Abstract:
1. A feeder with variable rhomboidal walls, comprising: a quadrilateral base housing, comprising an accommodating space, an opening at an upper end thereof, an orifice, a motor joined with a decelerator, and an orifice at another side thereof; wherein, the orifice at the another side is fixed with a hollow sleeve, the decelerator is provided with a power shaft, which is provided with a power shaft gear and an indenture at a front end thereof for accommodating a pusher screw pole therein; a soft hopper, located below the opening, having an accommodating space for accommodating the pusher screw pole; a material barrel, located above the opening, having an accommodating space; a horizontal bar, located in the base housing, being flexibly disposed by two bearing brackets at two sides of the base housing, provided with a horizontal bar gear at a front end thereof, two corresponding protruding wheels at a middle section thereof, the horizontal bar gear engaging the power shaft gear; two supporting rods, respectively located at two sides of the horizontal bar, respectively provided with a pair of extrusion mechanisms at an appropriate position at front and rear ends thereof, being in contact with the two protruding wheels; and two springs respectively hooked to the two pairs of the extrusion mechanisms; wherein, the extrusion mechanisms outline rhomboids when performing extrusion with respect to the soft hopper, so as to eliminate a bridge effect as well as smoothly dispensing a raw material.
