背景技术 Background technique

播种作为农业生产最重要、最基本的生产环节,其作业质量对农作物的发芽出苗有着重要的影响。传统上为了保证播种深度和镇压强度的一致性,都是采用加设仿形机构的结构保证播种深度的一致性,但是实践证明开沟深度即使一致,但是由于种子的弹跳导致种子下落点存在很大的随机性,加之后续覆土量的影响,很难保证播种深度的一致性要求,该问题对于当前推行的保护性耕作更为突出。其次,由于种子着床存在弹跳影响,所以也很难保证种子与种床湿土的接触,进而影响种子的发芽和幼苗出土的一致性。为此,加强播种深度一致性和确保种子与种床湿土接触的技术研究就显得非常重要。 Sowing is the most important and basic production link in agricultural production, and its operation quality has an important impact on the germination and emergence of crops. Traditionally, in order to ensure the consistency of the sowing depth and the suppression intensity, the structure of adding a profiling mechanism is used to ensure the consistency of the sowing depth. However, practice has proved that even if the trenching depth is the same, there are differences in the whereabouts of the seeds due to the bouncing of the seeds. Due to the large randomness and the influence of the amount of subsequent covering soil, it is difficult to ensure the consistency of the sowing depth. This problem is more prominent for the current conservation tillage. Secondly, due to the bouncing effect of seed implantation, it is also difficult to ensure that the seeds are in contact with the wet soil of the seed bed, which in turn affects the germination of seeds and the consistency of seedling emergence. For this reason, it is very important to strengthen the technical research on the uniformity of sowing depth and ensure that the seeds are in contact with the wet soil of the seedbed.

When working, the ditch opener 1 is first used to open a seed ditch on the ground surface. When the seeds randomly fall on the ditch opened by the ditch opener 1, the seeds are tightly pressed on the seed bed by the seed pressing wheel 10, realizing the separation between the seeds and the seed ditch. Close contact with wet soil in the seedbed. In this process, due to the effect of the upper limit depth ring of the seed pressure wheel 10, the consistency of the seed sowing depth is guaranteed; then the trapezoidal window 15 at the rear of the opener 1 leaks into the wet soil, so that the upper and lower surfaces of the seeds are covered by the wet soil. Surrounded by it, the germination rate of the seeds is guaranteed. Since the seed pressing wheel 10 is a low-pressure pneumatic wheel 13, the clay on its surface can be removed along with the deformation of the outer surface of the low-pressure pneumatic wheel 13; The secondary suppression of the seed belt after covering the soil completes the entire sowing process.
