Abstract

The invention relates to a seeder, in particular to a thinning-free accurate seeder applicable to cereal seeding, solving the technical problem of seeds germination percentage influenced by simple designs of the existing seeders during quantitative seeding. The thinning-free accurate seeder comprises a frame. A depth limiting wheel is arranged at the front of the frame. A seed pressing wheel is arranged at the back of the frame. The middle part of the frame is provided with a material box. A soil covering device is arranged behind the seed pressing wheel. The material box is divided into a seed loading box and a fertilizer loading box. The lower part of the material box is provided with a seed and fertilizer discharging device. The seed and fertilizer discharging device is linked with a shaft of the seed pressing wheel by a transmission. The seed and fertilizer discharging device is respectively communicated with the seed loading box and the fertilizer loading box. The lower part of the frame is provided with a ditching soil-expanding device. The front side of the ditching soil-expanding device is provided with a pointed shovel which is arranged in a downwardly-oblique direction. Two sides of the ditching soil-expanding device are provided with soil blocking plates. Wet soil forced inlets are arranged at the back parts of the soil blocking plates. The thinning-free accurate seeder realizes high germination percentage and high soil water utilization rate. In addition, no seeding ditches are formed after the seeding and soil hardening does not easily take place after raining,therefore, the risk of seedling shortage caused by raining is effectively reduced.

Description

technical field [0001] The invention relates to a seeding machine, in particular to a thinning-free precision seeding machine suitable for sowing grains. Background technique [0002] At present, in the process of planting millet and other crops, sowing has been mechanized, and there are many types of seeders. But the design of the planting mechanism of the traditional seeder is all relatively simple, and its task is to leak the seeds into the soil. The amount of seeds cannot be accurately controlled, so that the number of crop seedlings is relatively large after they grow out, and the seedlings must be thinned. At present, thinning still needs manual operation, which is time-consuming, labor-intensive and labor-intensive. Sometimes the production of barren seedlings is reduced due to untimely thinning. [0003] Difficulty in thinning is a prominent contradiction restricting the development of millet industrialization. Not thinning millet after sowing has always been the ...
