This utility model provides a directional seeder for Yunnan saffron seeds. The directional seeder includes: a hopper for storing Yunnan saffron seeds; a housing with a discharge cylinder installed at the bottom of the hopper; a support shaft rotatably installed within the housing; and a limiting plate movably sleeved on the support shaft. The limiting plate has a limiting opening for isolating Yunnan saffron seeds to achieve directional sowing of single or double seeds. A rubber sheet for adjusting the size of the limiting opening is adhered inside the limiting opening. This directional seeder for Yunnan saffron seeds, by providing a limiting opening on the limiting plate and adjusting the size of the rubber sheet attached inside the limiting opening, achieves directional sowing of single or double seeds, meeting the needs of Yunnan saffron root sowing for adjusting seed yield.

A saffron stem extractor device is provided. The device is comprised of a saffron stem extractor device designed to facilitate the harvesting of saffron stems from crocus flowers while the flowers remain attached to their bulbs. The device comprises a cutting mechanism configured to sever saffron stems with minimal disruption, wherein the cutting mechanism may include a laser system directed by at least one redirecting element such as a mirror or optical scanner, or a mechanical blade system adapted to various cutting geometries. A vacuum tube composed of a transparent material is used to encase the saffron stems prior to cutting, while a vacuum motor generates negative pressure to extract the severed threads into a collection chamber. A viewing element such as a digital camera or optical magnifier is included for precise visual targeting and is wirelessly linked to a smart device mounted to the apparatus for real-time imaging feedback.

This utility model provides an automatic drip irrigation device for a saffron seedling base. The automatic drip irrigation device for a saffron seedling base includes: a water pump for drawing irrigation water; a drain pipe installed at the pump's discharge end for conveying irrigation water; an extension pipe detachably installed on the drain pipe to expand the drip irrigation range; a first drip head body and a second drip head body installed on the drain pipe and the extension pipe for outputting irrigation water; and a filter mechanism installed at the pump's inlet end for filtering the irrigation water to prevent clogging of the first drip head body. The automatic drip irrigation device for a saffron seedling base provided by this utility model, by connecting the drip tube and the drain pipe with a connecting sleeve, not only facilitates the installation of the first drip head body but also facilitates the replacement of the drip tube without damaging the drain pipe during replacement, effectively preventing leakage.
