Description

Technical Field

[0001] The utility model relates to the technical field of seeding devices, in particular to a precise rape seeding device. Background Technique

[0002] Rape seeds are rich in rapeseed oil with a high oil yield, and the cake residue after oil extraction is also rich in various nutrients and can be used as fertilizer and feed. A seeding machine is a planting machine with crop seeds as the seeding object, which has a high degree of automation, greatly saves labor intensity and improves seeding efficiency. Rape seeds are small in volume and strong in fluidity. When sowing rape, the methods of broadcasting and drilling are usually adopted, which easily causes a large amount of seed consumption and serious waste, with high labor intensity, high labor consumption and low efficiency.

Through the cooperation of a frame, a material cylinder rotating shaft, a plurality of seeding rotating barrels, a driving mechanism, a traveling mechanism and a ditching mechanism, the invention can realize the precise and visual seeding of rape seeds; during the rotation of the seeding rotating barrel, the seeds therein always remain in a loose state, which can reduce the possibility of blocking the through holes of the seed dropping groove, and the seed dropping groove is constantly repeated in the upward and downward processes, which can also reduce the possibility of blocking the through holes of the seed dropping groove, making the seeding more accurate. At least part of the structure of the seeding rotating barrel is a transparent structure, so that the operator can see the situation therein from the outside, so as to timely carry out dredging maintenance and adjust the seeding plan, which is beneficial to uniform seeding.
