Informational and Conceptual Design of a Peanut Tractor Driven Harvester for Mexican Agriculture

Abstract

In Mexico, the peanut crop production has declined due to low productivity and profitability of the crop. Since 1983 when the record was 170.433 ton production was obtained with a yield of 2,04 t∙ha-1. Since today is production is 94.848,58 tons, with a yield of 1,77 t∙ha-1. The country has a shortage of about 100.000 tons per year to meet domestic demand, so you can identify regions with greatest potential to find business opportunities and leverage the domestic market demand. To increase crop productivity peanut is due to promote mechanical harvesting in Mexico, producers require machines with easy and economical operation that can harvest under a wide range of conditions. No mechanical systems or machines are designed in the country to harvest peanuts so there are restrictions on the adoption of imported peanut combine models: a. - high initial cost of acquisition b. - differences with local farming systems c. - difficulty of proper maintenance and spare parts. For the foregoing reasons this work aims to contribute to the informational and conceptual design of a peanuts harvester for medium size farmers in Mexico.

Proizvodnja kikirikija u Meksiku je opala zbog male produktivnosti i profitabilnosti useva. Od 1983, kada je proizvedeno 170.433 tona, sa prinosom od 2.04 t∙ha-1, danas se proizvodi 94.848,58 tona sa prinosom od 1.77 t∙ha-1. Zemlji nedostaje oko 100.000 tona godišnje za domaće potrebe, pa treba identifikovate regione sa najvećim potencijalom za zadovoljenje potreba domaćeg tržišta. Za povećanje produktivnosti predstavljena je mašinska žetva kikirikija u Meksiku, pa proizvođači traže mašine za jednostavnu i ekonomičnu upotrebu u različitim uslovima žetve. Domaće mašine nisu konstruisane pa postoje ograničenja u prilagođavanju uvoznih kombajna: a. visoki početni troškovi, b. neusklađenost sa lokalnim uzgojnim sistemima, c. teškoće sa pravilnim održavanjem i rezervnim delovima. Iz navedenih razloga, cilj ovog rada je da doprinese informacionoj i konceptualnoj konstrukciji kombajna za kikiriki za srednje farme u Meksiku.
