In order to ensure the normal passage of wind and reduce the wind resistance, a certain spacing is arranged between the adjacent two sand prevention nets 3, the fixing assemblies 4 are arranged below the two supporting assemblies 1 and are used for fixing the supporting assemblies 1 in the sand prevention position, so that the sand prevention net 3 is prevented from being blown down under the action of wind and sand force, sand prevention failure is avoided, the stability of the device is improved, the rotating assemblies 5 are rotatably arranged on the supporting assemblies 1, the covering net is arranged between the rotating assemblies 5, is used for forming an obstacle to flowing sand, reduces the sand flowing capacity, the connecting assemblies 6 are arranged between the rotating assemblies 5 and the supporting assemblies 1, so that the connecting assemblies 6, the rotating assemblies 5 and the supporting assemblies 1 form a triangular area, the stability of the device is improved, in the installation process, the rotating assemblies 5 can be pushed and supported by the connecting assemblies 6, so that the covering net on the rotating assemblies 5 is better attached to the sand surface, and in the working process, the covering area formed by the rotating assemblies 5 and the covering net effectively limits the supporting assemblies 1, and the swing of the supporting assemblies 1 is reduced. It should be noted that the sand prevention net 3 can be a plastic net, a flexible net (a textile net, a fiber net or a woven net) or a metal net, and is selected according to actual needs.

[0067] The rotating assembly 5 comprises a rotating rod 51, a rotating shaft 52 and a plurality of hooks 53. The rotating shaft 52 is installed at one end of the rotating rod 51 and is installed between the upper slot hole 19 and the lower slot hole 43.

Then, the position of the second connecting ring 54 is changed by moving the sliding block in the strip-shaped sliding groove. Then, the second connecting ring 54 is rotated, so that the strip-shaped fixed net can be tightened while being deflected by a small angle. Thus, the strip-shaped fixed net can be adjusted according to the direction of wind and sand blowing, thereby achieving better ground wind prevention and sand fixation effect.

The first connecting ring 14 is installed on one side of the support column 11. The connecting block 15 is installed on one side of the support column 11. The connecting frames 16 are installed on the support column 11. The two connecting frames 16 are installed on different sides of the support column 11, facilitating angle adjustment during assembly. The plurality of first through holes 17 are linearly arrayed on the support column 11 and communicate with the limiting cavity 13. The base 18 is installed at the bottom of the support column 11.

The other end is connected with the installation column 121. The installation column 121 is in sliding fit with the limiting cavity 13.

The blocking plate (not shown in the figure) is mounted on the top of the supporting column 11, so that the positioning block 23 is limited in the mounting groove 123.

[0071] When the sand prevention net 3 is a flexible net, the sand prevention net 3 may be relaxed due to improper installation position or insufficient tensioning of manpower after preliminary installation. When the sand prevention net 3 is relaxed, the wind resistance is increased, and the shaking of the whole device is also increased, so that the dust prevention effect and the service life are reduced. The distance needs to be adjusted again, and the operation is complicated. In the present application, the bolt is screwed through the first through hole 17 and the threaded hole.

[0076] With reference to Figure 9 , the connecting assembly 6 is a double-headed pull rod, the two pull rods 62 of the double-headed pull rod are connected to the first connecting ring 14 and the second connecting ring 54 respectively, the other ends of the pull rods 62 are in threaded fit with the threaded sleeves 61, the threaded sleeves 61 are screwed to adjust the angle between the rotating rod 51 and the supporting column 11, and the rotating rod 51 and the supporting column 11 are also fixed.

[0077] With reference to Figure 10 and Figure 11For the place where sand prevention and sand fixation is needed, more is large area blocking, therefore. The greening net of the application can be spliced for use, the connecting block 15 is matched and inserted into the connecting frame 16, the parallel greening net belt or the vertical greening net belt is formed, the vertical greening net belt can be used for avoiding obstacles that cannot be operated, and the assembly and layout are carried out in the bypassing mode, when parallel layout is carried out, the two rotating assemblies 5 and the connecting assembly 6 close to each other can be removed (one set is removed), so that the production cost is reduced.

[0078] The embodiment of the application further discloses a use method of the windproof and sand prevention greening net.

[0079] S1, measure the required spacing of the installation support assembly 1, position the drilling point, and clean the sand ground which is greater than the width of the base 18 and is sufficient for the base 18 and the rotating assembly 5 to be laid flat;

[0080] S2, the installation plate 21 provided with the sand prevention net 3 is inserted into the installation groove 123 through the positioning block 23 until the bottom is positioned on the base 18, the positioning block 23 is fixed in the installation groove 123, and the covering net is hooked on the hooks 53 below the two rotating rods 51;

[0081] S3, the output shaft of the screwing device is inserted into the connecting hole 422, the positioning pin on the output shaft of the screwing device is inserted into the positioning groove 425 and selected into the limiting groove 424, the limiting block in the limiting groove 424 is limited, the output shaft of the screwing device is rotated, and then the threaded column 421 is drilled into the sand ground from the drilling point;

[0082] S4, the rotating shaft 52 is placed in the lower groove hole 43, the bolt is screwed through the mounting seat 41 and the fastening hole 423, the mounting seat 41 is fixed with the base 18, the rotating shaft 52 rotates between the upper groove hole 19 and the lower groove hole 43, and at this time, the covering net is attached to the sand ground surface;

[0083] S5, the two pull rods 62 of the double-head pull rod are connected to the first connecting ring 14 and the second connecting ring 54 respectively, the threaded sleeve 61 is screwed, the angle between the rotating rod 51 and the support column 11 is adjusted, the rotating rod 51 is tightly attached to the sand ground at the cleaning position, the covering net is pressed tightly, and the fixing of the rotating rod 51 and the support column 11 is completed;

[0084] S6, the bolt is screwed through the first through hole 17 and the threaded hole, the head of the bolt is clamped on the outer side of the support column 11, the bolt is rotated, the mounting column 121 compresses the elastic piece 122 under the threaded cooperation, so that the spacing between the two mounting assemblies 2 is increased, and then the sand prevention net 3 is tightened again;

[0085] S7, when installing multiple strip-shaped net bodies, the multiple strip-shaped nets with mesh are hung between the two arrays of hooks, the position of the second connecting ring is changed by moving the slider in the strip-shaped sliding slot, then the second connecting ring is rotated, so that the strip-shaped fixed net can be tightened while deflecting a small angle, thereby being able to be adjusted according to the blowing direction of wind and sand.

[0086] Therefore, the rotatable design of the magnetic material hanging ring and the embedded magnetic block of the second connecting ring 54 in the application can install multiple closed nets or strip-shaped fixed nets with different structures, and the strip-shaped fixed net can be flipped and moved when fixed, so that the sand and soil can be moved conveniently. After the multiple strip-shaped nets with mesh are hung between the two arrays of hooks 53, the position of the second connecting ring 54 is changed by moving the slider in the strip-shaped sliding slot, then the second connecting ring 54 is rotated, so that the strip-shaped fixed net can be tightened while deflecting a small angle, thereby being able to be adjusted according to the blowing direction of wind and sand, and achieving a better ground wind prevention and sand fixation effect.
