Pneumatic onion seed drill is a kind of agricultural machinery that uses the principle of negative pressure suction to precisely sow onion seeds to a predetermined position. Its main features include high precision, high efficiency, easy operation, and it is suitable for large-area onion planting.China Qingdao Dashun is committed to research and development of pneumatic onion seed drill, which can achieve precision sowing of one seed in one hole, and the rate of sowing single seed is as high as 97%.

Working Principle:
Pneumatic seed drill generates negative pressure by fan rotation, adsorbs the seeds and transports them to the sowing pipe. When the sowing pipe reaches the specified position, the airflow stops and the seeds fall into the soil under the effect of gravity to achieve precise sowing.
Main features:
– Precise sowing: Adopting air suction technology ensures one or more seeds in each hole, avoiding leakage or re-sowing and improving seedling emergence rate.
– Wide range of application: it can sow many kinds of small seeds, such as onion, carrot, beet, rape, parsley, spinach, celery and so on.
– Simple operation: reasonable structure design, easy to adjust and maintain, suitable for farms of different sizes.
A pneumaic onion seed drill not only reduces labour costs it also reduces seed costs and saves time, a pneumatic onion seed drill is also a pneumatic carrot seed drill and a pneumatic beet seed drill.
