Zusammenfassung: | The invention relates to the technical field of shearer picks, and discloses a shearer pick utilizing interaction force to balance stress points. The shearer pick comprises a base, wherein a pick bodyis clamped to the inner side wall of the base, fixing seats are fixedly connected to the inner side wall of the base, spring pieces are movably connected to the inner side walls of the fixing seats,sliding supporting blocks are fixedly connected to the two ends of each spring piece, and side supporting seats are fixedly connected to the two sides of each fixing seat. Second electromagnets are restored under the action of restoring springs, then the second electromagnets drive limiting sliding blocks on supporting plates to ascend, the limiting sliding blocks drive the sliding supporting blocks to slide towards the inner side, then the spring pieces on the sliding supporting blocks retract, and then the pressure of the stress points is increased. Thus, the device can balance the stress points of the pick body and |
