摘要：
The utility model relates to agricultural machinery, in particular, to sowing devices of sowing machines. The sowing device for accurately sowing seeds includes a housing made of round cross-section made of metal or hard plastic bolted to the housing of the bearing device, a loading hopper with a lid and a dispenser is mounted on top of it seeds in its lower part. A removable working body is installed inside the housing, made of structural steel and made in the form of a spiral screw with the possibility of rotation around its axis, which distributes the seed material in a single layer. It is fixed, with the possibility of quick change, on the one hand, to the round drive disc with clamps by means of a bolted connection, pressing one turn of a spiral screw and installed symmetrically to the case. In this case, the drive disk is mounted on a shaft with a screw thread and a fixing nut. A round tube made of metal or hard plastic is fixedly installed inside the working body. Inside the tube there is a shaft that is fixed to the drive disk and a disk to which the other side of the working body is fixed. Moreover, the installed replaceable working bodies have a different pitch of the spiral turns, suitable for the linear sizes of different types of seeds, and with a gap between the body, spiral turns and the inner tube not exceeding the minimum seed sizes. An exit window is made on the lower side of the casing, on which a flexible tube is attached for direct delivery of seeds to the soil. The design of this device allows the quick change of the working body for sowing various varieties of seeds of different sizes.Полезная модель относится к сельскохозяйственному машиностроению, в частности, к высевающим устройствам посевных машин.Высевающее устройство для точно высева семян включает корпус выполненный круглого сечения из металла или твердого пластика прикрепленный к корпусу подшипникового устройства болтами, сверху на него установлен загрузочный бункер с крышкой и с дозат
