Needle list Seed nozzle

The above seed suction nozzle models are widely used in various types of air-suction automatic seeding equipment. According to the shape and particle size of different seeds, carefully matching the nozzle model is the key to confirming the seeding efficiency and accuracy. During the sowing process, the size of the aperture directly affects the adsorption stability and shedding speed of the seeds. Therefore, in actual operations, the technical selection should be combined with the diameter, weight and surface structure of the seeds.

In order to improve the sowing accuracy and the uniformity of crop germination, the seeds should be screened and processed before sowing to avoid broken or sticky seeds affecting the adsorption efficiency. The needles of various models in the table are made of precision stainless steel materials with good performance and corrosion resistance, suitable for long-term and high-frequency use. Depending on the type of seed, a single-hole or multi-hole suction head structure can be selected to meet the needs of single-seed sowing or intensive sowing.

At the same time, it is recommended that users regularly clean and maintain the seed suction nozzle, especially after sowing seeds with high sugar content or adhesion, it is necessary to rinse with warm water or alcohol solution in time to prevent the orifice from being blocked and affecting the operation. For the 0.26mm (No. 27) and 0.33mm (No. 23) models that are prone to clogging, it is recommended to use a fine filter device to confirm that the air supply system is clean and unobstructed.

The replacement of the seed suction nozzle is easy to operate. It is recommended to switch to the corresponding model in time when changing the sowing operation of different crops, and conduct a trial suction test before starting the equipment to confirm that the adsorption is stable before batch operation. At the same time, in order to meet the diversified needs of modern seedling cultivation, some models also support customized apertures and lengths to adapt to the sowing requirements of special seeds or special-shaped plug trays.

In general, by selecting the seed suction nozzle model through technology and combining it with fine sowing equipment, the sowing quality can be improved and the missed sowing rate can be reduced, thus laying a solid foundation for the subsequent uniformity of seedling cultivation and the commercial seedling rate.
