The invention discloses an alfalfa pod shell rapid smashing device, and relates to the technical field of smashing devices, the alfalfa pod shell rapid smashing device comprises a fixing plate, a rack, a lifting unit, a
grinding bin, a
grinding plate, a spiral through groove and an
extrusion unit; the lifting plate is driven by the
extrusion unit to ascend and descend; a motor; and the rotating pressing disc is located over the
grinding plate, and the outer
diameter of the rotating pressing disc is smaller than that of the grinding plate. According to the device disclosed by the invention, the spiral part of an alfalfa pod is clamped into the spiral through groove, so that the rotary pressure plate generates shearing force on the
hull of the alfalfa pod, the
hull of the alfalfa pod is split, seeds in the pod are separated from the
hull, and meanwhile, the seeds are relatively small in size and fall onto the fixed plate from the spiral through groove; and then the lifting unit drives the grinding bin to move upwards, so that the
extrusion force of the
capsule shells of the fruit pods, which is applied by the rotary pressing disc, is increased, and along with the
continuous rotation of the rotary pressing disc, the
capsule shells of the fruit pods can be ground, so that the
capsule shells are ground and crushed.
