Description

TECHNICAL FIELD

[0002] The willow sand barrier is a sand barrier system formed by cutting or weaving with willow branches as the core material in a grid, strip or composite structure, which is widely used in mobile dune control, wind erosion pit repair and plateau wetland protection. Its core principle is to increase the surface roughness by using willow branches to significantly reduce wind speed and reduce wind erosion and sand accumulation. At the same time, the sand barrier provides a stable foothold for plant seeds, improves the microclimate and soil conditions, and promotes natural vegetation restoration. As a native vegetation of sandy land, willow has the characteristics of cold, heat and sand burial resistance, and its branches are easy to reproduce and grow fast, which is highly compatible with the ecology of sandy land and can effectively control wind and sand flow. It is an important means to control desertification.

10. A method for a mechanized laying device based on willow sand barriers, applicable to the mechanized laying device based on willow sand barriers as described in any one of claims 1 to 9, characterized in that, Includes the following steps: Step 1, Laying Preparation: Transport the device to the target area where the yellow willow sand barrier is to be laid, and then check the power of the storage battery (4). If the power is insufficient, use the power generation mechanism (5) to charge it. The power generation mechanism (5) uses the photovoltaic power generation panel (53) to convert solar energy into electrical energy under sunlight conditions. At the same time, the wind turbine (54) converts wind energy into electrical energy when there is wind. The two together replenish the power of the storage battery (4). Check the remaining amount of adhesive in the storage box (21). If it is insufficient, add an appropriate amount of adhesive through the feed pipe (22). Confirm that the curtain-shaped yellow willow bundles (10) and the mesh body (38) are installed correctly and in sufficient quantity. Step 2, Place the yellow willow: Start the telescopic drive assembly (12), and its output end drives the trench opener (13) to move downwards, opening a trench in the sand that meets the paving requirements. At the same time, start the tracked chassis (11) and let the device move slowly along the pre-planned route. As the device moves forward, the curtain-shaped yellow willow bundles (10) on the storage tray (9) gradually unfold under the action of gravity or slight external force, and fall into the opened trench through the guide chute (8) and the guide plate (7). Step 3, spraying binder: Start the pump (23) to deliver the binder in the storage tank (21) to the binder nozzle (25) through the delivery pipe (24). This will allow the binder to be sprayed evenly on the trench and the surrounding sand surface, providing a bonding foundation for subsequent operations. The device continues to move forward, and the covering wheel (28) installed on the lower part of the inner wall on both sides of the adjusting frame (26) covers the surrounding sand in the area where the binder has been sprayed, so that the binder and sand are initially mixed to form a sand layer with a certain degree of adhesion. Step 4, Laying the mesh: As the device continues to move forward, the mesh body (38) on the mesh roll (32) unfolds smoothly under the guidance of the guide roller (39), so that the mesh body (38) covers the surface of the laid yellow willow sand barrier. At this time, the moving drive component (34) drives the moving frame (35) to move downward, so that the pressure roller (36) applies pressure to the mesh body (38) during the movement, inserting it into the sand.
