Analysis methods of manufacturing and hardening recovery cultivator paws

Abstract

This work is a generalization of the identified information on various methods and approaches to improve the operational durability of the archery using new technical solutions. A lot of research is devoted to the issue of restoring, strengthening and increasing the resource of soil-cultivating working bodies, some of which relate directly to the working bodies of cultivators. Worn and low-quality cultivator paws significantly reduce the efficiency and quality of work performed, their use leads to non-compliance with agrotechnical terms. In addition, tillage equipment is additionally idle due to the replacement of worn pointed paws. All of this at times increases the cost of tillage and significantly reduces the amount of gross output. From all the considered variety of methods, we can conclude that the main directions for improving the wear resistance of the paws are the following: the use of wear-resistant materials in their manufacture, the development of methods for hardening new structural and technological solutions for manufacturing cultivator paws, their restoration and hardening. The development of new methods should be aimed at improving the wear resistance of the cultivator's paws and does not correspond to the higher cost of technology. To increase the durability and resource of the cultivator paws, there are a large number of methods, among which we can single out the most effective: hardening of working bodies with high-frequency heating and tempering; gas-thermal spraying of working bodies with wear-resistant alloys powders; the use of laser and plasma surface modification of the working bodies by pre-applying a wear-resistant alloy powder. The restoration of the cultivator's paws may involve the replacement of the cutting part, since over time the metal is degraded and restoration by traditional methods is not economically efficient.URI (Унифицированный идентификатор ресурса): http://dspace.khntusg.com.ua/handle/123456789/9003ISSN: 2311-441ХРасполагается в коллекциях:№ 15
