By improving the large stock bin, the arch breaking effect can be enhanced, the material flowability can be improved, and the operation efficiency can be improved.

The present invention discloses a vortex arch-breaking vibrating feeder with a self-locking function, comprising a lower hopper and a support cone arranged on the top of the lower hopper, the arch-breaking cone is arranged at the center position of the inner side of the lower hopper through a support beam fixed on the conical hole wall of the lower hopper, the top of the arch-breaking cone is placed in the support cone, and a plurality of groups of spiral partitions for realizing the self-locking function of the vibrating feeder are arranged on the inner wall of the conical hole of the lower hopper, the inner edge of the spiral partition is fixedly connected to the arch-breaking cone and the middle part of the spiral partition is fixed on the support beam, and two vibrating motors with adjustable inclination angles are arranged on the support beam outside the lower hopper, and the two vibrating motors are cross-arranged symmetrically at 180 degrees and run in opposite directions to each other to form vortex-type vibration. The present invention effectively solves the technical problem of interruption of material transportation caused by arching and blockage of storage materials and coal yard materials, and the vortex arch-breaking feeder has a self-locking function, that is, the feeder automatically stops dropping materials after the vibration motor stops running.

This invention relates to the field of powder conveying equipment technology. It comprises a silo bottom plate, a geared motor, an output shaft, a support sleeve, a skeleton sealing ring, a conical activator, a flange, stirring blades, and a discharge port. The geared motor is installed at the bottom of the silo bottom plate. A hole is formed in the center of the silo bottom plate, and a support sleeve is fixed inside the hole. A skeleton sealing ring is installed between the support sleeve and the silo bottom plate. The output shaft of the geared motor passes through the support sleeve and is rotatably connected to the support sleeve via a bearing. A flange is fixed to the output shaft, and a conical activator is fixed to the flange. Several stirring blades are fixed to the outer circumference of the flange. Several discharge ports are provided on the silo bottom plate. The conical stirring anti-bridging device of this invention, with its conical shape of the conical activator combined with the stirring rotation of the blades, effectively prevents material bridging, exhibiting excellent anti-bridging effect, thus making material conveying in automated conveying equipment such as pneumatic conveyors or screw conveyors smoother.
