Description

Technical Field

[0001] This utility model relates to the technical field of greenhouse shading mechanisms, and in particular to an agricultural greenhouse shading mechanism. Background Technology

[0002] Agricultural greenhouses are artificially controlled planting environments, mainly used to regulate conditions such as temperature, humidity, and light to optimize crop growth, extend the planting cycle, or achieve off-season cultivation. The greenhouse shading mechanism is an important component of modern agricultural greenhouses, mainly used to regulate light intensity and control temperature, thereby optimizing the crop growth environment.

[0003] A search of Chinese Patent Publication No. CN221784810U reveals a greenhouse shading device, comprising a greenhouse, a support frame, a shading cloth, a moving mechanism, and a partition. The support frame is fixedly connected to the top of the greenhouse, and the moving mechanism is movably connected to the support frame. The shading cloth is installed on the top of the support frame. A partition is movably connected to the right side of the moving mechanism, and a positioning cavity is formed on the right side of the partition, containing a positioning mechanism. This invention, through the coordinated use of the greenhouse, support frame, shading cloth, moving mechanism, partition, and positioning mechanism, overcomes the limitations of existing methods of laying shading cloth, which rely on manual labor. This manual method is prone to causing injury, is inconvenient, and inefficient, especially when laying shading cloth on taller greenhouses. To facilitate safe and convenient use of shading cloth, this greenhouse shading device automatically expands or contracts the shading cloth via a controller, simplifying operation and reducing the risk of injury.

[0004] However, in implementing the relevant technology, the following problems were found with the above-mentioned sunshade device: the existing technology uses a servo motor to drive the sunshade cloth to unfold, but when it is necessary to retract the sunshade cloth, simply using the servo motor to drive the moving mechanism to retract cannot roll up the sunshade cloth. Therefore, manual operation is still required when retracting the sunshade cloth, which is not convenient to use. Based on this, this utility model designs an agricultural greenhouse sunshade mechanism to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a shading mechanism for agricultural greenhouses to solve the problem mentioned in the background art that the existing technology is not convenient and quick enough when rolling up the shading cloth.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an agricultural greenhouse shading mechanism, comprising a support frame one and a support frame two, a guide beam installed on the top outer wall of the support frame one and the support frame two, a support base one installed on one side wall of the support frame two, a winding rod one rotatably connected to the support base one, a shading cloth wound around the side wall of the winding rod one, a traction rod installed at one end of the shading cloth, and the traction rod slidably engaging with the guide beam;

[0007] Support base 2 is installed on one side wall of support frame 1. A winding roller 2 is rotatably connected to support base 2. A traction rope is wound around the side wall of winding roller 2, and one end of the traction rope is connected to the traction rod.

[0008] A fixed side plate is installed on one side wall of the second support frame. Support side plates are installed on one side wall of both the first support frame and the fixed side plate. A positioning sleeve is rotatably connected to the support side plate. A movable shaft is slidably engaged on the positioning sleeve. A locking base plate is installed at one end of the movable shaft. A fixed shaft is installed on one side wall of the locking base plate. A positioning plate is installed at one end of both the second winding roller and the first winding roller.

[0009] As a preferred embodiment, limit strips are installed on the side walls of the movable shaft, and the limit strips are slidably engaged with the positioning sleeve.

[0010] As a preferred embodiment, an electric telescopic rod is installed on one side wall of the support side plate, an adjustment plate is connected to the output end of the electric telescopic rod, a top rod is installed on one side wall of the adjustment plate, and the top rod is slidably engaged with the positioning sleeve.

[0011] As a preferred embodiment, the movable shaft is internally slidably engaged with a support limiting shaft, and a support spring is provided on the side wall of the support limiting shaft.

