Technical Field
[0001] The utility model belongs to the technical field of desertification prevention and control equipment, and particularly relates to a mesh sand barrier paving machine. Background Art
[0002] my country faces a severe desertification situation, with approximately 400 million people affected by desertification. Sand barriers are the most commonly used and effective technical measure in sand control and sand fixation projects, playing a particularly important role in managing shifting sand and restoring vegetation. Currently, the main types of sand barriers in use include biological, mechanical, and mesh sand barriers. These barriers primarily use materials such as firewood, grass, branches, and slats inserted directly into the sand surface, or clay, pebbles, and other materials piled up to form ridges on the sand surface, which reduce wind speed and block and stabilize shifting sand. Common sand fixation measures include grass grids, branch sand barriers, sand fences, clay grids, gravel grids, and clay burials. However, a common problem with these various types of sand barriers is the inability to effectively control the depth of the concave surfaces formed by wind erosion between the barriers, which in turn affects the survival and preservation rates of afforestation within the barriers.
[0003] A new type of sand barrier with mesh has been developed to address the concave depth caused by wind erosion, effectively improving afforestation success and preservation rates. However, the manual installation of these barriers is labor-intensive, slow, inefficient, and costly, leading to a pressing need to significantly reduce the cost of installing these barriers. Furthermore, if these barriers are manually installed with mesh sand barriers, problems such as shallow penetration depth and gap leakage can easily lead to wind erosion and erosion, ultimately resulting in the failure of the barrier project.
[0004] Existing sand barrier installation machines are susceptible to the effects of terrain fluctuations during construction, resulting in inconsistent buried depths and large variations in exposed surface heights. This can lead to sand burial or erosion, significantly impacting the effectiveness of the sand barrier and, in severe cases, rendering it ineffective and potentially causing the project to fail. Therefore, a mesh sand barrier installation machine was developed to address this critical issue. Utility Model Content

A mounting plate 8 is provided, on which a first screw 9 is fixedly installed by bolts, a sand accumulation wheel 10 is fixedly connected to the bottom end of the first screw 9, and the sand accumulation wheel 10 is installed at an angle to facilitate the gathering of sand. The sand accumulation wheel 10 is disc-shaped, with a thickness of 0.6 cm and a radius of 10 cm. The bottom of the sand accumulation wheel 10 is slightly lower than the bottom of the sand bucket 6 by 3 cm. Two second screws 11 are fixedly installed at the end of the frame 1 by bolts, and a compacting wheel 12 is fixedly connected to the bottom end of the second screw 11, with a thickness of 5 cm and a radius of 10 cm. A three-point suspension device is fixedly installed on the frame 1 for connecting the device to the rear of a tractor and moving the device by the tractor.
[0028] The sand barrier mesh is released from the storage roller 3. The pressing wheel 5 presses the center of the barrier mesh into the sand, forming a U-shape, or nearly U-shape, in the middle. The sand accumulation wheel 10 gathers the sand, which enters the sand storage bucket 6. Under the influence of the guide ribs 7 and gravity, the sand enters the sand barrier mesh. Finally, the compacting wheel 12 presses the soil on both sides of the sand barrier into the sand ditch, reducing the distance between the two sides of the sand barrier and increasing its effectiveness and service life.
[0029] In this embodiment, a guide roller 15 is rotatably installed on the frame 1. The guide roller 15 is located between the material storage rack 2 and the pressing wheel 5. The guide roller 15 guides the mesh sand barrier to the bottom of the pressing wheel 5, reducing the friction between the frame 1 and the loss of sand barrier material.
[0030] In this embodiment, two rotating shafts 4 are rotatably installed in the middle position of the frame 1, and the inner ends of the rotating shafts 4 are fixedly installed with mounting steel plates 13. The pressing wheel 5 is fixedly installed between the mounting steel plates 13 by bolts, which facilitates the replacement and maintenance of the pressing wheel 5.
[0031] In this embodiment, the pressing wheel 5 is made of twenty-two arc-shaped steel plates spliced together. A single arc-shaped steel plate is 20 cm long, 5.5 cm high and 6 cm wide at the inner edge, 4.8 cm high and 12 cm wide at the outer edge. The two ends of the arc-shaped steel plate are symmetrical and gradually shrink and narrow from the outside to the inside. The edge of the pressing wheel 5 is a continuous S-shape, so that the two ends of the net-type sand barrier pressed into the sand are lifted up and form strip-shaped vertical folds.
[0032] In this embodiment, a protective cover 14 is fixedly installed on the frame 1. The protective cover 14 is located above the pressing wheel 5 to prevent danger to workers when installing sand barrier materials.
[0033] When in use, the device is connected to the rear of a 50 horsepower crawler tractor through a three-point hitch.
[0034] Before the operation, the height of the tractor suspension system is pre-adjusted according to the surface conditions of the dune terrain so that the main part of the frame is roughly parallel to the dune surface, the sand barrier material is installed on the storage roller 3, and then the storage roller 3 is installed on the storage rack 2.
[0035] During the trial operation, at the actual sand dune operation site, the crawler tractor uses a low speed gear to pre-check the effect of laying the net sand barrier according to the requirements of laying the net sand barrier.
[0036] After completing the above inspection and operation, the tractor travels at a constant speed so that the whole machine moves at a constant speed with the tractor and enters the working state of loosening sand.
[0037] At the same time, manpower spreads a section of net sand barrier on the sand surface in front of the compacting wheel 12. Under the dual effects of the gravity of the compacting wheel 12 and the tractor's uniform forward movement, the net sand barrier is fixed, and the material storage roller 3 on the material storage 2 rotates to continue releasing the sand barrier material.
[0038] The sand barrier mesh is released from the stocking roller 3. The pressing wheel 5 presses the center of the barrier mesh into the sand, forming a U-shape, or nearly U-shape, at either end. The sand barrier mesh, pressed into the sand, rises and stands upright, forming strips of vertical folds. The sand accumulation wheel 10 gathers the sand, which enters the sand accumulation bucket 6. Guide ribs 7 and gravity force the sand into the barrier mesh. Finally, the compacting wheel 12 presses the soil on both sides of the barrier into the sand ditch, reducing the distance between the two sides and increasing the barrier's effectiveness and lifespan.
[0039] When the net-type sand barrier material on the storage roller 3 is used up, the operation is stopped, and the sand barrier material is loaded on the second storage roller 3. At the same time, the net-type sand barrier material is installed on the first storage roller 3 and placed on the storage rack, and the above operation is repeated.
[0040] After the net sand barrier is laid, the tractor hydraulic suspension device lifts the entire machine and transports it back to the storage location.
[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent variation of the above embodiment made according to the technical essence of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
