[0066] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0067] Reference Figure 1-Figure 12 , an automatic rolling device for greenhouse quilts, including the automatic rolling device for greenhouse quilts comprising:

[0068] A greenhouse body 2 for installing a mounting frame 1, the mounting frame 1 is arranged on the front and rear sides of the greenhouse body 2, the lower end of the mounting frame 1 is an arch-shaped structure arranged corresponding to the longitudinal cross-sectional structure of the greenhouse body 2, the upper end of the mounting frame 1 is a gantry structure, and a weather forecast component 3 is arranged on the mounting frame 1, and a winding mechanism 4 is installed at the upper end of the mounting frame 1, wherein the hardware end of the weather forecast component 3 is based on a microcontroller, which is responsible for the central control and module data communication of all programs, and is matched with a wireless module for networking, a DHT11 sensor for detecting ambient temperature and humidity, and a control module for controlling the opening and closing of the winding mechanism 4, and the weather forecast data is obtained through the wireless module networking, so as to control in advance whether the winding mechanism 4 needs to be started, so as to achieve the effect of early prevention, and the ambient humidity is monitored in real time through the DHT11 sensor, so as to avoid the weather forecast data being received in time and causing the winding mechanism 4 to fail to perform the corresponding operation. It should be noted that: when the ambient temperature is low or it is raining, the winding mechanism 4 is started to lay the greenhouse quilt, so as to avoid the indoor temperature of the greenhouse being affected by the outside world and the temperature suddenly dropping, resulting in a negative impact on the growth of plants in the greenhouse.

[0069] The reeling mechanism 4 is used to automatically reel the greenhouse quilt. The reeling mechanism 4 is electrically connected to the weather forecasting component 3. The reeling mechanism 4 includes a reeling shaft 401, a motor 402 and a motor box 403. The components are arranged as follows:

[0070] The winding shaft 401 rotatably mounted on the mounting frame 1 is used to wind up the greenhouse quilt. The motor 402 mounted on the mounting frame 1 and electrically connected to the weather forecast component 3 is used to drive the winding shaft 401 to rotate. The motor box 403 mounted on the mounting frame 1 is used to install the motor 402 and protect the motor 402 from being affected by rain and wind and sand. A long heat dissipation hole is provided at the lower end of the motor box 403. The heat dissipation hole is provided to ensure the heat dissipation effect of the motor 402 in the motor box 403. A filter net is provided in the heat dissipation hole to block dust in the air, thereby preventing dust from accumulating in the motor box 403 and affecting the service life of the motor 402.

[0071] Based on the setting of the mounting frame 1 , in order to ensure that the laying direction of the greenhouse quilt is single and stable, a guiding mechanism 5 for guiding the laying direction of the greenhouse quilt is installed on the mounting frame 1 .

[0072] Further implementation method is that the guide mechanism 5 includes a guide opening 502 for slidingly fitting the guide rectangular plate 501, two guide slots 504 for slidingly fitting the guide mounting block 503, a support spring 505 fixedly connected between the guide slot 504 and the guide mounting block 503, four guide arc grooves 507 for slidingly fitting the guide beads 508 and a clamping roller 509 installed between two symmetrically arranged guide beads 508, and each component is arranged as follows:

[0073] The guide opening 502 is opened at the top position of the mounting frame 1, and the guide slide groove 504 is opened on the inner walls on both sides of the upper end of the mounting frame 1. The support spring 505 is used to provide elastic support for the guide mounting block 503. The guide roller 506 is fixedly connected between the two guide mounting blocks 503. The guide roller 506 is used to resist the greenhouse quilt wound on the winding shaft 401. By utilizing the elastic force of the support spring 505, when the guide mounting block 503 is not affected by external force, it tends to move to the initial state until it is reset, so that the guide roller 506 fixedly connected to the guide mounting block 503 is retractable, thereby ensuring that the guide roller 506 is always in contact with the greenhouse quilt during the winding process of the greenhouse quilt on the winding shaft 401, avoiding wrinkles in the greenhouse quilt during the winding process, which helps to improve the winding effect of the greenhouse quilt. The guide arc groove 507 is opened on the inner walls on both sides of the lower end of the mounting frame 1, and the clamping roller 509 is used to press and fix the lower end of the greenhouse quilt.

