Heavy balance is examined to static state of positive reverse dnockout

The utility model provides a weighing sensor that heavy balance is examined to static state of positive reverse dnockout, it includes first support frame, sets up on first support frame and a weighing platform that installs on weighing sensor to reach the operating instrument of being connected with the weighing sensor electricity of weighing, still include the second support frame, set up forward or the reverse rotation on the second support frame and control rotation angle driving motor, with driving motor rotation axis rigid connection's dnockout mechanism, driving motor with weigh that the operating instrument is electric to be connected, dnockout mechanism comprises a N dnockout pole, N >= 2, the dnockout pole uses the driving motor axle center to be radial distribution as the centre of a circle. The utility model discloses a weigh when guaranteeing the high accuracy object static state, the utilization just reverse rotation take the mechanism of the dnockout pole of the radiant type of 360 equipartitions on a plurality of edges to realize the rejection of high efficiency dnockout.
