Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and in particular to a soil covering operation device. Background Art

[0002] In agricultural planting in arid areas, mulch planting has been widely used. After laying the film, it is generally necessary to cover the soil. Especially with the current application of film-based spot planting technology, it is often necessary to cover the soil after the seedlings emerge.

[0003] Existing soil covering machines are mainly drum-type soil covering equipment, which puts soil from both ends of the soil covering drum into the soil covering drum through a soil cutting mechanism, and spits out the soil from the soil outlet in the middle of the soil covering drum to cover the seedling row. When this type of soil covering machine is in operation, the soil covering drum will cause damage to the already germinated crop seedlings, and in the current precision agriculture, this damage often has a very large impact on the overall crop.

[0004] Therefore, a soil covering device suitable for covering the crops after they have emerged and which does not affect the crop seedlings is proposed. Summary of the invention
