Description

Technical Field

[0001] This application relates to the field of agricultural facility technology, specifically to a device for opening and closing an inner shed for a greenhouse. Background Technology

[0002] The inner shading in existing greenhouses is mainly used to regulate the light and temperature environment inside the greenhouse. In summer, the inner shading can block some sunlight to prevent crops from being damaged by excessive light and temperature. In winter, the inner shading, together with the side shading, forms an insulated space to reduce heat loss and create a suitable growth temperature for crops.

[0003] However, the opening and closing of the inner canopy of existing greenhouses often relies on manual pulling. This requires operators to walk back and forth inside the greenhouse and pull the canopy section by section, which is a very tedious process that consumes a lot of manpower and time. This is especially true for larger greenhouses, where manual operation is even more difficult. Although some greenhouses use some simple mechanical devices to assist in opening and closing, they often lack efficient drive systems and cannot accurately control the speed and stroke of opening and closing, which may lead to uneven opening and closing of the canopy or jamming during the process.

[0004] Therefore, it is necessary to provide a device for opening and closing an inner shed for greenhouses to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] The purpose of this utility model is to provide a device for retracting and extending an inner shed for greenhouses, so as to solve the problems of inconvenience in retracting and extending existing inner sheds for greenhouses and poor stability mentioned in the background art.

[0007] The technical solution adopted by this application to solve its technical problem is:

[0008] A retraction device for an inner shed in a greenhouse, the greenhouse including a greenhouse wall and a frame installed on the greenhouse wall, wherein retraction components are installed on both sides of the greenhouse wall, and one of the retraction components is driven by a drive motor;

[0009] The moving mechanism is retracted and extended by two sets of retracting components. The surface of the moving mechanism is fixedly installed on one side of the inner canopy, and the other side of the inner canopy is fixedly installed on the canopy frame.

[0010] The moving mechanism includes a first steel rope and a second steel rope. The two ends of the first steel rope and the second steel rope are respectively wound around the take-up and release assembly, and the winding directions of the first steel rope and the second steel rope are opposite. One side of the inner canopy is fixedly installed with the first steel rope.

[0011] Preferably, the take-up and release assembly includes a rotating rod and a plurality of take-up and release rollers. The plurality of take-up and release rollers are fixedly installed on the side wall of the rotating rod. The first steel rope and the second steel rope are respectively wound around the side wall of each take-up and release roller, and the first steel rope and the second steel rope are wound in opposite directions on the side wall of the take-up and release roller.

[0012] Preferably, support rods are fixedly installed on both inner sides of the greenhouse wall, and bearing seats are fixedly installed on the side walls of the support rods by D-type clamps, with the side walls of the rotating rods installed in the bearing seats.

[0013] Preferably, a movable rod is fixedly installed on one side of the inner canopy, and the movable rod is fixedly installed on the first steel rope. The other side of the inner canopy is fixedly installed on the canopy frame by a fixed rod.

[0014] Preferably, a limit rod is fixedly installed on the steel rope near the middle on one side of the inner canopy.

[0015] Preferably, a gear set is mounted on the top surface of the drive motor, and the output shaft of the drive motor is connected to the rotating rod through the gear set.

[0016] Preferably, cables are fixedly installed on both sides of the greenhouse wall, and multiple hanging rings are bolted to both sides of the inner canopy, with the multiple hanging rings respectively attached to the cables.

[0017] Preferably, a side canopy is detachably installed around the inner canopy, and both the side canopy and the inner canopy are made of non-woven fabric.

[0018] The beneficial effects of this application are:

[0019] This technical solution uses a drive motor in conjunction with a gear set, a rotating rod, and a take-up and release roller to replace the manual pulling of the inner canopy. After the drive motor is started, its power is transmitted to the rotating rod through the gear set, which drives the take-up and release roller to rotate, causing the first and second steel ropes to take up and down, thereby realizing the automatic take-up and release of the inner canopy. Operators no longer need to walk back and forth in the greenhouse to pull the canopy section by section, which greatly reduces manpower input and operation time. It is especially suitable for large-area greenhouses and greatly improves the efficiency of the take-up and release of the inner canopy.

