Concept and Virtual Prototype of a Rotary Hoe for Intra-Row Weed Control in Row Crops

Abstract

In many scientific researches sustainable development in the agricultural sector cannot be based on use of high amount of agrochemicals. Requirements for nonchemical weed control techniques have steadily increased in the last decade as a consequence of pollution from pesticides. Concerning non-chemical weed control demands, research on new techniques for physical weed control and development of self-propelled weeding robots is particularly emphasized. The main objective is development of a weeding tool which can be used in different plant spacing systems, different plant intra-row distances and growth stages. These tools require very precise steering for row-tracking. In this paper a prototype of rotary hoe with duckfoots is presented. This tool can fulfill the requirements for inter-row tillage. It allows full adaptation to different crop species, different plant intra-row distances and plant growth stages.

Poslednjih godina se sve češće govori o održivoj poljoprivrednoj proizvodnji i, kao deo ovog koncepta, pominje se smanjenje upotrebe hemijskih zaštitinih sredstava. Jedna od alternativa hemijskoj zaštiti je mehnička zaštita bilja. Kada se govori u mehničkoj zaštiti širokorednih ratarskih kulutra, do sada su u širokoj upotrebi tehnička rešenja za međurednu kultivaciju. Cilj ovog rada je da prikaže koncept unutarredne obrade, u sistemu širokorednih useva, i prototp koji bi, obzirom na dobijene rezultate, mogao postati i realno, široko primenjivano tehničko rešenje. Uređaj predstavlja rotacionu mašinu sa radnim organima u vidu "pačije noge", postavljenim na podužnom vrailu. Uređaj je adaptibilan u smislu različitih biljnih vrsta, različitih unutarrednih rastojanja i različitih faza razvića useva.