[0074] The clamping roller 509 includes a roller body 5092 for providing a limiting long hole 5091, a clamping plate 5093 disposed in the limiting long hole 5091, and a screw 5094 threadedly mounted on the roller body 5092. The components are arranged as follows:

[0075] The limiting long hole 5091 is used to guide and limit the greenhouse quilt, the clamping plate 5093 is used to roll up the greenhouse quilt, and the lower end of the screw 5094 is rotatably installed on the top position of the clamping plate 5093 located in the limiting long hole 5091. The screw 5094 is used to drive the clamping plate 5093 to rise and fall vertically. By using the screw 5094 as a driving source, the clamping roller 509 has self-locking properties in the process of pressing and fixing the lower end of the greenhouse quilt, which helps to ensure the stability of the pressing and fixing operation of the lower end of the greenhouse quilt. It should be noted that a handle is provided at the upper end of the screw 5094.

[0076] Based on the setting of the winding shaft 401, in order to facilitate the staff to disassemble and assemble the upper end of the greenhouse quilt, a clamping mechanism 6 for fixing and clamping the upper end of the greenhouse quilt is arranged on the winding shaft 401. The clamping mechanism 6 includes a fixed long groove 601 provided on the winding shaft 401, two abutment plates 602 slidably installed on the inner wall of the fixed long groove 601 close to the motor 402, a driving groove 603 provided on the inner wall of the mounting frame 1 away from the motor 402, a traction rod 604 with a pin installed on one end of the abutment plate 602 close to the driving groove 603, a driving rod 605 slidably installed on the outer wall of the mounting frame 1 away from the motor 402, a traction rope 606 installed on the outer end of the driving rod 605 and a winding wheel 607 installed on the outer wall of the lower end of the mounting frame 1. The various components are arranged as follows:

[0077] The fixed long slot 601 is opened on one side away from the motor 402 , the abutment plate 602 is used to abut and limit the upper end of the greenhouse quilt, the inner end of the driving slot 603 is opened, and the traction rod 604 is used to drive the two abutment plates 602 .

[0078] One end of the driving rod 605 close to the winding shaft 401 is pin-mounted on one end of the traction rod 604 located in the driving groove 603. The driving rod 605 is used to drive one end of the traction rod 604 to perform linear motion. It should be noted that: a movable through hole for the set driving rod 605 is opened on the mounting frame 1, and the driving rod 605 is composed of two cylinders, one of which is provided with a pin-mounting seat for installing the traction rod 604, and the other cylinder is provided with a connecting ring for connecting the traction rope 606, and the two cylinders are rotatably connected. The length of the cylinder for connecting the traction rope 606 is three times the length of the cylinder for pin-mounting the traction rod 604, and the sliding mode of the driving rod 605 and the mounting frame 1 is one of a slider and a slide groove or a slide rail and a slider, as follows:

[0079] Under the condition that the movable through hole has the same aperture, when the slider and the slide groove are used, there is no need to adjust the thickness of the driving rod 605, and the driving rod 605 adapted to the aperture of the movable through hole can be directly selected. When the slide rail and the slider are used, it is necessary to select a driving rod 605 smaller than the aperture of the movable through hole, but there is no need to destroy the hole structure of the movable through hole;

[0080] Therefore, when the winding shaft 401 rotates, the resistance plate 602 is driven to rotate as well, and the resistance plate 602 rotates through the traction rod 604. The cylinder used to connect the traction rope 606 is restricted by the slider and the slide groove or the slide rail and the slider and cannot rotate. However, since the two cylinders are rotatably connected, the cylinder used to pin-mount the traction rod 604 is affected by the traction rod 604 and rotates, thereby avoiding motion interference with the rotation of the winding shaft 401.