[0020] Furthermore, by setting up a first and second steel rope with opposite winding directions, as well as multiple take-up and release rollers, the take-up and release speed and stroke of the inner canopy can be precisely controlled. When the rotating rod rotates forward and backward, the tightening and loosening states of the two steel ropes change accordingly, so that the first steel rope can smoothly drive the inner canopy to move, avoiding uneven take-up and release or jamming. At the same time, the limit rod can prevent the inner canopy from tipping over when it is fully retracted, and the cable and hanging ring structure ensures effective support on both sides of the inner canopy, further ensuring the stability and accuracy of the inner canopy during take-up and release.

[0040] 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.

[0041] 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.

[0042] Please see Figure 1-6 The embodiments provided by this utility model are as follows:

[0043] like Figure 1 and Figure 2 As shown, a retraction device for an inner awning in a greenhouse is disclosed. The greenhouse includes a greenhouse wall 1 and a frame 5 installed on the greenhouse wall 1. Retraction components 2 are installed on both sides of the greenhouse wall 1. One of the retraction components 2 is driven by a drive motor 6. The moving mechanism 3 is retracted and extended by the two sets of retraction components 2. The surface of the moving mechanism 3 is fixedly installed on one side of the inner awning 4, and the other side of the inner awning 4 is fixedly installed on the frame 5. After the drive motor 6 is started, it drives the retraction component 2 connected to it to operate. The retraction component 2 is retracted and extended through its relationship with the moving mechanism 3. Since there are retraction components 2 on both sides of the greenhouse wall 1, and one side is driven by the drive motor 6, the retraction and extension movement of the moving mechanism 3 is controlled by the coordinated action of the retraction components 2 on both sides. The inner awning 4 is fixed on one side to the moving mechanism 3 and on the other side to the frame 5. Therefore, the movement of the moving mechanism 3 can drive the inner awning 4 to retract and extend.

[0044] like Figure 3 and Figure 4 As shown, the moving mechanism 3 includes a first steel rope 31 and a second steel rope 32. The two ends of the first steel rope 31 and the second steel rope 32 are respectively wound around the take-up and take-down assembly 2, and the winding directions of the first steel rope 31 and the second steel rope 32 are opposite. One side of the inner canopy 4 is fixedly installed with the first steel rope 31.

[0045] Specifically, the take-up and release assembly 2 includes a rotating rod 21 and multiple take-up and release rollers 22. The multiple take-up and release rollers 22 are fixedly installed on the side wall of the rotating rod 21. The first steel rope 31 and the second steel rope 32 are respectively wound around the side wall of each take-up and release roller 22, and the first steel rope 31 and the second steel rope 32 are wound in opposite directions on the side wall of the take-up and release roller 22. A gear set is installed on the top surface of the drive motor 6, and the output shaft of the drive motor 6 is connected to the rotating rod 21 through the gear set.

[0046] After the drive motor 6 starts, its output shaft rotates, transmitting power to the rotating rod 21 through the gear set. This causes the rotating rod 21 to rotate, and as it rotates, multiple take-up and release rollers 22 fixed to its side wall rotate synchronously. Since the first steel rope 31 and the second steel rope 32 are wound around the take-up and release rollers 22 in opposite directions, when the rotating rod 21 rotates clockwise, the take-up and release rollers 22 tighten one steel rope while loosening the other. When the rotating rod 21 rotates counterclockwise, the tightening and loosening states of the steel ropes are reversed. Thus, the first steel rope 31 moves back and forth in a specific direction within the greenhouse under the action of the take-up and release rollers 22. Because one side of the inner canopy 4 is fixed to the first steel rope 31, the inner canopy 4 also retracts and expands along with the movement of the first steel rope 31. Through the cooperation of the rotating rod 21, the take-up and release rollers 22, and the gear set, the rotational power of the drive motor 6 is effectively converted into the retraction and expansion motion of the steel ropes, providing a stable and reliable power source and motion control mechanism for the retraction and expansion of the inner canopy 4.

