Description

Technical Field

[0001] The utility model relates to the technical field of seed drills, in particular to a double-soil-covered and film-laid seed drill. Background Art

[0002] In agricultural production, the demand for water for crops is crucial. In some areas, irrigation has become a difficult problem and they can only rely on natural precipitation. The film-covered sowing model makes full use of the small amount of precipitation.

[0003] The existing device does not cover the soil at one time, but only installs a disc on the side of the seeding drum to press the film. Seeds are seeded synchronously during the film pressing process. The ground film has a certain ductility when it is laid. The ground film is pressed down empty and the soil is buried at the back. The ground film shrinks due to its ductility, and the holes are displaced synchronously, resulting in the seedlings having to be manually pressed after germination. During the germination process, the seedlings cannot come out and will cause the seedlings to die. In addition, the previous discs cannot effectively seed when there are stones, stubble, etc. in the ground. Foreign objects such as stones and stubble falling into the film groove will raise the film pressing disc, resulting in the duckbill on the seeding drum being unable to make holes in the ground film. The seeds will fall on the ground film and cannot take root in the soil. Utility Model Content
