Current devices, systems and methods use air pressure to provide seeds to the earth in a controlled manner. In some form of completion, a valve is activated to push a seed outside the seed chamber. Seeds can be transferred to the southwest at a high speed in the salt room and seed supply device. If you are already registered, please log in first.A with precisely controlled air pulses, changes in known supply and dose technologies can be eliminated, and seeding speeds can be increased. 1. Claim 1: a device for dosing seeds on an agricultural seeder, including: (a) accommodation(b) A seed chamber defined in the residence, wherein the seed chamber comprises: (1) a seed transmitting position configured for continuous receiving of seeds； (2) a seed spraying port for smooth communication with the seed transmitting position； (c) A seed receiving hole determined in a residence with smooth communication with the seed chamber, where the seed receiving hole is adjacent to the seed launching position； (d) an air pulse source related to the residence；The air pulse generator includes: (1) a pressurized air source； (2) a repetitive air pulse generator combined with the pressurized air source. The air pulse generator has smooth communication with the seed chamber.Los dispositivos, sistemas y métodos de la presente utilizan una presión de aire para suministrar semillas en la tierra de manera controlada. En ciertas formas de realización, se acciona una válvula para empujar una única semilla hacia afuera de una cámara de semillas. La semilla puede ser trasladada desde el alojamiento dosificador y a través de un aparato de suministro de semillas hacia el surco a una velocidad elevada. El traslado rápido desde la cámara de semillas hacia el surco mediante el impulso de aire controlado en forma precisa elimina la variación de las tecnologías de suministro y dosificación conocidas y permite mayores velocidades de siembra. Reivindicación 1: Un aparato para dosificar semillas en una sembrad
