Description

Technical Field

[0001] The utility model relates to the technical field of desertification prevention and control equipment, and specifically to a curtain-shaped sand barrier paving machine. Background Art

[0002] Laying sand barriers is an effective measure to combat desertification. In large areas of desertification, such as deserts and sandy lands, these barriers are laid on the surface of shifting sand in strips or grids, along dune contours or perpendicular to the prevailing wind direction. The height, air permeability, and configuration of the sand barriers are crucial structural parameters for their protection range and effectiveness. Factors such as the slope of the pre-installed sand barrier area, wind intensity, and the number and direction of the dominant winds directly determine the selection of structural parameters such as the sand barrier's size, specifications, and configuration.

[0003] Sand barriers are generally categorized by height into high-standing, low-standing, and flat-lay types. High-standing sand barriers are primarily fixed to the surface by direct erection or burial, typically protruding at least 50 cm above the ground. Low-standing sand barriers are often buried, typically protruding between 20 and 50 cm above the ground. Flat-lay sand barriers are fixed to the surface by placement or burial, typically protruding less than 20 cm above the ground. Sand barriers that are almost entirely buried in the soil, with only a slight top exposure, are also known as concealed sand barriers. Curtain-style sand barriers, which can be configured as low-standing or flat-lay types, are a common sand barrier method used in sand control and prevention projects. Currently, these sand barriers are manually laid. A trench is dug on the dune surface, and the curtain-like sand barrier is manually inserted into the trench. Soil is added to the sides and compacted by foot. The material is then gradually laid along the trench. When the material is used up, the barrier strip is laid, continuing along the trench until it is complete.

[0004] Driven by the implementation and promotion of the "Three Norths" project and the landmark campaign to combat desertification, the research and development of sand control machinery has entered a critical period, and the development of sand barrier machinery is urgently needed. Mechanical sand control technologies not only ensure effective sand control but also improve operational efficiency and reduce costs. The development and use of sand barrier machinery will significantly accelerate the progress of desertification control. Currently, with the increasing precision of sand control tasks, a large number of efficient and convenient sand fixation and afforestation machinery have been invented, but most of them focus on machines for setting grass grid sand barriers, and no reports have been made on other types of sand barrier laying machinery. Curtain-type sand barriers offer many advantages, such as easy material availability, strong protection, long-term protection, and simple installation principles. However, manual installation is slow and inefficient, resulting in high costs. Therefore, there is an urgent need to develop supporting curtain-type sand barrier laying machinery to address the practical problems encountered in manual installation. Utility Model Content

A plurality of groups of mounting studs 6 are vertically fixedly connected to the frame 1, and the mounting studs 6 are located on the outside of the mounting steel plate 4. A material-smoothing steel plate 7 is fixedly connected to the mounting studs 6, and the material-smoothing steel plate 7 is inclined toward the rear end of the frame 1, pressing down the curtain-like sand barrier. A pressing stud 8 is fixedly installed on the outside of the top of the rear end of the mounting steel plate 4, and a pressing plate 9 is fixedly connected to the top of the pressing stud 8. A compacting device is provided at the rear end of the mounting steel plate 4, and a three-point suspension device is provided on the frame 1. The device can be fixedly connected to the rear of a tractor through the three-point suspension device, and the device can be moved by towing the tractor.

[0028] The furrowing plow 5 digs a ditch on the sand dune, and the curtain-like sand barrier enters the ditch from between the mounting steel plates 4. The pressing plate 8 can press the curtain-like sand barrier into the ditch, and the curtain-like sand barrier is compacted by the compacting device.

[0029] In this embodiment, a vibration motor 10 is fixedly mounted on the top of the pressing plate 9. Two mounting nuts 11 are threadedly connected to the pressing stud 8. The pressing plate 9 is located between the two mounting nuts 11. A base nut 12 is threadedly connected to the pressing stud 8. A spring 13 is provided between the mounting nut 11 and the base nut 12 at the bottom. The spring 13 is sleeved on the pressing stud 8. When the vibration motor 9 is in operation, it vibrates the pressing plate 8, causing it to press the curtain-like sand barrier into the ditch.

[0030] By adjusting the positions of the two mounting nuts 11, the height of the pressing plate 9 can be adjusted, thereby controlling the depth of the sand barrier.

[0031] In this embodiment, a gasket is provided between the mounting nut 11 and the smoothing steel plate 7 , and gaskets are also provided on both sides of the spring 13 to increase the contact area and prevent loosening.
