Description

Technical Field

[0001] This utility model relates to the field of greenhouse accessories technology, specifically to a greenhouse shading net material blocking device. Background Technology

[0002] Currently, greenhouses are equipped with shade nets. In summer, when the sun is shining directly, a motor-driven rope is usually needed to unfold the shade nets. When the sun is out, the shade nets are then retracted. When the shade nets are retracted, they tend to clump together and tend to tilt backward, making them difficult to retract. Therefore, a blocking device needs to be installed at one end of the shade net to prevent it from tilting backward. Currently, most of these blocking devices are made of plastic, have a complex structure, and are inconvenient to install. In summer, after being exposed to high temperatures, the blocking devices are easily damaged and require frequent repairs and replacements, which is very inconvenient. Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

[0003] This utility model provides a greenhouse shade net blocking device, which aims to improve the current blocking components, which are mostly made of plastic, have complex structures, are inconvenient to install, and are easily damaged after being exposed to high temperatures in summer, requiring frequent maintenance and replacement, which is very inconvenient.

[0004] To achieve the above objectives, this utility model provides a greenhouse shading net material blocking device, the specific technical solution of which is as follows:

[0005] A material-blocking device for greenhouse shade netting includes a material-blocking plate. One side of the material-blocking plate has an inclined channel, and the middle of the material-blocking plate has a through groove. The inclined channel communicates with the through groove. A rope for pulling the shade netting up or down can enter the upper and lower ends of the through groove along the inclined channel. The rope passes through the through groove and through the material-blocking plate. Multiple through holes are provided on the lower side of the material-blocking plate, located on both sides of the through groove. Locking bolts are inserted into the through holes and screwed onto a fixing rod, thus fixing the material-blocking plate to the fixing rod. One end of the greenhouse shade netting is fixed to the fixing rod. When the shade netting is pulled up, the material-blocking plate can block the accumulated shade netting, preventing it from tilting backward.

[0006] In one embodiment, the two ropes are respectively located on the upper and lower sides of the fixed rod, and the two ropes pass through the baffle plate from the upper and lower ends of the through groove.

[0007] In one embodiment, the baffle plate is a polyethylene wear-resistant plate.

[0008] In one embodiment, an anti-loosening washer is fitted onto the locking bolt, and the anti-loosening washer is disposed between the nut of the locking bolt and the retaining plate.

[0009] The beneficial effects of this embodiment are:

[0010] By setting up a baffle plate with an inclined channel on one side and a through groove in the middle, the baffle plate allows the ropes used to pull the shade net up or down to enter the upper and lower ends of the through groove along the inclined channel. The ropes can then pass through the baffle plate through the through groove. When the shade net is pulled up, the baffle plate can block the accumulated shade net and prevent it from tipping backward, thus acting as a material blocking device. The baffle plate is made of polyethylene wear-resistant plate, which has the characteristics of high temperature resistance, wear resistance, and strength, greatly improving the service life of the baffle plate, effectively avoiding frequent replacements, and improving work efficiency.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] The technical solutions provided by the embodiments of this utility model are described below with reference to the accompanying drawings.

[0023] Please see Figure 4 An embodiment of this utility model provides a material blocking device for greenhouse shading nets, including a material blocking plate 100. The material blocking plate 100 is a polyethylene wear-resistant plate, which has the characteristics of high temperature resistance, wear resistance and strength, greatly improving the service life of the material blocking plate 100, effectively avoiding frequent replacement and improving work efficiency.

[0024] Please see Figure 1 and Figure 4 A sloping channel 110 is provided on one side of the baffle plate 100, and a through groove 120 is provided in the middle of the baffle plate 100. The sloping channel 110 is connected to the through groove 120. The rope 400 for pulling the shade net 310 to retract or unfold can enter the upper and lower ends of the through groove 120 along the sloping channel 110. The rope 400 can pass through the baffle plate 100 through the through groove 120.

[0025] Please see Figure 2 and Figure 3 The lower side of the baffle plate 100 is provided with multiple through holes 130, which are located on both sides of the through groove 120. Locking bolts 200 are inserted into the through holes 130 and screwed onto the fixing rod 300. The locking bolts 200 fix the baffle plate 100 to the fixing rod 300. One end of the shade net of the greenhouse is fixed to the fixing rod 300. When the shade net 310 is retracted, the fixing rod 300 moves forward and retracts. The baffle plate 100 on the fixing rod 300 can block the accumulated shade net 310 and prevent it from tilting backward, thus playing a role in blocking the material. Two ropes 400 are located on the upper and lower sides of the fixing rod 300, and the two ropes 400 pass through the baffle plate 100 from the upper and lower ends of the through groove 120, so that the baffle plate 100 avoids the ropes 400.

[0026] Please see Figure 3 Preferably, an anti-loosening washer 210 is fitted onto the locking bolt 200. The anti-loosening washer 210 is positioned between the nut of the locking bolt 200 and the baffle plate 100 to prevent the locking bolt 200 from loosening and falling off the fixing rod 300, thus playing an anti-loosening role.
