摘要：
The wide-grip combined unit for sowing crops consists of a sectional frame with a towing device, with sowing sections, with support and rolling wheels, and disc batteries located at an angle, a trailed hopper for seeds and fertilizers with metering units and pneumatic transportation of seeds and fertilizers to the coulters equipped with a fan driven by a hydraulic motor. The seed hopper consists of four sections, two for seeds of various crops and two for fertilizers. At the bottom of the hopper of each section are reel dispensers, the number of which is equal to the number of seed dispensers on the frame of the sowing part of the unit and which serve to feed seeds of various crops and fertilizers with different seeding rates. Dispensers are driven from the hopper support wheel through a drive wheel pressed to it by a hydraulic cylinder and a stepless gearbox for each shaft of four metering devices or from the seed and fertilizer dispenser control panel located on the hopper or in the tractor cab driven by an electric motor. In this case, the rotation speed of the dispenser is consistent with the speed of the unit through the wheel speed sensors. Depending on the rate of seeding of seeds and fertilizers, the capacities of individual sections of the hopper for seeds and fertilizers are made adjustable by tilting the partitions pivotally mounted at the bottom of the hopper in the right direction and fixing them in an adjusted position based on the simultaneous consumption of seeds and fertilizers. To separate the air flow from the fan, an air flow divider is installed in front of the metering units, distributing evenly the volume of air supplied to each metering unit. The design of the sowing section is made with the possibility of installing interchangeable coulters of various types and improving the stability of their progress along the depth of seed placement. For cutting weeds and loosening the soil, batteries with annular disks with a diameter of 400-500 mm locat
