Peanut mulching punching-free seeding machine and method

The invention relates to a peanut mulching punching-free seeding machine and method, and belongs to the technical field of agricultural machinery type peanut seeding machinery. According to the technical scheme, a soil separating and film burying device (14) pushes surface soil into an outer barrel (52) of an on-film soil covering device (15) in the advancing process, the on-film soil covering device rotates, the surface soil in the outer barrel (52) is moved to the position between the outer barrel (52) and an inner barrel (53) to be leaked and fall on a mulching film above sown peanut seeds, protection is provided for film breaking growth of peanut seedlings while the mulching film is pressed, the peanut seedlings are prevented from being burnt by too high temperature under the film, and punching-free operation after peanut film mulching is achieved. The peanut mulching punching-free seeding machine and method have the beneficial effects that after ridging, sowing and film mulching are conducted, soil cover
