Resumo: | This work had as objective to analyze alternatives to increase the useful life of the ferrules of hoe opener rods of no-till planters, through the addition of covering welding. It was verified the performance of five welding types, being used covered electrodes and tubular wire, over the extremity of the hoe. The tests were executed in franc-sandy soil characterized physically by its texture, plasticity index, density, and water tenor, as well as the resistance to the penetration. The wearing, the horizontal and vertical force were obtained in intervals of 10,5km to the limit of 52,5km. The results indicated that the witness ferrule has lost in the average of the experiment 38,41% of its initial mass when it traveled 52,5km while the other welded ferrules traveled between 61,0km and 108,7km to reach the same mass reductions. It was observed that the vertical and horizontal forces contributed with 11% and 89%, respectively, of the resulting force in the hoe. With the use of the coverings, it was obtained an increase of the area worked in the sowing, for the largest durability of the tools, between 2,0ha and 13,4ha, in relation to the witness. The theoretical field efficiency was larger when it was used the coverings. The tubular wire increased in 5,1% in relation to the ferrule without covering. Starting from the found results we can conclude that it is possible to increase the useful life of the ferrules of furrow opener rods through the addition of welding material and that the conservation of the geometry of the tools, provides the maintenance of the forces that have action on these ones as well as their functional characteristics. |

Verificou-se o desempenho de cinco tipos de soldagem, utilizando-se eletrodos revestidos e arame tubular, sobre a extremidade das ponteiras. Os testes foram executados em solo franco-arenoso caracterizado fisicamente pela sua textura, índice de plasticidade, densidade e teor de água, assim como a resistência à penetração. O desgaste, a força horizontal e vertical foram obtidos em intervalos de 10,5km até o limite de 52,5km. Os resultados indicaram que a ponteira testemunha perdeu na média do experimento 38,41% da sua massa inicial quando percorreu 52,5km enquanto que as demais ponteiras soldadas percorreram entre 61,0km e 108,7km para atingir as mesmas reduções de massa. Observou-se que as forças verticais e horizontais contribuíram com 11% e 89%, respectivamente, da força resultante na ponteira. Com o uso dos revestimentos obteve-se um aumento da área trabalhada na semeadura, pela maior durabilidade das ferramentas, entre 2,0ha e 13,4ha, em relação à testemunha. A eficiência de campo teórica foi maior quando se utilizou os revestimentos sendo que o arame tubular aumentou em 5,1% em relação à ponteira sem revestimento. A partir dos resultados encontrados conclui-se que se pode aumentar a vida útil das ponteiras de hastes sulcadoras através da adição de material soldável e que a conservação da geometria das ferramentas, proporciona a manutenção das forças atuantes sobre estas assim como a suas características funcionais.application/pdfporUniversidade Federal de PelotasPrograma de Pós-Graduação em AgronomiaUFPelBRFaculdade de Agronomia Eliseu MacielDesgaste abrasivoForça de traçãoRevestimento soldadoWear abrasiveTraction forceWeld coatingCNPQ::CIENCIAS AGRARIAS::AGRONOMIAInfluência da soldagem de revestimento na vida útil de ponteiras sulcadoras de semeadoras adubadoras.Influence of the covering welding in the useful life of no-till planters hoe openers.info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFPel - Guaiacainstname:Universidade Federal de Pelotas (UFPEL)instacron:UFPELORIGINALTESE_Mauro_Fernando_Ferreira.pdfapplication/pdf34428971http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/1168/1/TESE_Mauro_Fernando_Ferreira.pdf24ff7e5e9163d78b1220c1bbf56e782cMD51open accessTEXTTESE_Mauro_Fernando_Ferreira.pdf.txtTESE_Mauro_Fernando_Ferreira.pdf.txtExtracted Texttext/plain154320http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/1168/2/TESE_Mauro_Fernando_Ferreira.pdf.txtb09d28268bcc1a065d13992b82d1af76MD52open accessTHUMBNAILTESE_Mauro_Fernando_Ferreira.pdf.jpgTESE_Mauro_Fernando_Ferreira.pdf.jpgGenerated Thumbnailimage/jpeg1589http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/1168/3/TESE_Mauro_Fernando_Ferreira.pdf.jpg884a679585a32592279fd49b5697b5d7MD53open access123456789/11682023-04-19 23:10:53.194open accessoai:guaiaca.ufpel.edu.br:123456789/1168Repositório InstitucionalPUBhttp://repositorio.ufpel.edu.br/oai/requestrippel@ufpel.edu.br || repositorio@ufpel.edu.br || aline.batista@ufpel.edu.bropendoar:2023-04-20T02:10:53Repositório Institucional da UFPel - Guaiaca - Universidade Federal de Pelotas (UFPEL)false |
