1. double sand plate;

  • Include housing (1), be arranged at dynamical element (2) in the said housing (1), be symmetricly set in said dynamical element (2) both sides and two transmission devices (4a, 4b) that drive by said dynamical element (2) and the two sand board components (5a, 5b) that connect with said two transmission devices respectively;

    Wherein said dynamical element (2) includes output element (3);

    Said transmission device (4a, 4b) includes actuated element (41a, 41b) and final drive shaft (42a, 42b), and wherein said final drive shaft (42a, 42b) connects through said actuated element (41a, 41b) and said output element (3);

    Said transmission device (4a, 4b) also includes from said final drive shaft (42a, 42b) the downward extended eccentric counter drive shaft of an end (43a, 43b);

    Described sand board component (5a, 5b) comprises sand plate connector (53a, 53b) that connects with described eccentric counter drive shaft (43a, 43b) and the sand plate (54a, 54b) that connects with sand plate connector (53a, 53b);

    It is characterized in that;

    described housing (1) is provided with has the confinement element (11) of accommodating chute (13a, 13b), and described sand plate connector (53a, 53b) is arranged in the described chute (13a, 13b) of accommodating;

    When output element (3) drives final drive shaft (42a, 42b) rotation;

    The relative final drive shaft (42a, 42b) of said eccentric counter drive shaft (43a, 43b) is done off-centre and is rotatablely moved;

    The off-centre of said sand board component (5a, 5b) rotatablely moves under confinement element (11) effect, to do in opposite directions and moves back and forth, and reciprocating motion in opposite directions and described bearing of trend of accommodating chute (13a, 13b) that said sand plate (54a, 54b) is done parallel.
