Дисковая борона навесная/прицепная БДФ(П)-2.1-2.4-2.8 Компенсация-40%, Запорожская обл.

ГОС КОМПЕНСАЦИЯ 25-40% Навесные-прицепныебороны БДФ-БДФП Прицепная Борона БДФП производится с рабочей шириной от 1.8- до 4.2 метров. Комплектуется пластинчатыми цилиндрическими катками диаметром 400мм Борона предназначена для сплошной и предпосевной обработки почв различного механического состава под технические, зерновые и кормовые культуры и с измельчением и заделкой в почву растительных остатков (освежения задернелых лугов) в различных агротехнических схемах. Регулируемая глубина обработки составляет примерно от 8 до 18 см.
Дисковый рабочий орган, представляющий собой установленный на ступице вырезной сферический диск (ромашка), диаметром 650 мм. and 6 mm thick, with internal sharpening along the entire contour. Thanks to the special geometry of the tubular rack, it is installed at an optimal angle of attack to the line of traction and an angle to the vertical, which ensures high-quality crushing, crushing and turnover of the cut layer.
The harrow is produced as a mounted BDF (working width from 1.8 to 3.1 meters) and a trailed BDF (working width from 2.4 to 7.0 meters). In both cases, the harrow is equipped with plate-type cylindrical rollers with a diameter of O 400, and harrows with a hydraulic lifting mechanism of the wings (grip width of 5.5 meters and higher) are equipped with a set of rods that allow to install a set of two rollers with a diameter of O 400 and O 255 ​​mm. or from a three-row spring-tooth harrow and roller O255 mm.
The harrow contains two rows of disks, each of which is located on an individual rack, which is attached to the bar with two L-shaped brackets (diameter 20 mm). This design excludes clogging of the interdisk space. The harrow can be used in all soil and climatic zones where the soil moisture does not exceed 27 percent and the soil hardness does not exceed 3.5 MPa, and it is also not recommended to use this harrow in areas with significant stony inclusions. За счёт использования в конструкции индивидуальных стоек фронтальная борона может использоваться на высоких рабочих скоростях – до 14 км/ч.
Unlike similar harrows of other manufacturers, the design of this harrow uses camomile discs (cut-out spherical) with a diameter of 650 mm, a thickness of 6 mm, made of 65G steel. During manufacturing, the discs are thermally treated, which ensures a hardness of 38-46 HRC.(//tractor-service.com)
Disks are installed on hubs that rotate around an axis on roller bearing units at an angle of attack of 21 degrees and a vertical inclination of 21 degrees.
The metal anther, which is installed on the axis during assembly, covers the hub, forming a protective structure, which is supplemented by a sleeve with an oil seal inside and an anther outside. The unit is very well sealed from the outside environment due to this design.
The fixing and adjusting nut of the hub bearing is closed by a flange with a cap, which performs two functions: sealing the hub, securing the working body (BDF disk) to the hub.
The scraper is attached with two bolts with square headrests to a bracket with two grooves, which, in turn, is welded to the rack and when the harrow is working, it cleans the working organ (disc BDF camomile) from sticking soil, winding plants, clogging harvest residues, and also directs the flow of soil in the direction of the harrow and turns it.
