Figure 4

[0070] It should be noted that, taking the sand barrier formed by the first pressure disc assembly 150 as the first sand barrier row (as shown in Figure 4 , the second pressure disc assembly 170 as the second sand barrier row (as shown in Figure 4 , based on the above content, it can be known that, since the first release frame 131 is fixed to the frame 110, the first sand barrier row is straight, and since the second release frame 133 can move relative to the frame 110, the extending path of the second sand barrier row can be changed during the movement of the frame 110, that is, during the laying of the sand barrier, the extending path of the first sand barrier row is consistent with the movement path of the frame 110, and at this time, the second release frame 133 can move relative to the frame 110, so that the relative position thereof can be changed, so that the distance between the second sand barrier row laid by the second release frame 133 and the first sand barrier row can be adjusted at any time, and the path of the sand barrier laid by the second release frame 133 can be changed, so that the sand barrier laid by the sand fixing machine 100 can form a composite sand barrier group, which can improve the ability of the sand barrier group to reduce wind speed and fix sand surface, and thus improve the sand fixing effect.

[0071] Therefore, please refer to Figures 1-7 , combined with the above content, it can be known that the embodiment adopts the mode of arranging one second pressure disc assembly 170 and two first pressure disc assemblies 150, and the purpose is to form two parallel and straight extending sand barrier rows by the two first pressure disc assemblies 150 and the curved or bent path extending sand barrier row by the second pressure disc assembly 170 under the condition that the second pressure disc assembly 170 and the two first pressure disc assemblies 150 work at the same time, as shown in Figure 4 , and the working state of the aforementioned second pressure disc assembly 170 and the two first pressure disc assemblies 150 can be adjusted according to actual conditions, for example, the two first pressure disc assemblies 150 can be made to work to form two parallel and straight extending sand barrier rows, as shown in Figure 5 , the second pressure disc assembly 170 can form a curved or bent path extending sand barrier row, as shown in Figure 6 , one of the first pressure disc assemblies 150 can be made to work to form a straight extending sand barrier row, as shown in​Figure 7 as shown.
