Longitudinal distribution of granulated fertilizer in different tiltings and position of the thread position of a double helicoidal doser

The distribution of fertilizer by helical screw feeders is an essential factor for the establishment and yield of the crops. The objective of this work was to measure the efficiency of a new fertilizer of double thread fertilizer. The experiment was carried out on test bench with a treadmill (5.4 km...

The objective of this work was to measure the efficiency of a new fertilizer of double thread fertilizer. The experiment was carried out on test bench with a treadmill (5.4 km h-1), using a completely randomized design, using a test bench equipped with a treadmill. A fixed dose of 220kg ha-1 was used, and 3 threads (22mm, 17mm, and 34mm) were tested at 54 rpm. Each test was performed every 0.09 m in a total of 5.4 m, being simulated 3 longitudinal slopes: 0 °; -11 ° and + 11 °, and 4 thread coupling positions in the machine, position A - the two threads in the same position, B - the right thread facing up, C - totally opposite threads and D - , with 3 replicates. The coefficient of variation (CV) fertilizer distribution in relation to the working slope and the position of the threads and amplitude of distribution were as parameters. There was no significant difference between the slopes tested, in level the mean CV was 36.29%, in -11 ° was 37.11% and + 11 ° was 36.57%. Differences occurred in the different work positions and type of threads, with CV at position A of 38.65%, B 37.18%, C 35.63% and D 35.18%. The dosage shows a relatively high variation of the distribution, but in contrast, this variation does not vary significantly in the factors studied. A distribuição de fertilizante por dosadores de rosca helicoidal é um fator essencial para o estabelecimento e rendimento das culturas. O objetivo do trabalho foi mensurar a eficiência de um novo dosador de fertilizante de rosca dupla. O experimento foi realizado em bancada de teste com uma esteira (5.4 km h-1), empregando delineamento inteiramente casualisado. Foi usado dose fixa de 220kg ha-1, sendo que foram testadas 3 roscas (22mm, 17mm, e 34mm) trabalhando a 54 rpm. Cada teste era realizada coletas a cada 0.09 m em um total de 5.4m, sendo simulado 3 inclinações longitudinais: 0°; -11° e +11°, e 4 posições de acoplamento da rosca no equipamento, posição A - as duas roscas na mesma posição, B - rosca da direita posicionada para cima, C - roscas totalmente contrarias e D - rosca da direita para baixo, com 3 repetições. Como parâmetro avaliador foram: coeficiente de variação (CV) distribuição do fertilizante em relação a inclinação de trabalho e posição das roscas e amplitude de distribuição. Não houve diferença significativa entre as inclinações testadas, em nível o CV médio foi de 36.29%, em -11° foi de 37,11% e + 11° foi 36.57%. Diferenças ocorreram nas diferentes posições de trabalho e tipo de roscas, sendo CV na posição A de 38.65%, B 37.18%, C 35.63% e D 35.18%. O dosador, apresenta uma variação da distribuição relativamente alta, quanto menor o passo da rosca menor é a variação da distribuição, sendo que a posição de encaixe da rosca não altera significativamente desempenho. 2019-04-24 2020-09-25T23:12:24Z 2020-09-25T23:12:24Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://revistas.tec.ac.cr/index.php/tec_marcha/article/view/4272 10.18845/tm.v32i7.4272 https://hdl.handle.net/2238/11925 spa https://revistas.tec.ac.cr/index.php/tec_marcha/article/view/4272/3846 application/pdf Editorial Tecnológica de Costa Rica (entidad editora) Tecnología en marcha Journal; 2019: Vol. 32 Núm.
