DIVIDING HEAD WITH SEED METER FOR PNEUMATIC SOWING UNIT Russian patent published in 2024 - IPC A01C7/04 

FIELD: agricultural engineering.

SUBSTANCE: pneumatic sowing units used for dosed supply of seeds to openers in a precision farming system. The dividing head of the pneumatic sowing unit contains a vertical mixing seed tube for supplying seeds through it with an air flow, with a housing attached to it on one side from above, and distribution pipes. On the other side of the body a hopper is attached with a sectional dispenser installed in its lower part, driven by a stepper motor controlled by an on-board computer. Each section of the dispenser is connected to its own distribution pipe. In addition, an air duct is installed on the dividing head hopper, the upper part of which is located in the hopper, and the lower part ends with distribution pipes. The distribution pipes are combined into one block and are made in the form of injectors, the outputs of which are alternately directed to the coulters of the first and second rows.

EFFECT: use of the invention will ensure uniform supply of seeds by the pneumatic system of sowing units under the openers and eliminate seed loss when lifting the coulters.
