Description

Technical Field

[0001] This utility model relates to the field of shade net technology, and in particular to a shade net. Background Technology

[0002] Currently, agricultural greenhouses are being used more and more widely in agricultural planting. Since the surface of agricultural greenhouses is only covered with a layer of plastic film, although it can play a good role in heat preservation, it cannot block sunlight. Especially in the hot summer, due to the strong ultraviolet rays, it can easily damage the crops inside the greenhouse. In order to solve the problem of strong sunlight, people mostly use shade nets to cover the surface of the greenhouse film to block strong light. However, the existing shade nets are mainly covered on the surface of the greenhouse manually, which is not only difficult to operate, but also difficult to put away and take off after covering, thus making it impossible to regulate the amount of sunlight received by the greenhouse.

[0003] For example, Chinese Patent Publication No. CN218184303U describes a shade net for greenhouse planting, which relates to the field of shade net installation. It includes two arched frames, a drive mechanism installed on one side of one of the arched frames, and two transmission mechanisms symmetrically installed on the two arched frames. Each transmission mechanism includes a first transmission component and two second transmission components. Adjacent first and second transmission components are connected to each other. One side of each first transmission component is connected to both sides of one end of the same shade net. One second transmission component is connected to one side of the drive mechanism. The drive mechanism drives the second transmission component to rotate, thereby causing the first transmission component to rotate and move the shade net.

[0004] However, in the above solution, the device is not convenient to block the mesh of the shade net when in use, which causes light to shine into the greenhouse through the mesh of the shade net. If an opaque shade net is used, the plants in the greenhouse will lack sunlight, thus affecting the growth of the plants. Utility Model Content

[0028] Please see Figure 1-7 In this embodiment of the utility model, a shade net includes a greenhouse 1. Arc-shaped outer shells 5 are fixedly connected to both sides of the top of the greenhouse 1. Gear racks 2 are fixedly connected inside each of the two arc-shaped outer shells 5. Two sliding rods 6 are fixedly connected inside each of the two arc-shaped outer shells 5. Sliding plates 9 are slidably connected to the outer sidewalls of the two sliding rods 6 inside the two arc-shaped outer shells 5. Motors 14 are fixedly connected to the sidewalls of the two sliding plates 9. Gears 13 are fixedly connected to one end of the output shafts of the two motors 14. The two gears 13 are respectively meshed with the two gear racks 2. A first shade net 3 and a second shade net 4 are connected between the two arc-shaped outer shells 5 through a winding structure. One end of the second shade net 4 is fixedly connected to the sidewalls of the two sliding plates 9, and one end of the first shade net 3 is connected to the sidewalls of the two sliding plates 9 through a reset structure.

[0029] Please see Figure 1 , Figure 3 , Figure 6 The winding structure includes two winding rods 7, which are rotatably connected between two arc-shaped shells 5. The first sunshade cloth 3 and the second sunshade cloth 4 are respectively wound around the outer sidewalls of the two winding rods 7. One end of each winding rod 7 passes through one of the arc-shaped shells 5, and a rotating plate 17 is fixedly connected to one end of each winding rod 7. The sidewalls of the two rotating plates 17 are provided with fixing structures. By rotating the two winding rods 7, and then by starting the two 14 to rotate in opposite directions, the first sunshade mesh cloth 3 and the second sunshade mesh cloth 4 can be wound up.

[0030] Please see Figure 3 , Figure 6 Both fixed structures include bolts 16, which are movably connected to the side walls of the two rotating plates 17. One end of each bolt 16 passes through the corresponding rotating plate 17. One of the arc-shaped outer shells 5 has two sets of threaded grooves 15 on its side wall. Multiple threaded grooves 15 are arranged in a ring array. One end of each bolt 16 is threaded into one of the two sets of threaded grooves 15. By turning the two bolts 16, the bolts 16 can be removed, thereby releasing the bolts from fixing the rotating plate 17 and allowing the two winding rods 7 to rotate freely. By screwing the two bolts 16 into different threaded grooves 15, the two winding rods 7 can be fixed.

[0031] Please see Figure 3 , Figure 6 Both rotating plates 17 have rotating rods 18 rotatably connected to their side walls. Rotating the two rotating rods 18 can drive the two rotating plates 17 to rotate, making it more convenient.

[0032] Please see Figure 1-2 , Figure 4-5 The reset structure includes two sliding grooves 10, which are respectively opened on the side walls of two sliding plates 9. A spring 12 is fixedly connected in each of the two sliding grooves 10. A sliding block 11 is fixedly connected to one end of each of the two springs 12. The two sliding blocks 11 are slidably connected to the two sliding grooves 10. One end of the first shading cloth 3 is fixedly connected to the side wall of the two sliding blocks 11. By rotating the winding rod 7 in the opposite direction, the winding rod 7 releases the tension on the first shading mesh cloth 3. The two springs 12 can drive the first shading mesh cloth 3 to automatically reset, so that the mesh of the first shading mesh cloth 3 and the side wall of the second shading mesh cloth 4 are misaligned, thereby shading the greenhouse 1.

[0033] Please see Figure 1 , Figure 3A protective shell 8 is fixedly connected between the two arc-shaped outer shells 5. The two winding rods 7 are located inside the protective shell 8. The top of the protective shell 8 is hollowed out, and the protective shell 8 can protect the two winding rods 7.

[0034] The working principle of this utility model is as follows: When the first shading mesh 3 and the second shading mesh 4 are needed, the two bolts 16 can be removed by unscrewing them, thereby releasing the bolts 16 from fixing the rotating plate 17. This allows the two winding rods 7 to rotate freely, which in turn starts the two motors 14. The output shafts of the two motors 14 drive the two gears 13 to rotate, causing the two gears 13 to move on the surfaces of the two gear racks 2. This, in turn, moves the motors 14 and the sliding plate 9. When the two sliding plates 9 move, they can pull the first shading mesh 3 and the second shading mesh 4, thus laying the first shading mesh 3 and the second shading mesh 4 on the top of the greenhouse 1. At this time, the mesh openings of the first shading mesh 3 and the second shading mesh 4 are misaligned. Then, by screwing two bolts 16 into different threaded grooves 15, the two winding rods 7 can be fixed. By rotating one of the winding rods 7, the first shading mesh 3 can be moved, causing the first shading mesh 3 to pull the sliding block 11 to slide in the sliding groove 10, so that the mesh of the first shading mesh 3 and the second shading mesh 4 overlap, allowing light to shine into the greenhouse 1 through the mesh, thereby adjusting the amount of sunlight received by the greenhouse 1. By rotating the winding rod 7 in the opposite direction, the winding rod 7 can release the tension on the first shading mesh 3, and the two springs 12 can drive the first shading mesh 3 to automatically reset, so that the mesh of the first shading mesh 3 and the second shading mesh 4 are misaligned, thereby shading the greenhouse 1.
