Description

Technical Field

[0001] This utility model relates to the field of land reclamation construction technology, and in particular to a rapidly movable ramp device for descending into fields. Background Technology

[0002] Conventional field access ramps are constructed by disrupting the field ridges, backfilling with earth and stone, and compacting the soil to facilitate equipment movement. However, due to the relatively crude construction method, excavators are needed to destroy the original field ridge structure and create temporary passages through earthwork excavation and backfilling. The height of the field ridges is not scientifically measured and designed, resulting in a low degree of matching between the ramp height and the needs of agricultural machinery.

[0003] Meanwhile, directly damaging the field ridges increases the risk of soil erosion in farmland. The compacted soil and rock are difficult to restore the original topsoil structure. Furthermore, fixed ramps cannot be flexibly adjusted according to the height of the field ridges. Each time construction or agricultural equipment enters the site, excavators are needed for repairs, which is time-consuming and labor-intensive. Temporary fill is easily affected by rain erosion or agricultural machinery rolling, which can easily lead to problems such as collapse and slippage, requiring periodic maintenance.

[0004] Chinese patent document CN 115627672 A describes a field ramp device for agricultural machinery. This field ramp device is relatively complex, occupies a large space, and has defects in use, requiring improvement. Utility Model Content
