Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of greenhouses, and in particular relates to a greenhouse shading device. Background Art
[0002] Greenhouses were originally special equipment for vegetable production. With the development of production, greenhouses have been used more and more widely. Currently, greenhouses are used for potted and cut flower cultivation, and fruit tree production for cultivating grapes, strawberries, watermelons, melons, peaches and citrus.
[0003] In the existing greenhouse shading equipment, a sunshade net is usually directly laid on the top of the greenhouse to block the sunlight. The sunshade net is usually retracted and released directly by a motor or manually. The sunshade net is usually needed in midsummer. In the hot summer, the summer rain comes quickly and there is no time to reel in the sunshade net. If the sunshade net is drenched by rain, a lot of water droplets will be absorbed and remain on the net surface, which will cause damage to the coating on the net surface and reduce the sun protection effect. In addition, after being washed by heavy rain and then exposed to the sun, it is easy to cause deep fabric fiber cracking, decay and other defects, shortening the service life of the sunshade net.
[0004] In view of this, the inventor conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Utility Model Content
[0005] The purpose of the utility model is: a greenhouse shading device, which can quickly squeeze out rainwater on the surface of the sunshade net when the sunshade net is rolled up after being rained on, reduce damage to the net surface coating, and increase the service life of the sunshade net.
[0006] A greenhouse shading device, comprising a sunshade mesh cloth covering a greenhouse main body, and also comprising a reeling mechanism for reeling in the sunshade mesh cloth, an unfolding mechanism for unfolding the sunshade mesh cloth, and a mounting frame; the reeling mechanism and the unfolding mechanism are respectively fixedly mounted on the mounting frame, and the reeling mechanism and the unfolding mechanism are respectively located at two ends of the sunshade mesh cloth; a dewatering assembly is also provided on the side of the reeling mechanism close to the unfolding mechanism, and the dewatering assembly comprises a first squeezing roller fixedly mounted on the reeling mechanism, and a second squeezing roller movably mounted on the reeling mechanism, the first squeezing roller and the second squeezing roller are arranged in parallel, and the first squeezing roller is located at the top of the sunshade mesh cloth, and the second squeezing roller is located at the bottom of the sunshade mesh cloth; the The extension direction of the axis of the first squeezing roller and the second squeezing roller is perpendicular to the winding direction of the sunshade mesh cloth; first mounting blocks are provided at both ends of the first squeezing roller, the first mounting blocks are fixedly mounted on the winding mechanism, and the first squeezing roller is rotatably connected to the first mounting blocks; second mounting blocks are provided at both ends of the second squeezing roller, the second mounting blocks are hinged to the winding mechanism, and the second squeezing roller is rotatably mounted on the second mounting blocks; the dewatering assembly also includes a driving spring, and the winding mechanism is also provided with a third mounting block for mounting the driving spring, the third mounting block is located below the second mounting block, one end of the driving spring is fixedly connected to the top of the third mounting block, and the other end is fixedly connected to the bottom of the second mounting block.
[0007] Furthermore, the reeling mechanism includes a first installation box, a first reeling roller rotatably installed in the first installation box, and a first motor driving the first reeling roller to rotate; a first slot for the sunshade mesh to pass through is formed on a side of the first installation box close to the unfolding mechanism; one end of the sunshade mesh is fixedly connected to the first reeling roller, and the first installation block, the second installation block, and the third installation block are all connected to the first installation box. When reeling, the first reeling roller can be driven to rotate quickly by the first motor to quickly reel the sunshade mesh into the first installation box.
[0008] Furthermore, the inner bottom of the first installation box has an inclined surface, which gradually inclines downward from an end close to the unfolding mechanism to an end away from the unfolding mechanism; a water-permeable groove is formed on the side of the first installation box away from the unfolding mechanism, and the water-permeable groove is connected to the lower end of the inclined surface. If the sunshade net is wetted by rain in heavy rain, after being rolled into the first installation box, the rainwater remaining on the sunshade net will drip onto the inclined surface and be discharged from the water-permeable groove along the inclined surface, thereby preventing water droplets from accumulating in the first installation box.
[0009] Furthermore, the unfolding mechanism includes a second installation box, a second winding roller rotatably installed in the second installation box, and a second motor driving the second winding roller to rotate. A second slot for the sunshade mesh to pass through is formed on one side of the second installation box close to the winding mechanism; the other end of the sunshade mesh is connected to the second winding roller through a plurality of cables, and the plurality of cables are arranged in parallel. When the greenhouse needs to be shaded, the second motor drives the second driving roller to rotate rapidly to reel up the cables, and the cables are used to pull the sunshade mesh out of the first installation box and flatten it to cover the greenhouse body.
[0010] Furthermore, the second winding roller is also fixedly mounted with a plurality of winding wheels, on which the cables are wound, so that the cables can be kept parallel during the winding process, thereby preventing the cables from being misaligned on the second winding roller, which may cause the sunshade fabric to be unable to be flattened.
[0011] Furthermore, the mounting frame is provided with two groups of stabilizing components, which are respectively located on both sides of the sunshade mesh. The stabilizing components include a fixing bar and a plurality of pulleys. A clamping groove for clamping the sunshade mesh is formed on the side of the fixing bar close to the sunshade mesh. A plurality of pulleys are installed in the clamping groove at equal intervals, and the pulleys are arranged in two rows, and the sunshade mesh is clamped between the two rows of pulleys. By arranging stabilizing components on both sides of the mounting frame, and using the clamping groove in the stabilizing components and the two rows of pulleys located in the clamping groove to clamp both sides of the sunshade mesh, the sunshade mesh can be prevented from being blown away by the wind, so that the sunshade effect is better.
[0012] After adopting the above structure, the utility model involves a greenhouse shading device. Compared with the prior art, the sunshade mesh is quickly unfolded through an unfolding mechanism. When encountering heavy rain, the sunshade mesh is quickly rolled up through a winding mechanism. If the sunshade mesh has been wet, during the rolling process, a large amount of rainwater on the sunshade mesh can be squeezed out by the first squeezing roller and the second squeezing roller in the water removal assembly, thereby preventing the sunshade mesh from directly bringing a large amount of rainwater into the rolling mechanism, reducing damage to the mesh coating, and increasing the service life of the sunshade mesh.
