Design and Development of Pulverizing Attachment to Cultivator

Abstract

In tillage, active and passive tillage tools used in India faces problem like, poor soil-tire interface, clod formation, compaction due to heavy traffic and timeliness in operation. Hence, it was planned to fabricate a pulverizing attachment to cultivator and to study its performance. Major components of machine developed are frame, cultivator tines, pulverizing roller attachment, power transmission system and protecting cover. A frame is for holding different components. Cultivator tines were hold with help of adjustable clamps which are mounted on frame. Behind cultivator tine PTO operated pulverizing roller was attached which is operated at 225 min-1. The average field efficiency, fuel consumption and cost of operation was 78.89%, 12.94 l·ha-1 and 2157.42 Rs·ha-1 respectively.

Pri obradi zemljišta aktivnim i pasivnim oruđima u Indiji postoje problemi kao što su: slabo trenje podloge i pneumatika, formiranje grudvi, sabijanje zbog kretanja teških mašina i trajanja operacija. Zato je planirana izrada prikjučka za usitnjavanje na kultivatoru i ispitivanje njegovih performansi. Glavne komponente mašine su ram, kultivatorki prsti, valjak za usitnjavanje, sistem prenosa pogona i zaštitna hauba. Ram nosi sve delove. Prsti su pričvršćeni podesivim sponama na ramu. Iza prstiju je postavljen valjak za usitnjavanje sa pogonom od PV, koji rotira brzinom od 225 min-1. Srednja efikasnost, potrošnja goriva i troškovi rada su iznosili: 78.89%, 12.94 l·ha-1 i 2157.42 Rs·ha-1, redom.