[0081] The middle end of the traction rope 606 passes through and extends into the guide arc groove 507. The traction rope 606 is slidably mounted on the guide bead 508. The movement of the guide bead 508 is guided and limited by the traction rope 606 to prevent the guide bead 508 from rotating in the guide arc groove 507. It should be noted that when the greenhouse quilt is installed on the winding shaft 401, the traction rope 606 is in a tightened state. The lower end of the traction rope 606 passes through and extends to the outer side of the lower end of the mounting frame 1. The winding wheel 607 is used to wind the lower end of the traction rope 606.

[0082] Based on the setting of the clamping mechanism 6, in order to ensure the fixing effect of the clamping mechanism 6 on the greenhouse quilt, a limiting mechanism 7 for limiting the rotation of the winding wheel 607 is provided on the lower end of the mounting frame 1. The limiting mechanism 7 includes a bracket 702 for slidingly mounting a limiting rod 701, a limiting ring 703 installed on the limiting rod 701, and a return spring 704 fixedly connected between the bracket 702 and the limiting ring 703. The components are arranged as follows:

[0083] The lower end of the limiting rod 701 passes through and extends to the winding wheel 607, the bracket 702 is fixedly mounted on the outer wall of the lower end of the mounting frame 1, the limiting ring 703 and the winding wheel 607 are movable against each other, and the reset spring 704 is used to provide a reset function for the limiting ring 703. Through the elastic force of the reset spring 704, the limiting ring 703 drives the limiting rod 701 to move toward the initial state until it is reset when not affected by external force.

[0084] The present invention can be explained by the following operation mode:

[0085] The weather forecast component 3 receives weather environment data. When the ambient temperature is low or it is raining, the motor 402 is started. The motor 402 drives the winding shaft 401 to rotate, and the lower end of the greenhouse quilt drives the clamping roller 509 to move downward. At this time, the number of winding layers at the upper end of the greenhouse quilt is reduced. Under the elastic force of the support spring 505, the guide mounting block 503 moves toward the initial state in the guide slide groove 504. The guide mounting block 503 drives the guide roller 506 to move vertically downward, so that the guide roller 506 always contacts the activity of the greenhouse quilt. The guide roller 506 drives the guide rectangular plate 501 to move vertically downward in the guide opening 502. The clamping roller 509 drives the guide bead 508 to move along the opening trajectory of the guide arc groove 507, so that the greenhouse quilt is laid along the preset movement trajectory;

[0086] When the surface of the greenhouse quilt is damaged and needs to be replaced, the limit rod 701 is pulled, and the limit rod 701 drives the limit ring 703 to move vertically upward. The limit ring 703 squeezes the return spring 704, so that the limit rod 701 is away from the winding wheel 607, and the driving rod 605 is pushed inward. At this time, the driving rod 605 drives the traction rope 606 to move upward, and the driving rod 605 drives one end of the traction rod 604 to move linearly. The other end of the traction rod 604 drives the contact plate 602 to move away from the greenhouse quilt, so that the contact plate 602 is no longer fixed to the upper end of the greenhouse quilt, and the screw 5094 is rotated, and the screw 5094 drives the clamping plate 5093 to move upward, so that the clamping plate 5093 is no longer fixed to the lower end of the greenhouse quilt, so that the staff can take off the greenhouse quilt;

[0087] Insert the upper end of the new greenhouse quilt into the fixed long groove 601, rotate the winding wheel 607, so that the lower end of the traction rope 606 is wound on the winding wheel 607, and the traction rope 606 drives the driving rod 605 to move vertically downward, and the driving rod 605 drives one end of the traction rod 604 to perform linear motion, and the other end of the traction rod 604 drives the contact plate 602 to fix the greenhouse quilt, and rotate the screw rod 5094 in the opposite direction, and the screw rod 5094 drives the clamping plate 5093 to fix the lower end of the greenhouse quilt, thereby completing the installation of the greenhouse quilt;

[0088] At this time, the limiting rod 701 is released, and under the elastic force of the reset spring 704, the limiting rod 701 drives the limiting ring 703 to move against the winding wheel 607, and the limiting rod 701 buckles and fixes the winding wheel 607.

[0089] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
