Description

Technical Field

[0001] This utility model relates to the field of geomembrane laying technology, and in particular to a geomembrane laying device for landfills. Background Technology

[0002] The standard name for geomembrane is polyethylene geomembrane, which is mainly a milky white, semi-transparent to opaque thermoplastic resin material. Made from polyethylene resin, polyethylene is a high molecular weight polymer that is a non-toxic, tasteless, and odorless white granule with a melting point of approximately 110℃. At 130℃, with a relative density of 0.918-0.965, geomembranes exhibit good heat and cold resistance, good chemical stability, high rigidity and toughness, good mechanical strength, and good resistance to environmental stress cracking and tear strength. As the density increases, the mechanical properties and barrier properties will improve accordingly, and the heat resistance and tensile strength will also be higher. They are resistant to corrosion from acids, alkalis, organic solvents, etc.

[0003] However, the traditional method of laying geomembranes mostly relies on manual labor, which requires the assistance of many people and the transportation of the geomembrane. This not only consumes a lot of manpower but also delays the construction period and causes unnecessary losses. Its use is quite limited. Although there are now geomembrane laying devices, their functions are relatively simple, which brings great inconvenience to the users. Utility Model Content

The unwinding mechanism 3, pressing mechanism 4, cutting mechanism 5, and guiding mechanism 6 are mounted on the upper surface of the vehicle body 1. The traction mechanism 2 and swing roller mechanism 7 are respectively mounted on both sides of the vehicle body 1. An external power device can be connected and installed to the traction mechanism 2, thereby pulling the landfill geomembrane to move the geomembrane. The landfill geomembrane laying device moves to achieve a pulling effect. The geomembrane roll is installed on the unwinding mechanism 3. The unwinding mechanism 3 unwinds the geomembrane and passes it through the pressing mechanism 4, the cutting mechanism 5 and the guiding mechanism 6 in sequence to the swing roller mechanism 7. The vehicle body 1 is equipped with pressure rollers 11. The two pressure rollers 11 are rotatably set at the lower end of the vehicle body 1 to support the movement of the vehicle body 1. During the pulling process of the vehicle body 1, the landfill soil is compacted by the pressure rollers 11 to keep the ground flat. The swing roller mechanism 7 presses the geomembrane tightly onto the ground and keeps it close to the ground to prevent the geomembrane from lifting due to uneven ground, thus failing to achieve the purpose of seepage prevention. Specifically, the vehicle body 1 is also equipped with a battery and a control system. The battery provides power to the unwinding mechanism 3, the pressing mechanism 4, the cutting mechanism 5, and the swing roller mechanism 7.

[0021] The pressing mechanism 4 includes a pressing bracket 41, a pressing structure 42, and a pressing base 43. The pressing structure 42 is mounted on the pressing bracket 41, and the pressing bracket 41 has a pressing channel 411 through which the geomembrane can pass.

The heating wire 513 is mounted on the cutting blade holder 512, and the cutting cylinder 511 is mounted on the cutting bracket 52. The cutting cylinder 511 drives the cutting blade holder 512 to move, thereby moving the heating wire 513 to cut the geomembrane by thermal cutting. Specifically, the cutting blade holder 512 is made of heat-insulating material. When the pressing cylinder 421 drives the pressing plate 422 to move closer to the pressing base 43, pressing the geomembrane between the pressing plate 422 and the pressing base 43, the cutting cylinder 511 drives the cutting blade holder 512 to move, moving the heating wire 513 to contact the geomembrane, thereby cutting the geomembrane.

[0023] The guiding mechanism 6 includes a guiding bracket 62 and a guiding roller 61. The guiding roller 61 is rotatably mounted on the guiding bracket 62 to support the geomembrane and guide the geomembrane to the swing roller mechanism 7.