[0047] It is worth noting that, such as Figure 3 As shown, support rods 7 are fixedly installed on both inner sides of the greenhouse wall 1. Bearing seats 71 are fixedly installed on the side walls of the support rods 7 by D-type clamps. The side walls of the rotating rod 21 are installed in the bearing seats 71 so that the rotating rod 21 can rotate on both sides of the greenhouse wall 1. The support rods 7 are fixedly installed on both inner sides of the greenhouse wall 1 to provide support and fixing points for the bearing seats 71. The bearing seats 71 are firmly installed on the side walls of the support rods 7 by D-type clamps. The rotating rod 21 is installed in the bearing seats 71. By utilizing the support and friction reduction characteristics of the bearing seats 71, the rotating rod 21 can rotate flexibly and smoothly on both sides of the greenhouse wall 1 when it is powered by the drive motor 6 through the gear set, reducing the resistance and wear of the rotating rod 21 during the rotation process.

[0048] like Figure 5 As shown, a movable rod 41 is fixedly installed on one side of the inner canopy 4, and the movable rod 41 is fixedly installed on the first steel rope 31. The other side of the inner canopy 4 is fixedly installed on the canopy frame 5 through a fixed rod 43. The movable rod 41 is fixedly connected to the first steel rope 31. When the first steel rope 31 is moved by the retraction component 2, the movable rod 41 will move synchronously with the first steel rope 31. Since the movable rod 41 is fixed on one side of the inner canopy 4, the inner canopy 4 will also move with the movement of the movable rod 41. The other side of the inner canopy 4 is fixed on the canopy frame 5 through the fixed rod 43, which serves to fix the other side of the inner canopy 4, so that the inner canopy 4 can be unfolded and retracted with the fixed rod 43 as the fulcrum under the drive of the movable rod 41. This ensures that the inner canopy 4 can stably follow the movement of the first steel rope 31 during the unfolding process and remains fixed in the unfolded state. This provides a reliable connection and fixing structure for the unfolding of the inner canopy 4, ensuring the accuracy and stability of the unfolding of the inner canopy 4.

[0049] Furthermore, a limiting rod 42 is fixedly installed on one side of the inner canopy 4 near the middle of the steel rope. The function of the limiting rod 42 is to block one side of the inner canopy 4 when it is retracted, so as to prevent the inner canopy 4 from tipping over when it is retracted. When the drive motor 6 drives the retraction assembly 2 to gradually retract the inner canopy 4, the inner canopy 4 moves towards the fixed rod 43 along with the first steel rope 31. When the inner canopy 4 is retracted to a certain position, the limiting rod 42 near the middle steel rope will block one side of the inner canopy 4, restricting the inner canopy 4 from continuing to move, preventing the inner canopy 4 from tipping over due to excessive movement or uneven force, so that the inner canopy 4 can be retracted neatly and stably.

[0050] Among them, such as Figure 4 As shown, cables 8 are fixedly installed on both sides of the greenhouse wall 1, and multiple hanging rings 81 are attached to both sides of the inner canopy 4. The multiple hanging rings 81 are respectively sleeved on the cables 8. During the retraction and extension movement of the inner canopy 4 by the retraction and extension component 2 and the moving mechanism 3, the two sides of the inner canopy 4 slide on the cables 8 through the multiple hanging rings 81 to ensure that the two sides of the inner canopy 4 can also be effectively supported, thus ensuring that the entire inner canopy 4 maintains a certain plane.

[0051] like Figure 6 As shown, a side canopy 9 is detachably installed around the inner canopy 4. Both the side canopy 9 and the inner canopy 4 are made of non-woven fabric. The inner canopy 4 and the side canopy 9 form an inner insulation space in the greenhouse to provide insulation for the crops inside in winter. When it is necessary to insulate the crops, the side canopy 9 is installed on the inner canopy 4 to form a relatively closed inner space in the greenhouse. This reduces the loss of heat in the greenhouse, blocks the entry of cold air, and maintains the internal temperature, thus providing a suitable growing temperature environment for the crops in winter. When insulation is not needed, the side canopy 9 can be removed for other operations and use of the greenhouse. Both the inner canopy 4 and the side canopy 9 are made of non-woven fabric and have certain insulation properties.

[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.
