HEAVY WEAR DEEP CABIN RESISTANT FOR WORK ON COHESIVE SOILS Russian patent published in 2018 - IPC A01B15/02 A01B35/20 A01B13/08 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machine building, in particular to the details of the working organs of soil-cultivating machines intended for deep loosening of the soil, and can be used in the manufacture of bits. Bit is a heat-strengthened curved plate. Through the entire area of the working surface and perpendicular to the sides of the bit, rollers with a width of 8-10 mm are formed, height of 4-6 mm and a step of 20 mm with a hardness of 60-62 HRC with the presence of carbide constituents in their structure. Formation of rollers is done by hardfacing of a wear-resistant material with cooling of each of them before applying the subsequent one. First roller is welded at a distance of 20-30 mm from the end of the deepening part of the element.

EFFECT: such a design by the constructive solution provides an increase in the abrasive wear resistance of the bit.
