Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a soil cutter. Background Art

[0002] In agricultural production, before planting watermelons or other crops in greenhouses, it is necessary to build a greenhouse environment in the field. When building a greenhouse, first of all, the land should be divided and regularized according to the area of ​​the greenhouse. Especially for hardened land, it is necessary to cut the soil so that the steel pipes used for supporting the greenhouse on both sides can be smoothly inserted into the land. Then, the cut soil is filled on the film extending to the ground on both sides of the greenhouse to ensure the convenience and stability of the greenhouse installation.
