Corn seeding machine

Abstract

The invention discloses a corn seeding machine, belonging to agricultural machinery. The corn seeding machine comprises a rack, a harrowing plate, a compaction roller, a furrow opener, a film mulching mechanism, a seeding mechanism and a fertilizer application mechanism, wherein the rack is provided with a roller, the harrowing plate, the compaction roller, the furrow opener, the film mulching mechanism, the seeding mechanism and the fertilizer application mechanism; the film mulching mechanism comprises a mulching film support roller and a film spreading roller; the seeding mechanism comprises a seed box, a seed absorber and a seeder; and the fertilizer application mechanism comprises a fertilizer box, a fertilizer application adjusting device and a fertilizer conveying pipe. According to the invention, a seedling release hole formed in a film opener is in a cross shape; and since the seedling release hole cannot be automatically closed, the phenomenon that the seedling is killed since the germinating seedling cannot push up the mulching film can be avoided, and the emergence rate is improved.

Description

technical field [0001] The invention belongs to agricultural machinery, in particular to a corn seeder. Background technique [0002] The Chinese patent publication number is "a novel corn planter" disclosed in CN201612014U, which has the following deficiencies in production practice: [0003] 1. After the seeds are planted in the ground, since the hole opened by the film opener is a slit, the covering film will automatically close, resulting in that the seeds cannot be pushed out of the covering film after germination, resulting in dead seedlings; [0004] 2. The number of seeds sown is generally 2. Especially for small corn varieties, the number of seeds planted is 2 to 4. The waste of seeds is serious. Later management requires thinning, which is time-consuming and labor-intensive; Contents of the invention [0005] In order to avoid above-mentioned phenomenon, the present invention provides a kind of corn sowing machine of single grain sowing. [0006] The invention ...
