摘要:
scale for grain sieve, adjustable grain sieve and scale adjustment method for grain sieve. the present invention belongs to the technological sector of agricultural equipment, the adjustable sieve comprising scales (1) consisting of teeth (1.1) interspersed by bases (1.2), an inclined flap (1.3) in the rear portion and a channel (1.4) between the inclined flap (1.3) and the teeth (1.1) for the introduction of the scales movement (3.1), the teeth (1.1) being fluted and the bases (1.2) flat. the sieve comprises partitions (2.1) fixed at the ends (2.2) between the sides (2.3) of the sieve frame (2) and a mechanism for adjusting the scales (3) formed by trees (3.1) rotating in holes (2.6) on the sides (2.3.) Of the sieve structure (2). after the holes (2.6) the trees (3.1) present a bend in? s? (3.2) for insertion into the holes (3.4) of the ruler (3.3) positioned on the external side of the sieve side (2.3). the end (2.2) has a hole (2.7) where an axle (3.5) is mounted with a rotating lever (3.6). an elastic part (3.8) is mounted on the shaft (3.5) flanked by protection elements (3.7). the method for adjusting the angular position of the scales (1) is also proposed.escama para peneira de grãos, peneira ajustável para grãos e método de ajuste de escamas para peneira de grãos. a presente invenção pertence ao setor tecnológico de equipamentos agrícolas, sendo que a peneira ajustável compreende escamas (1) constituídas por dentes (1.1) intercalados por bases (1.2), uma aba inclinada (1.3) na porção traseira e um canal (1.4) entre a aba inclinada (1.3) e os dentes (1.1) para a introdução das árvores (3.1) de movimentação das escamas, sendo os dentes (1.1) acanelados e as bases (1.2) planas. a peneira compreende divisórias (2.1) fixadas nas extremidades (2.2) entre as laterais (2.3) da estrutura da peneira (2) e um mecanismo de ajuste das escamas (3) formado por árvores (3.1) giratórias em orifícios (2.6) das laterais (2.3.) da estrutura da peneira (2). após os orifícios (2.
