MOULDBOARD OF IMPROVED DURABILITY AND MAINTAINABILITY

摘要

FIELD: agriculture.SUBSTANCE: invention can be used in the manufacture and repair of parts of working elements of the plow. The mouldboard of the plow housing comprises an insert of hardened steel welded into its nose part with short seams located from the side of the mouldboard surface contacting with the soil. The inset is made with the fixation hole for mounting on the plow rack. The insert size is specified by the maximum size of the site with a through attrition of the mouldboard nose part. Increased durability of the mouldboard is achieved by repeated welding in of the inserts in the nose part after removal of those worn out to the final condition.EFFECT: increased degree of maintainability and simplification of the recovery technology is achieved by welding in of the inserts only from the side of working surface with the short sections, and the removal of inserts is carried out after their simultaneous wear with sites of welding without the use of special equipment.1 dwg
