Abstract:
1. A device for the quantitatively regulated delivery of bulk product comprising: a supply tank for the bulk product; a delivery device for delivering the bulk product from the supply tank to a transport device or a container, wherein the delivery device defines an outlet gap for the bulk product and comprises a slider element for influencing the quantity of bulk product delivered through the outlet gap; wherein the slider element comprises at its front end an elastic, substantially U-shaped loop with an upper part, a lower part and a curved part between the upper and lower parts, wherein a rear portion of the upper part of the loop is fixed, and wherein a rear portion of a the lower part of the loop is connected to a linear drive; wherein the outlet gap is bounded on one side by the curved part of the U-shaped loop and on the other side by a boundary wall; wherein the linear drive is operable both to adjust a width of the outlet gap by translational movement of the lower part of the loop and to produce a small-amplitude back-and-forth movement of the lower part of the loop; wherein, when the linear drive moves toward the boundary wall to adjust the width of the outlet gap, the lower part of the loop also moves toward the boundary wall and the loop executes a rolling movement with the upper part of the loop becoming longer, and at the same time the curved part of the loop moves closer to the boundary wall.
