Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a seed drill roller device. Background Art

[0002] The air suction drum seeder uses vacuum negative pressure technology to achieve negative pressure seed suction. After the drum turns to the sowing position, the negative pressure is disconnected to allow the seeds to fall into the hole tray to complete the sowing action.

[0003] However, seeds contain seed coats and dust, and the seed drill will also suck in the seed coats and dust while sucking the seeds. Over time, the seed coats and dust will block the seed suction holes, affecting the sowing accuracy. At present, the seed suction holes are mostly unblocked by manual operation, but the above operation is relatively cumbersome and affects the sowing efficiency. Therefore, an anti-blocking technology is urgently needed to ensure sowing accuracy. Utility Model Content
