[0002] The dust-proof green curtain is an environmental protection material for controlling the dust pollution of open-air stockyards. With the increase of construction sites in the city, when the construction site is close to residential areas, due to a large amount of dust on the construction site, it will have a great impact on the construction site and the surrounding environment. Therefore, it is necessary to lay dust-proof nets on some severely polluted construction earthworks to inhibit the flying of dust.

[0003] A dust-proof net laying device for the foundation earthwork of a construction project disclosed in the Chinese Patent Application Publication Specification CN220434238U. In this utility model, when in use, the elastic components are arranged to make the laid dust-proof net can be attached to the surface of the foundation earthwork, and the cleaning components are arranged to clean the dust on the surface of the dust-proof net, and the adjusting components are arranged to adjust the laying angle of the dust-proof net, so as to meet the laying requirements of foundation earthworks with different slopes.

[0004] Although the above patent solution can adjust the laying angle of the dust-proof net, the laying device in the above patent only controls the distance between the dust-proof green curtain and the ground through the roller during operation, and it is easy to cause the dust-proof green curtain to be blown up when laying in a windy environment, which is not convenient for fixing the two sides of the dust-proof green curtain during laying; for this reason, we provide a dust-proof green curtain laying device for construction engineering to solve the above problems.

[0027] In the above solution, through the cooperative design between the first limiting rod 602 and the second limiting frame 607, the distance and angle between the laid green cloth and the ground can be adjusted.

[0028] Please refer to Figure 3 , the first power mechanism 6 includes a first moving plate 603 rotatably sleeved at one end of the first limiting rod 602 and an arc-shaped groove 601 opened on one side surface of the support frame 1. A first chute 604 is opened on the side surface of the first moving plate 603 away from the first limiting rod 602. One end of the first moving plate 603 away from the first limiting rod 602 is fixedly sleeved with a connecting rod 605 slidably arranged inside the arc-shaped groove 601.

[0031] Please refer to with emphasis Figure 3 , the first power mechanism 6 further includes a first motor 610 fixed to one side of the support frame 1. A transmission rod 611 is fixed to the output end of the first motor 610. A moving shaft 612 is fixedly sleeved at the end of the transmission rod 611 away from the first motor 610. The end of the moving shaft 612 away from the transmission rod 611 is slidably connected to the inside of the first chute 604.

[0032] In the above solution, the first motor 610 drives the transmission rod 611 to rotate. Through the cooperation among the transmission rod 611, the moving shaft 612 and the first moving plate 603, the connecting rod 605 and the connecting plate 606 can be moved, and the second limiting frame 607 can be driven to move, so that the laid green cloth is close to the ground, facilitating the adjustment of the distance between the green cloth and the ground.

Then, through the connecting rod 605 and the connecting plate 606, adjust the height of the second limiting frame 607 to support the green cloth, so that the laid green cloth is close to the ground. After the operating height of the second limiting frame 607 is adjusted, rotate the bolt 609 externally to move the bolt 609 out of the positioning hole 608, and rotate the connecting plate 606 externally to facilitate adjusting the supporting angle of the second limiting frame 607 for the green cloth. After the adjustment is completed, rotate the bolt 609 in the reverse direction to make the bottom end of the bolt 609 embed inside the positioning hole 608, and fix the connecting plate 606 and the connecting rod 605. While the connecting rod 605 is moving, through the cooperation between the connecting rod 605, the second moving plate 73 and the second sliding groove 74, the connecting frame 78 and the limiting block 72 can slide inside the limiting groove 71, and the operating height of the pressing wheel 77 can be adjusted simultaneously, so that the height of the pressing wheel 77 is lower than the height of the second limiting frame 607. Then, through the cooperation between the second motor 75 and the rotating rod 76, the pressing wheel 77 can press both sides of the laid green cloth, and make the green cloth contact the ground, which is convenient for fixing the laid green cloth.
