Description

Technical Field

[0001] This utility model relates to the technical field of turf stripping devices, and more particularly to a turf cutting device for high-altitude areas. Background Technology

[0002] In the construction of high-altitude wind power projects, turf cutting and stripping is a preliminary process for foundation construction. High-altitude turf has a long growth cycle and high ecological fragility, so it is necessary to preserve the integrity of the turf to the greatest extent possible to facilitate later transplantation and restoration. Traditional processes rely on manual cutting of turf, which leads to low construction efficiency. The spacing and depth of manually cut turf cannot be kept consistent, resulting in incomplete stripping or turf breakage during the stripping process. This makes it impossible to preserve the turf neatly and makes it difficult to meet the needs of large-scale projects.

[0003] In the existing technology, conventional turf stripping equipment has the following defects: the blade structure is fixed, which is a fixed rectangular or circular blade head. It needs to cut one area up and down to complete one area, and then move to the next area to cut up and down again. It cannot continuously complete the turf cutting operation, resulting in low efficiency. Utility Model Content
