenhouse 1, it provides traction force to realize the up and down movement of the machine head 3. The output end of the second dual-axis motor 302 is fixedly connected to the upper cleaning roller 5, and the output end of the third dual-axis motor 303 is fixedly connected to the lower cleaning roller 6. Rollers 7 are connected to both ends of the roller shutter 4, the upper cleaning roller 5, and the lower cleaning roller 6 to facilitate contact with the walls at both ends of the greenhouse 1 and provide support force. A baffle 9 is set between the upper cleaning roller 5 and the roller shutter 4. One side of the baffle 9 is fixedly connected to the machine head 3. The installation height of the baffle 9 can be determined according to the height of the greenhouse 1. The installation height of the baffle 9 needs to be higher than the height of the roller shutter 4 when the insulation curtain 10 is fully wound.

[0018] It should be noted that the dual-output shaft motor used in this example is an existing device, and its specific mechanism will not be described in detail.

[0019] To increase the stability of the device, both ends of the upper cleaning roller 5 and the lower cleaning roller 6 are connected to the roller shutter roller 4 through the connecting plate 8, and the other side of the baffle 9 is fixedly connected to the connecting plate 8.

[0020] To ensure connection stability while meeting motion trajectory requirements, the other end of the bracket 2 is hinged to the machine head 3 through a pin and pin seat structure.

[0021] To facilitate operation by operators, a controller 11 is fixedly connected to the lower part of the bracket 2. The first dual-output shaft motor 301, the second dual-output shaft motor 302, and the third dual-output shaft motor 303 are all controlled by the controller 11.

[0022] It should be noted that this device is suitable for greenhouses with a uniform front curvature. Otherwise, changes in the front curvature of the greenhouse will cause changes in the relative positions of the upper cleaning roller 5, lower cleaning roller 6, and roller shutter 4, which may easily cause breakage at the connection with the machine head 3. The upper cleaning roller 5 and lower cleaning roller 6 are wrapped with soft brushes, which can achieve the cleaning effect without scratching the plastic film or light-transmitting glass on the greenhouse 1.

[0023] The working process of this embodiment is as follows:

[0024] During the day, to provide sunlight for the crops, the machine head 3 is positioned at the top of the greenhouse 1. After snowfall, the controller 11 controls the first dual-shaft motor 301 to rotate counterclockwise and the third dual-shaft motor 303 to rotate clockwise. At this time, the roller shutter 4 rotates counterclockwise, and the insulation curtain 10 wrapped around the roller shutter 4 gradually unfurls from the roller shutter 4. Under the action of gravity, the machine head 3 gradually descends along the arc of the greenhouse 1, driving the lower cleaning roller 6 to descend. At the same time, the lower cleaning roller 6 rotates clockwise under the drive of the third dual-shaft motor 303, continuously clearing the snow accumulated on the greenhouse 1 downwards. When the lower cleaning roller 6 touches the ground, the controller 11 controls the first dual-shaft motor 301 and the third dual-shaft motor 303 to stop rotating, completing the snow removal. If the greenhouse 1 needs to continue receiving sunlight, the controller controls the first dual-shaft motor 301 to rotate clockwise, lifting the machine head 3.

[0025] After snowfall at night, since greenhouse 1 needs insulation, the machine head 3 is at its lowest point. After the snowfall stops, the operator can control the first dual-shaft motor 301 to rotate clockwise, and the second dual-shaft motor 302 and the third dual-shaft motor 303 to rotate counterclockwise via the controller 11. Under the action of the first dual-shaft motor 301, the insulation curtain 10 is continuously wound around the roller 4, causing the machine head 3 to rise continuously. Snow will gradually accumulate above the upper cleaning roller 5. At this time, the upper cleaning roller 5 rotates counterclockwise under the action of the second dual-shaft motor 302, continuously moving the snow on the insulation curtain 10 to the baffle 9. The snow on the baffle 9 will gradually fall onto the film of greenhouse 1 under the action of gravity. When the machine head 3 rises to its highest point, the snow that has not been moved and accumulated on one side of the upper cleaning roller 5 will be removed. For any remaining snow, workers will climb up the side wall ladder 101 to the path on the back wall 103 to clear it, preventing it from affecting the insulation curtain 10 after melting. After the workers have cleared the remaining snow on one side of the upper cleaning roller 5, the controller 11 will control the first double-axis motor 301 to rotate counterclockwise and the third double-axis motor 303 to rotate clockwise, causing the machine head 3 to descend. During the descent, the lower cleaning roller 6 will clean the snow that just fell onto the film of the greenhouse 1. When the lower cleaning roller 6 reaches the lowest point, the controller 11 will control the first double-axis motor 301 and the third double-axis motor 303 to stop rotating, completing the snow removal. If the greenhouse 1 needs to continue receiving sunlight, the first double-axis motor 301 will be controlled to rotate clockwise to lift the machine head 3.