[0012] As a preferred embodiment, a drive motor is installed on one side wall of the support side plate, and a drive pulley is connected to the output end of the drive motor. A driven pulley is installed on the side wall of the positioning sleeve, and the drive pulley is connected to the driven pulley via a transmission belt.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figure 1-8The diagram illustrates a shading mechanism for an agricultural greenhouse, comprising a support frame 1 and a support frame 2. Guide beams 3 are installed on the top outer walls of both support frames 1 and 2. A support base 4 is installed on one side wall of support frame 2. A winding rod 5 is rotatably connected to support base 1. A shading cloth 6 is wound around the side wall of winding rod 1. A traction rod 7 is installed at one end of the shading cloth 6 and is slidably engaged with the guide beam 3. Two support bases 2 8 are symmetrically installed on one side wall of support frame 1. A winding rod 2 9 is rotatably connected to support base 2 8. Traction ropes 10 are wound around the side wall of winding rod 2 9. The two traction ropes 10 on winding rod 2 9 are wound around the two support bases 1. Inside the base 2 8, one end of the traction rope 10 is connected to the traction rod 7. A fixed side plate 12 is installed on one side wall of the support frame 2. Support side plates 13 are installed on one side wall of the support frame 1 and the fixed side plate 12. A positioning sleeve 14 is rotatably connected to the support side plate 13. A movable shaft 15 is slidably engaged on the positioning sleeve 14. A base plate 16 is installed at one end of the movable shaft 15. A fixed shaft 17 is installed on one side wall of the base plate 16. A positioning plate 11 is installed at one end of the winding roller 2 9 and the winding roller 1 5. Positioning holes are opened on the positioning plates 11, and the positions of the positioning holes correspond one-to-one with the positions of the fixed shafts 17. Limiting strips 18 are installed on the side wall of the movable shaft 15, and the limiting strips 18 are slidably engaged with the positioning sleeve 14. The positioning sleeve 14 has a guide groove, the length of which is greater than the length of the limiting strip 18, allowing the limiting strip 18 to slide inside the guide groove. When the positioning sleeve 14 rotates, the limiting strip 18 allows the movable shaft 15 to rotate synchronously with the positioning sleeve 14. An electric telescopic rod 19 is installed on one side wall of the support side plate 13. The electric telescopic rod 19 is a mechanical device, also known as an electric push rod or electric linear actuator, which is a mechanical device that converts electrical energy into linear motion. An adjusting plate 20 is connected to the output end of the electric telescopic rod 19. A push rod 21 is installed on one side wall of the adjusting plate 20. One end of the push rod 21 is slidably connected to a support ball, and the push rod 21 is slidably engaged with the positioning sleeve 14. The movable shaft 15 is also slidably engaged internally. A supporting limiting shaft 22 is provided, and a supporting spring 27 is provided on the side wall of the supporting limiting shaft 22. When sun shading is required, the electric telescopic rod 19 on the support frame 1 drives the adjusting plate 20 to move, so that the top rod 21 can move against the movable shaft 15. This allows the fixed shaft 17 on the locking base plate 16 to engage with the positioning plate 11 at one end of the winding roller 9. Then, by driving the positioning sleeve 14 to rotate, the positioning sleeve 14 can drive the movable shaft 15 to rotate, which in turn drives the winding roller 9 to rotate through the positioning plate 11. This allows the traction rope 10 to wind around the side wall of the winding roller 9, so that the traction rope 10 can pull the traction rod 7 to move. The traction rod 7 pulls the sunshade cloth 6 on the winding roller 5 to unfold, thus completing the unfolding of the sunshade cloth 6.Furthermore, when sunshade is not needed, the electric telescopic rod 19 on support frame 1 first drives the top rod 21 to retract. When the top rod 21 retracts, the support spring 27 drives the support limiting shaft 22 to move, allowing the support limiting shaft 22 to separate the locking base plate 16 from the positioning plate 11. Then, following the above method, the electric telescopic rod 19 on support frame 2 can drive the corresponding movable shaft 15 to move, causing the fixed shaft 17 on the corresponding locking base plate 16 to engage with the positioning plate 11 at one end of the winding roller 5. Then, the winding roller 5 can be rotated, allowing the sunshade cloth 6 to be wound around the side wall of the winding roller 5, thus completing the winding of the sunshade cloth 6. This device, by driving the winding roller 5 and the winding roller 9 to rotate respectively, allows the sunshade cloth 6 to be easily and quickly unfolded and rolled up, improving the ease of use of the device.

[0027] In this embodiment, as Figure 5 As shown, a drive motor 23 is installed on one side wall of the support side plate 13. A drive pulley 24 is connected to the output end of the drive motor 23. A driven pulley 25 is installed on the side wall of the positioning sleeve 14. The drive pulley 24 is connected to the driven pulley 25 through a transmission belt. The drive motor 23 drives the drive pulley 24 at its output end to rotate, so that the driven pulley 25 can drive the positioning sleeve 14 to rotate.

[0028] In this embodiment, as Figure 7 As shown, support rollers 26 are installed at both ends of the traction rod 7. The support rollers 26 at both ends of the traction rod 7 support the traction rod 7, so that the traction rod 7 can slide more smoothly inside the guide beam 3.

[0029] Working principle of this utility model: This utility model is a sunshade mechanism for agricultural greenhouses. When sunshade is needed, the electric telescopic rod 19 on the support frame 1 drives the adjustment plate 20 to move, so that the top rod 21 can move against the movable shaft 15. This allows the fixed shaft 17 on the bottom plate 16 to engage with the positioning plate 11 at one end of the winding roller 9. Then, by driving the positioning sleeve 14 to rotate, the positioning sleeve 14 can drive the movable shaft 15 to rotate, which in turn drives the winding roller 9 to rotate. This allows the traction rope 10 to wind around the side wall of the winding roller 9, which in turn drives the traction rod 7 to move, so that the traction rod 7 can pull the sunshade cloth 6 on the winding roller 5 to unfold.

[0030] When sunshade is not needed, the electric telescopic rod 19 on support frame 1 drives the top rod 21 to retract, so that the fixed shaft 17 on the locking base plate 16 can no longer engage with the positioning plate 11 on the winding roller 2 9. At the same time, the electric telescopic rod 19 on support frame 2 2 can drive the corresponding movable shaft 15 to move, so that the fixed shaft 17 on the locking base plate 16 engages with the positioning plate 11 at one end of the winding roller 1 5. Then, the winding roller 1 5 can be rotated, so that the sunshade cloth 6 can be rolled around the side wall of the winding roller 1 5. This device enables the sunshade cloth 6 to be easily and quickly unfolded and rolled up by driving the winding roller 1 5 and the winding roller 2 9 to rotate respectively.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
