摘要:
FIELD: agriculture.SUBSTANCE: agricultural machine comprises at least one sowing unit, the seed metering device with seed metering element (803) with a drive device and a chamber for seeds, and a pipeline (812) for dispensing seeds. The chamber is made with the ability of injecting into it of the positive pressure from the pressurizing unit. The seed metering element (803) forms a wall with holes or slots (804) limiting the chamber. The holes/slots (804) connect the chamber with the surrounding environment to create the pressure difference for attachment and movement of the seeds to them. The inlet opening (814) of the pipeline (812) for dispensing seeds is located in the chamber without coming into contact with the side carrying seeds of the seed metering element (803) directly opposite the means (808) of equalizing pressure located on the opposite side to the side carrying seeds of the seed metering element (803). The inlet opening (814) of the pipeline for dispensing seeds is located in close proximity to the receiving region (818) on the side carrying seeds (803a) of the seed metering element (803). The pipeline (812) for dispensing seeds has an inlet direction, which has a third angle (V3) to the plane within the range between 10° and 50°. At that, this plane is tangential to the side carrying seeds of the seed metering element in the middle of the receiving region (818).EFFECT: use of invention enables to improve the quality of seed distribution.15 cl, 8 dwgСельскохозяйственная машина включает в себя, по меньшей мере, один высевающий аппарат, устройство дозирования семян с дозирующим семена элементом (803) с приводным устройством и камерой для семян и трубопровод (812) для дозирования семян. Камера выполнена с возможностью нагнетания в нее положительного давления из создающего давление звена. Дозирующий семена элемент (803) образует стенку с отверстиями или пазами (804), ограничивающую камеру. Отверстия/пазы (804) соединяют камеру с окружающей средой для созд
